Definitions

  • the invention relates to a rolling stand with a crosswise to the rolling direction through the windows formed by the stand bars of one of the roll stands and into the stand which can be moved in, the set of rolls with the bearing chocks and the rolling bar and the rolling fittings connected to it.
  • roller guides which are placed on the rolling beams and require a relatively large supporting housing.
  • the dimensions of these housings are often so large that, together with the carriage, they cannot be passed through windows in the roller stands that have been expanded to the limits of what is possible.
  • the roller guides and with them as a rule, the rolling beams either had to be dismantled before the roller set was extended, or an exchange stand was used instead of extendable roller sets, i.e. the entire mill stand was exchanged for another.
  • the invention has for its object to improve a roll stand of the generic type so that there is the possibility of the roll set together with the roll chocks, the roll bar and the arranged on this Rolling fittings, eg roller guides with large housings, regardless of their dimensions on the carriage out of the rolling stand and back into this.
  • the two upright sections can be connected to one another in a fixed or detachable manner by cross-beams running above and below the window and, if necessary, the cross-beam curved above the window in a balkane-like manner has a passage recess for the vertical passage of the section of the journal of the rollers underneath.
  • the arrangement can be such that the stand sections above and below the separable stand spar sections and these themselves have the known known longitudinal recesses open in the rolling direction for receiving pivotable and tensionable tie rods articulated in the roll stand.
  • the roller stand section above the separable stand spar sections is expediently firmly connected to the other roll stand by means of a cantilever beam.
  • the adjustment flaps for the axial roller adjustment are, as the invention further provides, articulated on the column sections which can be extended from the roll stand on the carriage.
  • the solution according to the invention allows rolling fittings of practically any width, ie also widths that exceed the width of the stand itself, to be closed without difficulty move out of the roll stand together with the roll bar, roll set and flaps and replace with another roll set with the appropriate fittings.
  • the set of rolls to be exchanged can be completely prepared and set for rolling operation before it is moved into the roll stand. Esp. the rollers can also be axially adjusted with the aid of the adjustment flaps articulated on the column sections before the roller set is moved back into the roll stand.
  • the disassembly or assembly of the roller set located on the carriage outside of the stand can either be done in such a way that the stator sections connected to one another by the crossbeams are removed from the carriage and then the rollers are lifted one after the other or also with stator sticks remaining on the carriage in the way that the rollers are removed vertically upwards, the pin portions of the rollers passing through the passage recess of the balcony-like curvature of the upper crossbeam of the column sections.
  • the roll stand consists of the stand 1 on the drive side and the stand 2 on the operator side 2a, 2b form an independent component which can be separated from the remaining parts of the roll stand by parting lines 4 and 5.
  • the upright beam sections 2a, 2b are connected to one another above and below the rollers 7 and 8 by cross members 9 and 10; they can form a one-piece frame with them or the crossbeams 9 and 10 can be detachably connected to the upright sections 2a, 2b.
  • On the outside of the stator sections 2a, 2b hinged flaps 12 with which the rollers 7 and 8 can be axially displaced.
  • the stand beam sections 2a, 2b are arranged together with the rollers 7 and 8 on the carriage 16, which can be moved here on rollers 15 with rollers 14 and which is at the same time the carrier of the roller beam 17 with the roller guides 18 attached.
  • the carriage with the two stator sections 2a, 2b, the two rollers 7, 8, the roll bar 17 and the roller guide 18 can then be moved out of the roll stand, the width of the roller guide 18 shown in FIG. 2 not offering any obstacle.
  • the roll stand section of the roll stand 2 above the parting line 4, which is firmly connected to the other roll stand 1 by the cantilever cross member 25, remains in the position shown.
  • the carriage 16 shown in FIG. 3, which has been moved out of the roll stand, with the rolls 7, 8, the stand spar sections 2a, 2b, the roll bar 17, the roll guide 18 and the roll chocks 26, 27 and the h olm sections 2a, 2b hinged flaps 12 can be exchanged for another suitably equipped carriage after moving out of the roll stand, which then moves into the roll stand, swivels back the tie rods 22 and braces the section of the stand 2 remaining in the roll stand with the stand spar sections 2a , 2b, makes the roll stand complete and ready for operation again without the need for any special adjustment work, since these have already been carried out beforehand outside the stand on the roll set 7, 8, the adjustment flaps 12 and the roller guide 18.
  • the traverse 9 (see. Fig. 1) has a passageway 9 a to vertically pass through the out been run in from the roll stand set of rollers 7, 8, the shaft portions 7a and 8a upwards.
