The first positioning through hole 11 is matched with the electric power fitting 7 in size and shape, and can be accurately positioned.

Subsequently, the trimming punch 2 descends, bringing the trimming die 8 down together. The trimming die 8 and the trimming die 9 are matched with each other to cut off the flash of the electric power fitting 7. The scrap produced during the cutting process falls through the gap one 10 between the trimming lower die 9 and the trimming blanking table 4.

After finishing the trimming operation, the first pushing member 6 located in the first gap 10 starts to act, pushes out the trimmed electric power fitting 7 from the first positioning through hole 11, and smoothly pushes the electric power fitting to the punching lower die 5 along the first gap 10, so as to prepare for the punching process.

Therefore, in the whole punching process, the generated waste can be timely and orderly discharged out of the equipment without piling up in the equipment, thereby ensuring the continuity and stability of processing.
