Patent number: 10010929Abstract: An apparatus to produce a self-piercing and clinch nut includes a first forging die assembly, a second forging die assembly, a third forging die assembly, a transfer mechanism, and a controller. The first forging die assembly subjects a blank to first processing. The second forging die assembly is adjacent to the first forging die assembly, and subjects the blank, which has undergone the first processing in the first forging die assembly, to second processing. The third forging die assembly is adjacent to the second forging die assembly, and subjects the blank, which has undergone the second processing in the second forging die assembly, to third processing. The transfer mechanism transfers the blank between two adjacent forging die assemblies among the first to third forging die assemblies. The controller controls operations of the first to third forging die assemblies and the transfer mechanism.Type: GrantFiled: January 15, 2016Date of Patent: July 3, 2018Assignee: SHINJO HOLDINGS CO., LTD.Inventor: Tadashi Shinjo

Patent number: 7651401Abstract: The method of forming self-attaching female fasteners by rolling a continuous metal strip including a central pilot portion having parallel sides and flange portions on opposed sides, severing at least the pilot portion and cold forming the rectangular pilot portion into a cylindrical end portion. Wing-shaped radial portions are formed in the pilot portion which may be severed or remain for anti-rotation features. The strip may remain continuous, wherein the severed pilot portions are spread and the flange portions are thinned or the strip may be severed into discrete fasteners. The female fasteners thus include generally cylindrical pilot portions and rectangular flange portions which may include rolled grooves.Type: GrantFiled: November 24, 2003Date of Patent: January 26, 2010Assignee: Whitesell International CorporationInventors: Harold A.

Patent number: 5624319Abstract: A process for production of a two-part cage nut from a single metal plate. The cage nut includes a nut slidably carried on a holding part. The nut includes a base plate having a threaded sleeve. The holding part includes a holding plate having an aperture and a pair of side walls which are bent over the edge of the base plate of the nut. The process production includes stamping the holding part and nut from a single metal plate. The nut is joined to the base plate by a narrow connecting web. The base plate is then bent about the connecting web and positioned over the holding plate between the side walls. The side walls are bent inwardly until they extend over the side edges of the base plate of the nut. The nut is separated from the holding plate by shearing off the now bent over portion of the connecting web. The nut is permitted to slide between boundary tabs on a guide path between the side walls.Type: GrantFiled: September 15, 1995Date of Patent: April 29, 1997Assignee: A. Raymond GmbH & Co.
