Description
Dispositivo para la solicitación de material plano mediante medios sometidos a presión. Device for requesting flat material by means under pressure.
La invención se refiere a un dispositivo para la solicitación de material plano mediante medios sometidos a presión según el preámbulo de la reivindicación 1. The invention relates to a device for the solicitation of flat material by means under pressure according to the preamble of claim 1.
Por el documento DE 603 07 058 T2 se conoce un dispositivo para la solicitación de material plano mediante un fluido sometido a presión. El dispositivo se compone en cada caso de una vigueta de tobera (vigueta de agua), que en su lado inferior presenta una tira de tobera con una pluralidad de aberturas de salida para un medio sometido a presión, en particular agua. El material o tejido no tejido (nonwoven) tricotado, tejido transportado preferiblemente en forma de una banda bajo la vigueta de tobera, se solicita con los chorros de agua a presión. En un vellón puede generarse así una solidificación o un encocamiento de las fibras, de los filamentos. From DE 603 07 058 T2 a device for the solicitation of flat material by means of a fluid under pressure is known. In each case, the device consists of a nozzle joist (water joist), which on its lower side has a nozzle strip with a plurality of outlet openings for a medium under pressure, in particular water. Knitted nonwoven (nonwoven) material, fabric preferably transported in the form of a band under the nozzle joist, is requested with pressurized water jets. In a fleece, solidification or shrinkage of the fibers, of the filaments can be generated.
La vigueta de tobera conocida se compone de un cuerpo de acero, cuya longitud corresponde a la anchura de trabajo máxima de la máquina. En el cuerpo está incorporada una perforación que se extiende de un lado frontal al otro, que forma una cámara que puede solicitarse con agua a presión. En el lado inferior de este cuerpo está dispuesta una tira de tobera con aberturas de salida, que a través de una pieza designada como mordaza mediante tornillos está fijada al cuerpo de la vigueta de agua. A través de perforaciones las aberturas de salida de la tira de tobera se solicitan desde la cámara de la vigueta con agua a presión. The known nozzle joist is composed of a steel body, the length of which corresponds to the maximum working width of the machine. A perforation extending from one front side to the other is incorporated into the body, which forms a chamber that can be requested with pressurized water. On the lower side of this body there is a nozzle strip with outlet openings, which through a piece designated as a jaw by means of screws is fixed to the body of the water joist. Through perforations the outlet openings of the nozzle strip are requested from the joist chamber with pressurized water.
Una configuración adicional de este dispositivo conocido muestra un cuerpo dividido en el centro de la cámara que se extiende de un lado frontal al otro. Los tornillos, con los que se monta la mordaza en el lado inferior del cuerpo, mantienen unidas de manera estanca también las dos mitades de la vigueta. An additional configuration of this known device shows a body divided in the center of the chamber that extends from one front side to the other. The screws, with which the jaw is mounted on the lower side of the body, hold the two halves of the joist tightly together.
En el dispositivo conocido es desventajoso, que las piezas que van a ensamblarse tengan un tratamiento difícil y costoso, para poder solicitar las viguetas también con alta presión. In the known device it is disadvantageous, that the parts to be assembled have a difficult and expensive treatment, in order to request the joists also with high pressure.
Por el documento DE 10 2005 055 939 B3 se conoce una vigueta de agua, que se compone de una parte superior, una parte inferior y de una cámara de presión así como de una cámara de distribuidor situada por debajo. From DE 10 2005 055 939 B3 a water joist is known, which is composed of an upper part, a lower part and a pressure chamber as well as a distributor chamber located below.
El objetivo de la presente invención es mejorar un dispositivo del tipo genérico. The objective of the present invention is to improve a device of the generic type.
Este objetivo se soluciona por los rasgos característicos de la reivindicación independiente. Perfeccionamientos ventajosos de la invención se obtienen de las reivindicaciones dependientes. This objective is solved by the characteristic features of the independent claim. Advantageous improvements of the invention are obtained from the dependent claims.
Según la invención está previsto un dispositivo para la solicitación de material plano mediante medios sometidos a presión, compuesto por una vigueta de tobera, que en un lado dirigido al material que va a tratarse presenta una pluralidad de aberturas de salida para un medio fluido sometido a presión, estando dispuesta en el interior de la vigueta de tobera una cavidad, y en el que la vigueta de tobera está configurada como un perfil de colada continua generado según un procedimiento de colada continua. According to the invention, a device for the application of flat material is provided by means under pressure, composed of a nozzle beam, which on one side directed to the material to be treated has a plurality of outlet openings for a fluid medium subjected to pressure, a cavity being arranged inside the nozzle joist, and in which the nozzle joist is configured as a continuous casting profile generated according to a continuous casting procedure.
Como perfeccionamiento está previsto lo siguiente: The following is planned as improvement:
- --
- El perfil de colada continua presenta una cavidad para el alojamiento de una tira de tobera que presenta las aberturas de salida. Esta cavidad se ha generado durante la colada continua mediante el correspondiente diseño del molde de colada. The continuous casting profile has a cavity for housing a nozzle strip that has the outlet openings. This cavity has been generated during continuous casting through the corresponding design of the casting mold.
- --
- El perfil de colada continua presenta una cavidad para la solicitación y transmisión del medio que va a procesarse. Esta cavidad se ha generado igualmente durante la colada continua mediante el correspondiente diseño del molde de colada. The continuous casting profile has a cavity for the solicitation and transmission of the medium to be processed. This cavity has also been generated during continuous casting through the corresponding design of the casting mold.
- --
- El perfil de colada continua presenta en su lado inferior una hendidura. The continuous casting profile has a slit on its lower side.
- --
- Las cavidades están unidas entre sí por perforaciones. Las perforaciones así como la hendidura dispuesta en el lado inferior se incorporan posteriormente en el perfil de colada continua (fresado, perforado). The cavities are joined together by perforations. The perforations as well as the slit arranged on the lower side are subsequently incorporated into the continuous casting profile (milling, drilling).
- --
- El perfil de colada continua está fabricado de aluminio. The continuous casting profile is made of aluminum.
La ventaja de la invención consiste en que la sección transversal de la vigueta de tobera está configurada de una pieza como un perfil de colada continua, que para el alojamiento de los elementos que van a preverse presenta aberturas correspondientes en forma de cámaras huecas. Estas cámaras huecas sirven por ejemplo, para el alojamiento de una tira de tobera, de una unidad de cambio y sellado asociada, del suministro de presión y distribución así como dado el caso de elementos previstos adicionales. Las cámaras huecas pueden servir asimismo para el ahorro de material así como para la homogeneización de la distribución de esfuerzos en la solicitación por el medio de presión. En particular el perfil de colada continua está fabricado de aluminio. The advantage of the invention is that the cross-section of the nozzle joist is configured in one piece as a continuous casting profile, which for housing the elements to be provided has corresponding openings in the form of hollow chambers. These hollow chambers serve, for example, for the accommodation of a nozzle strip, of an associated change and seal unit, of the pressure and distribution supply as well as in the case of additional intended elements. The hollow chambers can also be used for material savings as well as for the homogenization of the stress distribution in the application by means of pressure. In particular, the continuous casting profile is made of aluminum.
La integración de los componentes que van a preverse en la vigueta de tobera en correspondientes cámaras huecas que se extienden por la longitud de la vigueta de tobera evita superficies de separación de tratamiento complejo. Las cámaras huecas o cavidades se han generado durante la colada continua mediante el correspondiente diseño del molde de colada. The integration of the components to be provided in the nozzle joist in corresponding hollow chambers that extend along the length of the nozzle joist avoids complex treatment separation surfaces. The hollow chambers or cavities have been generated during continuous casting through the corresponding design of the casting mold.
Dado que por el diseño de la vigueta de tobera según la invención no tienen que unirse componentes entre sí, se elimina también la previsión de una pluralidad de elementos de unión (tornillos), que requieren un gran esfuerzo de montaje y fabricación. La presión aplicada en el interior de la vigueta de tobera se absorbe de manera favorable por la estructura de sección transversal de una sola pieza y que presenta cámaras huecas según la invención. Since the design of the nozzle beam according to the invention does not have to join components together, the provision of a plurality of connecting elements (screws), which require great assembly and manufacturing effort, is also eliminated. The pressure applied inside the nozzle beam is favorably absorbed by the one-piece cross-sectional structure and which has hollow chambers according to the invention.
La invención prevé un modo de construcción de una pieza, con relación al perfil de sección transversal de la vigueta de tobera. Por el contrario la vigueta de tobera según la invención puede estar realizada de manera dividida por su longitud (en la dirección de anchura de máquina), uniéndose entre sí las piezas individuales a través de elementos de unión. De este modo es posible adaptar a partir de distintos elementos de sección a modo de módulo una vigueta de tobera a una anchura de máquina prevista. The invention provides a way of building a piece, in relation to the cross-sectional profile of the nozzle beam. On the contrary, the nozzle joist according to the invention can be made divided by its length (in the machine width direction), the individual parts joining together through connecting elements. In this way, it is possible to adapt a nozzle beam to a planned machine width from different section elements as a module.
Además tiene lugar la explicación de un ejemplo de realización por medio de los dibujos. In addition, the explanation of an embodiment by means of the drawings takes place.
La figura 1 muestra una vigueta 1 de tobera, que se extiende desde un perfil 2 de colada continua que se extiende por la anchura de trabajo de la máquina no mostrada. El perfil 2 de colada continua presenta dos cavidades 3, 4, sirviendo una cavidad 3 como cámara de presión para la solicitación con el medio (fluido) que va a procesarse. La segunda cavidad 4 (cámara de tobera) sirve para alojar una tira 5 de tobera, que presenta una pluralidad de aberturas 6 de tobera. En el fondo de la cavidad 4 en una ranura está encajada una junta 7 (anillo de sellado, medio de sellado circundante). Sobre esta junta 7 se encuentra la tira 5 de tobera. Los medios para fijar la tira 5 de tobera en el interior de la cavidad 4 así como medios adicionales y dado el caso que sirven para la distribución en el interior de la cavidad 5 no están representados. Figure 1 shows a nozzle joist 1, which extends from a continuous casting profile 2 that extends along the working width of the machine not shown. The continuous casting profile 2 has two cavities 3, 4, a cavity 3 serving as a pressure chamber for the solicitation with the medium (fluid) to be processed. The second cavity 4 (nozzle chamber) serves to accommodate a nozzle strip 5, which has a plurality of nozzle openings 6. At the bottom of the cavity 4 in a groove a gasket 7 (sealing ring, surrounding sealing means) is fitted. On this seal 7 is the nozzle strip 5. The means for fixing the nozzle strip 5 inside the cavity 4 as well as additional means and, if necessary, serving for distribution inside the cavity 5 are not shown.
Desde el lado inferior del perfil 2 de colada continua está realizada una hendidura 9 que se extiende por la longitud o casi por toda la longitud del perfil con un ensanchamiento. Los chorros a presión (agua, vapor, gas) generados por las aberturas 6 de tobera se orientan por la hendidura 9 sobre el material que va a tratarse. From the bottom side of the continuous casting profile 2 a groove 9 is made that extends along the length or almost the entire length of the profile with a widening. The pressure jets (water, steam, gas) generated by the nozzle openings 6 are oriented by the groove 9 on the material to be treated.
La solicitación de la cavidad 3 con el fluido que va a procesarse tiene lugar desde uno o preferiblemente desde los dos lados de extremo de la vigueta 1 de tobera. De una manera en sí conocida en los lados de extremo de la vigueta 1 de tobera están embridadas las conexiones necesarias. En uno de los lados de extremo de la vigueta de tobera están previstos también medios para cambiar la tira de tobera. The request of the cavity 3 with the fluid to be processed takes place from one or preferably from the two end sides of the nozzle joist 1. In a manner known per se on the end sides of the nozzle joist 1, the necessary connections are flanged. Means for changing the nozzle strip are also provided on one of the end sides of the nozzle joist.
El fluido conducido hacia la cavidad 3 llega a través de varias perforaciones 8 que se extienden en paralelo entre sí desde la cavidad 3 que sirve como cámara de presión a la cámara de tobera (cavidad 4). Estas perforaciones 8 se han realizado tras generar la hendidura 9 desde el lado inferior del perfil de colada continua. The fluid led to the cavity 3 arrives through several perforations 8 that extend parallel to each other from the cavity 3 which serves as a pressure chamber to the nozzle chamber (cavity 4). These perforations 8 have been made after generating the groove 9 from the bottom side of the continuous casting profile.
La figura 2 muestra el perfil 2 de colada continua en su forma no tratada. Éste presenta únicamente las dos cavidades 3, 4 generadas durante la colada continua. La vigueta 1 de tobera está realizada por tanto de una pieza por su sección transversal. Figure 2 shows the continuous casting profile 2 in its untreated form. This presents only the two cavities 3, 4 generated during continuous casting. The nozzle joist 1 is therefore made of one piece by its cross section.
La vigueta 1 de tobera según las figuras 3 y 4 está construida según el mismo principio que el de las figuras 1 y 2. A diferencia de la forma de realización explicada anteriormente en este caso entre la cámara de presión (cavidad 3) y la cámara de tobera (cavidad 4) está dispuesta una cavidad 3.1 adicional como distribuidor de presión y corriente. El transporte del medio que va a procesarse tiene lugar a través de perforaciones 8.1, 8.2, que se incorporan desde la hendidura 9 en el lado inferior de la vigueta de tobera. The nozzle joist 1 according to figures 3 and 4 is constructed according to the same principle as that of figures 1 and 2. Unlike the embodiment explained above in this case between the pressure chamber (cavity 3) and the chamber of nozzle (cavity 4) an additional cavity 3.1 is arranged as a pressure and current distributor. The transport of the medium to be processed takes place through perforations 8.1, 8.2, which are incorporated from the slit 9 on the bottom side of the nozzle joist.
La figura 4 muestra el perfil 2 de colada continua de la realización según la figura 3 en su forma no tratada. Éste presenta únicamente las cavidades 3, 3.1, 4 generadas durante la colada continua. La vigueta 1 de tobera está realizada así de una pieza por su sección transversal. Figure 4 shows the continuous casting profile 2 of the embodiment according to Figure 3 in its untreated form. This presents only cavities 3, 3.1, 4 generated during continuous casting. The nozzle joist 1 is thus made of one piece by its cross section.
