La primera estación de prensado 3 comprende dos dispositivos compactadores motorizados mutuamente superpuestos 4 y 5, uno de los cuales está dispuesto por debajo de la cinta 2 y el otro por encima de la misma a una distancia de la cinta 2 que puede ajustarse según el espesor de la banda de polvos que debe compactarse y según la presión a la que debe realizarse el primer prensado. Generalmente esta presión está comprendida entre 20 y 100 kg/cm^{2}.The first pressing station 3 comprises two mutually overlapping motorized compacting devices 4 and 5, one of which is arranged below tape 2 and the another one above it at a distance from tape 2 that can adjust according to the thickness of the dust band to be compacted and according to the pressure at which the first must be performed pressing. Generally this pressure is between 20 and 100 kg / cm2.
Cada uno de los compactadores 4 y 5 comprende un rodillo motorizado y un rodillo libre, designados respectivamente mediante los números de referencia 40, 41 y 50, 51, alrededor de los cuales pasa una respectiva banda 42, 52. Entre cada par de rodillos 40, 41 y 50, 51 está dispuesta una superficie de rodillos 43 y 53, que consiste en una pluralidad de rodillos libres 430 y 530. La finalidad de las dos superficies de rodillos 43 y 53 es mantener las bandas 42 y 52 presionadas para compactar la banda de material en polvo. La superficie de rodillos 53 puede estar también inclinada en la dirección de avance de la cinta 2 para hacer que la compactación de los polvos de la banda sea gradual.Each of the compactors 4 and 5 comprises a motorized roller and a free roller, designated respectively by reference numbers 40, 41 and 50, 51, around the which passes a respective band 42, 52. Between each pair of rollers 40, 41 and 50, 51 a surface of rollers 43 and 53 is arranged, consisting of a plurality of free rollers 430 and 530. The purpose of the two roller surfaces 43 and 53 is to maintain bands 42 and 52 pressed to compact the material band powdered. The roller surface 53 may also be inclined in the forward direction of the tape 2 to make the Compaction of band powders be gradual.
Las superficies de rodillos 43 y 53 delimitan la zona de compactación (o primer prensado) 100 de la banda de polvos, estando dispuesta corriente abajo de la misma una zona de descompresión 6 en la que la banda de polvos se dilata, en virtud de unos medios adecuados, de manera controlada para evitar la formación de grietas en el artículo compactado.Roller surfaces 43 and 53 delimit the compaction zone (or first pressing) 100 of the powder band, being arranged downstream of it an area of decompression 6 in which the dust band expands, by virtue of adequate means, in a controlled manner to avoid crack formation in the compacted article.
En la forma de realización ilustrada, dicha zona de compresión 6 comprende dos superficies de rodillos superpuestas 44 y 54 dispuestas corriente abajo de las superficies de rodillos 43 y 53 respectivamente. Haciendo referencia a la figura 3, puede apreciarse que la superficie de rodillos 44 es fija y horizontal, mientras que la superficie de rodillos 54 está soportada por una estructura 55 por medio de dos accionadores 56 de tipo hidráulico o mecánico que permiten que la superficie de rodillos se ajuste a nivel y también se incline hacia la cinta 2 para permitir que la masa de polvos compactada se dilate con un gradiente de deformación muy bajo compatible con las características intrínsecas de los polvos.In the illustrated embodiment, said zone Compression 6 comprises two overlapping roller surfaces 44 and 54 arranged downstream of the roller surfaces 43 and 53 respectively. Referring to figure 3, you can it is appreciated that the roller surface 44 is fixed and horizontal, while the roller surface 54 is supported by a structure 55 by means of two actuators 56 of hydraulic type or mechanical that allow the roller surface to adjust to level and also lean towards tape 2 to allow the mass of compacted powders is dilated with a deformation gradient very low compatible with the intrinsic characteristics of the powder.
En otras formas de realización, los medios presentes en la zona de descompresión 6 pueden comprender por ejemplo una placa rígida, no representada, inclinada hacia el plano de avance de la banda de polvos compactada. En este caso, la placa mantiene la cinta 52 presionada contra el artículo compactado.In other embodiments, the means present in the decompression zone 6 may comprise example a rigid plate, not shown, inclined towards the plane of advance of the compacted dust band. In this case, the plate keeps the tape 52 pressed against the compacted article.
La estación de precompactación o primer prensado también comprende unos medios para retener lateralmente los polvos, estando dichos medios en la forma de realización ilustrada en forma de dos bandas 8 y 9 asociadas con el dispositivo compactador 5.The precompaction or first pressing station it also comprises means for laterally retaining the powders, said means being in the embodiment illustrated in form of two bands 8 and 9 associated with the compactor device 5.
Respecto a dicha forma de realización, cada una de las dos bandas pasa parcialmente alrededor del dispositivo compactador 5 y alrededor de dos ruedas desviadoras 101 y 102. Deberá observarse que las ruedas desviadoras son de separación ajustable, con el fin de poder variar la dimensión de la banda de polvos compactados en la dirección perpendicular a la dirección de avance de la cinta según el formato que debe obtenerse.Regarding said embodiment, each of the two bands partially passes around the device compactor 5 and around two diverter wheels 101 and 102. It should be noted that the diverting wheels are separating adjustable, in order to vary the dimension of the band compacted powders in the direction perpendicular to the direction of tape feed according to the format to be obtained.
Las dos bandas 8 y 9 se forman a partir de una mezcla de material elastomérico de alto coeficiente de rozamiento de manera que se comprimen dentro de la zona de compactación entre los compactadores 4 y 5, y a continuación se contraen lateralmente y aumentan su altura en la zona de descompresión, para volver a continuación a su posición de reposo no deformada en las otras partes.The two bands 8 and 9 are formed from one mixture of elastomeric material with high friction coefficient so that they are compressed within the compaction zone between compactors 4 and 5, and then contract laterally and increase its height in the decompression zone, to return to then to its resting position not deformed in the others parts
La contracción lateral de las bandas en las zonas de descompresión permite que se controle la dilatación del artículo compactado en la dirección de la anchura del artículo, es decir, en una dirección perpendicular a la dirección de avance de la cinta 2.The lateral contraction of the bands in the decompression zones allow the dilation of the compacted article in the direction of the width of the article, is say, in a direction perpendicular to the direction of advance of the tape 2.
Deberá observarse que la mezcla de material elástico con la que se forman las dos bandas y su perfil particular son tales que contrarrestan los empujes laterales ejercidos por el material en la cara interior de las bandas durante el prensado.It should be noted that the material mix elastic with which the two bands are formed and their particular profile they are such that they counteract the lateral thrusts exerted by the material on the inside of the bands during pressing.
En la forma de realización ilustrada, las bandas están realizadas en caucho EPDM expandido de célula cerrada.In the illustrated embodiment, the bands They are made of expanded closed cell EPDM rubber.
Además, el perfil de las bandas es tal que durante el prensado, el lado interior de la banda es prácticamente plano y perpendicular a la cinta transportadora 2. Esto minimiza la pérdida de material implicado en la realización del artículo compactado perfectamente en forma de paralelepípedo.In addition, the profile of the bands is such that during pressing, the inner side of the band is practically flat and perpendicular to the conveyor belt 2. This minimizes the loss of material involved in the realization of the article perfectly compacted in the form of a parallelepiped.
En cuanto a este efecto, la figura 4 muestra que el perfil de cada una de las bandas comprende en sus dos caras laterales una parte central deprimida 103 unida a los extremos por una parte curvada 104. Cuando las bandas se deforman por compresión, entre los compactadores 4 y 5, la parte central 103 se desplaza hacia fuera para hacer la cara lateral de la banda sustancialmente plana, tal como se muestra en la figura 5. Por último, deberá observarse que debido a esta compresión, la altura de la sección transversal a través de la banda disminuye aproximadamente un 50% de su altura sin deformar. Este valor puede variar sin embargo según el tipo de perfil utilizado y el material con el que están formadas las bandas.Regarding this effect, Figure 4 shows that the profile of each of the bands comprises on both sides laterals a depressed central part 103 attached to the ends by a curved part 104. When the bands deform by compression, between the compactors 4 and 5, the central part 103 is move out to make the side face of the band substantially flat, as shown in figure 5. By Lastly, it should be noted that due to this compression, the height of the cross section through the band decreases approximately 50% of its height without deformation. This value can vary however according to the type of profile used and the material with which the bands are formed.
