A method and an apparatus are provided for internal high-pressure forming of a workpiece in a closed internal high-pressure forming die. The workpiece is expanded owing to the internal high fluid pressure exerted by a pressure generator and coming to rest on the cavity of the forming die. The workpiece and the forming die form friction partners in the areas of contact. In order to improve process reliability during the internal high-pressure forming of workpieces and to expand the scope of the method, vibration is imparted directly to at least one of the friction partners by a vibration generator during forming.
Procédé et dispositif (1) de formage sous haute pression interne d'une pièce (2) dans un outil fermé de formage (3) sous haute pression interne. Selon ledit procédé, la pièce (2) est étirée grâce à la haute pression interne élevée fluidique exercée par un générateur de pression et repose contre le relief de l'outil de formage (3), la pièce (2) et l'outil de formage (3) formant des antagonistes de friction dans les zones de contact. Selon la présente invention, pendant le formage, l'un des deux antagonistes de friction au moins est amené à osciller sous l'effet d'un oscillateur, ce qui permet d'améliorer la sécurité du processus de formage sous haute pression interne de pièces (2) et de repousser les limites dudit procédé.
