摘要： The fastener installation head and bolster assembly of this invention is particularly adapted to assure constant installation pressure for fasteners installed in a reciprocating press die, such as pierce and clinch nuts. The fastener installation head includes a plunger supported on one die platen, a movable housing member which receives the fasteners to be installed, reciprocably supported on the plunger, and a die member supported on the opposed die platen, opposite the movable housing plunger passage. The bolster assembly includes a fluid pressure ram operably supporting the plunger between the plunger and the die platen having a source of constant fluid pressure and a plunger release which permits the plunger to recede when the press tonage exceeds the preferred fastener installation force.

摘要： The disclosed method and apparatus is adapted to form a low pressure fluid sealed nut and panel assembly for a flush mounted self-piercing bearing nut having a rectangular piercing pilot, panel bearing flanges on opposed sides of the nut and grooves in the flanges, adjacent the pilot, retaining the pierced panel edges. The improved method includes simultaneously shearing and deforming the nonflanged top edges and corners of the nut pilot beneath the panel to form a panel bearing surface on all four sides of the pilot and deforming the pierced panel edges into the grooves and against the grooved bottom walls and inner pilot walls, spaced from the bottom walls of the grooves, to form a sealed nut and panel assembly. The apparatus includes a clinch die having an opening configured to deform the pilot, as described, and clinching lips forming the panel in the nut grooves in sealed relation.

摘要： The present invention relates to an improved die member, panel and fastener assembly and method for installing a fastener into a panel. The die member has a pair of opposed clinching lips protruding from an end face. The opposed clinching lips have a contact face that narrows as it approaches the opposed ends of the contact face and sidewalls that are angled with respect to vertical. The lips, due to the dual angles, substantially and simultaneously drive panel metal into fastener grooves both longitudinally and laterally. The fastener and panel assembly have panel metal deformed into the fastener grooves resulting in generally wedge-shaped portions of panel metal in the opposed ends of the fastener grooves.
