Definitions

  • the invention relates to a system for rolling wire, in which a wire mill downstream of a cooling section, comprising successive conveyor sections for transporting the fanned out on the conveyors to turns wire, and a wire turns from the cooling section decreasing and dropping into a coil forming device drop-in conveyor.
  • both thin wire - with diameters up to about 20 mm - and thick wire - with diameters up to about 50 mm - after exiting the multi-stand finishing mill of a rolling mill are subjected to different cooling processes.
  • These include for thin wire, the so-called Stelmor products, and thick wire, the so-called Garrett products, either a standard or forced cooling, e.g. for medium to high carbon carbon steels and austenites, delayed cooling, for example for low carbon C steels, helical steels, spring steels and welding wires, or slow cooling, e.g. for tool steels and high speed steels.
  • These conditions can be created by a correspondingly designed cooling section.
  • the wire rolling mill of these known systems downstream of a coil forming device is connected downstream of the cooling section, in which the wire turns of an infeed conveyor, which is arranged as a bridging member between the last conveyor section of the cooling section and the bundle forming device, are dropped.
  • the wire bundles thus obtained are removed, e.g. supplied with a hook path of a Ringpreß- and binding station, and further distributed from there.
  • the well-known in-feed conveyor as a conveyor z. B. roller table rollers, of which at least some are driven, conveyor belts or transport chains, are anchored stationary with the foundation.
  • Bunderelievoriques they are assigned as a separate part of a stub roll segment, which surrounds the Bundstoryevortechnik partumflindlich and has pairwise, spaced opposite stub rolls.
  • the stub roll segment is adjustable in different directions of movement and indirectly it is also the stub rolls. This is intended to enable a more targeted ejection of the wire rings into the framing device.
  • This purpose is also the stub roll, which are not one-piece continuous, but rollers with a certain part length. In each case a pair of opposing stub rolls has the same part length, these part lengths from pair of rollers to pair of rollers towards the framing device are shorter.
  • the invention is therefore an object of the invention to provide a generic system without these disadvantages, in particular to allow undisturbed transport with safe forwarding of the turns of wire from one to the other transport route and to improve the insertion of the wire turns in the Bundsentevorraum.
  • a proposal of the invention provides that the infeed conveyor is arranged ascending in the conveying direction and with a rear, facing away from the collar forming device end portion under a last conveying section of the cooling section is submersible slidably.
  • the thus graded transfer and the subsequent rising transport path improve the dropping or insertion requirements and allow it to work at different speeds.
  • the insertion and passage of the wire turns in the coil forming device is further improved by the fact that the last conveyor section of the cooling section is also formed with pairs, each other at a distance opposite stub rolls.
  • the infeed conveyor on fixed guides, e.g. Rails or the like running surfaces, is arranged.
  • the insertion conveyor can be positioned exactly by displacement, it is proposed that it is formed with at least one linear drive.
  • the linear actuators which are controlled in a path-controlled manner can be hydraulic, mechanical or electromechanical adjusting means. It can z-B. Racks, pinion combinations, ropes, chains, timing belts, helical gears or the like are used.
  • a wire rolling mill is followed by a cooling section 1 and this as a bridging link to a collar forming device or chamber 2 as an infeed conveyor 3 designed as a roller table conveyor (compare Fig. 5).
  • the cooling section 1 consists of several, covered by hoods 4, covers or the like conveyor or roller table sections 5 with numerous successive, mounted in a support frame roller conveyor rollers 6, of which at least some are driven (see Fig. 3), and in the embodiment one in the conveying direction according to arrow 7 last, solid conveyor or roller table section 8 with stub rolls 9 arranged therein; these could alternatively be designed continuously.
  • the wire rolled in the multi-stand wire rolling mill is fed behind the last stand and, after passing through, for example, a water box and subdivided by a pair of scissors, from a coiler in the form of helical windings 10 (see Fig. 2) the roller table rollers 6 stored. From the cooling section 1 enter the wire turns 10 for further transport on roller table rollers 11, some of which are driven, the infeed conveyor 3. About the transport end side front end they are inserted or dropped into the chamber-like coil forming device 2, wherein a mandrel 12 (see Fig. 5) the wire turns to a finished Centered collar.
  • the infeed conveyor 3 is linearly displaceable in the direction of the double arrow 13 (see FIGS and 5) on stationary guides 14 (see Fig. 3).
  • the infeed conveyor 3 can thus be positioned in relation to the last roller table section 8 of the cooling section 1 on the one hand and the coil forming device 2 on the other hand by linear displacement exactly and in particular without gap to the cooling section 1.
  • Fig. 4 an embodiment is shown, in which the infeed conveyor 3 is formed at a slight angle in the conveying direction 7 as slightly rising as the cooling section 1 and with its rear, facing away from the Bundsentevoruze 2 end portion 15 to below the last roller table section 8 of the cooling section 1 is moved.
  • At least one linear drive 16 acts thereon, as shown in FIGS. 1 and 5, which can be constructed in a variety of ways, e.g. hydraulic, mechanical or electromechanical, can provide.
  • a stub roll segment 17 fixedly connected to the infeed conveyor 3 is arranged at the front end of the infeed conveyor 3 in the discharge area for the bundle forming device 2.
  • This has in paired arrangement opposing stub rolls 18a to 18d, each stub roll 18a to 18d of a pair of rollers in a separate role segment half 19 and 20 is stored.
  • the roller segment halves 19 and 20, respectively, are slidably mounted transversely to the conveying direction 7 on the insertion conveyor 3 in accordance with the double arrow 21 (see FIG.
  • roller segment halves 19 and 20 are adapted to the contour of the collar forming device 2 and include these on both sides partially circumferentially to about the center plane, as shown in Fig. 4.
  • Fig. 2 it can be seen that the opposing stub rolls 18a to 18d in the transport direction 7 and thus to the discharge area of the collar forming device 2 towards gradually become shorter, ie the first stub rolls 18a are longer than the following in the transport direction 7 stub rolls, the last stub rolls 18d are the shortest.
