Description

  The present invention relates to a wheel brush used for various types of processing of a surface to be processed.

  For the conventional wheel brush, various improvements are made according to the purpose of use, for example, a large number of wire bristle materials are arranged radially and fixed in the center to form a disk with a certain thickness, Japanese Patent Application Laid-Open No. 10-564 discloses a technique of forming a wheel brush by adhering between individual wires with a filler rich in elasticity.

  JP-A-10-564

  With respect to conventional wheel brushes, for example, techniques having various characteristics as described above have been disclosed. However, in order to prevent the wires from being scattered, the fillers are fixed between individual wires. However, when the wheel brush is brought into contact with the surface to be processed, the adhered filler is peeled off from the wire and adheres to the surface to be processed, so that the attached filler needs to be separately cleaned. In addition, the processing performance may be deteriorated by the attached filler. In addition, since the wheel brush uses a single wire, after the filler is peeled off, the cutting performance of the wire is rapidly deteriorated due to breakage and deformation of the wire. Furthermore, after the brush is formed, a manufacturing method in which individual wires are fixed with a filler is adopted, so that the manufacturing procedure is complicated, and the material for the filler and the cost for manufacturing are required. Had.

  The present invention has been made in order to solve the above-described problems, and when performing various types of processing such as grinding, polishing, surface treatment, cleaning, deburring, etc. on the surface to be processed, in the case of poor processing conditions. In addition, the brush piece does not break, the processing performance is not deteriorated even when the brush piece is deformed, and the object is to provide a wheel brush with a simple structure and manufacturing procedure. .

The wheel brush according to the present invention is configured as follows.
(1) In the wheel brush for performing various types of processing, the wheel brush is formed of at least a core material and a brush piece, and the core material includes a hole portion 70 and a center where the plurality of brush pieces are sandwiched. A flange 2B in which a hole 60 is formed , a flange 2C in which a hole is formed, and a flange 2A in which a cylindrical end is formed at a position corresponding to the hole of the flange 2C, the brush pieces, strands only, or Ri Oh is formed from twisted and single wire, the approximate central portion of the plurality of brush pieces, sandwiching the hole 70 of the flange 2B, the end of the flange 2A, the While being inserted into the hole portion 60 of the flange 2B, the hole portion of the flange 2C is passed through and fixed to the end portion of the flange 2A.

  (2) In the wheel brush having the configuration described in (1) above, the wheel brush is composed of a plurality of types of brush pieces, and the heights of the plurality of types of brush pieces are the same or different. It has been done.

  (3) In the wheel brush having the configuration described in (1) or (2) above, the twist at the tip of the stranded wire is loosened.

(4) In the wheel brush having the configuration described in any one of (1) to (3) above, a cross section of at least one single wire constituting the stranded wire is formed in a polygonal shape or a cylindrical shape. Is.

(5) In the wheel brush having the configuration described in any one of (1) to (4) above, the stranded wire has a coating layer formed thereon.

  The wheel brush of the present invention can obtain the following effects. In the description, the same reference numerals as those in the claims are attached.

  (1) The wheel brush is formed so that the brush pieces are twisted and then twisted after bundling a plurality of single wires. Therefore, the wheel brush can absorb and disperse the reaction force such as the impact force received by the brush piece from the surface to be processed by the stranded wire. For this reason, the brush piece can be prevented from being broken, and even when the brush piece is deformed, the processing performance is not deteriorated. Further, since the hair breakage and deterioration can be prevented, a highly durable wheel brush can be manufactured.

  Moreover, since the brush piece is formed of a stranded wire, the brush piece can generate fluff due to the twisting of a plurality of single wires. For this reason, the brush piece is less prone to hair flaws and can prevent hair breakage. Moreover, since it is hard to have a fuzz, even when a wheel brush is used for a long time, the outer diameter of the brush piece before use can be maintained. Therefore, the wheel brush can have high durability. Moreover, since the front-end | tip part of a strand wire contacts the to-be-processed surface, the brush piece may be in the state where the twist of the front-end | tip part was loosened a little at the time of contact. Therefore, for example, in the deburring process, the deburring can be performed uniformly at any position on the processing surface.

  Furthermore, since the wheel brush is formed in a stranded wire shape, for example, the wire brush is formed in a stranded wire shape by adopting an ultrafine fiber having a diameter of 0.1 mm or less as a single wire. Depending on the condition, the formation state of the brush piece can be set to be optimal and used. When a stranded wire made of ultrafine fibers having a diameter of 0.1 mm or less is used for a single wire, it can be optimally used for deburring of a work surface on which a very fine flash is formed.

  Further, the wheel brush is formed of a core material and a brush piece, and after sandwiching the approximate center portion of the plurality of brush pieces into the hole portion of the flange, after sandwiching the flange from both sides, pressurize, Since it is formed by caulking and fixing, it is possible to form the brush pieces radially densely around the axis of the core material. Therefore, even if the processing surface is difficult to process compared to a flat surface, such as a cylindrical inner surface, a micro hole, or the inner part of a tube, various processing such as grinding, polishing, surface treatment, cleaning, deburring, etc. Can be implemented optimally. Further, the structure and the manufacturing procedure can be simplified as compared with a flocking method such as flat line flocking or round line flocking. In addition, since the wheel brush is formed by twisting a brush piece made of a stranded wire radially around the axis of the core material, the side surface of the almost central portion of the pinched brush piece The concavo-convex shape of the surface of the stranded wire formed in is bent into the flange. Therefore, it is possible to produce a wheel brush that is less likely to lose hair than a single wire.

  In addition, when the wheel brush is brought into contact with the work surface, the tip of the brush piece that comes into contact with the work surface is loosened by a predetermined dimension, and when the brush piece is separated from the work surface, The material of the single wire which comprises a brush piece, detailed shape, the twist condition of a brush piece, etc. can be set so that twist may return. In the case of the setting as described above, the tip portion of the brush piece that has been loosely twisted is divided into a plurality of single wires. Therefore, the split single wire comes into contact with the surface to be processed and enters the extremely fine uneven shape, the back, or the fine hole of the surface to be processed, for example, processing such as deburring, It can be carried out optimally without leaving any processing. Further, since the twist returns when the brush piece is separated from the surface to be processed, the tip portion can always be brought into contact under the same conditions. Therefore, the wheel brush can have extremely high durability.

  In addition, the wheel brush is arranged so that when the brush piece is brought into contact with the work surface, the looseness of the twist at the tip of the brush piece gradually changes with time to contact the work surface. It is possible to set the material, detailed shape, and twist condition of the brush piece. In the case where the setting as described above is performed, the tip of the brush piece gradually changes in the twist with the time of contact with the surface to be processed, so that the processing time increases. The tip of the brush piece gradually changes and comes into fine contact with the surface to be processed. Therefore, even if the surface to be processed is rough, it is not necessary to use the wheel brush for rough finishing, intermediate finishing, precision finishing, etc. in order, and the surface to be processed in the rough state can be precisely made with one wheel brush. Can be processed so that The above setting is suitable for polishing the surface to be processed, surface treatment, and deburring.

  The wheel brush can be used by untwisting the outer tip of the brush piece by a predetermined dimension. As described above, when untwisted and used, a brush part having a generally spiral shape formed by twisting is formed at the outer tip of the brush piece. It is possible to touch a brush piece that is high and that has a supple hair. Therefore, even when a complex uneven shape or a minute hole is formed on the surface to be processed, the brush portion having a generally spiral shape formed at the outer tip of the brush piece has a complicated uneven shape, Alternatively, it can enter a minute hole and process it quickly and accurately. The above setting is suitable for polishing, cleaning, surface treatment, and deburring of the work surface.

  Moreover, since the brush piece is radially formed around the axis of the substantially cylindrical core material, the wheel brush can be rotated at a high speed and brought into contact with the work surface. Therefore, even when the area of the work surface is very large, polishing, cleaning, surface treatment, or deburring of the work surface can be performed quickly and accurately.

  In addition, a predetermined number of wheel brushes can be used depending on the purpose of use. For this reason, the number of wheel brushes to be stacked can be set at an appropriate time so that optimum processing can be performed even when the processing width of the surface to be processed is wider than the thickness of the wheel brush. Therefore, even when the width of the work surface is wide, polishing, cleaning, surface treatment, or deburring of the work surface can be performed quickly and accurately.

  (1) As another embodiment, when a wheel brush in which a stranded wire brush piece and a single wire brush piece are radially formed on the outer periphery of the core material is used, the wheel brush is processed. A stranded wire brush piece and a single wire brush piece can be brought into contact with the surface. Therefore, when processing the surface to be processed, such as grinding, polishing, surface treatment, cleaning, deburring, etc., even if the surface to be processed has various different processing conditions, the stranded wire having different processing performance Therefore, the wheel brush can have the optimum grinding, polishing, surface treatment, cleaning, and deburring performance according to the purpose of use. As the different processing performance, for example, in the case of a steel wire, when the outer diameter of the stranded wire and the outer diameter of the single wire are the same, the applied pressure and impact force on the surface to be processed are more in the single wire than in the stranded wire. For the absorption force and dispersion force against the reaction force such as impact force received by the brush piece from the work surface, the stranded wire is larger than the single wire, and the durability against breakage is also better for the stranded wire, The performance etc. which have durability higher than a single wire are mention | raise | lifted.

  In addition, after bundling a plurality of fibers, a bundling body formed by twisting, after bundling a plurality of bundles, using a brush piece formed to twist and form a twisted wire, The wheel brush can absorb and disperse a reaction force such as an impact force received by the brush piece from the work surface, and can have high durability against breakage and the like. Therefore, the brush piece does not break, and even when the brush piece is deformed, the processing performance is not deteriorated and high durability can be obtained.

  In addition, when bundling a plurality of single wires whose cross sections are formed in a polygon and then using a brush piece that is twisted to form a twisted wire, the wheel brush is a brush piece. Polygonal corners formed on a plurality of single wires that make up can be brought into contact with the surface to be processed so as to be scraped off, so that various processes such as high grinding, polishing, surface treatment, cleaning, and deburring are performed. I can do things.

  In addition, when a wheel brush having a brush piece formed in a truncated cone shape is selected, the brush piece has a tapered outer peripheral portion. The tip of the brush piece can be aligned very quickly and can be easily inserted. In addition, since the outer peripheral portion of the brush piece is tapered, the wheel brush is formed by gradually changing different rotation outer diameters. Therefore, different pressing force can be applied to the hole portion of the surface to be processed while gradually changing, so that processing can be performed. For this reason, it is not necessary to use wheel brushes such as rough finish, intermediate finish, and precision finish in order, and it is possible to process with a single wheel brush so that the rough work surface is in a precise state. it can. The above setting is suitable for polishing the surface to be processed, surface treatment, and deburring.

  In addition, when a wheel brush having a brush piece formed in a roughly corrugated shape is selected, for example, in the case where the work surface is a hole having a plurality of grooves, the roughly corrugated shape formed in the brush piece is , It can be processed by entering the groove. For this reason, it is possible to precisely polish the surface to be processed, to perform surface treatment, and to perform deburring without generating a processing residue in the groove.

  Further, when a wheel brush having a brush piece formed in a polygonal column shape is selected, for example, the corner of the surface to be machined can be contacted so as to scrape the corner of the brush piece, so that the processing remaining Will not occur. Moreover, since the brush piece has a polygonal column shape, the wheel brush can be prevented from rolling during storage.

  In addition, when a wheel brush having a brush piece formed in an approximately spherical shape is selected, for example, it is possible to accurately contact a concave spherical surface to be processed.

  (1) As another embodiment, when using a wheel brush in which brush pieces are radially formed on the outer peripheral portion of the core material and the shaft is penetrated and fixed to the core material, For example, by attaching to a power tool such as a hand drill or a machine tool such as a lathe, it can be used by being rotated at a predetermined rotational speed. Therefore, even when a large number of surfaces to be processed are formed continuously, various specifications such as optimum grinding, polishing, surface treatment, cleaning, deburring, etc. are set by setting specifications such as the number of rotations and rotation time. Can be processed.

  (2) The wheel brush is formed from a plurality of brush pieces having different rotation outer diameters. For this reason, the brush piece having a large rotation outer diameter is supported by the brush piece having a smaller rotation outer diameter. Therefore, the brush piece having a larger rotation outer diameter is supported at the root portion. Since the hair waist can be set stronger than the tip, the hair waist can be brought into strong contact with the surface to be processed. Further, the fall of the hair can be prevented or reinforced by the brush piece having a small rotating outer diameter. Therefore, the wheel brush can have high durability.

  In addition, when the stainless steel strand and the nylon single wire are used as the material of the brush piece of the wheel brush, after the flash is peeled off from the work surface with the stainless steel strand, the nylon single wire Then, by wiping off the surface to be processed, the flash can be peeled off from the surface to be processed, and the surface can be polished or smoothed. In the above, deburring can be performed more suitably by setting the rotational outer diameter of the nylon single wire to be larger than the rotational outer diameter of the stainless steel strand. In addition, even when a nylon strand with abrasive grains and a single nylon wire are used, the same effects as described above can be obtained. Also, when stainless steel strands and nylon single wires with abrasive grains are used, a relatively rough beam is peeled off from the surface to be processed with stainless steel strands, and then a single strand of nylon with abrasive grains. Only by this, the fine flash can be peeled off from the work surface. In addition, when a stranded wire of a piano wire and a single wire of stainless steel are used, the stranded wire of the piano wire reinforces the single wire of stainless steel, so that it is possible to prevent the hair from falling down or being broken. Also, when stainless steel single wire or stainless steel stranded wire is used, a relatively coarse beam is peeled off from the work surface with a stainless steel single wire, and then a fine wire is drawn with a stainless steel stranded wire. Can be peeled off from the work surface. In addition, when conductive fibers and stainless steel strands are used, the beams are peeled off from the surface to be processed with stainless steel strands, and the conductive fibers are applied to the surface to be processed or the wheel brush. The generated static electricity can be removed. Moreover, the material of a brush piece can set various materials other than the above according to the intended purpose.

  (2) As another embodiment, a wheel brush comprising a brush piece formed in a substantially triangular prism shape having a corner portion and a plane portion, and a brush piece having a rotation outer diameter different from that of the brush piece and having a plane portion. When the wheel brush is used, the wheel brush can bring the corner portion and the flat portion into contact with the surface to be processed. Therefore, for example, in the case of deburring the work surface, the deburring process is performed on the flat surface, and the flash peeled off from the work surface is scraped or wiped off at the corner, It can be removed outside the work surface.

  (3) The wheel brush is formed by untwisting the ends of the brush pieces within a predetermined length. For this reason, the brush piece is formed with a plurality of single wires having a substantially spiral shape formed by twisting in a predetermined length range, and therefore, the brush piece has a very high density with respect to the work surface and has a bristle. You can touch the supple single line of your waist. Therefore, even when a complicated uneven shape or a minute hole is formed on the surface to be processed, a plurality of pieces having a substantially spiral shape formed within a predetermined length range of the end of the brush piece. A single wire enters a complicated uneven shape or a minute hole, and can be processed quickly and accurately.

  (4) The wheel brush is formed by twisting a plurality of single wires having a cylindrical cross section. Therefore, the weight of the brush piece can be reduced, and the twisting of the single wire can be twisted with a small twisting force compared to the case of twisting the single wire of the cylindrical structure. Therefore, the price of the brush piece can be reduced. In addition, because the brush piece has innumerable twist marks formed on the outer periphery of the brush piece, the brush piece can bring the twist marks into contact with the surface to be processed, and the surface to be processed can be strongly scraped. it can. The brush piece can be suitably used for grinding, cleaning, surface treatment, and deburring of the work surface.

  (5) When using a brush piece that has been formed into a twisted wire shape after twisting a single wire with a coating layer formed on the outer periphery of the wheel brush, Since the layer can suppress or prevent the breakage and deterioration of the core wire, the brush piece has high durability even when high grinding, polishing and deburring ability is required for the work surface. Can have.

  Also, after bundling a plurality of single wires, twisting them to form a twisted wire, and then using a brush piece with a coating layer on the outer periphery of the plurality of single wires formed in a twisted wire shape In this case, the coating layer can suppress or prevent shape deformation or deterioration such as untwisting or untwisting of a plurality of single wires that are twisted to form a coating layer. Therefore, the brush piece can have high durability.

  When processing the surface to be processed, such as grinding, polishing, surface treatment, cleaning, deburring, etc., even when the processing conditions are inferior, the brush piece is not broken and the brush piece is deformed. However, in the wheel brush for performing various processes, the wheel brush has at least a core and a brush piece. It was formed, and the brush piece was realized in a configuration in which only the stranded wire or a stranded wire and a single wire was formed.

In FIG. 13, reference numeral 81 denotes a wheel brush.

  As shown in FIG. 1, the wheel brush 1 of the present invention is formed in a substantially cylindrical shape by a core material 2 and a brush piece 3. The brush pieces 3 are formed radially on the outer periphery of the core member 2. The core material 2 is formed of flanges 2A, 2B and 2C as shown in FIG.

The flange 2 </ b> C is formed in a substantially circular flat plate shape having a hole 50 at the center.

  Further, as shown in FIG. 2, the brush piece 3 is formed so as to be twisted by adding a twist after a plurality of single wires 4 are bundled. As the material of the single wire 4, a stainless steel wire represented by SUS304 or the like is used. In general, the brush piece 3 may be called a rope, a cable, a wire rope, or the like. Moreover, about the shape of the wire rope as one Example of the brush piece 3, it is described in JISG3540 as an operation wire rope, and the twist direction, the twisting method, a test, etc. which are described in the said JISG3540 are used. You can also do things. In addition to the above, the material of the single wire 4 is steel wires such as various piano wires and hard steel wires, non-ferrous metal wires such as brass wires and phosphor bronze wires, various carbon fiber wires, copper sulfide composite fiber wires, and silver composite wires. Any material can be used as long as it is a material that can be formed into a stranded wire shape, such as a fiber wire, synthetic fibers containing various abrasive grains such as alumina and silicon oxide.

  Next, a manufacturing procedure of the wheel brush 1 will be described with reference to FIGS. 11 and 12. First, as shown in FIG. 11, the approximate center portions of the plurality of brush pieces 3 are sandwiched between the hole portions 70 of the flange 2B. Next, after inserting the end portion 5 of the flange 2A into the hole portion 60 of the flange 2B, the hole portion 50 of the flange 2C is passed through the end portion 5 of the flange 2A. Next, it presses from the upper part of the edge part 5, and it crimps and fixes it by crushing the edge part 5. FIG. By the above procedure, the wheel brush 1 having a cross section as shown in FIG. 12 is formed.

  The wheel brush 1 of the present invention is mainly used for various processing such as grinding, polishing, surface treatment, cleaning, deburring and the like of a work surface. Grinding is a process of smoothing the surface of the work surface with a brush. Polishing is a process of polishing and smoothing the surface of the work surface with a brush. The surface treatment is a process for improving the state of the surface to be processed, such as curing, beautifying, smoothing, and corrosion resistance the surface of the surface to be processed. The cleaning is a process of cleaning the surface of the processing surface with a brush. Deburring is a process of removing an excess portion formed on the edge of a product by brushing with a brush.

  The material of the brush piece 3 may be natural fiber or chemical fiber according to the purpose of use if it is a material that can be used for various processing such as grinding, polishing, surface treatment, cleaning, and deburring. Can be set and used in a timely manner. Natural fibers are fibers made from plants, animals and minerals. Plant fibers include, for example, bast fibers such as ferns and palms, leaf fibers such as packing and sisal, fruit fibers such as palm, There are cotton, linen, asbestos. Animal fibers include, for example, pig hair, horse hair, and eyelash as hard hair, and goat hair, human hair, and eyelash as soft hair, and other types include wool and silk. The chemical fiber is a fiber made by chemical synthesis or processing from petroleum, coal, or the like, and includes synthetic fiber, fiber with abrasive material, conductive composite fiber, inorganic fiber, recycled fiber, and semi-synthetic fiber. Synthetic fibers are fibers spun from a synthetic polymer compound, and include synthetic fibers such as fluorine-based, polyamide-based, polyvinyl chloride-based, polypropylene-based, polyethylene-based, and aramid-based fibers. Abraded fibers include, for example, materials having grinding performance such as silicon carbide, alumina, diamond, and other minerals, silica, ceramics, and the like, which are adhered, kneaded, or mixed with fibers of a base material such as nylon or PBT. It is a fiber formed. The conductive composite fiber is a fiber having a performance capable of passing an electric current, and includes various carbon fibers, copper sulfide composite fibers, and silver composite fibers. The conductive composite fiber is sometimes referred to as a conductive fiber. The inorganic fiber is a fiber made of an inorganic compound, and examples thereof include various steel wires such as a piano wire, a hard steel wire, a stainless steel wire, and an oil temper wire, and a non-ferrous metal wire such as a brass wire and a phosphor bronze wire. Recycled fiber is a fiber made by melting wood, cotton, hemp, etc. made of natural cellulose, such as rayon. Semi-synthetic fiber is an intermediate between synthetic fiber and regenerated fiber. It is a fiber made by chemically treating natural polymeric substances such as cellulose to form esters, etc., and acetate fiber. Etc.

  Next, a comparative durability test using a stranded wire and a single wire will be described. First, the thing of the same specification as said comparative grinding test was used for the strand wire and the single wire. Next, after manufacturing three wheel brushes each having a brush outer diameter of 100 mm with the above-described stranded wire and single wire, a cylindrical test piece having an inner diameter of 98 mm installed on a drilling machine is rotated at 600 rpm every 5 seconds. The wheel brush was repeatedly inserted into and removed from the test piece, and the presence or absence of hair loss after 1 minute, 3 minutes, 10 minutes, 30 minutes, and 1 hour was confirmed. As a result, in the stranded wire, only one of the produced three wheel brushes had hair loss after 1 hour. Further, all three single wires had hair loss after 3 minutes. From the above results, it was found that the stranded wire is less prone to hair loss than the single wire, can be ground for a longer time than the single wire, and has high durability performance.

  Since the wheel brush 1 according to the first embodiment is configured as described above, the wheel brush brush 1 is configured so that the brush pieces 3 are twisted and then twisted after a plurality of single wires 4 are bundled. It is formed. For this reason, the wheel brush 1 can absorb and disperse the reaction force such as the impact force received by the brush piece 3 from the surface to be processed by the stranded wire 4. Therefore, the brush piece 3 can be prevented from being broken, and even when the brush piece 3 is deformed, the processing performance is not deteriorated. Moreover, since the hair breakage and deterioration can be prevented, the wheel brush 1 having extremely high durability can be manufactured.

  In addition, since the brush piece 3 is formed of a stranded wire, the brush piece 3 can generate fluff due to the plurality of single wires 4 being twisted. Therefore, the brush piece 3 is difficult to get a hair ridge and can prevent hair breakage. Moreover, since it is hard to have a fuzz, even when the wheel brush 1 is used for a long time, the outer diameter of the brush piece 3 before use can be hold | maintained. Therefore, the wheel brush 1 can have high durability. Further, since the tip of the stranded wire contacts the surface to be processed, the brush piece 3 may be in a state where the twist of the tip is slightly loosened at the time of contact. Therefore, for example, in the deburring process, the deburring can be performed uniformly at any position on the processing surface.

  Furthermore, since the brush piece 3 is formed in a stranded wire shape, the wheel brush 1 is formed in a stranded wire shape using, for example, an ultrafine fiber having a diameter of 0.1 mm or less as the single wire 4. Depending on the purpose of use, the state of formation of the brush piece 3 can be set and used optimally. When a stranded wire made of ultrafine fibers having a diameter of 0.1 mm or less is used for the single wire 4, it can be optimally used for deburring of a work surface on which extremely fine flash is formed.

  Further, the wheel brush 1 is formed of a core material 2 and a brush piece 3, and after sandwiching the approximate center part of the plurality of brush pieces 3 into the hole part 70 of the flange 2B, the end part 5 of the flange 2A is inserted. , By inserting into the hole 60 of the flange 2B, passing the hole 50 of the flange 2C through the end 5 of the flange 2A, pressurizing from above the end 5 and crushing the end 5; Since it is formed by caulking and fixing, the brush pieces 3 can be formed by being densely packed radially around the axis of the core material 2. Therefore, even if the processing surface is difficult to process compared to a flat surface, such as a cylindrical inner surface, a micro hole, or the inner part of a tube, various processing such as grinding, polishing, surface treatment, cleaning, deburring, etc. Can be implemented optimally. Further, the structure and the manufacturing procedure can be simplified as compared with a flocking method such as flat line flocking or round line flocking. Further, since the brush piece 3 made of a stranded wire is sandwiched in the hole portion 70 of the flange 2B and is radially formed around the axis of the core material 2, the wheel brush 1 is sandwiched between the brush pieces 3 which are sandwiched. The concavo-convex shape of the surface of the stranded wire formed on the side surface of the substantially central portion of the flange 2A and 2C is bitten. Therefore, it is possible to manufacture a wheel brush 1 that is more difficult to remove hair than a single wire.

  In addition, when the brush piece 3 is brought into contact with the surface to be processed, the wheel brush 1 loosens the twist of the tip of the brush piece 3 contacting the surface to be processed by a predetermined dimension, and the brush piece 3 is separated from the surface to be processed. The material of the single wire 4 which comprises the brush piece 3, detailed shape, the twist conditions of the brush piece 3, etc. can be set so that twist may return when it leaves | separates. In the case of the setting as described above, the tip portion of the brush piece 3 loosely twisted is divided into a plurality of single wires 4. Therefore, the divided single wires 4 come into contact with the surface to be processed, and enter the extremely fine uneven shape, the deep part, or the fine holes of the surface to be processed, for example, processing such as deburring. It can be carried out optimally without leaving any processing. Further, since the twist returns when the brush piece 3 is separated from the surface to be processed, the tip portion can always be brought into contact under the same conditions. Therefore, the wheel brush 1 can have extremely high durability.

  In addition, when the brush piece 3 is brought into contact with the surface to be processed, the wheel brush 1 gradually changes in the twist of the tip portion of the brush piece 3 with time to contact the surface to be processed. The material of the single wire 4 constituting the brush piece 3, the detailed shape, the twisting condition of the brush piece 3, etc. can be set. In the case where the setting is made as described above, the tip of the brush piece 3 gradually progresses as the loosening of the twist progresses with the time of contact with the surface to be processed, so that the processing time increases. Thus, the tip of the brush piece 3 gradually changes and comes into fine contact with the surface to be processed. Therefore, even if the surface to be processed is rough, it is not necessary to use wheel brushes for rough finishing, intermediate finishing, precision finishing, etc. in order, and one wheel brush 1 can be used to form a rough surface to be processed. It can be processed to a precise state. The above setting is suitable for polishing the surface to be processed, surface treatment, and deburring.

  Moreover, the wheel brush 1 can be used by loosening the twist of the outer tip of the brush piece 3 by a predetermined dimension. As described above, when untwisted and used, a brush portion having a generally spiral shape formed by twisting is formed at the outer front end portion of the brush piece 3, so that it is extremely dense with respect to the work surface. It is possible to bring the brush piece 3 having a high degree of flexibility and flexibility into contact. Therefore, even when a complicated uneven shape or a minute hole is formed on the surface to be processed, the brush portion having a substantially spiral shape formed at the outer front end portion of the brush piece 3 has a complicated uneven shape. Alternatively, it can be processed quickly and accurately by entering a minute hole. The above setting is suitable for polishing, cleaning, surface treatment, and deburring of the work surface.

  Moreover, since the brush piece 3 is radially formed around the axis of the substantially cylindrical core material 2, the wheel brush 1 can be rotated at high speed and brought into contact with the surface to be processed. Therefore, even when the area of the work surface is very large, polishing, cleaning, surface treatment, or deburring of the work surface can be performed quickly and accurately.

  Further, a predetermined number of wheel brushes 1 can be laminated according to the purpose of use. Therefore, the number of wheel brushes 1 to be laminated can be set at an appropriate time so that optimum processing can be performed even when the processing width of the processing surface is wider than the thickness of the wheel brush 1. Therefore, even when the width of the work surface is wide, polishing, cleaning, surface treatment, or deburring of the work surface can be performed quickly and accurately.

  Although the wheel brush 1 of Example 1 has the above-described configuration, the cross-sectional shape formed on the plurality of single wires 4 constituting the brush piece 3 is not limited to the round shape described above, but is a triangle. Polygonal shapes such as quadrangular, pentagonal, hexagonal, etc., or various irregular cross-sectional shapes such as approximate waveform, ellipse, approximate V-shape, approximate X-shape, approximate Y-shape, etc. can be employed. In the case of employing the above, since the corners of various irregular cross-sections formed on the single wire 4 can be brought into contact with the surface to be processed so as to be scraped, there is no processing residue and high grinding. Deburring process can be performed quickly and accurately.

  Moreover, about the structure of the several single wire 4 which comprises the brush piece 3, a substantially cylindrical shape and various square tube shapes can be employ | adopted besides a columnar structure. When a generally cylindrical shape or various square tube shapes are used, the brush piece 3 can be reduced in weight, and the twisting of the single wire 4 can be easily processed with less twisting force than the cylindrical structure. 3 price can be reduced. In addition, since the single wire 4 having a substantially cylindrical shape and various rectangular tube shapes is hollow, stress from the side surface direction generated during twisting is applied and the wire is crushed. Therefore, a fine uneven-shaped twist mark is formed on the surface portion. Therefore, the brush piece 3 can bring a fine uneven twist mark into contact with the surface to be processed, and can strongly scrape the surface to be processed. The above setting is suitable for grinding, cleaning, surface treatment, and deburring of the work surface.

  The brush piece 3 can also be used by forming a single wire of a plurality of types of materials into a stranded wire after mixing. Moreover, the brush piece 3 can also be used, after producing a plurality of types of stranded wires formed of the same type of single wire and then mixing a plurality of types of stranded wires.

  In addition to the configuration as described above, the configuration of the core material 2 is such that the brush piece 3 can be formed radially around the axis of the core material 2, for example, using a core wire instead of the flange 2 </ b> B. Any configuration can be used, if any. In the case where the core wire is used, the wheel brush 1 is sandwiched between the flanges 2C after the substantially central portion of the plurality of brush pieces 3 is sandwiched between the core wires and then wound around the outer peripheral surface of the substantially cylindrical shape of the flange 2A. It can be manufactured by press-fitting from the upper part of the end portion 5 of the flange 2A and crushing the end portion 5 to fix it.

  Further, the material of the core material 2 is also optimized, for example, various steel materials, non-ferrous metal materials, synthetic resin materials, natural fiber materials such as bamboo, wood and paper, various rubber materials, etc. Can be set in a timely manner.

  In addition, an uneven shape can be formed on the upper surfaces of the flanges 2A, 2B, and 2C in contact with the brush piece 3. In the case of adopting the above method, the upper surfaces of the flanges 2A, 2B, 2C constituting the core material 2 can come into contact with the brush piece 3 so as to be engaged with each other. The holding force can be strengthened, and the brush piece 3 can be prevented from falling off.

  Furthermore, the wheel brush 1 can sandwich the flanges 2A and 2C after a predetermined number of the flanges 2B sandwiching the brush pieces 3 are stacked. In the case of adopting the above method, the thickness of the brush piece 3 formed on the side surface of the wheel brush 1 can be set thicker according to the purpose of use. Therefore, even when the width of the work surface is wide, polishing, cleaning, surface treatment, or deburring of the work surface can be performed quickly and accurately.

  Next, a wheel brush according to another embodiment of Example 1 will be described. As shown in FIG. 3, the wheel brush 11 of another embodiment is formed in a substantially cylindrical shape with a core material 2, a brush piece 3, and a brush piece 13. The brush pieces 3 and the brush pieces 13 are formed radially on the outer peripheral portion of the core member 2. The brush piece 3 is a stranded wire, and the brush piece 13 is a single wire as shown in FIG. The material of the brush piece 3 and the brush piece 13 can be set timely according to the purpose of use. For example, stainless steel strands and nylon single wires are suitable for purposes of deburring. When stainless steel strands and nylon single wires are used, use a stainless steel strand to peel off the flash from the work surface, and then wipe the work surface with a single nylon wire. Surface treatment can be smoothed. Also suitable are stainless steel strands, nylon single wires with abrasive grains, and the like. When using stainless steel stranded wire and single nylon wire with abrasive grains, use a stainless steel stranded wire to peel off the relatively rough beam from the work surface, and then use a single wire with nylon abrasive grains. Fine burr can be peeled off from the work surface.

  Further, as shown in FIG. 4 (B), a plurality of converging bodies 7 formed by bundling a plurality of fibers and then bundling are formed, and then bundling and then twisting to form a twisted wire. A certain brush piece 23 can also be used. Further, as shown in FIG. 4C, after a plurality of single wires 14 whose cross sections are formed in a polygon having a quadrangular shape are bundled, a brush piece is formed so as to be twisted by twisting. 33 can also be used.

  Further, as shown in FIGS. 5A to 5D, for example, when the formation state of the brush piece is set to a truncated cone shape, an approximate waveform shape, a polygonal column shape, or an approximate spherical shape, Since the optimum shape can be selected and processed according to the shape, various types of processing can be performed quickly and accurately. When the wheel brush 21 having the brush piece 43 formed in a truncated cone shape is selected as shown in (A), the brush piece 43 has a tapered outer peripheral portion. The wheel brush 21 can very quickly align the tip of the brush piece 43 with respect to the hole, and can be easily inserted. Further, since the outer peripheral portion of the brush piece 43 is tapered, the wheel brush 21 is formed by gradually changing the different rotation outer diameter. Therefore, different pressing force can be applied to the hole portion of the surface to be processed while gradually changing, so that processing can be performed. Therefore, it is not necessary to use wheel brushes such as rough finish, intermediate finish, and precision finish in order, and processing is performed with one wheel brush 21 so that the rough workpiece surface is in a precise state. Can do. The above setting is suitable for polishing the surface to be processed, surface treatment, and deburring. In addition, when the wheel brush 31 having the brush piece 53 formed in a substantially waveform shape is selected as shown in (B), for example, even when the work surface is a hole having a plurality of groove portions, the brush piece. The substantially waveform shape formed in 53 can enter the groove and be processed. For this reason, it is possible to precisely polish the surface to be processed, to perform surface treatment, and to perform deburring without generating a processing residue in the groove. Further, when the wheel brush 41 having the brush piece 63 formed in a polygonal column shape is selected as shown in (C), for example, the corner of the brush piece 63 is scraped out from the corner of the surface to be processed. Since it can be contacted, there is no processing residue. Further, since the brush piece 63 has a polygonal column shape, the wheel brush 41 can be prevented from rolling during storage. Moreover, when the wheel brush 51 which has the brush piece 73 formed in the substantially spherical shape is selected as shown in (D), for example, it is possible to accurately contact the concave spherical surface.

  Since the wheel brush according to another embodiment of Example 1 has the above-described configuration, the wheel brush 11 is composed of a stranded wire brush piece 3 and a single wire brush piece 13, and the outer periphery of the core material 2. It is formed radially on the part. Therefore, the wheel brush 11 can make the strand wire brush piece 3 and the single wire brush piece 13 contact the surface to be processed. Therefore, when processing the surface to be processed, such as grinding, polishing, surface treatment, cleaning, deburring, etc., even if the surface to be processed has various different processing conditions, the stranded wire having different processing performance Therefore, the wheel brush 11 can have optimum grinding, polishing, surface treatment, cleaning, and deburring performance according to the purpose of use. . As the different processing performance, for example, in the case of a steel wire, when the outer diameter of the stranded wire and the outer diameter of the single wire are the same, the applied pressure and impact force on the surface to be processed are more in the single wire than in the stranded wire. For the absorption force and dispersion force against the reaction force such as impact force received by the brush piece from the work surface, the stranded wire is larger than the single wire, and the durability against breakage is also better for the stranded wire, The performance etc. which have durability higher than a single wire are mention | raise | lifted.

  In addition, when a plurality of bundling bodies 7 formed by bundling a plurality of fibers and bundling a plurality of bundling bodies 7 and then twisting and then forming a twisted wire shape are used. The wheel brush 11 can absorb and disperse the reaction force such as the impact force received by the brush piece 23 from the work surface, and can have high durability against breakage and the like. For this reason, the brush piece 23 does not break, and even when the brush piece 23 is deformed, the processing performance is not deteriorated and high durability can be obtained.

  In addition, when a plurality of single wires 14 having a polygonal cross section are bundled, and then a brush piece 33 formed so as to be twisted by twisting is used, the wheel brush 11 is used. Since the polygonal corners formed on the plurality of single wires 14 constituting the brush piece 33 can be brought into contact with the surface to be machined, high grinding, polishing, surface treatment, cleaning, deburring Various processing such as can be performed.

  The wheel brush according to another embodiment of Example 1 has the above-described configuration, but the cross-sectional shape formed on the plurality of single wires 14 constituting the brush piece 33 is other than the above-described square shape. Also, shapes such as polygons such as triangles, pentagons, hexagons, and various irregular cross sections can be adopted.

  Next, a wheel brush according to another embodiment of Example 1 will be described. A wheel brush 81 according to another embodiment is formed of a core material 2, a brush piece 3, and a shaft 2D as shown in FIG. The brush pieces 3 are radially formed on the outer peripheral portion of the core material 2, and the shaft 2 </ b> D is penetrated and fixed to the core material 2. The brush piece 3 is a stranded wire.

  Since the wheel brush according to another embodiment of Example 1 has the above-described configuration, the wheel brush 81 is fixed to the core material 2 through the shaft 2D. For this reason, the shaft 2D can be used by being rotated at a predetermined rotational speed by attaching it to a power tool such as a hand drill or a machine tool such as a lathe. Therefore, even when a large number of surfaces to be processed are formed continuously, various specifications such as optimum grinding, polishing, surface treatment, cleaning, deburring, etc. are set by setting specifications such as the number of rotations and rotation time. Can be processed.

  Example 2 is shown in FIG. 6 and FIG. FIG. 6 is a perspective view of the wheel brush of the present invention as seen from the front side. In FIG. 6, 2 is a core material, 6 and 16 are rotating outer diameters, 61 is a wheel brush, and 83 and 93 are brush pieces. FIG. 7 is a side view of a wheel brush according to another embodiment. In FIG. 7, 8 is a corner | angular part, 9 and 19 are brush pieces, 18 is a plane part, 26 and 36 are rotation outer diameters, 71 is a wheel brush.

  The wheel brush 61 of the present invention is formed of the core material 2 and brush pieces 83 and 93 as shown in FIG. The brush pieces 83 and 93 are each sandwiched between the core material 2 and a predetermined number of them according to the purpose of use, and are formed radially around the core material 2. The brush pieces 83 and 93 are made of the same material or different materials. Further, the rotating outer diameter 16 of the brush piece 83 is formed so as to be larger than the rotating outer diameter 6 of the brush piece 93. Moreover, about the formation state of the brush pieces 83 and 93, only a stranded wire or a stranded wire and a single wire can be selected and used. The rotation outer diameters 6 and 16 indicate the heights of the respective brush pieces 93 and 83 when the wheel brush 61 is rotated. Further, as described above, since the brush pieces 83 and 93 have different rotational outer diameters, a step is formed between the tip portions of the brush pieces 83 and 93.

  Moreover, the material of the brush piece 83 and the brush piece 93 can be set timely according to the purpose of use. For example, for deburring purposes, stainless steel strands and nylon single wire combinations, abrasive nylon strands and nylon single wire combinations, stainless steel strands and abrasive strands Nylon single wire combination, piano wire stranded wire and stainless steel single wire combination, stainless steel stranded wire and stainless steel single wire combination, conductive fiber and stainless steel stranded wire combination etc. are suitable is there.

  When stainless steel strands and nylon single wires are used, after removing the beam from the work surface with stainless steel strands, wipe the work surface with a single nylon wire. The burr can be peeled from the surface to be processed and polished or smoothed by surface treatment. In the above, deburring can be performed more suitably by setting the rotational outer diameter of the nylon single wire to be larger than the rotational outer diameter of the stainless steel strand. In addition, even when a nylon strand with abrasive grains and a single nylon wire are used, the same effects as described above can be obtained. Also, when stainless steel strands and nylon single wires with abrasive grains are used, a relatively rough beam is peeled off from the surface to be processed with stainless steel strands, and then a single strand of nylon with abrasive grains. Only by this, the fine flash can be peeled off from the work surface. In addition, when a stranded wire of a piano wire and a single wire of stainless steel are used, the stranded wire of the piano wire reinforces the single wire of stainless steel, so that it is possible to prevent the hair from falling down or being broken. Also, when stainless steel single wire or stainless steel stranded wire is used, a relatively coarse beam is peeled off from the work surface with a stainless steel single wire, and then a fine wire is drawn with a stainless steel stranded wire. Can be peeled off from the work surface. In addition, when conductive fibers and stainless steel strands are used, the beams are peeled off from the surface to be processed with stainless steel strands, and the conductive fibers are applied to the surface to be processed or the wheel brush. The generated static electricity can be removed. Moreover, the material of the brush pieces 83 and 93 can set various materials other than the above according to the intended purpose.

  Since the wheel brush 61 according to the second embodiment is configured as described above, the brush piece 93 is formed so that the rotating outer diameter is smaller than the brush piece 83. Therefore, since the root part of the brush piece 83 is supported by the brush piece 93, the bristle waist of the root part is set stronger than the tip part. Therefore, the brush piece 83 can make a bristle waist strongly contact with a to-be-processed surface. Further, the brush piece 83 can prevent or reinforce hair fall by the brush piece 93. Therefore, the wheel brush 61 can have high durability.

  Although the wheel brush 61 of the second embodiment has the above-described configuration, a plurality of brush pieces constituting the wheel brush 61 can be selected and used in a timely manner other than the above two types.

  Next, a wheel brush according to another embodiment of Example 2 will be described. As shown in FIG. 7, the wheel brush 71 according to another embodiment has a rotating outer diameter 26, a brush piece 9 formed in a substantially triangular prism shape including a corner portion 8 and a planar portion 18, and the planar portion 18. And a brush piece 19 having a rotating outer diameter 36 is formed.

  Since the wheel brush 71 according to another embodiment of Example 2 is configured as described above, the wheel brush 71 can bring the corner portion 8 and the flat portion 18 into contact with the surface to be processed. . Therefore, for example, in the case of deburring the surface to be processed, the surface portion 18 is deburred, and the flash peeled off from the surface to be processed is scraped or wiped off at the corner portion 8. Thus, it can be removed outside the surface to be processed.

  Example 3 is shown in FIG. FIG. 8 is a front view of a brush piece used in the wheel brush of the present invention. In FIG. 8, 10 is a length, 24 is a single wire, 28 is an end, and 29 is a brush piece.

  As shown in FIG. 8, the brush piece 29 is formed so that a plurality of single wires 24 are bundled and then twisted to form a twisted wire shape. Further, the end portion 28 is formed in a predetermined length 10 range by untwisting the twist.

  The wheel brush of the third embodiment uses the brush piece 29 as described above, and the brush piece 29 is formed by untwisting the end portion 28 within a predetermined length 10 range. In addition, a plurality of single wires 24 having a substantially spiral shape formed by twisting are formed in the range of the predetermined length 10. For this reason, since the single wire 24 that is extremely dense and flexible can be brought into contact with the surface to be processed, complicated uneven shapes or minute holes are formed on the surface to be processed. Even in the case, a plurality of single wires 24 having a substantially spiral shape formed in the range of the predetermined length 10 of the end portion 28 of the brush piece 29 enter a complicated uneven shape or a minute hole portion, and quickly. It can be processed accurately and accurately.

  Example 4 is shown in FIG. FIG. 9 is a side view of a brush piece used in the wheel brush of the present invention and an enlarged perspective view as seen from the front side. (A) and (B) are side views, and (C) and (D) are FIG. In FIG. 9, 20 is a twist mark, 34, 44, 54 and 64 are single wires, and 39, 49 and 59 are brush pieces.

  The brush piece 39 is formed so as to form a twisted wire shape by bundling seven single wires 34 made of a quadrilateral whose cross section is a kind of polygon, and then twisting. Further, the brush piece 49 is made into a stranded wire shape by bringing the five single wires 54 having a triangular cross section into contact with the outer peripheral portion of the single wire 44 having a pentagonal cross section and bundling six, and then twisting them. It is formed as follows. Further, the brush piece 59 is formed so as to be twisted by twisting seven single wires 64 having a cylindrical shape whose cross section is a kind of cylindrical shape. In addition, innumerable twist marks 20 having substantially concave and convex shapes formed by twisting are formed on the outer peripheral portion of the brush piece 59.

  As Example 4, a brush piece 39 in which a plurality of single wires 34 having a polygonal cross section are formed in a twisted wire shape on a wheel brush, or a plurality of single wires 44 and 54 having a polygonal cross section in a twisted wire shape. In the case where the brush piece 49 formed in the above is used, the corners of the polygonal cross section formed on the single wires 34 and 54 can be brought into contact with the surface to be processed so as to be engaged with each other. Can be processed variously by scraping it firmly. The brush pieces 39 and 49 can be suitably used for grinding, surface treatment, and deburring of the work surface.

  Further, as Example 4, in the case where the brush piece 59 in which a plurality of single wires 64 having a cylindrical cross section is formed in a twisted wire shape is used for the wheel brush, the brush piece 59 can be reduced in weight and the single wire Since the twisting process of 64 can be twisted with a small twisting force compared to the case of twisting a single wire having a cylindrical structure, the price of the brush piece 59 can be reduced. In addition, since the innumerable twist marks 20 are formed on the outer periphery of the brush piece 59, the brush piece 59 can bring the twist marks 20 into contact with the surface to be processed. Can be scraped. The brush piece 59 can be suitably used for grinding, cleaning, surface treatment, and deburring of a work surface.

  Example 5 is shown in FIG. FIG. 10 is a perspective view of a brush piece used in the wheel brush of the present invention as seen from the front side. In FIG. 10, 4 is a single wire, 30 and 40 are coating layers, and 69 and 79 are brush pieces.

  The brush piece 69 shown in FIG. 10A is formed so that a plurality of single wires 4 are bundled and then twisted to form a stranded wire shape. The single wire 4 has a coating layer 30 formed on the outer periphery. Moreover, as a method of forming the coating layer 30, various film processing, adhesion processing, plating processing, electrostatic flocking processing and the like can be set as appropriate according to the purpose of use. Further, the brush piece 79 shown in FIG. 10B is formed by bundling a plurality of single wires 4 and then twisting them to form a twisted wire, and then forming a plurality of single wires formed in a twisted wire shape. A coating layer 40 is formed on the outer periphery of 4.

  As Example 5, a brush piece 69 formed to be twisted by twisting a plurality of single wires 4 each having a coating layer 30 formed on the outer periphery of the wheel brush was used. In some cases, since the coating layer 30 can suppress or prevent the breakage and deterioration of the core wire 4, even if a high grinding, polishing, and deburring capability is required for the work surface, the brush The piece 69 can have high durability.

  As Example 5, after bundling a plurality of single wires 4 to a wheel brush, twisting to form a stranded wire, and then coating the outer periphery of the plurality of single wires 4 formed into a stranded wire In the case where the brush piece 79 formed with 40 is used, the coating layer 40 is twisted and deformed, such as untwisting and untwisting of a plurality of single wires 4 formed in a twisted wire shape. Deterioration can be suppressed or prevented. Therefore, the brush piece 79 can have high durability.
