Abstract

Un appareil d'hydroformage destiné à l'hydroformage d'une pièce de fabrication est décrit. L'appareil comprend un emporte-pièce comportant la cavité du moule, de même qu'un sous- ensemble de bague extérieure. Le sous-ensemble, mobile par rapport à l'emporte-pièce, comporte une bague à laquelle sont rattachés un premier segment de came ou plus, un second segment de came ou plus, ainsi que des coins placés entre les premier et deuxième segments de cames. Le coin peut être déplacé d'une position de sortie, dans laquelle le second segment de came est poussé en position ouverte d'embrayage par rapport aux surfaces externes lorsque le sous- ensemble est le plus près de l'emporte-pièce, à une position rétractée, dans laquelle le second segment de came est activé en position fermée. La surface inférieure du second segment de came est formée de manière à engrener les surfaces extérieures.
