A quenching device for steel balls after hot rolling

Abstract

The invention discloses a quenching device after hot rolling forming of steel balls. The quenching device after hot rolling forming of the steel balls comprises a box body; the bottom of the inner wall of the box body is fixedly connected with a quenching box; a first fixing plate and a second fixing plate are sequentially and fixedly connected to one side between the opposite two sides of the inner wall of the box body from top to bottom; the top of the first fixing plate is rotationally connected with a spiral feeding roller through a pair of rotating bases; one side of the bottom of the inner wall of the box body is fixedly connected with a first motor; the output shaft end of the first motor is fixedly connected with a speed reducer through a coupler; a rotating device is fixedly connected with the top of the second fixing plate; one side of the rotating device is fixedly connected with a rotating plate through a rotating shaft; a moving device is fixedly connected with the top ofthe inner wall of the box body; and a heating pipe is fixedly connected with the bottom of the moving device. The invention relates to the technical field of steel ball machining. The quenching deviceafter hot rolling forming of the steel balls solves the problem that the steel balls are affected by temperature in the transferring process, meanwhile solves the problem of manual flow distributing,reduces the labor amount and improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of steel ball processing, in particular to a quenching device for steel balls after hot rolling and forming. Background technique [0002] Quenching is a heat treatment process in which steel is heated above the critical temperature, held for a certain period of time, and then cooled at a rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite. Steel ball quenching is a key process in the steel ball manufacturing process. As the quality requirements of steel balls become higher and higher, the hardness of steel balls, especially the uniformity of steel ball hardness, is required to be higher. During the transfer process of the steel balls in the existing quenching device, due to the influence of the ambient temperature, the surface temperature of the steel balls is not uniform.
