Definitions

  • the invention relates to a roll stand, for example a universal roll stand with horizontal and vertical roll sets arranged in a common vertical axis plane, which can be moved either along longitudinal tracks on rollers directly into or out of the rolling line and in the rolling line while lifting off the tracks with the base plates can be braced or moved indirectly by means of short-stroke displacement means from the travels ending at the side of the rolling line into or out of the rolling line and can be locked on the base plates of the rolling stand in the rolling line.
  • a roll stand for example a universal roll stand with horizontal and vertical roll sets arranged in a common vertical axis plane, which can be moved either along longitudinal tracks on rollers directly into or out of the rolling line and in the rolling line while lifting off the tracks with the base plates can be braced or moved indirectly by means of short-stroke displacement means from the travels ending at the side of the rolling line into or out of the rolling line and can be locked on the base plates of the rolling stand in the rolling line.
  • the object of the invention is to be able to move even heavy roll stands very quickly and with the least structural effort over long travels when changing stands.
  • the roll stand has its own drive, which is connected to the rollers in a geared manner and forms the traversing drive along the traversing paths, taking advantage of the weight of the roll stand.
  • the advantage of such an arrangement is that the dead weight of the roll stand is used for the particularly good transmission of the driving force from the rollers to the tracks.
  • An arbitrarily long travel path of the rolling stand can thus be traveled quickly, any auxiliary devices which are spatially obstructing and structurally complex can be dispensed with in an advantageous and cost-saving manner.
  • the device is simple and avoids an additional hindrance to the operating personnel when the rolling stand is moved crosswise.
  • a roll stand 1 and 2 a roll stand 1, for example a universal roll stand, with horizontal rolls 2, 3 and vertical rolls 4, 5 arranged in a common vertical axis plane is shown in principle.
  • the horizontal rollers 2, 3 are adjusted by an adjusting drive 7, while the vertical rollers 4, 5 are adjusted laterally by adjusting drives 8 and 9.
  • the rolling stand 1 is in Figs. 1 and 2 in the operating position, i.e. H. in the position retracted into the rolling line L of a rolling mill, not shown. This is supported with its scaffold feet 1 b on base plates 13 with respect to the foundation.
  • the base plates 13 consist of a U-shaped welded construction with reinforcing ribs, in which pairs of clamping cylinders 17 are fastened on both sides, the clamping pistons 17a of which are inserted into recesses 1 of the clamping strips of the frame feet 1b for bracing the rolling stand 1.
  • Both the underside of the stand feet 1 b and the upper side of the sole plates 13 located on the side of the rollers 10 have wedge-shaped sliding surfaces 16a, 16b which are formed in opposite directions and by means of which the rolling stand 1 is displaced into the rolling line L by means of a displacement cylinder 18 via displacement rods 18a. H. is pulled into the operating position, the rollers 10 lifting off from the upper edge of the soleplate 13, one longitudinal section 13a of which forms the travel path in the region of the rolling line L. Outside the rolling line L transverse to this, the trajectory continues in a rail track 12a, which is aligned with its upper edge with the upper edge of the soleplate 13.
  • shafts 11 are rotatably mounted in the stand feet 1b parallel to the rolling line L, on the pins of which rollers 10 are seated in a rotationally fixed manner.
  • a shaft 11 is connected to a drive motor 14 via an intermediate gear 15.
  • the drive motor 14 with an intermediate gear 15 as a traversing drive is arranged on the scaffold base 1 b.
  • the drive motor 14 is connected through idler rolls of cable to the electrical 'power.
  • the rolling stand 1 located in the rolling line L is extended transversely to the rolling line L from the operating position by first removing the rolling stand 1 with its wedge-shaped sliding surfaces 16a from those on the after releasing the clamping pistons 17a by means of the shift cylinder 18 via the shift linkage 18a Sole plates 13 attached wedge-shaped sliding surfaces 16b is pushed off until the rolling stand 1 with its rollers 10 comes to rest on the track 13a in the area of the sole plates 13 or the adjoining rail track 12a. Then the roll stand 1, from driven the traversing drive 14, moved along the rail track 12a into the finishing plant, while a new rolling stand on the rail track 12a, also driven by a separate traversing drive 14, is moved until the installation position.
  • the new rolling stand is slid along the wedge-shaped sliding surfaces 16b located on the base plates 13 with the wedge-shaped sliding surfaces 16a of the stand feet 1 thereon while the rollers 10 are lifted off the travel path 12a or 13a into the operating position in the rolling line L and the clamping cylinder 17 immovably fixed with respect to the sole plates 13 by means of the clamping piston 17a.
  • the formation of the roll stand with its own travel drive 14 is particularly advantageous in the case of heavy roll stands and longer travel paths for changing stands, since the dead weight of the roll stand is non-positively connected between the rollers 10 and the railroad for transmitting the driving force.
  • the direct drive.b of the roll stand as a travel drive is particularly advantageous because it saves costly auxiliary equipment, and the change times for the heavy roll stands are further increased be shortened.
  • the exemplary embodiment represents a universal stand, but the traversing drive can also be used for heavy duo, trio, four-high and multi-roll rolling stands as well as for stand types such as vertical or tilting stands.
