The bottom of the upper die 14 is sequentially provided with punching punches along the conveying direction of the steel belt 1 . Head 2, chamfering punch 3, blanking and bending punch 4 and re-bending punch 5, the punching punch 2, chamfering punch 3 and blanking and bending punch 4 are located in the first horizontal direction , the blanking and bending punch 4 and the re-bending punch 5 are located in the second horizontal direction, the first horizontal direction is perpendicular to the second horizontal direction, and the lower die 15 is provided with the punching punch 2 The matched punching die 16, the chamfering die 17 matched with the chamfering punch 3, the blanking and bending die 18 matched with the blanking and bending punch 4, and the rebending die matched with the re-bending punch 5. Bending die 19.

In this embodiment, in order to facilitate pushing the insert to the re-bending station, a blanking translation drive mechanism 20 is provided between the upper die 14 and the lower die 15; wherein, the blanking translation drive mechanism 20 is The structure preferably includes, but is not limited to, a blanking push rod 6, a power rod 9, a blanking slider 10 and a blanking return spring 11. The lower die 15 is provided with a first sliding groove 21 along the second horizontal direction. The blanking slider 10 is slidably installed in the first sliding groove 21, the rear end of the blanking push rod 6 is fixed to the top of the rear end of the blanking slider 10, and the front end of the blanking slider 10 is provided with a front Inclined surface 25, the upper end of the power rod 9 is fixed on the upper die 14, the lower end of the power rod 9 is installed with a roller 22 that rolls with the front inclined plane 25, and the two ends of the blanking return spring 11 are respectively connected to the falling material.
