摘要
阐述了自冲铆接技术的概念、类型、工艺原理以及自冲铆接技术在汽车车身制造中的应用。对自冲铆接技术与电阻点焊技术连接质量的比较表明,凡是难于进行焊接的连接件均可采用自冲铆接技术,且自冲铆接件的疲劳强度高于焊接件。介绍了半空心铆钉的自冲铆接工艺在车身制造中的应用情况及其铆接质量的评价方法。
Definition,types and process principle of the self-pressing riveting technology and its application in auto body manufacture are introduced.It is shown by comparison between self-pressing riveting joint and resistance spot weld-ing that all the components which are difficult to be jointed with resistance spot welding can be jointed with self-pressing riv eting technology,and its fatigue strength is better than welding.Application of self-pressing rivet joint technique with se-mi-cavity riv ets in body manufacture and the quality evaluation methods for it are introduced.
