Abstract: A method for producing captive washer wheel nuts. The washer and nut body are formed as a single piece, greatly simplifying and reducing the number of separate manufacturing steps, such as threading and forming bearing surfaces on the washer and nut body. An axially symmetric frusto-conical groove at an oblique angle to the axis of symmetry is formed in the nut-washer blank. The groove is sufficiently deep to be closer to the axis of symmetry than a small-radius concave feature on the underside of the washer. Upon application of axial compression, the washer separates from the nut body along a frusto-conical fracture surface defined between the bottom of the groove and the concave feature on the washer. The orientation of this fractured surface causes the washer to be captured to the nut body.
Abstract translation: 一种用于生产垫圈轮圈螺母的方法。 垫圈和螺母体形成为单件，大大简化和减少了单独的制造步骤的数量，例如在垫圈和螺母本体上穿过并形成轴承表面。 在螺母垫圈毛坯中形成一个与对称轴成斜角的轴向对称的截头圆锥形槽。 凹槽足够深以便比垫圈下侧的小半径凹形特征更靠近对称轴。 在施加轴向压缩时，垫圈沿着限定在槽的底部和垫圈上的凹形特征之间的截头圆锥形断裂面与螺母体分离。 这种断裂表面的方位导致洗衣机被捕获到螺母体上。

Abstract: An apparatus particularly useful for securing a deformable nut having a hole to carrier material, such as a sheet-metal panel, is disclosed. Securement of the nut to the panel is made employing essentially a one-step procedure to form a hole in the panel and to secure the nut to the panel at the panel hole. The securement procedure generates essentially no panel-material waste. Various elements of the apparatus cooperate to secure the nut to the panel. On the apparatus, a ram initially causes a nut guide to secure the panel to the apparatus, and eventually causes a piercing punch to be advanced along a path toward a receiving punch. The latter action causes the panel to be pierced. Further advancement of the ram toward a base of the apparatus causes portions of the panel adjacent the pierced portion to be urged or otherwise drawn into the nut hole, and eventually causes the nut to deform. The latter action causes the nut to be secured to the panel.
Abstract translation: 公开了一种特别可用于将具有孔的可变形螺母固定到载体材料（例如金属板）上的装置。 通过基本上一步一步的过程，将螺母固定到面板上，以在面板上形成孔并将螺母固定在面板孔处的面板上。 固定程序基本上不产生面板材料浪费。 该装置的各种元件协调以将螺母固定到面板上。 在该装置上，冲头最初使螺母导向件将面板固定到装置上，并且最终使穿孔冲头沿着朝向接收冲头的路径前进。 后一种动作导致面板被刺穿。 冲压器朝向设备的基部进一步前进使得邻近穿孔部分的面板的部分被推动或以其它方式被拉入螺母孔中，并且最终导致螺母变形。 后一种动作使螺母固定在面板上。

Abstract: A strip of fasteners such as pierce nuts is formed from a metal blank with no scrap resulting from the provision of a spacing between adjacent nut bodies, and without the difficulty and expense incident to attaching nut bodies to connecting elements. The body portion of a laterally flanged blank is severed in the transverse direction to separate nut bodies from the blank without fracturing the flanges. The flanges are severed in the longitudinal direction to form severed longitudinally extending flange segments integral at both ends with unsevered flange segments. When the flanges are straightened, the stretching of the severed flange segments resulting from shearing provides a spacing between adjacent nut bodies in the strip. The strip includes spaced apart nut bodies interconnected by continuous lateral flanges. The flanges include unsevered lateral flange segments integral with both sides of each nut body, and severed flange segments integral at both ends with the unsevered flange segments. Elongation of the severed flange segments provides spacing between adjacent nut bodies.
Abstract translation: 紧固件如刺穿螺母由金属坯料形成，不需要在相邻的螺母体之间设置间隔而产生的废料，并且没有将螺母体连接到连接元件上的困难和费用。 横向凸缘坯料的主体部分在横向上被切断，以将螺母体与坯料分离，而不会破裂凸缘。 凸缘在纵向上被切断，以形成在两端与一个未切割的凸缘段成一体的切断的纵向延伸的凸缘段。 当凸缘拉直时，由剪切产生的切割的凸缘段的拉伸在带中的相邻螺母体之间提供间隔。 该条带包括由连续的侧向凸缘互连的间隔开的螺母体。 凸缘包括与每个螺母体的两侧成一体的未切割的侧向凸缘段，以及在两端与未切割的凸缘段成一体的切断的凸缘段。 切割的法兰段的伸长提供相邻螺母体之间的间距。

Abstract: A method for manufacturing a self-locking spring nut is disclosed herein. In this method, a spring nut is tapped in its stretched or compressed condition, where a lead or pitch of the spring nut of a helical form is increased or decreased, say 0.5 to 6%. Accordingly, when a bolt is inserted into the spring nut thus prepared, then threads on the bolt undergo a compressive or tensile stress by the spring nut.As a result, the spring nut may be locked on a bolt in any position. This method utilizes an elasticity of the spring nut to be locked on the bolt, rather than interference between the female and the male threads on the nut and bolt, respectively, for instance, interference caused by deforming the configuration of threads or changing a pitch of a male thread relative to that of a female thread. Accordingly, the self-locking nut of the invention may be repeatedly used, without being damaged. The pitch of the spring nut of a helical form, however, should differ from the pitch of a tapped or female thread provided in the inner surface of the spring nut.

Abstract: A wheel nut having wrench flats extending parallel to a central threaded aperture is sheathed by a sheet metal cap which extends down the sides and covers one end of the nut. The end of the cap may extend straight across the end of the nut or may alternatively be domed to surround a volume extending beyond the end. The cap is welded to the nut at either a ring of points or a continuous ring extending around the nut end. Alternatively, the nut may have a radially extending skirt between its ends and the cap may be welded to the laterally extending sides of the skirt. These resistance welded joinders are formed by supporting the cap in loose assembly with the nut in an electrically conductive fixture, bringing a tubular electrode into pressured contact with the uncapped end of the nut and passing an extremely short pulse of high electric current through the contacting surface of the cap and nut end using a capacitive discharge welding circuit.

Abstract: A nut having a threaded bore including a cylindrical threaded portion through one end of the nut and a conical threaded portion opening through the opposed end of the nut for receiving the unthreaded portion of a bolt shank, without binding. The nut bore is formed by impacting one end of the nut blank with a cylindrical punch while the nut is supported on a die having an enlarged opening, breaking a cylindrical opening through the opposed end of the nut blank. The disclosed nut is a pierce nut and the conical bore portion opens through the pilot portion, eliminating the requirement for a countersink or counter-bore.
