    The invention relates to the field of mechanical engineering, in particular to the structures of the equipment for rolling production. The purpose of the invention is to reduce energy loss by optimizing the heat sink. To achieve this, the winder contains a drum 1, a hollow shaft 2 and a mechanism (M) 4 on it moving the heated expansion segments (C) 3 located on it. Between the heated part of the winder and the shaft 2 heat insulation and cooling units are provided. In order to avoid heat loss, pressure sleeves (H) 8 are installed radially relative to shaft 2 between M 4 and C 3. Wall thickness G 8 increases towards C 3. In addition, elements of the cooling unit are also placed between G 8 and M 4. Variation of wall thickness G 8 provides heat sink optimization, 5 з, п, ф-лы, 2 Il.

    one .
    The invention relates to mechanical engineering, in particular to the construction of a rolling mill. The purpose of the invention is to reduce fora energy by optimizing heat removal.
    Figure 1 shows a general view of the winding with a partial cut; figure 2 - a cut A-A in Fig, 1.
    The reel drum 1 comprises a quill shaft 2 on which segments 3 are mounted, which are movable in the radio direction, and also a mechanism 4 for moving the segments. Mechanism A consists of an expandable stem 5 fixed against rotation relative to shaft 2 and mounted therein with the possibility of movement in the axial direction. Slants 6 are made on the rod 5. In the hollows of the hollow shaft 2, 5 wedges 7 jointed with bevels 6 of the rod 5 are radially displaced. Spreading forces are transferred to the segments 3 through pressure sleeves 8, which are mounted on the mounting plate supported on the wedge 7 9. The sleeves 8 are filled with a variable thickness, with the sleeves placed radially relative to the hollow shaft and facing the corresponding segments 3 by a thickened part of the wall 3. Each cooling unit is placed between the mechanism 4 Segments of the segments and the corresponding segment 3. The cooling unit contains channels 10 in the mounting plate 9 connected by pipes 11 with elements (not shown) of their connection to the source of the refrigerant. The parts of the shaft 2 that are not articulated with the mounting plate 9 can be protected by the coatings 2 entering the heat insulating unit, and additional cooling channels 13 are placed between the latter and the shaft 2.
    The mounting plate 9 is also equipped with elements 14 of the heat insulating assembly. The walls of the pressure sleeves 8 are internally and externally covered with thermal insulation, and the external insulation of the sleeves is carried out with the help of thermal insulation elements 14 of the mounting plate, and the internal insulation is due to thermal insulation elements 15 that fill the internal cavity of the sleeves 8.
    For removal of segments 3 to the initial position, a mechanism is provided.

    gate in the form of links 16 and 17. The selection of gaps in the mechanism for moving the segments is provided by the supports of the pressure sleeves 8 in the form of compression springs 18. In accordance with the exemplary embodiment, the compression spring 18 through the plunger 19 acts on the mounting plate 9, so that if there is a gap, the latter is compensated by the springs 1 V
    squeeze. If, when the drum is unclamped, the decompression force exceeds the force of the compression springs 18, these springs are compressed until the expansion wedges 7 are pressed into the mounting plate 9, which
    Pa then, from the direct impact of the expanding wedges 7, is moved outward in the radial direction together with the pressure sleeves 8 and the segments 3,
    20 The support of the segments 3 on the pressure sleeves 8 with the possibility of sliding allows free thermal expansion of the segments 3 when they are heated, and these segments 3 can be mounted console on the shaft 2.
    The cross-sectional shape of the pressure sleeves 8 need not be round, as is the case in the exemplary embodiment. The cross-sectional shape of the liner is selected in. requirements and may be, for example, oval or rectangular. The thickness of the walls of the pressure sleeves may increase in
    35 in the direction of the segments until a continuous bottom of the sleeve is formed, so that the sleeves remain open only in the direction of the expansion device.
    Variable wall shell sleeves 8
    0 ensures the optimization of the heat flux from the segments heated during the operation of the winder 3, without breaking strength. Inside the sleeves 8 there is a temperature difference, and in the zone of
    After low temperatures, the cross section is smaller than in the higher temperature zone. Therefore, the sleeves, taking into account the decrease in the carrying capacity of their material during heating, are 50 optimally loaded.
    The economic effect of implementing the invention is achieved by reducing energy loss.
