The plate material is fed to a position between the upper die 100 and the lower die 200 to be processed.

Further, referring to fig. 2, a die 300 and a bending punch 400 are provided under the upper die 100. The die cutter 300 is responsible for the cutting process, and the bending punch 400 is responsible for the bending process.

Still further, a processing concave position 210 is arranged on the upper side of the lower die 200, and a punching tool concave position 221 is arranged in the processing concave position 210. The die 300 and the bending punch 400 correspond to the processing recess 210, and the die 300 corresponds to the die recess 221.

Further, the die cutter 300 cooperates with the die cutter concave 221 to complete the cutting process. That is, the die cutter 300 can be inserted into the die cutter pocket 221 to complete the process of cutting the continuous sheet material into individual pieces.

Still further, referring to fig. 3, the machining recess 210 completes the bending process in cooperation with the bending punch 400. That is, the bending punch 400 may be used in conjunction with a process for bending the individual workpieces by machining the edges of the recess 210.
