Definitions

  • the invention relates to a Fuhrungsvor ⁇ chtung for the chock of work rolls of a rolling mill with fixed to the insides of the windows of the rolling mill or horizontally arranged guides, wherein the upper and the lower bending block each side are associated with two mutually parallel guides
  • the invention has for its object to simplify the leadership for the bending block and in particular to avoid or substantially reduce the friction occurring in the known systems
  • this object is achieved with a guiding device for the fitting pieces of work rolls of a rolling mill with guides fixed or horizontally movable on the insides of the windows of the rolling mill frame, with two guides arranged parallel to one another being assigned to each of the upper and lower bending blocks is characterized in that each bending block is associated with one of the guides, while it has a recess encompassing this for the parallel leadership, the upper Bending block is guided on one of the parallel guides and the lower bending block on the other guide.
  • each bending block has only one tube, which receives two slide bushings, so that this guide performs the actual leadership task.
  • a recess is then provided in this bending block.
  • associated other bending block serves this guide, for which a recess is provided in the aforementioned bending block, as the actual guide, while there is provided for the other guide a recess.
  • Bushings can be provided as plain bearings in the bending block.
  • anti-rotation sliding plates are provided on the front of the back bracket.
  • the guides can be designed as circular guides.
  • the guides are fastened by means of a holder in turn on the rolling stand.
  • the guide device can be provided with a horizontal displacement system.
  • 1 is a perspective view of the four bending blocks
  • 2 is a side view, partially in section
  • the bending system consists of 4 units 1 each with 2 bending bells 2,3 or 4,5 and a holder 20
  • Based on the one bending block 2 is then provided for the other leadership 6, a recess 10
  • the lower bending block 3 of this page then surrounds the guide 7 with a corresponding recess partially corresponding applies to the bending block of the other side
  • the work roll mounting pieces were designed in their contour so that the line of action of the bending cylinder is as close to the center of the bearing. This results in a design deviating from the previously used contour, but the advantages of rapid roll change are maintained
  • the bending system can be used in conventional design, as well as in connection with means for horizontal displacement (HS) of the work rolls. In both cases, the system can be combined with axial displacement devices (CVC, EDC, oa) -
  • FIG. 4 also shows an exemplary embodiment of the horizontal displacement using the example of the guide rods 6 and 7. This takes place here via wedge surfaces 14 and 15 and a displacement drive 16.
