Description

  The present invention relates to a liquid jet machining method for machining a workpiece by jetting a high-pressure liquid, and a receptacle for collecting scattered matter generated during the machining.

  Since large structures such as aircraft main wings have different stresses depending on the location, so-called composite materials in which the material is changed depending on the location are often used. And, when processing a structure made of such a composite material into a desired shape, when processing using a laser cutting machine with a uniform temperature regardless of location, the material with a low heat-resistant temperature is thermally deformed, Processing accuracy may be reduced. Therefore, in order to prevent such a problem, when processing a large structure, a liquid jet processing method using an abrasive water jet processing machine (hereinafter referred to as “AWJ processing machine”) is widely adopted. Yes. The AWJ processing machine used in this liquid jet processing method processes a workpiece by jetting high-pressure water mixed with an abrasive, and has an advantage that the influence of heat on the material is small.

  In such an AWJ machine, since the sprayed water and the cut workpiece are scattered around, it is necessary to collect the scattered matter. Conventional AWJ machines are roughly divided into so-called water tank systems and point catcher systems depending on the difference in the scattered matter collection system.

  Here, the water tank method is a method in which a workpiece is placed on a water tank of the same size or larger than that and water is injected into the workpiece in a state where water is stored in the water tank. It is a method. According to this method, since the processing operation is performed on the water tank, the generated scattered matter can be collected by the water tank covering the workpiece, and the parts other than the processing target part are not damaged.

  On the other hand, with the point catcher method, a nozzle that injects water and a catcher that collects scattered objects are integrated, and the nozzle moves on one side across the workpiece, and the catcher follows the other side. Thus, the scattered matter is collected while moving (see, for example, Patent Document 1). According to this method, the catcher that moves following the nozzle need only be large enough to cover only the periphery of the processing position of the workpiece, and the entire apparatus of the AWJ processing machine can be miniaturized.

Japanese Patent Laid-Open No. 62-80000

  However, according to the liquid jet processing method using the conventional AWJ processing machine, the following problems exist depending on the scattered matter collection method. First, in an AWJ processing machine that employs a water tank system, a water tank having a size that covers the entire workpiece is required. Therefore, if the workpiece is a large structure, a huge water tank is required. Therefore, the manufacturing cost of the water tank itself increases and the cost of water stored in the water tank also increases. Further, there is a problem that it is necessary to process a large amount of water collected by a water tank and mixed with scattered matter.

  On the other hand, in the AWJ processing machine that employs the point catcher method, there is a problem that the accessibility to the processing position is poor when the workpiece is a large structure having several tens of meters on all sides. In other words, the point catcher type AWJ machine has a nozzle and a catcher that are integrated, so when machining the center of a large structure, the nozzle is placed on one side of the workpiece and the other In order to arrange the catchers on the sides, it is necessary to make a hole for allowing the nozzle or the catcher to pass in the vicinity of the machining position in the workpiece. Accordingly, the work is complicated because the drilling work is required prior to the machining work.

  The present invention has been made in consideration of such circumstances, and the object thereof is to provide good accessibility to the machining position even if the workpiece is a large structure, and to be scattered. An object of the present invention is to provide an AWJ processing machine and a liquid jet processing method using the AWJ processing machine in which a receiving tool for collecting objects does not become large.

  In order to achieve the above object, the present invention employs the following means. That is, in the liquid jet machining method according to the present invention, a liquid ejector capable of jetting high-pressure liquid is disposed on one side across the workpiece, and scattered objects are disposed on the other side across the workpiece. Drilling is performed while drilling the workpiece by disposing a receiving device close to the workpiece and ejecting high-pressure liquid from the liquid ejector toward the machining position of the workpiece. A first step of collecting the scattered matter generated during processing with the support; and an end face processing machine capable of performing end face processing on one side of the work, with the support being separated from the work to be processed. End face processing while arranging a collecting tool capable of accommodating scattered matter in a gap formed between the receiving tool and the workpiece, and processing the workpiece with the end face processing machine. The second construction to collect the scattered matter that sometimes occurs with the collection tool Characterized in that it comprises a and.

According to such a method, the worker places the receiving tool close to the workpiece before starting the first step. Thereby, the high-pressure liquid ejected from the liquid ejector disposed on the opposite side of the receiver with the workpiece interposed therebetween, and a part of the workpiece cut by the high-pressure liquid can be collected by the receiver. .
Further, after the end of the first step and before the start of the second step, the operator separates the receiving tool from the workpiece and collects it in the gap generated between the processing member and the receiving tool. Arrange the tools. Thereby, the scattered material generated when the end surface processing is performed by the end surface processing machine disposed on the opposite side of the recovery tool with the workpiece interposed therebetween can be recovered by the recovery tool. Therefore, the receiving tool and the collecting tool do not need to be large enough to cover the entire workpiece, and are sufficient to cover only the vicinity of the machining position on the workpiece. Further, when the operator needs to perform the second step, the end surface processing is performed with the workpiece sandwiched between the holes formed in the first step after the completion of the first step. The collection tool can be arranged at a position opposite to the machine. Therefore, before performing the second step, it is necessary to separately form a hole different from the hole formed in the first step in order to place the recovery tool at a position opposite to the end face processing machine with the workpiece interposed therebetween. There is no.

  Further, in the liquid jet machining method according to the present invention, the receiving tool can place the collecting tool in a gap between the receiving member and the workpiece from the first state in the vicinity of the workpiece. The second state is deformable, and the first step is the first state, and the second step is the second state.

  According to such a method, it is possible to easily and reliably change from the first state in the vicinity of the workpiece to the second state in which the collection tool can be disposed between the workpiece by deforming the receiving tool. Can be changed.

  The receptacle used in the liquid jet machining method according to the present invention is disposed in the vicinity of the workpiece, and a liquid ejector disposed on the opposite side across the workpiece ejects high-pressure liquid. From the first state where the scattered matter generated when the workpiece is perforated is collected, the workpiece is arranged away from the workpiece, and the workpiece is sandwiched in the gap between the workpiece and the reverse. The end face processing machine arranged on the side can be deformed to a second state in which a collecting tool for collecting scattered matter generated when the work piece is end face processed is arranged.

  According to such a configuration, in the step of perforating the workpiece by the liquid ejector, the receiving device is placed in the first state, so that the high pressure liquid ejected from the liquid ejector or the high pressure liquid is cut. A part of the processed object can be collected by the receiving tool. Further, in the step of processing the end surface of the workpiece with the end surface processing machine, the scattered material generated during the end surface processing can be recovered by the recovery tool by setting the receiving tool in the second state.

  Further, the receptacle used in the liquid jet processing method according to the present invention is provided so as to be slidable along the side wall of the container member, which is a casing having an upper opening, and against the workpiece. A side wall extending member that is close to or away from each other, wherein the first state is a state in which the side wall extending member is in proximity to the workpiece, and the second state is a state in which the side wall extending member is It is in a state of being separated from the workpiece.

  According to such a configuration, the receiving tool can be deformed from the first state to the second state by a simple operation of sliding the side wall extending member along the side wall of the container member.

  The receptacle used in the liquid jet machining method according to the present invention is provided so as to be movable along the workpiece.

  According to such a configuration, when there are a plurality of processing positions on the workpiece, the receiving tool can be shared by sequentially moving the receiving tool from one processing position to another processing position. . Thereby, compared with the case where a receiving tool is installed separately for every processing position, the cost reduction by material cost reduction can be aimed at.

  The receptacle used in the liquid jet processing method according to the present invention is characterized in that the opening width of the container member can be adjusted.

  According to such a configuration, even when the shape of the surrounding space is different for each processing position in the workpiece due to a difference in the arrangement position of the member that supports the workpiece from below, the opening width of the container member By appropriately adjusting, the receiving tool can be disposed in the vicinity of an arbitrary processing position.

  The receptacle used in the liquid jet processing method according to the present invention is characterized in that the container member is rotatable about an axis parallel to the sliding direction of the side wall extending member.

  According to such a configuration, the side wall extension member can be moved in the sliding direction even when the shape of the neighboring space is different for each processing position on the workpiece due to a difference in the arrangement position of the member that supports the workpiece. The holder can be disposed in the vicinity of an arbitrary processing position by appropriately rotating about an axis parallel to the center.

According to the liquid jet machining method according to the present invention, the receiving tool and the recovery tool need only be large enough to cover only the vicinity of the processing position on the workpiece. Compared with the case of covering, it is possible to reduce the size of the receiver and the recovery tool and reduce the manufacturing cost thereof, and also to reduce the cost of water stored in the receiver and the recovery tool.
Further, when the operator needs to perform the second step, the end surface processing is performed with the workpiece sandwiched between the holes formed in the first step after the completion of the first step. The collection tool can be arranged at a position opposite to the machine. Therefore, compared with the case where a hole for allowing the collection tool to pass through the workpiece is formed in advance, the AWJ machine comprising the end face processing machine and the collection tool has good accessibility to the machining position, Work can be simplified.

The four side walls 122 are for the purpose of preventing water and abrasives from splashing around as well as the side walls 122 of the container main body 110. However, it is made of a relatively soft member such as aluminum or acrylic. In addition, you may comprise these four side walls 122 from the member excellent in abrasion resistance.
In addition, if the extension member main body 120 is a size which can accommodate the container main body 110 inside, the shape, material, etc. are not limited to this embodiment, and a design change is possible suitably.

As shown in FIG. 1, the two pairs of rail fitting members 121 have a concave cross-sectional shape that substantially fits the guide rail 111, and the length thereof is formed to be substantially equal to the height of the extension member main body 120. Yes. A pair of rail fitting members 121 that are substantially parallel to each other at a predetermined interval, of the four side walls 122 that constitute the extension member main body 120, of the two side walls 122 that face the guide rail 111 of the container member 11. The extension member main body 120 is embedded in the side surface so as to extend over substantially the entire length in the height direction.
In addition, the cross-sectional shape and number of the rail fitting members 121 and the arrangement position in the extension member main body 120 are not limited to this embodiment, and the cross-sectional shape and number of the guide rails 111 of the container member 11 and the container main body 110 are not limited. The design can be changed as appropriate according to the arrangement position and the like.

Moreover, the four support pins 13 which comprise the holder 10 are for supporting the side wall extension member 12 from the downward direction in a predetermined height position. As shown in FIG. 1, the support pin 13 is provided with an insertion portion 130 having a substantially rectangular cross section substantially matching the pin insertion hole 113 </ b> A of the container body 110, and a pin provided at one end in the longitudinal direction of the insertion portion 130. And a locking head 131 having a substantially rectangular shape in cross section larger than the insertion hole 113A.
In addition, the insertion part 130 should just be a shape which can penetrate the pin insertion hole 113A, and is not limited to this embodiment, A design change is possible suitably. On the other hand, the locking head 131 need only have a shape that cannot be inserted through the pin insertion hole 113A, and is not limited to the present embodiment, and can be appropriately changed in design.

  The receptacle 10 configured as described above can be deformed from the first state shown in FIG. 1 to the second state shown in FIG. That is, when the receiving device 10 is in the first state, the details are not shown in the figure, but first, the side wall extending member 12 is slid upward along the container body 110, and the rail fitting member 121 of the side wall extending member 12 and The side wall extending member 12 is separated from the container body 110 by releasing the fitting of the container body 110 with the guide rail 111.

Then, as shown in FIG. 1, the insertion portions 130 of the four support pins 13 are inserted from the inside of the container main body 110 into the four pin insertion holes 113 </ b> A of the container main body 110. Then, each support pin 13 is inserted to a position where the locking head 131 comes into contact with the inner surface of the container body 110, and on the insertion portion 130 of each support pin 13 protruding to the outside of the container body 110, The lower end edges 122a of the four side walls 122 constituting the side wall extending member 12 in the separated state are respectively placed. As a result, the side wall extending member 12 is disposed on the uppermost portion of the container body 110 while being supported from below by the support pins 13.
At this time, as shown in FIG. 1, by fitting the lowermost part of the rail fitting member 121 of the side wall extending member 12 to the uppermost part of the guide rail 111 of the container body 110, the side wall extending member 12 and The container body 110 is integrated.

  On the other hand, when the receiving device 10 is in the second state, first, the four support pins 13 are pulled out from the pin insertion holes 113A by pulling the four support pins 13 to the inside of the container main body 110 from the state shown in FIG. Then, the side wall extending member 12 that has lost the supporting force from below by the support pins 13 is dropped by its own weight, or the operator pulls it down, so that the container body 110 is guided by the guide rail 111. Slide down along side wall 113.

  Then, as shown in FIG. 2, the side wall extending member 12 is slid downward to a position where the lower end edge 122 a abuts the installation surface 14. At this time, as described above, the height of the side wall 122 of the side wall extension member 12 is substantially equal to the height of the side wall 113 of the container body 110, so that the upper surface 12 a of the side wall extension member 12 is the upper surface of the container body 110. Forms substantially the same surface as 110a.

In the present embodiment, each support pin 13 is inserted into the pin insertion hole 113A from the inside of the container body 110, and the side wall extension member 12 is supported from below by the support pin 13, but the side wall extension member 12 is supported by the support pin 13. The mode of supporting the at a predetermined height position is not limited to this. For example, although not shown in detail in the drawing, the support pin 13 may be inserted into the side wall extending member 12 from the outside, and the support pin 13 may be fitted into a fitting hole (not shown) formed in the container body 110. . In this case, when the support pin 13 is pulled out, the side wall extending member 12 slides downward.
Further, a linear actuator such as a pneumatic cylinder that can be remotely operated may be separately provided as a lifting device that lifts and lowers the side wall extending member 12.

  Next, the work procedure of the liquid jet machining method using the support 10 according to the first embodiment and the operation and effects thereof will be described. Here, FIG. 4 to FIG. 7 are diagrams showing the work procedure of the liquid jet processing method, FIG. 4 and FIG. 5 are schematic sectional views showing the first step, and FIG. 6 is the first step is completed. FIG. 7 is a schematic cross-sectional view showing the second step.

  First, the worker executes the first process, that is, the drilling process. That is, the worker installs the plurality of receiving devices 10 in the first state at predetermined positions on the installation surface 14. More specifically, as shown in FIG. 1, the worker places the side wall extending member 12 on the uppermost portion of the container main body 110 by supporting it from below with four support pins 13. Then, the plurality of receivers 10 in the first state as described above are respectively arranged at positions on the installation surface 14 corresponding to the processing position of the workpiece.

  Next, an operator arrange | positions a to-be-processed body above the installed receiving fixture 10. FIG. That is, as shown in FIG. 4, the operator arranges a plurality of support members 15 on the installation surface 14, adjusts the height of each, and then arranges the workpiece 16 on the support member 15. . At this time, the upper surface 12 a of the side wall extending member 12 constituting the receiving device 10 is in a state of being close to the bottom surface 16 a of the workpiece 16.

  Next, as shown in FIG. 4, the operator places the liquid ejector 17 on the opposite side of the receiving tool 10 across the workpiece 16, that is, above the workpiece 16. The liquid ejector 17 has a nozzle 170 capable of ejecting a water jet. Then, a water jet is ejected from the nozzle 170 toward the machining position 16b of the workpiece 16, and a hole 18 is opened at the machining position 16b. At this time, the jetted water jet and the fragments of the workpiece 16 cut by the water jet are collected into the container member 11 through the extended portion of the side wall 122. Here, since the bottom plate 112 of the container member 11 is composed of a member having excellent wear resistance as described above, the bottom plate 112 is worn and damaged even when a water jet containing an abrasive is directly sprayed. There is nothing.

  Then, as shown in FIG. 5, the operator appropriately moves the nozzle 170 along the workpiece 16 to form the through hole 19 having a desired size and shape. Also during this time, the jetted water jet and the fragments of the workpiece 16 cut by the water jet are collected into the container member 11 through the side wall extending member 12. Thereafter, when the work at the work position 16b is completed, the operator moves the liquid ejector 17 to the next work position 16b to sequentially form the through holes 19. FIG. 6 is a schematic perspective view of the workpiece 16 in which the first step is completed and the plurality of through holes 19 are formed, as viewed from the upper surface 16c side.

  Next, the operator executes the second step, that is, the end face processing step. First, the operator changes the receiving device 10 from the first state to the second state. That is, the operator slides the side wall extending member 12 downward along the container member 11 to the second state shown in FIG. 2 by sliding the plurality of receptacles 10 installed in the first state shown in FIG. And change each. As a result, as shown in FIG. 7, a gap 20 having a predetermined width is generated between each receiver 10 and the workpiece 16.

  Next, an operator installs the end surface processing unit TU. As shown in FIG. 7, the end surface processing unit TU includes an end surface processing machine 21 and a collection tool 22 that are integrally configured. The end face processing machine 21 has a nozzle 210 capable of jetting a water jet, like the liquid jet machine 17, but the water pressure, the amount of water, etc. are suppressed as compared with the liquid jet machine 17 so as to be suitable for detailed machining. It is what was done. On the other hand, the collection tool 22 is a housing having an upper portion made of a member having excellent wear resistance. The operator places the collection tool 22 in the gap 20 below the workpiece 16 by passing through the through hole 19, and the opening (not shown in FIG. 7) is the through hole formed in the first step. 19 is directed to the inner peripheral surface 19a. On the other hand, the operator places the end surface processing machine 21 with the nozzle 210 facing the inner peripheral surface 19a of the through-hole 19 on the opposite side of the collection tool 22 across the workpiece 16, that is, the workpiece 16. It arranges above.

Next, the operator performs end surface processing of the workpiece 16 using the end surface processing unit TU. In other words, the worker jets water jets obliquely from the water nozzles 210 of the end face processing machine 21 toward the inner peripheral surface 19 a of the through hole 19. Thereby, the taper surface 23 is formed when the inner peripheral surface 19a of the through hole 19 is cut off obliquely.
At this time, the water jet sprayed from the end surface processing machine 21, the fragments of the workpiece 16 cut by the water jet, and the like are collected inside the collection tool 22. Here, as described above, since the recovery tool 22 is composed of a member with excellent wear resistance, even if a water jet containing an abrasive is directly sprayed, the recovery tool 22 is worn and damaged. Absent. Then, the operator moves the nozzle 210 along the inner peripheral surface 19 a of the through hole 19 formed in the workpiece 16, thereby forming the tapered surface 23 over the entire circumferential direction of the through hole 19.

In the present embodiment, as the end face processing machine 21 used in the second step, a machine that cuts the workpiece 16 by spraying a water jet is used. A laser cutting machine (not shown) may be used. Further, in the present embodiment, the taper machining is described as an example of the end surface machining performed on the workpiece 16, but the end surface machining is not limited to the taper machining, and may be chamfering, for example.
Further, the material, shape, and size of the recovery tool 22 are not limited to the present embodiment as long as the scattered matter generated in the second step can be recovered, and can be appropriately changed in design.

According to the liquid jet machining method using the receiver 10 according to the first embodiment described above, the receiver 10 and the recovery tool 22 are large enough to cover only the vicinity of the processing position 16b in the workpiece 16. It ’s enough. Therefore, as compared with the case where the entire workpiece 16 is covered with the receiving tool 10 and the collecting tool 22, the receiving tool 10 and the collecting tool 22 can be downsized to reduce the manufacturing cost, and the receiving tool 10 and the collecting tool 22 can be reduced. The cost of water stored inside the tool 22 can also be reduced.
Further, when the operator needs to perform the second step, the end surface processing is performed with the workpiece sandwiched between the holes formed in the first step after the completion of the first step. The collection tool may be disposed at a position opposite to the machine, and it is not necessary to previously form a hole for allowing the collection tool 22 to pass through the workpiece 16. Therefore, the accessibility to the processing position 16b of the AWJ processing machine including the end face processing machine 21 and the collection tool 22 is good, and the processing work can be simplified.

  Next, the structure of the receiving tool 10 which concerns on 2nd Embodiment of this invention is demonstrated. FIG. 8 is a schematic cross-sectional view illustrating a receiving tool 30 according to the second embodiment. Compared with the receiver 30 of the first embodiment, the receiver 30 according to the present embodiment has a plurality of wheels 31 rotatably provided at the bottom of the container member 11 and the workpiece on the installation surface 14. The difference is that a guide rail 32 is laid along the body 16. In addition, since structures other than the wheel 31 which comprises the receiving device 30 are the same as the receiving device 30 of 1st Embodiment, description is abbreviate | omitted here and the same code | symbol as the receiving device 30 of 1st Embodiment is used.

  According to such a configuration of the receiver 30, the receiver 30 can move along the guide rail 32 by the wheels 31 being guided by the guide rail 32. Accordingly, when there are a plurality of machining positions 16b on the workpiece 16, the receiving tool 30 can be shared by sequentially moving the receiving tool 30 from one machining position 16b to another machining position 16b. . Thereby, compared with the case where the receiving tool 30 is installed separately for every processing position 16b, the cost reduction by material cost reduction can be aimed at.

  Next, the structure of the receptacle 40 which concerns on 3rd Embodiment of this invention is demonstrated. FIG. 9 is a schematic cross-sectional view illustrating a receiver 40 according to the third embodiment. Similar to the receiver 40 of the first embodiment, the receiver 40 according to the present embodiment is provided with a container member 41 that is a casing having an open top, and covers the outer periphery of the container member 41 and slides up and down. And a support pin for supporting the side wall extension member 42 from below. However, the container member 41 and the side wall extending member 42 differ from the first embodiment in that the opening width of the upper opening can be adjusted. In FIG. 9, the support pins are not shown for convenience of explanation.

  The container member 41 is divided into two parts, a first container member 411 and a second container member 412, and a pair of guide rails 111 are provided on each outer surface.
