A method for manufacturing a hydroforming member includes the step of providing a blank (10). The blank (10) is defined by blank wall (16). The blank (10) is placed in a die assembly (14) having a die cavity (12) defined by a die surface (24). The blank (10) is expanded so that the blank wall (16) is forced against the die surface (24) to form the hydroformed member. A portion of the blank wall conforms against a wall-thinning element (26, 28) positioned along the die surface (24) to form a removable wall section (46, 50) in a portion of the blank wall (24). The removable wall section (46, 50) is then removed from the blank wall (16) to form an opening in the hydroformed member.

L'invention concerne un procédé de réalisation d'article hydroformé selon les étapes suivantes: fourniture d'une ébauche (10) définie par une paroi (16) d'ébauche. L'ébauche (10) est placée dans un ensemble matrice (14) à cavité de filière (12) définie par une surface (24) de filière. L'ébauche (10) subit une expansion qui contraint sa paroi (16) contre la surface (24) de filière pour la réalisation de l'article hydroformé. Une partie de ladite paroi se conforme à un élément amincisseur de paroi (26, 28) placé le long de la surface (24) de filière pour la formation d'une partie de paroi amovible (46, 50) dans une partie de cette paroi (16) d'ébauche. Ladite partie (46, 50) est ensuite retirée de la paroi (16) pour la formation d'une ouverture dans l'article hydroformé.
