Specifically, two groups of lower die assemblies 2 and multiple groups of lower alignment blocks 7 are fixed on a base, a first lifting device is connected to the pressing assembly 1, and a second lifting device is connected to two groups of driving seats 5. When punching holes in the workpiece 3, the first lifting device drives the pressing assembly 1 to clamp the workpiece 3 on the two groups of lower die assemblies 2, thereby ensuring the stability and accuracy of the workpiece during processing.

[0041] The upper die assembly 4 includes an upper die base 41, a punch 42 and a nitrogen spring 43. Specifically, the free end of the punch 42 corresponds to the position of the hole groove 22. When the upper die assembly 4 punches the workpiece 3, the free end of the punch 42 enters the hole groove 22, and the multiple groups of nitrogen springs 43 are in a retracted state. When the upper die assembly 4 is raised, the multiple groups of nitrogen springs 43 extend and push the workpiece 3 to prevent the workpiece 3 from sticking to the pressure seat 13, making it easy to replace the workpiece 3.
