Treatment methods to improve the quality of the spring
2022-11-11
The standing treatment of the spring is defined as follows:
1, Setting treatment, setting spring "standing treatment", the compression spring after heat treatment compression to the height of the working limit load or high pressure and height (stretch the spring stretched to the length of the working limit load, torsion spring torsion to the working limit torsion Angle), A process in which one or more short compressions (stretches, twists) are made to stabilize the size of the spring collection.
2, heating setting processing Hot-setting processing, also known as "heating and standing processing". Standing treatment under stable working conditions higher than the spring.
3, strong pressure treatment, the compression spring to the surface of the spring material to produce beneficial residual stress and working stress reverse, in order to improve the bearing capacity of the spring and stabilize its geometric size is a process method.
4, heating pressure treatment, high pressure treatment under higher than the spring working conditions.
5, strong tensile treatment, stretching the spring to the surface of the spring material to produce beneficial working stress reverse residual stress, with high spring bearing capacity and stability of its geometric size is a process method.
6, heating strong pull processing, strong pull processing under the condition of higher than the spring working stability.
7, strong torsion treatment, torsion spring to spring material surface to produce beneficial residual stress and working stress reverse, with high spring bearing capacity and stability of its geometric size is a process method.
8, heating strong torsion treatment, higher than the spring working temperature of the strong torsion treatment.
