CUCHARA DE COLADA COLADA SPOON
D E S C R I P C I O ND E S C R I P C I O N
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a una cuchara de colada, que resulta especialmente idónea para ser utilizada en máquinas de colada de metales en moldes de arena, cuchara que ha sido concebida y estructurada en orden a facilitar la entrada del metal fundido en el molde de arena, sin necesidad de presurizar la cuchara para el trasvase de dicho metal .The present invention relates to a casting spoon, which is especially suitable for use in metal casting machines in sand molds, a spoon that has been conceived and structured in order to facilitate the entry of molten metal into the sand mold , without the need to pressurize the spoon for the transfer of said metal.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Las máquinas de moldeo de motas comprenden básicamente una cámara de moldeo, alimentada mediante una tolva de arena establecida en la parte superior, estando cerrada dicha cámara mediante un plato delantero desplazable y basculante y mediante un plato trasero previsto en un extremo de un pistón extractor, realizándose la compactación de la arena por presión contrapuesta de ambos platos.The molding machines of motorcycles basically comprise a molding chamber, fed by a sand hopper established in the upper part, said chamber being closed by a movable and tilting front plate and by a rear plate provided at one end of an extractor piston, performing the compaction of the sand by opposing pressure of both dishes.
Una máquina de moldeo vertical de motas se describe en la PCT ES 01/00224, de la que es titular la propia entidad solicitante, máquina que incluye una estación con una cámara que se cierra entre un plato delantero que es desplazable y basculante y un plato posterior asociado a un pistón extractor, formándose una mota en la citada cámara por soplado de arena a través de una tolva o campana superior. La mota obtenida es empujada por un pistón hacia una zona posterior de la fila de motas situadas sobre un transportador que las va enfrentando a una estación de colada. El movimiento de las motas empujadas por el pistón extractor es independiente del movimiento de éstas una vez incorporadas a la fila de motas, donde dicho movimiento es producido exclusivamente por un sistema transportador, de tipo galopante, lo que permite una reducción de tiempo en el ciclo de trabajo, a la vez que se evitan deterioros en las motas, al no ser aplastadas por el citado pistón en su empuje contra la parte posterior de la fila de motas.A vertical molding machine is described in PCT ES 01/00224, which the applicant entity itself owns, a machine that includes a station with a chamber that closes between a front plate that is movable and tiltable and a plate posterior associated with an extractor piston, forming a speck in said chamber by blowing sand through a hopper or upper hood. The speck obtained is pushed by a piston towards a rear area of the row of specks located on a conveyor that faces them at a casting station. The movement of the motes pushed by the extractor piston is independent of their movement once incorporated into the row of motes, where said movement is produced exclusively by a galloping type conveyor system, which allows a reduction in cycle time working, while avoiding damage to the specks, not being crushed by the aforementioned piston in its thrust against the back of the row of specks.
Una estación de colada aparece a su vez en la PCT ES 00/00013, también de la propia solicitante, que presenta la especial particularidad de que además de disponer de un canal principal de colada, que accede al molde por la parte inferior del mismo, incorpora un canal secundario vertical y externo al molde, que desemboca en la parte superior de este último, donde está establecida la correspondiente mazarota, de manera que una vez que el metal fundido ha llenado el molde se obtura el canal principal de colada y se sigue alimentando el metal fundido a través del canal secundario, hasta llenar la mazarota superior, para todo lo cual se utiliza una cuchara de colada presurizada, puesto que dicha cuchara está situada por debajo del nivel inferior del molde.A casting station appears in turn in the PCT ES 00/00013, also of the applicant itself, which has the special feature that in addition to having a main casting channel, which accesses the mold through the lower part thereof, incorporates a vertical and external secondary channel to the mold, which ends at the top of the latter, where the corresponding flask is established, so that once the molten metal has filled the mold the main casting channel is sealed and followed by feeding the molten metal through the secondary channel, until the upper tap is filled, for all of which a pressurized pouring spoon is used, since said spoon is located below the lower level of the mold.
Evidentemente el carácter presurizado de la cuchara complica estructuralmente la misma, con el consecuente encarecimiento que ello supone tanto desde el punto de vista de fabricación como de mantenimiento, a lo que hay que añadir además el consumo energético en la normal operatividad de la cuchara.Obviously, the pressurized nature of the bucket structurally complicates it, with the consequent increase in cost from the point of view of manufacturing and maintenance, to which we must also add energy consumption in the normal operation of the bucket.
DESCRIPCIÓN DE LA INVENCIÓN La cuchara de colada que la invención propone, aplicable a estaciones de colada como la de la PCT ES 00/00013, resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, constituyendo una solución simple y eficaz, que sin suponer problema alguno a la hora de incorporar el metal fundido de dicha cuchara, permite que éste sea trasvasado al molde por simple gravedad, concretamente por efecto de los "vasos comunicantes" , mediante un montaje basculante para la misma que permite que ésta adopte una posición horizontal durante su llenado y una posición vertical durante su vaciado, es decir durante el llenado del molde.DESCRIPTION OF THE INVENTION The pouring spoon that the invention proposes, applicable to casting stations such as the one of the PCT ES 00/00013, solves in a completely satisfactory way the problem previously exposed, constituting a simple and effective solution, which without supposing any problem at the time of incorporating the molten metal of said spoon, allows it to be transferred to the mold by simple gravity, specifically by the effect of the "communicating vessels", by means of a tilting assembly for it that allows it to adopt a horizontal position during its filling and a position vertical during emptying, that is, during filling of the mold.
Para ello la cuchara propiamente dicha está asistida por una plataforma o estructura soporte, con desplazamiento lateral para unirse y separarse de la línea de moldes, y sobre dicha plataforma está montada con posibilidad de basculación la cuchara, con la especial particularidad de que su eje de basculación coincide posicionalmente con la boca de carga de los moldes, de manera que dicho movimiento de basculación no interfiere en la perfecta comunicación entre cuchara y molde, consiguiéndose el movimiento de basculación de la cuchara con la colaboración de un cilindro, preferentemente hidráulico, que a través de una unión cardan y una biela transmite el movimiento al eje de basculación de la cuchara.For this, the spoon itself is assisted by a platform or support structure, with lateral displacement to join and separate from the mold line, and on said platform the spoon is mounted with the possibility of tilting, with the particular feature that its axis of tilting coincides positionally with the loading mouth of the molds, so that said tilting movement does not interfere with the perfect communication between bucket and mold, achieving the bucket swinging movement with the collaboration of a cylinder, preferably hydraulic, which at Through a cardan joint and a connecting rod it transmits the movement to the bucket's tilt axis.
Complementariamente la cuchara propiamente dicha está prevista de una boca de carga y una carcasa metálica que rodea o envuelve la construcción de material refractario y que es capaz de aguantar las altas temperaturas del caldo.In addition, the spoon itself is provided with a loading mouth and a metal housing that surrounds or wraps the construction of refractory material and is capable of withstanding the high temperatures of the broth.
Asimismo, se prevé que la unión entre la piquera de la cuchara se efectúa, bien directamente para lo cual esa piquera arrastra directamente en el molde de arena con una presión regulable y gira sobre la propia arena del molde, o bien la piquera de la cuchara asienta en el molde de arena con una presión regulable, pero para ello gira sobre unos casquillos de material especial, como puede ser de material cerámico o grafito compacto, evitándose para ello el contacto giratorio directo de la piquera de la cuchara sobre el molde de arena que pudiera, deteriorar el mismo.It is also expected that the union between the board of the spoon is effected, either directly for which that runner drags directly into the sand mold with an adjustable pressure and turns on the sand itself of the mold, or the spoon run sits on the sand mold with an adjustable pressure , but for this, it rotates on some bushings of special material, such as ceramic or compact graphite material, avoiding the direct rotating contact of the scoop of the spoon on the sand mold that could damage it.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras referidas puede observarse como la cuchara de colada que la invención propone está destinada a situarse lateralmente con respecto a la línea de moldes (1) , y consiste en un receptáculo (2) con su correspondiente boca de llenado (3) y conducto de salida (4) rematado en el correspondiente orificio (5) enfrentado a la entrada a los canales de alimentación de metal fundido al molde, con la especial particularidad de que el citado conducto de salida (4) , en la situación inicial, de reposo y llenado de la cuchara (2), la mostrada en la figura 1, adopta una disposición inclinada hacia arriba, de manera que el orificio de salida (5) queda situado por encima del nivel del metal fundido (6) que constituye la dosis máxima prevista para dicha cuchara. El llenado del molde se realiza por simple basculación de 90° de la cuchara, que pasa a adoptar la posición representada en la figura 2, en la que por la longitud del conducto de salida (4) el receptáculo (2) de la cuchara, que alberga mayoritariamente al metal fundido (6) , queda situado por encima de dicho molde y en condiciones de llenar integralmente este último por encima de su mazarota, por simple gravedad.In view of the aforementioned figures, it can be seen how the pouring spoon that the invention proposes is intended to be positioned laterally with respect to the mold line (1), and consists of a receptacle (2) with its corresponding filling mouth (3 ) and outlet duct (4) finished off in the corresponding hole (5) facing the entrance to the molten metal feed channels to the mold, with the particular feature that said outlet duct (4), in the initial situation , resting and filling the spoon (2), the one shown in figure 1, adopts an upwardly inclined arrangement, so that the outlet opening (5) is located above the level of the molten metal (6) that constitutes the maximum expected dose for said spoon. The filling of the mold is carried out by simple tilting of 90 ° of the spoon, which goes on to adopt the position represented in Figure 2, in which the receptacle (2) of the spoon, by the length of the outlet duct (4), which mostly houses molten metal (6), is located above said mold and in a position to fill the latter completely above its mazarot, by simple gravity.
Para que la cuchara no interfiera en el avance de la línea de moldes (1), dicha cuchara está montada sobre una plataforma o estructura soporte (7) , desplazable lateralmente sobre guías (8) con respecto a la línea (1) , en orden a aproximarse y distanciarse de la misma, plataforma (7) sobre la que está montado un cilindro hidráulico (9) que, con la colaboración de una unión tipo cardan (10) y una biela (11) , suministra al eje (12) soporte de la cuchara (2) el necesario movimiento de basculación para pasar de la posición representada en la figura 1 a la de la figura 2 y viceversa, eje (12) montado sobre cojinetes (13) y que, como anteriormente se ha dicho, coincide coaxialmente con el orificio de salida o piquera (5) del conducto (4) de la cuchara.So that the spoon does not interfere with the advance of the mold line (1), said spoon is mounted on a platform or support structure (7), laterally movable on guides (8) with respect to the line (1), in order to approach and distance from it, platform (7) on which a hydraulic cylinder (9) is mounted which, with the collaboration of a cardan-type joint (10) and a connecting rod (11), supplies the bucket support (2) to the shaft (2) with the necessary tilting movement to move from the position shown in figure 1 to the of figure 2 and vice versa, shaft (12) mounted on bearings (13) and which, as previously mentioned, coaxially coincides with the outlet or pinhole (5) of the duct (4) of the bucket.
Las figuras 4 y 5, muestran finalmente de forma esquemática la unión entre la cuchara (2) y la línea de moldes (1), en la primera solución, la de la figura 4, la piquera de la cuchara u orificio de salida (4) , se asienta en el molde de arena con una presión regulable y efectúa el giro de esa piquera sobre la propia arena del molde.Figures 4 and 5, finally show schematically the connection between the spoon (2) and the mold line (1), in the first solution, that of Figure 4, the spoon spike or exit hole (4 ), it sits on the sand mold with an adjustable pressure and rotates that bite on the mold sand itself.
En la figura 5, la piquera de la cuchara asienta y gira a través de unos casquillos intermediosIn figure 5, the scoop of the spoon settles and rotates through intermediate bushings
(14) evitando con ello el contacto directo entre la piquera de la cuchara y el molde de arena, ya que si se efectúa el giro entre ambos de modo directo, pudiera llevar con ello un deterioro del citado molde.(14) thereby avoiding direct contact between the spoonbill and the sand mold, since if the rotation between the two is carried out directly, this could lead to deterioration of said mold.
Estos casquillos son de un material especial que aguanten las altas temperaturas, tal y como materiales cerámicos, grafito compacto, etc. These bushings are of a special material that withstand high temperatures, such as ceramic materials, compact graphite, etc.
