The invention relates to a method and a device (1) for producing a peripherally closed hollow profiled element by means of fluidic internal high pressure. The inventive device comprises an internal high pressure form tool consisting of an upper die (3) and a lower die (4), the cavities (5 and 6) thereof enclosing a form chamber (7) for the hollow profiled element. The diameter of said form chamber is smaller than that of the blank (8) of the hollow profiled element to be inserted into the form chamber (7). The aim of the invention is to enable a reliable internal high pressure forming of a blank of a hollow profiled element (8) inserted into the form chamber (7), to obtain the end shape of the hollow profiled element. To this end, a slide (9) can be displaced transversally to the direction of displacement of the form tool (2) when the blank (8) is compressed in the internal high pressure form tool (2) in order to form an intermediate shape (22).
L'invention concerne un procédé et un dispositif (1) pour produire un profil creux fermé au niveau de sa périphérie, au moyen d'une pression fluidique intérieure élevée. Ce dispositif comprend un outil de formage à pression intérieure élevée (2) constitué d'une matrice supérieure (3) et d'une matrice inférieure (4), dont les gravures (5 et 6) délimitent une chambre de formage (7) pour le profilé creux. Le diamètre de ladite chambre de formage est inférieur à celui de l'ébauche de profilé creux (8) à introduire dans la chambre de formage (7). L'objectif de l'invention est de permettre un formage final fiable d'une ébauche de profilé creux (8) introduite dans la chambre de formage (7). A cet effet, un coulisseau (9) peut être déplacé transversalement au sens de déplacement de l'outil de formage (2), lors de la compression de l'ébauche (8) dans ce dernier (2) pour l'obtention d'une forme intermédiaire.
