Definitions

  • the invention relates to a device for variably adjusting the center of the stand on roll stands.
  • Devices of this type have become known in numerous forms of training. These proposals consistently aim to either raise or lower the height of the support plane of the feed and discharge devices for the rolling stock or the rolling stand itself, i.e. H. in one case to align the center of the rolling stock brought up to the position of the roll gap center of the pair of rolls in the roll stand, or in the other case to center the center of the roll gap of the roll stand on the center of the incoming rolling stock.
  • Vertically swiveling roller table sections are used in front of and behind the roll stand or lifting devices for the roll stands themselves or for support frames of the roll sets which are arranged so as to be vertically displaceable in the stand. Because of the large weights, sliding wedge arrangements of various designs are mostly used as lifting devices.
  • the invention has for its object to avoid these disadvantages and to provide the possibility of a continuous adjustment of the position of the vertical rollers to the height of the position of the webs of the beams to be rolled.
  • the vertical rollers arranged and guided in the side parts can be moved up and down and adjusted independently of the respective position of the horizontal rollers forming the horizontal roll gap; they can therefore be continuously adjusted to the center plane of the web of the rolled beam.
  • the side parts, with sliding surfaces adjacent to the sliding surfaces of the vertical stands can have approaches with vertically extending longitudinal recesses above and below the guides for the bearing chocks for receiving ends of the horizontal tie rods projecting outwards on both sides of the vertical stand.
  • the tie rods can have a hydraulic nut at one end and a locking wedge at their other end.
  • both sides of the vertical stand VS side parts ST are provided, which can be moved up and down in the direction of the double arrow PS with sliding surfaces, not shown, on corresponding sliding surfaces on the vertical stands VS. They are driven and positioned by the tappets of the lifting devices HE that reach under them.
  • the vertical rollers VW are guided in a manner also not shown, and in the vertical stands VS, the horizontal rollers are also shown in a manner not shown HW stored.
  • the two side parts ST are in their lowest position, delimited by the two longitudinal recesses LS, and in the position shown in FIG. 2 in the corresponding highest position.
  • the common horizontal center plane ME of the pair of vertical rolls VW can be steplessly aligned with the position of the center of the web of the beam to be rolled, determined by the two horizontal rolls HW.
