Description

technical field

[0001] The invention relates to the field of parts heat treatment, in particular to a quenching device for pulley parts. Background technique

[0002] Quenching is to heat a metal workpiece to a certain temperature, and then quickly immerse it in water or oil to cool it down, thereby increasing the hardness of the metal part.

[0003] At present, the rope groove quenching on the surface of pulley parts can only be carried out with special pulley quenching equipment. The special pulley quenching equipment includes the inner ring turntable, the inner ring lifting device, the outer ring heating device and the cooling liquid tank arranged at the bottom of the inner ring turntable, the inner ring turntable is arranged on the top of the inner ring lifting device, and the outer ring heating device surrounds the inner ring Turntable arrangement. The outer ring heating device can be heated by flame or electromagnetic induction, and the outer ring heating device is f...
