铜引线冷弯成型工艺研究

Study on the Cold-bending Forming Process of Copper Lead

铜材的冷弯成型工艺广泛应用于发电设备制造中,工件传统的制作流程是R值根据经验设定、手工操作弯型,产品质量的稳定性较差。本文就铜材冷弯成型R值设计、材料物理性能要求、弯型工艺方法、回弹现象进行了分析和试验探讨,提出了一套可靠性较高的铜材冷弯成型制造工艺方案。

The cold-bending forming of copper lead is widely used in power generation equipment manufacturing.The traditional producing process is that the R value of the workpiece set according to experience and manual bending.The stability of product quality is usually poor.In this paper,the design of R-value of copper cold-bending forming,the requirements of physical properties of materials,the bending process and the rebound phenomenon are analyzed and tested.A set of high-reliability copper cold-bending forming process scheme is proposed.
