利用自穿孔铆钉附接镁板的方法
摘要：
一种经由自穿孔铆钉将铝板附接到镁板的方法。所述方法包括：将铝板和镁板定位在一起，镁板支撑在具有模腔的砧座上。在砧座区域镁板被局部加热，然后自穿孔钢铆钉被冲压通过钢板并且仅仅部分进入镁板内，从而移动镁板进入腔内。镁的加热提高延展性以便自穿孔铆钉被接受时在镁材料上没有过度应变。在钢铆钉和镁板之间的接口被隐藏在铝板和镁板之间，从而保护在铆钉的钢质材料和镁板之间的接口不会暴露于环境。
摘要（英）：

A method for attaching an aluminum panel to a magnesium panel via a self-piercing rivet. The method includes positioning the aluminum panel and the magnesium panel together with the magnesium panel supported on an anvil having a cavity therein. The magnesium panel is spot heated at the locale of the anvil, and then the self-piercing steel rivet is punched through the steel panel and only partway into the magnesium panel, to displace the magnesium panel into the cavity. The heating of the magnesium improves the ductility so that the self-piercing rivet is accepted without undue strain on the magnesium material. The interface between the steel rivet and the magnesium panel is concealed between the aluminum panel and the magnesium panel to thereby protect the interface between the steel material of the rivet and the magnesium panel from exposure to the environment.
