Description
Herramienta para máquina de doblar.Tool for folding machine.
La presente invención se refiere a una herramienta en máquinas de doblar tubos o perfiles (ver por ejemplo US-A-3 456 482).The present invention relates to a tool in pipe bending machines or profiles (see for example US-A-3 456 482).
Al doblar tubos mediante máquinas de doblar tubos, en las cuales los tubos son sujetados y son doblados por tracción en su extremidad libre, debido a aplastamientos de material pueden surgir arrugas en el lado interior del arco. Para evitarlo se utiliza una pieza de trabajo para reducir la formación de arrugas, el alisador de arrugas. Esta pieza puede tener diferentes configuraciones y ocasionalmente se llama también vaina alisadora o zapato alisador. En el lado interior de la zona de transformación viene apoyando el tubo en la dirección de la parte aun doblada. Al doblar, el tubo es dispuesto encima del alisador con gran fuerza de apriete, de modo que ello causa un desgaste considerable en el alisador. Para evitar el desgaste en el alisador, el mismo se protege con materiales adicionales como por ejemplo bronce de aluminio, bronce al berilio u otros materiales de bronce. No obstante, el alisador se gasta considerablemente y por este motivo tiene que ser cambiado con relativa frecuencia. Asimismo los ensayos con materias lubrificantes, como por ejemplo lubrificantes de molibdeno o nitruro de titanio respectivamente carbonitruro de titanio no han podido prolongar esencialmente la duración.When folding tubes using bending machines tubes, in which the tubes are held and folded by traction on its free limb due to material crushing wrinkles may arise on the inner side of the arch. To avoid it, I know use a workpiece to reduce wrinkle formation, The wrinkle straightener. This piece may have different configurations and occasionally it is also called smoothing sheath or smoothing shoe On the inner side of the transformation zone It is supporting the tube in the direction of the part still bent. To the bend, the tube is arranged on top of the straightener with great force of tighten, so that causes considerable wear on the smoothing To avoid wear on the straightener, it will be protects with additional materials such as bronze from aluminum, beryllium bronze or other bronze materials. Do not However, the straightener is spent considerably and for this reason It has to be changed relatively frequently. Also the trials with lubricating materials, such as lubricants of molybdenum or titanium nitride respectively carbonitride of Titanium could not essentially prolong the duration.
Al doblar, además se precisan mandriles, rodillos, ayudas de guía, matrices o carriles de guía que también se gastan bastante y por ello tienen que ser cambiados, aunque con menos frecuencia.When bending, mandrels are also required, rollers, guide aids, dies or guide rails that are also they spend a lot and therefore have to be changed, although with less frequency
El objeto de la presente invención es por ello proponer una posibilidad que permite prolongar la duración de las herramientas en las maquinas de doblar tubos y perfiles.The object of the present invention is therefore propose a possibility that allows the duration of tools in the machines for bending tubes and profiles.
De acuerdo con la invención, este objeto se logra mediante una herramienta, como un mandril, alisador o carriles de guía, con las características de la reivindicación 1.According to the invention, this object is achieved. using a tool, such as a mandrel, straightener or rails guide, with the features of claim 1.
Según la misma, la superficie de un alisador, un mandril, unos rodillos, ayudas de guía, matrices o carriles de guía, que tiene contacto con el tubo se reviste con una capa de molibdeno o de una aleación de molibdeno. Esta capa puede ser de menos de 0,1 mm y sin embargo causa una prolongación considerable de la duración. El molibdeno se aplica por ejemplo mediante un procedimiento de metalización con llama, de modo galvánico o mediante la impulsión por vapor.According to it, the surface of a straightener, a mandrel, rollers, guide aids, dies or guide rails, which has contact with the tube is coated with a layer of molybdenum or of a molybdenum alloy. This layer can be less than 0.1 mm and yet it causes a considerable prolongation of the duration. Molybdenum is applied, for example, by a process of flame metallization, galvanically or by impulsion By steam.
En la figura 1, a modo de ejemplo, se representa una máquina de doblar tubos con un mandril. En este caso, el doblado se efectúa mediante la tracción del tubo a través de una pieza tensora 2 por el giro de la matriz. Un carril 4 y un alisador 5 facilitan la guía exterior y el mandril 6 desplazable, dispuesto en el interior, impide la modificación del diámetro del tubo. Las superficies del carril 4, del alisador 5 y del mandril 6 que tienen contacto con el tubo están provistas de una capa de molibdeno o de una aleación de molibdeno.In figure 1, by way of example, it is represented a tube bending machine with a mandrel. In this case, the bending it is done by pulling the tube through a piece tensioner 2 by the rotation of the matrix. A lane 4 and a straightener 5 facilitate the outer guide and the movable mandrel 6, arranged in The interior prevents the modification of the tube diameter. The surfaces of rail 4, straightener 5 and mandrel 6 having contact with the tube are provided with a layer of molybdenum or a molybdenum alloy.
La figura 2 muestra a modo de ejemplo un alisador 5 en el cual la superficie 8 que tiene contacto con el tubo está provista de una capa protectora 7.Figure 2 shows by way of example a straightener 5 on which the surface 8 that has contact with the tube is provided with a protective layer 7.
