Abstract: The method disclosed herein is suitable for forming a fastener having a panel receiving re-entrant groove, such as a piercing nut or fastener having a central pilot portion and a surrounding groove which is restricted at the open end. The method includes impacting the pilot or piercing face of nut blank with a punch having an annular protrusion forming the central pilot portion and a surrounding groove having parallel side walls. The grooved end of the fastener is then forced into a tapered die opening, deforming the outer side wall of the groove inwardly to provide a restricted or re-entrant groove opening. In the disclosed method, the nut blank is first deformed in a hexgonal die and the outer groove wall is also hexagonal. The nut blank is then pierced, through the pilot portion.

Abstract translation: 本文公开的方法适用于形成紧固件，该紧固件具有接收重入凹槽的面板，例如具有中心导向部分的穿孔螺母或紧固件，以及限制在开口端的周围凹槽。 该方法包括用具有形成中心导向部分的环形突起的冲头和具有平行侧壁的周围凹槽冲击螺母毛坯的导向面或刺穿面。 然后紧固件的开槽端被迫进入锥形模头开口，使凹槽的外侧壁向内变形，以提供限制或重新开口的凹槽开口。 在所公开的方法中，螺母坯料首先在正交模具中变形，并且外槽壁也是六边形。 然后通过导向部分刺穿螺母毛坯。

Abstract: A method of making a laminated nut or nut clip having a threaded bore. The lamina may be formed by spirally rolling the end of a strip, flattening the spiral roll, piercing the lamina and forming the threaded bore. The threaded bore is formed by piercing the lamina through one face and then extruding an integral barrel through the pierced hole from the opposite face of the lamina. The barrel is then defined by a plurality of nested cone-shaped portions formed in the lamina in the extrusion step.

Abstract: A nut formed of a plurality of laminae relatively fixed at their opposite ends, in face to face relation, having an integral barrel portion surrounding a threaded bore. The barrel portion is defined by nested cone-shaped portions formed in the laminae and the threads of the bore are formed in the edges surrounding the bore. In the preferred embodiment, the laminae are formed from a spirally folded strip and a U-shaped clip portion is formed in the end of the strip.

Abstract: A method of securing a nut to a panel, including deforming the panel into a groove or recess in the nut by advancing a punch against the panel face opposed to the nut, deforming the panel edge beneath and against an inclined outer wall of the nut groove and further advancing the punch into a tool receiving recess in the bottom of the groove, beyond the panel edge. In one disclosed embodiment, the nut pierces its own hole in the panel. In the other embodiment, the panel is pre-pierced and the nut is clinched to the panel.
