Definitions

  • the invention specifically relates to a method for coupling the initial windings and / or windings of a wire bundle in the course of fanning out wire rod to be bundled behind the finished block of a wire rolling mill to which a winding layer for the wire, a roller table, a main conveyor and a collecting mandrel are connected, wherein the winding layer works on the roller table and the roller table on the main conveyor running at a predetermined main conveying speed and the collecting mandrel receives at least one wire bundle, the wire being fanned out in turns on the roller table and the turns being transferred to the main conveyor, on which the treatment is fanned out Winding of the wire takes place, the initial turns and / or end turns also being coupled on the main conveyor.
  • a water cooling section can be arranged between the prefabricated block and the winding layer.
  • the cooling on the main conveyor is generally, but not necessarily, controlled cooling with metallurgical purposes. Coupling is carried out with suitable auxiliary devices, but is still carried out by hand today.
  • the wire In a bundle of wires that is brought to the market, the wire must start from the beginning meet quality requirements and tolerances to the end. Couping must be carried out accordingly accurately and in spite of the high rolling speed of modern wire rolling mills. It goes without saying that the required measurements are connected upstream of the coupé and that the measurement results are taken into account during the coupé.
  • roller table of about 1 to 2 m in length is arranged directly behind the winding layer. Behind the roller table follows the main conveyor in the direction of transport of the wire, the z. B. is designed as a chain conveyor. The purpose of this roller table upstream of the main conveyor is to prevent the wire tip emerging from the winding layer from getting caught at the beginning of a rolling process.
  • the roller table is designed accordingly.
  • the invention has for its object to carry out the method described above so that the coupling of the initial turns and / or end turns and the removal of the cut initial turns or end turns can be done without difficulty.
  • the invention is further based on the object of specifying a system with which the method according to the invention can be carried out in a particularly simple manner.
  • the invention teaches that the roller table is operated at a roller table speed which is greater than the main conveyor speed when the initial turns and / or end turns of a wire bundle to be formed emerge from the winding layer, the wire windings being deposited on the roller table with a coupling fan , which is larger than the treatment fan, that the roller table is switched to the main conveyor speed as soon as or before the first of the windings designed with a coupier fan reaches the main conveyor and the windings designed with a coupier fan are handed over to the main conveyor, and that the couping is carried out on the main conveyor in the area of the coupier fanning out of the turns, - while the following turns on the roller table are again laid out with treatment fanning out.
  • the increased roller table speed for depositing the windings with coupier fan out can be changed depending on the product. It is understood that in the context of the invention, the couping can be carried out by hand. According to a preferred embodiment of the invention, however, the couping takes place automatically with auxiliary devices as described at the beginning.
  • the invention also relates to a plant for carrying out the method according to the invention, as characterized in claims 4 and 5.
  • the system shown in the figures for the implementation of the method according to the invention works behind the finishing block 1 of a wire rolling mill which adjoins on the left.
  • it consists of a water cooling section 2, a winding layer 3 for the wire, a roller table 4 on which the fanned-out wire turns 5 can be seen, a main conveyor 6 and a collecting mandrel 7 for receiving the turns 5 from a wire bundle 8 to be formed.
  • the arrangement is such that the main conveyor 6 works with a predetermined main conveyor speed that can be set up depending on the product. This has been indicated in FIGS. 1 and 2 by an arrow. It is understood that the main conveyor has a corresponding drive, which has not been marked.
  • the upstream roller table 4 has its own drive. It can be driven for the purpose of coupling initial windings and end windings of a wire bundle 8 on the main conveyor 6 at a roller table speed which is greater than the main conveyor speed set up in each case.
  • the cutting machine 9 is indicated in FIG. 2. Otherwise, the arrangement is such that this increased roller table speed can be switched to the main conveyor speed.
  • a computer which controls the roller table in accordance with the coupling to be carried out in accordance with program and / or measurement data, which has not been drawn.
  • the roller table 4 is operated at the exit of the initial turns 5 and / or end turns 5 of a wire bundle 8 to be formed from the winding layer 3 at a roller table speed that is greater than the main conveying speed.
  • the roller table 4 is switched over to the main conveying speed as soon as or before the first of the windings designed with a coupe fan has reached the main conveyor, so that the windings 5 designed with a coupe fan are transferred to the main conveyor. They are in the order of manufacture in the winding layer.
  • the turns to be cut can be easily and cleanly cut off with the cutting machine 9 without getting caught.
