Definitions

  • the invention relates to a system for straightening, work hardening and subsequent processing of steel wire material wound into coils, in particular for the production of reinforcing steel mesh, according to the preamble of patent claim 1.
  • a system of this type is known from DE-14 52 981-C3.
  • the wire is fed from a coil of wire lying on a reel through a roller straightening device which provides the wire to a stretching device which has a first clamping device arranged in a fixed position and a second clamping device fastened behind it on a movable, motor-driven stretching slide.
  • Behind the stretching device is a transport device and immediately behind it a pair of scissors in which the wire is cut into pieces of the desired length and then placed on a storage table.
  • the stretched wires are processed into reinforcing steel mats, lattice girders, etc. in a separate work process elsewhere.
  • the wire To stretch the wire, it is clamped in the first stationary and in the second movable clamping device and then the second clamping device is moved by a distance corresponding to the desired degree of stretching away from the first stationary clamping device by means of the stretching slide.
  • the wire section between the two clamping devices is stretched and cold worked.
  • the clamping devices are released and the wire is transported so far backwards by means of the downstream transport device, which consists of two conveyor rollers, until the next, not yet stretched piece of wire lies between the two clamping devices.
  • the stretching slide is moved back to its starting position during the transport of the wire.
  • the second clamping device which is at the rear in the transport direction, is designed to be movable, the end section of the wire lying behind the stretching device is displaced during the stretching process and is therefore removed from processing during the stretching process.
  • the cut wire pieces collected on the storage table are therefore supplied in groups to a processing device, such as a lattice welding machine or a machine for producing lattice girders or reinforcement cages, in the transverse wires in the known system , Brackets or other elements are welded on.
  • the object of the invention is to enable direct processing of the drawn wire or a group of such wires before cutting into pieces in a generic system, d. H. integrate a processing device, such as a device for producing a wire mesh, reinforcement cages or lattice girders into the system. In this case, processing on the stationary wire or on the stationary wire sheet should be made possible during the stretching process in the processing device.
  • a processing device such as a device for producing a wire mesh, reinforcement cages or lattice girders into the system.
  • processing on the stationary wire or on the stationary wire sheet should be made possible during the stretching process in the processing device.
  • the second clamping device of the stretching device is arranged in a stationary manner, so that the wire section behind the stretching device is not moved during the stretching process. It is thus possible to process the wire behind the stretching device on the stationary wire during the stretching process.
  • This enables a welded connection to be made or a bending operation to be carried out on the wire section behind the stretching device during the period in which the wire is stretched in the stretching device.
  • It enables the integration of a processing device, such as a grid welding device, into the overall system before the cutting device. This is how the cross-wires are welded on in cycles during stretching a grid belt is made possible, which can then be cut to the desired length by the cutting device. As a result, the performance of a plant containing a stretching device and a processing device can be increased considerably.

  • the adjustable stroke with which the clamping device 6 can be moved back and forth between the positions shown in FIG. 1 by means of the stretching slide is designated by the reference number 9.
  • a transport device 10 is arranged behind the stretching device 5, by means of which the wire 8 can be pulled out of the stretching device 5 and out of the drain device 1 in cycles.
  • the transport device 10 is designed as a device which in each case conveys the wire by an adjustable, precise stroke.
