Abstract

Die Erfindung betrifft ein Verfahren zum Bearbeiten mindestens eines Flächenelements (1), insbesondere eines Durchbrüche aufweisenden Flächenelements (1), bei dem an das Flächenelement (1) beidseitig je wenigstens eine Lage (12,12') eines verformbaren, mediumdichten Materials angelegt wird, das Flächenelement (1) zusammen mit den verformbaren Lagen (12,12') zwischen wenigstens zwei Formwerkzeugteile (3,4) eingelegt wird und auf mindestens einen Bereich eines Flächenabschnitts des eingelegten Flächenelements (1) bei einer vorgegebenen Umformtemperatur durch Einleiten eines Mediums zwischen eine der verformbaren Lagen (12) und einem ersten Formwerkzeugteil Druck ausgeübt wird. Der Druck wirkt unmittelbar gegen die verformbare Lage (12), so dass das Flächenelement (1) aufgrund des erzeugten Druckes zusammen mit den verformbaren Lagen (12,12') in wenigstens einen benachbarten Hohlraum (9) eines zweiten Formwerkzeugteils (4) hineingeformt wird. Mit diesem Verfahren ist eine Möglichkeit geschaffen, bisher nicht mittels Gasdruck umformbare Flächenelemente, in komplexe, nämlich räumlich gekrümmte Geometrien zu formen.
