Embodiment 1

[0052] see Figure 1-10 , a self-removing slag type bearing grinding process, comprising the following steps:

[0053] S1. Upsetting ball blanks: Upsetting single-section bearing steel wire segments into steel ball blanks through a cold heading machine;

[0054] S2. Light ball making circle: Put the obtained steel ball blank into the light ball machine, and repeatedly process the steel ball blank, remove the outer ring belt and two poles on the surface, and obtain a thick round steel ball;

[0055] S3. Quantification of soft balls: transport the thick round steel balls into the soft ball machine body 1, and make them grind the thick round steel balls to the specified size through the cooperation of the hemispherical slag removal grinding tank 201 and the hemispherical slag removal quantitative tank 301, Remove the small burrs on the wall surface of the thick round steel ball, and perform self-removing slag treatment through the action of the fixed grinding disc branch arc tub...

Embodiment 2

[0063] see Figure 1-10 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to Figure 2-4 , a self-removing slag-type bearing grinding device, comprising a soft ball machine body 1, a fixed grinding disc 2 for guiding materials and a quantitative movable grinding disc 3 positioned on the upper side of the fixed grinding disc 2 are installed on the main body 1 of the soft ball machine, and the upper end of the fixed grinding disc 2 is opened There is a hemispherical slag-removing grinding tank 201, and the fixed grinding disc 2 of the guide material is fixedly connected with a fixed grinding disc branch arc tube 4 matching with the hemispherical slag-removing grinding tank 201, and the outer end of the fixed grinding disc branch ar...

Embodiment 3

[0066] see Figure 1-10 , wherein the same or corresponding components as those in Embodiment 2 use the corresponding reference numerals as in Embodiment 2, and for the sake of simplicity, only the differences from Embodiment 2 are described below. The difference between this embodiment 3 and embodiment 2 is: please refer to Figure 5 A residual liquid guide groove located at the lower side of the hemispherical slag removal grinding groove 201 is opened in the fixed grinding table 2 of the material guide, and a residual liquid concentration chamber 202 is provided on the lower side of the fixed grinding table 2, and the lower inner wall of the residual liquid guide groove is fixedly connected with a drainage arc tube 6 , the drainage arc tube 6 is fixedly connected with a plurality of drainage branch pipes 601 connected with it, and the lower end of the drainage branch pipe 601 extends into the raffinate concentration chamber 202 and is connected with the raffinate concentrati...

Abstract

The invention discloses a self-removing slag-type bearing grinding process and a grinding device thereof, belonging to the field of bearing processing, a self-removing slag-type bearing grinding process and a grinding device thereof, upsetting ball blanks; light balls making circles; soft balls quantification; Intensified heat treatment; fine grinding; polishing and anti-rust; assembly and debugging, the steel balls can be self-removing slag when the steel balls are quantitatively ground on the body of the soft ball machine by acting on the branch arc tube of the fixed grinding disc and the branch ring tube of the moving grinding disc, so that the soft The ball machine body forms a process of removing grinding residues while quantitatively grinding, which effectively improves the timeliness of removing slag from the soft ball machine body, reduces the impact of grinding residues on the size and roundness of the steel balls, and improves the soft ball machine body. The quantitative accuracy improves the quality of steel balls, effectively avoids irreparable quality problems, reduces the loss rate of steel balls, reduces the cost of bearing processing, and improves its economic benefits.

Description

technical field [0001] The invention relates to the field of bearing processing, and more specifically relates to a self-removing slag type bearing grinding process and a grinding device thereof. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings are most widely used as rolling bearings, of which deep groove ball bearings are the most representative rolling bearings. Compared with other types of bearings with the same size, this type of bearing has a small friction coefficient, high limit speed, simple structure, low manufacturing cost, high precision, no need for frequent maintenance, and has a wide range of sizes and various forms. It is the most widely used type bearings. [0003] Deep groove ball bearings mainly bear radial loads and can also bear certain axial loads....
