锡青铜是一种良好的弹性材料,常用作弹性零件。正由于它弹性好,而且存在各向异性,给压弯模具的设计和制造带来困难。由于压弯后回弹很大,零件往往达不到图纸要求。而且锡青铜属于固溶体金属,加热无相变,不象其他弹性金属材料一样能通过退火→压弯→淬火恢复弹性的工艺过程进行加工。一般只能在模具设计中考虑,用改变弯曲角度来解决,但这种计算往往不易准确,
Tin bronze is a good elastic material, often used as elastic parts. Due to its good elasticity and anisotropy, it is difficult to design and manufacture the bending die. Due to the great rebound after bending, parts often can not meet the requirements of drawings. And tin bronze is a solid solution metal, heating without phase change, unlike other flexible metal materials can be annealed → bending → quenching recovery elastic process for processing. Generally only considered in the mold design, to change the bending angle to solve, but this calculation is often not easy to accurately,
