    The invention relates to metallurgy, in particular to a structural embodiment of slide gates.
    The purpose of the invention is to increase the reliability and ease of use,
    Figure 1 shows the slide gate, a longitudinal section of £ on fi.g, 2 the same, bottom view; in Fig. 3 - section aa in Fig. 2 · in Fig. 4 is one of the embodiments of the clamping device, bottom view; Fig. 5 is the same end view.
    The slide gate consists of a metal casing 1, a stationary refractory hearth plate 2 and a gate assembly 3 with a refractory gate plate 4. A hole 5 in the shaped brick 6, drilling in the hearth plate, in the gate plate and in the drain sleeve 7 connected to the gate plate, form exhaust channel 8. Due to the movement of the gate assembly to the locking position, for example, by means of a hydraulic cylinder 9, this channel is closed.
    The shutter body has a lower supporting wall 10, end walls 11 and side walls 12. For the purpose of collapsible fastening of the shutter on the casing of the bucket. 13, paws 14 extending from the body are provided.
    The groove plate is separately installed in the housing, namely in the recess, and with the help of the supporting surface at the base of the recess is precisely set. The groove plate consists of a plate 17 with a through hole and a heat-insulating strip 18, isolating it from the housing. Similarly, the slide plate consists of 5 plates 19 and a heat-insulating pad 20, the plate resting on a precisely machined abutment surface 21 in the carrier frame 22 in which the slide plate is mounted.
    The case is open on the bottom.
    It has two parallel guide rails 23 that act as the lower supporting wall, which form a guide track 2.4 for the slide carriage 25 and are connected to the side walls by screws. In this case, the guide strips are adjacent to the machined end surfaces of the side walls, which ensures accurate parallel installation and: a predetermined distance between the supporting surface 16 of the hearth plate 2 and the guide track of the slide carriage. The housing of the shutter thereby '- 1 forms a rigid assembly that connects the supporting surface 16 with the guide rails or their guide track 24. From the side, the slide carriage is guided by the machined inner surfaces 26 of the side walls 26' 2.
    The gate assembly 3 is assembled from the gate carriage 25 and the carrier frame 22 separate for it for the gate plate 4.
    For the action of the shutter, a hydraulic cylinder 9 is attached, attached3
    1247 through the yoke 27 to the housing, and its head 28 is included with the capture in the recess of the slide carriage. Two driving pins 29 mounted on the slide carriage enter inside the fitted 5 holes of the carrier frame 22, due to which this frame with the slide plate .4 is carried away in the direction of displacement of the slide carriage. The supporting frame 22 covers, in addition to the gate plate, a refractory drain sleeve 10 .
    A sleeve 30 is screwed into the end wall 11 of the housing, located on the drive side, covering the cylinder rod, which is locked by the countersunk nut 31, and it. the end surface 32 inside, the housing forms an abutment for the slide carriage in position. The slide gate assembly is open. Due to this, 20 holes of two locking plates can be precisely aligned with respect to each other. Clamping devices 33 are inserted into the slide carriage, which are preliminarily pressed against the supporting frame and indirectly on the slide 25 plate 4, the latter can be pressed by the sliding surface 34 to the hearth plate 2. The design of the clamping devices comprises a pack of 35 springs, mainly a set of plate-shaped springs . They are inserted into the longitudinal opening of the device and pre-clamped between the shoulder of the guide pusher 36 and the head of the clamping device. The upper end of the pusher 35 is adjacent to the carrier frame, and the spring package is compressed by a certain amount and the corresponding force through the pusher acts on the carrier frame. 40
    Both clamping devices are screwed into the threaded holes 37 of the slide carriage and tightened until they contact the stop surface. They are inserted into the carriage with the opposite gate 45 false side of the slide plate, which is possible due to the fact that this side of the carriage is free.
    When mounting or disassembling the shutter, the clamping devices are unscrewed 5 ° or released so that there is no pressing force between plates 2 and 4. After removal of the sliding guide rails, the gate assembly 3 and the hearth plate 2 can be removed from the housing. Thus, an easy check or change of the locking plates is possible. Good-
    1, by providing a lockable housing structure with a rigid connection between the supporting surface 16 for the hearth plate and the guiding track 24 on the guide bars 23 of the body, a precisely defined base for the slide carriage in relation to the hearth plate is inevitably obtained. This also preserves the pressing force created by the clamping devices within predetermined narrow limits if, at the end of the assembly, the clamping devices are screwed and pressed against the stop when wrapping to failure.
    In addition, the design of the slide gate ensures that the plane is pressed between the plates 2 and 4 evenly over the sliding surface 34, namely in each position of the gate and also during the actuation of the shutter.
    For this purpose, the clamping devices are inserted into the slide carriage symmetrically with respect to the dimensions of the slide plate 4, namely both in the direction of the shutter displacement and across to it (Fig. 2).
    The design of the slide gate allows accurate wiring of the slide plate during the operation of the gate thanks to the insertion of driving fingers 29 into the openings of the carrier frame. The forceful adhesion of the fingers occurs approximately at the height of the sliding surface and, in addition, the fingers are, as follows from figure 2, on the axis of symmetry of the plate, perpendicular to the direction of displacement. Thanks to this type of lead connection, it is guaranteed that to a large extent co. uniform distribution of specific pressure is stored during the movement of the slide gate.
    The uniformly distributed specific pressure on the sliding surfaces remaining the same is equivalent to the absence of harmful overturning moments. This results in small and uniform wear not only on the sliding surfaces of the locking plates, but also on the metal sliding guides between the slide carriage and the housing. A constant fit without plate clearance also prevents air from flowing along the surface. slip to the resulting melt. These properties of the slide gate make it possible to make a large number of movements openly ”- closed without repair and make the shutter especially suitable for dispensing the melt, for example, when casting molds, especially when casting non-ferrous metals.
    The embodiment of the slide gate presented in FIGS. 4 and 5 differs from the embodiment nafig, 1-3 by the housing design. ”According to FIG. 4 and 5, the guide bars 23 forming a guide track for the slide carriage are integral with the housing or its side walls. In order to, despite this, make it possible to mount and dismantle the gate assembly and the hearth plate, the casing has a removable end wall 11, which is equipped with two side planks or spikes 38, which engage with grooves 39 at the ends of the side walls 12 of the casing. Thus, the end wall 11 can (after removal of the mounting accessories not shown) be displaced outward in the direction of the grooves 39, after which, with the clamping devices turned out, the entire gate assembly can be easily removed from the housing in the direction of the gate shift. It is advisable to perform a removable end wall of the housing on the drive side; then the working cylinder can be mounted directly on the end wall, and when the end wall is removed from the cylinder, the piston rod head 28 and the gate carriage also disengage.
    Unlike the embodiment; 0 in FIG. 1-3, four clamping devices are provided here, symmetrically mounted with respect to the elongated side of the slide plate in the slide carriage.

    a plate 17 with a through hole and a tag insulating gasket 18, isolating it from the housing. Similarly, the gate plate consists of a plate 19 and a heat insulating pad 20, the plate being supported on a precisely machined support surface 21 in the support frame 22 in which the slide plate is installed.
    From the bottom side, the housing is open. It has two parallel guides - 23, which play the role of a h-1 supporting step, which form a guide track 24 for carriages 1 - 25 of the gate and are connected to the side walls with screws. to the treatment. the end surfaces of the side walls, thereby constantly guaranteeing an exact parallel installation and a predetermined distance between the support surface 16 of the bottom plate 2 and the guide track of the slide gate carriage. The body of the gate thus forms a rigid assembly, which has a joint e of the supporting surface 16 with guide bars or their guide track 24. On the side, the slide gate carriage is guided by the inner side surfaces 26 that have been processed; the assembly 3 of the slide gate is assembled from the slide carriage 25 and the supporting frame 22 separate from it for the slide plate 4. A hydraulic cylinder 9 is provided for the slide valve E313, 3 is attached
    through the yoke 27 to the body, and its head 28 enters with a grip into the recess of the gate carriage. Two of the carrier fingers 29 mounted on the carriage slide into the fitted holes of the carrier frame 22, whereby this frame with the slide plate 4 is carried in the direction of displacement of the gate carriage. The supporting frame 22 includes, in addition to the slide plate, a refractory drain sleeve.
    The sleeve 30, the circumference of the cylinder rod, which counteracts an unheated nut 31, and the front surface 32 inside, the body forms the stop for the slide carrier carriage in the position. The slide assembly is screwed into the housing end wall 11 located on the drive side. Due to this, the openings of two locking plates can be precisely aligned with each other. Clamping devices 33 are inserted into the slide carriage, which are pressed against the carrier frame and indirectly to the slide plate 4, which can be pressed against the sliding surface 34 to the bottom plate 2. The design of the clamping devices comprises a package of springs 35, mainly a set of cup springs. They are inserted into the longitudinal opening of the device and are pre-clamped between the shoulder of the pusher driver 36 and the head of the clamping device. The upper end of the plunger rests on the carrier frame, the spring pack being compressed by a certain amount and the corresponding force through the plunger acts on the carrier frame.
    Both clamping devices are screwed into the threaded holes 37 of the gate slide carriage and tightened until they come into contact with the stop surface. They are inserted into the slide carriage on the opposite side of the slide plate, which is possible due to the fact that this side of the carriage is free.
    When mounting or dismounting the valve, the clamping devices are unscrewed or released so that the pressing force between plates 2 and 4 is absent. After removing the detachably fixed guide bars, the node 3 of the gate and the bottom plate 2 can be removed from the housing. Thus, it is possible to easily check or change the locking plates.

    The gift of a lockable body structure with a rigid connection between the support surface 16 for the bottom plate and the guide track 24 on the 5 body guides 23 of the case inevitably results in exactly defined base for the slide gate carriage with respect to the bottom plate. Due to this, the pressing force created by the clamping devices within predetermined narrow limits is also maintained if, at the end of the assembly, the clamping devices are screwed and pressed against the stop while rolling 5 to failure.
    In addition, the design of the slide gate ensures that the pressure on the plane between the plates 2 and 4 is evenly spread over the sliding surface 34, namely, in each position of the slide and also during the activation of the slide.
    For this purpose, the clamping devices are inserted into the slide carriage symmetrically with respect to the dimensions of the slide plate 4, namely both in the direction of displacement of the gate and across to it (Fig. 2).
    The design of the slide gate 0 allows for accurate wiring of the slide plate during the operation of the gate by inserting the driver fingers 29 into the holes of the supporting frame. The force adhesion of the fingers 5 takes place approximately at the height of the sliding surface and, moreover, the fingers are, as follows from figure 2, on the axis of symmetry of the plate, passing perpendicular to the direction of displacement. Due to this type of support connection, it is guaranteed that the uniform distribution of the specific pressure is largely maintained during the movement of the 5-gate valve.
    The same uniformly distributed specific pressure on the sliding surfaces is equivalent to the absence of harmful tilting 0 moments. This results in a small and uniform wear not only on the sliding surfaces of the locking plates, but also on the metal directions of the sliding surfaces between the slide carriage 5 and the housing. Constant adherence without a gap of the plates also prevents air from entering along the surface, sliding to the outgoing melt. These properties of the slide gate make it possible to make a large number of movements open-closed without repair and make the shutter especially suitable for melt dosing, for example, when casting molds, especially when casting non-ferrous metals.
    The version of the slide gate shown in FIGS. 4 and 5 differs from that of FIG. 1-3 housing design. Referring to FIGS. 4 and 5, the guides, the strips 23, which form the guide track for the slide gate carriage, are integral with the housing or its side walls. In order, despite this, to make it possible to mount and dismount the slide assembly and the bottom plate, the housing has a removable end wall 11, which is provided with two side strips or spikes 38, which engage with
    grooves 39 at the ends of the side walls 12 of the casing. Thus, the end wall 11 may (after removing the
    means) move outward in the direction of the grooves 39, after which when 1) 1X clamping devices are turned out — the entire gate assembly can be easily removed from the body in the direction of the gate displacement. It is advisable to make the removable end wall of the housing from the drive side; then the working cylinder can be fixed directly to the end wall, and when the end wall with the cylinder is removed, the piston rod head 28 also leaves the gateway 28. Unlike the version
    in FIG. 1-3, four clamping devices are provided here, symmetrically mounted with respect to the elongated side of the sliding plate in the slide gate carriage.
