A clinch-type fastener is formed by simultaneously creating an undercut during the same forging that creates the head and displacer of the fastener. A fastener blank is compressed end- to-end between top and bottom dies whereby the axial compression of a blank causes the outward bulging of the shank at its midline. Simultaneously, a tapered end point and a tangential interference band are formed provided by a curvilinear-shaped bulge in the shank. As the bulge is formed an undercut is created between the bulge and a shoulder which extends downwardly from a head of the fastener. This method of formation and the fastener produced thereby are particularly suited to the manufacture of small clinch pins having a diameter in the range of 1.0 mm.

A method for preparing ultra-fine grain titanium or titanium-alloy articles (78) used for adjoining or assembling of detail components is disclosed. Coarse-grained titanium or titanium-alloy materials (52) typically are heated and forced under constant pressure through a friction stir processing tooling device (50) containing a stirring chamber (54) and a stirring rod (58). As the material is passed through the stirring chamber (54), the stirring rod (58) solutionizes the titanium or titanium-alloy material (52) and stirs the material to obtain a homogeneous or uniform material condition. As the processed material exits the stirring chamber (54) of the friction stir process tooling device (50), it reconsolidates as an extremely homogeneous structure possessing ultra-fine grain structure. Titanium or titanium-alloy materials (52) having been processed to achieve such ultra-fine grain material structure may then be manufactured into aerospace structural articles or components such as fasteners (78) that do not require a subsequent heat-treatment steps (Fig. 2).

145 Machine for cropping and press-forming material fed in wire form EP99103978.5 1999-03-10 EP1036609A1 2000-09-20 Castiglioni, Albino

A machine (1) for cropping and press-forming material fed in wire form, which comprises a supporting structure (2) which slidingly supports a first assembly (3) which comprises a support (4) for at least one cropping and pressing punch. The supporting structure (2) further slidingly supports a second assembly (5) whose mass is suitable to counterbalance the mass of the first assembly (3). The machine (1) further comprises means for the synchronized actuation of the first assembly (3) and of the second assembly (5) with respect to the supporting structure (2) with a reciprocating motion along a sliding path in mutually opposite directions. The first assembly (3) and the second assembly (5) are arranged one above the other and the sliding path of the second assembly (5) is parallel and vertically spaced with respect to the sliding path of the first assembly (3).

146 PREPARATION OF PRE-COATED ALUMINUM ALLOY ARTICLES EP96915379 1996-05-01 EP0828863A4 2000-02-09 KEENER STEVEN G
An aluminum-alloy article such as a fastener or rivet (40) is prepared by providing an aluminum-alloy article precursor that is not in its final heat-treated state, and in one form is in its solution treated/annealed state. A curable organic coating material is also provided. The method includes anodizing the article precursor, preferably in chromic acid solution and without chemical sealing during anodizing, applying the organic coating material to the aluminum-alloy article precursor, and precipitation heat-treating the coated aluminum article precursor to its final heat-treated state, thereby simultaneously curing the organic coating. If the aluminum alloy temper is of the naturally aging type, it is optionally lightly deformed prior to precipitation treatment aging. The approach may also be applied to articles that are not solution treated/annealed and aged, by first overly deforming the article precursor so that the curing treatment of the coating also partially anneals the article precursor to the final desired deformation state.
147 Stanzniet sowie Verfahren zu dessen Herstellung EP98118855.0 1998-10-06 EP0908636A1 1999-04-14 Hahn, Ortwin, Prof. Dr. Ing.; Kurzok, J. Dipl.-Ing.

Die Anmeldung betrifft einen Stanzniet mit einem Setzkopf, einem Schaft und einem Schaftfuß sowie ein Verfahren zu deren Herstellung.

Ein Nachteil, der eine weitere Verbreitung von Stanznieten behindert, ist deren relativ teuere Herstellung. Um diesen Herstellungsaufwand zu verringern, wird vorgeschlagen, die geometrie des Stanzniets in Verbindungslängsachse nicht rotationssysmmetrisch auszubilden. Zum Herstellungsverfahren wird vorgeschlagen, ein Stabprofil zu einer gewünschten Geometrie auszuformen und dann die Stanznieten vom Stabprofil abzulängen.

A method for manufacturing an anchor rivet is provided to increase productivity and to minimize a defective rate simultaneously. A method for manufacturing an anchor rivet includes a step of cutting a cylindrical material shorter than length of the anchor rivet(S1); a step of forming a cutting groove which is shorter than a cutting groove of a finished product, by using a punch after inserting the cut material into a mold(S2); a step of extending the length of the cutting groove and reducing the length of slit width for the cutting groove, by increasing the length of the body unit by inserting and punching a semi-finished product into the mold with a smaller diameter(S3); a step of extending the length of the body and forming an insertion hole inside the body simultaneously, by inserting and punching the semi-finished product into the mold(4a) with the smaller diameter(S4); and a step of finishing a head at a rear end portion by inserting and punching the semi-finished product into the other mold(4b)(S5).

PURPOSE: A device is provided to produce the end of a stainless forging rivet in a round shape for a convenient use and to form a hole. CONSTITUTION: On operating a header machine, a material(30) is cut and stops in front of a first metal mold(9). Then, the material is inserted into an insertion(5) of the first metal mold by a punch(14) and a pin(6) to form a hole. A second punch(3) moves to the first metal mold and an operating bar(8) of the first metal mold pushes the material. The material is inserted into an insertion(2) of the second punch. The ends(1)(7) of the insertions are in a round shape so that the end of the material is in a round shape. The insertion is prevented from being narrower by a hole supporting bar(12) of the material. The second punch returns back and the hole supporting bar pushes the material. Therefore, a stainless forging rivet is finished.
