Definitions

  • the invention relates to a universal roll stand, comprising a multi-part stationary drive side and a multi-part operator side, in particular retractable roll stand, the stand being hydraulically preloaded 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 simultaneously with roller sets parallel to each other and vertical roller axes.
  • the mill stands are usually cast in one piece, mainly because the Roller sets with the vertical roller axes from the side of the vertical stand outwardly projecting support lugs are carried and supported have to.
  • the roll stands of the universal roll stand disassembled into several, easier to manufacture individual components and these Then screw the individual components together or using tie rods preload hydraulically.
  • EP 0 556 631 A is a special construction of a universal roll stand become known, namely that both arranged without assembly Has horizontal and vertical rollers.
  • the vertical rollers are horizontal lateral guide frame arranged for this purpose recordings for the Have cassettes carrying vertical rollers.
  • the invention has for its object a generic roll stand to make casting and production technology even easier and cheaper.
  • duo stand frames are for example from the EP 0 178 462 A1
  • the horizontal forces occurring there hydraulically preloaded tie rods are taken over in the operator-side Roller stands are arranged in and swung out and in the Immerse the swiveled-in position in the upright slots that are open on both sides.
  • the solution according to the invention provides for a generic roll stand of the generic type in a simple way, such stand frames, but not necessarily requires the vertical tie rod in the operating position with which lateral support of the vertical roller set and the rolling forces vertical frame that can be screwed onto the two duo stand frames to provide.
  • the stand frames no longer need casting technology complex, outwardly projecting support lugs to be manufactured, which can rather be manufactured in a separate operation and afterwards only need to be screwed on in the form of the vertical frame to create the conditions for a universal scaffold.
  • the invention also provides that the vertical frame consists of several parts and are arranged at a distance from each other of the uprights of the roll stands Flange spars and an associated crosshead exist.
  • the two roll stands can be used together connecting, horizontally arranged above and below, hydraulically preloaded Tie rod immediately to fix the vertical frame 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 frames 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-frame Duo stand frame 4. This is in its laterally delimiting the window opening 5
  • duo stand frame 4 or the roll stands 2, 3 are 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.
  • crossheads 11 have one-piece screw bolts 16 fixed for both in the crossheads 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 allows casting and manufacturing technology easy to manufacture because it has essentially smooth surfaces Duo stand frame just as simply designed vertical frame 9 can be anchored.
