Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a processing technology for improving the service life of a pin shaft. Background technique [0002] In the chain industry, pins are widely used and the production batch is large. It is used for shafts that bear both bending moment and torque in rotating work. Since it is a key component, it has high requirements on its strength and toughness. Because the pin requires high hardness and strong wear resistance, etc., the pin requires stricter material and heat treatment process requirements. At present, the processing technology of the pin shaft is relatively common in the prior art, and the treated pin shaft has a large room for improvement in terms of strength and corrosion resistance, and the service life needs to be further enhanced. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a process for improving the service ...
