Abstract

La présente invention concerne un dispositif servant à la réalisation d'une courbe sinusoïdale de pente quelconque. Ce dispositif comprend une manivelle 31 entraînée par un arbre 30 qui déplace à l'aide d'une pièce de glissement 34 un premier guidage 35 couplé à un second guidage 50 pour que ces derniers exécutent le même mouvement. Un troisième guidage 51 est monté pivotant autour d'un axe 52 et coupe à moins de 90 degrés le second guidage 50. Un pièce de glissement 54 à l'intersection du second et du troisième guidage se déplace le long du deuxième et du troisième guidage et est relié à des éléments de transmission de mouvements 60 à 65 agissant sur une tige de poussée 66 portant l'instrument servant à tracer la courbe sur la plaque de tôle. Ce dispositif est utilisé dans les machines servant à former des coudes de tube à partir de segments de tube.
