Definitions

  • the invention relates to an adjusting device for the axially parallel displacement of rolls, in particular work rolls, of a roll stand with the chocks of the rolls, optionally via interposed guide pieces within the stand window, supporting pressure plates which can be displaced on both sides.
  • Such adjustment devices are required in particular if, for example by setting work rolls, the profile of the roll gap of a stand is to be changed, or if, for example in accordance with "Production of Cold-Rolled Strip", Part 1, Verlag Stahleisen mbH, Düsseldorf, 1970, Pages 309 and 310, an additional support of work rolls of small diameter by horizontal displacement against the plane having the axes of the backup rolls to be effected.
  • Such adjusting devices have to meet a number of requirements: the structure should be compact and compact, in order to facilitate the placement in the stand window of a rolling mill, and there should be the possibility of covering exactly definable travel distances with simple means, with adjusting devices being independent or also are to be operated in the same direction or in opposite directions. Furthermore, purely translatory movements are to be carried out in order to offer the chocks of rollers to be shifted exactly aligned contact surfaces.
  • gear boxes were used which react to a rotating positioning movement which, by means of screw spindles encompassed by nuts, bring about the feed movement.
  • gears require an unpleasantly large installation depth, so that it is not possible to accommodate them within the cylinder blocks usually provided in stator windows, but rather it was necessary to use the cylinders for bending and balancing processes in separate cylinder blocks - And to be arranged below the gear boxes.
  • Attempts to reduce the overall height of the gearboxes fail due to the requirement of sufficiently loadable modules and thus sufficiently large gear wheels or threaded spindles.
  • the subdivision of the cylinder blocks also has a disadvantageous effect in that the guide lengths for chocks or pressure pieces which in turn guide them are undesirably restricted.
  • the invention is therefore based on the object of creating a compact adjusting device of the type specified, the actuating stroke of which is easy to monitor or to determine and to specify, which executes predetermined actuating paths largely rigidly without elastic compliance, which is capable of being practically purely translational Perform positioning movements, and which can also be accommodated in conventional, undivided cylinder blocks.
  • the pressure plates are held by wedge adjustment devices, which are arranged in undivided cylinder blocks provided on the window-side flanks of the uprights.
  • wedge adjustment devices which are arranged in undivided cylinder blocks provided on the window-side flanks of the uprights.
  • Only one cylinder block is required per window side of a stand, which is much easier to assemble than two separate blocks, and which in any case has a sufficient guide length for Provides.
  • the adjusting device itself can be made relatively flat and compact, and the actuator can also be provided on the side in such a way that an unfavorably large additional effort is avoided.
  • Fig. 1 the central portions of the uprights 1 are one Stand shown that enclose a stand window between them.
  • cylinder blocks 2 are connected on both sides to the stator bars, which are provided with recesses undercut by wear plates 3.
  • the tongues 4 of a wedge slide are provided horizontally displaceably above the wear plates 3, the inwardly facing surfaces of which are inclined horizontally by 4 ° in the exemplary embodiment relative to the vertical.
  • the base surfaces of the four pressure rams 5, which are guided against the tongues 4, have the same inclination, the base surfaces of which are arranged opposite one another and together support a pressure plate 6.
  • the cylinder blocks 2 each have a pressure medium cylinder 7, by means of which the pressure plate 6 is braced outwards and in the direction of the wear plates, so that the pressure plate 6 is supported by the pressure ram 5, the tongues 4 of the wedge slide and the wear plates 3 on the upright .
  • each guide pieces 8 and 9 are vertically displaceable, which in turn hold the chocks 10 and 11 of the work rolls 12 and 13 with a horizontal guide.
  • the chocks 10 and 11 can be braced against one another by means of hydraulic cylinders 14 and the work rolls can thus be balanced.
  • Further hydraulic cylinders 15 and 16 are each provided in the cylinder blocks 2 and are able to clamp the guide pieces of the intermediate rolls or the chocks of the backup rolls.
  • Fig. 2 shows a parallel to the roller axis vertical section through one of the cylinder blocks 2 at the level of the separating surface between the tongues 4 of the wedge slide 17 and the axis of the hydraulic cylinder 16.
  • the four plungers 5 are shown, to which the pressure medium cylinder 7 is symmetrical or at the intersection of the Diagonals is arranged.
  • the two Tongues 4 of the wedge slide 17 unite and have integrally formed tabs 18 on the right end, which comprise a piston rod head 20 on both sides and are connected to this by bolts 19 penetrating through holes in the tabs 18 and the piston rod head 20.
  • a laterally projecting structure 21 is connected to the upright 1, in which a hydraulic actuating cylinder 22 is pivotably provided.
  • the expediently double-acting hydraulic cylinders 22 are acted upon by a control or regulating device in such a way that the associated wedge 17 is displaced with its tongues. In this case, when it penetrates deeper, it pushes back the plungers resting on it, which in turn push the associated pressure plate further against the force of the pressure medium cylinder.
  • the arrangement is expediently assigned a control and regulating device.
  • the opposing wedge adjustment devices of a stand can be adjusted so that the guide pieces 8 and 9 and the chocks 10 and 11 enclosed by them have their optimal play.
  • the work rolls are shifted by moving the opposing wedges in opposite directions. For example, in Fig. 3, a shift of the work rolls from the plane of symmetry by to reach to the left by the double arrow 23, as shown in the figure, in the stand shown below the wedge slide shown on the left is pulled down and the opposite one in the same frame is pushed upwards. This moves both printing plates to the left by the same amount, and the game once set is retained.
  • the wedge shown on the left is moved upwards and the one shown on the right is moved downwards, in order to achieve the same displacement of the chocks to the left here as well.
  • these shifts are specified and regulated by control devices.
  • the actuating cylinders 22 or their piston rods and / or the wedge slides are equipped with sensors which prescribe their respective position of the control device.
  • One of the actuating cylinders can then be acted upon in a controlled manner, while the others follow the corresponding movements in a controlled manner.
  • an adjustment device is thus created with a low overall height, which gives sufficient space in the stator window for accommodating the cylinder block including its cylinders.
  • the desired adjustability can be obtained even with a tolerable advance of the wedge slide.
  • the control devices in such a way that predetermined inclined positions of a work roll are maintained during the feed.
  • the desired adjustability of the work rolls is achieved without subdivision of the cylinder blocks, and the horizontal forces applied by the work rolls are introduced directly into the uprights.
  • the adjusting device designed according to the invention is shown in a six-roll stand.
  • the invention can also be applied to rolls of any other stands, for example five-roll, four-roll, three or two-roll stands. It can also be varied further.
  • wedge tongues are provided, each with continuous wedge surfaces, the associated, one behind the other, pressure plunger accordingly having different lengths depending on the inclination and their spacing.
  • modified numbers and / or arrangements of the printing stamps can also be selected, and with corresponding spacings of printing stamps arranged one behind the other, there is also the possibility of providing printing stamps of the same length and of dissolving the wedge surface in the partial wedges assigned to the printing stamps arranged one behind the other.
