    The invention relates to installations for heat treatment of a metal sheet, in particular to an installation for accelerated cooling or hardening.
    A device for processing a metal sheet containing the upper and lower frames with a set of rollers, a device for supplying coolant [1}.
    .In this device it is impossible to process metal sheets of various thicknesses.
    A known installation for cooling a metal sheet containing the upper and lower frames with a set of rollers, a device for supplying coolant and a device for vertical movement of the upper frame ^ 2 ^. In this installation, the upper frame can be moved vertically and, therefore, sheets of various thicknesses can be processed. However, this does not provide a fixation of the position of the frame.
    The aim of the invention is to secure the position of the frames.
    This goal is achieved in that the installation for cooling the metal sheet, containing the upper and lower frames with a set of rollers, a device for supplying coolant and a device for vertical movement of the upper frame, is equipped with screw jacks mounted on the lower frame, while on the upper the frame has holes in which the rods of screw jacks are installed, 'the device for vertical movement of the upper frame is made in the form of hydraulic jacks installed on the upper frame, the rods are which are mounted on the lower frame; the rods of the screw jacks have abutment support against the frames; rods of screw jacks and replaceable gaskets, mounted stops of the upper frame.
    In FIG. 1 shows a longitudinal section of the installation; in FIG. 2 is a section AA of FIG. 1, 'in FIG. 3 is a section BB of FIG. 1, 'in FIG. 4 is a section BB of FIG. 1.
    Installation for cooling the metal sheet contains a stationary lower frame 1 and the upper frame 2, which can be moved vertically. Each of the frames has casings 3 and 4, which fit the roll sets 5 and 6. The casings are connected by pipes 7 to collectors 8, which are connected either to the supply system or to the intake of coolant (the direction of the fluid is shown by arrows).
    Tightness between the side walls of the casings is provided by gaskets 9 made of elastomer or other material. These gaskets have an internal cavity into which fluid is pumped under pressure. A protrusion 10 is made on the inner side of the side wall of the lower frame, which protects the gasket 9 from the effects of high temperatures and from damage when processing a sheet of the largest width.
    Drives that allow the upper frame to be moved 15 relative to the lower frame include hydraulic jacks located approximately one quarter of the installation length from both ends. Each jack has a housing 20 (cylinder) 11, mounted on a forked hinge 12, which allows it to oscillate around a horizontal axis, rigidly fastened to the upper frame 2. The piston rod 13, the lower end of which is jg mounted on the lower frame 1 using a key 14, and the stem 13 itself is supported by the spherical surface 15 of the lower frame 1. Safety valves are provided in the jack power system (not shown in the drawings), calibrated so that they open and release fluid from the system as soon as the vertical force exerted on the top nyu frame, exceed a certain amount.
    A device for ensuring the accuracy of installation of the upper frame 2 relative to the lower frame 1 includes a screw jack mounted on the lower frame 1. The screw jack includes a vertical rod 16 with a thread · β of the lower part interacting with a nut 17 that has teeth
    18. The rod interacts through the teeth 18 with the gear 19. The nut 17 is located between the thrust bearing 20 and the thrust roller bearing 21. The upper part of the rod 16 is guided by a lock 22 equipped with sealing gaskets 23 and is rigidly connected to the side plate of the frame 2. On the frame 2 there is a lock 24, which interacts with the stop 25 of the rod 16. The height of the stop 25 is adjusted using the gasket 26. 'The screw jacks are driven simultaneously by the' transmission shafts 27.
    During installation, the support pads of the upper frame are installed very precisely so as to enable simultaneous and accurate adjustment of the position of the upper frame relative to the lower frame using eight screw jacks operating and moving at the same time. Such adjustment is carried out by lifting the upper frame to a position that, in any case, is higher than the position in which the jacks will have to be during operation of the installation. If during repair it is necessary to leave the upper frame in the uppermost position for a long time, the frame is raised to the position shown in FIG. 1 by a dashed-dotted line, and are locked relative to the vertical columns 28 by means of pins' inserted into the openings 29 and 3Q.
    , During the operation of the installation, the upper frame is supported by eight support units, while the jacks hold the upper frame, which is acted upon by forces directed vertically upward due to the increased pressure of the fluid circulating inside the machine. The valves provided in the hydraulic system of the jacks ensure safety in case of very strong overpressure. and then give the opportunity to move the upper frame up.
