Description

Sistema de flexión con poco rozamiento en una caja de laminación de varios cilindros.Flexion system with little friction in one Multi-cylinder rolling box.

La invención se refiere a un dispositivo para flexionar los cilindros en una caja de laminación de varios cilindros, con bloques de flexión fijados por el lado de entrada y de salida entre las piezas de montaje de cilindro y las ventanas de bastidor que pueden tratarse mediante medios de ajuste.The invention relates to a device for flex the cylinders in a multi-lamination box cylinders, with flex blocks fixed on the input side and output between cylinder mounting parts and windows frame that can be treated by means of adjustment.

Los dispositivos genéricos se usan para regular la planeidad de un producto de laminación como elemento de ajuste para flexionar cilindros de trabajo. El elemento de ajuste tiene aquí influencia directa en la geometría de rendija entre cilindros en la región de aristas de banda, en donde los cilindros de trabajo se flexionan positivamente alrededor de las aristas de los cilindros situados por encima y negativamente alrededor de las aristas del producto de laminación.Generic devices are used to regulate the flatness of a rolling product as an adjustment element to flex work cylinders. The setting item has here direct influence on the gap geometry between cylinders in the band edge region, where the work cylinders they flex positively around the edges of the cylinders located above and negatively around the edges of the rolling product.

De la solicitud de patente alemana 22 50 953 se conoce una caja de laminación con cilindros de trabajo y de apoyo y un dispositivo de flexión de cilindros, en la que las piezas de montaje de los cilindros de trabajo se guían entre bloques anclados en las ventanas de bastidor y, para su tratamiento para la corrección de abultamientos en los cilindros de trabajo, están unidas mediante unidades de émbolo-cilindro asociadas a los bloques, que pueden tratarse por ambos lados, siendo guiada en cada bloque una pieza de guiado inferior y otra superior de forma desplazable verticalmente, mientras que por el contrario la primera pieza de guiado aloja el cilindro y la otra pieza de guiado está unida al émbolo, y las piezas de guiado están unidas a las piezas de montaje, en unión positiva de forma, en dirección horizontal mediante guías horizontales que se prolongan en paralelo a los cilindros para el cambio de cilindros entre los bastidores. De este modo se pretende lograr que para la flexión de los cilindros sean necesarias dos unidades de émbolo-cilindro en cada lado.From the German patent application 22 50 953, know a rolling box with work and support cylinders and a cylinder bending device, in which the parts of Mounting work cylinders are guided between anchored blocks in the frame windows and, for treatment for correction of bulges in the work cylinders, are joined by piston-cylinder units associated to the blocks, which can be treated on both sides, being guided in each block a lower and a superior guide piece vertically scrollable, while on the contrary the first guide piece houses the cylinder and the other guide piece is attached to the plunger, and the guide pieces are attached to the Mounting parts, in positive shape connection, in direction horizontal by horizontal guides that extend in parallel to the cylinders for changing cylinders between the racks. From This mode is intended to achieve that for the flexion of the cylinders two piston-cylinder units are necessary in each side.

Este dispositivo ha demostrado su utilidad en la práctica. Sin embargo, existe el inconveniente de que los cilindros deben disponerse por el lado de accionamiento y manejo, así como por el lado de entrada y salida. Mediante este alojamiento móvil de cada lado se producen forzosamente elevadas fuerzas de rozamiento, que influyen además negativamente en la regulación de planeidad.This device has proven its usefulness in the practice. However, there is the disadvantage that the cylinders they must be arranged on the drive and operating side, as well as by the input and output side. Through this mobile hosting of each high friction forces are produced, which They also negatively influence the regulation of flatness.

La invención se ha impuesto la tarea de reducir las fuerzas de rozamiento en un sistema del género expuesto.The invention has set itself the task of reducing frictional forces in a system of the exposed gender.

Para resolver esta tarea se propone que a los bloques de flexión del primer bastidor de cilindros se asigne un cilindro de émbolo, y a los bloques de flexión del bastidor de cilindros opuesto un dispositivo de posicionamiento vertical.To solve this task, it is proposed that bending blocks of the first cylinder frame be assigned a piston cylinder, and to the bending blocks of the frame of Opposite cylinders a vertical positioning device.

Mediante el posicionamiento y el enclavamiento de los bloques de flexión por medio del dispositivo de posicionamiento vertical, con preferencia un engranaje elevador de husillo, puede generarse un punto de giro alrededor del cual puede bascular la pieza de montaje. Para aplicar la fuerza de flexión del lado de accionamiento y manejo en los bloques de flexión sólo se necesita de este modo en cada caso un cilindro.Through positioning and interlocking of the bending blocks by means of the device vertical positioning, preferably a lifting gear of spindle, a pivot point can be generated around which Tilt the mounting piece. To apply the flexural force of the drive and drive side on the bending blocks only In this case, you need a cylinder.

Por medio de que en la caja de laminación sólo se usan ya dos cilindros para aplicar la fuerza de flexión en los bloques de flexión, puede reducirse considerablemente la fuerza de rozamiento.By means of the lamination box only two cylinders are already used to apply the bending force on the bending blocks, the force of friction.

Mediante el engranaje elevador de husillo puede compensarse también el margen de esmerilado de los cilindros.Using the spindle lift gear you can also compensate the grinding margin of the cylinders.

El dispositivo conforme a la invención puede usarse también para la flexión de cilindros intermedios en una caja de seis cilindros. También puede pensarse en un uso en cajas de laminación reversibles.The device according to the invention can also be used for flexing intermediate cylinders in a box of six cylinders. You can also think of a use in boxes of reversible lamination.

En las reivindicaciones subordinadas se hacen patentes otras configuraciones ventajosas de la invención.In the subordinate claims are made patents other advantageous configurations of the invention.

En el dibujo se ha representado un ejemplo de ejecución de la invención.An example of Execution of the invention.
