Description
Prensa radial para el ajuste de mangueras flexibles.Radial press for hose adjustment flexible
La presente solicitud se refiere a una prensa radial para el ajuste de mangueras flexibles.This application refers to a press radial for the adjustment of flexible hoses.
Las prensas radiales para la deformación y mecanizado de artículos con superficies externas circulares o poligonales, en especial para el ajuste de mangueras flexibles, son ya bien conocidas. Estas prensas normalmente tienen dos bloques, o correderas, que se mueven de forma radial el uno hacia el otro accionados por componentes de accionamiento relativo, provocando que el acercamiento/alejamiento de una serie de superficies en ángulos rectos entre sí interrumpa dichos bloques y la posterior apertura/cierre de una serie de abrazaderas situadas y guiadas entre estas superficies. En concreto, la Patente EP-0-539-787 describe una prensa radial en la que:Radial presses for deformation and machining of items with circular external surfaces or Polygonal, especially for the adjustment of flexible hoses, are already well known. These presses usually have two blocks, or slides, which move radially towards each other driven by relative drive components, causing that the approach / distance of a series of surfaces in right angles to each other interrupt those blocks and the subsequent opening / closing a series of clamps located and guided between these surfaces. Specifically, the Patent EP-0-539-787 describes a radio press in which:
- un bloque (en movimiento) es guiado hacia el otro bloque (fijo) por medio de vástagos de acoplamiento;- a block (in motion) is guided to the another block (fixed) by means of coupling rods;
- los vástagos son paralelos a la dirección del movimiento del bloque en movimiento, penetran en el bloque fijo exteriormente y desde lados opuestos a las superficies de soporte en ángulos rectos de las abrazaderas y están anclados firmemente al bloque en movimiento;- the stems are parallel to the direction of the movement of the moving block, penetrate the fixed block externally and from opposite sides to the support surfaces in right angles of the clamps and are firmly anchored to the moving block;
- los vástagos, además de estar conectados al bloque en movimiento, están conectados a un mecanismo de accionamiento, donde cada vástago tiene su propio accionamiento hidráulico; y donde- the stems, in addition to being connected to the moving block, are connected to a mechanism of drive, where each rod has its own drive hydraulic; and where
- los accionamientos hidráulicos se obtienen usando un diámetro del pistón y el cilindro suficiente para obtener la mínima distancia posible menor que la del eje de la prensa en ángulos rectos a la mesa de abrazaderas.- hydraulic drives are obtained using a diameter of the piston and the cylinder sufficient to obtain the minimum possible distance less than the axis of the press in right angles to the clamp table.
No obstante, el objeto de la presente invención es proporcionar el tipo de prensa radial citada anteriormente pero con un mecanismo de accionamiento con una nueva configuración, especialmente apto para dar alta estabilidad y solidez a la estructura de la prensa y que posibilita una fuerza de compresión alta con una baja potencia disponible del accionamiento hidráulico.However, the object of the present invention is to provide the type of radial press mentioned above but with a drive mechanism with a new configuration, especially suitable to give high stability and solidity to the structure of the press and that allows a compression force high with low power available from the drive hydraulic.
El objeto se consigue, de acuerdo con la invención, usando una prensa radial según la reivindicación 1 que sigue.The object is achieved, according to the invention, using a radial press according to claim 1 which follow.
Se describirán ahora los detalles de la invención a continuación haciendo referencia al dibujo indicativo y no limitativo adjunto, donde la única figura muestra un diagrama transversal parcial de la prensa.The details of the invention below with reference to the indicative drawing and no limitation attached, where the only figure shows a diagram partial transverse of the press.
La prensa radial bajo examen consiste en un bloque inferior 10 situado en una plataforma 11, cuya parte superior cierra un armazón 12, y un bloque superior 13 situado sobre la misma y frente al bloque inferior 10 y que se mueve verticalmente en relación con este último.The radio press under review consists of a lower block 10 located on a platform 11, whose upper part close a frame 12, and an upper block 13 located on the same and in front of the lower block 10 and that moves vertically in relationship with the latter.
Cada uno de los lados enfrentados de los dos bloques 10, 13 tiene un par de superficies 14, 15 inclinadas y en ángulo recto la una de la otra, separadas por una superficie horizontal 16. Los ejes simétricos de las superficies 14, 15 y 16 se cruzan con el eje horizontal A de la prensa. Como es sabido, cuatro cuerpos externos 17 se apoyan en estas superficies 14-16, cada uno de ellos sosteniendo una abrazadera 18, y las superficies laterales 17' de estos cuerpos se usan para sostener y guiar a otros cuerpos internos 19 también equipados con abrazaderas 18. Los cuerpos 17 y 19 están dispuestos y configurados de tal forma que las superficies de las abrazaderas orientadas hacia el eje A sean equidistantes al mismo. El movimiento del bloque superior 13 hacia el inferior 10 causa el acercamiento radial a la misma velocidad de los cuerpos 17 y 19 y, por consiguiente, de todas las abrazaderas 18.Each of the two sides facing each other blocks 10, 13 have a pair of inclined surfaces 14, 15 and in right angle to each other, separated by a surface horizontal 16. The symmetric axes of surfaces 14, 15 and 16 they intersect with the horizontal axis A of the press. As is known, four external bodies 17 rely on these surfaces 14-16, each of them holding a clamp 18, and the lateral surfaces 17 'of these bodies are used for sustain and guide other internal bodies 19 also equipped with clamps 18. The bodies 17 and 19 are arranged and configured such that the surfaces of the clamps oriented towards axis A be equidistant to it. Block movement upper 13 towards lower 10 causes radial approach to the same speed of bodies 17 and 19 and, consequently, of all the clamps 18.
El bloque superior 13 se mueve mediante un sistema 20 de accionamiento hidráulico situado dentro del armazón 12, debajo de la plataforma 11, y es guiado hacia el bloque inferior 10 por medio de un par de columnas 21. La parte superior de estas columnas está anclada al bloque superior 13 por pernos 22, que pasan exteriormente a través del bloque inferior 10 y en lados opuestos de las superficies 14 y 15 y penetran en el armazón 12 a través de la plataforma 11 para fijarse al sistema 20 de accionamiento hidráulico.The upper block 13 is moved by a hydraulic drive system 20 located inside the frame 12, under platform 11, and is guided to the lower block 10 by means of a couple of columns 21. The top of these columns is anchored to the upper block 13 by bolts 22, which pass outwardly through the lower block 10 and on opposite sides of surfaces 14 and 15 and penetrate frame 12 through the platform 11 to be fixed to the drive system 20 hydraulic.
Estos sistemas 20 de accionamiento se componen
de una unidad 23 de accionamiento para cerrar la prensa bajo
presión alrededor del artículo a mecanizar y un cilindro 24 para el
acercamiento/retracción rápida del bloque superior 13 con respecto
al bloque inferior 10. De acuerdo con la invención, la unidad 23 de
accionamiento se compone de un solo cilindro provisto para albergar
un pistón al que están enchavetadas, en posiciones opuestas en
relación con el centro, las dos columnas 21. En otras palabras,
estas columnas forman los ejes de un único pistón
25.These drive systems 20 consist of a drive unit 23 for closing the press under pressure around the article to be machined and a cylinder 24 for fast approaching / retracting the upper block 13 with respect to the lower block 10. According to the invention , the drive unit 23 is comprised of a single cylinder provided to house a piston to which the two columns 21 are in opposite positions in relation to the center. In other words, these columns form the axes of a single piston.
25.
Además, las columnas guía 21 están fijadas, por ejemplo con tornillos, a un larguero 26 de refuerzo, situada debajo del pistón 25 y siendo dicho larguero continuo con respecto al cilindro 24 de acercamiento/retracción rápida. Este cilindro 24 tiene un pistón 27 conectado al bloque inferior mediante su eje 27' de tal forma que, cuando el aceite bajo presión entra en la cámara del cilindro 24, causa un movimiento rápido de dicho cilindro y, como consecuencia, del larguero 26 de refuerzo, de las columnas guía 21 y del bloque superior 13, en relación con el bloque inferior 10 (véase la línea de puntos en la figura).In addition, the guide columns 21 are fixed, by example with screws, to a reinforcing beam 26, located below of the piston 25 and said stringer being continuous with respect to the Rapid approach / retraction cylinder 24. This cylinder 24 it has a piston 27 connected to the lower block by its axis 27 ' such that when oil under pressure enters the chamber of cylinder 24, causes rapid movement of said cylinder and, as a consequence, of the reinforcing beam 26, of the guide columns 21 and of the upper block 13, in relation to the lower block 10 (see the dotted line in the figure).
Para el beneficio del sistema, el pistón 25 de accionamiento tiene un anillo reductor central 28, que permite que la sección de empuje del pistón se reduzca notablemente, permitiendo así el uso de una bomba de baja capacidad.For the benefit of the system, the piston 25 of drive has a central reduction ring 28, which allows the piston thrust section is significantly reduced, allowing thus the use of a low capacity pump.
Entre la unidad 23 de accionamiento, con su pistón 25 y su anillo 28 de reducción relacionados, y la plataforma 11, hay una placa 29 a través de la cual pasan las columnas guía 21 y el eje 27' del cilindro y dicha placa 29 evita que se deforme el bloque inferior 10 durante la fase de presión al contraponerse al mismo.Between the drive unit 23, with its related piston 25 and its reduction ring 28, and the platform 11, there is a plate 29 through which guide columns 21 pass and the axle 27 'of the cylinder and said plate 29 prevents the deformation of the lower block 10 during the pressure phase when opposing the same.
Por último, la presa se completa con un grupo motor 30 que acciona una bomba 31 usada para alimentar a las unidades de accionamiento hidráulico. Gracias a lo compacto de los bloques 10, 13 de la prensa y de las propias unidades 20 de accionamiento, el grupo motor 30 y la bomba 31 pueden albergarse totalmente dentro del armazón 12 de la prensa, seguros y protegidos de maniobras no autorizadas.Finally, the dam is completed with a group motor 30 that drives a pump 31 used to feed the hydraulic drive units. Thanks to the compactness of the blocks 10, 13 of the press and of units 20 of drive, motor group 30 and pump 31 can be accommodated fully within the framework 12 of the press, safe and secure of unauthorized maneuvers.
La función operativa detallada de la prensa es bien conocida en sí misma y no requiere mayor descripción. Debe destacarse el hecho de que el anclaje de las dos columnas guía a un solo pistón hace a la prensa especialmente estable y sólida, ya que evita el desnivel entre las dos columnas con la posterior deformación de los dos bloques. El efecto de reacción de la placa 29 contra las fuerzas de compresión que actúan en el bloque inferior 10 y en la plataforma 11 también es digno de mención.The detailed operational function of the press is well known in itself and does not require further description. Should highlight the fact that the anchoring of the two columns guides a single piston makes the press especially stable and solid, since that avoids the unevenness between the two columns with the subsequent deformation of the two blocks. The reaction effect of the plate 29 against compression forces acting in the lower block 10 and on platform 11 it is also noteworthy.
