The steel wire is 1.5 spring diameter is 8.1, the height is 12.3(motor rated power, not total pressure is 13), after several adjustments found that this may be the residual deformation of the spring. The reason is likely to have four conditions: 1 spring raw material compressive strength did not do the specification, is usually said that the steel wire soft, can be replaced by a batch of number to try.

2 The compression and deformation of the spring exceeds the ultimate deformation of the spring, that is, the spring design scheme can not be compressed, you can calculate the experimental deformation

The cutting of the inner hole of the spring leads to the hardening of the end ring.

4. If the temperature of spring tempering is too high, check the temperature measuring equipment and display instrument. Special-shaped spring manufacturers also have a spring field of heavy potential sales market is railway system software, with the deepening of the reform of railway system software, the sales market is gradually expanding the opening and the implementation of the overall planning of the railway, the car shock absorber system software encountered upgrading, traffic lines to install new shock absorber noise reduction components.
