When the upper die holder 42 moves up and down, the first clamp driving rod 735 and the second clamp driving rod 736 are driven to move, so as to switch the abutting position of the first connecting piece 733 on the pushing surface of the first clamping jaw and the abutting position of the second connecting piece 734 on the pushing surface of the second clamping jaw, so that the first clamping jaw 731 and the second clamping jaw 732 clamp or unclamp a product. One end of the clamping jaw elastic piece is connected with the first connecting piece 733, the other end of the clamping jaw elastic piece is connected with the second connecting piece 734, and the clamping jaw elastic piece gives the elastic force that the first connecting piece 733 always abuts against the first clamping jaw pushing surface and the second connecting piece 734 always abuts against the second clamping jaw pushing surface.

The punching device has at least two extreme operating states: a ready state and a molding state. When the stamping device is in a ready state, the first connecting rod is abutted against the first clamping jaw low-level surface 7352, the second connecting rod is abutted against the second clamping jaw low-level surface 7362, and the traction rod 542 is abutted against the traction low-level surface 5432; when the stamping device is in the stamping working state, the first connecting rod is abutted against the first clamping jaw high-level surface 7351, the second connecting rod is abutted against the second clamping jaw high-level surface 7361, and the traction rod 542 is abutted against the traction high-level surface 5431. Namely, when the stamping device is in a die pressing working state, the first clamping jaw 731 and the second clamping jaw 732 clamp the product, the stamping module performs stamping on the product on the corresponding station, and the rolling module performs die assembly and rolling on the product on the corresponding station; when the stamping device is in a ready-to-operate state, the first clamping jaw 731 and the second clamping jaw 732 loosen the product, the stamping module resets, and the rolling module opens. The stroke of the first connecting rod abutting against the first clamping jaw low-level surface 7352 and the stroke of the second connecting rod abutting against the second clamping jaw low-level surface 7362 are shorter than the stroke of the traction rod 542 abutting against the traction low-level surface 5432, so that the first clamping jaw 731 and the second clamping jaw 732 clamp the product first and then the rolling die set performs die assembly; otherwise, the stroke of the first connecting rod abutting against the first clamping jaw high-level surface 7351 and the stroke of the second connecting rod abutting against the second clamping jaw high-level surface 7361 are longer than the stroke of the traction rod 542 abutting against the traction high-level surface 5431, so that the rolling module is firstly opened, and then the first clamping jaw 731 and the second clamping jaw 732 are loosened.
