Definitions

  • the invention relates to a bending and balancing device for axially displaceable work rolls of a four-high rolling mill, in which a stationary block is fixed on both sides in the window of each roll stand, in which bending cylinders are arranged for each of the two work rolls, the force of the hydraulically actuated pistons on the in Axis direction and vertically displaceable work roll chocks is transmitted.
  • Bending devices of this type are e.g. already known from DE-OS 33 31 055, EP-A1 26 903 and EP-A2 67 040.
  • the bending devices between the stator-side blocks and the chocks of the work rolls are arranged so that they are axially displaced together with the work roll chocks in order to ensure a constant force on the chocks in any possible axial position of the work rolls.
  • the object of the invention is to provide a robust, reliable bending and balancing device of the type described in the introduction, with the momentary transfer of the bending and displacement forces to the chocks of the work roll independent of the moment of the work roll.
  • each block is designed on the roller side as a vertical guide, on which a lower lifting housing and an upper lifting housing are guided, the lifting housing has a horizontal wall reaching up to or below the piston rods of the bending cylinders, and a horizontal guide shoulder for each roller side have a sliding surface located in the central region of the assigned chock and, if appropriate, an axial displacement device for the work roll chocks is fastened to the side of each lifting housing.
  • the device according to the invention is particularly suitable for hot plate rolling mills.
  • the lifting housing advantageously enclose the vertical guide.
  • the lower lifting housing has an upper extension part which is guided between the vertical guide and the upper lifting housing.
  • an upper work roll 2 and a lower work roll 3 are mounted in their chocks 4, 5 in the window of a roll stand 1.
  • Each work roll 2, 3 is assigned a support roll 6 or 7, the chocks 8, 9 of which are mounted directly between vertical guide surfaces 10, 11 of the stand window.
  • the chocks 4, 5 of the work rolls 2, 3 are guided between blocks 12, 13 fastened in the stator window.
  • two upper bending cylinders 14 and two lower bending cylinders 15 are arranged in each block 12, 13, piston rods 16 of the upper bending cylinders 14 on the top and piston rods 17 of the lower bending cylinders 15 on the underside of the blocks 12 or extend 13.
  • the blocks 12, 13 are provided on the roll side with a T-shaped vertical guide 18 on which a lower lifting housing 19 and an upper lifting housing 20 are guided.
  • the lifting housings 19, 20 grip around the T-shaped cross section of the vertical guide 18 in a claw-like manner, so that all-round support is ensured in the horizontal plane.
  • the lower lifting housing 19 is provided with a lower guide shoulder 21, against which a sliding surface 22 located on the chock 5 comes to rest.
  • a horizontal wall 23 is arranged, which extends over the piston rods 17 of the bending cylinder 15.
  • the lower lifting housing 19 has an upper extension part 24 which is guided between the front surface 25 of the vertical guide and the opposite inner surface 26 of the upper lifting housing 20.
  • the upper lifting housing 20 has an upper wall 29 which extends beyond the extension area of the piston rods 16 of the bending cylinders 14.
  • the work rolls 2, 3 are assigned axial displacement devices, the construction of which is described below with reference to FIG. 3.
  • a hydraulic cylinder 30 is attached to the lifting housing 19, 20 with a base plate 31.
  • the piston rod 32 of the hydraulic cylinder 30 is connected to a driver housing 33 which is displaceably guided on the hydraulic cylinder 30 and on which a locking hook 34 is rotatably mounted, which engages over a driver bracket 35 arranged on the chock 4, 5.
  • one chock 4, 5 is assigned two axial displacement devices, the hydraulic cylinders 30 of which are jointly acted upon for axial displacement, the force being transmitted from the chock 4, 5 via its bearing 36 to the work roll 2, 3.
  • the bending cylinders 14, 15 arranged in the blocks 12, 13 are acted upon on the outside of the piston, as a result of which forces are exerted by the piston rods 16, 17 on the walls 23, 29 of the lifting housing 19, 20 and by these via the guide surfaces 21, 27 and Sliding surfaces 22, 28 are transferred from both sides to the chocks 4, 5.
  • the tilting moments occurring on all sides of the lifting housings 19, 20 on the blocks 12, 13 are absorbed by the side surfaces of the vertical guide 18 in the event of an eccentric power transmission between the guide shoulder 21, 27 and the sliding surface 22, 28.
