Embodiment 1
[0017] A heat treatment process for a 65Mn spring washer. The heat treatment process includes blanking, electric spark drilling, wire cutting, fitter correction, heat treatment, performance testing and surface treatment. The heat treatment includes quenching and tempering. During the quenching of heat treatment, the 65Mn spring washer is preheated first, and the preheating refers to putting the 65Mn spring washer into the preheated quenching tool; firstly, the temperature of the quenching furnace is raised to 820°C, Then add charcoal into the quenching furnace, the charcoal is pulverized before being added into the quenching furnace, the particle size range is 200 mesh, the amount of charcoal added is 8kg, and the temperature is kept at a constant temperature for 10 minutes; Put the 65Mn spring washer into the quenching tool, and quench it immediately after keeping it warm for 10 minutes, and the quenching and holding time is 5 minutes; before putting the 65Mn spring washer int...

[0021] A heat treatment process for a 65Mn spring washer. The heat treatment process includes blanking, electric spark drilling, wire cutting, fitter correction, heat treatment, performance testing and surface treatment. The heat treatment includes quenching and tempering. During quenching of heat treatment, the 65Mn spring washer should be preheated first. The preheating refers to putting the 65Mn spring washer into the preheated quenching tool; Charcoal, charcoal is crushed before adding to the quenching furnace, the particle size range is 300 mesh, the amount of charcoal added is 12kg, and the temperature is kept at a constant temperature for 15 minutes. In the quenching tool, quench immediately after holding for 15 minutes, and the quenching and holding time is 10 minutes; before the 65Mn spring washer is put into the quenching tool, apply anti-oxidation and decarburization paint on the surface of the 65Mn spring washer. After quenching, oil-cool the 65Mn spring washer unt...
