High precision of the small spring is how to make! Know a little about springs: The structure of the spring is more mature, in order to ensure its characteristics of the most principle is to choose the way of spring, raw materials, clear specification parameters and thermal engineering academy of these general conditions of the larger flexure of the spring is 300,000 times, when the number of applications exceeds the larger flexure, the cross section will produce more than the rated stress and eventually lead to damage. In addition, because of the close compression length, a reasonable part of the spring winding is gradually compressed, the spring constant expands, the load diagram rises, so it will produce high stress, and the spring manufacturer will eventually lead to damage. In addition, the piano steel wire, hard steel wire forming to press the spring coil should be low-temperature quenching so as to adjust the original stress in many ways, spring customized manufacturers such as stainless steel wire when the original stress is reduced by 15%; After forming the implementation of low-temperature quenching steel wire, hard steel wire and other steel wire is relatively reduced by 20%~ 35% spring winding should be in a made of billet wound system, fixed at both ends after heat treatment and other heat treatment to improve the elasticity of the quenching to remove the residual stress, and finally surface plating and polishing.
