Definitions

  • the invention relates to a device with a step adjustment for adjusting the Elevation of both sides in chocks, in and up in roller stands Rollers of a roll stand arranged in a lowerable manner on the rolling line, in particular at a four-high skin pass mill operated with low rolling force.
  • roller diameters are used; this mainly affects the work rolls.
  • roller diameters In order not to fluctuate too much with these diameter differences are to align the top edge of the work rolls with the rolling line different measures known, e.g. inserting after each required compensation dimension selected fitting plates, the retraction of in one Selector frames of different heights selectively under the chocks in the stand window of a four-high scaffold or Wedge adjustment devices with one under each chock of the backup roller arranged wedge pair, as known from EP 0 513 946 B1.
  • each upper wedge element by means of a Lift and raise the lifting device together with the respective roller chock is lowerable and the wedge surfaces of both wedges are stepped, the Interlocking steps support the wedge elements vertically.
  • the stair-shaped The grading of the wedge surfaces ensures self-locking of the wedges.
  • the well-known Level adjustments require a lot of effort and make it difficult Roller change.
  • the invention has for its object a device of the aforementioned Art to create a universal with a reduced technical effort Use, i.e. e.g. both in duo as well as quarto or sex scaffolding, in particular Inline four-high skin pass mill, enables a quick change of work rolls allowed.
  • the chocks one of the Rollers on their sides facing the roll stands with a Rack segment are formed and this in the roller stands arranged complementary, away from and towards the rack segments movable toothed rails are opposite.
  • the level adjustment in the form of complementary rack means, of which the rack segments are advantageous are shorter than the toothed rails because they are located in the chocks that are already raised and lowered in the windows of the roller stands According to the invention, therefore, only outside of that for the roll change required expansion space, so that the roll change is unimpeded and quick can be carried out.
  • the roller stands can also be just as simple, in particular smooth, like the interlocking rack means that run in their According to their design, the engagement position also transmits high rolling forces can.
  • the safe engagement after adjustments in the toothing gaps can be achieve this by means of a position measuring system built into the stator cross head the higher-level controller is connected.
  • An embodiment of the invention provides that the toothed rails are cylinder-operated are slidably arranged in vertical slots of the roll stand.
  • the length and Width of the vertical slots corresponds to the dimensions (e.g. approx. 80 mm wide and approx. 650mm high or long) of the total plate-shaped toothed rails.
  • These are with the piston rod of a suitable flange-mounted flange on the outside of the roller stand Cylinder connected.
  • the length of the plate-shaped tooth rails is determined by the roll diameter differences used.
  • the cylinders move the toothed rails backwards or away from the rack segments of the chocks into the disengaged position, and as soon as the toothing of the toothed rails in the vertical slots of the Roller stand is immersed, the roller sets are for the work roller change completely free.
  • the cylinder drives of the toothed rails then only need to be reversed to engage the rack rails with the rack segments.
  • the rack segments are loose in Recesses of the insert side faces formed discs.
  • the certain swiveling or Mobility allows the rack segment to automatically adapt to the Work and / or intermediate rolls specified by means of the bending devices Adjust the bending line or its changes under the rolling force.
  • the disks on both sides of the Rack segments screwed to the chock side surfaces Wear and sliding plates edged. This allows the existing ones to be created Take advantage of wear plates to keep the loose in the recesses to hold the inserted panes securely without losing their mobility restrict.
  • a four-roll or four-high mill stand 1 is one of the two roll stands in Figure 1 partially in the front view shown.
  • the support rolls 4, 5 support the work rolls 7, 8 from above or below.
  • both the upper and the lower work rolls 7, 8 a bending system or a bending device 9, 10 assigned; each of which has, as integrated components, bending cylinders 11 which are suitable for are designed for a positive bend. Nevertheless, it is also a negative one positive and negative bending possible to the nip 12 between the Influencing work rolls 7, 8.
  • the work rolls 7, 8 are assigned bending blocks 13, both on the Operator side as well as on the drive side with movable upper and lower Guide frames 14, 15 are provided.
  • the chock 3 of the upper support roller 4 are cylinders 16 arranged in the bending blocks 13 and the guide frame 14 assigned, which serve to lift or balance the upper support roller 4.
  • the two-sided chocks 3 - in Figure 3 that is drive-side chock shown - the upper support roller 4 on the stator side in each step adjusters 17 assigned to both roller stands.
  • Each consists of one plate-like toothed rail 18, which in a vertical slot 19 of the roll stand 2nd (see Figure 4) is slidably guided; it has the chock 3 on its end facing a toothing profile 20. From the outside to the roller stand 2 - and naturally also in the axial direction or in the plane of the drawing in FIG.
  • Step adjustments 17 are made from complementary rack segments 24 completed, which are formed on disks 25 or disk bodies.
  • the Disks 25 are loose in recesses 26 of the chock side surfaces 27 used and are on both sides of the rack segments 24 of with the Installation pieces screwed wear and sliding plates 28 edged and held in a secure position, but limited rotation (see FIG. 3).
  • Wear or slide plates 29 arranged (see. Figure 2 and 4).
  • the toothed rails are required to align the work roll set with the rolling line 18 by means of the adjusting cylinders 21 only as far as possible in the roll stand 2 to be retracted or withdrawn until their tooth profile 20 no longer protrudes into the stand window - this position is in Figure 2 for the tooth profile shown in dash-dotted lines - and thus out of engagement with the rack segments 24 of the chocks 3.
  • the Chocks 3 of the upper support roller 4 then either raised or lowered until the height of the line is adjusted accordingly. If the toothed rails 18 are then advanced again, they snap with their Toothing profiles 20 in the opposite rack segments 24 of the Chocks 3, as illustrated in Figure 2 with solid lines.
  • Means one in the arranged in the crossheads 30 of the roll stand 2 Position measuring system 31 is ensured via the higher-level control that the Step adjustments 17 of the raised or lowered chocks 3 of the Back-up roller 4 find a safe meshing engagement.
