| description | The invention relates to a manufacturing method of a cold stamping die pressure plate with a flexible pressing function, which comprises the steps of structural design of the pressure plate, numerical control machining of a foam cavity, pre-machining of a structural surface, phosphating of the pre-machined structural surface, pre-embedding of an anti-falling screw on the structural surface, surface hardening treatment of the foam cavity, arrangement of a pouring system for an elastomer resin material to flow in on the foam cavity, sealing and fixation of the foam cavity and a structural surface, stirring and vacuum defoaming of the elastomer material, pouring and curing of the elastomer resin material, removal of the foam cavity, numerical control machining as well as assembly and debugging. According to the manufacturing method of the cold stamping die pressure plate with the flexible pressing function, the surface quality and the size of parts produced by a die can be greatly improved in the stamping proces |
