Abstract

Dans le procédé décrit, on applique une précontrainte au profilé métallique pratiquement droit à l'origine, lequel est soumis à un serrage aux deux extrémités. Puis, le profil métallique précontraint est cintré dans un outil de cintrage rotatif. Afin de réaliser un formage tridimensionnel du profilé, l'outil de cintrage effectue un mouvement contrôlé dans la totalité des trois axes spatiaux, le profilé métallique étant pressé, avec un système de guidage sans jeu, au moins dans la région de formage contre l'outil de cintrage et guidé par liaison de forme.
