Definitions

  • the invention relates to a reel for winding metal strip, in particular of rolled hot strip, with a mandrel shaft having a first shaft end, which is rotatably supported by means of at least one bearing provided in the reel frame.
  • a rolling stand In the production of steel sheet passes through a metallic hot strip for the purpose of thickness reductions, a rolling stand or consisting of a plurality of rolling mills rolling mill.
  • a reel In order to wind the metal strip into a collar, a so-called coil, a reel is provided at the outlet of the rolling device.
  • Such a reel has a drive shaft driven by a drive shaft.
  • the mandrel shaft is usually rotatably supported by several bearings in the machine frame of the reel. On the projecting end of the mandrel shaft projecting from the machine frame, the hot strip is wound.
  • the mandrel shaft itself usually consists of a mandrel body, of segments and an axially movable in the mandrel body expansion rod, whereby the segments are spreadable in the radial direction.
  • the drive-side part of the mandrel shaft which is mounted in the machine frame, is coupled at its end with a rotary drive.
  • the wound coils can then be removed in the axial direction, for example by an export carriage, which drives the coil out of the area of the reel.
  • a hot strip reel mandrel may have a mass of more than 10 tons, which requires a correspondingly large hoist with high investment costs. The shunting of the hoist in the area of the reel is cumbersome because the space is often very tight.
  • the invention is provided to fasten the drive-side part of the mandrel shaft by means of a releasable tensioning device in the mounting.
  • a releasable tensioning device in the mounting.
  • This makes it possible in a simple manner, extract the mandrel shaft in the axial direction of the frame of the reel.
  • another mandrel shaft can be inserted via the coil car from the operating side into the storage.
  • the clamping device is tensioned.
  • a frictional connection between the mandrel shaft and the bearing more precisely the inner ring of the bearing, is produced.
  • the mandrel shaft is then fixed in the machine frame and ready for winding the hot strip.
  • the clamping device can be designed differently. According to their type of actuation, they can be actuated both mechanically and hydraulically.
  • the clamping device is designed as a hydraulically operated clamping sleeve. It has, in a preferred construction, a cavity for receiving a hydraulic medium in the form of a hollow cylinder. If this cavity is subjected to hydraulic pressure, there is a radial expansion of the clamping sleeve and as a result thereof in the region of the bearing seat to a radial spread. This frictional connection can be solved again by the hydraulic pressure is reduced and the elastic deformation of the clamping sleeve is formed back.
  • the clamping takes place by means of a mechanical clamping sleeve.
  • the clamping force is generated manually, for example by a shaft nut in conjunction with a conical seat tapered sleeve construction.
  • the clamping by means of a combination of a hydraulic clamping sleeve in cooperation with a manually operated conical seat tapered sleeve construction.
  • the FIG. 1 shows parts of a reel 1 in a highly simplified representation.
  • the reel 1 has a mandrel shaft 2.
  • the mandrel shaft 2 is rotatably supported in a drive-side part 18 by means of two bearings 4 in a machine frame 3.
  • These two bearings 4 may for example be roller bearings, each having an inner ring and an outer ring, wherein the outer ring is fixed by press fit in the machine frame 3 or is supported on bearing shells 14.
  • the operator-side part of the spiked shaft 2, the machine frame 3 in FIG. 1 to the left side, includes a spreading device for winding the hot strip into a collar 6.
  • a support bearing 19 supports the outer left end of the spike shaft second
  • the mandrel shaft 2 is driven by a non-illustrated drive via the drive piece 16, which by means of a coupling, for example a releasable, positive Connection, carried out for example in the form of a toothing 9, is connected to the mandrel shaft 2.
  • a coupling for example a releasable, positive Connection, carried out for example in the form of a toothing 9, is connected to the mandrel shaft 2.
  • the positive connection can also be designed differently, for example, an intermeshing wedge-shaft wedge-hub profile. The torque required for the winding process is thus transmitted essentially via this coupling.
  • connection between the mandrel shaft 2 and the inner ring of the respective bearing 4 is a releasable connection made by means of a tensioning device 5.
  • the tensioning device 5 is constructed such that in a tensioned state, a mandrel shaft 2 introduced into the bearing 4 can be fixed by frictional engagement. For this purpose, a radial expansion in the region of the bearing seat is generated by the tensioning device 5 until it is ensured that there is no slippage between the spine shaft 2 and the inner ring of the bearing 4.
  • the operation of the tensioning device 5 can be effected in different ways.
  • the actuation may e.g. hydraulically or mechanically.
  • FIG. 2 shows an embodiment in which a hydraulic clamping sleeve 17 is arranged on the drive-side end piece 18.
  • the hydraulic clamping sleeve 17 is surrounded by a bushing 11 with a collar, which in turn is enclosed by the inner ring of the bearing 4.
  • the bearing 4 sits on the outer peripheral side on a bearing half shell 14.
  • the two end faces of the bearing 4 are protected by a bearing cover 13 and a seal, not shown.
  • a cavity 12 is provided in the clamping sleeve 17.
  • This cavity has the shape of a hollow cylinder. It extends axially across the width of the bearing 4.
  • the cavity 12 is connected to a channel which leads to the outside and is closed by a closure 15.
  • FIG. 3 shows an embodiment in which the tensioning device 5 is also designed as a hydraulic clamping sleeve 17, but this directly, that is without the interposition of a socket, on the inner ring of Camp 4 acts.
  • the clamping sleeve 17 is fixed by a shaft nut 8.
  • FIG. 4 shows in the upper and lower partial section in each case an embodiment in which the frictional engagement is produced by a conical seat with tapered bushing.
  • the actuation is again hydraulically by now the inner mechanical clamping sleeve 7 is axially offset axially with the outer peripheral side surrounding the cone bushing 11.
  • the clamping is thus generated both mechanically and hydraulically.
  • the clamping or clamping force is generated purely mechanically.
  • a pressure is generated, by means of which the spike shaft 2 can be fixed in the bearing 4 of the machine frame 3, or can be removed by releasing the frictional connection of the machine frame 3.
  • a significant advantage of the invention is that by means of the clamping device quickly and easily a spike shaft 2 can be mounted or removed in a machine frame 3 of a reel 1.
  • the changeover time of a hot strip reel mandrel which often takes six to eight hours of production interruption in known reels, can be significantly reduced.
