    The invention relates to rolling production, and concerns the working stands of a rolling mill with two or more pairs of beds, mounted in them by set screws, connected by transverse planers, having the possibility of movement in the direction of the longitudinal axis of the screws with the pillow assembly with rolls located between the beds. The purpose of the invention is to increase the versatility of the cage. The set screws 11, 12, 13 and 14 are mounted in the cage beds stationary and vertically in relation to them, and the pressure nuts 27, 28 and 29, 30 are installed in the transverse cross-members 23, 24 and 25, 26 with the possibility of rotation from the drive. The drive may be mounted on transverse cross member 31 and 33 and connected to pressure nuts 36 of the drive element 37, but, as an embodiment, may include a separate additional cross spreader mounted on the cross screws parallel to the transverse cross beam or across it. With an additional cross member, the drive elements are connected, which can be connected to the pressure nut. The crate is applicable for various types of constructions. it can also be used after dismantling the support frame for the supports of the vertical rolls as a horizontal stand with normal roll diameter, without vertical fixed crossbars installed in conventional universal stand constructions on the side of the stand and preventing the use of such roll diameters. Removal of a set of horizontal rolls from the roll supports is possible with the transverse traverse pivoted up or with the transverse traverse shifted up and down, respectively. Horizontal rolls can be mounted independently of one another. By setting the lower horizontal rolls, the height of the stand can be changed. This makes it possible to create a cage with high bed rigidity and precision of manufacture. 11 hp ff, 5 ill.

    Pami 7 and 8 are mounted bearing frames 20 and 21 for a pair of vertical rolls 22.
    On the set screws 11 and 12, the upper transverse cross braces 23 and 2k and the lower transverse cross braces 25 and 26 are fitted, respectively, with the possibility of their longitudinal movement relative to the screws due to the pair of pressure nuts 27 and 28 and 29 and 30 that are installed with rotation and having threaded screws compound. Above and below the transverse traverse 23 and 2 and 25 and 26 are respectively the upper additional transverse traverse 31 and 32 and the lower additional transverse traverse 33 and 3, mounted on the screws 11 and 12 and 13 and 14.
    I
    In the exemplary embodiment, the additional traverses are arranged respectively across the upper transverse traverse 23 and 2k and the lower transverse traverse 25 and 26 and are connected with bolt-set screws using a pair of drive nuts 35 and 36 fixed in them. The latter are jointly adjusted by on the additional transverse cross members 31 and 32 and 33 and 34 by the engines 37 through the universal spindles 38 and transmit the drive forces to the push nuts 27 and 28 and 29 and 30 mounted in the cross crossbars 23 and 2k and 25 and 26.

    Bearing frames 20 and 21 for a pair of hand rolls 22 have support surfaces 39 and 40 (not shown), on which the push nuts 41 and 42 (not shown) are supported. Thus, the supporting frames 20 and 21 form, respectively, transverse cross-beams, which (unlike the upper and lower additional cross-beams, form a threaded connection with set screws 15 and 16, and can be displaced along screws 15 and 16 by pressing nuts 41 and 42, which here secured in additional cross braces 43 and 44. The pressure nuts 41 and 42 are rotated by gear teeth 45 and 46, located in the additional cross braces 43 and 44. These gears are driven, respectively, as in addition transversal grass, motors 47 through universal spindles 48, the longitudinal axis of which runs inclined to the horizontal.
    The transfer of force from the drive nuts 35 and 36 and 45 and 46 to the pressure nuts 2 / -30 and 41 and 42 occurs either directly (Fig. 2), and the drive nuts 35 and 36 and 45 and 46 are also bolted together. with the corresponding set screws 11-16, or due to the fact that they, at their ends, are connected to the corresponding pressure nuts 27-30 by spline joints 49 and 50 (Fig. 1).
    The upper transverse cross member 23 and 24 are supported by side bearing protrusions. 51 on the push pushers 52 mounted on the beds 1 and 2 of the piston cylinders 53, while the cushions 17 of the upper horizontal rolls 19 are mounted on the rods 54 of the piston cylinders 55, which are mounted with the possibility of removal on the bearing lugs 56 located on the transverse cross rails 23 and 240 The upper and lower transverse cross member 23-26 have pressure ledges 57-60, (which load the pads 17 and 18 of the upper and lower horizontal rolls o
    The upper horizontal guides 61 for rolling are hingedly suspended in the side racks 62, which are connected to the upper transverse rails 23 and 24 by supporting plates 63, while

    while the lower horizontal guides 64 are hingedly attached to the uprights 65, which are respectively mounted on the supporting plates 66 connected to the lower transverse cross member 25. The vertical rolling guides 67 (Fig. 3 and 4) are also hinged to the cushion 68 with the hinged support 69 and are connected to another hinge support 70 mounted on the guide 71 located on the lateral guide 7, 8 of the stand, with the rod 72 of the pusher 73, the free end of which is rigidly connected to the supporting frames 20 and 21 of the pillow 68. On the lateral directions their projections 7 and 8 are within the piston cylinders 74 the jacks 73 are loaded opposite the place of installation of push nuts 41 and 42 toward the supporting frames 20 and 21.
    The pads 17 and 18 of the horizontal rolls 19 are pressed by protrusions 57 and 58 or 59 and 60 of the transverse cross member 23 and 24 or 25 and 26 are loaded from above or below in a given direction of movement, when the engines 37 of the respective additional transverse cross member and 32 or 33 and 34 lead to the action of the push nuts 27 and 28 or 29 and 30 through the drive nuts 35 and 36. At the same time, the additional transverse traverse 31 and 32 or 33 and 34 simultaneously track the movement of the transverse traverse 23 and 24 or 25 and 26 in the prescribed direction. In addition, they can remain fixed in the upper position, when the drive nuts 49 and 50 (Fig. 1) at the ends of the mounting screws 11 and 12 or 13 and 14 are fixed for rotation and the drive force through the spline connections 49 and 50 s. axially cut teeth are transferred to the pressure nuts 27 and 28 or 29 and 30. In this case, the movement of the upper horizontal rollers 19 with their pillows 17 and 18 with respect to the cross-member cross members 23 and 24 is carried out using piston cylinders 55, while the rods cylinders 53 support transverse traverse 23 and 24 when and x movement in two installation directions.
    The movement of the two support frames 20 and 21 in the mounting directions is ensured by means of those installed and fixed on the additional 715
    The body cross-members 29 and kk of the push nuts P and k2, these nuts, since they only fit their ends to the supporting surfaces 39 or kQ of the support frames 20 and 21, can only move them in the direction of the rolling, while movement in the opposite direction, the pusher 73 is carried out. The vertical rolling guides 67 track these movements by means of their hinged attachment 69 to the cushion 68 of the vertical rolls 22 and the hinge 70 to the rod 72, connected to the corresponding support frame 20, 21.
    The upper transverse cross member 23 and 2k can be rotated from the working position (as shown by solid lines, fig. K, pos. 23) to a position that allows the horizontal rollers 19 with their cushions 17 and 18 to be dismounted upward (dash-dotted line, pos., The nuts 27 and 28 remain on the screws 11 and 12 at the same time. The upward displacement of the horizontal rollers 19, for example with a crane, does not prevent the respective additional cross members 31 and 32, since they are located across the cross members 23 and 2k.
    Similarly, frames 20 and 21, which receive vertical rolls 22, can be removed. They can also be lifted vertically upwards, for example with a crane, from screws 15 and 16, with guide plates 67 for rolling, which remain on the respective support frames 20 and 21. The horizontal position of the longitudinal axis of the universal spindles 48 allows the additional transverse cross bars 43 and 44 to be moved with the half rolls 75 mounted on the shanks of the horizontal rolls.
    In accordance with the operational and design requirements in the proposed rolling mill stands, cross-beams can also be used, on which the drive nut elements of the push nuts are located; In addition, it is possible to use in additional transverse cross-beams for supporting frames of vertical rolls the fastening of pressure nuts in additional transverse cross-beams, also in additional transverse
    eight
    traverse, loading horizontal rolls. Accordingly, it is possible to execute drive with a spline connection, i.e. with axially cut teeth, the drive nuts can be made either as a worm gear, connected with a splined connection consisting of two parts, or as a single piece.
    The advantages of the proposed stand in comparison with the known one are that its design provides independent movement of transverse cross members, which, in turn, makes it possible to use the stand in a two-roll version, to reduce the dimensions of the bed, to simplify mounting and installation of mounting screws, to simplify machining cutting in the manufacture of bedding.
