Definitions

  • the invention relates to a roll stand with at least one shifting device for axially shifting the rolls, in particular the work rolls, the rolls being stored and secured in chocks and the chocks in the roll stands being guided in a vertically sliding manner in the direction of the rolling force and thrust blocks leading horizontally in the direction of the roll axis have, on which the stand-supported displacement devices attack from the operator side.
  • a roll stand with two work rolls, two intermediate rolls and two backup rolls and with a device for axial displacement of the intermediate rolls is known.
  • the rolls are mounted in chocks, the chocks being slidably guided in the roll stand in the direction of the rolling force.
  • the intermediate rolls, together with their chocks, can be axially displaced by hydraulic piston-cylinder units acting in the direction of the roll axis.
  • Two axially outwardly projecting arms are provided on one of the chocks of each intermediate roller; on each of these arms the extendable part engages a piston-cylinder unit by means of a connecting member.
  • the two piston-cylinder units are arranged in the roll stand on the side next to the respective chock.
  • the object of the invention is to provide a displacement device for rollers in a roll stand, which allows larger displacement paths for the rolls than before with a compact construction and does not disadvantageously restrict the space on the operator side of the roll stand.
  • the displacement device is connected to the thrust block by means of a gear arrangement which translates the adjustment path of the displacement device, preferably without slippage.
  • This design concept allows the adjustment paths of the displacement device to be reduced several times, while at the same time achieving a large predetermined displacement stroke on the work roll.
  • an extremely compact mechanical construction of the displacement device is possible, so that the space on the operator side of the rolling stand can be used to the extent necessary to date, e.g. for a quick change of the rollers.
  • the thrust block and the chock each have at least one rack arranged opposite one another and that between the racks at least one pinion standing in detail with the racks is arranged, the pinion axis of which is connected to the displacement device.
  • the arrangement of racks and pinions proposed here halves the adjustment path of the displacement device and halves the adjustment forces.
  • an additional locking of the adjusting device or the thrust block is not necessary - except when changing the roller - since the toothing of the rack / pinion / rack is always in engagement.
  • the displacement device is connected to the chock receiving the horizontally displaceable thrust block. This ensures that, seen in the vertical, the displacement device cannot move relative to the thrust piece.
  • Pinions and racks therefore always remain in optimally load-bearing tooth engagement, even if the rollers are worn down to a smaller diameter during operation, the adjustment forces exerted by the adjusting devices are designed by the rack and pinion gear onto the thrust block and thus onto the rollers transfer.
  • the displacement device consists of a double-acting piston-cylinder unit known per se, the reversibly movable piston shaft of which is connected to a thrust sleeve carrying the pinions.
  • the piston is fastened in this way to the displaceable sleeve, which in turn expediently carries a pair of gearwheels on the side, which now meshes on the one hand with the fixed toothed rack attached to the chock and on the other hand meshes with the toothed rack which is located on the thrust piece.
  • the thrust sleeve of the displacement device expediently comprises the piston-cylinder unit in a sliding manner, so that the piston-cylinder unit is at the same time a guide unit for the thrust sleeve, the pinions advantageously being mounted on the outer jacket of the thrust sleeve.
  • the sprockets can flow be mounted so that each pinion sits on a separate journal arranged on the thrust sleeve.
  • the pinions can also be mounted in a bearing block comprising both pinions, which in turn is connected to the thrust sleeve.
  • FIG. 1 shows section A of a roll stand 1 shown schematically in FIG. 4 with a displacement device 2 for displacing the work roll 3.
  • the work roll 3 is mounted radially in the thrust block 4 by means of the bearing 5 and is axially secured.
  • the thrust block 4 is horizontally conductively connected to the chock 6.
  • the sliding guide between the thrust block 4 and the chock 6 is taken over by two sliding rails 7, 8, each on the opposite side of the thrust block 4 or on the chock 6 are attached (Fig. 3).
  • the vertical load and rolling forces are absorbed by the slide rails 7, 8.
  • the chock 6 has a bending block 11 in which e.g. Pressurized bending punches 12 are arranged for balancing and bending the rolls.
  • On the bending block 11 on the vertical contact surface facing the thrust block 4 further sliding or wear slats 13, 14 e.g. arranged from bronze-containing materials.
  • the bending block 11 is extended and carries the displacement device 2, so that the displacement device forms a fixed unit with the chock receiving the horizontally displaceable thrust block 4.
  • the displacement device 2 is connected to the thrust block 4 via a preferably non-slip gear arrangement 15 which translates the adjustment path of the displacement device.
  • the thrust block 4 and the chock 6 with bending block 11 each have a toothed rack 16, 17, and that between the toothed racks two pinions 18, 19 which are in engagement with the toothed racks are arranged, the associated pinion axis 20 of which the displacement device 2 are connected.
  • 1 consists of a double-acting piston-cylinder unit 21 known per se, the piston shaft 22 of which can be reversibly moved as a result of the cylinder spaces 22, 23 acting twice with any pressure medium is and the piston shaft is connected to a thrust sleeve 24.
  • the pinions 18, 19 are overhung on the outer jacket 25 of the thrust sleeve 24.
  • the thrust sleeve 24 comprises the piston-cylinder unit 21 and is secured against rotation by means of a securing bolt 26.
  • a displacement measuring system 27 is arranged on the thrust sleeve.
