Device for polishing and impurity removal of steel balls

Abstract

The invention discloses a device for polishing and impurity removal of steel balls. The device comprises a bracket, an external box body, an internal barrel body and a sieve plate, wherein the external box body is arranged on the bracket; the internal barrel body and the sieve plate are arranged in the external box body; a polishing rod is arranged in the inner axial direction of the internal barrel body; bulges are distributed on the polishing rod; through holes are distributed in the side walls of the internal barrel body; an elastic connecting piece is arranged at the lower end of the sieve plate; a material outlet is formed in the part, near the lower end of the sieve plate, of the external box body. Steel balls to be polished are added into the internal barrel body; the internal barrel body is driven to rotate through a driving device; the steel balls collide and rub with the bulges on the polishing rod; powdered scrap generated during the steel ball polishing process drops from the through holes; when the steel balls are polished, the internal barrel body is rotated to enable a material inlet-outlet to face down; a material inlet-outlet door is opened and the sieve plate vibrates up and down through the elastic connecting piece, so that the powdered scrap on the surfaces of the steel balls drops under collision. According to the device, the powdered scrap generated during the steel ball polishing can be timely separated from the steel balls and the impurity on the surfaces of the steel balls can be immediately removed after steel ball polishing is finished.

Description

technical field [0001] The invention relates to the technical field of steel ball production and processing, in particular to a steel ball grinding and impurity removal device. Background technique [0002] Steel ball is a general term for steel balls, steel segments and special-shaped grinding bodies. From the shape, it can be divided into perfect round ball, capsule ball, ellipse ball, yin and yang ball, hollow ball, multi-faceted ball, multi-missing ball and so on. Steel ball production methods generally include forging, rolling, semi-solid forming and casting. Due to the history and some special conditions of use and the comprehensive environment and background of the mineral processing industry, forging and rolling balls occupy a considerable proportion in these industries. Semi-solid molding has the characteristics of unconventional casting, which cannot be explained clearly by simple die-casting. It has attracted people's attention for its excellent performance form...

Problems solved by technology

However, the inner wall of the ordinary grinding box is a simple arc surface, the grinding area is small, and the grinding efficiency is low; in addition, the powder chips produced by grinding cannot be discharged in time, and the powder chips need to be separated after the steel balls are polished and poured out. Afterwards, the surface of the steel ball is stained with powder, which needs to be further removed, which increases the labor process
