Definitions

  • the invention relates to a rolling device with at least two rollers arranged on a common stand, held on lateral stand rails in bearings that can be moved vertically along the lateral stand rails, according to the preamble of claim 1.
  • Rolling devices of this type can in particular each contain a plurality of mutually supporting rolls, for example a work roll which comes into direct contact with the rolling stock and in turn rolls on a mostly larger support roll or an intermediate roll which in turn rests on a support roll.
  • the work rolls and / or the backup rolls and / or the intermediate rolls can be axially displaceable relative to one another. If the roll bales are contoured, at least two rolls are thus possible on the rolling stock passing through the roll gap.
  • the height of the roll gap should be adjustable, which requires a vertical displacement of the axial displacement device on the stand.
  • the integration of the axial displacement device into the components receiving the bearings for a work roll has achieved a considerable structural simplification, in which the separate vertical displaceability of the axial displacement device is no longer necessary.
  • the roll change is made easier.
  • the spatial conditions are particularly favorable.
  • FIG. 1 is a perspective view of two side rails of a rolling device according to the invention, each with a pair of work rolls and a backup roll,
  • FIG. 2 shows a sectional view of the device according to the invention according to FIG. 1 approximately along the plane II-II in FIG. 1
  • Fig. 3 is a partially sectioned plan view of the end faces in the
  • a rolling device designated overall by 1 is shown as an example, which is designed as a so-called four-roll stand and comprises two work rolls 2, 3 and two support rolls 4, 5. Another 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 support rolls 4, 5. Between the work rolls 2, 3 is the roll gap 6 for the material to be rolled educated. The height 7 of this roll gap 6, the so-called roll emergence, is adjustable.
  • rollers 2, 3, 4, 5 are held in a stand 8, from the stands of which the spars 9 of a stand are shown, and each of which delimit a window 10 which acts as a guide for the vertical adjustability of the rolls 2, 3, 4, 5 and serves to enable the roll change.
  • At least one of the work rolls 2, 3 - usually several of the rolls - is displaceable in the direction of its axial extension.
  • an axial displacement device 11 is provided, which comprises a drive means, for example a piston 12 oriented in the axial direction of the roller 2, 3 and lying in the extension of this respective roller and which is described in more detail below.
  • the support rollers 4, 5 are held on the spars 9 via support roller chocks 13, 14 in the edge regions of the windows 10.
  • the support roller chocks 13, 14 are movable in vertically extending slide rails 29 by lateral holding devices 27, 28 which are fixed to the bars 9.
  • the slide rails 29 are formed between the bars 9 and projections of the holding devices 27, 28 and can be coated with a suitable friction reducer.
  • the work rolls 2, 3 shown in the exemplary embodiment are mounted in the work roll chocks 18, 19 via bearings 26.
  • the work roll chocks (18), 19 are supported in a U-shaped recess 20 of the upper support roll chock 14, at least in the case of the work roll 3 arranged above the roll gap 6 (FIG. 2).
  • Such a solution can also be provided for the lower work roll 2. So that at least the upper work roll 3 is vertically movable with the backup roll 5. The height adjustment of the roll gap 6 is thus simplified. The roll change is also simplified.
  • the bending device 22 is also arranged vertically within the recess 20.
  • the bending device 22 can alternatively, as shown in FIG. 2, be arranged in recesses 31, 32 of the respective support roller chock 14.
  • the bending device 22 thus acts between the support roller chock 14 on the one hand and the work roll chock 19 on the other hand, so that separate support of the bending device 22 on the bars 9 is unnecessary.
  • the above-mentioned axial displacement devices 11 are arranged on the outer edge regions of the work rolls 2, 3.
  • the axial displacement devices can be provided on one side or, in the case of non-driven rollers, on both sides of a roller 2, 3 and in the exemplary embodiment each comprise a piston 12 which is arranged horizontally and in the extension of the roller axis and is located on the outside of the spars 9. Alternatively, several pistons arranged horizontally and parallel to the roller axis are also possible.
  • the piston 12 of the axial displacement device 11 is arranged via an abutment 25 on holding arms which are arranged to slide horizontally in the work roll chocks 18, 19.
  • the holding arms 24 are encompassed by lateral holding devices 16, 17 which are fixed to the spars 9 and prevent horizontal movement of the holding arms 24 in the direction of the roller axis.
  • the piston 12 of the axial displacement device 11 is thus also fixed in the axial direction.
  • the holding arms 24 are movable in the slide rails 15 of the lateral holding devices 16, 17 in the vertical direction.
  • axial displacement device 11 Another arrangement of the axial displacement device 11, in which the cylinder housing 30 is arranged on the support arms 24 via an abutment 25 and is fixed in the axial direction by means of lateral holding devices 16, 17, is also 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 are vertically displaceable together. A separate vertical setting option for an axial displacement device 11 is therefore unnecessary.
  • a lateral holding device is conceivable on the spars 9, which fixes both the support roller chocks 13, 14 and the holding arms 24 on the spars 9.
  • the invention can be used for a wide variety of numbers and geometrical arrangements of rolls in rolling devices. LIST OF REFERENCE NUMBERS
