    • A self-piercing rivet of a special rivet geometry is described, which in particular is suitable for joining high strength steel sheets, but can also be used for other metal sheets. The self-piercing rivet is in particular characterized by a special underhead geometry as well as a special geometry of the rivet foot (cutting region). Thus the self-piercing rivet has an underhead chamfer which with a radial plane of the self-piercing rivet encloses an angle of 20°+5°/−5° and merges tangentially into the cylindrical outer surface of the rivet shank via a radius. In the region of the rivet foot the self-piercing rivet has a plane shank face, which extends essentially at a right angle to the rivet axis and which merges “smoothly” into the cylindrical inner surface via a shank inner surface and a radius. In comparison to conventional self-piercing rivets the special rivet geometry enables lower joining forces and tensile forces in the joining operation, an optimized load bearing performance and an optimum joint quality of the self-piercing rivet joint as well as minimum gap formation between the rivet and the metal sheet.
    • 描述了特殊铆钉几何形状的自穿孔铆钉,其特别适用于连接高强度钢板,但也可用于其它金属板。 自穿铆钉的特征特征在于特殊的底部几何以及铆钉(切割区域)的特殊几何形状。 因此,自穿铆钉具有底部倒角,其中自穿孔铆钉的径向平面包围20°±5°/ -5°的角度,并通过半径切向地并入铆钉柄的圆柱形外表面。 在铆钉脚的区域中,自穿铆钉具有平面柄面,其基本上以与铆钉轴线成直角的方式延伸,并通过柄内表面和半径“平稳地”并入圆柱形内表面。 与传统的自穿铆钉相比,特殊的铆钉几何能够在接合操作中实现较低的接合力和拉力,优化的承载性能以及自穿铆钉接头的最佳接头质量以及铆钉之间的最小间隙形成 和金属片。
