a shot blasting machine

Abstract

The invention belongs to the technical field of shot blasting equipment, specifically a shot blasting machine; including a shot blasting box, an operating unit, a working unit and a controller; the controller is used to control the work of the shot blasting machine; the operating unit includes a groove The upper support plate, the grooved lower support plate, the slider, the installation block, the connecting shaft, the forward and reverse motor, the elastic No. 1 screw and the fixed block; the working unit includes the No. 1 motor, the No. 1 shaft and the No. 1 rod ;Through the action of the forward and reverse motor, the fixed block passes through the shot blasting box twice, which increases the number of shot blasting of the tubular object by the shot blasting box and improves the shot peening effect of the tubular object; When using the No. 1 motor to drive the No. 1 shaft to rotate, so that the tubular objects can be shot blasted without dead ends, which reduces the need for reprocessing of the dead ends of the tubular objects that have not been shot peened in the later stage, reduces the cost of shot blasting, and improves The practicability of the shot blasting machine.

Description

technical field [0001] The invention belongs to the technical field of shot blasting equipment, in particular to a shot blasting machine. 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 The residual compressive stress field is introduced 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. At the same time, the oxide scale and dirt on the metal surface will be taken away during the impact of the high-speed projectile flow on t...
