Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment equipment, in particular to an expansion mechanism for a 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.
