Description

Technical Field

[0001] The utility model relates to the technical field of gear forging blank processing equipment, in particular to gear forging blank quenching and tempering processing equipment. Background Art

[0002] Gear forging blank refers to the gear raw material made by forging process, which is usually used to manufacture gear parts. Gear forging blank quenching and tempering equipment is mainly used to quench and temper the gear forging blank to improve its comprehensive mechanical properties. Quenching and tempering treatment is a heat treatment process, which heats the gear forging blank to a certain temperature, then keeps it warm, and finally cools it rapidly, thereby changing its microstructure and improving its hardness and strength.

[0003] During the use of the existing gear forging quenching and tempering treatment equipment, it is necessary to use coolant to soak the heated gear forging for rapid cooling. After the coolant inside the treatment equipment is constantly in contact with the high-temperature gear forging, the temperature of the coolant is likely to gradually increase. The increase in the coolant temperature is likely to reduce the cooling speed of the coolant soaking the high-temperature gear forging, thereby reducing the working efficiency of the treatment equipment. To this end, we provide a gear forging quenching and tempering treatment equipment to solve the above problems. Utility Model Content
