1. Yield strength，There is a certain relationship between the yield strength of the material and the fatigue limit. Generally speaking, the higher the yield strength of the material, the higher the fatigue strength. Therefore, in order to improve the fatigue strength of the spring, try to increase the yield strength of the spring material, or use A material with a high ratio of yield strength to tensile strength. For the same material

1. Piano wire: (Piano wire)It is toughened with piano steel wire, and with strong wire drawing processing, it gives good dimensional accuracy, good surface skin, and high mechanical properties. Toughening is to continuously heat high carbon steel wire at a temperature above the deformation point for about 500 It is cooled in

​A spring is a part that can produce greater elastic deformation under load.1. The type of spring The type of spring The type of spring The type of springAccording to different loads, springs can be divided into extension springs,

​In recent years, the surface finishing (finishing) treatment of springs has also been recognized by spring designers.The finishing (finishing) process is to put the spring directly into the inclined centrifugal, spiral vibrating, vortex and other series of finishing machines, and add an appropriate amount of abrasives, abrasives and water for finishing. Normally, it takes about 20~30min.

​Special-shaped springs include circlips, extension springs, and torsion springs. Generalized special-shaped springs also include serpentine springs, wave springs, rod springs and other springs with complex shapes. Special-shaped springs are basic parts with a wide range of applications and various varieties in automobiles, motorcycles, electrical appliances, and instrument products. Their quality and life span directly affect the performance of the
