Under the guidance of the driving guide plate 23, the upper die inclined wedge slider 22 is pushed to slide along the angular direction of the driving guide plate 23, so that the upper die inclined wedge slider 22 drives the punch assembly 29 to move together. The inner wall of the top of the lower template 1 is fixedly connected with a guide block 7, and the guide blocks 7 are linearly arranged along the outer wall of the lower template 1.

[0024] Working principle:

[0025] This mechanism is mainly composed of a lower template 1, a positioning plate 9, an upper template 2, a stamping mechanism 3, a part 4, a first stamping plate 5 and a second stamping plate 6. The positioning plates 9 are fixedly connected to the corners around the lower template 1. The upper template 2 slides relative to the lower template 1 through the positioning plates 9 to ensure the position accuracy during the stamping process.

[0026] The stamping mechanism 3 is the core part of this compound inclined wedge mechanism. The upper die guide plates 21 in a linear array are slidably connected to the top of the upper die inclined wedge slider 22 in the stamping mechanism 3. The upper die inclined wedge slider 22 is connected to the upper template 2 and the lower die inclined wedge slider 24 through the driving guide plate one 23 and the driving guide plate two 210 respectively.
