Изобретение относитс к области черной металлургии и может быть и опользовано при подготовке изложниц дл разлквки стали.The invention relates to the field of ferrous metallurgy and may be used in the preparation of molds for steel casting.

Известно устройство дл чистки изложниц, содержащее укрепленные на стойке на-нравл ющую воронку, служащую дл установки изложницы по оси рабочего органа, и рабочий орган со щетками 1.A device for cleaning molds is known, which comprises a funnel that is fixed on a rack, which serves to install the mold along the axis of the working member, and a working member with brushes 1.

Однако такое устройство не предусматривает выполнение операций удалени отработан .ных стаканчиков и удаление шлака, оставше:гос на стенках изложницы.However, such a device does not provide for the removal of waste cups and the removal of slag, the rest: state on the walls of the mold.

Известны также устройства дл удалени отработанных 1стаканчико1в 2 и устройство дл очистки изложниц от шлака под действием центробежной силы рабочим органом, в котором служат -металлические канаты 3.Also known are devices for removing waste glass in 2 and a device for cleaning molds from slag under the action of centrifugal force by the working body in which metal wires 3 are used.

Однако указанные устройства обеспечивают вынолнение лишь одной операции по подготовке изложниц.However, these devices provide the completion of only one operation for the preparation of molds.

Цель изобретени - сокращение времени подготовки изложницы за счет совмещени операций чистки стенок изложницы, удалени отработанного стаканчика из донного отверсти и удалени мусора из полости изложницы .The purpose of the invention is to reduce the time of preparation of the mold by combining the operations of cleaning the walls of the mold, removing the waste cup from the bottom hole and removing debris from the cavity of the mold.

Это достигаетс тем, что в стойку предлагаемого устройства вмонтирован полый приводной вал, в котором установлен рабочий вал, св занный снизу с полой подпружиненнойThis is achieved in that a hollow drive shaft is mounted in the rack of the proposed device, in which a working shaft is mounted, which is connected below with a hollow spring-loaded

муфтой, а сверху на рабочем валу укреплены цепной дробитель шлака и пуансон.coupling, and on top of the working shaft reinforced chain slag crusher and punch.

На фиг. 1 показано предлагаемое усгройство дл подготовки изложниц, общий вид; на фиг. 2 - то же, продольный разрез.FIG. 1 shows a proposed arrangement for preparing molds, a general view; in fig. 2 - the same, longitudinal section.

Устройство дл подготовки изложницы 1 состоит из направл ющей воронки 2, служащей дл ориентации изложницы по оси рабочегоThe device for preparing the mold 1 consists of a guide funnel 2, which serves to orient the mold

органа, стойки 3, опирающейс на основание 4, на которой укреплены на рычагах 5 спаренные металлические щетки 6, которые внизу шарнирно креп тс к стойке 3, а вверху удерживаютс в заданном положении шар ирно т гами 7 с отжимающи ми пружинами 8. Над щетками 6 установлены отбойники 9.body, rack 3, resting on the base 4, on which are fixed on the levers 5 twin metal brushes 6, which are hinged at the bottom to the rack 3, and at the top are kept in a predetermined position a ball and 7 with clamp springs 8. Above the brushes 6 installed bump stops 9.

В стойку 3 вмонтирован полый приводной вал 10. Внизу на него жестко посажено коническое зубчатое колесо 11, которое находитс в зацеплении с приводной коничеокой шестерней 12. Колесо И и шестерн 12 с валом 13 удерживаютс подшипниками качени И и корпусом 15, жестко св занным с основанием 4.A hollow drive shaft 10 is mounted in a rack 3. A conical gear wheel 11 is rigidly seated on it below, which is meshed with a driven conical gear 12. The wheel And and gear 12 with the shaft 13 are held by rolling bearings And and the housing 15, which is rigidly connected to the base four.

Сквозь полый вал 10 проходит рабочий валThrough the hollow shaft 10 passes the working shaft

16, который внизу через фрикционный диск 1716, which is down through the friction disc 17

пружиной 18 прижат к дисковой полумуфтеthe spring 18 is pressed to the coupling half

19, жестко закрепленной на полом валу 10.19, rigidly mounted on the hollow shaft 10.

Claims

The force of the springs 18 through the support bearing 20 and the bolster 21 is adjusted by the cup 22 connected to the disk coupling half 19 of the threaded connection. An open disk 17, a disc coupling half 19, a spring 18, a bearing 20, a pod NIK 21 and one hundred: a cann 22 together constitute a torque limit clutch. At the top of the working shaft 16 there is fixed a chain crusher 23 of slag with a safety ring 24 and a punch 25, which serves to push the glass cup out of the bottom hole of the mold 1. The device works in the following way. Figure 1, tipped with BiBepx bottom, lowered the crane on the working body. The guide funnel 2 and the bump stops 9 orient the mold along the axis of the working body. The brushes 6 pull the springs 8 through the levers 5 and enter the cavity of the mold 1. The drive of the hollow shaft 10 is turned on and the torque through the disk 17 and the coupling half 19 is transmitted to the working shaft 16. When it is rotated by the centrifugal force of the chain, the crusher 23 disperses and, a blow to the walls of the mold 1 will beat off the slag remaining on them. Brushes 6, pressed by the force of the springs 8 to stevkam, clean them. The mold 1 is lowered to unor in the punch 25, which enters the cavity of the chamotte hundred of the small fish, and the mold 1 by its weight weighs down npy, vnHy 18, while the shaft 16 comes out of the engagement with the hollow shaft 10 and stops rotating. The spring 18 settles before the lock with a safety ring 24 of the slag crusher 23 into the base 4 of the rack 3. At this moment, the weight of the mold through the chamotte glass is not stored on the plunger 25 and the weight of this weight is exhausted. When lifting the mold 1, the spring 18 engages the working shaft 16 into engagement with the hollow shaft 10 and the action of the crusher 23 is resumed. Metal brushes 6 clean the walls of the mold again. Purification products fall down and by gravity are sent to the garbage bin. The prepared mold 1 is returned to its original position by means of a tilting device and is placed on a pallet. The proposed device allows improving the quality of wall cleaning and durability of metal brushes, combining the cleaning operation with an automatic ejector of a used cup, increasing the efficiency of using a crane and reducing the number of workers in the area of preparation of molds. The invention The apparatus for the preparation of molds, containing a guide funnel fixed to the rack and a working body with brushes, characterized in that, in order to reduce the time of preparation of the mold, a hollow drive shaft is mounted in the rack, in which the working shaft connected from the bottom to the hollow is mounted spring-loaded clutch, and on top of the working shaft reinforced chain slag crusher and punch.
