In the auto parts market, the safety requirements of the auto parts are improved, so the automobile spring manufacturers also continue to improve the production quality of the spring according to the specifications of the market, especially in the case of stress tempering. This piece, from the previous fire to the special material to the oven and then roast the oven, this series of changes have also witnessed the spring on the requirements of the tempering rising, today Jianzhen spring on the stress to the amount of stress to introduce the amount of heat , Hope that we can seriously view.
Spring steel wire made of spring, to go through the stress-tempering process, in general, to reduce the diameter of the spring, the total number of laps to increase. Diameter of the amount of contraction and the rotation ratio, the greater the rotation ratio, the greater the amount of contraction. Therefore, before the mass production to carry out the first sample, the sample can be determined after batch production, with the high-stress spring mass production, oil tempering alloy spring material is widely used, but there is no empirical formula in this regard, according to My company for many years experience in spring production and found that the spring to stress the amount of static shock shrinkage there is a certain law, the data is now regression analysis of the following empirical formula: △ D = 3.188 × 10-6 × C × D × T
