Spring steel wire is 1.
Outer diameter of the
spring is 8.
1, the height is 12.
3 (
After the total pressure, not total pressure is 13)
, after many debugging found it could be a spring residual deformation occurred.
Spring factory after the analysis of what is going to cause may have four kind of situations: 1, spring material tensile strength did not meet the standard requirements, steel wire is usually said soft, can change a batch number to give it a try.
2, spring pressure and deformation of beyond the limit deformation of spring, spring cannot when the design pressure and, calculate the deformation of test 3, spring end face grinding end coil annealing.
4, spring tempering temperature is exorbitant, can check temperature detection device and display device.
