Spring stabilization
- Jan 11, 2018 -

    In the ideal case, the spring should conform to Hooke's law, that is, there is a linear relationship between stress and strain in the elastic range. Elastic incomplete or anelasticity is due to the actual spring steel is heterogeneous polycrystalline material, there must be composition, organization, elasticity and other inconsistencies in the elastic range of stress and strain deviate from the linear relationship. The resulting elastic after-effects, elastic lag, stress relaxation, elastic modulus and other phenomena. After the spring tempering stabilization can reduce the flexibility of the incompleteness of the stability of the general treatment in the field as the legislation set.

  Set the processing of the compression spring, the spring is compressed to the maximum working height or tightness and the number of times; for the tensile spring, the spring length is pulled to the working limit length several times; for the torsion spring, the spring is twisted to the working direction Work limit twist angle several times. After this effect 7 times, the spring will tend to be stable, on-site operation, generally take 3-5 times.

  Strong pressure treatment also has a stabilizing effect on the spring.

  After the spring set the legislature, after the intense pressure to reduce the free height. In order to make the spring reach the stipulated free height, the winding height during the coil spring should leave the deformation amount except the free height. This height is called the prefabricated height. Because the legislation and the impact of pressure processing more factors, so the deformation can not be calculated very accurately.
