Definitions

  • the invention relates to a straightening machine for wire, in particular for reinforcing steel wire, with a housing which is driven to rotate about its longitudinal axis, with a plurality of straightening nozzles which are radially offset from the longitudinal axis, and with an actuating device for radial adjustment of the straightening nozzles, the straightening nozzles each in a directional nozzle holder are rotatably mounted and the directional nozzle holder are arranged axially fixed in the housing and radially movable to the longitudinal axis of the housing (see for example FR-A-2 312 314, from which the invention is based).
  • the wire is drawn off from a coil, straightened through the straightening machine, cut to length and fed as a straight round steel rod for further processing and / or use.
  • the straightening nozzles in such a straightening machine are ring-shaped closed nozzle-shaped components made of wear-resistant material, e.g. made of hard metal.
  • the nozzle diameter of the straightening nozzles is larger than the wire diameter of the wire to be straightened and is chosen so that the wire thickness can vary within a predetermined wire thickness range, for example between 6 and 16 millimeters.
  • the end of the ring nozzle holder is designed as a threaded pin which engages in adjusting nuts which are rotatably mounted on the housing.
  • the adjusting nuts have toothed rings on the outside and can be actuated via threaded spindles which are arranged parallel to the longitudinal axis in the housing.
  • the actuator for radial adjustment of the directional nozzles is structurally complex, especially since clutch devices that can be engaged and disengaged must also be provided. Groups of ring nozzle holders can be adjusted radially together, the actuating movement of ring nozzles coupled to one another always taking place in the same direction around the same actuating length.
  • a straightening machine is known from GB-PS 711 991, the straightening nozzles of which are individually adjustable. Radial adjustment of the straightening nozzles enables straightening of wires with different wire diameters. Since all directional nozzles have to be adjusted individually, switching to other wire diameters is time-consuming.
  • the invention has for its object to provide a straightening machine of the type described above with which wires with different wire diameters can be processed one after the other, the required radial adjustment of the straightening nozzles being possible in a simple and automatic manner while avoiding individual adjustment work on the individual straightening nozzles.
  • the invention teaches that the actuating device has two thrust elements which are arranged in the housing in such a way that they can move axially and in pairs, that the thrust elements have wedge surfaces on sections assigned in the radial direction, the wedge surface pairs form from parallel aligned wedge surfaces, and that the directional nozzle holder between the wedge surfaces of the wedge surface pairs are supported slidably.
  • An axial adjustment of the thrust elements is transferred via the wedge surfaces to the directional nozzle holders, which execute a more or less large radial movement in accordance with the wedge surface angle.
  • the straightening nozzles When straightening wire, the straightening nozzles have a straightening nozzle-specific radial offset to the longitudinal axis of the housing, which differs in amount and direction from the straightening nozzle to the straightening nozzle.
  • the wedge surface pairs assigned to the directional nozzles are individually adapted accordingly.
  • the thrust elements consequently have a plurality of differently designed wedge surfaces in the longitudinal direction, the wedge surface angles of which differ in amount and / or sign.
  • the radial adjustment of the individual directional nozzle holders is forcibly coupled and can be initiated by axial adjustment of the thrust elements, the adjusting movement of the directional nozzle holder being nozzle-specific in terms of amount and direction, however, depending on the wedge surface angle and can vary from directional nozzle to directional nozzle.
  • the wedge surfaces assigned to the straightening nozzles are set up in such a way that, in predetermined operating positions of the thrust elements, the straightening nozzles have a radial offset from the longitudinal axis of the housing, which allows a wire of a certain thickness to be straightened optimally.
  • the directional nozzle positions can be changed and wires of different wire thickness can be processed one after the other without making individual adjustments to the individual Directional nozzle holders are required.
  • the wedge surface design is preferably selected so that in a first operating position of the two thrust elements, all directional nozzles are arranged without displacement in the longitudinal axis of the housing, that in a second operating position of the two thrust elements, all directional nozzles have a predetermined nozzle-specific maximum eccentricity to the longitudinal axis and that in accordance with the wire thickness of the wire to be straightened, the thrust elements can be moved into further operating positions between the first and the second operating position.
  • the invention teaches that the push elements can be locked in the operating positions.
  • An assembly-friendly embodiment of the straightening machine according to the invention is characterized in that the thrust elements are guided in rails which are inserted between the housing half-shells and screwed to them to form the housing.
  • the thrust elements are guided in rails which are inserted between the housing half-shells and screwed to them to form the housing.
  • the straightening machine shown in the figures is intended for wire, in particular for reinforcing steel wire, which is drawn off from a coil, straightened as it passes through the straightening machine, then cut to length and as a straight round steel bar, e.g. Reinforcing steel rod, which is further processed and / or used.
  • the straightening machine according to the invention enables straightening of wire whose wire thickness varies within a predetermined diameter range, for example between 6 and 16 millimeters.
  • the basic structure of the straightening machine includes a housing 1 which rotates about its longitudinal axis, a plurality of straightening nozzles 2 which are radially offset from the longitudinal axis 3, and in the exemplary embodiment an inlet nozzle 4 which is arranged in the longitudinal axis 3 of the housing.
  • the housing 1 is mounted in a machine frame, from which the bearing points 5, 6 can be seen.
  • the drive takes place via cell belts and a corresponding V-belt pulley 7.
  • the directional nozzles 2 are rotatably mounted in the directional nozzle holders 8, which in turn are arranged axially fixed in the housing 1 and radially movable in relation to the longitudinal axis 3 of the housing.
  • an actuating device is provided with two thrust elements 9, which are arranged in the housing 1 so that they can move axially and in pairs.
  • the two thrust elements 9 have wedge surfaces 10, 11 on sections assigned in the radial direction on, which are aligned parallel to each other and each form a pair of wedge surfaces.
  • the directional nozzle holders are slidably supported between the wedge surfaces 10, 11 of the wedge surface pairs.
  • the design of the wedge surfaces 10, 11 is selected so that in a first operating position I of the two thrust elements 9, all the directional nozzles 2 are arranged without offset in the longitudinal axis 3 of the housing 1 and that in a second, operating position II of the two shown in FIG. 1 Thrust elements 9 all directional nozzles 2 have a predetermined, nozzle-specific maximum eccentricity to the longitudinal axis.
  • the thrust elements can be moved into further operating positions III, indicated by dash-dotted lines, between the first and the second operating position. In the operating positions I, II, III, the thrust elements can be locked by screw bolts 12.
  • the thrust elements 9 are guided in rails 13. 2 that the rails 13 are inserted between the housing half-shells 14 and are screwed to them to form the housing 1. By loosening this screw connection and opening a housing half-shell 14, the directional nozzle holder 8 can be exchanged.
