Compression spring hardened two methods

Compression spring ends is open, closed or raoping, grinding flat, its shape is of diversity, under external load contraction deformation, translate into performance. Compression spring can be used in many fields, such as electronics, computers, cars, compressors, and other industries, can highlight the role of it. Manufacturers add hard two methods to compression spring compression spring is a composed of spiral line geometry of hardware fittings, so more difficult than graphic hardware accessories for stiffening and strengthening operation. In addition, strict control of the stiffening effect of the section, compression spring to resist decompression after spring use fully the fatigue and fracture resistance. Pressure spring by shot peening and hardening heat treatment. Blasting and hard spring pressure processing, it needs to handle multiple pressure springs, can be through the pressure spring belt conveyor to the blasting room alone, blasting city is equipped with a set of parallel bar, at the same time, strengthen the rolling drum, compression. Spring side forward rotation, but by allowing high-speed rotating way makes the projectile circulation overvoltage between the spiral spring, hit the surface of the metal ring, the good are important parts of the pressure spring stress *, shot peening is one of the S * better strengthening method. Spring tension, high stress fatigue life in the spring after an appropriate shot peening can improve more than four times. After compression spring hardened, can improve the effect of the use of the spring, especially in the spring in use after a period of time, all need to add hard and continue to use, effectively prolong the service life of the spring.
