从铍青铜的力学性能和零件的结构要求入手,分析了弯曲件的成形工艺特点。由于零件厚度薄、多向弯曲、回弹量大且相互影响,用常规回弹补偿法很难确定回弹规律。实际分析发现,用有限元模拟法很难得到合适的修模尺寸,而对铍青铜零件在冷成形前进行固溶处理,成形后进行时效处理,具有成形时塑性好,成形后弹性极限高等特点。本文介绍了热处理方法,设计了相应的模具结构。结果表明,该方法能有效解决零件成形后回弹难以控制的问题并且可以应用于类似零件的弯曲成形。

According to the mechanics property of the beryllium bronze and the structure of the part,the forming characteristics of the bending part is analyzed.Since the part is thin,multi-direction bending and springback is large,it is very difficult to decide the springback law using the usual compensation method.It is not easy to get a reasonable die correction size,however,the way that the beryllium bronze part carried through solution treatment before bending and aging treatment after bending is an effective solution to solve the problem of springback after stamping.In this paper,we adopt the heat treatment method to design the die structure.The result shows that it is an effective way to control the springback using the heat treatment method.
