Definitions

  • the invention relates to a bending and balancing device for axially displaceable rolls of a roll stand, in particular for the work rolls of a four-high roll stand, a guide block being arranged on both sides in the window of each roll stand stand and the roll chocks on both sides on an upper or respectively vertically guided guide block the lower lifting housing is supported in a horizontally sliding manner and the roll bending forces are transmitted from bending cylinders to the roll chocks.
  • a bending and balancing device of the type mentioned is known from DE-OS 36 27 690.
  • this bending and balancing device two bending cylinders act on each lifting housing that horizontally guides the roll chocks, which are arranged such that the respective upper lifting housing receives the cylinder piston, while the piston rod is connected to the lower lifting housing.
  • the cylinder pistons arranged in the upper lifting housing are pressurized on the outside of the piston, as a result of which compressive forces are exerted on the piston rods act on the lower lift housing.
  • upward forces are transmitted from the upper lift case to the slide surfaces of the chocks, and downward forces are transmitted from the lower lift case to the slide surfaces of the lower slide.
  • the arrangement of the lifting housing and bending cylinder can be easily replaced for maintenance purposes, which means that shorter downtimes of the roll stand can be achieved; this applies all the more if the hydraulic device for axial work roll displacement is also connected to the lifting housing.
  • the object of the present invention is to improve the known bending and balancing device and to apply pressure forces as separately as possible to each individual lifting housing in order to be able to influence the roll bending even better and to be able to adjust the balancing of the rolls with the chocks even more precisely in order to be able to do so to avoid uncontrolled forces and moments on the heavily loaded roller bearings.
  • At least one preferably hydraulically acting bending cylinder acts on each upper and lower lifting housing and is supported on the guide block fixed to the stand.
  • the bending forces advantageously act on each individual lifting housing and thus separately on the chocks of the upper and lower work rolls. Reactions of the bending forces as a result of reaction forces on the upper and lower work roll are avoided, since the reaction forces are absorbed by the roll stands. As a result, the Bending forces are applied to each individual roller more precisely and more effectively.
  • the guide block has in its central region a web projecting into the stand window of the roll stand, on the upper and lower web surface of which the bending cylinder is supported.
  • a further embodiment of the invention is characterized in that the bending cylinder is arranged at least partially in the lifting housing, the cylinder piston being guided in a corresponding bore in the lifting housing and the piston shaft being connected to the web of the guide block.
  • the lifting housing for supporting the roller chock has an upper shoulder in which the slide for the horizontal contact surface of the roller chock is embedded in such a way that the center of the bending cylinder and the center of the contact surface lie in a vertical plane. This avoids additional frictional forces on the support surfaces, since no moment can occur between the support of the work roll chocks and the bending cylinder.
  • Another embodiment of the invention is concerned with the measure that the guide block has a central projection adapted to the vertical extension of the lifting housing, which engages in a correspondingly designed recess in the central lifting housing and that at least partially on the vertical contact surfaces of the lifting housing to the guide block and the roller chock Sliding surfaces are arranged. This ensures that each lifting housing is guided centrally over the greatest possible length on the guide block, the frictional forces counteracting the displacement being limited to the design-related minimum dimension.
  • a device for axially displacing the rolls, in particular the work rolls is connected to the lifting housing and is connected to the roll chock with the aid of at least one driver element.
  • the work rolls 1, 2 are mounted in chocks 4, 5 in the stand 3 of the roll stand (not shown); the upper work roll 1 in the upper roll chock 4 and the lower work roll 2 in the lower roll chock 5.
  • Each roll chock is slid horizontally on both sides on the shoulder 9 of a lift housing 6, 7.
  • the roller chock is provided with a support surface 8 and a slide 10 is embedded in the load-bearing shoulder 9 of the lifting housing.
  • the lifting housing 6, 7 is guided in a vertically sliding manner on a common guide block 11.
  • the guide block 11 is firmly connected to the roll stand.
  • the guide block has a central projection 12 which is approximately matched to the vertical extent of the lifting housing 6, 7 and which engages in a correspondingly designed recess 13 in the central longitudinal region of the lifting housing.
  • the vertical contact surfaces of the lifting housing with the guide block 11 and the roller chock 4, 5 are provided with the sliding surfaces 14, 15 (FIG. 2).
  • the bending and balancing cylinders 16, 17 are in the
  • Lift housing 6, 7 arranged such that the cylinder piston 18 is guided in a corresponding bore 19 in the lifting housing and that the piston shaft 20 is supported on a web 21 of the guide block 11 which projects into the stator window 28.
  • Fig. 2 shows a partial section of the scaffold stand 3, not shown, with which the guide block 11 is firmly connected.
  • the central projection 12 of the guide block, which engages in the corresponding recess 13 of the upper lifting housing 6, is clearly recognizable.
  • the bores 19 shown in dashed lines for receiving the cylinder pistons 18 of the bending cylinders 16 can be seen in the lifting housing.
  • the vertical contact surfaces of the lifting housing to the guide block 11 and the roller chock 4 contain the sliding surfaces 14, 15.
  • a device 24 for axially displacing the work roller 1 is connected to the lifting housing 6 and is connected to the roller chock 4 by means of a driver element 25.
  • the driver element consists, for example, of two pinions 26 which are mounted on the one hand on the thrust housing 27 of the displacement device and on the other hand mesh with a toothed rack (not shown in more detail) which is arranged on the roller chock 4.
  • the bending cylinders 16, 17 arranged in the lifting housings 6, 7 are pressurized on the outside of the piston with a hydraulic medium, each bending cylinder being supported on the upper web surface 22 and the lower web surface 23 of the guide block 11 fixed to the stand.
  • the pressure forces generated are transferred from the bending cylinder to the lifting housing transferred and passed from there into the roll chocks 4, 5.
  • each lifting housing has its own bending cylinder, which is supported separately on the guide block 11, it is possible to apply exactly predetermined bending forces to each lifting housing and thus into each side of the roll chock or to ensure a balanced balance of the roll chocks, so that predetermined bending forces ensure the desired pretension of the work rolls and, on the other hand, adverse moments on the roll bearings are avoided.
