硅锰青 3-1及锡磷青铜6.5-0.15制的各种片状冷冲压弹性零件经常须要在冷冲压过程中进行中间退火,但要求退火后仍保持所须的强度而不失其弹性。为此,我们试验了退火温度对其机械性能的影响,以便得出一个既满足冷冲压工艺所需的塑性要求,又不使零件损失弹性的最佳退火温度规范。 Various sheets of cold stamping elastic parts made of Si-Mn-3-1 and Sn-Phosphor-6.5-0.15 are often subjected to intermediate annealing during cold-stamping, but the required strength after annealing is required without loss of elasticity. To this end, we tested the effect of annealing temperature on its mechanical properties in order to arrive at an optimal annealing temperature specification that meets the plastic requirements required for cold stamping processes without sacrificing component flexibility.
