Definitions

  • the invention relates to a guide device for the chocks of work rolls of a rolling mill with fixed to the inner sides of the windows of the rolling mill or horizontally arranged guides, wherein the upper and the lower bending block each page are each associated with two mutually parallel guides.
  • Examples of such guiding devices are in DE 39 06 618 C2 or the EP 768 125 B1 disclosed.
  • each bending block In the DE 39 06 618 C2 holding pieces are provided, each holding two pairs of guides, which are guided on these guides the bending blocks for the upper and lower chock.
  • bushes or similar elements are provided, which are provided at the respective ends of the bending blocks.
  • each bending block on a guide bore which is also provided with a provokeslement.
  • the invention has for its object to simplify the guide for the bending blocks and in particular to avoid or substantially reduce the friction occurring in the known systems.
  • a guide device for the chocks of work rolls of a rolling stand with fixed to the inner sides of the window of the rolling stand or horizontally movable guides, wherein the upper and the lower bending block each side are associated with two mutually parallel guides, which thereby is characterized in that each bending block is associated with one of the guides, while it has a recess encompassing this for the parallel guide, wherein 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.
  • the bending system consists of 4 units 1 each with 2 bending blocks 2,3 or 4,5 and a holder 20.
  • two bending cylinders 12 which engage with their rod end 13 at the upper bending block, are seated in the lower bending block.
  • a version with a cylinder is also possible.
  • the rear bracket 20 also serves as a vertical stop for the cylinder movements.
  • the work roll chocks 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 different contour from the previously used design, but the advantages of fast roll change are retained.
  • 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, or similar).
  • FIG. 3 is the holder 20 for the guide rods, in this case 6 and 7, shown enlarged.
  • FIG. 4 Yet another embodiment of the horizontal displacement of the example of the guide rods 6 and 7. This takes place here via wedge surfaces 14 and 15 and a displacement drive 16th
