Definitions

  • the invention relates to a device for winding strip-shaped rolling stock on the mandrel of a reel, in which the first turns by means of one of the turns looping tooth chain, endlessly guided over deflection wheels are held, the deflection wheels with one of the toothed chain corresponding peripheral teeth are provided and at least part of the deflection wheels is driven.
  • Strip casting process wins the winding of hot strips, for example, for temporary storage, more and more meaning.
  • a carousel reel is preferred used because these reelers with great Operational safety can be operated; because leading the beginning of the strip to the winding mandrel is largely trouble-free reachable.
  • winding the strip-shaped rolling stock onto the Reel mandrels pay special attention to the winding of the the first two to three turns, which are non-slip on the Thorn should rest.
  • Belt winders are known for winding cold strip which an endless belt around the pulleys Haspeldorn and thus the turns on it partially wraps around.
  • the belt has no drive and is through Frictional contact carried by the mandrel.
  • Belts and pulleys are arranged on swing-away frame parts, which can be rolled up swung in and swung away after unwinding can.
  • metal cord belts are preferred used, these are rubber or rubber belts with particularly abrasion-resistant surface, the inside with highly elastic steel cables are reinforced.
  • Such straps are operational up to temperatures of 200 degrees C and for low Winding speeds of approx. 1.5 m / sec.
  • a sling known for a cold strip reel which is in the manner of a caterpillar track pressure body rotatably mounted on at least one toothed chain has, which extend transversely to the tooth chain.
  • the Pressure hulls are covered with an elastic material.
  • the well-known belt sling is unsuitable for hot strip because the pressure pieces are not temperature resistant and a discharge from tinder.
  • the well-known facility is therefore only suitable for cold strip.
  • wire link strips made of round or flat wire, made of chrome-nickel steel are made. These link bands wear out because of the high mechanical load on the deflections, in particular at high speeds very quickly, whereby Winding speeds of approx. 0.5 m / sec. the upper limit represent.
  • the temperature load of such wire link belts should not exceed 400 degrees C.
  • All of the winding devices described above are only for relatively low winding speeds and limited Suitable temperature ranges and have, especially for do not enforce the rough operation in hot strip rolling mills can.
  • the service life of the known pressing devices is extremely low and is given as 1 to 2 weeks.
  • Wire link belts are their pollution by the accumulating Tinder. This requires extensive maintenance of the link belts, if the service life specified above is to be achieved. Also the wire link belts are sensitive when using belts different widths must be rolled; because they are not suitable for absorbing lateral forces. Preferably should when using these wire link belts, the bandwidth is larger than the belt width, which is a frequent change of belts required when rolling strips of different widths makes. Also the jerky acceleration on contact with the mandrel for the life of the wire link belts disadvantageous.
  • the invention proposes that the tooth chain with a loosened tab link with several arranged side by side and by spacers spaced chain parts that one form a common strand, with the chain links on the the side facing to be wound smooth and on the the side facing the deflection wheels are toothed.
  • Such a tooth chain for example made of heat-treated Chain steel, is highly heat-resistant and wear-resistant.
  • the smooth side of the tooth chain protects the belt surface, whereby by driving the idler wheels one with the incoming one Band or the mandrel synchronous speed is adjustable. As a result, relative movements between the tooth chain and the belt surface, which could lead to wear avoided.
  • the back of the tooth chain i.e. the one to be wrapped up
  • the side facing the belt is almost rigid, but can be moved over the large mandrel diameter of the coiler mandrel can be bent well. In the opposite direction, the tooth chain is easy to turn, so that it can be guided over the toothed deflection wheels.
  • the proposed tooth chain is for speeds up to 6 m / sec.
  • the tooth chain according to the invention increases the life of the Winding device essential, and that for about 2 years.
  • 1 denotes the carousel reel, the two Has reel mandrels 2 offset by 180 degrees, of which only one is shown.
  • the from the driving roller set 3 through the Threading device 4 inserted band 5 is in the area of the coiler mandrel 2 transported and there between the coiler mandrel and the tooth chain partially wrapping around the reel mandrel 2 6 headed.
  • the toothed chain 6 is around toothed deflection wheels 7a to 7d, of which the deflection wheel 7e is driven.
  • the deflection wheels 7a to 7c are on a common lever 8 arranged, the pressure medium-operated 9 is pivoted away.
  • the Deflection wheel 7e remains stationary.
  • the tooth chain 6 is cut out in the Side view shown, it consists recognizably of the Chain links 10, the plates 11, the chain links 10 are bolted at 12, is connected.
  • the chain links 10 are smooth on one side of the tooth chain 6 and with the tabs 11 designed flush while on the opposite Page the chain links 10 are toothed at 13. With these Toothings 13 engage the toothed chain in the corresponding circumferentially toothed deflection wheels 7a to 7e, as later is described.
  • FIG. 3 shows a top view of a flap bandage Tooth chain according to the invention, with the tabs being recognizable in each case 11 are arranged centrally between two chain links 10 and held at a distance by spacers 14 on the bolt 12 are.
  • Figure 4 shows a section through the tooth chain according to the invention 6 in the area of the deflection wheels 7e. These are on the common shaft 15 held at 16 and torsion via the spur gear 17 from a bevel gear 18, which is connected to a geared motor 19, driven.
  • the deflection wheels 7e are provided with a circumferential groove 20 and also toothed at 21 at its circumference. While the teeth 13 of the chain 6 engage in the toothing 21, the Tabs 11 in the groove 20 of each guide wheel 10e, so that a lateral offset of the tooth chain 6 is prevented.
  • the entrainment takes place via the teeth 21 of the deflection wheels 10e and the teeth 13 of the chain 6 at a speed that the infeed speed of the belt or Winding speed of the mandrel corresponds.
  • the tape is shown in Figure 4 at 5; the tooth chain is recognizable out of 4 adjacent to band 5 Chain units, each chain unit according to Figure 3 is executed.
