Treatment of High Temperature Springs Standard Process

- Mar 09, 2017 -

1. Set the processing set, also known as "legislation processing". Compresses the heat-treated compression spring to the height or pressure at the working limit load (the length of the tension spring stretched to the working limit load, the torsion spring twists to the working limit twist angle), one or more short- Stretching, twisting) to achieve a stable spring geometry for the main purpose of a process.

2. Heating set processing Hot-setting, also known as "heating up processing." In the spring above the operating temperature of the initial treatment.

3. Compressive [Compressive] pre stressing The compressive spring is compressed to the surface of the spring material to produce a useful residual stress in the opposite direction to the working stress in order to achieve a spring loading capability and a stable geometric dimension.
