A kind of automatic sorting heat treatment device about forging steel ball was designed for a company in Hebei, which is working for the manufacturing technique of the heat treatment about manual sorting forging steel ball. The device, which overall structure was disc barrel, was a combination of the technology about machine, electricity and gas. Whats more, the round rails were set up, the space of which was variable. The rotary components, which were installed on the fixed plate parts, could realize the adjustable speed of intermittent rotation with the impulse of the power plant. After the ball going into the rails, it would become cool with the rotation of the rotary parts, and there were 16 intermittent rotating positions with round hole on the disc. It was equipped with temperature measuring equipment for realtime monitoring to realize the ball down combined with the pneumatic device of temperature control equipment, which could control the action of the activity guide rails. The whole device could effectively realize automatic control, automatic sorting for shunt quenching temperature forging steel ball to the heat treatment quenching pool and not suitable for low temperature heating and quenching temperature of steel ball device. The quality problem is solved that the surface hardness of the steel ball caused by the uncertainty of the original production process is not uniform and the instability of the steel ball surface is not uniform, and the production cost is reduced and the production efficiency is improved.
