Definitions

  • the invention relates to a rolling stand with, mounted in two parallel roller stands and on one side with drive elements that can be coupled with support shaft pairs for roller rings that can be slid onto a seat between the two roll stands, in which the roller stand facing away from the drive elements of the support shafts with the bearings in the direction of the roll axis from the other roller stand can be moved away, and the support shafts consist of two, in the one and in the other roller stand, with the facing end faces that can be placed on the end faces of the rolling ring, can be coupled under axial pressure, and the end faces of the ring pieces extend outwardly inclined surface sections exhibit.
  • the invention has for its object to improve the construction of the rolling stand according to the invention so that the disadvantages and difficulties described above are eliminated.
  • the rolling ring between the two ring pieces is held in a known manner centrally only by the application of axial pressure to the axis of rotation and, after releasing this axial pressure, is held on the ring piece supported by the movable roll stand on the operator side and when the roll stand moves away from the drive side Roller stand transported away
  • the ring pieces 27 and 28 are mounted in bearings 5 and 6 in bearings 5 and 6 in the stationary roll stand 1 and the roll stand 2 detachably connected thereto by plug-in screw elements 3 and 4.
  • the ring piece 27 mounted in the stationary roll stand 1 forms a piece with the drive spindle 16.
  • the two ring pieces 27 and 28 can be clamped against one another in the axial direction by a hydraulic tension nut and released from one another, which consists of a tie rod 17 screwed into the drive spindle 16, an annular cylinder 18, an annular piston 19 inserted therein, an annular nut 20 and an adjusting ring 21 consists.
  • the ring pieces 27 and 28 have on their end faces facing the rolling ring 23 conically outwardly sloping surfaces 27a, 27b or 28a and 28b which can be placed on corresponding counter surfaces on the end faces of the rolling ring 23.
  • the rolling ring is held in the center by the axial tension generated by the hydraulic tension nut 17, 18, 19, 20 in the position shown.
  • the roller stand 2 can be moved in the axial direction with the roller ring 23 resting on a bush 14 seated on the ring piece 28 in the direction of the arrow P from the roller stand 1. Only the bearing 5 with the ring piece 27 and the tie rod 17 of the hydraulic nut screwed into it remain in this stand.
  • the conical surfaces 38a and 38b or 37a and 37b are arranged on intermediate rings 30 and 31. which are placed on ring shoulders 37c and 38c of the ring pieces 37 and 38. These intermediate rings form replaceable wear parts.
  • the ring pieces 47 and 48 have cylinder extensions 47a and 48a which engage with claw coupling elements 50 with axial play.
  • the cylinder extension 48a also serves as a holding element for the roller ring 43 when the roller stand 2 is extended laterally.
