Definitions

  • the invention relates to a method and an apparatus for producing single and multi-layer steel wire strands, in which the individual wires are drawn off from stationary drainage systems arranged outside the stranding device and stranded without turning back according to the indirect double lay stranding principle, i. that is, the strand is ready in its exact geometric shape before reaching the rotating system with trigger and rewinder.
  • the currently most commonly used form for the production of steel wire strands is the stranding of wires on high-speed stranding machines.
  • the quality of the strands produced on these machines is good.
  • the productivity of the high-speed stranding machines is mainly determined by the speed of the elongated stranding rotors. Due to the constant technical improvement of this assembly, including its storage, rotor speeds have now been reached which strain the available materials to their permissible limit, ie further increases in speed and thus increases in performance of the fast-stranding machines are no longer possible. An attempt has therefore been made to use the double-lay principle which is frequently used for stranding plastic materials such as copper and aluminum.
  • this device Compared to a high-speed stranding machine, this device enables significantly higher stranding speeds, and at the same time the mechanical engineering effort drops considerably.
  • the main disadvantage of this method is that the twisting is based on the previously known double lay principle, ie the entire twisting is not concentrated in one point. As a result, exact compliance with the stranding geometry and compliance with constant length ratios and thus uniform load capacity of the wires in the individual layers of the stranded strand are not guaranteed.
  • DD-A-143 279 it was therefore proposed to use a turning device to carry out the stranding before the double-twist stranding machine. The two different stranding points of the double lay principle are concentrated in one point.
  • the aim of the invention is to produce single and multi-layer steel wire strands with the least mechanical engineering effort, with minimal space requirements for the equipment, in high quality, in particular compliance with the exact geometry of the strand.
  • the invention has for its object to develop a method and an apparatus for producing single and multi-layer steel wire strands, in which the strand according to the indirect double-twist principle is completed before entry into the take-off and take-up device in its exact geometric structure and torsional stresses are reduced and this condition is maintained exactly on the way of the strand leading up to the rewinder.
  • the object is achieved in that the individual wires are drawn off in a known manner from stationary drain systems arranged outside the stranding device, stranded in layers in succession, identical stranding sections arranged in accordance with the indirect double-twist stranding principle, and fed to the take-off and rewinder arranged within the rotating system, in accordance with the invention the wires of each corresponding position within the associated stranding section individually via a braking device and according to their later arrangement in the assembly of the finished stranded wire through an associated stranding disk at a very narrow angle of 10 - 20 ° over one at the associated stranding point arranged guide pin with coaxially arranged stranding nipple and an associated twisting device and then the strand, finished in its geometrical shape, is guided to a further twisting device and then via specially arranged and executed guide and deflection rollers to the take-off and rewinder.
  • both the twisting devices and the rotating system have the same direction of rotation
  • the twisting devices of the individual stranding points are in synchronization with one another and rotate at twice the speed of the rotating system
  • the last twisting device in front of the rotating system is a function of the strength of the stranded material 10 - 25% higher speed than the twisting devices of the individual stranding points.
  • the device according to the invention for the production of single and multi-layer steel wire strands according to the indirect double lay stranding principle is known to consist of stationary drainage systems arranged outside the stranding device, corresponding to the number of layers in the stranding direction one after the other identical stranding sections and a rotating system to which a take-off and a winder are assigned, whereby according to the invention
  • Each individual stranding section immediately before the stranding point corresponding to the number of wires to be stranded, braking devices and a stranding disk designed in a known manner and furthermore in the stranding direction in the stranding point a guide pin with coaxially arranged stranding nipple and an associated twisting device are allocated between the stranding sections and the rotating system Twisting device and within the rotating system to maintain the exact geometric condition of the strand in Abha tightness of the direction of rotation at an angle by Max.
  • each brake device consists of a pair of rollers which are wrapped several times by the associated wire and braked by any known brake, each roller having V-shaped grooves with an opening angle ⁇ of 60 °, the guide pin at the respective stranding point with a Cone is provided at an angle ⁇ of 10 - 20 ° and has grooves for guiding each individual wire, the grooves are arranged at an angle of 15 ° according to the direction of rotation and at the end have a radius that is 10 - 20 times larger than that stranded wire diameter.
  • the stranding nipple arranged coaxially to the guide pin has a bore in the stranding direction with a diameter of 1.2 to 1.3 times the strand diameter
  • the inlet radius of the stranding nipple corresponds to 30 to 50 times the wire diameter to be stranded
  • the distance between Guide pin and stranding nipple can be adjusted depending on the diameter of the wires to be stranded.
  • four rollers with V-shaped groove profiles, over which the strand is passed, are arranged in all twisting devices, the opening angle ⁇ of the groove profile being 60 °.
  • each guide and deflecting roller within the rotating system has trapezoidal grooves with a cylindrical base, which are made of unhardened, wear-resistant material.
  • each individual stranding section 3 is immediately in front of the stranding point 7 corresponding to the number of wires to be stranded 2 braking devices 8 to give the wires 2 the required retention force and a stranding disk 9 executed in a known manner and furthermore in the stranding direction at the stranding point 7 a guide pin 10 with coaxial arranged stranding nipple 11 and an associated twisting device 12 assigned.
  • each braking device 8 consists of a pair of rollers wrapped several times by the associated wire 2 and braked by any known brake, each roller having 16 V-shaped grooves 17 with an opening angle ⁇ of 60 °.
  • the strand 14 is guided further through a bore 20 arranged in the stranding direction through the stranding nipple 11 with a diameter of 1.2 to 1.3 times the strand diameter to the twisting device 12 belonging to the stranding system 3, which according to FIG. 1 and 4 has four rollers 21 with a V-shaped groove profile 22, the opening angle ⁇ of the groove profile 22 being 60 °.
  • the strand 14 produced so far is not yet twist-free, ie it would dissolve when severed. For this reason, it is turned over in another twisting device 13 and the torsional stresses still present are reduced.
  • the strand 14, which runs into the rotating system 4, which rotates less than half as quickly as a result of the over-rotation in the last twisting device with high self-rotation, is gem.
  • Fig. 5 is supported by the obliquely arranged guide and deflection rollers 15 in their own rotation, so that the stranded bandage is not broken up by the low twist number at the entry point of the rotating system 4, but is retained in its geometric shape and thus in the required high quality the trigger 5 reaches the rewinder 6.
  • Each guide and deflection roller 15 here has trapezoidal grooves 23 with a cylindrical base, which are made of unhardened, wear-resistant material.
