Definitions

  • the invention relates to a universal roll stand, comprising a multi-part stationary drive-side and a multi-part operator-side, in particular movable, Roll stand, the stand by hydraulically pre-tensioned tie rods or the like are interconnected.
  • Such universal roll stands take parallel to each other in addition to roller sets and horizontal roller axes at the same time roller sets with parallel to each other and vertical roller axes.
  • the mill stands will Usually cast in one piece, mainly because of the roller sets with the vertical roller axes from the side of the vertical stand outside cantilevered lugs must be worn and supported. To do that To be able to simplify manufacturing processes is EP 0 703 016 A2 became known, the roll stand of the universal roll stand in several, easier disassemble individual components to be manufactured and these individual components then screwed together or hydraulically pretensioned using tie rods.
  • the invention has for its object a generic universal rolling stand to make casting and manufacturing technology even easier and cheaper.
  • duo stand frames are, for example, from EP 0 178 462 A1 known, the horizontal forces occurring there being hydraulically preloaded Tie rods are taken over in the operator-side roll stand are pivoted in and out and in the pivoted position in Immerse the stand grooves that are open on both sides.
  • the solution provides for a generic universal roll stand in a simple manner, such stand frames, which, however, are not necessarily those in the Operating position requires vertical tie rods, with the lateral support of the Vertical roller set serving and absorbing the rolling forces to the two Duo stand frame to be provided with screw-on vertical frames.
  • the Stand frames no longer need to cast outward cantilevered lugs to be made, rather in a separate Operation can be made and then only in the form of Vertical frames need to be screwed on to meet the requirements for one To create universal rolling mill.
  • An embodiment of the invention provides that the vertical frames are in several parts and from two arranged at a distance from each other to the stand spars of the roll stands Flange spars and an associated crosshead exist.
  • the two roll stands can be used together connecting, horizontally arranged at the top and bottom, hydraulically preloaded Tie rods immediately to fix the vertical frames on the uprights to use.
  • the crosshead of the operator side Vertical frame up to the crosshead of the drive-side vertical frame extending bolts suggested to the crossheads of the two Vertical frame in one go with the tie rods to the roller stands to connect tensioned flange spars.
  • a universal roll stand 1 shown in FIG. 4 consists of a drive side Roll stand 2 and one - for changing rolls, if necessary, from the stationary one drive-side roller stand 2 movable - operator-side roller stand 3.
  • Both the drive-side and the operator-side roll stands 2 and 3 are based on one shown in Fig. 1, used for a conventional duo-framework Duostaenderrahmen 4. This is in its side opening the window opening 5
  • duo stand frame 4 or the roller stands 2, 3 are used to form the Universal roll stand 1 anchored in FIGS. 2 and 3 vertical frame 9. These are formed in several parts and consist of two flange spars 10, which in the Distance between the stand bars 6a, 6b of the roll stands 2, 3 or duo stand frame 4 arranged from each other and according to FIG. 3 by bridging this distance Crosshead 11 are interconnected.
  • the flange spars 10 are also included Centering bushes 12 are provided, which are in situ (cf. FIG. 4) in a cover position the centering bushings 7 of the uprights 6a, 6b.
  • the Crossheads 11 are in the embodiment with one-piece screw bolts 16th set, for both in the transverse heads 11 and in the flange spars 10 and the stand bars 6a, 6b of the two roll stands 2, 3 or duo stand frames 4 correspondingly aligned bores 17 (see FIG. 3) or 18 (see FIG. 1) are provided.
  • the bolts 16 thus extend over the - starting of the crossheads 11 - entire width of the universal rolling stand 1.
  • the design of the universal roll stand 1 thus enables casting and production technology easy to manufacture because it has essentially smooth surfaces Duo stand frame just as simply designed vertical frame 9 can be anchored.
