Definitions

  • the invention relates to a roll stand with a roll changing device in which the chocks for upper rolls and chocks for lower rolls which can be raised and lowered in the stand window when lowered against a movement in the direction of the roll axes are positively locked one after the other by means of feet on the stand window, which support supports can be removed and together with the rollers can be moved out of the roll stand in the axial direction.
  • Such roll stands are often used as four-high stands in tandem cold rolling mills or single roll stands.
  • the roll change option is limited to the use of similar roll sets.
  • the entire roll stand would have to be converted for other roll sets.
  • the support beams in the form of support beams running through from one to the other stand window with recesses for unobstructed passage of rolling stock.
  • the support beams are attached to the roll stands instead of the known support beams and fulfill the same functions there as these.
  • the lifting and lowering devices for the chocks are installed in the supporting beams as hydraulic lifting cylinders, which in particular serve to bend the rolls. Hose connections do not have to be loosened for a roll change, since the hydraulic connections are firmly piped to the support beams.
  • the support beam lying in front in the rolling direction above and below the recesses be equipped with counter cylinders acting against the rolling direction for the wedge blocks of multi-roller sets that serve to position the lateral intermediate rolls.
  • This arrangement permits the problem-free use of multi-roller sets and at the same time ensures a precise, non-positive and reliable adjustment of their wedge blocks.
  • an embodiment is particularly advantageous in which the positioning cylinders for the lower front Wedge block are in the amount of the relevant driving groove and for the bridging of the distance between the jack cylinders and the wedge block in the driving groove between the chocks a fitting piece which is displaceable and a corresponding fitting piece are arranged in the other driving groove.
  • a fitting piece bridging the distance from this can also be arranged in a suitable groove in front of the positioning cylinders of the upper front wedge block. Since this is not required for the displacement of the chocks when changing the roller, the adapter cannot be displaced in the direction of the roller axis.
  • the arrangement enables the use of short positioning cylinders and results in a good distribution of the positioning force over the wedge blocks.
  • the stand cheek 1 of the roll stand on the right-hand side in the rolling direction and represented by an arrow and the corresponding stand cheek 2 of the left-hand roll stand are connected to one another on the inside of the stand window by a rear support beam 3.
  • a front support beam 4 connects the stand cheeks, not shown on the opposite side of the stand window.
  • the support beams 3 and 4 are provided with driving grooves 5 and 6 for receiving the feet 7 of the upper chocks 8 and the feet 9 of the lower chocks 10, in which, according to FIG. 1, an upper work roll 11 and a lower work roll 12 of a four-high rolling arrangement are mounted are.
  • the support beams 3 and 4 have recesses 13 and 14 for the passage of the rolling stock.
  • the chocks 15 and 16 correspondingly designed in the outer contour serve to support rolls of a multi-roll arrangement, namely the upper and lower work rolls 17 and 18 as well as the upper and lower intermediate rolls 19 and 20.
  • the lateral intermediate rolls 21 and the support rollers 22 are mounted in four wedge blocks 23, of which only the upper front is cut and the lower front is shown in view.
  • the wedge blocks can be pivoted via steering axles 24. They rest on fitting strips 25 on fitting pieces 26 and 27 or on the support beam 3. They are adjusted by adjusting cylinders 28 in the support beam 4.
  • the adapters 26 and 27 are displaceable in the driving grooves 5 and 6 and are pulled out of the roll stand with the chocks 15 and 16 of the multi-roller arrangement.
