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 guide tracks on rollers directly into or out of the rolling line and in the rolling line while lifting off the guide tracks with the base plates can be braced or moved indirectly by means of short-stroke displacement means from the guide tracks ending at the side of the rolling line into and out of the rolling line and can be locked in the rolling line on the base plates of the rolling stand.
  • 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 guide tracks on rollers directly into or out of the rolling line and in the rolling line while lifting off the guide tracks with the base plates can be braced or moved indirectly by means of short-stroke displacement means from the guide tracks ending at the side of the rolling line into and out of the rolling line and can be locked in the rolling line on the base plates of the rolling stand.
  • 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 a stationary drive which is connected to the rollers in a geared manner and forms the traversing drive along the guideways using 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 torque from the rollers to the guideways and the resulting good contact forces.
  • An arbitrarily long travel path of the roll 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 universal roll stand 1 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 roll stand is supported by gel on axes 11, rollers 10 on a guide track 12, which continues in the area of the rolling line as a base plate 13.
  • a drive motor 14 is arranged in the area of the axis 11, which is force-transmitting via an intermediate gear 15 on the axis 11 and thus on the rollers 10 with the weight of the roll stand 1 and thus the travel drive of the roll stand for extending or retracting in forms the rolling line when changing stands.
  • the drive motor 14 is connected to the electrical power supply via idler cable reels.
  • the rolling stand is moved on the guideways 12 to the side next to the rolling line and then pulled into the rolling line by means of a lifting cylinder 15 onto a wedge-shaped counter surface 16 of the lower, correspondingly designed stand bearing surface, the rollers 10 Lift off the guideway 12. So then the roll stand is clamped to the base plate 13 by means of the clamping cylinders 17 by the clamping pistons 17a inserting themselves into recesses 1a in the clamping strips of the stand foot of the roll stand 1.
  • the direct drive of the roll stand as a travel drive is particularly advantageous, since it saves costly auxiliary equipment and further shortens the changing times for the heavy roll stands.
  • the exemplary embodiment represents a universal stand, but the traversing drive can also be used for heavy duo, trio, four-high and multi-roll mill stands as well as for stand types such as vertical or tilting stands.
