62 SELF-THREADING FEMALE FASTENER ELEMENTS AND METHOD OF FORMING SAME EP03787090 2003-11-24 EP1576296A4 2006-09-27 LADOUCEUR HAROLD A
A female fastener having a self-threading bore for threaded receipt of a conventional male threaded fastener which forms a substantially continuous female thread without tapping having a prevailing torque. The bore includes a cylindrical internal surface and a plurality of circumferentially spaced concave recesses having a total volume equal to an annulus defined by a major diameter and an inner diameter of the cylindrical surface. A method of forming self­attaching fasteners by rolling a continuous metal strip having a central pilot, piercing spaced self-threading bores through the pilot and either severing the pilot or the strip. Where the strip is severed into discreet fasteners, the fasteners may be interconnected by a frangible connector without reorienting the fasteners.

The method of forming self-attaching female fasteners (26) by rolling a continuous metal strip (20) including a central pilot portion (28) having parallel sides and flange portions (32) on opposed sides, severing at least the pilot portion (28) and cold forming the rectangular pilot portion (28) into a cylindrical end portion (38). Wing-shaped radial portions (40) are formed in the pilot portion (28) which may be severed or remain for anti-rotation features. The strip may remain continuous, wherein the severed pilot portions (28) are spread and the flange portions (32) are thinned or the strip may be severed into discreet fasteners. The female fasteners thus include generally cylindrical pilot portions (28) and rectangular flange portions (32) which may include rolled grooves.

A method of forming a female fastener including rolling a body portion strip having a midportion and flange portions on opposed sides of the midportion, piercing spaced openings through the midportion, cutting the strip to length between the openings, cold forming a separate generally cylindrical pilot portion having a length greater than the width of the midportion and a diameter greater than the opening through the midportion, preferably including radial splines, and press fitting the pilot portion through the opening in the midportion. The self-attaching female fastener thus includes a rectangular body portion and a generally cylindrical pilot portion having an end face spaced above a plane of the midportion and may be formed of a harder metal than the body portion.

The present invention is an assembly and method for continuously manufacturing fasteners. A die press (20) actuated at a first speed receives the contoured wire (16) into a die having a piercing element for piercing an aperture and a cutting element for cutting a fastener from the wire. A guide (36) receives the fasteners from the die press and a drive unit (42) engages the fasteners oriented by the guide (36) and conveys the fastener to an elevated height relative to a tapping device (38). The guide redirects the fasteners by a first router (46). The fasteners are gravity fed into the first router (46) and redirected to one of the tapping devices (38). Each tapping device (38) has a tapping element for forming internal ribs in the aperture of the fastener. The tapping devices (38) each actuates at a second speed that in aggregate is generally equal to the first speed of the die press (20).

An assembly line (10) for continuously manufacturing fasteners (12) from a rod (14) with a groove (18) for receiving a wire for retaining the fasteners (12) in a strip includes a receiver for receiving the rod (14). A die press (22) is arranged to receive the rod (14) from the receiver and includes a piercing member (170) for piercing an aperture (38) in each fastener (12) and a cutting member (180) for cutting each fastener (12) from the rod (14). A tapping member (32) provides ribs (36) to an inner wall of the aperture (38) formed in the fastener (12) by the piercing member (170). An inspector (42) inspects the internal rib (36) formed into the inner wall of the aperture (38) disposed in the fastener (12) verifying exactness of the aperture (38) and the rib (36). A wire inserted (94) inserts the wire into the groove (18) forming a strip of connected fasteners (12). The inserted (94) receives the fasteners (12) sequentially from the inspector (42) after verification of the exactness of the aperture (38) disposed in each fastener (12).

The invention relates to a method for producing hollow bodies such as nut elements to be fastened to components that usually consist of sheet metal. The invention especially relates to a method for producing hollow bodies with an at least substantially square or rectangular outline by cutting individual bodies from a profile in the form of a profile rod or a reel after respective holes have been punched into the profile, and optionally afterwards producing a threaded cylinder. The inventive method is further characterized in that before or after the punching of the profile a passage treatment is carried out in order to produce a cylindrical or annular projection, concentric to the punching or the intended punching, on the side of the profile facing the component by flow of material. The projection is optionally shaped to an annular punched section in an additional molding cycle. The invention further relates to various hollow bodies, assembly units and molds for producing said hollow bodies.
