Definitions

  • the invention relates to a roll stand with bearing shaft pairs mounted in two parallel roll stands and couplable on one side with drive elements for roll rings that can be slid onto a seat between the two roll stands, in which the roll stand facing away from the drive elements of the support shafts with the bearings in the rolling axis direction from the other Roll stand is movable away and on the movable roll stand with the roll rings connectable and detachable holding elements are arranged, which are connected directly or indirectly to the inner ring of the respective bearing and on the outer circumference of which the roll ring can be pushed.
  • Roll stands of this type which are also necessary for larger stand dimensions, such as are required for billet-shaped steel or other rolling mills, allow the roll rings to be exchanged without the need for bracing or disassembly of the entire roll stand.
  • the roller stand facing away from the drive elements of the supporting shafts is moved axially in the direction of the other roller stand for the purpose of changing the rolling rings with the bearings removed from the supporting shaft pair, and the supporting shaft pair can be held and fixed in the other one-sided cantilevered cantilever position will.
  • the holding elements which can be connected and detached to the rolling rings on the movable roller stand are connected to the inner ring of the respective bearing and consist of a sleeve onto which the rolling ring can be pushed.
  • this form of training has the disadvantage that the axial positioning of the bushing and thus of the rolling ring seated on the bushing is difficult and requires a relatively large technical outlay.
  • the invention has for its object to improve the generic design of the rolling mill so that these disadvantages and difficulties are eliminated.
  • the support shaft consists of two ring pieces mounted in the one and in the other roll stand, the facing end faces of which can be placed on the end faces of the rolling ring and coupled with this under axial pressure.
  • spur tooth clutches can be arranged on the end faces in a manner known per se, or they can have shoulders or recesses with conical surfaces. There is also the possibility of arranging the spur tooth couplings or the shoulders and recesses on rings which can be placed on ring shoulders of the ring pieces.
  • the ring piece mounted in the drive-side, stationary roll stand can form one piece with the drive shaft.
  • a bushing which forms the holding element for the rolling ring can be mounted in the roller stand which is movable on the operator side de ring piece can be used, and this can have a retaining nut that can be screwed onto the free end.
  • the ring pieces can also have axial cylinder lugs which can be inserted into the supporting bore of the rolling ring and on the end faces of which claw coupling elements which engage in one another with axial play are arranged.
  • the cylinder shoulder of the ring piece mounted in the movable roll stand can form the holding element for the rolling ring itself.
  • the rolling ring between the two ring pieces is held in a known manner only by applying axial pressure centrally to the axis of rotation and, after releasing this axial pressure, rests on the bush mounted indirectly in the operator-side movable roller stand and is removed from the drive side when this roller stand is moved away Roller stand with removed.
  • the roller ring can then be easily removed from the sleeve holding it and replaced by another roller ring.
  • the ring piece stored in the drive-side stationary roll stand does not require any supporting or fixing devices, as is the case with the generic design.
  • the spacer ring arranged between the ring piston and the ring nut of the hydraulic nut creates the possibility in the event of hydraulic failure to release the tension between the two ring pieces in that the spacer ring is burned on and thus the removal of the rolling ring in the manner described is also made possible in this case.
  • the ring pieces 7 and 8 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 toothed rings of spur tooth couplings 9 and 10 are arranged on the mutually facing end faces of these ring pieces 7 and 8.
  • the counter teeth of these spur tooth clutches 9 and 10 are in rings 11 and 12, which are placed on ring shoulders of the rolling ring 13, which is located between the two ring pieces 7 and 8 and is thereby pushed onto a bush 14, one end of which is in the ring piece 8 is inserted while a holding nut 16 is screwed onto the free end and serves as a holding stop.
  • the ring piece 7 mounted in the stationary roll stand 1 forms a piece with the drive spindle 16.
  • the two ring pieces 7 and 8 can be braced against one another in the axial direction by a hydraulic tension nut and can be released from one another, consisting 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 drive shaft 16 with the ring piece 7, the rolling ring 13 and the ring piece 8 under the clamping pressure of the hydraulic nut 18, 19, 20, 21 form a composite element which acts like a one-piece roller.
  • the roller stand 2 can be moved away from the roller stand 1 in the axial direction with the roller ring 13 resting on the bush 14 in the direction of the arrow P shown. Le remains in this stand diglich the bearing 5 with the ring piece 7 and the tie rod 17 screwed into the hydraulic nut.
  • the ring pieces 27 and 28 have conical surfaces 27a, 27b and 28a and 28b on their end faces facing the rolling ring 23, which can be placed on corresponding counter surfaces on the end faces of the rolling ring 23.
  • the roller ring is held in the center by the axial tension generated by the hydraulic tension nut 17, 18, 19, 20 in the position shown. When this axial tension is released, the removal can be carried out in the same way as explained for the exemplary embodiment according to FIG. 1.
  • 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 roll ring 43 when the roll stand 2 is extended laterally.
  • Fig. 5 shows in the case of the placed on the ring piece 8 ring cylinder 18 with ring piston 19 hydraulic nut that between these ring piston and the ring nut 20 screwed onto the tie rod 17, a spacer ring 51st is used, which can be burned out in the event of hydraulic failure and thus releases the tension between the two elements.
