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 by means of balancing cylinders and mechanical means assigned to a roll change by the chocks to prevent damage to their bales from being touched above the lower work roll, the mechanical means being pivotable Include support levers that are supported in their operative position with their free ends on the opposite chocks.
  • US-A-3 877 276 discloses support levers pivotally connected to one of the chocks of one of the rolls of a pair of rolls, the legs of which can be displaced in a groove of the opposite chocks during operation of the rolls and for changing rolls with one of the groove excavated support on the edge of the groove. Since the support levers are never completely lifted out of their groove, mutual axial displacements of the rollers are prevented in the case of roller sets prepared for removal. However, this has the disadvantage that such axial displacements are not possible even during rolling; Scaffolds common today, however, often have additional setting options in which work rolls must also be axially shifted against each other during rolling operation, e.g.
  • the recesses or grooves would have to be extremely long or wide in order to allow relative axial displacements relative to one another during the rolling operation, and accordingly the rollers have to 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 in a secured middle position with axial displacement so far above the lower one when the roll is changed in generic roll stands that contact with the bale and thus damage to its lateral surfaces are excluded are.
  • 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, or only to a small extent, taken up.
  • 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 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 supporting a roller 20, which allows the work rolls to be extended by means of a liftable extension rail 21.
  • FIG. 2 shows a side view of a chock 8 of the upper work roll 10 which has been broken open in some areas.
  • the pivot pin 15 is mounted with slight play.
  • the support lever 16 Connected to it is the support lever 16 which can be pivoted within the slot 14 of the projection 12.
  • a shaft 23 engages in a form-fitting manner in one of the ends of the pivot pin 15 and is held by a plate which overlaps a collar and is provided with an actuating lever 24 at the free end which bears against a bolt 26 which is arranged on the displaceable block 3 and can be actuated by a bolt cylinder 25.
  • FIG. 3 shows the shaft 27 of the locking cylinder 25, on which a ring shoulder 29 of the bolt 26 is fixed by means of a nut 28.
  • one end 30 of the locking bar 26 engages behind a strip 31 of the chock 8 and thus connects the displaceable block 3 with the chock 8, so that when the upper work roll 10 is axially displaced, the chock 8 of the displaceable block 3 takes along.
  • 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 middle 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.
  • the engagement-side flanks of the groove 19 are chamfered and wedge-like widened and / or the edge strips of the flanks of the support lever 16 lying at the 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 bars 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 the recesses fixed to the stand and thus lock the displaceable blocks 3 in their zero position with the stand, so that their position does not change during the following process of extending and an unlocking can take place after retracting the exchange rate of the work rolls .
  • 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 bias by the spring 17.
  • the upper work roll 10 with chocks 8 is slightly raised by means of the upper bending cylinder 5, and by retracting the locking cylinder, on the one hand, the interlocks between the displaceable blocks 3 and the stand are released, the displaceable blocks 3 simultaneously with the chocks 8 get connected.
  • the support levers 16 are then simultaneously lifted out of the grooves 19 and pivoted back against the force of the springs 17 into their extreme position shown in FIG. 1, so that now after the application of the bending cylinder 5 corresponding to the rolling, the tapping can be done.
  • the invention is not limited to the illustrated embodiment; in particular, the actuation of the support lever 16 can be designed differently.
  • actuating devices provided for it can be arranged, and in the case of double-acting drive devices it is also possible to dispense with pretensioning by means of a spring.
  • 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.
