Spring steel wire maintenance
2019/7/26 view:
Spring steel wire in various industries more widely, I do not know everyone on the spring wire maintenance know how much? The next Xiaobian to introduce you to the next:
1 to avoid raising the temperature to shorten the time for a spring tempered manner;
(2) Hardness: with tempering temperature, the hardness increased slightly after the fall. The best temperature is slightly lower than the fatigue properties of hardness maximum temperature;
3 necking: tempered steel spring diameter will be reduced, so the coil spring should be set aside some size;
4 spring-tempered color: color temperature and tempering steel surface residues on, uneven color and temperature distribution inside the furnace or air flow related
If the desired color uniformity, and loading the stove to manage the way; if there is oil or partial fingerprints, after tempering will change;
5 spring: After hammering mild tempering can reduce deformation;
6 tension spring: there will be initial stress after tempering losses set deviation should be considered to allow loss;
