Description

Technical Field

[0002] At present, workpiece quenching is a heat treatment process, which heats the workpiece to a certain temperature to reduce the temperature difference between the inside and outside of the workpiece and reduce the quenching stress. The workpiece is heated to the critical transformation temperature and maintained for a period of time so that the internal structure of the workpiece reaches a uniform austenitized state. The workpiece is rapidly cooled at a rate greater than the critical cooling rate. Water, oil, brine, etc. are usually used as cooling media. Rapid cooling can form a high-hardness martensitic structure on the surface of the workpiece, thereby improving the hardness, strength, wear resistance and fatigue strength of the workpiece. During the quenching process, the temperature changes suddenly, resulting in a large quenching stress inside the workpiece, which can easily cause the workpiece to bend and deform, and affect the subsequent processing, assembly and use of the workpiece.

Thus, the channel can not only accommodate the workpiece, but also play a role in restraining the workpiece from deforming and bending during the quenching process; in addition, the inclined channel facilitates the workpiece to slide automatically from the higher end to the lower end during loading, and after quenching is completed, the baffle is opened from the upper frame of the frame to allow the workpiece to slide automatically, which not only helps to prevent the workpiece from bending and deforming during the quenching process, but also makes loading and disassembling the workpiece more convenient.
