Definitions

  • the invention relates to a universal stand with adjustable horizontal and vertical roller sets guided in window recesses of the roll stands, in particular in the form of a universal roll stand with two roll stand halves connected by cross members, each formed from a pair of stand spars with crossbeams, in which the bearing chocks of the horizontal roll set between the uprights of the respective uprights and the bearing chocks of the vertical roller set can be moved vertically or horizontally between outwardly projecting lugs of these uprights and the upper ones lifting or lifting the crossbars connecting the uprights. can be swung out horizontally.
  • the expansion of the roller sets and also the installation of the new roller sets therefore require considerable assembly and time expenditure with the resulting long downtimes of the entire rolling mill in which the universal roll stand is located.
  • the invention has for its object to simplify the installation and removal of the roller sets and thus reduce the time required and the assembly effort.
  • a frame cage which has plate-shaped boundary walls and can be connected to lifting devices and which can be moved vertically and, if necessary, horizontally in the roll stand with the outer surfaces of the boundary walls on mutually facing guide surfaces of the uprights of the uprights and can be moved into and out of the latter, and in which the inner surfaces of the boundary walls form guide surfaces for positioning movements of the bearing chocks of one or more of the rollers, the bearing chocks being supported by the frame cage and / or being able to be coupled to one another.
  • all roller sets with their bearing chocks can be brought in or out of the roll stand together when the frame cage is inserted or removed.
  • bearing chocks which are not guided on the guide surfaces of the boundary walls of the frame cage can be guided by rollers on guide surfaces of the uprights.
  • a particularly advantageous embodiment according to the invention consists in the fact that the bearing chocks of the upper roller of the horizontal roller set are guided vertically in the boundary walls of the frame cage, the bearing chocks of the vertical roller set with these boundary walls, and the bearing chocks of the lower horizontal roller with the bearing chocks of the vertical roller set, whereby the bearing chocks can be coupled of the vertical roller set and the lower horizontal roller are guided horizontally or vertically on the guide surfaces of the uprights.
  • the guiding surfaces of the uprights which guide the boundary walls of the frame cage and the bearing chocks of the vertical roller set are expediently in one plane according to the invention and, with the formation of inward-facing heels, form smaller spacings for the bearing chocks of the horizontal roller in guide surfaces, these heels slideways for the horizontal movement of the Show bearing chocks of the vertical rollers.
  • the frame cage can be placed with outwardly projecting lugs on support surfaces arranged on the roll stand halves and can be locked to the roll stand halves by means of adjustment bolts which can be inserted into fixing bores.
  • a particularly advantageous embodiment results when the bearing chocks of the upper and, if applicable, the lower roller of the horizontal roller set are guided vertically in the boundary walls of the frame cage and the bearing chocks of the vertical roller set are guided and held horizontally in this, since this means that not only all the roller sets during installation and Spreading process indirectly on the guide surface Chen the stand spars are guided, but if necessary.
  • the appropriate structural design a lateral insertion and removal of the frame cage with the roller sets is possible.
  • coupling devices that can be coupled, displaceable and fixed lifting devices are arranged on the stand spars of both roll stand halves with this frame cage, then the rolls of the vertical roll set can also be positioned vertically changed, with the result that, for example, after changing the roll set whose setting on the rolling line does not have to be adjusted in height for the entire universal stand, and that position adjustments of the vertical rolls between the individual roll passes can also be carried out in order to achieve greater web center accuracy, so that the rolling stock enters the roll gap in the most horizontal position possible in order to achieve this goal.
  • This has the further advantage that the so-called rocking roller tables previously arranged in front of and behind the universal roll stand can be dispensed with.
  • the universal stand can also be designed according to the invention so that the bearing chocks only the upper roller of the horizontal roll set in the boundary walls of the frame cage are guided vertically and the bearing chocks of the vertical roll set are guided horizontally in this and that the bearing chocks of the lower horizontal roller are coupled with the bearing chocks of the vertical roll set the guide surfaces of the uprights are guided.
  • the frame cage is first brought into the desired position and fixed and then the rollers of the horizontal roller set are centered on the set new rolling line with the aid of the adjusting devices.
  • the uprights 1 of the scaffold are penetrated by four tie rods 2 mounted therein, each of which can be driven in rotation by means of a power-operated worm 3 which engages in a worm wheel 4 provided on the tie rod 2.
  • the tie rods 2 pass into threaded spindles 5, which engage in pressure nuts 6, the recesses of an upper and a lower Crossbar 7, 8 are provided. While the lower pressure nuts 6 are inserted directly into the lower crossmember 8, the upper pressure nuts 6 are each arranged in coupling bushes 9 which, like the lower pressure nuts, are supported on the uprights 1.
  • the upper cross members 7 are pivotally arranged, not shown in the drawing, coupling bushes, while in the opposite end of the upper cross members 7 recesses 7a are provided, which engage with a step of the coupling bushes 9 with corresponding steps, but on the other hand end freely so that the upper cross members 7 pivotable by approximately 90 ° with one swivel release the space formed over the housing windows 10 formed by the column bars 1.
  • the housing window 10 have lower flanks 11, the inside width of which is adapted to the width of the bearing chocks 13 of the lower horizontal roller 14.
  • the flanks 12 of the housing window 10 adjoining shoulders have an enlarged clear width, which enables direct guidance of the bearing chocks 15 of the vertical rollers 16.
  • the bearing chocks 17 of the upper horizontal roller 18 are provided; they are guided vertically between boundary walls 22, which are jointly connected by means of a yoke 21 to the frame cage 19, which can be raised or lowered by means of a lifting eye 20 by a lifting device which is cast onto the yoke 21 connecting the boundary walls 22.
  • the yoke 21 or the boundary walls 22 are connected to a lateral adjustment bar 23, which limits and positions the introduction of the boundary walls 22 into the housing window 10.
  • its yoke 21 and / or the boundary walls 22 are provided with fixing bores 24 (cf. FIG. 2), into which the stator leg (not shown) men 1 guided fixing bolts can be inserted.
  • the boundary walls 22 are thus supported on the one hand against the flanks 12 of the housing window 10 and, on the other hand, with their inner surfaces, expediently secured against axial displacements, they guide the bearing chocks 17 of the upper horizontal rollers 18 in the vertical direction.
  • the boundary walls 22 are each provided with support grooves 25 in the lower region of their inner surfaces, into which horizontally projecting supporting springs 26 engage, which are attached to the top of the bearing chocks 15 of the vertical rollers 16.
  • undercut retaining grooves 27 are provided on the underside of the bearing chocks 15 of these vertical rollers 16, into which the angled ends of lifting eyes 29 can be hung.
  • These lifting eyes 29 in turn encompass (see FIG. 2) lugs 30 of the bearing chocks 13 of the lower horizontal roller 14.
  • the side legs 29a of the lifting lugs 29 are overlapped here (see FIG.
  • the frame cage 19 can then be lifted out of the upright 1 by a simple lifting operation in the vertical direction by means of a lifting device engaging the lifting eye 29.
  • the bearing chocks 17 of the upper horizontal roller 18 lie on the bearing chocks 15 of the vertical roller 16 and both are supported by the support springs 26 of the chocks 15 of the vertical rollers 16 which engage in the support grooves 25 of the boundary walls 22 dug out.
  • a setting frame 31 (FIGS. 3 and 4) is provided on which both roller sets can be placed.
  • the individual bearing chocks 13, 15, 17 are set down on adjustable support surfaces; adjustable support plates 32 are provided here for the bearing chocks 13 of the lower horizontal roller 14, the bearing chocks 15 are received by support plates 13 arranged on both sides and the boundary walls 22 and / or the bearings chocks 17 of the upper horizontal roller 18 are received by support plates 34. It is also possible to provide separate support plates for the boundary walls 22 and the bearing chocks 17.
  • the separate adjusting bar 23 can be dispensed with if the thickness of the boundary walls 22 and, accordingly, the distance between the guide plates of the uprights 1, i.e. of the housing window 10 accommodating these are enlarged. In this case, the downward-facing boundary surfaces of the boundary walls 22 secure the vertical position of the frame cage 19 in the uprights 1, while the inner regions of these boundary surfaces limit the vertical movements of the bearing chocks 15 of the vertical rollers 16.
  • a universal roll stand consists of two roll stand halves which are connected to one another by cross members 42. These roll stand halves are each made up of a pair of stand bars 40 and 41, which are each connected or connectable to one another by an upper crossbar 43 and a lower crossbar 44.
  • the bearings are between the uprights 40 and 41 of the uprights construction pieces 49 and 50 of the two horizontal rollers 46 and 47 vertically up and down (Fig. 5).
  • On both pairs of uprights 40 and 41 (FIGS. 6 and 7) are outwardly projecting lugs 51 and 52, respectively, which merge into elongated threaded spindles 51a and 52a.
  • the bearing chocks 53 of the vertical rollers 45 are moved horizontally between these projections 51, 52.
  • the pairs of threaded spindles 51a, 52a are connected to these thread-guided horizontal cross members 54 and 55, respectively.
  • the plate-shaped boundary walls 56a of the frame cage 56 are guided with their outer surfaces between the mutually facing guide surfaces 40a and 41a of the stator beam pairs 40 and 41 of the roller stand halves.
  • the inner surfaces of these boundary walls 56a represent guide surfaces both for the vertical adjustment movement of the bearing chocks 49 of the upper horizontal roller 46 guided thereon and for the horizontal adjustment movement of the bearing installation pieces 53 of the vertical rollers 45.
  • the adjustment movements themselves are for the upper horizontal roller 46 by a corresponding or movement of the cross-member 43 and the positioning movements of the vertical rollers 45 by horizontal movements of the horizontal cross-members 54 and 55 in a manner not belonging to the invention.
  • the bearing chocks 53 of the vertical rollers 45 are guided (FIG.
  • the bearing chocks 50 of the lower horizontal roller 47 are connected to the bearing chocks 53 of the vertical rollers 45 in a manner similar to that described in the previous exemplary embodiment (FIGS. 1 to 4) by means of suspension eyelets 57 which can be suspended therein.
  • a vertical movement of the lower horizontal roller 47 with their chocks 50 is effected by the lower cross members in a manner that is also not part of the invention.
  • the plate-shaped boundary walls 56a of the frame cage 56 (FIGS. 6 and 7) have additional lugs 58 with passage recesses 58a and flat vertical contact surfaces 58b. These contact surfaces 58b rest on likewise vertically running, flat guide surfaces 59a of lifting devices 59, which are each arranged in pairs on adjacent stator bars 40, 41 of the roller stand halves and are connected to one another in a geared manner by motors 60 driven via coupling spindles 61.
