Shot blasting polishing machine

Abstract

The invention relates to the field of shot blasting polishing, in particular to a shot blasting polishing machine. The shot blasting polishing machine comprises an outer shell assembly, a driving assembly, a transmission assembly and a shot reusing assembly. The driving assembly is arranged on one side of the outer shell assembly. The transmission assembly is arranged above the outer shell assembly. The shot reusing assembly is arranged inside the outer shell assembly. The outer shell assembly comprises a first supporting plate, a second supporting plate, rotating grooves, a first rotary plate, a second rotary plate, a first rotary sleeve, a second rotary sleeve, a feed port, a feed pipe and a connecting plate. The first supporting plate and the second supporting plate are arranged symmetrically. A servo motor in the driving assembly drives a first rotary shaft to rotate. During rotating, the first rotary shaft can drive the second rotary plate to rotate. During rotating, the second rotary plate can drive a to-be-polished pipe sleeved on a semicircular cone clamping block on a plate wall to rotate. Accordingly, the pipe polishing effect of shots sprayed from a shot blasting machineis better.

Description

technical field [0001] The invention relates to the field of shot-peening polishing, in particular to a shot-peening polishing machine. Background technique [0002] The shot peening process uses the high-speed moving shot flow to impact the metal surface to produce a plastic cyclic strain layer on the surface, which leads to favorable changes in the microstructure of the layer and introduces a residual compressive stress field into the surface layer. The microstructure of the surface layer Microstructure and 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 parts are improved, and the fatigue life of parts is improved. Some important components in aircraft, locomotives, automobiles, steam turbines and other machinery, such as springs, shafts, gears, connecting rods, blades, hubs, etc., are subject to c...

Problems solved by technology

[0003] After the existing shot blasting machine is shot peened, the metal shot will be mixed with the powder left by the part of the shot blasted workpiece, and the powder left on the surface of the shot cannot be effectively treated, so that the powder sticks to the projectile. The surface of the projectile, so that when the projectile is used again, the polishing effect of the projectile on the metal part is reduced due to the dust adhering to the surface of the projectile, and when the existing shot blasting machine collects the used projectile for reuse, the projectile needs to be It is time-consuming and labor-intensive to convey the projectiles out of the cylinder of the shot polishing machine, and then to transport the projectiles to the inside of the collecting hopper for reuse
