    • A fastener mandrel (20) has formed on one end a shoulder (42) and a twisted, generally rectangular shaped head (40) adjoining the shoulder. In setting the fastener in a workpiece, the shoulder enlarges the end of a tubular rivet (22) and clamps workpieces together in combination with a preformed head (26) on the other end of the rivet (22). The mandrel head (40) deforms the rivet tail (28) into a twisted appearing shape with a somewhat elliptical cross section that partially encloses the mandrel head (40) to provide good stem retention and prevent axial looseness. A plurality of axial ribs (48) on the mandrel stem (38) are drawn into a reduced diameter section of the rivet head end when the rivet is set, thereby providing additional stem retention and torsional interference.
    • 紧固件心轴(20)在一端形成有肩部(42)和与肩部相邻的扭曲的大致矩形的头部(40)。 在将紧固件设置在工件中时,肩部放大管状铆钉(22)的端部,并将工件与铆钉(22)的另一端上的预成形头(26)组合在一起。 心轴头(40)将铆钉尾部(28)变形成扭曲的形状,其形状稍微椭圆形,部分地包围心轴头(40),以提供良好的杆保持力并防止轴向松动。 当铆钉被固定时,心轴(38)上的多个轴向肋(48)被拉入铆钉头端部的直径减小的部分,从而提供额外的杆保持和扭转干涉。

    • Blind rivet stems and method of making the same resulting in reduced cost in the fabrication of the rivet and increased strength in the installed rivet. In accordance with the method, after the shear ring (20) is formed on the stem, the relief (26) adjacent the shear ring on the tail-former end (22) of the stem is formed by a rolling operation, with the cylindrical portion of the tail (34) of the stem being knurled in the same or in a separate rolling operation. If desired, a shoulder collar may also be formed at the tail end of the stem prior to or subsequent to the rolling operation or operations. The knurled stem tail provides better gripping by the installed rivet and increases the strength thereof by providing a relatively high and constant pull relatively independant of grip, and by tending to prevent the extrusion of the tubular sleeve (56) out of the hole in the parts being joined on the passage of the stem tail into the portion of the tubular sleeve within the hole, both due to the tendency of the knurled region to carry the sleeve material with it during drawing of the rivet, and for the further reason that the knurling provides a good grip on the shear ring (20) and the end of the sleeve, yet has sufficient open spaces within which the sleeve material may extrude if required.
    • 盲铆钉和其制造方法导致铆钉的制造成本降低并且在所安装的铆钉中增加强度。 根据该方法,在杆上形成剪切环(20)之后,通过滚动操作形成与杆的尾部成形器端部(22)上的剪切环相邻的浮雕(26),其中圆柱形 杆的尾部(34)的部分以相同的或单独的滚动操作滚花。 如果需要,也可以在滚动操作或操作之前或之后在杆的尾端处形成肩环。 滚花的杆尾通过安装的铆钉提供更好的夹持,并且通过提供相对独立于抓握的相对高且恒定的拉力来提高其强度,并且通过倾向于防止管状套筒(56)挤出部件中的孔 由于在拉拔铆钉期间滚花区域随着其携带套筒材料的倾向,所以在杆尾部进入孔内的管状套筒的部分中的连接处,并且为了进一步的原因,滚花 提供了对剪切环(20)和套筒端部的良好抓地力,但具有足够的开放空间,如果需要,套筒材料可在其内挤出。
