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 axially displacing 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.
  • a device for axially displacing the work rolls of a roll stand is known.
  • the work rolls are equipped with thrust blocks that can be moved horizontally in blocks that are fixed to the stand.
  • the push blocks the upper work roll and the push blocks of the lower work roll are mechanically connected in such a way that a drive pinion engages in a rack which is arranged on the push block of the upper work roll and engages in a further rack which is arranged on the push block of the lower work roll.
  • the drive pinion is actuated by a power drive. In this way it is possible that both the upper work roll and the lower work roll can be adjusted in opposite directions by the same displacement paths by means of a single power drive. The maximum displacement for the work rolls is not too great, however, even with this known displacement device.
  • a device for the axial displacement of the work rolls consisting of a combination of one or more hydraulic cylinders with a mechanical self-locking adjusting device.
  • the adjusting device contains a self-locking threaded ring, which is connected to the push rod of the hydraulic cylinder via further construction elements.
  • the object of the invention is to provide a displacement device for rollers in a roll stand, which allows larger displacement paths for the rollers 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 and the chock via a gear arrangement which translates the adjustment path of the shifting device and acts without slippage, the thrust block and the chock each having at least one toothed rack arranged opposite one another and at least one with between the toothed racks the toothed rack engaging pinion is arranged, the pinion axis of which is connected to the displacement device.
  • 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 roll stand can be used to the extent necessary up to now, for example for a quick change of the rolls.
  • toothed racks and pinions for example, halves the adjustment path of the displacement device and halves the adjustment forces. Furthermore, an additional locking of the adjusting device or the thrust block is not required - except when changing the roller - since the toothing of the rack / pinion / rack are 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 / pinion gear on the thrust block and thus on 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 rack fixed on the chock and on the other hand meshes with the rack which is located on the thrust piece. If the hydraulic piston and thus the thrust sleeve moves back and forth, then the pair of gears undergoes a rotational movement and at the same time a horizontal relative movement through the thrust sleeve.
  • 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 fly be mounted, with each pinion sitting on a separate bearing pin 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 push block 4.
  • the displacement device 2 is connected to the thrust block 4 via a gear arrangement 15 which translates the adjustment path of the displacement device, preferably without slippage.
  • the displacement device 2 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.
