自冲铆接设备研制及轻量化材料自冲铆接工艺开发

摘要
如今汽车轻量化已经成为汽车工业发展的必然趋势,而大量使用
铝合金和高强度钢等先进轻量化材料是解决汽车轻量化的重要手段
之一。传统的连接工艺在连接这些先进轻量化材料时面临着巨大的困
难;研究表明,自冲铆接方法是一种能够有效连接上述材料的新型工
艺手段。
文章首先通过选取适当的自冲铆接动力系统,并基于该系统设计
设备型框架及采用有限元分析手段对该框架的刚度进行了校核,结
果表明该型框架符合使用要求;而后,根据自冲铆接工艺特点及试
验目的完成了铆接总体结构的设计与制造,为之后的试验研究打下了
坚实的基础。
其次,引入模钉体积比的概念并制定详细的试验方案分别研究了
模钉体积比对铝—铝和钢—铝自冲铆接接头成形性能及其准静态强
度的影响;试验表明,一定范围内模钉体积比的增加有利于提高铆接
接头成形质量。
最后,在现有设备基础上开发了包括位移传感器、压力传感器以
及力—位移曲线显示与数据提取在内的一整套自冲铆接监测系统,并
将其用于深入分析两种接头的成形规律;试验表明,铝—铝和钢—铝

DEVELOPING OF EQUIPMENT AND PROCESS OF
SELF-PIERCING RIVETING FOR LIGHTWEIGHT
MATERIALS

ABSTRACT
Today, the trend of lightweight in automotive industry has e
inevitable, and extensive use of aluminum alloy, high strength steel or the
other advanced lightweight materials is one of the important means that
can solve this problem well. Traditional connective processes face with
enormous difficulties in connecting those materials, but research has
shown that self-piercing riveting method is a new process that can join
those materials effectively.
Firstly, selected the appropriate power system of self-piercing
riveting, and based on that power system a C-frame was designed and
checked for its stiffness by means of FEA, the result showed that this
C-frame was in line with the requirements, then according to the
characteristics of the self-piercing riveting process and the purpose of the
experiment, the whole riveting structure had been designed and
manufactured which laid a solid foundation for the next experiments.
Secondly, induced the concept of die-rivet volume ratio and made
