Title
(EN) APPARATUS FOR CUTTING AN OVAL HOLE IN THE WALL OF A PIPE
(FR) APPAREIL POUR DECOUPER UN TROU OVALE DANS LA PAROI D'UN TUYAU
Abstract
(EN)
The invention relates to an apparatus for cutting an oval hole in the wall of a pipe. The pipe secured to a baseplate (1) of the apparatus is cut for an oval hole by means of a tool (20) having its cutter head (24) rotated about its axis while it is driven along a circular path in relation to a carriage (2) of the apparatus. The carriage (2) is mounted on the baseplate (1) by way of linear runners (3). Adapted for rotation along with a drive pulley (4) of the tool (20) is a cogged wheel (10), which through the transmission of a cam lever (11) is adapted to drive a shaft (12) having its rotational motion transmitted on the one hand to drive a gear (22) and on the other hand to work the carriage (2) back and forth in relation to the baseplate (1), a round-trip displacement (2xa) being equal to a difference between the major axis and the minor axis of a desired ellipse.
(FR)
L'invention concerne un appareil permettant de découper un trou ovale dans la paroi d'un tuyau. Le tuyau fixé à une plaque de base (1) de l'appareil est découpé de manière à former un trou ovale à l'aide d'un outil (20) dont la tête porte-lames (24) tourne autour de son axe tandis qu'elle est entraînée le long d'un chemin circulaire relativement à un chariot (2) de l'appareil. Le chariot (2) est monté sur la plaque de base (1) à l'aide de rails linéaires (3). Conçue pour tourner avec une poulie d'entraînement (4) de l'outil (20) se trouve une roue dentée (10), laquelle par l'intermédiaire de la transmission d'un levier à came (11) est conçue pour entraîner un arbre (12) dont le mouvement de rotation est transmis d'une part pour entraîner une roue (22) et d'autre part pour actionner le chariot (2) en avant et en arrière relativement à la plaque de base (1), l'aller-retour (2xa) étant égal à une différence entre le grand axe et le petit axe d'une ellipse souhaitée.
