Description

Quenching device for metal casting machining Technical Field The utility model relates to the technical field of quenching, in particular to a metal casting machining quenching device. Background Quenching of metal castings is an important heat treatment process aimed at improving the hardness, strength, wear resistance and fatigue life of the castings. When the metal casting is quenched, the quenching method is divided into immersion type and spray type according to the quenching mode, wherein the spray type quenching has the advantage of high cooling speed, and is suitable for workpieces with high-hardness surfaces. When the metal castings are subjected to spray quenching, the rollers are utilized to carry out conveying work of the castings, and when the castings pass through the spray structure, spray quenching is performed. However, in the existing spray quenching device, only the upper spray part is used for spraying the castings, the lower part of the castings is not provided with a spray structure, so that the castings are unevenly quenched up and down, the uniform cooling of the castings is further affected, the rollers cannot be subjected to spray cooling protection when the rollers are used for conveying the castings, the rollers are easily damaged after being contacted with the high-temperature castings for a long time, and the use cost is further increased. Disclosure of utility model The utility model mainly aims to provide a metal casting processing quenching device which can effectively solve the problems in the background technology.
