Publication number: 20100083483Abstract: Double-action clinching includes establishing a first layer on a second layer, and securing the layers between a tool's punch and clinching punch. First layer has less ductility than second layer, and clinching punch diameter is smaller than punch diameter. Layers are secured so: a tool support receives a portion of a second layer surface; clinching punch, slidably positioned in the support, is adjacent another portion of the second layer surface; and punch, positioned opposed to clinching punch, is adjacent a portion of a first layer surface. Pressing the punch into the first layer surface portion forms an aperture through the first layer. Pressing the clinching punch, in a direction opposite to the punch pressing, into the other portion of the second layer surface forces portion(s) of the second layer into the aperture, and forms a micro-interlocking flush-back joint between an aperture side wall and the second layer portion(s).Type: ApplicationFiled: October 8, 2008Publication date: April 8, 2010Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventor: Jon T.

Patent number: 6925698Abstract: A self-attaching fastener installation head and feed mechanism including a spring-biased L-shaped feed pawl which feeds a first nut in the feed passage adjacent the plunger passage on the upstroke of the die press. The feed pawl is pivotally supported on a slide bracket which includes a roller in the longitudinal axis of the feed passage which is biased against a central cam surface on the base and the base is interconnected to the nose member by removable pins. A spring biased nut restrictor is pivotally supported on the nose member, simplifying removal of a nut strip from the head and the installation head is more rugged in design and has fewer parts, reducing costs.Type: GrantFiled: August 8, 2003Date of Patent: August 9, 2005Assignee: FabriSteel Products, Inc.Inventors: Dale H.

Patent number: 6915553Abstract: Seaming apparatus and method for seaming ends to cans are described. The seaming apparatus includes a seaming chuck received by the can end. The chuck includes an anvil portion and a peripheral upper anvil wall. The upper anvil wall is inclined at an angle ? of greater than or equal to 6 degrees. The seaming apparatus also includes a seaming roll having a seaming surface for engaging the peripheral curl of the can end in a seaming operation to compress the peripheral curl against the peripheral flange and the peripheral upper anvil wall of the seaming chuck. The seaming surface of the seaming roll is inclined relative to the longitudinal axis by an angle ?. The value of ? is selected to be greater than about 4 degrees, and more preferably from between about 8 and about 14 degrees. Additionally, the value of ? bears a close approximate relationship to the value of ?, and in particular the value of angle ?=?±up to about 4 degrees.Type: GrantFiled: February 19, 2003Date of Patent: July 12, 2005Assignee: Rexam Beverage Can CompanyInventors: Timothy L.

Patent number: 6851165Abstract: An apparatus and method for retaining a poppet seal with respect to a housing of an integrated pressure management system. The integrated pressure management system includes an aperture near a mouth of a housing, and the mouth includes a tip that is deformable so as to retain the poppet seal in the aperture. The apparatus includes a die and a collet. The die moves along an axis, and includes a face adapted to engage the mouth. The face includes a forming-over section adapted to engage the tip. The collet surrounds the die and extends along the axis between first and second axial ends. The collet includes first and second portions. The first portion extends between the first axial end and an intermediate axial position. The second portion extends between the intermediate axial position and the second axial end, and includes a plurality of segments positioned about the axis.Type: GrantFiled: September 24, 2002Date of Patent: February 8, 2005Assignee: Siemens VDO Automotive, Inc.Inventors: Allen Tamman, David Rene Forgeron

Patent number: 6851167Abstract: A spin-pull blind insert tool utilizes a control system that generates a stop signal based on the relationship between the force values and the motion values derived from the action of the tool mandrel. The improved control system utilizes the shape of the force-deformation curve and not just a given pre-set force value or pull distance. Hence, the control system of the present invention does not require any set-up for changes in panel thickness unless the mandrel is also changed to install a different thread size. This control system develops a force-deformation curve as the fastener is being installed. The stop signal is generated when a pre-set deformation point has been exceeded and the shape of the force curve can be characterized by either of two types. For either type, an algorithm is followed which establishes an optimum stopping point for the installation tool regardless of the panel thickness into which the blind rivet is being installed.Type: GrantFiled: April 9, 2004Date of Patent: February 8, 2005Assignee: PEM Management, Inc.Inventors: Gary Harlow, Ronald S.

Patent number: 6842962Abstract: A method and apparatus for joining together two or more superimposed generally planar sheets by setting a fastener in engagement with the sheets at a predetermined location. The sheets are superimposed and placed in a fastener setting and sheet deforming assembly. The assembly is then operated to set a fastener into the sheet and to deform the sheets out of their planes around the predetermined locations. The sheets may be deformed before the fastener is set, after the fastener is set, or simultaneously with setting of the fastener. Sheet deformation may be achieved using appropriate clamping arrangements or by providing recesses into which the sheets are deformed during the course of rivet insertion. The invention also relates to a rivet for use in the method.Type: GrantFiled: September 23, 1998Date of Patent: January 18, 2005Assignee: Henrob LimitedInventor: Stuart Edmund Blacket

Patent number: 6817079Abstract: The method of the present invention is intended to be used in association with a headed fastener such as a tee nut, but not limited to a tee nut. The present method contemplates embodiments of a riveting pin having protuberances that cause the flared end of the shaft to be flared in one or more discontinuous portions of the circumference of the shaft, whereby “push out” and “spin-out” are deterred. Where the length of the fastener shaft is no longer than the thickness of the material through which it is inserted, a first design of flaring pin is provided. Where the length of the shaft of the fastener employed is greater than the thickness of the material through which it extends, a second embodiment of flaring pin is employed. In the former case, at least one discrete portion of the circumference of the shaft is flared into the wall of the passageway through which the shaft extends.Type: GrantFiled: November 20, 2002Date of Patent: November 16, 2004Assignee: Falcon Fasteners Reg'DInventors: Walter H.
