Heat Treatment Equipment: Gear shaft high frequency quenching machine quenching process

Gear shaft is a shaft and gear synthesis, is the support of rotating parts. Often used in cars, buses, excavators and other mining equipment. It plays an important role in the operation of mechanical equipment. In the operation of equipment, the gear bearing is required to be subjected to huge friction force, so it is required to have a strong hardness, wear resistance and a long service life. High-frequency quenching machine is widely used in this industry, in the quenching process, the effect is very good.

The surface quenching of gear shaft by high frequency quenching machine is mainly realized by the combination of rapid heating and immediate quenching cooling. The operation is not practicable and local overheating and melting often occur. Due to the different structure of gear shaft, it is difficult to use mechanical automatic method for flame surface quenching in production, and most of them are operated manually. The gear shaft and other quenching parts are quenched one by one by means of circular inductor. Using rapid heating in the process of hardening the surface quickly reach the temperature of quenching, range and quantity of heat to center the rapidly cooling, it can only make the gear shaft surface is hardened to martensite, and the center is still not quenching organization, after quenching, the surface will have a layer of hardening layer, about 2-3 mm, just because of the hardening layer, make gear shaft hardness and wear resistance is greatly increased. The specific application should be determined according to the actual diameter of the gear shaft.

The high frequency quenching machine USES the numerical control system and the import component. Strictly check each device, do not have a detail, to avoid the instability of the equipment. By adjusting the speed and temperature of workpiece moving, automatic continuous quenching treatment of gear shaft can be realized. Fast quenching speed and short quenching time can effectively avoid oxidation and decarburization of gear shaft and ensure the quenching effect of gear shaft. Advanced high-frequency quenching machine replaced the old quenching heating equipment, environmental protection and energy saving, energy saving, energy saving, improve production efficiency, reduce labor costs.
