Definitions

  • the invention relates to a method and an apparatus for manufacturing high-strength steel wire strands, especially of steel cord, which in The preamble of claims 1 and 6 respectively indicated Smoothing.
  • Double twist stranding machines e.g. according to DE-OS 24 62 092 since several years also used for the stranding of steel wires.
  • the individual winding spools are aligned one behind the other each arranged between gear stands. Every single one Wire is fed around the coils into the center of the axis by roller systems Rotor and from there through a bearing pin to the next coil frame where it is connected with the wires to be added in the previous described way is forwarded.
  • the wires are at the rotor end via a deflection roller that rotates synchronously with the rotor in the opposite direction deflected and in a sinusoidal curve around the coils in each case out the other end of the rotor.
  • the first stranding point lies in the area of the first Deflection pulley and the second stranding point for realizing the double lay is located at the end of the stranding machine.
  • the machine can only manufacture hollow strands in accordance with quality will.
  • This machine is used for the production of strands with core wire not suitable, since the core wire approximates its length during the stranding maintains and is therefore longer than the wires of the top layer, the is shortened by the second stranding twist and the result is a disadvantageous Deformation of the strand causes.
  • the Spool volume of all payout spools is usually a multiple of Spool volume of the take-up spool.
  • DE-OS 1510091 describes a method for transmitting a rotary movement from one to the other other outer part of a thread-like element with two different ones around the axes measured speeds as well as a machine for stranding elements after the mentioned methods have been disclosed.
  • These as both out-in and as Stranding machine designed in-out has several stranding stations, each with one rotary driven stranding bracket, which is rotatably mounted on both sides
  • the drain or take-up spools are stored in a cradle within the stranding bracket.
  • the desired twisting of the rope can be realized by a large number of guide elements on the Stranded brackets arranged to exert a force component on the thread-like element.
  • the arcuate rope parts have a minimal arc radius.
  • the executive bodies are "inclined" to the longitudinal direction of the rope and can be pivoted via bearing blocks on the stranding bracket arranged and designed as diabolo-shaped rolls.
  • the invention is based, a highly productive double twist stranding machine to develop in-out according to the principle Help also steel wire strands with core wire quality and without that Disadvantages of the prior art can be produced.
  • the advantages achieved with the invention are that a wide Production program including steel wire strands with core wire in line with quality can be manufactured and the requirements of the user industry after simple operation also several stranding machines by one Operator can be satisfied by constantly changing the take-up reels (Removal, loading) during the entire stranding process, i.e. the continuous stranding of the stranded material of the pay-off spools can be.
  • the stranding concentrates on a point in the area in front of the first deflection roller, the management of the bandage or the strands designed in this way is that the entire dressing rotates about its longitudinal axis, at twice the speed of the rotor.
  • the stranding has already in the area between the payout spool and the pulley twice the speed (stranding speed) of the rotor, so that the stranding already immediately after the Deflection pulley has its final twist speed (double) and on the way to the second pulley is only guided and maintained.
  • An essential means here is the conically shaped pulley.
  • the stranding device shown in Fig. 1 contains a double twist stranding machine 1, in the rotating system of which several spools 3 one wire brake 2 each mounted in a common coil frame 1a are.
  • the coil frame 1a is around the end hollow pin 1b, 1c Center axis M rotatably mounted, but rotates due to its own weight not during the stranding process.
  • the stranding machine 1 are one Double disc take-off 4 and a winding station with a laying device 5 subordinate.
  • a possibly hollow pivot conical deflection roller 6 mounted, the longitudinal axis of which is substantially vertical runs to the central axis M.
  • This deflection roller 6 forms a first Deflection point for the stranded material drawn off together by the run-off rollers 3, that - as shown in Fig. 2 - runs on its largest diameter part and during the deflection on their jacket to the narrower end part slides down by twisting. Due to the effect of the conical pulley 6 experiences that formed by the individual running wires 7 Stranded a complete stranding, the first and second stranding twist be united in a stranding point 8. As shown in Fig.
  • a flyer 10a and 10b is mounted at each end of the coil frame la, which each have a conical holder with one arranged on its edge Deflection or guide element 11a, 11b in the form of a roller or a nipple exhibit.
  • the pulled off from the narrower end part of the deflection roller 6, now in its structure finished steel wire strand 9 runs to the guide element 11a of the first flyer 10a and from this in a free flight arch the guide element 11b of the second flyer 10b to one in the bearing journal of the second flyers 10b transverse to the central axis M deflection roller 11c.
  • the Both flyers 10a, 10b are sent together via suitable gears, e.g. Timing belt drives, driven synchronously by a drive unit, not shown, the being in or on the hollow journal of the first flyer 10a mounted conical deflection roller 6 together with the flyer 10a around the Center axis M rotates.
  • the wire pull brake 2 shown in FIG. 3 is a so-called dancer-controlled Brake executed and contains a two-armed pivot lever 2b, on the one arm the operating roller 2b wrapped in the running wire 7 is mounted and engages a spring 2c at the other end.
  • the the Actuating roller 2a carrying lever arm is connected to a push rod with a lever-like brake shoe 14 connected, the brake pad 16 against the braking surface 15 a brake disc attached to the shaft of the payout spool 3 13 presses.
  • the braking surface 15 is preferably chrome-plated, ground and polished and has a roughness of less than 3.2 pm.
  • the braking or The friction lining 16 of the pivotable brake shoe 14 suitably consists of tetrafluoroethylene with a carbon content of about 25%.
  • Double disc trigger 4 contains two axially parallel with spacing mounted rollers 4a, 4b, of which at least one roller 4a with circumferential grooves 4c can be provided. At least one of these roles has one Level 4d.
  • the steel wire strand 9 runs in several orderly loops around the two rollers 4a and 4b and experienced by the jump caused by level 4c from the smaller to the larger roll diameter a defined increase in tractive force due to the torsional stresses be dismantled in the strand.
  • a post-forming device 17 is provided which has at least one row of Straightening rolls arranged one behind the other with mutual dislocation has, their mutual transfer according to the respective product and Operating conditions can be set.
  • the steel wire strand 9 runs in a wavy path over the rollers, and through the resulting Bending and flexing effects result in stress relief and position corrections of the stranded wires.
  • the steel wire strand 9 is the laying device 5 of the Winding device supplied, which is shown in Fig. 5 in detail and includes a rotatably driven and laterally movable coil package 18. Since the spool volume of the payout spools 3 is many times larger than the spool volume of a take-up spool 19 is in the spool package 18 so many take-up reels 19 axially arranged side by side that their total volume corresponds at least to the total coil volume of the supply coils 3. 5 and 6 are arranged axially one behind the other Take-up spools 19 deflection and centering disks 20 arranged, whose outer diameter is larger than that of the coil flanges 21. The Deflection and centering disks 20 have slightly conical recesses 22 Bracket each on a coil flange 21.
  • the take-up spools 19 and the deflecting and centering disks 20 are through an axis 24 freely protruding through its central bores, the each end with a support flange 23 and screw connections 25 at the end is provided.
  • Both ends of the axis 24 represent the counterparts of the rewinder receptacle 26 are arranged in a frame 27 and with a rotary drive and a displacement device are connected.
  • the transfer elements 28 are sawtooth-like and limited execution.
