Abstract

L'invention concerne un dispositif de formage (90) ainsi qu'un procédé de formage d'une pièce de départ (38) en un corps creux (50), qui présente une partie de col (46) et une portion d'épaulement (70) s'évasant en partant de la partie de col dans son prolongement. Le corps creux (50) sert par exemple à fabriquer des bombes aérosols ou des canettes de boisson en un matériau métallique, par exemple en aluminium ou en fer blanc. Au cours d'une première étape de formage U1, une pièce de départ (38) en forme de pot est d'abord façonnée pour former, à une extrémité axiale, la partie de col fermée d'un côté et prenant la forme d'un cylindre creux, ainsi qu'une paroi intermédiaire (47) entourant coaxialement la partie de col, les deux étant entourées coaxialement par une paroi en forme de cylindre creux (39). Au cours d'une deuxième étape de formage, la partie de col (46) est décalée par rapport à la paroi en forme de cylindre creux (39) pour que la paroi intermédiaire soit façonnée en une portion d'épaulement (70).
