Abstract

A puncher pin for a stamping die comprises a puncher pin rod body and an overlaying layer on the stamping operation end face of the puncher pin rod body, wherein the surface of the puncher pin rod body except the stamping operation end face of the puncher pin rod body is provided with a magnetron sputtering zinc layer, crystals are fine, uniform and free of pores through the magnetron sputtering zinc layer and passivating treatment conducted on the magnetron sputtering zinc layer, and the resistance to corrosion is good. The obtained zinc layer is pure, acid and alkali corrosion resistance is very good, the protective property of the puncher pin can be remarkably improved, the overlaying layer formed through overlaying treatment conducted on the stamping operation end face of the puncher pin rod body makes the hardness and high temperature resistance of the end of the puncher pin improved obviously, the service life of the puncher pin is prolonged, the puncher pin is easy to repair, and the overlaying layer and copper alloy bonding property can be also good by adopting an overlaying process.

Description

technical field [0001] The invention relates to a punch for a stamping die and a manufacturing method thereof, belonging to the field of stamping dies. Background technique [0002] The punch is subjected to repeated cycle use, and this working condition requires its material to have good strength, high wear resistance, high thermal fatigue resistance, good toughness and high temperature oxidation resistance. The wear resistance, strength and corrosion resistance of traditional material punches are quite poor, resulting in a low service life, and it is easy to damage the stamping components, resulting in unnecessary waste in actual use, which not only increases the labor intensity of the operator, but also The overall cost remains high. Contents of the invention [0003] In order to overcome the above existing defects and difficulties, the present invention provides a punch for a stamping die and a manufacturing method thereof. [0004] A punch for a stamping die, compri...
