Description
Dispositivo para la fabricación de un cable trenzado.Device for the manufacture of a cable braided.
La invención se refiere a un dispositivo para la fabricación de un cable trenzado con dirección del golpe cambiante a partir de alambres individuales de sección transversal redonda y particularmente no redonda, con un cabezal plegador accionado con dirección de giro variable, con rodillos para cada alambre individual, cuyo perfil de rodillo se adapta a la sección transversal de cada alambre individual.The invention relates to a device for the fabrication of a twisted cable with changeable stroke direction from individual wires of round cross section and particularly non-round, with a folding head operated with variable turning direction, with rollers for each wire individual, whose roller profile adapts to the section cross section of each individual wire.
Los cables trenzados de este tipo, de tres o cuatro conductores sectoriales de cobre o de aluminio de gran sección transversal con un aislamiento plástico con dirección del golpe cambiante se usan, por ejemplo, en tendidos de alta tensión.Braided cables of this type, three or four large copper or aluminum sector conductors cross section with plastic insulation with direction of changing blow are used, for example, in high laying tension.
Se conocen dispositivos para trenzados con dirección del golpe cambiante para conductores redondos. El documento EP-A1-0582802 describe una máquina de trenzado con dirección del golpe cambiante para alambres de sección transversal redonda. Se compone de una guía de alimentación fija en un tensor y un cabezal plegador con movimiento pendular, con guías para cada alambre.Braided devices are known with Changing stroke direction for round conductors. He EP-A1-0582802 describes a braiding machine with changing punch direction for wires Round cross section. It consists of a guide of fixed feed on a tensioner and a folding head with movement pendular, with guides for each wire.
De los documentos DE-A-2855593 y DE-A-2637943 se conocen dispositivos genéricos, que también sirven para el trenzado de alambres individuales de sección transversal redonda. Para la solicitación del aislamiento de los alambres individuales durante el paso por el disco de trenzado, se han dispuesto rodillos de inversión en el disco de trenzado. Las superficies activas de los rodillos de inversión permiten una guía de los alambres individuales redondos en el disco de trenzado sin daños.Of the documents DE-A-2855593 and DE-A-2637943 known devices generic, which also serve for wire braiding Round cross section individual. For the solicitation of the isolation of the individual wires during the passage through the twisted disc, reversing rollers are arranged in the twisted disc The active surfaces of the rollers of inversion allow a guide of the individual round wires in the braided disc without damage.
Los alambres sectoriales, que no sean alambres redondos, por su forma de adaptarse al cable, deben ser retorcidos además una vez por golpe (rotación) sobre su eje (trenzado sin retrogiro). Esto significa que deben proporcionarse altos momentos de torsión sobre los alambres/conductores individuales (aplicados sobre sus ejes longitudinales).Sector wires, other than wires round, due to their way of adapting to the cable, they must be twisted also once per stroke (rotation) on its axis (braided without retrogiro). This means that high moments must be provided. of torsion on individual wires / conductors (applied on its longitudinal axes).
Si hay que retorcer los alambres sobre sus ejes, entonces deben sujetarse de forma resistente a la torsión al cabezal plegador. Es obvio para ello emplear guías y rodillos de guía adaptados a la sección transversal del alambre en arrastre de forma. No obstante, es poco probable que el aislamiento de plástico del conductor no se dañe, independientemente de la firmeza y tipo de conductor empleado (Al, Cu - trenzado macizo de un solo o de varios alambres), sobre todo porque la forma redonda de la sección transversal del conductor, con 90º ó 120º de ángulo de sector, ofrece poco "agarre" para una guía perfilada, debido a sus redondeces relativamente grandes en las aristas.If you have to twist the wires on their axes, then they must be fastened torsionally to the head beam. It is obvious to use guides and guide rollers adapted to the cross section of the drag wire of shape. However, plastic insulation is unlikely The driver is not damaged, regardless of the firmness and type of employed driver (Al, Cu - solid braided single or several wires), especially since the round shape of the section transverse of the conductor, with 90º or 120º of sector angle, offers little "grip" for a profiled guide, due to its relatively large roundnesses on the edges.
La presente invención tiene, por tanto, el objetivo de crear un dispositivo del tipo mencionado anteriormente, en el que la presión específica superficial en el retorcido de los alambres individuales sea mantenida pequeña.The present invention therefore has the aim of creating a device of the type mentioned above, in which the specific surface pressure in the twisting of the Individual wires are kept small.
Este objetivo se alcanza con un dispositivo con las características de la reivindicación 1.This goal is achieved with a device with the characteristics of claim 1.
En la invención, se disponen los rodillos de perfil que aplican la fuerza de torsión en el cabezal plegador en un arco tal que para el retorcido del conductor (cable y aislante) se ha fabricado un brazo de manivela con un radio de forma que la fuerza correspondiente del contorno se torna tan pequeña que el aislante de plástico del conductor no resulta dañado.In the invention, the rollers are arranged profile that apply the torsional force on the folding head in an arc such that for the twisting of the conductor (cable and insulator) a crank arm with a radius has been manufactured so that the corresponding contour force becomes so small that the Plastic conductor insulation is not damaged.
En las figuras está representado un ejemplo de realización de la invención. Se muestra:An example of embodiment of the invention. It shows:
Fig.1 una vista lateral de un cabezal plegador conforme a la invención con el casquillo de trenzado a continuación yFig. 1 a side view of a folding head according to the invention with the braiding sleeve below Y
Fig.2 un corte parcial a través del cabezal plegador.Fig. 2 a partial cut through the head beam.
Las Fig. 1 y Fig. 2 muestran por ejemplo un cabezal plegador 3 de este tipo, en el que no está representado el "tensor extendido" situado previamente en dirección de marcha 7 del alambre. El cabezal plegador 3 gira sobre rodamientos en los puntos de apoyo 10, 11, está accionado de forma oscilante por el motor 12 y la transmisión por correa 13. Los alambres individuales 1 con su aislante 2 llegan desde el "tensor" en la dirección de recorrido 7.Fig. 1 and Fig. 2 show for example a folding head 3 of this type, in which the "extended tensioner" previously located in the direction of travel 7 of the wire. The folding head 3 rotates on bearings in the support points 10, 11, is oscillatingly actuated by the engine 12 and belt drive 13. Individual wires 1 with its insulator 2 arrive from the "tensioner" in the direction of travel 7.
Para no dejar que la fuerza de torsión necesaria para el cableado de los alambres, ejercida sobre sus ejes longitudinales, ataque sobre las aristas redondeadas 14 de los alambres, se fuerza los alambres en forma de arco, hacia fuera, en contra de su posición recta natural, de modo que cada alambre 1 forma un brazo de palanca de radio R. La fuerza del contorno requerida Pu se reduce considerablemente, teniendo entonces todo el espesor de la sección transversal del alambre como línea de aplicación, de modo que la presión superficial se reduce lo suficiente para no dañar el aislante 2. El trenzado se forma en la boquilla de trenzado 9 y avanza en dirección 8 hacia un "tensor" de tipo conocido.To not let the necessary torque for wiring the wires, exerted on their axes longitudinal, attack on rounded edges 14 of the wires, arc-shaped wires are forced outward in against its natural straight position, so that each wire 1 forms a lever arm of radius R. The force of the contour required Pu is reduced considerably, then having all the thickness of the wire cross section as a line of application, so that the surface pressure is reduced so enough not to damage the insulator 2. The braid is formed in the braiding nozzle 9 and moving in direction 8 towards a "tensioner" of known type.
En la Fig. 1 representada se representa como ejemplo la guía en forma curva por medio de varios rodillos pequeños, lo que disminuye el tamaño del cabezal de cableado. Esto también se podría realizar con un único rodillo de mayor diámetro (análogo a la rigidez del elemento de trenzado).In the represented Fig. 1 it is represented as example the guide in curved form by means of several rollers small, which decreases the size of the wiring head. This It could also be done with a single roller with a larger diameter (analogous to the stiffness of the braiding element).
