The invention relates to a method for producing components from a blank (P1 - P4) consisting of a deep-drawable material, especially steel, using a flowable active medium. During this method, the blank (P1 - P4) is clamped in a forming device (U1,U2) and exposed to the active medium. The blank (P1 - P4) is then preformed by increasing the pressure (P) exerted by the active medium in an area of the blank (P1 - P4) which is limited to a partial section (V1,V2) of the blank surface and which partially covers the surface section (B1,B2) of the blank (P1 - P4) from which the final form of the component is produced. The preformed blank (P1 - P4) is then finished using a forming tool (F1,F2).
L'invention concerne un procédé de production de composants à partir d'une platine (P1-P4) réalisée dans un matériau emboutissable, notamment de l'acier, et à l'aide d'un agent actif fluide. Selon ce procédé, la platine (P1 - P4) est tendue dans un dispositif de formage (U1,U2) et sollicitée par l'agent actif. Ensuite, la platine (P1 - P4) est préformée par augmentation de la pression (P) exercée par l'agent actif dans une zone qui se limite à une section partielle (V1,V2) de la surface de la platine et qui recouvre partiellement la section superficielle (B1,B2) de la platine (P1 - P4), section à partir de laquelle on obtient la forme finale du composant. Enfin, le façonnage de platine préformée (P1 - P4) est achevé à l'aide d'un outil de formage (F1,F2).
