Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung einstückig ausgebildeter, dreidimensionaler Formkörper, nach dem Verfahren hergestellte Formkörper und eine Vorrichtung zur Durchfürung des Verfahrens. Um die Herstellung einstückig ausgebildeter, dreidimensionaler Formkörper zu vereinfachen und einfach herstellbare dreidimensionale Formkörper zur Verfügung zu stellen, ist gemäß der Erfindung vorgesehen, eine bei Raumtemperatur biegesteife Platte (106) lediglich in Erwärmungsbereichen entlang von Umformlinien, insbesondere Biegelinien (116) zu erwärmen und dann frei im Raum, d.h. ohne Anschlagkante, Kerbe, Lehre oder Gesenk umzuformen, wobei die erzielte Raumform nach dem Abkühlen währenddessen der Materialzuschnitt (106) gehalten wird, dauerhaft erhalten bleibt.
(EN)
The invention relates to a method for producing one-piece, three-dimensional shaped bodies, shaped bodies produced according to the method, and a device for carrying out said method. The aim of the invention is to simplify the production of one-piece, three-dimensional shaped bodies, and to provide three-dimensional shaped bodies which can be easily produced. To these ends, the invention provides that a plate (106) which is resistant to bending at room temperature is heated only in heating regions along deformation lines, especially bending lines (116), and is subsequently deformed freely in space, i.e. without the use of a stop edge, indentation, template or die, whereby the attained spatial shape is permanently preserved after cooling during which the material blank (106) is kept.
(FR)
L'invention concerne un procédé de production de corps façonnés monoblocs tridimensionnels, des corps façonnés produits selon ledit procédé et un dispositif pour la mise en oeuvre de ce procédé. Pour que la production de corps façonnés monoblocs, tridimensionnels soit simplifiée et que l'on puisse disposer de corps façonnés tridimensionnels pouvant être fabriqués de façon simple, il est prévu, selon l'invention, de chauffer une plaque, résistant à la flexion à la température ambiante, simplement dans des zones de chauffage, le long de lignes de déformation, en particulier de lignes de pliage, et de déformer cette plaque librement dans l'espace, c'est-à-dire sans utiliser des arêtes de butée, des encoches, un gabarit ou une matrice, la forme tridimensionnelle obtenue devenant permanente après le refroidissement auquel la découpe de matériau est ensuite soumise.
