Abstract
Un dispositif de cintrage (10) comporte deux poinçons de formage (12, 14) munis de chambres de formage (22, 24), se présentant de manière à effectuer un cintrage d'un flan (26) autour d'un noyau (16). Chacune des longueurs périphériques des deux chambres de formage (22, 24) est supérieure à la moitié de la périphérie de la boîte. Au cours d'une étape de préformage, le noyau (16) pénètre dans une première chambre de formage (22) sur une distance supérieure au rayon de la boîte. Le flan (26) est ainsi façonné en U. Au cours d'une étape de formage intermédiaire, un noyau auxiliaire (18) est monté sur le noyau (16), de manière à ce que lorsque le second poinçon de formage (14) descend, seules les extrémités des branches du U de l'ébauche de flan (26) soient cintrées en arc de cercle. Après éloignement du noyau auxiliaire (18) et d'une partie (20) du premier poinçon de formage (12), a lieu l'étape de formage final de la boîte, au cours de laquelle le second poinçon de formage (14) passe également au-dessus du centre de la boîte. Ce procédé de cintrage en trois étapes permet de cintrer des boîtes de manière très précise, sans les altérer.
