Definitions

  • the invention relates to a roll stand with support and / or work rolls for rolling of sheets and strips in which the upper and lower work rolls may together with the support rollers assigned to them by pairs in opposite directions horizontal displacement of each roller stored within the stand window Chocks can be moved into positions from the common vertical plane are in which by the roll axes of the work and backup rolls crossing vertical planes.
  • European patent application 0 525 552 A1 suggests the chocks of the work and backup rolls common sliding blocks before, which are arranged between the chocks and the roll stand and have on their sides facing away from the chocks wedge surfaces which with vertically adjustable slide drives with the same wedge surfaces correspond. When adjusting these sliding drives, the on wedge surfaces sliding on each other a horizontal displacement of the Sliding blocks, which adjust the side chocks and the rollers are crossed in pairs.
  • actuators have become known from the same document, such as Hydraulic cylinders or spindles acting mechanically on the chocks, with which each have the chocks for changing the roller positions within the Stand window can be moved horizontally.
  • the object of the present invention is to provide a roll stand simple sliding drives and high system stability to create that with simple constructive means an entanglement of the rollers with conventional Storage allows.
  • the invention is also applicable when a so-called duo rolling mill with only two Work rolls is used.
  • the invention provides that each work roll with its roll chocks in one of two is horizontal in the cassettes on both sides of the stand of the roll stand recorded and guided vertically and / or horizontally adjustable therein that the Cassettes can be pivoted in opposite directions about a common central vertical axis are provided by the upper and on the cross member and the cassette lower centering pin bearings is formed and that each cassette is in the area the stand window over gimbaled gimbal supports at both ends supported vertically against the rolling stand frame.
  • each back-up roller with its roller chocks in one of two horizontally into the double-sided stand window of the roller stand extending cassettes and recorded vertically and / or horizontally is adjustable that the cassettes in opposite directions to a common central vertical axis are pivotable, which are on the column cross member and on the Cassette provided upper and lower centering pin bearings is formed and that each cassette in the area of the stand window over at both ends gimbal-supported pendulum supports supported vertically against the rolling mill frame.
  • the pivoting of the cassettes with the respective rollers accommodated therein or pairs of rollers can be according to an embodiment of the invention by means of essentially horizontally acting power drives, on the one hand grasp the roller stand and the other hand on the respective cassette.
  • Mechanical synchronization means prevent the cassette from tilting in the Roller stand.
  • the cassettes can advantageously between both sides arranged hydraulic cylinders can be clamped so that a backlash-free Cassette guidance is guaranteed.
  • the Cassettes can be hydraulically balanced against the upper and lower pendulum supports are.
  • the lower balance also serves to raise the system to change the roller and to move the step wedges to adjust the Allow pass-line.
  • the Hydraulic cylinder for vertical adjustment in the upper or lower cassette adjustable pair of rollers together with the corresponding ones Servo valves as well as the balancing and bending cylinders for the rollers are installed inside the cassette. It is achieved on the one hand that the Rolling forces are always introduced centrally and on the other hand the installation and removal the rollers are significantly simplified.
  • the cassette solution according to the invention allows the work rolls to be moved in the axial direction as well as a positive and negative work roll bending.
  • the axial displacement of the work rolls can be easily achieved if, according to a further feature of the invention, each work roll is displaceable in the axial direction via a two-armed lever system, the pivot point of which is arranged on the cassette, one lever arm of which is connected to a power drive supported on the cassette and the other Lever arm is non-positively or positively connected to the chock of the work roll.
  • connection of the lever arm to the chock takes place via rollers which are arranged at the end of the lever and are supported on the chock.
  • the lever arms in Area of the chocks transverse to the direction of movement of the work rolls are pivotable away to enable the work rolls to be removed.
  • the system according to the invention thus created enables the positive and negative Bending as well as the axial displaceability of the work rolls in a simple functional device with a very large adjustment range for the profile and Flatness control. Dynamic pair crossing is possible with simple means, without having to use expensive, expensive swivel or eccentric bearings.
  • 1 is the stand of a four-high rolling mill, whose Work rolls 2a, 2b and backup rolls 3a, 3b in pairs 2a, 3a and 2b, 3b in an upper cassette 4a or a lower cassette 4b, vertically displaceable led, arranged.
  • the work rolls 2a, 2b are also by means of double-sided lever 5 axially, i.e. can be moved across the drawing plane.
  • the cassettes 4a, 4b extend transversely to the roller pairs, in part partially Rolling plane from one side of the stand 1 to the other and extend into the two sides of the stand 1 provided stand window 6. Between the cheek 6a each Stand window 6 and the cassettes 4a, 4b is left a distance that one allows lateral adjustment of the cassettes 4a, 4b.
  • the roll stand is shown rotated by 90 °.
  • recesses 7 are provided in which the pendulum supports 8 extend approximately vertically.
  • the pendulum supports are on gimbaled at their ends.
  • dome-shaped support pairs 9 provided an inclined position of the pendulum supports 8 even under rolling load enable.
  • the upper and lower pendulum supports 8 are attached to the cassettes 4a, 4b attacking balancing cylinder 12 between the stand head 1b and the Cassette 4a clamped; the pass-line setting (height adjustment of the system) of the lower pair of rollers is done conventionally via step wedges 15.
  • the pass-line setting (height adjustment of the system) of the lower pair of rollers is done conventionally via step wedges 15.
  • the upper, vertically adjustable pair of rollers are hydraulic cylinders 16 together with the associated servo valves in the upper cassette 4a built inside the same.
  • Each work roll 2a, 2b is in the axial direction via a two-armed lever system 5 displaceable, the pivot point 19 on the respective cassette 4a or 4b is arranged, one lever arm at 18a with one on the cassette 4a or 4b supported power drive 20 is connected and the other lever arm 18b is non-positively or positively connected to the chock of the work roll.
  • the connection of the lever arm 18b with the chock 21 takes place via rollers 22, which are arranged at the end of the lever 5 and mounted on the respective Support chock 21.
  • each lever arm as indicated by dashed lines at 23, in the region of an articulated joint 24 transverse to Chock 21 are pivoted to the roller 22 from the area of To move the chock out.
  • a hydraulic cylinder 25 is between the Lever arms of the lever system 5 arranged on both sides of the chocks arranged.
