Definitions

  • the invention relates to a roll stand with work rolls mounted in chocks, the upper of which can be lifted off from the lower one by means of balancing cylinders and can be supported on the roll by mechanical chocks assigned to avoid contact with their bales above the lower work roll.
  • roller set to be replaced becomes longer due to such additional axial displacements, so that its handling is made more difficult.
  • Scaffolds common today often have additional setting options in which work rolls must also be axially shifted against each other during rolling operation, e.g. to be able to place bale ends of work rolls over the edges of the rolling stock or to be able to change the effective crowning with the help of a special grinding (CVC).
  • CVC special grinding
  • the recesses must be made extremely long so as not to impede the relative axial displacement during operation, and accordingly the rollers must be shifted further against one another in order to change the rollers.
  • the invention is based on the object of providing a simple device by means of which the upper work roll can be supported so far above the lower one when changing rolls in generic roll stands that touching the bales and thus damaging their surfaces are excluded.
  • the device should also be so light and easy to use that additional times for parking the upper work roll on the lower one are not used or only to a minimal extent.
  • FIG. 1 shows a vertical section through a stator 1 shown broken off, which shows a fixed block 2 held by screws in the stator window, in which blocks 3 and 4 which are displaceable parallel to the axes of the rollers are held, each with hydraulic bending cylinders 5 are equipped to bend the work rolls.
  • the piston rods of these bending cylinders 5 engage behind ears 6, 7 of the chocks 8, 9 of the work rolls 10, 11.
  • the chocks 8 of the upper work roll 10 encompass side flanks 13 of the chocks 9 of the lower work roll with shoulders 12.
  • the lugs 12 are each equipped with a slot 14, in which, supported by a pivot pin 15, support levers 16 are pivotally arranged.
  • the support levers 16 are in turn equipped at the rear with a groove in which a spring 17 is held, which in the exemplary embodiment is single ended with the support lever 16 connected leaf spring it formed, the free end of which is supported against a wear plate 18 of the chock 8.
  • the upper end of the chock 9 of the lower work roll 11 is provided with a groove 19 for receiving the support lever 16.
  • the ears 7 of the chock 9 of the lower work roll 11 not only engage under the piston rods of the bending cylinders 5, they are also equipped with a pin 20 supporting a roller, which allows the work rolls to be extended by means of a liftable extension rail 21.
  • the upper chocks 8 are first raised into the position shown by means of the bending cylinders 5, which also serve for balancing, via their ears 6. Since the shifting devices of the work rolls, not shown, have previously shifted them into their axial central or zero position, the springs 17 press the support levers 16, which can be pivoted about pivot bolts 15, into the groove 19 of the chocks 9 of the lower work rolls 11.
  • an area of the shaft of the support lever 16 lies against the flank 33 of the bar 31 of the chock 8 acting as a stop, and when the loading on the bending cylinder 5 decreases, the bottom of the slot 14 lies on a surface 34 of the head of the support lever 16 , so that taking into account the play of the pivot pin 15 in the bushings 22 leading it, the transmission of the load of the upper work roll 10 with chocks 8 takes place over this head surface and the pivot pin 15 is not subjected to any shear forces.
  • the engagement flanks of the groove 19 are beveled and wedge-like widened and / or the edge strips of the flanks of the support lever 16 lying in front in the pivoting direction are tapered in a wedge shape.
  • the actuation lever 24 In order to allow the support levers 16 to engage in the groove 19, their prestressing by the springs 17 is not sufficient, however. It is also necessary for the actuation lever 24 to be released. In the exemplary embodiment, this is achieved by actuating the locking cylinder 25. During the rolling, the piston of the locking cylinder 25 is retracted and the ends 30 of the locking bolts 26 overlap the strips 31 of the mounting pieces 8 connected to the sliding blocks 3. If the work rolls 10 and 11 are moved into their symmetrical middle or zero position, the locking cylinder 25 can be actuated.
  • the lugs 32 of the latch 26 penetrate into stand-fixed recesses and thus lock the displaceable blocks 3 in their zero position with the stand, so that their position does not change during the following extension process and unlocking can take place after the exchange rate of the work rolls has been retracted .
  • the actuating levers 24 of the support levers 16 are also released, so that they can now enter the groove 19 under the action of their prestress by the spring 17.
  • the invention is not limited to the illustrated embodiment; in particular, the actuation of the support lever 16 can be designed differently. Actuators provided specifically for him can thus be arranged, and in the case of double-acting drive devices it is also possible to dispense with pretensioning by means of a spring. There is also the possibility, with appropriate dimensioning, of transmitting the forces absorbed by the support lever via the pivot pin 15, and of course it is possible to make the pivot pin and the shaft controlling it in one piece.
  • the upper work roll is supported for the roll change on the lower one while maintaining a distance with little effort, without requiring a special axial displacement of the work rolls against one another, and at the same time the work rolls are not only held at a predetermined distance, they are also securely fixed one above the other in a symmetrical position.
