4 points to reduce the deformation of compression spring

During the normal use of the compression spring, the deformation occurs due to various reasons. The elastic force of the deformed compression spring will drop, and the free height will also drop, which will affect the normal operation of the mechanical parts, and even lead to the damage of the entire equipment in serious cases.

How to avoid compression spring deformation

1. Reasonable design

The working stroke conforms to the elastic range of the compression spring to avoid the deformation of the spring and the reduction of the free height in use.

2. Material selection

In the selection of materials, it is necessary to avoid selecting inferior materials with uneven distribution of material components or unqualified content of certain elements to prevent deformation or fracture of springs in actual use.
Select the appropriate compression spring material according to the actual working conditions, for example, oil-quenched steel wire is more suitable for dynamic load, while the spring steel represented by piano steel wire is more suitable for static load. Stainless steel or special alloy is more suitable for use at different temperatures. Selecting the wrong material of spring will lead to spring deformation or fracture.

3. Perpendicularity difference

When working, the stress point is not in the center. Long-term use of the spring is prone to tilt, lower working height, fracture, etc.

4. Processing technology

The service life of the spring is affected by factors such as processing accuracy, tempering temperature and duration.
