Abstract

L'invention porte sur un dispositif de découpage au gaz d'un grand trou de tube non orthogonal sur un cylindre de réservoir à pression. Le dispositif est disposé sur une machine de perçage et de fraisage (9). Le dispositif comprend un gabarit de raccordement de trou (7) fixé sur une broche de perçage de la machine de perçage et de fraisage, un tube denté (5) relié au gabarit de raccordement de trou, un chalumeau de coupe (3) relié au tube denté, etc. Un premier dispositif de réglage (4) est apte à régler la course verticale du chalumeau de coupe. Un deuxième dispositif de réglage (6) est apte à régler la longueur du gabarit de raccordement de trou. Le dispositif est simple et fiable, il a de faibles coûts de fabrication, supprime la nécessité de compiler un programme de processus complexe de la machine de perçage et de fraisage, il demande seulement à suivre un tracé circulaire, il a une haute vitesse de découpage au chalumeau, il respecte les spécifications de produit qui satisfont entièrement la qualité du processus, et il permet d'ouvrir des trous pour recevoir de gros tubes à différents angles grâce au réglage de l'angle entre le cylindre et la broche de perçage, ce qui est simple et commode.
