Недостатком устройства является то, что изложницы на него должны устанавливаться только уширенной частью кверху, поэтому изложницы, уширяющиеся книзу, необходимо кантовать. Кроме того, при обработке изложниц разной высоты требуется установка сменных подставок.The disadvantage of this device is that the molds on it should be installed only with the broadened part up, so the molds, expanding downwards, must be turned over. In addition, the processing of molds of different heights requires the installation of interchangeable stands.

Изложницы при помощи крана устанавливаются в устройство в· ⁵ горизонтальном положении [21.The closest in design to the proposed technical solution is a device for pushing ingots from ingot molds, containing a horizontally located frame connecting the base plate with the base, which rests on the hydraulic cylinder. Molds with a crane are installed in the device in · ⁵ horizontal position [21.

Недостатком этого устройства является то, что для горизонтальной установки изложниц требуются дополнительные крановые операции, которые можно производить только с холодными изложницами.The disadvantage of this device is that for horizontal installation of molds, additional crane operations are required, which can only be done with cold molds.

Цель изобретения - обеспечение выталкивания слитков из изложниц различных габаритов, уширяющихся как кверху, так и книзу, без их кантовки.The purpose of the invention is the provision of pushing ingots from ingot molds of various sizes, broadening both up and down, without their tilting.

Поставленная цель достигается тем, что устройство снабжено столом, установленным с возможностью горизонтального перемещения по основанию, причем стол имеет сменные подставки, а опорная плита снабжена двумя парами упоров, связанных шарнирно-рычажной системой.This goal is achieved by the fact that the device is equipped with a table installed with the possibility of horizontal movement along the base, and the table has interchangeable stands, and the base plate is equipped with two pairs of stops connected by a hinged-lever system.

Кроме того, подставки выполнены разной высоты, а упоры - ступенчатыми .In addition, the stands are made of different heights, and the stops are stepped.

При раздевании изложниц, уширяющихся книзу, устанавливаемых на подставки 10, упоры 18 сводятся и устанавливаются против слитка (см.The ingot mold with an ingot by a stripping crane is mounted on the appropriate stand (in Fig. 1, the ingot molds are conventionally shown on all three supports), then the sliding table 7 is fed to the working position, in which the axis of the stamp 9 coincides with the axis of the stand • on which the ingot mold is mounted. When undressing molds, expanding downward, mounted on supports 10, the stops 18 are reduced and installed against the ingot (see

ISIS

927413 4 фиг. 3). При этом ступенчатые упоры 17 выводятся из рабочей зоны. Под воздействием усилия рабочего цилиндра 16 штемпель 9 упирается в подставку, которая по направляющим штырям 13 поднимается вместе с изложницей до соприкосновения слитка с упорами 18 (см. фиг. 4). При дальнейшем движении изложницы слиток отделяется от изложницы и падает на дно подставки (см. фиг. 5)· Энергия удара гасится гидросистемой. При обратном движении под воздействием возвратных цилиндров подставка возвращается в исходное положение (см. фиг. 6), стол 7 выдвигается в позицию разгрузки, где изложница и слиток убираются, а на их место устанавливается следующая изложница.927413 4 FIG. 3). When this stepped stops 17 are removed from the working area. Under the influence of the force of the working cylinder 16, the stamp 9 abuts against the stand, which rises along the guiding pins 13 together with the mold until the ingot comes into contact with the stops 18 (see Fig. 4). With further movement of the mold, the ingot is separated from the mold and falls to the bottom of the stand (see Fig. 5) · The impact energy is extinguished by the hydraulic system. During the reverse movement under the influence of return cylinders, the stand returns to its original position (see Fig. 6), table 7 extends to the unloading position, where the mold and ingot are removed, and the next mold is installed in their place.

Изложницы, уширяющиеся г.верху, устанавливаются на подставку 11, после чего стол 7 подается на рабочую позицию, ступенчатые упоры 17 сводятся и охватывают боковые стенки изложницы, а упоры 18 выходят из рабочей зоны (см. фиг. 7)· Под действием рабочего усилия штемпель 9 через штемпель 12 поднимает изложницу и слиток до упора изложницы в соответствующий выступ ступенчатых упоров 17 (фиг.8).The molds, expanding from the top, are mounted on the stand 11, after which the table 7 is fed to the working position, the stepped stops 17 are reduced and cover the side walls of the mold, and the stops 18 leave the working area (see Fig. 7) · Under the action of the working force the stamp 9 through the stamp 12 raises the ingot mold and the ingot all the way to the mold in the corresponding protrusion of the stepped stops 17 (Fig. 8).

При дальнейшем движении штемпеля 9 слиток отделяется от изложницы, -которая падает на подставку (фиг. 9). Ступени на упор 17 располагаются так, чтобы высота падения изложницы не превышала 150-200 мм.With further movement of the stamp 9, the ingot is separated from the mold, which falls on the stand (Fig. 9). The steps on the stop 17 are located so that the height of the mold does not exceed 150-200 mm.

При обратном движении штемпеля 9 слиток может частично или полностью опуститься в изложницу. После разведения ступенчатых упоров 17 стол 7 выдвигается в позицию разгрузки (фиг. 10), слиток с изложницей убирается, устанавливается следующая изложница, и цикл повторяется.With the reverse movement of the stamp 9, the ingot may partially or completely lower into the mold. After breeding the stepped stops 17, table 7 extends to the unloading position (Fig. 10), the ingot with the mold is removed, the next mold is installed, and the cycle repeats.

Технико-экономическое сопоставление предлагаемого устройства по сравнению с известным дает возможность раздевания изложниц как уширяющихся кверху, так и уширяющихся книзу без использования дополнительных кантователей или кранов, сравнительную г простоту приспособления машины для раздевания слитков любой номенклатуры, не затрагивающую конструкцию машины, а связанную только с соответствующими изменениями подставок; увеличенный срок службы уплотнений рабочего цилиндра, обеспечиваемый минимальным воздействием на них теп5 927413 6 нового излучения от слитков; слиток установленным с возможностью горинад цилиндром находится только во зонтального перемещения по основавремя выдавливания, в остальное время он находится на позиции разгрузки на значительном расстоянии от рабочего цилиндра.The technical and economic comparison of the proposed device in comparison with the known makes it possible to strip the ingot molds both expanding upwards and expanding downwards without the use of additional tilters or cranes, the comparative ease of adaptation of the machine for stripping ingots of any nomenclature, not affecting the design of the machine, but only related to the corresponding changes to coasters; increased service life of the working cylinder seals provided by the minimum exposure to heat 5 927413 6 of new radiation from ingots; an ingot with a gorinad mounted with the possibility of gorinad is located only in the horizontal movement based on the extrusion time, the rest of the time it is at the unloading position at a considerable distance from the working cylinder.

Claims

This invention relates to the field of ferrous metallurgy, in particular to the structures of stationary machines for extruding ingots from ingot molds. A device for ejecting ingots from ingots is known, comprising a hydraulic cylinder with a rod and grippers hinged in its case, provided with additional hydraulic cylinders, the rods and cases of which are hingedly connected to the grippers of the SE. The disadvantage of the device is that the molds on it must be installed only the broadened part upwards, therefore the molds that are broadened downwards must be turned over. In addition, when processing molds of different heights, the installation of interchangeable stands is required. The closest in construction to the proposed technical solution is a device for ejecting ingots from molds, which contains a horizontally positioned frame connecting the base plate with the base, into which the hydraulic cylinder abuts. Molds with a crane are installed in the device in a horizontal position 21. The disadvantage of this device is that for horizontal installation of the molds, additional crane operations are required, which can be performed only with cold molds. The purpose of the invention is to provide for the ejection of ingots from molds of various dimensions, broadening both upwards and downwards, without their turning. The goal is achieved by the fact that the device is equipped with a table mounted for horizontal movement along the base, the table having removable supports, and the base plate is equipped with two pairs of stops connected by a hinge-lever system. 39 In addition, the stands are made of different heights, and the stops are stepped. FIG. Figure 1 shows a vertical section through a device for ejecting ingots from molds; in fig. 2 view A in FIG. one; in fig. 3-6 are the schemes for ejection of ingots from molds expanded downwards. On the fit. the same extended upwards. The device for ejection of ingots consists of a base 1, a base plate 2 connected by a frame 3- On the base 1 there are rails on which rollers 5 are mounted, connected by plates 6 to the lower part of the table 7, which are attached to the table 7 is supported on rollers 5- Table 7 has an independent drive (not shown in Fig. 1), ensuring the installation of the table in three strictly fixed positions, in which the corresponding holes of the table 7 are mounted along the axis of the stamp 9. In the opening: of the table 7 are installed the stands 10 for izlo downstairs, and coasters 11 with an intermediate stamp 12 for molds resting upwards. The supports 10 have holes for the guide pins 13. A plunger 15 with a cylinder 1b is fixed to the base 1 by means of the frame 1. Return cylinders mounted between cylinder 16 and base 1 (conventionally not shown in Fig. 1). Stepped stops 17 and 18 are connected to support plate 2, connected by levers 19. Rest stops 17 and 18 can be moved from a separate drive, for example, pneumatic cylinder guides 20 and 21. The drive of the stops in FIG. 2 conventionally not shown. A device for extruding ingots from ingot molds operates as follows. The ingot with the ingot of the stripping crane is installed on the corresponding stand (in Fig. 1, the molds are conventionally shown on all three stands), then the sliding table 7 is fed to the working position in which the axis of the stamp 9 coincides with the axis of the stand on which the mold is installed. When undressing molds, which are broadened downwards, are mounted on supports 10, the stops 18 are retracted and placed against the ingot (see 34. Fig. 3). In this case, the stepped stops 17 are withdrawn from the working area. Under the influence of the working cylinder 16, the stamp 9 rests on the stand, which, along the guide pins m 13, rises together with the mold before the ingot touches the stops 18 (see Fig.). Upon further movement of the mold, the ingot separates from the mold and falls to the bottom of the stand (see Fig. 5). The impact energy is quenched by the hydraulic system. During the reverse movement under the influence of return cylinders, the stand returns to its original position (see Fig. 6), table 7 advances to the unloading position, where the mold and ingot are removed, and the next mold is installed in their place. The molds expanding the r-top are mounted on the stand 11, after which the table 7 is fed to the working position, the stepped stops 17 are reduced and cover the side walls of the mold, and the stops 18 leave the working zone (see Fig. 7). Under the action of the working force, the stamp 9 through the stamp 12 lifts the mold and the ingot up to the stop of the mold into the corresponding protrusion of the stepped stops 17 (Fig. 8). Upon further movement of the stamp 9, the ingot is separated from the mold, on which it falls on the stand (Fig. 9). The steps on the stop 17 are arranged so that the height of the fall of the mold does not exceed 150-200 mm. During the reverse movement of the stamp 9, the ingot may partially or fully descend into the mold. After dilution of the stepped stops 17, the table 7 moves to the unloading position (Fig. 10), the ingot with the mold is removed, the next mold is set, and the cycle is repeated. The technical and economic comparison of the proposed device as compared to the known one allows the mold of both the widening up and the widening down molds without using additional tilters or cranes, the comparative simplicity of adapting the stripping machine for ingots of any nomenclature that does not affect the design of the machine, and the associated with corresponding changes in the stands; extended service life of the seals of the working cylinder, provided by the minimal effect of heat radiation from ingots on them; the bar above the cylinder is only during the extrusion, in the rest of the cylinder it is in the unloading position at a considerable distance from the working cylinder.
