The invention relates to a device (2,2') for internal high-pressure deformation of a blank (12) with the aid of a high-pressure fluid, comprising a tool (4,6) which is provided with a receiving area (8) for a blank, wherein the tool consists of at least one channel (22, 24, 26, 30, 32, 34) which leads into the receiving area and through which fluid remaining in the receiving area can be removed therefrom. The invention also relates to a method for operating a device for internal high-pressure deformation of a blank.
L'invention concerne un dispositif (2,2') destiné au façonnage par haute pression interne d'une ébauche (12) à l'aide d'un fluide haute pression. Ce dispositif comprend un moule (4, 6) présentant une empreinte (8) destinée à l'ébauche. Le moule a au moins un canal (22, 24, 26, 30, 32, 34) qui débouche dans l'empreinte et permet d'évacuer de l'empreinte le fluide résiduel restant dans l'empreinte. L'invention concerne également un procédé permettant de faire fonctionner un dispositif de façonnage par haute pression interne d'une ébauche.
