轿车主要零部件冲铆设备的设计
DESIGN OF MAIN PARTS RIVETING EQUIPMENT FOR PASSENGER CAR
摘要
通过降低汽车车身的质量，可以使汽车的许多性能得到显着地改善和提高，所以车身的轻量化生产是汽车制造工业要研究与发展的。汽车的轻量化主要的办法是在车身制造中使用大量的铝等轻型的金属，目前，传统的焊接方法对铝等金属的链接时没有什么作用的。实验表明，使用自冲铆技术在连接铝合金等有色金属时，它的抗静拉力和抗疲劳性要优于电焊工艺。因此，自冲铆接机在制造车身方面具有良好的应用前景。自冲铆钉机在铆接中无需先前钻孔，能够实现一次冲铆完成，适用于汽车车身生产。
自冲铆接是一种比较新的工艺，主要是连接金属板料，作为连接板料和铆钉的这种工艺，不用事先去打孔，主要是用半空心、实心的铆钉当作冲孔的工具来实现这种机械连接工艺。
本设计要求冲铆设备能够实现对零件的冲铆工作，冲压位置准确，冲压力可检测，设备的工作位置可调整，采用液压驱动的方式，工作过程有安全保护等。冲铆机布局的方式选用悬挂式，铆接机框架的形式选用E型框架。

By reducing the quality of the car body, can make many of the performance of the car has been significantly improved and improved, so the body of the lightweight manufacturing is the automobile manufacturing industry to research and development. The main measure of theweight of the car body is the use of aluminum and other non-ferrous metals in the body manufacturing, the traditionalwelding process for this type of metal connection is powerless. Experiments show that the use of self-riveting technology in the connection of aluminum and other non-ferrous metals, its anti-static and anti-fatigue is better than thewelding process. Therefore, since the riveting machine in the manufacture of body has a good application prospects. Self-piercing riveting machine in the rivetingwithout the need for previous drilling, to achieve a riveting complete, suitable for automobile body production.
Self-piercing riveting is a relatively new process for the connection of sheet metal, forming a connection between the sheet and the rivet,without pre-punching, but using the semi-hollow, solid rivet as punching tool A high-speed mechanical connection process.
?The design requirements of the riveting equipment to achieve the impact of the parts of the rammingwork, accurate stamping position, punching force can be detected, the equipment can adjust theworking position, the use of hydraulic drive, thework process has security protection. Riveting machine layout of theway to use hanging, riveting machine frame in the form of E-type frame.
Keywords: Self-riveting equipment; Hydraulic; suspension; E-type frame
