Abstract

L'invention concerne, selon un mode de réalisation, un appareil de cintrage permettant de cintrer une pièce à travailler métallique, comprenant : une partie plaque plate qui est disposée à une hauteur prédéfinie par rapport au sol et qui supporte la pièce à travailler métallique ; une partie de déplacement de position dont la position est déplacée dans le sens de la largeur de la partie plaque plate de façon à déplacer la position de la pièce à travailler métallique, tout en entrant en contact avec une première région de la pièce à travailler métallique disposée sur la partie plaque plate ; et une partie de cintrage qui est disposée sur le trajet de déplacement de la partie de déplacement de position, et qui limite le déplacement de position des deux extrémités latérales de la première région de la pièce à travailler métallique liée par le déplacement de position de la partie de déplacement de position, ce qui permet de cintrer la pièce à travailler métallique par rapport à la première région, la partie de cintrage pouvant être façonnée selon une forme correspondant à la surface extérieure de la pièce à travailler métallique, de façon à ce que sa surface externe venant en contact avec la pièce à travailler métallique ne soit pas déformée lorsque la partie de cintrage vient en contact avec la pièce à travailler métallique de façon à cintrer la pièce à travailler métallique.
