Spring not in place and cause of failure

Category:


【Summary Description】In practical work, we often encounter situations where springs cannot push moving objects to the set position, which means that the calculated free length of the spring is shortened.

In practical work, we often encounter situations where springs cannot push moving objects to the set position, which means that the calculated free length of the spring is shortened. The main reason is that the initial compression treatment was not carried out, that is, the manufactured spring was compressed to its compression height or tightening height (if necessary) with great force, and could not return to its original state after loosening. Free length operation for. The amount of shortening is called "initial compression". After compression for 3-6 times, the length is no longer shortened, i.e. the spring is "positioned". The spring undergoes permanent deformation after initial compression.
