Description
Dispositivo para influir de forma regulable en las fuerzas de rozamiento entre las superficies de guiado y superficies de contacto de colisas de cojinete de los cilindros, guiadas en las aberturas verticales de bastidor de bastidores de laminación.Device to influence in an adjustable way frictional forces between the guiding surfaces and contact surfaces of cylinder bearing collars, guided in the vertical rack openings of racks lamination.
La invención se refiere a un dispositivo para influir de forma regulable en las fuerzas de rozamiento entre las superficies de guiado y superficies de contacto de colisas de cojinete de los cilindros, guiadas en las aberturas verticales de bastidor de bastidores de laminación.The invention relates to a device for influence the friction forces between the guiding surfaces and colisa contact surfaces of cylinder bearing, guided in the vertical openings of casting rack frame.
Los dispositivos de este tipo sirven para contrarrestar las vibraciones que se producen con frecuencia al laminar bandas de chapa en bastidores de laminación múltiple, en especial a velocidades de laminación elevadas, que conllevan el peligro de que surjan problemas de vibración. Estas vibraciones pueden conducir a daños superficiales, como las llamadas marcas de retemblado en las bandas, y también tienen un efecto negativo en los tiempos de vida útil de los cilindros. Cuando para evitar estas vibraciones es necesario laminar a menores velocidades de laminación, se reduce la productividad del tren de laminación con la consecuencia de que se producen mayores costes.Devices of this type serve to counteract vibrations that occur frequently by laminating sheet strips in multiple lamination racks, in especially at high rolling speeds, which entail danger of vibration problems arising. These vibrations they can lead to superficial damage, such as the so-called brands of reassembled in the bands, and also have a negative effect on the lifespan of the cylinders. When to avoid these vibrations it is necessary to laminate at lower speeds of rolling, the productivity of the rolling mill is reduced with the consequence of higher costs.
Ya se ha propuesto combatir estos problemas de vibración mediante la generación de una fuerza de rozamiento, entre las superficies de guiado y contacto de las aberturas verticales de bastidor y las colisas de cojinete, con cuerpos huecos que podían extenderse por medio de presión hidráulica. Estos cuerpos huecos extensibles se montan en las aberturas verticales de bastidor de los bastidores de laminación e impulsan las superficies de apriete de las colisas de cojinete. Si bien estos cuerpos huecos llevan a un aumento de las fuerzas de rozamiento entre las superficies de guiado y contacto de las aberturas verticales de bastidor y las colisas de cojinete, presentan sin embargo el inconveniente de que impulsan la superficie de contacto de las colisas de cojinete sólo de forma bombeada, y no uniformemente por toda la superficie. Una modificación de las intensidades de apriete no puede provocarse o sólo puede hacerse de forma muy dificultosa. No puede provocarse, o sólo puede hacerse de forma muy dificultosa, una fuerza definida de apriete y rozamiento.It has already been proposed to combat these problems of vibration by generating a frictional force, between the guidance and contact surfaces of the vertical openings of frame and bearing collars, with hollow bodies that could Spread through hydraulic pressure. These hollow bodies Extendable are mounted in the vertical frame openings of the lamination racks and propel the clamping surfaces of bearing collars. While these hollow bodies lead to a increased frictional forces between the surfaces of guidance and contact of vertical frame openings and bearing collars, however, have the disadvantage that propel the contact surface of the bearing collars only pumped, and not evenly across the surface. A modification of the tightening intensities cannot be caused or It can only be done very difficult. It can't be caused, or it can only be done in a very difficult way, a definite force of tightening and friction.
La invención se ha impuesto la tarea de mejorar los dispositivos genéricos de tal modo, que haga posible la impulsión en toda la superficie de las superficies de apriete de las colisas de cojinete con fuerzas de apriete variables, para generar fuerzas de rozamiento definidas, con independencia de las respectivas condiciones de la técnica de laminación.The invention has set itself the task of improving generic devices in such a way that makes possible the entire surface drive of the clamping surfaces of bearing collars with variable clamping forces, for generate defined friction forces, regardless of respective conditions of the lamination technique.
Esta tarea es resuelta por medio de que una de las dos superficies de contacto de la colisa de cojinete hace contacto con una superficie de guiado de la abertura vertical de bastidor, y la otra superficie de contacto está formada por una placa plana, aplicada de forma desplazable en la pared de la abertura vertical de bastidor, que puede someterse a presión por detrás de forma precalculada y ajustable.This task is solved by means of which one of The two contact surfaces of the bearing colisa makes contact with a guide surface of the vertical opening of frame, and the other contact surface is formed by a flat plate, scrollable applied to the wall of the vertical rack opening, which can be pressurized by behind precalculated and adjustable.
El dispositivo permite generar fuerzas definidas de apriete y rozamiento en las colisas de cojinete en la abertura vertical de bastidor del bastidor de laminación, puenteando el juego de funcionamiento, es decir, precalcular de forma específica fuerzas definidas de apriete y rozamiento con independencia de las condiciones de la tecnología de laminación.The device allows to generate defined forces tightening and friction in the bearing collars in the opening vertical of rolling frame frame, bypassing the operating game, that is, precalculate specifically defined forces of tightening and friction regardless of Lamination technology conditions.
La invención se explica con más detalle con base en el ejemplo de ejecución representado en el dibujo.The invention is explained in more detail based in the example of execution represented in the drawing.
El dibujo muestra en representación esquemática la vista parcial de una abertura vertical de bastidor SF, formada en los largueros de bastidor SH1, SH2, de un bastidor de laminación no mostrado por lo demás, según se mira en la dirección del eje del cilindro. La colisa de cojinete LE del cilindro W se guía, con movimiento ascendente y descendente, en la abertura vertical de bastidor SF entre las superficies de guiado FF1 y FF2 de la abertura vertical, en el sentido de la flecha doble DP. En el larguero de bastidor SH1, reproducido en el dibujo a la izquierda, se ha previsto en la superficie limitadora de la abertura vertical de bastidor SF una escotadura AS, en la que, verticalmente respecto a la superficie de guiado FF1, se ha aplicado una placa plana PL guiada de forma desplazable. Ésta presenta, en su lado vuelto hacia la colisa de cojinete LE y su superficie de contacto AF, la superficie de guiado FF1 subordinada a la misma y es impulsada por detrás por el émbolo de un conjunto émbolo-cilindro KZA, aplicado en el larguero de bastidor SH. Sobre la superficie de la placa PL, vuelta hacia la superficie de contacto AF de la colisa de cojinete LE, puede colocarse de forma no representada, una placa de desgaste, uno de cuyos lados forma entonces la superficie de guiado FF1.The drawing shows in schematic representation the partial view of a vertical opening of SF frame, formed on the frame beams SH1, SH2, of a rolling frame not otherwise shown, as seen in the direction of the axis of the cylinder. The bearing collet LE of the cylinder W is guided, with upward and downward movement, in the vertical opening of SF frame between the guiding surfaces FF1 and FF2 of the vertical opening, in the direction of the double DP arrow. In the frame beam SH1, reproduced in the drawing on the left, is provided on the limiting surface of the vertical opening of frame SF a recess AS, in which, vertically respect to the guiding surface FF1, a flat plate PL has been applied Guided in a scrollable way. This one presents, on its side turned towards the bearing collet LE and its contact surface AF, the Guided surface FF1 subordinated to it and is driven by behind by the piston of a piston-cylinder assembly KZA, applied to the frame member SH. On the surface of the PL plate, turned towards the contact surface AF of the colisa of bearing LE, can be placed not represented, a plate of wear, one of whose sides then forms the surface of guided FF1.
Con ayuda del conjunto émbolo-cilindro KZA puede desplazarse la placa PL, a través de dispositivos de control hidráulicos no representados, en la escotadura AS, a lo largo del recorrido de ajuste AW en contra de la colisa de cojinete LE. Con ello se generan las fuerzas de apriete FP precalculadas y las fuerzas de rozamiento FR, resultantes de éstas, entre las superficies de guiado FF1 y FF2 de la abertura vertical de bastidor SF y las superficies de apriete AF1 y AF2 de la colisa de cojinete LE.With the help of the set KZA piston-cylinder can move the PL plate, to through hydraulic control devices not shown, in the notch AS, along the AW adjustment path against of the bearing collet LE. This generates the forces of squeeze precalculated FP and friction forces FR, resulting therefrom, between the guiding surfaces FF1 and FF2 of the vertical opening of the SF frame and the clamping surfaces AF1 and AF2 of the bearing collet LE.
La placa PL puede utilizarse por el lado de accionamiento o el lado de manipulación en cilindros de apoyo, cilindros intermedios e incluso cilindros de trabajo de un bastidor de laminación.The PL plate can be used on the side of drive or handling side in support cylinders, intermediate cylinders and even one-frame work cylinders of lamination.
