CA 2322545

During manufacture of certain hollow profiles suitable for use in car body construction the welded profiles are subjected to a further deformation process, namely hydroforming. At present the corresponding welding machines are charged manually. The invention relates to a method and a device for transferring hollow-profile blanks, characterized in that during transfer the positioned fusion faces of the blanks are pressed against each other at least in the area of the weld.

Dans la fabrication de certains profilés creux utilisés pour la construction de carrosseries, les profilés soudés sont soumis à un autre processus de déformation, à savoir, à une hydrodéformation. Les machines de soudage correspondantes sont actuellement alimentées manuellement. L'invention concerne un procédé et un dispositif pour le transfert d'ébauches à profilés creux, caractérisés en ce que, pendant le transfert, les bords des joints positionnés des ébauches sont compressés les uns contre les autres au moins dans la zone de la soudure.
