Buckling and placing tool for steel ball heat treatment applied to bearing assembly

Abstract

The invention provides a buckling and placing tool for steel ball heat treatment applied to bearing assembly. The buckling and placing tool comprises a base plate and a pressing seat, wherein the baseplate is of a circular plate structure, and a stand column of a large circular cavity cylinder structure is welded to the middle of the base plate in a perpendicular mode; a large spring is further welded in the cylindrical cavity of the stand column in a perpendicular mode, and a falling plate is further welded to the top end of the large spring; the pressing seat is a rectangular shell piece and is welded to the top surface of the falling plate in an inverted buckling mode, and an ejecting and stretching rod is further welded to the outer end of the pressing seat; and each steel ball is inrotation, so that the heat treatment effect is better. The overall structure of the device is simple, and the end of each station spring tube is provided with an elastic limiting mechanism, so that the loaded steel balls are not prone to disengagement due to the influence of vibration, and the heat treatment mode in which the steel balls can rotate in the spring tube cavities to a certain degree can improve the heat treatment speed of the steel balls.

Description

technical field [0001] The invention belongs to the technical field of steel ball heat treatment, and more specifically relates to a buckle-and-release tool for steel ball heat treatment used in bearing assembly. Background technique [0002] Heat treatment refers to a metal thermal processing process in which the chemical composition and structure of the surface or interior of the material is changed by means of heating, heat preservation and cooling in the solid state to obtain the required properties. The steel balls that constitute the bearing are processed before assembly. All need to be heat treated to make their internal structure change and improve the strength, so as to improve the service life of the final assembled bearing. [0003] In the existing heat treatment process of steel balls, steel balls lack reasonable heat treatment process tooling. When they are placed in heat treatment furnaces or other heat treatment environments for heat treatment, they are placed...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a buckle-and-release tooling for steel ball heat treatment used in bearing assembly, to solve the problem that steel balls lack reasonable heat treatment process tooling in the existing steel ball heat treatment process. When heat treatment is carried out in a furnace or other heat treatment environment, they are usually placed by a drag bucket or a clamping fixing mechanism. When they are heat treated in a heat treatment environment, they are mostly in a static state. Accepting the effect of heat treatment, the speed of internal tissue change will be lower than the speed of structural tissue change in other regions
