Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for processing the end of a profile used for sashes and the like.

When assembling a sash or the like using molded materials, it is necessary to perform processing such as cutting off both ends depending on the purpose. The cross-sectional shape of the mold material usually has an extremely complicated shape, as shown in FIG. 1A, for example. If you want to cut off the entire cross section of something like this, you can simply cut it using a saw such as a circular saw. but,
As shown in Figure C, the end of the shaped material A having the cross-sectional shape shown in the figure has a protrusion b protruding at right angles from the surface a.
If you need to leave a chisel and cut the rest to a certain width, you cannot cut it with a saw alone. In such a case, generally, as shown by the dotted line in Figure B, the right part B of the protrusion b on surface a is cut in advance, and then cut along the Y plane, and then the protrusion b and the protrusion b are cut. Cut along the X plane to cut off the connected parts. Not only in this case, but also in cases where processing cannot be performed in one step and requires processing in two or more steps, it is extremely inefficient to process each step using separate processing equipment. In particular, in the case of the shape A shown in the figure whose cross-sectional shape is not symmetrical, it is not possible to use the same processing equipment for processing one end and the other end. A device for processing the other end is required, and a great deal of labor is required just to set the mold material in each processing device.

The present invention has been made with these points in mind, and it is an object of the present invention to provide a method and apparatus that can easily process a part of the end of a molded material having a complicated cross-sectional shape. .

Therefore, the first invention provides at least two processing sections: a first processing section and a second processing section that processes a part other than the section processed by the first processing section,
Arrange these on a straight line in the longitudinal direction of the mold material, and
A part of the mold material is cut by the lower mold, which is fixedly placed in the machining part, and the lower mold moves up and down relative to the lower mold. It is characterized by comprising an upper mold that is retracted to a position where it does not interfere with the

As a result, in the first processing section, cutting is performed by moving the upper mold downward, and by leaving the upper mold waiting in the retracted position, and pushing the mold material, the mold material can be installed in the second processing section. can.

Further, the second invention is such that a stopper is attached to the upper mold of the first invention, thereby facilitating positioning of the mold material in the first processing section.

A third invention is one in which the same thing as the first invention is added for machining the other end, and at that time, both first machining parts are driven by the same driving means, and one of them is mutually moved to the retracted position. At some point, the other one returns to its original position.

The illustrated embodiment will be described below. FIG. 2 is a plan view of an embodiment of the apparatus of the present invention in which a processing means for cutting along the Y plane, which will be described later, is omitted. A second processed portion 4 at the other end is formed on the substrate 5 .

The first processing section 1 and the second processing section 2 are on the same straight line, and by pushing the mold material A partially processed in the first processing section 1 as it is, it can be sent to the second processing section 2. It's summery. The other end first processed section 3 and the other end second processed section 4 are in the same positional relationship as the first and second processed sections. As shown in FIG. 5, a processing means 7 having a circular saw is attached above the second processing section 2 and the second processing section 4 at the other end. The mold material A is fed from the left side of the first processing section 1 in the drawing, the tip is stopped in the first processing section 1 and processed, and then transferred to the second processing section 1.
It is sent to the processing section 2, where it is first cut along the Y plane by the processing means 7, and finally cut along the X plane. The shaped material A after processing is sent to the left side in the drawing and removed, and the other end is similarly processed by the other end first processing section 3 and the other end second processing section 4.

Each processing section and the relationship between each processing section will be explained below. A mold material holder 8 common to the first processing section 1 and the other end first processing section 3 is attached to the center of the substrate 5. The first processing section 1 and the first processing section 3 at the other end are constituted by members that are substantially symmetrical to each other. This mold material holder 8 is approximately rectangular, and surfaces 8a and 8b are parallel to the direction in which the mold material A travels. The surface of this mold material holder 8 is flat. Reference numeral 9 designates a lower die for the first processing section 1, and 10 indicates a lower die for the other end of the first processing section, which are fixedly attached to the substrate 5. The lower mold 9 is attached along the surface 8a of the mold holder 8, and a surface 9a facing the surface 8a is formed parallel to the surface 8a with a constant distance therebetween. A protrusion b of the profile A that remains uncut is inserted between these surfaces 8a and 9a. In order to facilitate insertion of the protrusion b here, the corners of the surfaces 8a and 9a are chamfered as shown. The same holds true for the relationship between the surface 8b of the mold material holder 8 and the surface 10a of the lower mold 10. The upper mold 11 is arranged so that one surface 11a is in contact with a surface 9b formed at right angles to the surface 9a of the lower mold 9. The lower die 10 and the upper die 12 of the other end first processing section 3 have a similar relationship. The upper molds 11 and 12 each have an upper mold holder 13,
The cutting process and the returning process are performed alternately with the surfaces 9b and 11a and the surfaces 10b and 12a kept close to each other by a cam mechanism, which will be described later. Alternatively, the portion B inserted into the descending portion of 12 is cut. Stoppers 15, 15 attached to the ends of the upper molds 11 and 12 are provided for setting the processing position of the mold material A by placing the tip of the mold material A thereon. A guide 1 attached to the substrate 5 so as to surround the upper mold holders 13 and 14
Reference numerals 6 and 16 serve as guides in the moving direction of the upper die holders 13 and 14. Guide 1 of first processing section 1
Air cylinder 1 installed near 6
7 is for driving the upper molds 11 and 12. This drive means is shown in FIG. The air cylinder 17 has one end attached to the cylinder mounting material 1 to a holder 18 attached to the substrate 5.
It is attached via 9. One end of the cylinder mounting member 19 is inserted between the upright support portions 18a and 18b of the holder 18, and is attached to the holder 18 by a pin 20 passing between them. The other end of the cylinder mounting member 19 is threaded from its surface toward the holder 18, and the holder 17 is mounted by inserting the male thread at the end of the cylinder 17. One end of a link 21 is rotatably attached to the tip of a piston 17a of this cylinder 17. A cam 22 is fixed to the other end of this link 21. This cam 22 is held by guides 23, . . . so as to be movable in parallel along the back side of the substrate 5. The cam 22 is a plate having a constant width and thickness, and has oblique long holes 24 and 25 formed in the portions where the holders 13 and 14 that hold the upper molds 11 and 12 are located. At the mounting locations of the upper molds 11 and 12 and the holders 13 and 14 of the substrate 5, holes are provided through which these can be penetrated. As shown in FIG. 4, the holder 14 of the upper mold 12 consists of a mold mounting part 14a to which the upper mold 12 is attached, and leg parts 14b and 14c below the mold mounting part 14a, which are divided into two. This leg portion 14b,
A pin 26 attached between the holes 14c is inserted into the elongated hole 25. That is, due to the inclination of the long hole 25 and the pin 26, the movement of the cam 22 causes the holder 14 to move in the vertical direction in the drawing. This holder 14 and upper mold 12
is moved from a part where its upper surface is located slightly below the surfaces of the lower mold 9 and the mold material holder 8 to a position where the upper mold 12 does not interfere with passing the mold material A placed on the lower mold 9 and the holder 8. It can be raised to The vertical movement of the upper die 12 by the holder 14 and the cam 22 is exactly the same for the upper die 11. However, since the direction of inclination of the elongated hole 24 is opposite to that of the elongated hole 25, the directions of vertical movement of the upper molds 11 and 12 are opposite. That is, when the upper mold moves downward and is in the cutting process, the upper mold 12 moves upward and enters the return process. Conversely, when cutting with the upper mold 12, the upper mold 11 moves upward. Due to this downward movement of the upper mold 11, an upper mold is formed between the surface 9b of the lower mold 9 and the surface 11a of the upper mold 11 and with a gap equal to the thickness of the protrusion b from the surface 8a. Part B of the mold material A is cut by the teeth 11b of the mold 11. The cam 22 that moves the upper molds 11 and 12 up and down is the piston 17 of the cylinder 17.
Needless to say, this is performed by the reciprocating motion of a. Although the stopper 15 is omitted in FIG. 3, the stopper 15 is attached to the upper molds 11 and 12 and moves together with the upper mold, so that it does not obstruct the progress of the mold material A together with the upper mold after cutting. evacuate to.

In this way, the first processed part 1 and the other end first processed part 3
If these are placed side by side, and the movement of both upper dies for processing is configured such that the movement direction of one is opposite to that of the other, the air cylinder 1
Two places can be machined by one reciprocation of the piston 17a. That is, when the piston 17a is caused to protrude to the right in the drawing in the first processing section 1, the cam 22 similarly moves to the right in the drawing via the first link 21, and is moved upward by the inclination of the elongated hole 24. The mold 11 moves downward and processes the mold material. During this time, the upper mold 12 of the other end first processing section 3 is moved upward by the slope of the elongated hole 25, and waits so that the other end of the mold material which has not yet been processed can be inserted here. If the piston 17a of the air cylinder 17 is returned to its original position after the other end of the mold is inserted, the other end of the mold can be processed by the upper die 12 by performing the reverse operation.

When processing with the upper mold 11 or 12, the upper surface of the upper mold and the upper end of the stopper 15 are lowered below the surface of the mold holder 8, as described above.
Therefore, the shaped material processed here can be slid and sent from that position to the second processing section 2 and the other end second processing section 4, respectively. A mold holder 27 having a similar shape to the mold holder 8 and for a second processing portion at the other end is attached to the substrate 5 . The side surface 27a thereof is flush with the surface 8a of the mold material holder 8, and the side surface 27b is similarly attached so as to be flush with the surface 8b.
Similarly, the side surfaces 28a, 29a of the profile guides 28, 29 attached to the mold guides 28, 27b at a constant interval are connected to the surface 9a of the lower mold 9 and the surface 10a of the lower mold 10.
It is installed so that it is flush with the Therefore, the mold material A processed in the first processing section 1 or the other end first processing section 3 can be set in the second processing section 2 or the other end second processing section 4, respectively, by pressing it as it is after processing. can. Stoppers 30, 30 are attached to the tips of the slits formed by the side surfaces 27a and 28a and the side surfaces 27b and 29b,
The processing position of mold material A is regulated.

The shaped material A brought here is first processed by processing means 7.
is cut along the Y plane. The processing means 7 mainly consists of a cutting section 32 having a circular saw 31 and a holder 33 for holding down the shape material A during cutting with the circular saw 31. The circular saw 31 is always placed inside a protective cover 34 for safety, and is attached by a handle 35 so as to rotate around a point 36. The circular saw 31 comes out from the protective cover 34 when it is rotated and lowered. A bag 37 attached to the rear of the cutting section 32 is for storing chips. Stoppers 32a, 32a are attached to the cutting portion 32 to prevent the circular saw 31 from descending more than necessary. Further, a stopper 32b is attached on the opposite side of the stopper 32a so as to contact the holder 33, so that the cutting cannot be performed unless the holder 33 is lowered. The holder 33 is composed of an air cylinder 33a and a contact portion 33b that is moved up and down by the air cylinder 33a and presses down the mold material.
Shape material holder 2 for the second and other end second processing parts
7 has a shape as shown in FIG.
Circular saws 31 are installed at both ends of the surface 27c perpendicular to a and b.
Slanted relief grooves 27d, 27d are formed to provide relief for the mold material holder 27, and a treatment according to the shape of the mold material is formed on the surface of the mold material holder 27 to stably hold the mold material A to be cut together with the holder 33. A groove 27e and depressions 27f, 27f are formed for attaching a tool (not shown). circular saw 31
The stoppers 32a, 32a do not allow the groove to fall below the relief groove 27d. The circular saw 31 cuts the shape material A along the Y plane. Needless to say, the protrusion b should be left in place.
Therefore, in order to cut off the portion from this cut point to the end, it is necessary to further cut along the X plane. The auxiliary cutting means performs the cutting along the X plane, and this auxiliary cutting means is constituted by the mold material holder 27, mold material guides 28, 29, and upper molds 38, 39. The upper molds 38, 39 are configured to move vertically, that is, horizontally, in FIG. 2 along the surfaces of the mold material guides 28, 29 and the mold material holder 27, , 39a and the upper surface of the mold material holder 27 serving as the lower mold, the remaining portion of the mold material A is cut off.

FIG. 8 schematically shows the drive mechanism for the upper dies 38, 39. An air cylinder 40 is provided on the back side of the substrate 5. This one air cylinder 40 can move both upper molds to the cutting position at the same time. That is, holders 41 and 42 holding upper molds 38 and 39 are provided at the tip 40a of the piston and the end 40b of the cylinder, respectively.
Drive members 43 and 44 are attached, respectively. As shown in FIG. 2, guides 45 and 46 having a space in the center are attached to the attachment points of the drive members 43 and 44 of the board 5, and guides 45 and 46 are installed in the holes formed by this space and the notches provided in the board. Drive members 43, 44 are movably mounted.

The details of the upper mold 39 are as shown in FIG. 9, and the holder 42 is slidably held by the movement of the drive member 44 between two holder guides 47, 47 formed in an inverted L shape. has been done. This holder 4
An upper die 39 is attached to the front edge of 2. The front edge surface of this holder 42, that is, the upper mold 3
The lower surface of 9 is a mold material guide 29 and a mold material holder 27.
The tooth portion 39a at the tip of the upper die 39 advances along those surfaces,
It is configured to cut off the shape material A along the X plane.

The processing method according to the above embodiment will be described. First, the protrusion b of the molded material A is pushed while being inserted between the surfaces 8a and 9a, and the molded material A is set at a predetermined position regulated by the stopper 15 of the first processing section 1. The upper mold 11 is then above the surface of the profile holder 8 and the upper mold 12 is therefore hidden from this surface. After setting the mold material A, the air cylinder 17 is operated to move its piston 17a to the right in FIG. 3. Then, as shown in FIG. 3, the cam 22 moves to the right in the drawing, lowers the upper mold 11 through its elongated hole 24, and raises the other upper mold 12. As the upper mold 11 descends, a portion B of the mold material A is cut off. Upper mold 11
Since the tip of the mold material A descends below the surface of the mold material holder 8, the mold material A can be sent to the next second processing section 2 by pushing it as it is. The mold material A is stopped at a predetermined position by the stopper 30. As mentioned above, the shape material A is held down by the holder 33 of the processing means 7 and the jig inserted into the groove 27e or the recess 27f as necessary, and the shape material A is cut along the Y plane with the circular saw 31. and cut. Next, the air cylinder 40 is operated to move the upper mold 38 vertically in FIG. 2, and the mold material A is cut along the X plane to complete the machining. After returning the upper mold 39 to its original position, the mold material A can be pulled out. To process the other end of this profile A, insert the other end into the first processing section 3 with the end to be processed facing forward until it hits the stopper 15 in the same manner as above, and then perform the same operations as above. good. Due to the above-described operation of the air cylinder 17, the upper mold 12
Since the mold is raised upward, the upper mold 12 can be lowered and cut by simply operating the air cylinder 17 and returning it to its original position. Of course, the upper mold 11 also rises at the same time. The subsequent processing is exactly the same as that of the one end described above. Note that the driving means for the upper molds 11 and 12 is not limited to an air cylinder, and other means such as a hydraulic cylinder may be used. Furthermore, although the lower molds 9 and 10 are made separate, it is also possible to form them on one block depending on the arrangement of the upper mold.

In the first invention, the first processing section and the second processing section are arranged on a straight line in the longitudinal direction of the mold material, and the first processing section is arranged on a lower mold which is fixedly arranged, and the first processing section is moved up and down with respect to the lower mold. ,
By moving downward, the lower mold cuts a part of the mold material, and the upper mold moves away from the straight line and retreats to a position where it does not interfere with the progress of the mold material. After cutting the end portion of the mold material, it becomes possible to install it in the second processing section by simply pushing the mold material, making it extremely easy to install the mold material in the second processing section. Therefore, it becomes possible to shorten the working time.

Further, in the second invention, since the upper die of the first invention is provided with a stopper for positioning during processing of the mold material in the first processing section, it becomes easy to install the mold material in the first processing section.

Furthermore, in the third invention, the first and second processing sections for the other end of the shape material are arranged side by side, and the upper die of the first processing section is operated by a common driving means, so that when one is on top, the other is on the bottom. Since the reciprocating motion of the driving means is also processed, unnecessary motion can be eliminated.

Furthermore, in these inventions, the upper die of the first processing part retreats during processing and does not hinder the progress of the die, and the upper die with the blade is located below, so the middle part of the die can be processed with confidence during the first processing. The machine can be processed in the second processing section while being placed in the same position as the first processing section, and the distance between the first processing section and the second processing section can be shortened, making it possible to downsize the entire device.
