Definitions

  • the invention relates to a rolling device with at least two at a common Scaffolding arranged on side scaffold beams in vertically along Rolls held on the side girders of movable mounts according to the preamble of claim 1.
  • Such rolling devices can on top and bottom of a roll gap in particular each contain a plurality of mutually supporting rollers, such as a work roll, which comes directly into contact with the rolling stock and in turn on a mostly larger support roll or an intermediate roll, in turn abuts on a support roller rolls.
  • the work rolls and / or the backup rolls and / or the intermediate rollers can axially displaceable against each other be.
  • the height the roll gap should be adjustable, which is a vertical displacement the axial displacement device on the framework requires.
  • the invention is therefore based on the object, a rolling device with at least an axial displacement device, wherein the rolling device, e.g. for rolling thick blocks, or slabs, setting a as large as possible roller tray makes possible.
  • the invention solves this problem by a rolling device with the features of claim 1.
  • Advantage embodiments is based on the dependent Claims 2 to 10 referenced.
  • a generally designated 1 rolling device represented, which is designed as a so-called four-roller framework and two work rolls 2, 3 and two back-up rolls 4, 5. Also one other number of rolls is possible, for example, the formation of a Six-roll stand with additional intermediate rolls between the Work rolls 2, 3 and the back-up rolls 4, 5. Between the work rolls 2, 3 the roll gap 6 is formed for the material to be teased. The height 7 of this Rolling nip 6, the so-called wafer opening, is adjustable.
  • rollers 2, 3, 4, 5 are held in a frame 8, from whose stands the Spars 9 of a stator are shown, each defining a window 10, as a guide for the vertical adjustability of the rollers 2, 3, 4, 5 and Enabling the roll change serves.
  • At least one of the work rolls 2, 3 - usually several of the rolls - is displaceable in the direction of its axial extent.
  • an axial displacement device 11 is provided, which is a drive means, such as a in axial direction of the roller 2, 3 oriented and in extension of these respective Roller lying piston 12 includes and described in more detail below is.
  • the back-up rolls 4, 5 are above backup roll chocks 13, 14 in the edge regions the window 10 held on the spars 9.
  • the support rollers 4, 5 - at least the upper support roller 5 - ensure the back-up chocks 13, 14 are vertically extended Slide rails 29 of lateral holding devices 27, 28, which on the bars 9th are fixed, movable.
  • the slide rails 29 are between the bars 9th and projections of the holding devices 27, 28 are formed and can with be coated with a suitable Reibungsverminderer.
  • the work rolls 2, 3 shown in the embodiment are in the work roll chocks 18, 19 via bearings 26 stored.
  • the work roll chocks (18), 19 are arranged at least in the case of the above the nip 6 Work roll 3 in a U-shaped recess 20 of the upper Support roll chock 14 supported (Fig. 2).
  • Also for the lower work roll 2 may be provided such a solution.
  • This is at least the upper one Work roll 3 with the support roller 5 vertically mitbeweglich.
  • the height adjustment the roll gap 6 is thus simplified. Likewise, the roll change is simplified.
  • the bending device 22 may alternatively but also, as shown in Fig. 2, arranged in recesses 31, 32 of the respective backup roll chock 14 be.
  • This bending device 22 includes as well as the bending device 21 for the lower work roll 2 respectively the bearing ends of a work roll 2, 3rd associated printing elements 23, on the outer edge regions of the work rolls 2, 3 act near their bearings 26 and thus in the edge region the rollers 2, 3 a vertically outwardly from the nip 6 force in accordance with the middle force of the rolling stock, to counteract a bending apart of the work rolls 2, 3 by the rolling stock.
  • the bending device 22 thus acts between the backup roll chock 14 on the one hand and the work roll chock 19 on the other hand, so that a separate support of the bending device 22 to the spars 9 is dispensable.
  • the above-mentioned axial displacement devices 11 are at the outer Edge regions of the work rolls 2, 3 are arranged.
  • the axial displacement devices can be on one side or, for non-driven rollers, on both sides a roller 2, 3 may be provided and include in the embodiment each one arranged horizontally and in extension of the roll axis and the outside of the spars 9 located piston 12th
  • Piston Alternatively, several, horizontal and parallel to the roll axis arranged Piston possible.
  • the piston 12 of the axial displacement device 11 is via an abutment 25 arranged on retaining arms, which in the work roll chocks 18, 19 are arranged horizontally sliding.
  • the holding arms 24 are encompassed by side holding devices 16, 17, which on the spars 9 are fixed and a horizontal movement of the support arms 24 in the direction prevent the roll axis. This is also the piston 12 of the axial displacement device 11 fixed in the axial direction.
  • the holding arms 24 are in the Slide rails 15 of the lateral holding devices 16, 17 in the vertical direction movable.
  • axial displacement device 11 wherein the Cyliner 30 arranged on an abutment 25 on support arms 24 and is fixed by lateral holding devices 16, 17 in the axial direction is possible.
  • the axial displacement device 11 and the bearing 26 of the work roll 2, 3 are thus integrated together in the work roll chocks 18, 19 and together vertically displaceable. A separate vertical adjustment option for an axial displacement device 11 is thus unnecessary.
  • both the back-up chocks 13, 14 as also determines the support arms 24 to the spars 9.
  • the invention is for a variety of numbers and geometric arrangements used by rollers in rolling devices.
