    The invention relates to the processing of metals by pressure, in particular to rolling mills, and can be used to form fins on pipes (silver pipes are used for heat exchangers in many sectors of the national economy).
    A device for mounting a roll in a cross-rolling mill stand is known, comprising a housing mounted on a stand stand with a roll attachment mechanism and an axial feed mechanism l,
    A disadvantage of the known device is the complexity of the design, the difficulty of installation and the control of correct operation of the device.
    . The purpose of the invention is to reduce the labor intensity during readjustment of the device as well as to ensure adjustment of its position.
    To achieve this goal, a roll mounting device in the stands of a cross-rolling mill contains a housing mounted on the stand of the stand with a roll fastening mechanism and an axial roll feed mechanism in the form of Two successively placed in the housing of hydraulic cylinders and two pistons mounted in them connected between a rod, at one end of which an emphasis is made with interchangeable gaskets installed on the side of the body, the first of the hydraulic cylinders mounted in the body on the thread, and the second one Installed in the housing with the possibility of axial reciprocating movement, and the roll attachment mechanism is designed as a slider placed in the bottom part of the second hydrocyliro, one end of which is connected to the roller by means of the flange and the end of the axial feed mechanism stem to the BTOpbjM through the flange moisture
    FIG. 1 shows the proposed device with the tool clamped during rolling; in fig. 2 - the same, during the termination of the formation; in fig. 3 - the same, with a weakened fit tool; in fig. 4 - rolling mill.
    - On the frame 1 of the rolling stand, three housings 1 are mounted rotatably with a precisely adjusted position angle. Two cylinders 3 and 4 are sequentially placed in case 2, hydraulic cylinder 3 is mounted on the thread in the case, and hydraulic cylinder 4 is axially reciprocating, In hydraulic cylinder 3, piston 5 is mounted, and piston 6 is located in hydraulic cylinder 4. Pistons 5 and 6 are connected .1 between themselves rod 7. At one end of rod 7, an emphasis 8 is mounted with removed gaskets 9. A hole is made in the bottom of hydraulic cylinder 4, in which slider lOj, one end of which is connected with roller 11 by rome 11 and another by means of flange 13 by means of rod 7. During rolling, the external gusset 5 is hydraulically moved to the upper position and the amount of movement is controlled by the thickness of spacer pads 9 with which the abutment 8 of the rod 7. The inner cylinder 4 is then moved to its lowest position. The axial movement of the internal hydraulic cylinder 4 is limited by the extension of the slide 10, the position of which is determined by the contact of the grippers 14 and 15, as well as the thickness of the part of the frame} that is between the pressure flange 16 of the slide 10 and the bottom of the internal hydraulic cylinder 4. The opposite direction to each other pressed against one another, the corresponding surfaces of the rod 7, the slide 10 and the hub 11 accurately determine the position of the roll 12 relative to the base, which is the outer surface of the spacers. The position of the base relative to the rolling axis is established by moving the external hydraulic cylinder 3 in the screw nest of the housing 2 or by changing the thickness of the spacers 9. During the manufacture of the fins, the piston 5 is hydraulically moved to the upper extreme position in order to leave part of the pipe in an unrecovered form. After a predetermined time, a corresponding change in pressure in the hydraulic system, the piston 5 returns to its previous position. During this, the movements together with the piston 5 and the rod 7 move the slider 10 with the inner hydraulic cylinder 4 and the yoke 1 1 with the roller 12, while maintaining the tool fixing constant. The replacement of the roll 12 consists in the splitting of the chambered 11, previously between the slider 10 and the inner
    31
    hydraulic cylinder 4, moving the tool away from the rolled pipe and correctly replacing the free set of the frame with the tool. The splitting of the chambers consists in moving the inner cylinder 4 upward with a fixed rod 7 so that the bottom comes in contact with the stop flange 13 of the slide 10. Then between the pressure flange 13 of the slide 10 and the ring 11 there is a gap sufficient for free maneuvering with the sleeve 11. Moving the tool away from the rolled pipe enters further moving internal hydraulic cylinder 784
    4 and up, together with it, the slider 10 and the hive 11. It is necessary to push back a value (about 20 mm) sufficient to stop the contact of the rolling disks with the profiled edge, which is limited by the depth of the socket, the bottom of which is supported by the slider 10 on the rod 7. After such a move of the frame with the roll from the rolled
    Pipes can be freely manipulated with a roll set.
    The proposed device will ensure the reliability of fastening of the instrument, as well as its adjustment
