Definitions

  • the invention relates to a guide device for four or Multi-roll stands with work rolls, backup rolls and if necessary.
  • intermediate support rolls arranged between the work rolls and the support rolls, where bending blocks for the bearing chocks of Rolling of pairs arranged in the windows of the roll stand are guided on cylinder rods, the two ends of which are direct or are indirectly connected to the roll stand, and between them one each, against the upper and lower bending block of the bearing chocks of a pair of rollers supported bending-piston-cylinder unit is arranged.
  • the invention has for its object the known guide device to improve so that larger support distances are possible.
  • This object is achieved in that the two ends of the cylinder rods not fixed, but axially movable in the Stator windows are mounted, with one of the cylinder bars one Couple in one of the bending blocks and guided firmly connected to the other bending block, and the other cylinder rod firmly connected to one bending block and in the other Bending block are guided longitudinally. With this training the effective support distances of the guide lengths are compared those of comparable known guide devices clearly enlarged.
  • the bearing chocks 5 and 6 are laterally from upper and lower bending blocks 8 and 10, respectively to form a pair.
  • upper and lower holding pieces 14 or 16 arranged, each of which protrude into the window 7 and axial sliding bearings 18 (Fig. 1), into which the cylinder rods 19 of a pair of cylinder rods with their respective ends 19a (Fig. 3) are used in a longitudinally displaceable manner.
  • each bending-piston-cylinder unit 21 Between the cylinder rods 19 of a pair of cylinder rods in the upper and lower bending blocks 8 and 10 are each bending-piston-cylinder units 21 arranged.
  • each slide plates 23 and 24 arranged with which the Device against the action of rotational forces in horizontal planes is secured. These sliding plates 23 and 24 face each other a different structure hardness.
