Description

Máquina de doblamiento de tuberías que tiene una transmisión de movimiento mejorada a una matriz de doblamiento. Pipe bending machine that has an improved motion transmission to a bending die.

La presente invención se refiere a una máquina de doblamiento de tuberías que tiene una transmisión de movimiento mejorada a una matriz de doblamiento, de acuerdo con el preámbulo de la reivindicación 1 (véase, por ejemplo, el documento PJ-A-60231527). The present invention relates to a pipe bending machine having an improved motion transmission to a bending die, according to the preamble of claim 1 (see, for example, document PJ-A-60231527).

En las máquinas de doblamiento de tubería existentes, la máquina comprende un cuerpo y una cabeza. Alojado en el cuerpo, se encuentra un motor cuyo árbol de salida soporta una rueda de engranaje de accionamiento dispuesta en la cabeza de la máquina. La rueda de engranaje de accionamiento se acopla o engrana con una rueda de engranaje accionada que está conectada o unida rígidamente a una matriz de doblamiento de tuberías. Es evidente que cuanto mayor es el diámetro de las tuberías que se han de doblar, más grande es la potencia requerida por el motor y, también, las ruedas de engranaje de transmisión deben ser adecuadas para el par requerido. Un par requerido que aumenta necesita tamaños de la máquina incrementados y, como resultado de ello, también el coste de la máquina asciende. In existing pipe bending machines, the machine comprises a body and a head. Housed in the body, there is a motor whose output shaft supports a drive gear wheel arranged in the machine head. The drive gear wheel is coupled or geared with a driven gear wheel that is rigidly connected or joined to a pipe bending die. It is clear that the larger the diameter of the pipes to be bent, the greater the power required by the engine and, also, the transmission gear wheels must be suitable for the required torque. A required torque that increases requires increased machine sizes and, as a result, the cost of the machine also rises.

Las Patentes norteamericanas Nos. 3.302.505 y 5.709.144, a nombre de Shiokawa, se refieren, ambas, a una máquina de prensado o prensa caracterizada por ser de pequeño tamaño pero producir una alta presión. Entre las soluciones escogidas por ese inventor para alcanzar sus objetivos, se establecen disposiciones para que la potencia sea transmitida desde una rueda de engranaje de accionamiento a una rueda de engranaje accionada mediante la interposición de un par de ruedas de piñón locas entre dichas ruedas de engranaje. Con ello, tal como se dice en esas Patentes, “la fuerza transferida por la rotación se duplica, de tal modo que el diámetro de la rueda de engranaje puede se reducido a la mitad. Como resultado de ello, se hace posible reducir las medidas de la máquina colocando todos los engranajes en el bastidor, así como reducir el desgaste y el ruido de cada parte”. US Patents Nos. 3,302,505 and 5,709,144, in the name of Shiokawa, both refer to a press or press machine characterized by being small in size but producing high pressure. Among the solutions chosen by that inventor to achieve his objectives, provisions are set so that the power is transmitted from a drive gear wheel to a driven gear wheel by interposing a pair of idler gear wheels between said gear wheels. . Thus, as stated in those Patents, “the force transferred by the rotation doubles, so that the diameter of the gear wheel can be reduced by half. As a result, it is possible to reduce the machine measurements by placing all the gears in the frame, as well as reducing the wear and noise of each part. ”

De acuerdo con la presente invención, se ha concebido trasladar lo que se preconiza con referencia a una máquina de prensado o prensa, a otro tipo de máquina, tal como una dobladora de tuberías, adoptando la misma solución con el propósito de obtener ya sean tamaños reducidos, ya sea, alternativamente, un rendimiento mejorado de la máquina de doblamiento de tuberías. In accordance with the present invention, it has been conceived to transfer what is recommended with reference to a press or press machine, to another type of machine, such as a pipe bender, adopting the same solution in order to obtain either sizes reduced, either, alternatively, an improved performance of the pipe bending machine.

En este contexto, el problema técnico en la base de la presente invención consiste en proporcionar una máquina de doblamiento de tuberías que tiene una transmisión de movimiento mejorada a una matriz de doblamiento con el fin de superar las desventajas antes citadas referentes a la voluminosidad y a la baja potencia transmitida en el estado de la técnica. In this context, the technical problem at the base of the present invention is to provide a pipe bending machine that has an improved motion transmission to a bending matrix in order to overcome the aforementioned disadvantages regarding bulkyness and low power transmitted in the state of the art.

En particular, es un propósito de la presente invención proporcionar una máquina de doblamiento de tuberías que tenga una transmisión de movimiento mejorada a una matriz de doblamiento, de tal manera que la máquina de doblamiento de tuberías tenga ruedas de engranaje de tamaño reducido y conserve la misma potencia transmitida desde la rueda de engranaje de accionamiento a la rueda de engranaje accionada. In particular, it is a purpose of the present invention to provide a pipe bending machine that has an improved motion transmission to a bending die, such that the pipe bending machine has small gear wheels and retains the same power transmitted from the drive gear wheel to the driven gear wheel.

El propósito se consigue generalmente por medio de una máquina de doblamiento de tuberías que tiene una transmisión de movimiento mejorada a una matriz de doblamiento, de tal modo que la máquina comprende un cuerpo y una cabeza, de manera que existe un motor alojado en el cuerpo de la máquina, el cual tiene un árbol de salida que soporta una rueda de engranaje de accionamiento, la cual está situada en la cabeza de la máquina, y una rueda de engranaje accionada, que está conectada o unida a una matriz de doblamiento de tuberías que está situada en la misma cabeza de la máquina, en la cual un par de ruedas de engranaje intermedias se acoplan o engranan tanto en la rueda de engranaje de accionamiento como en la rueda de engranaje accionada. The purpose is generally achieved by means of a pipe bending machine that has an improved motion transmission to a bending matrix, such that the machine comprises a body and a head, so that there is a motor housed in the body. of the machine, which has an output shaft that supports a drive gear wheel, which is located at the head of the machine, and a driven gear wheel, which is connected or attached to a pipe bending matrix which is located on the same machine head, in which a pair of intermediate gear wheels are engaged or engaged both in the drive gear wheel and in the driven gear wheel.

Como puede observarse, el Solicitante ha desarrollado una denominada invención de traslación, trasponiendo un dispositivo de un campo técnico en el que dicho dispositivo ya es conocido, a otro en el que el dispositivo no ha sido aún empleado. As can be seen, the Applicant has developed a so-called translation invention, transposing a device from a technical field in which said device is already known, to another in which the device has not yet been used.

Características y ventajas adicionales de la presente invención se pondrán de manifiesto de forma más evidente por medio de una descripción esquemática de una realización de una máquina de doblamiento de tuberías que tiene una transmisión de movimiento mejorada a una matriz de doblamiento, tal y como se muestra en los dibujos que se acompañan, en los cuales: Additional features and advantages of the present invention will become apparent more clearly by means of a schematic description of an embodiment of a pipe bending machine having an improved motion transmission to a bending die, as shown. in the accompanying drawings, in which:

la Figura 1 es una vista axonométrica en corte, de la que se han eliminado algunas partes, de una máquina de doblamiento de tuberías de acuerdo con la invención; la Figura 2 es una vista en planta superior y en corte parcial de la máquina de doblamiento de tuberías ilustrada en la Figura 1, de la que se ha retirado la matriz de doblamiento; y la Figura 3 es una vista axonométrica general de la máquina de doblamiento de tuberías de acuerdo con la invención, con una tubería lista para ser doblada. Figure 1 is an axonometric sectional view, from which some parts have been removed, of a pipe bending machine according to the invention; Figure 2 is a top and partial sectional view of the pipe bending machine illustrated in Figure 1, from which the bending die has been removed; and Figure 3 is a general axonometric view of the pipe bending machine according to the invention, with a pipe ready to be bent.

En primer lugar, haciendo referencia a la vista axonométrica de la Figura 1, se indica en ella un cuerpo de máquina con la referencia 1 y una cabeza de máquina con la referencia 2. Convencionalmente, situado en el interior del cuerpo de la máquina, existe un motor 3, generalmente un motor eléctrico. Una rueda de engranaje de accionamiento 5 está enchavetada al árbol de salida 4 del motor 3. Situado en la cabeza 2 de la máquina, existe también una matriz de doblamiento 6 (que se muestra tan solo parcialmente) que permite que las tuberías sean dobladas de un modo conocido. La matriz de doblamiento 6 se hace rotar por un árbol 7 al que está enchavetada una rueda de engranaje accionada 8. De acuerdo con la presente invención, como se muestra mejor en la vista en planta superior de la máquina de doblamiento de tuberías de la Figura 2 (de la que se ha eliminado la matriz de doblamiento), unas ruedas de engranaje intermedias 9 y 10 se han interpuesto entre la rueda de engranaje de accionamiento 5 y la rueda de engranaje accionada 8. Las ruedas de engranaje intermedias 9 y 10 se acoplan o engranan al mismo tiempo tanto con la rueda de engranaje de accionamiento 5 como con la rueda de engranaje accionada 8. De esta manera, las ruedas de engranaje intermedias 9 y 10 transmiten, ambas, un movimiento de rotación desde la rueda de engranaje de accionamiento 5. Si la rueda de engranaje de accionamiento rota en un sentido, también la rueda de engranaje accionada 8 rota en el mismo sentido. First, referring to the axonometric view of Figure 1, there is indicated a machine body with the reference 1 and a machine head with the reference 2. Conventionally, located inside the machine body, there is a motor 3, generally an electric motor. A drive gear wheel 5 is keyed to the output shaft 4 of the motor 3. Located at the head 2 of the machine, there is also a bending die 6 (shown only partially) that allows the pipes to be bent from A known way. The bending die 6 is rotated by a shaft 7 to which a driven gear wheel 8 is keyed. In accordance with the present invention, as best shown in the top plan view of the pipe bending machine of the Figure 2 (from which the bending die has been removed), intermediate gear wheels 9 and 10 have interposed between the drive gear wheel 5 and the driven gear wheel 8. The intermediate gear wheels 9 and 10 are they both engage or engage both the drive gear wheel 5 and the driven gear wheel 8. In this way, the intermediate gear wheels 9 and 10 both transmit a rotational movement from the gear wheel of drive 5. If the drive gear wheel rotates in one direction, the driven gear wheel 8 also rotates in the same direction.

Gracias a la presente invención, para una misma potencia transmitida desde el motor 3 a la matriz de doblamiento 6, el tamaño de las ruedas de engranaje de la transmisión y, por tanto, de la cabeza 2 de la máquina y, en general, de la máquina de doblamiento de tuberías, puede ser reducido. Thanks to the present invention, for the same power transmitted from the motor 3 to the bending die 6, the size of the transmission gear wheels and, therefore, of the machine head 2 and, in general, of The pipe bending machine, can be reduced.

Con referencia a la Figura 3, se ha mostrado en ella una vista axonométrica general de la máquina de doblamiento de tuberías en la que se incorpora la presente invención. Se representa en ella una tubería T que se ha colocado entre la matriz de doblamiento 6 y la matriz de doblamiento 11 contraria o en oposición, lista para ser doblada. With reference to Figure 3, a general axonometric view of the pipe bending machine in which the present invention is incorporated is shown. It represents a pipe T that has been placed between the bending matrix 6 and the opposite or opposing bending matrix 11, ready to be bent.

Gracias a la presente invención, para tamaños de la máquina iguales a los de las máquinas precedentes que tienen un rendimiento reducido, se hace más fácil desarrollar un rendimiento de doblamiento mejorado, hasta el doble del presente. Thanks to the present invention, for machine sizes equal to those of the preceding machines having reduced performance, it becomes easier to develop an improved bending performance, up to double this.
