Definitions

  • the present invention relates to a device for placing one or more layers of a plurality of metallic wires, the direction of which changes continuously during the stranding, on the surface of elongated material, in particular of electrical cables or lines, by means of a hollow nipple rotating with changing direction of rotation whose tapered outer surface runs the wires in guide grooves evenly distributed around the circumference and in the bore of which the cable core is guided.
  • This disc carries out an oscillating movement, so that the individual wires, in cooperation with the stranding nipple, are deformed in a wave shape and then placed on the cable core or embedded in a mass located on the core.
  • the concentric conductor is held by a special guide nipple until a copper helix is applied.
  • the disadvantage here is that there must always be an adhesive mass as a base and a correspondingly long guide to prevent the concentric conductor from falling off the soul. Because there is no roping by the leader. Such a mass is often undesirable, e.g. B. in the manufacture of cables for high and highest voltages or reinforcements for any strand-like material.
  • the invention has for its object to improve the device known from DE-A-2 705 743.
  • the hollow nipple is provided with guide grooves only at its end facing the run-up point of the wires on the surface of the material and at the end facing the entry of the cable eggs into the hollow nipple is releasably connected to an annular plate, which has holes arranged for the wires in one or more pitch circles, and that the angle of inclination of the outer surface of the circumferential hollow nipple to its central axis and thus the angle of inclination of the wires running along this surface to this axis 5 to 20 °, preferably 10 to 15 °, and the radial distance between the outlet point of the wires from the end of the circumferential hollow nipple and the surface of the material passing through is between 0.3 and 2.0, preferably 0.8 and 1.5 mm.
  • the wires are properly guided shortly before being placed on them.
  • the individual wires are positioned correctly and evenly on the circumference, e.g. B. distributed the cable.
  • the annular plate with the holes for the wires and the hollow nipple with guide grooves provided at the end form a functional unit. Since these parts can be detached from one another, the structural design and the production of these parts are considerably simplified, but setup times can also be saved considerably if, as is the rule, different core diameters are provided with a wire layer by means of the device according to the invention.
  • a certain number of individual wires is required.
  • a certain number of individual wires can be assigned to different cable core diameters. Since the hollow nipple and the annular plate are detachable parts, an annular plate with a fixed number of holes for the individual wires can be assigned several hollow nipples with different holes for different core diameters.
  • An exchange can be carried out in a simple manner if the hollow nipple and the annular plate can be connected by screws. This means that a single plate is required for several wire numbers due to one or more pitch circles, with a hollow nipple matching the inner diameter and the appropriate number of guide grooves being assigned to the respective outer diameter. This possibility not only considerably reduces the tooling effort, but also leads to a significant reduction in the set-up times, since the plate with the bores does not have to be changed constantly and the wires do not have to be drawn into the device again through the entire tool.
  • the bores in the circular plate in one or more partial circles can be marked according to the current number of wires, which saves setup time.
  • the wires are sequentially gripped and held by the tether when the hollow nipple leading the wires z. B. continues in one direction and then changes its direction of rotation.
  • the hollow nipple consists of a hollow cylindrical part and a part adjoining it in the direction of passage of the cable core in the form of a blunt hollow cone. This ensures free feeding of the individual wires to the guide grooves at the other end of the hollow nipple.
  • the guide grooves are covered by a sleeve common to all grooves. Slipping of the wires out of the grooves is prevented, the wires come in the correct, i.e. H. to lie on the surface of the goods at the prescribed distance from one another. This applies even if you go to higher production speeds.
  • the z. B. from an inner conductor, an inner conductive layer, insulation and an outer conductive layer existing cable core 1 runs, as indicated by an arrow, in the hollow nipple 2, which rotates with changing direction of rotation during the passage of the cable core around this.
  • the individual wires 3 are withdrawn from wire supplies (not shown) and guided through guides 4 in the annular plate 5 and guided in the direction of the guide grooves 7 with the cover sleeve 6.
  • the grooves are distributed around the circumference in accordance with the number of wires to be applied.
  • the wires 3 are deformed in a wave shape, thereby being placed on the surface of the core 1 and held by the band 8 which is applied by means of a spinner (not shown).
  • a spinner (not shown).
  • Only one ring-shaped plate is necessary for both of the specified numbers of wires, and for the respective cable core diameter, a diameter-matching hollow nipple 2 with a corresponding Number of guide grooves 7 attached. This possibility reduces the tool effort and the set-up time, since the ring-shaped plate 5 does not have to be changed and the wires 3 do not have to be drawn in again through the entire tool.
  • the detachable connection of the hollow nipple 2 and the annular plate 5 takes place via the screws 9.
  • the hollow nipple 2 consists of a hollow cylindrical part 10 and an adjoining frustoconical part 11 bearing the guide grooves 7 at the end.
  • the hollow nipple 2 Since the hollow nipple 2 is provided with guide grooves only at its end facing the point of contact of the wires 3 on the surface of the material and at the end facing the entry of the cable core into the hollow nipple 2 it is connected to an annular plate which is arranged in one or more partial circles Has holes for the wires, the wires are freely guided from the exit of these holes to the inlet in the guide grooves located at the other end of the hollow nipple. It is therefore not necessary to provide longitudinal grooves on the surface of the hollow nipple.
