Shot peening machine

Abstract

The invention belongs to the technical field of shot peening equipment, in particular to a shot peening machine. The shot peening machine comprises a shot peening box, an operation unit, a working unit and a controller, wherein the controller is used for controlling the shot peening machine to work; the operation unit comprises a groove-shaped upper supporting plate, a groove-shaped lower supporting plate, a sliding block, an installation block, a connecting shaft, a forward and reverse rotation motor, an elastic first lead screw and a fixing block; and the working unit comprises a first motor, a first shaft and a first rod. Under the action of the forward and reverse rotation motor, the fixing block passes through the shot peening box twice, so that the shot peening times of the shot peening box on a tubular object are increased, and the shot peening effect of the tubular object is improved; and meanwhile, when the working unit penetrates through the shot peening box, the first motoris used for driving the first shaft to rotate, so that the tubular object is subjected to shot peening treatment without dead corners, the dead corners, which are not subjected to shot peening treatment and need to be treated again in the later period, of the tubular object are reduced, the shot peening cost is reduced, and the practicability of the shot peening machine is improved.

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...
