Shot blasting polishing machine

Abstract

The invention relates to the field of metal surface treatment, in particular to a shot blasting polishing machine which comprises a shot blasting polishing machine shell, a material storage barrel is arranged at the upper end of the shot blasting polishing machine shell, a first material conveying pipe is fixedly connected to the lower surface of the material storage barrel, and the first material conveying pipe communicates with the material storage barrel; the lower end of the first conveying pipe penetrates through the upper end of the shot blasting polishing machine shell and extends into the shot blasting polishing machine shell, the lower end of the first conveying pipe is rotationally connected with a shot blasting disc, and an output shaft of the high-pressure fan is fixedly connected with the lower surface of the shot blasting disc; and a supporting net is fixedly connected to the position, located at the lower end of the first supporting rod, of the inner wall of the shot blasting polishing machine shell, a workbench is fixedly connected to the position, located at the left end of the high-pressure fan, of the upper end of the supporting net, and a cleaning and sorting unit is arranged at the lower end of the supporting net. And impurities and shots are mixed together, so that the follow-up shots are not easy to recycle.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a shot blasting machine. Background technique [0002] Shot peening is a surface strengthening process widely used in factories, that is, a cold working process that bombards the surface of the workpiece with pellets and implants residual compressive stress to improve the fatigue strength of the workpiece. It is widely used to improve the mechanical strength, wear resistance, fatigue resistance and corrosion resistance of parts; the advantages of shot peening are simple equipment, low cost, not limited by the shape and position of the workpiece, and easy operation. The disadvantage is that the working environment is poor. The unit output is low, and the efficiency is lower than that of shot blasting. The types of shot peening include steel shot, cast iron shot, glass shot, ceramic shot and so on. [0003] However, after the workpiece is shot peened, the shot will be damag...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a shot-peening polishing machine, which mainly solves the problem that after the workpiece is shot-peened and polished, the projectile will be damaged, impurities and projectiles will be mixed together, and it is not easy to recycle the follow-up projectile.
