铆接
<DIV> 铆接</DIV><DIV> 铆接有冷铆和热铆两种方式。前者为形状锁紧连接，一般直径大于10mm的钢铆钉加热到1000~1100℃进行热铆，钉杆上的单位捶击力为650~800MPa。后者为力锁紧连接，直径小于10mm的铆钉可在常温下冷铆，用于不太重要的或受载不大的连接。</DIV>
<DIV> 铆接的基本要求为：</DIV>
<DIV> 1）铆接的材料与规格尺寸必须符合设计要求。铆钉孔的加工应符合有关标准规定。</DIV>
<DIV> 2）铆接时不得损坏被铆接零件的表面，也不得使被铆接的零件变形。</DIV>
<DIV> 3）除有特殊要求外，一般铆接后不得出现松动现象，铆钉的头部必须与被铆接零件紧密接触，并应光滑圆整。</DIV>
