However, in the conventional cartridge-type punch press, when a tool to be used this time is selected from a plurality of tools mounted on the cartridge, the cartridge is moved with respect to a fixed press head. It is configured to be selected. Therefore, the processing accuracy depends on the positioning accuracy of the cartridge, and it is difficult to increase the processing accuracy. In addition, it is necessary to move a heavy-weight cartridge to select a tool, and it is not possible to position the cartridge at high speed, and it takes time to select a tool. Although it is possible to shorten the positioning time of the tool by reducing the size of the cartridge, it is possible to reduce the number of tools that can be mounted on a single cartridge by reducing the size of the cartridge. Therefore, frequent replacement of the cartridge is required, and it takes time to change the tool. Further, in the conventional cartridge-type punch press, it is necessary to discharge all the cartridges outside the machine in order to replace a tool provided in the punch press body.
Therefore, the machining must be temporarily interrupted, and the interruption time of the machining becomes longer.

An object of the present invention is to provide a punch press capable of performing high-precision machining and shortening a tool selection time for selecting a tool on a cartridge. It is another object of the present invention to provide a simple structure and a small moving range of the punch driving means. Still another object of the present invention is to make it possible to insert / remove a cartridge with a simple configuration, and to move or insert / remove only an upper cartridge or only a lower cartridge, so that various forms can be used.

In the case of a long plate material W, after the plate material is fed by the first plate material feed means 10 and processed, it is transferred to the second plate material feed means 11, but before the transfer operation, the second material of the plate material W is transferred. Both side edges gripped by the plate material feeding means 11 are cut off as shown by cut-off portions Wa in FIG. The cut-off portion Wa is gripped by the second plate material feeding means 11. The plate material W before punching does not have sufficient accuracy such as the linearity of the long side in many cases. However, by cutting off as described above, the sheet material W is fed by the first plate material feeding means 10. The positional relationship between each processed portion and the cut-off portion Wa is correctly maintained irrespective of the outer peripheral shape of the plate material W when the material is used. Therefore, by gripping the cut-out portion Wa with the second plate material feeding means 11 as described above, the cut portion Wa is fed by the first plate material feeding device 10 and punched, and
Accuracy between the second plate material feeding means 11 and the machined part punched by feeding is ensured. When the cut-off portion Wa is gripped by the second plate feeding means 11 as described above, the cross slide 53 is moved by the width of the cut-off portion Wa (the width in the Y direction), and the moving-side work holder means 55 is fixed. Closer to the work holder means 54 on the side. Thereby, while processing the cut-off portion Wa on the side edge of the plate material W, the first plate material feed means 10 and the second plate material feed means 1
1 can be properly delivered.

After passing the plate material W as shown in FIG. 5, the first plate material feeding means 10 performs, for example, one of the following three types of operations. . The plate material W escapes outside the machine in the first direction (X direction) so as not to hinder the movement of the plate material W in the second direction (Y direction). . When the plate material W is a considerably long material, the plate material W is fed in cooperation with the second plate material feeding means 11 in order to keep the plate material W from being gripped and to smoothly feed the plate material.
. The sheet material W is moved in the first direction (X) until the sheet material W does not interfere with the first feeding means 10 by the feed of the second sheet material feeding means 11.
Direction), the next plate is loaded.

FIG. 6 shows another embodiment of the present invention.
