    Abstract: An apparatus to produce a self-piercing and clinch nut includes a first forging die assembly, a second forging die assembly, a third forging die assembly, a transfer mechanism, and a controller. The first forging die assembly subjects a blank to first processing. The second forging die assembly is adjacent to the first forging die assembly, and subjects the blank, which has undergone the first processing in the first forging die assembly, to second processing. The third forging die assembly is adjacent to the second forging die assembly, and subjects the blank, which has undergone the second processing in the second forging die assembly, to third processing. The transfer mechanism transfers the blank between two adjacent forging die assemblies among the first to third forging die assemblies. The controller controls operations of the first to third forging die assemblies and the transfer mechanism.

    Abstract: A self-drilling expansion fastener is integrally formed of a sheet metal material for locking two or more sheet workpieces together, and includes an expansion structure and a drill structure. The expansion structure has a plurality of internal threads and force-distributing bars. The drill structure has a chip guard for covering a head of the expansion structure, and a drill forward projected from the chip guar for self-drilling a hole. When an externally threaded element is screwed into the expansion structure to mesh with the internal threads, the force-distributing bars are brought to expand outward and are finally compressed into a folded state to thereby tightly lock the sheet workpieces to one another. A method of forming the self-drilling expansion fastener is also disclosed.

    Abstract: An Archimedean screw comprising a spiral helix. The Archimedean screw is characterized in that it further comprises a central element plastically twisted like a helix about a central symmetry axis. The spiral helix, in turn, is wound about the central element. Furthermore, the central element is the only supporting element of itself and of said spiral helix.

    Abstract: A thread-producing nut for a screwed connection, wherein a core hole which is provided with thread turns is designed for positively locking, frictionally locking and releasable connection to an, in particular, cylindrical bolt or pin, in such a way that the thread turns have completely formed thread turns in certain sections when viewed in the circumferential direction and that free spaces with thread turns which are formed incompletely in terms of their height are provided between the completely formed sections of the thread turns. Furthermore, a blank for manufacturing the nut and a screwed connection composed of such a nut and a bolt are disclosed herein.

    Abstract: The invention is directed to a method for caulking a caulking member such as a caulking nut or a caulking bolt to a metal plate. The metal plate is arranged on a die having a caulking protrusion formed on an end surface thereof, the caulking member is arranged on the metal plate while a position of a caulking recess portion of the caulking member is aligned with the caulking protrusion, and a punch is brought closer to the die so that the caulking member is pressed against the metal plate. While an upper surface of the metal plate in a position opposite to the caulking recess portion is restricted by a downward protruding portion of the punch or by the caulking member, the metal plate is plastically fluidized into the caulking recess portion, so that the caulking member is caulked without boring a hole in the metal plate.
