Description
HERRAMIENTA CORTATUBOS CON DISPOSITIVO DE AJUSTE CUTTUBE TOOL WITH ADJUSTMENT DEVICE
La presente invención se refiere a una herram ienta cortatubos que presenta un dispositivo de ajuste que la perm ite adaptarse a diferentes diámetros de tubos a cortar y mejora el apoyo de tales tubos durante el proceso de corte. The present invention relates to a pipe cutter tool that has an adjustment device that allows it to adapt to different diameters of tubes to be cut and improves the support of such tubes during the cutting process.
La herramienta cortatubos de la presente invención es del tipo de las constitu i das en base a u n cuerpo conformado según dos elementos diferenciados. El primero de ellos, a modo de cabezal arqueado, determina una concavidad donde se incorporan al m enos dos rodillos interiores y es susceptible de alojar transversalmente el tubo a cortar, constituyendo los rodillos el medio de apoyo del tubo. El segundo elemento, dispuesto en continuidad con el primero, incluye un husillo que incorpora, en su extremo anterior enfrentado al cabezal, una cuchilla circular de corte, mientras que, en su extremo posterior, está vinculado a un pomo de accionamiento que permite desplazar axialmente dicho husillo y, con él, la cuchilla circular de corte, hasta que ésta entra en contacto con el tubo transversalmente, de forma que el tubo queda aprisionado entre la cuchilla circular de corte y los rodillos de apoyo diametralmente opuestos. Con este tipo de cortatubos, el corte se produce por el giro relativo de la herramienta cortatubos alrededor del tubo. The pipe cutter tool of the present invention is of the type constituted on the basis of a body formed according to two distinct elements. The first of them, as an arched head, determines a concavity where two inner rollers are incorporated at least and is capable of transversely accommodating the tube to be cut, the rollers being the support means of the tube. The second element, arranged in continuity with the first, includes a spindle that incorporates, at its front end facing the head, a circular cutting blade, while, at its rear end, it is linked to a drive knob that allows axial displacement said spindle and, with it, the circular cutting blade, until it comes into contact with the tube transversely, so that the tube is trapped between the circular cutting blade and the diametrically opposed support rollers. With this type of pipe cutter, the cut is produced by the relative rotation of the pipe cutter tool around the tube.
Por ej em p lo en los docum entos E S 1 033268 U, EP2468440 A1 , EP1 195216 B1 o US2012017377 se describen cortatubos correspondientes con esta configuración. For example, in the documents E S 1 033268 U, EP2468440 A1, EP1 195216 B1 or US2012017377 corresponding pipe cutters with this configuration are described.
Así, a modo ilustrativo, en la EP1 195216 B1 se propone un cortador de tubos del tipo citado anteriormente, esto es comprendiendo un alojamiento con una cuna para sostener el tubo, un cabezal de corte con una base y un brazo vertical de corte, dicha base y alojamiento provistos de elementos de guía longitudinales que interaccionan para permitir el movimiento deslizante lineal de la base en dicho alojamiento, una rueda de corte transportada por dicho brazo en un árbol para el giro alrededor del eje de dicho árbol, medios para desviar
dicha rueda de corte hacia la cuna y un árbol roscado que arrastra dicha base del cabezal de corte a lo largo de dichos elementos de guía hacia la cuna a una posición de corte después de que el tubo es sostenido en dicha cuna para flexionar dichos medios de desviación y forzar dicha rueda de corte contra dicho tubo preparatorio al giro de dicho cortador alrededor de dicho tubo, siendo la rueda de corte y el árbol móviles con relación a la base del cabezal de corte en la dirección lineal entre una primera posición, en la que están en una condición avanzada con relación a dicha base del cabezal de corte en dirección hacia la cuna, y una segunda posición en la que están en una condición desplazada hacia atrás con relación a dicha primera posición y dicha base del cabezal de corte en una dirección alejada de dicha cuna, disponiéndose los medios de desviación en el cabezal de corte. Thus, by way of illustration, in EP1 195216 B1 a tube cutter of the type mentioned above is proposed, this is comprising a housing with a cradle for holding the tube, a cutting head with a base and a vertical cutting arm, said base and housing provided with longitudinal guide elements that interact to allow linear sliding movement of the base in said housing, a cutting wheel transported by said arm in a tree for rotation around the axis of said tree, means for deflecting said cutting wheel towards the cradle and a threaded shaft that drives said base of the cutting head along said guide elements towards the cradle to a cutting position after the tube is held in said cradle to flex said means of deflecting and forcing said cutting wheel against said preparatory tube to the rotation of said cutter around said tube, the cutting wheel and the shaft moving relative to the base of the cutting head in the linear direction between a first position, in the which are in an advanced condition in relation to said base of the cutting head in the direction towards the cradle, and a second position in which they are in a condition displaced backward in relation to said first position and said base of the cutting head in a direction away from said cradle, the deflection means being arranged in the cutting head.
Con los cortatubos del tipo descrito y bien conocidos en el estado de la técnica actual, es necesario incrementar, según avanza el proceso de corte, la presión de la cuchilla circular sobre el tubo mediante la actuación sobre el pomo y, correspondientemente sobre el husillo. Sin embargo, para el corte de tubos gruesos de diámetros próximos a los límites de capacidad del cortatubo, al final del proceso de corte se presenta el problema de que el tubo deja de apoyar sobre todos los rodillos del cabezal arqueado, sustituyéndose este apoyo, con respecto a al menos uno de los rodillos, por otro sobre la propia pared interior del cabezal arqueado. With the cutters of the type described and well known in the state of the art, it is necessary to increase, as the cutting process progresses, the pressure of the circular blade on the tube by acting on the knob and, correspondingly on the spindle. However, for the cutting of thick tubes with diameters close to the capacity limits of the pipe cutter, at the end of the cutting process, the problem arises that the tube stops resting on all the rollers of the arched head, replacing this support, with with respect to at least one of the rollers, on the other on the inner wall of the arched head itself.
Este desajuste del tubo con respecto al cabezal arqueado provoca que la cuchilla circular no sea capaz de mantener el centro de corte con respecto al tubo, esto es el eje de corte se desplaza hacia el interior, generándose una fuerza excéntrica debida al momento de giro que hace que el final del proceso de corte implique una mayor fuerza de accionamiento y se obtenga un corte poco limpio. This mismatch of the tube with respect to the arcuate head causes the circular blade to not be able to maintain the cutting center with respect to the tube, that is the cutting axis moves inwards, generating an eccentric force due to the moment of rotation that It causes the end of the cutting process to imply greater driving force and an unclean cut.
Por otra parte, cuando las paredes del tubo son relativamente delgadas, la presión generada sobre el mismo hace que éste se deforme y pase a adoptar una sección elipsoide en vez de circular, lo que provoca que el recorrido del cortatubos alrededor del tubo durante el proceso de corte no siga una trayectoria
circular sino esencialmente elíptica. Debido a este efecto, la penetración del filo de la cuchilla en la pared del tubo no es siempre igual a lo largo de toda la circunferencia del tubo. Así, en algunos tramos la cuchil la lo atraviesa completamente, mientras que en otros tramos no lo hace, lo que se traduce en la imposibilidad de seccionar completamente el tubo. Para conseguir el corte completo es entonces necesario apl icar mayor presión a la cuch i l la, generándose nuevamente un efecto excéntrico, que si bien permite cortar el tubo, lo hace de forma muy violenta. On the other hand, when the walls of the tube are relatively thin, the pressure generated on it causes it to deform and go on to adopt an ellipsoid section instead of circulating, which causes the path of the pipe cutter around the tube during the process cutting do not follow a path circular but essentially elliptical. Due to this effect, the penetration of the blade edge into the tube wall is not always the same throughout the entire circumference of the tube. Thus, in some sections the knife goes through it completely, while in other sections it does not, which translates into the inability to completely section the tube. To achieve the complete cut it is then necessary to apply greater pressure to the knife, again generating an eccentric effect, which although it allows the tube to be cut, it does so very violently.
La presente invención proporciona una herramienta cortatubos del tipo citado que permite evitar las desventajas indicadas anteriormente asegurando la correcta adaptación al diámetro del tubo y su apoyo durante el proceso de corte. The present invention provides a pipe cutter tool of the aforementioned type that allows to avoid the disadvantages indicated above ensuring the correct adaptation to the diameter of the tube and its support during the cutting process.
Así, un objeto de la invención es un cortatubos que incorpora, en el interior del cabezal arqueado del mismo, entre los rodillos de apoyo y la cuchilla de corte, un dispositivo de ajuste, el cual consiste esencialmente en un disco guía paralelo a los rodillos de apoyo susceptible de girar alrededor de un eje transversal y q u e a s u v e z es desplazable manualmente de forma correspondiente al diámetro del tubo a cortar. Thus, an object of the invention is a pipe cutter that incorporates, within the arcuate head thereof, between the support rollers and the cutting blade, an adjustment device, which consists essentially of a guide disk parallel to the rollers of support capable of rotating around a transverse axis and which is probably manually movable corresponding to the diameter of the tube to be cut.
El dispositivo de ajuste permite optimizar el corte de una manera fácil, rápida e intuitiva, modificando la posición del disco guía manualmente a las diferentes posiciones en correspondencia con los diferentes diámetros de los tubos con el fin de optimizar el proceso de corte, de forma que éstos se mantienen en contacto o esencialmente en contacto con los rodillos de apoyo durante todo el proceso de corte, permitiendo que éste se lleve a cabo sin que el eje de corte se desplace ni se produzcan deformaciones del tubo. A continuación se explica detalladamente el objeto de la invención en base a una realización de la misma y con referencia a las figuras adjuntas, en las cuales: The adjustment device allows to optimize the cutting in an easy, fast and intuitive way, by modifying the position of the guide disc manually to the different positions in correspondence with the different diameters of the tubes in order to optimize the cutting process, so that these are kept in contact or essentially in contact with the support rollers during the entire cutting process, allowing it to be carried out without the cutting axis moving or deformation of the tube. The object of the invention is explained in detail below based on an embodiment thereof and with reference to the attached figures, in which:

Aunque en las figuras se muestra una realización del cortatubos de la invención presentando dos rodillos de apoyo, el cortatubos puede incluir cualquier número adecuado de rodillos de apoyo, y permite su aplicación para cualquier diámetro de tubo a cortar. Although an embodiment of the pipe cutter of the invention is shown in the figures by presenting two support rollers, the pipe cutter can include any suitable number of support rollers, and allows its application for any diameter of pipe to be cut.
Con referencia a la realización mostrada en la Fig. 1 , la herramienta cortatubos de la presente invención es del tipo de las constituidas en base a un cuerpo conformado según dos elementos diferenciados (1 , 4). El primero de ellos, a modo de cabezal arqueado (1 ), determina una concavidad donde se incorporan al menos dos rodillos de apoyo interiores (2) y es susceptible de alojar transversalmente el tubo a cortar (3). El segundo elemento (4), dispuesto en continuidad con el primero, incluye un husillo (5) que incorpora, en su extremo anterior enfrentado al cabezal, una cuchilla circular de corte (6), m ientras que, en su extrem o posterior, está vincu lado a un pom o de accionamiento (7) que permite desplazar axialmente dicho husillo (5) y, con él, la cuchil la circular de corte, hasta que ésta entra en contacto con el tubo transversalmente, de forma que el tubo queda aprisionado entre la cuchilla circular de corte y los rodillos de apoyo diametralmente opuestos. El cortatubos de la invención incorpora, en el interior del cabezal arqueado (1 ), entre los rodillos de apoyo (2) y la cuchilla de corte (6), un dispositivo de ajuste (8). With reference to the embodiment shown in Fig. 1, the pipe cutter tool of the present invention is of the type constituted on the basis of a body formed according to two differentiated elements (1, 4). The first one, as an arched head (1), determines a concavity where at least two inner support rollers (2) are incorporated and is capable of transversely accommodating the tube to be cut (3). The second element (4), arranged in continuity with the first, includes a spindle (5) that incorporates, at its front end facing the head, a circular cutting blade (6), while, at its end or rear, It is connected to a drive knob (7) that allows said spindle (5) to be axially displaced and, with it, the circular cutting knife, until it comes into contact with the tube transversely, so that the tube is trapped between the circular cutting blade and the diametrically opposite support rollers. The pipe cutter of the invention incorporates, within the arc head (1), between the support rollers (2) and the cutting blade (6), an adjustment device (8).
Tal como se observa en la Fig. 2 y más en detalle en la Fig. 3, este dispositivo de ajuste (8) consiste esencialmente en un disco guía (9) dispuesto en paralelo a los rodillos de apoyo (2) y que gira alrededor de un eje de disco
transversal (10) que lo atraviesa por su centro. El eje de disco (10) se une transversalmente a un brazo superior (11) y otro inferior (12) de forma que el disco guía (9) se mantiene en una conformación tipo sándwich entre ambos brazos (11, 12). Estos brazos transversales (11, 12) tienen una longitud mayor que el radio del disco guía (9) y ambos se unen, por su extremo opuesto, a un vástago correspondiente (13), el cual, a su vez, permite fijar el conjunto del dispositivo de ajuste (8) con libertad de desplazamiento a la herramienta cortatubos en una disposición entre los rodillos de apoyo (2) y la cuchilla de corte (6). El vástago (13) constituye, por tanto, el eje de giro del dispositivo de ajuste (8). As seen in Fig. 2 and more in detail in Fig. 3, this adjustment device (8) consists essentially of a guide disk (9) arranged parallel to the support rollers (2) and which rotates around of a disk shaft transverse (10) that crosses it through its center. The disk shaft (10) is attached transversely to an upper arm (11) and a lower one (12) so that the guide disk (9) is maintained in a sandwich-like conformation between both arms (11, 12). These transverse arms (11, 12) have a length greater than the radius of the guide disc (9) and both are joined, at their opposite end, to a corresponding rod (13), which, in turn, allows the assembly to be fixed of the adjusting device (8) with freedom of movement to the pipe cutter tool in an arrangement between the support rollers (2) and the cutting blade (6). The rod (13) therefore constitutes the axis of rotation of the adjustment device (8).
Perpendicularmente a los brazos transversales (11, 12) y orientados hacia la zona exterior del disco, se disponen sendos posicionadores superior (14) e inferior (15) respectivamente, cuya longitud se prolonga perpendicularmente de forma que quedan accesibles al usuario por ambos lados de la herramienta cortatubos. Perpendicularly to the transverse arms (11, 12) and oriented towards the outer area of the disc, there are arranged both upper (14) and lower (15) positioners respectively, whose length is extended perpendicularly so that they are accessible to the user on both sides of The pipe cutter tool.
Estos posicionadores (14, 15) permiten desplazar de forma manual, desde el exterior del cortatubos, el dispositivo de ajuste (8) a lo largo de sendos arcos de circunferencia alrededor del vástago (13), a modo de ranuras (16), lo cual, permite mantener fijo en una determinada posición adaptada al diámetro del tubo el disco guía (9) durante el proceso de corte del tubo, provocando que éste último se mantenga en contacto o esencialmente en contacto con los rodillos de apoyo (2) y el propio disco guía (9) durante todo el proceso. These positioners (14, 15) allow the adjustment device (8) to be moved manually from the outside of the pipe cutter along two circumferential arcs around the rod (13), by way of grooves (16), which, allows the guide disc (9) to be fixed in a certain position adapted to the diameter of the tube during the cutting process of the tube, causing the latter to remain in contact or essentially in contact with the support rollers (2) and the own guide disc (9) throughout the process.
Así, el dispositivo de ajuste es desplazable manualmente para adaptarse al diámetro correspondiente del tubo en la posición adecuada de los dos arcos ranura (16) definidos, anclándose en esta posición. Para fijar en cualesquiera de las posiciones el dispositivo de ajuste (8) en su desplazamiento a lo largo del arco ranura (16), tal como se observa en las Fig.1 y 4, los extremos del eje de disco (10) disponen perimetralmente de unas pestañas (no mostradas) orientadas hacia el exterior y susceptibles de engranar en escotaduras correspondientes dispuestas en la zona interior del arco ranura (16),
conformando así una fijación en ajuste de forma en la posición requerida para el conjunto del dispositivo de ajuste (8).
Thus, the adjustment device is manually movable to adapt to the corresponding diameter of the tube in the proper position of the two groove arches (16) defined, anchoring in this position. To fix the adjustment device (8) in any of its positions along its groove arc (16), as shown in Figs. 1 and 4, the ends of the disc shaft (10) are arranged perimetrically of tabs (not shown) facing outwards and capable of engaging in corresponding recesses arranged in the inner area of the groove arch (16), thus forming a fixation in form adjustment in the position required for the whole of the adjustment device (8).
