Efficient shot blasting equipment for removing rust and burrs of steel part

Abstract

The invention discloses efficient shot blasting equipment for removing rust and burrs of a steel part. The efficient shot blasting equipment for removing the rust and the burrs of the steel part comprises a shot blasting box and a pneumatic mechanism arranged on the right side of the shot blasting box, wherein a working cavity is formed in the shot blasting box. According to the efficient shot blasting equipment for removing the rust and the burrs of the steel part provided by the invention, a mode of directly adding dry ice fragment spraying on the rear side of a metal ball jet flow is used,rust removal and burr removal are integrated into one procedure, and traditional cleaning, drying and other procedures are not needed after dry ice spraying, so that the steps are greatly simplified,dry ice can be directly gasified after being used, and whether residues exist or not does not need to be manually detected; coarse and fine particles are separated in a vibration mode in subsequent separation equipment, so that the reuse rate of metal balls in a shot blasting machine is increased, rust, burrs and dust are collected in a unified mode, the cleaning cost is reduced, and the working environment quality is improved; and meanwhile, automation of the treatment process is achieved, so that the treatment efficiency is greatly improved, and labor force is saved.

Description

technical field [0001] The invention relates to a high-efficiency shot blasting equipment for derusting and deburring steel parts, and mainly relates to the technical field of derusting steel parts. Background technique [0002] The shot blasting machine is different from the domestic sand blasting machine. Its process principle is to use the impact of the high-speed moving shot flow on the metal surface to generate a plastic cyclic strain layer on the surface, which leads to favorable changes in the microstructure of the layer and Introduce the residual compressive stress field into the surface layer. The microstructure of the surface layer and the residual compressive stress field are two strengthening factors to improve the fatigue fracture and stress corrosion (hydrogen embrittlement) fracture resistance of metal parts. As a result, the reliability and durability of the parts are improved. Sex gain is improved; [0003] At present, the shot blasting machine used for der...

AI Technical Summary

Problems solved by technology

[0003] At present, the shot blasting machine used for derusting and deburring is mainly used when the casting factory is transported to the processing plant. The castings are prone to rust during transportation, as well as the burrs and shot peening produced by the casting itself or after cutting. The machine is used to deal with these. It mainly uses spraying small steel balls to remove rust and repair the surface of steel parts. In addition to manual grinding, the main method of deburring is to use plastic balls to clean burrs. This method is efficient and does not require It needs to be manually polished in a place with harsh working environment, but this process is carried out in two steps, that is, after shot peening. The increase in the process also means the increase in cost, and some plastic debris will remain on the workpiece after plastic injection The surface is affected in the subsequent processing and assembly process. Generally, manual detection and manual processing are required after plastic injection. In actual operation, the labor cost is high, time-consuming, laborious and inefficient, and the automatic transmission is not high. Aiming at the above shortcomings, the present invention has carried out Improve
