Spring roller conveyor shot peening machine

Spring strengthening shot blasting machine is a kind of equipment for spring surface treatment. Shot blasting strengthening is a specially designed technology to improve the fatigue strength of components subjected to alternating stress. Cyclic plastic strain layer is produced on the surface of spring by the impact of high-speed steel shot flow on the spring surface, which leads to favorable changes in the microstructures of the spring surface and the introduction of residual compressive stress field into the surface. Thus, the fatigue fracture and stress corrosion fracture resistance of the spring can be improved, and the reliability and durability of the spring can be improved.
