Description

Technical Field

[0001] The utility model relates to the technical field of quenching equipment, in particular to a soft belt-free quenching machine tool. Background Art

[0002] Quenching is a heat treatment process in metal processing used to improve the hardness and wear resistance of metals. During the quenching process, the metal is heated to a sufficiently high temperature and then cooled rapidly, usually by immersing it in water, oil or other cooling media. This rapid cooling process changes the lattice structure of the metal, thereby hardening it. Quenching machine tools are equipment used to perform quenching processes.

[0003] The existing soft belt of the quenching machine can transmit the power of the motor to the workpiece to realize the rotational movement of the workpiece. When quenching, the soft belt drives the raceway or fixture and other components to rotate, thereby indirectly rotating the workpiece so that the entire workpiece can be evenly heated and quenched. However, the wear and aging of the soft belt require regular replacement, and the replacement of the soft belt requires shutdown for maintenance, which leads to shutdown of the production line and reduced production efficiency, increasing maintenance costs and production costs.
