[0083] The working principle of the utility model is as follows:

[0084] In the punching process, after the mold starts to work, the upper die goes down, the bending upper punch 4 and the push plate 13 press the part up and down respectively, because the downward pressure of the bending upper punch 4 is greater than the upward force of the push plate 13, so the part moves downward, and the bending gradually forms.

[0085] At this point, in a one-time movement process, the combined action of bending and punching is realized in turn.

[0086] In addition, in the mold, a unique method is designed to handle the waste generated by the punching gap. As per the conventional method, the waste is discharged by falling downward on the surface of the lower die push plate, which will be difficult to clean completely due to the small size of the waste, which may cause part stacking or mold damage accidents, and thus is not desirable. The scheme of the mold is as follows: a waste storage groove is designed in the punching die, and the punching waste moves upward and can enter the groove and be stored therein. Because the waste is small, a large number of wastes can be accumulated. When a certain amount is reached, it is timely removed.
