    摘要： A method and apparatus for drawing steel wire to produce high tensile strength, steel wire with increased torsional ductility. The wire is drawn through a plurality of standard dies (14) in a wire drawing machine (10̸). The cross section of the wire is reduced by a constant reduction of about 15% to about 18% at each of the standard dies (14) with the exception of the final two dies (18,19). The wire is then reduced by about 10̸% to about 90̸% of the typical reduction at the next to last die (18) and the remainder of the reduction at the final die (19).

    摘要： According to one aspect of the invention, a device for driving a fastening element into a substrate comprises an energy transfer element for transferring energy to the fastening element. The energy transfer element is preferably movable between an initial position and an adjusted position, wherein the energy transfer element is in the initial position before a drive-in process and in the adjusted position after the drive-in process. According to a further aspect of the invention, the device comprises a mechanical energy store for storing mechanical energy. The energy transfer element is then particularly suitable for transferring energy from the mechanical energy store to the fastening element.

    摘要： A wet wire drawing machine (la, 1 b), particularly for drawing very high strength steel wires, comprising: • - a station (2) for unwinding a coil of crude wire (3) from a rotating spool (200), • - a plurality of intermediate drawing stations (4, 5, 6) which are arranged sequentially with respect to each other and are provided with means (7) for the lubrication of at least the drawplates (8) with which they are provided, • - anti-slip pulling means (18) which are associated with the last intermediate wire drawing station (6) for the elimination of irregularities in the wire (19) processed in the intermediate wire drawing stations (4, 5, 6) and for attenuation of the vibrations of the rotating elements of the intermediate wire drawing stations (4, 5, 6), • - a final wire drawing station (24) which is provided with wire straightening means (25) so as to obtain a processed wire (19) having the desired geometric shape and mechanical characteristics, • - a coil winder (33) arranged in output with respect to the final wire drawing station (24) so as to wind the processed wire (19) into a coil (34).
