Description

Technical Field

[0001] The invention relates to the technical field of mechanical casting processing, and in particular to a quenching device and method for mechanical casting processing. Background Art

[0002] The purpose of quenching is to transform the supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then temper it at different temperatures to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the steel, so as to meet the different use requirements of various mechanical parts and tools. Quenching can also be used to meet the special physical and chemical properties of some special steels such as ferromagnetism and corrosion resistance.

[0003] Quenching is a metal heat treatment process that heats the metal workpiece to a certain appropriate temperature and keeps it for a period of time, and then immerses it in a quenching medium for rapid cooling. Common quenching media include salt water, water, mineral oil, air, etc. Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various tools, molds, measuring tools and parts that require surface wear resistance.

[0004] When the existing quenching equipment for mechanical casting processing sinks the mechanical casting into the quenching pool for quenching, the high temperature of the casting quickly causes the quenching medium around the casting to boil. Due to the effect of the high temperature rising, the cooling rate of the upper part of the casting is much lower than that of the lower part. The lack of heat equalization measures causes different internal stresses in the casting itself, causing the casting to twist, deform, or even crack. Summary of the invention
