Abstract
The invention relates to an air cooler for quenching, which is equipped with a bracket, a speed-regulating motor, a gearbox, a tooth plate, a chain, an iron cabinet box, a transmission belt, an axial fan, a bellows, an air outlet, a triangle belt, a fixed shaft, The fixed bracket is characterized in that: the base is equipped with a rectangular iron box, and the two ends of the iron box are connected, the axial flow fan is installed on the rectangular iron box, the lower end of the axial flow fan is equipped with a bellows, and two front and rear outlets are installed on the bellows. The air hole and the fixed shaft are installed on the base with a fixed bracket. The speed-adjusting motor and the gearbox are installed on the base. To cooperate, the transmission belt is installed on the two cranksets. The invention adopts air cooling for quenching, the wind speed fluctuation range is small, the surface state of the workpiece is not sensitive, the quality of the quenched workpiece is guaranteed, and it has the advantages of simple structure, economical and practical, low workpiece reject rate, no environmental pollution, and safe use.
Description
technical field [0001] The invention relates to a quenching device for forgings, in particular to an air cooler for quenching. Background technique [0002] We know that at present, there are many heat treatment and quenching methods, and oil quenching is one of the commonly used methods. However, this quenching method often makes the state of the forging unstable, resulting in insufficient or excessive heat treatment, and the oil injection time is too long. It is easy to cause cracking of forgings Or the hardness is not enough, resulting in a high scrap rate. At the same time, a large amount of oil fumes are produced during quenching, which is very unfavorable to the environment and human health. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above methods and technologies, and provide an air cooler for quenching that uses air to quench forgings, improve the surface quality of workpiec...
