Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, and in particular to a thermal stress shot blasting fixture. Background Technology

[0002] As an elastic element widely used in various machines and equipment, the performance and quality of springs directly affect the reliability and stability of related products. Shot blasting is a crucial process in spring manufacturing. Shot blasting significantly improves the surface strength and fatigue life of the spring. The high-speed impact of the shot on the spring surface forms a residual compressive stress layer, which helps to offset some of the tensile stress the spring bears during actual use, thereby effectively delaying the initiation and propagation of cracks and greatly enhancing the spring's fatigue resistance.

[0003] Currently, shot blasting is an important step in the production process of springs. However, existing shot blasting processes are insufficient in terms of processing efficiency, uniformity, and automation, making it difficult to guarantee the consistency of spring quality and resulting in low production efficiency. Therefore, developing a high-efficiency, precise, and automated thermal stress shot blasting fixture is of great practical significance. Utility Model Content
