Abstract
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum wirkmediengestuetzten Umformen eines flaechigen, insbesondere mehrlagigen, Halbzeuges mit einem geteilten Hydroformwerkzeug, bei dem an gegenueberliegenden Seitenflaechen des Halbzeuges im umzuformenden Bereich desselben einander entgegenwirkende Wirkmediendruecke angelegt werden.
DE 10355959 A UPAB: 20050728 NOVELTY - Method for active fluid media supported deformation of a multi-layer semi-finished product, e.g. a welded, bonded or rolled blank or a tailored tube. According to the method the active fluid medium is supplied to opposite sides of the product so that in the area to be deformed opposite media pressures are applied against each other. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is made for a device for active fluid media supported deformation of a multi-layer semi- finished product. USE - Method for active fluid media supported, e.g. hydroforming, deformation of a multi-layer semi-finished product, e.g. a welded, bonded or rolled blank or a tailored tube, e.g. for use in production of vehicle components, apparatus construction and production of lightweight complex components and structures. ADVANTAGE - Components can be produced with optimized technological properties and minimal manufacturing costs. More severe deformation gradients can be produced without causing localized failure.
