Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment equipment, in particular to a chain heat treatment quenching cooling system. Background Art

[0002] Chains are generally metal links or rings, and are mostly used for mechanical transmission and traction. They are chain-shaped objects used to block traffic passages, such as chains used for mechanical transmission in streets, rivers or at the entrances of harbors. In the production process of chains, in order to give the chains better comprehensive mechanical properties, they generally need to be quenched. The chain is quenched by heating it to a certain appropriate temperature and maintaining it for a period of time, and then immersed in a quenching medium for rapid cooling. The chain is then tempered at different temperatures to greatly improve its strength.

[0003] In the existing chain heat treatment quenching cooling device, during the chain quenching process, the chain is placed in a hanging basket, and then the hanging basket is placed in a cooling pool for centralized cooling. However, the internal temperature of the accumulated chain is difficult to be effectively cooled, which will affect the quality of the chain. In order to improve the hardness of the chain core and surface, the workpiece needs to be cooled secondary. Most of the current heat treatment quenching cooling devices only cool the chain once.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A chain heat treatment quenching cooling system comprises a cooling pool, a support frame is fixedly connected to the side wall of the cooling pool, both ends of the support frame are rotatably connected to a rotating shaft, a plurality of sprocket wheels are fixedly sleeved at equal distances on the outer walls of the two rotating shafts, a chain is meshingly connected between the two sprocket wheels, the ends of the two rotating shafts are fixedly sleeved with synchronous wheels, a transmission belt is sleeved between the two synchronous wheels, and the end of one rotating shaft is fixedly connected to the output end of a servo motor.
