Abstract

L'invention concerne un système de transmission de tête de coupe destiné à être utilisé dans un appareil de découpage de tuyau, et comprenant : une glissière (310), une base de montage (320) et un composant de guidage (330). La glissière est disposée sur un côté du mécanisme de transmission qui transfère un tuyau à découper et est pourvue d'une position initiale. Le composant tête de coupe (500) est monté sur la base de montage. La base de montage est montée coulissante sur la glissière et est pourvue d'un mécanisme de verrouillage (340). Le mécanisme de verrouillage peut se verrouiller au moyen d'un bloc fixe disposé sur le mécanisme de transmission lorsque la base de montage est située au niveau de la position initiale. Le composant de guidage est utilisé pour guider la base de montage tandis que la base de montage est entraînée par le mécanisme de transmission en coulissant par rapport à la glissière, ce qui permet au composant tête de coupe de se déplacer vers le tuyau à découper et de terminer une action de découpe par rapport au tuyau à découper. L'invention concerne également l'appareil de découpage de tuyau pourvu du système de transmission de tête de coupe. L'appareil de découpage de tuyau et le système de transmission de tête de coupe, pourvus de la structure de transmission, permettent au composant tête de coupe de terminer automatiquement l'action de découpe et l'action de remise à zéro de la tête de coupe.
