S2, machining an upper die on the stamping mechanism (5) by adopting a wire-cut electric discharge machining process to improve the precision, and machining a lower die holder (6) on the punching platform (1) by adopting a grinding process to improve the dimensional precision and the surface roughness so as to be more matched with the stamping mechanism (5);
S3, quenching and tempering the spring in the spring column (79) to increase the toughness and strength of the spring, polishing the surface of the spring, performing low-temperature stress relief treatment, and correcting the appearance.
