In a method of making screws, rivets or similar objects from a metal wire (6) the wire (6) is moved through a stationary cropping bushing (14) forwardly to a movable cropping bushing (24) present in a receiving position, following which the movable cropping bushing (24) is moved away from the receiving position substantially transversely to the axial direction of the wire to release a blank from the wire (6). The movable cropping bushing (24, 25) is then moved together with the released blank (26) further on to a discharge position, in which a punch (27) is adapted to move the blank (26) partly into a die (16) and to compress the blank (26) sufficiently to pre-upset it by cold flowing in the region between the die (16) and the movable cropping bushing (25). In an apparatus of making screws, rivets or similar objects the movable cropping bushing (24, 25) is secured to a transport device (15), by means of which it can be moved from a receiving position opposite the stationary bushing (14) to a discharge position opposite a die (16) between said die and a punch (27), which is adapted to move the blank (26) partly into the die (16) and to compress the blank (26) sufficiently to pre-upset it by cold flowing in the region between the die (16) and the movable cropping bushing (25). | ||||||

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

An aluminum-alloy article such as a fastener 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. | ||||||
114 | Fatigue resistant, fluid tight rivet assembly | US09915245 | 2001-07-25 | US20010052178A1 | 2001-12-20 | Ralph Luhm |
The present invention comprises aluminum solid rivets and methods of manufacturing aluminum solid rivets for aircraft and other demanding applications to provide rivets with high strength and excellent driveabiltity while improving the rivets' resistance to fatigue and stress corrosion cracking. In accordance with the method, an aluminum rivet blank approximately the same diameter as the head of the finished rivet is used. This rivet blank is forced into a die to extrude the tapered region and the shank of the finished rivet. The fabrication process provides more uniform cold working at the junction of the shank and the tapered region of the rivet, and better orients the flow lines in this region. The process also can provide a superior surface finish, and may be suitable for use in wet wing fabrication without further processing for improved surface finish. Alternate embodiments are disclosed. | ||||||
