Abstract

La présente invention concerne un poinçon d'expansion de tuyau et, plus particulièrement, un poinçon d'expansion de tuyau pour perceuse qui permet d'élargir un tuyau en le frappant au moyen d'un foret d'ancrage ou d'un foret rechargeable. Selon un mode de réalisation de la présente invention, le poinçon d'expansion de tuyau comprend : une bille d'expansion dans laquelle sont formées une ou plusieurs portions (ci-après appelées « parties d'expansion ») de diamètre externe supérieur à un diamètre interne d'un tuyau à élargir ; et un support formé d'un seul tenant avec la bille d'expansion et couplé de manière fixe à une perceuse de sorte que le tuyau puisse être élargi au moyen du foret, le diamètre externe d'une partie d'introduction d'une portion d'extrémité de la bille d'expansion étant formé pour être plus petit que le diamètre interne du tuyau, une première marche conique étant formée entre la partie d'introduction et la partie d'expansion, ladite première marche conique étant polie et comportant sur elle une ou plusieurs surfaces polies.
