Description

Quenching mechanism for metal parts Technical Field The utility model belongs to the technical field of quenching equipment, and particularly relates to a metal part quenching mechanism. Background The metal quenching is a heat treatment process for improving the hardness and strength of the metal by rapid cooling, and the process comprises the steps of heating the metal to a temperature above a critical temperature (usually 750-1300 ℃), preserving heat to austenitize the metal, then rapidly immersing the metal in quenching media such as water, oil or polymer, and the like, wherein the rapid cooling inhibits the transformation from austenite to pearlite to promote the formation of a high-hardness martensitic structure, the quenched metal has obviously improved hardness but increased brittleness, and is often matched with tempering treatment to adjust the balance of toughness and internal stress, so that the metal is widely applied to the strengthening treatment of key mechanical parts such as cutters, molds, gears and the like, and is a core process for improving the wear resistance and the service life.
