Abstract

The invention discloses a drum type quenching machine composed of frame and drum, which is characterized in: the frame is equipped with a drum bracket by a rotating shaft, the drum bracket being equipped with V-shaped riding wheel group at least consisting of front and rear V-shaped riding wheels and gear riding wheel group at least consisting of front and rear gears; the drum outer wall is equipped with V-shaped rims riding inside of the V-shaped riding wheel group and transmission rims riding on the gear riding wheel and engage with each other; the drum inner wall is fixed with screw blades; the drum bracket is equipped with V-shaped wheel sleeves outside of the V-shape rim of the drum; one end of the drum bracket is connected with jack-up air cylinder or oil cylinder at the lower part. The drum quenching machine meets the norms and technology requirements of current cast ball quenching treatment, is successfully used in wear-resisting cast ball industry, the quenched casting has even hardness and reaches the oil quenching norm. The uniformity of hardness of batch processing is better than that of oil quenching, completely avoiding the appearance of quenching crack.

Description

technical field [0001] The invention relates to a metal heat treatment equipment. It is mainly used for quenching treatment equipment of grinding media wear-resistant casting balls and segments of powder engineering. Background technique [0002] The traditional quenching of casting balls and segmental workpieces has always used the wind quenching mechanical shaker, the stirring method of the oil quenching mechanical oil pool, supplemented by mist supply or air supply device, which is the second medium or called dual medium, single wind or mist quenching The methods are all limited by the process of air quenching mechanical shaker equipment, so there are many shortcomings after quenching the workpiece. For example, the hardness of the material workpiece after quenching is significantly reduced by 2-4HRC compared with oil quenching, and the hardness of the same batch of workpieces is uneven, with a difference of up to 7-8HRC, even the phenomenon of hardening impermeability, ...
