are arranged radially around the sliding shaft 7. Furthermore, the die 5 is located at each corner of the guide plate 81.
The chamfering punch parts 8f, 8g, 8h, 8k, which are assembled in sections with the chamfering die parts 5f, 5g, 5h, 5k, and serve as a plurality of irregular square cutting male molds for chamfering, are assembled on the sliding shaft 7.
They are arranged radially around the center.

The punch 8 is provided with a screw hole 8n on its annular surface that matches the stepped hole 6a penetrated through the head 6. It is attached concentrically and replaceably to the bottom of the unit.

In this case, by attaching each notch punch part 8b to 8e so as to match the notch die part 5b to 5e to be exclusively assembled, each chamfer punch 8f to 8k can also be attached to the chamfer die part to be exclusively assembled. Matches 5f to 5k. Next, the effect will be explained.

The composite press mold A having the above configuration is placed on the bed of a known general press machine (not shown), almost concentrically with the ram, and the base 1 is rotated while being held concentrically when processing irregularly shaped products. Fix it in such a way that it is possible.

Further, a pressing member for pressing down on the upper surface of the head 6 is attached to the lower end of the ram. Moreover, the notch mold desired to be machined is oriented toward the front side of the bed. Furthermore, the diameter of the sliding shaft hole 2a of the receiving cylinder 2 is reduced by tightening the tightening screw 11, or the diameter is enlarged by pushing the slot 2b toward the other side by tightening the push screw 12. or by any means, the sliding shaft hole 2
The fitting state of the sliding shaft with respect to a is adjusted so that the operation of the shearing process using the die 5 and punch 8 can be performed optimally and smoothly. As a result, when the processing plate B shown in FIG. 6, for example, is placed on the notched die portion located on the front side of the die 5 and the ram is moved downward, the cutout is made on the front side. When the notch die part 5b is located, the notch punch part 8b assembled therewith is lowered by the downward pressure movement of the ram against the head 6, and it is possible to perform notch processing on a predetermined surface part of the work plate B. can. To illustrate this, a round notch 17A like the one on the left side of FIG. 6 can be formed by press working. After notch processing, the ram rises, and the punch 8 integrated with the head 6 is released from the lower pressure state.
can automatically rise and return to a predetermined height using the restoring force of the spring 9 against the sliding shaft 7. in this case,
The sheared notch waste (not shown) falls into the chute 2c directly below, as is clear in FIG. Therefore, the notch chips are automatically removed to the outside of the receiving tube 2 each time the shearing is performed. In this way, continuous notch machining can proceed with high efficiency. In addition, when changing the mold to move on to machining an irregularly shaped notch, loosen the tightening of the base 1 and the base 1 will rotate in any direction, so you can easily and quickly create the desired irregularly shaped notch. It can be placed on the front side of the bed.

Then, by tightening and fixing the base 1 again, the mold exchange can be easily completed. In this way, the mold can be replaced simply by rotating the base 1.

Therefore, as shown on the left side of FIG. 6, the irregular round-shaped notches 17A, ITB, 17C, and 17D can be easily and quickly pressed into each type of work plate. . Next, when chamfering a plate whose corners have been cut at right angles, rotate the base 1 in the same way as described above to cut the recess 51 in which the desired chamfering die is placed. After positioning and fixing it on the front side of the plate, the ram is moved with the right angle part of the processed plate in contact with the stepped vertical surface of the notched die part whose two sides are adjacent to this recess 51. When it moves downward, for example, if the chamfered die part 5f is located on the front side,
The chamfering punch portion 8f assembled therewith descends due to the downward pressure movement of the ram against the head 6 and shears the corner portion.

To illustrate this, a desired corner of the work plate C can be press-worked into a rounded chamfer 19F, as shown on the upper left shoulder in Figure T. After shearing, the punch 8 returns to the upward position by the spring force, as described above. Also, sheared chamfer scraps (
(not shown) descends to the chute 2d directly below, then slides down in conjunction with any chute 2c adjacent to this chute 2d, and is automatically removed to the outside of the receiving tube 2. . In this way, continuous chamfering can proceed with high efficiency. Furthermore, when changing the mold to start machining an irregularly shaped chamfer, loosen the tightening of the base 1 and rotate it in any direction as described above to easily and quickly create the desired irregularly shaped chamfering mold. Since it can be positioned on the anterior side, mold replacement can be easily completed.

In this way, the mold can be replaced simply by rotating the base 1. Therefore, as shown in FIG. 7, irregular rounded chamfers 19F, 19G, 19H, and 19K can be easily and quickly pressed onto the corners of each type of work plate. Note that a die of a different type (not shown) is placed and fixed on the top of the receiving cylinder 2 in place of the aforementioned die 5, and on the bottom surface of the head 6,
In place of the punch 8 described above, a punch of a different type (not shown) to be combined with the punch 8 may be attached, for example, a sixth punch.
Irregular rectangular notch 18A, 1 as shown on the right side of the figure
The notches 8B, 18C, and 18D can be pressed easily and quickly on each type of work plate by the same simple die exchange operation as described above.

Also, by using the same die and punch, different types of oblique chamfers 20F, 20G, 20H, 20K are produced as shown in Fig. 8.
However, it can also be easily and quickly pressed into the corners of each type of processed plate.

As explained above, this invention has a plurality of irregularly shaped notch molds arranged radially around the sliding shaft, and a plurality of chamfer molds arranged radially in the recesses between the notch molds. do,
By concentrically arranging different types of molds in the same mold body, the number of molds can be significantly reduced, storage space can be reduced, and mold costs can also be reduced. can be reduced overall.

In addition, mold replacement becomes easier and high-mix, low-volume production can be performed with high efficiency, which not only reduces the cost of press processing, but also improves the functionality of press molds by combining different types of molds. There is.
