Abstract:
A method for assembling materials using a riveting device of the kind which comprises a plug (2) and a sleeve (1). The sleeve (1) is provided on its outer surface with a peripheral recess, in particular a groove (5), in order to form a folding zone, while the plug (2) has a head (9) which can deform the tubular end of the sleeve and fold it back in the folding zone. During riveting, the sleeve's peripheral recess protects the start point of the countersink of the materials from stress and folding said sleeve results in a large bearing surface in perfect contact with the materials.
Abstract:
A blind rivet including a mandrel having a head and a rivet body surrounding the mandrel adjacent the head, the mandrel including at least one locking region for locking engagement therewith of the rivet body, adjacent the head, a selectably breakable region adjacent the at least one locking region and defining a plurality of breakable locations along the mandrel and a gripping region adjacent the selectably breakable region.
Abstract:
The invention relates to a blind structural rivet for permanently joining predrilled components which are in the correct mutual alignment and are accessible from one side only. It consists of four components: a "mandrel" rod (1); a milling head or flat round head bush (2); a deformation bush (3); and a locking ring (4). This fixing is carried out with a gun-type rapid applicator device. It can be applied by an automatic system by long-distance computer control which also monitors it. The fixing is given an indented marking to identify the manufacturer and also briefly identify the materials.
Abstract:
Die Erfindung betrifft ein Verfahren zum Fügen wenigstens zweier Bauteile (9, 10), insbesondere zweier Blechbauteile einer Fahrzeugkarosserie, mittels einer einen Mantelbereich (2), einen ersten Randbereich (3) und einen zweiten Randbereich (4) umfassenden Fließformniethülse (1), in welche ein einen Grundkörper (6) und einen Kopf (7) umfassender Zugschaft (5) eingeführt wird und welche in jeweilige, zumindest im Wesentlichen miteinander fluchtende Durchgangsöffnungen (11, 12) der Bauteile (9, 10) eingeschoben wird, wonach durch eine Relativbewegung (13) des Zugschafts (5) zu der Fließformniethülse (1) diese im ersten Randbereich (3) aufgeweitet und mit einem Bauteil (9) in Anlage gebracht wird, wobei der zweite Randbereich (4) mittels eines den Zugschaft (5) umgebenden Umformwerkzeugs (14) zum anderen Bauteil (10) hin umgebogen und mit dem anderen Bauteil (10) in Anlage gebracht wird, sowie ein Fügeelement zum Fügen wenigstens zweier Bauteile (9, 10).
Abstract:
A fastener installation tool (10) includes a nose assembly (30), first (18) and second (20) cylinders, first (14) and second (16) pistons, and a yoke (22). The nose assembly (30) is adapted to apply an axial load to a fastener along a longitudinal axis of the nose assembly (30). The first (18) and second (20) cylinders are diametrically opposed to one another with respect to the longitudinal axis of the nose assembly (30). The yoke (22) connects the first piston (14), the second piston (16), and the nose assembly (30) such that motion of one of the pistons (14, 16) causes motion of the other one of the pistons (14, 16) and motion of at least a portion (32) of the nose assembly (30).
Abstract:
A fastening system includes a fastener (10) having a bolt (12) with a pull portion (28) having at least one pull groove (28a), and an outer sleeve (14) having a head (42) with an inner face (46), the bolt (12) being inserted within the sleeve (14). The fastening system includes a fastener installation tool (60) having a puller (62) with at least one tooth (68) and a front face (72). The inner face (46) of the head (42) of the sleeve (14) is angled at an angle measured transverse to a longitudinal axis (X-X) of the fastener (10), while the front face (72) of the puller (62) of the fastener installation tool (60) is angled at an angle measured transverse to a longitudinal axis (Y-Y) of the puller (62). The angles are chosen to match or be substantially the same. The front face (72) of the puller (62) of the fastener installation tool (60) is adapted to engage the inner face (46) of the outer sleeve (14) of the fastener (10) when the fastener installation tool (60) engages the fastener (10), and the inner face (46) of the outer sleeve (14) facilitates the receipt of the front face (72) of the puller (62) and the alignment of the at least one tooth (68) of the puller (62) with the at least one pull groove (70) of the bolt (12) by allowing the puller (62) to shift forward or backward to facilitate such alignment.
Abstract:
An adaptor coupling (13) for providing a rotatable connection between an installation tool (12) and an offset nose assembly (10) for setting pin and collar type fasteners enables previously non-rotatable nose assemblies (10) to be rotated around the end of the installation tool (12) to enable the nose assembly (10) to access and set difficult to reach fasteners while at the same time minimizing operator fatigue.
Abstract:
A tool for installing a blind fastener including a core bolt and a core nut is provided. The tool includes a driving member, a collet driven by the driving member for engaging the core bolt, and an external sleeve for holding the core nut and preventing the core nut from rotating during installation of the blind fastener. The external sleeve is movable between a first position in which the external sleeve is driven by the collet to rotate with the collet and a second position in which the external sleeve is stationary despite rotating action of the collet.
