Abstract

L'invention concerne une matrice de pliage (1) d'une pièce de chaudronnerie (4) pour une machine de pliage. La matrice comprend deux supports (2, 3) distant l'un de l'autre pour permettre le pliage ladite pièce entre ces supports, et deux rouleaux (5, 6) montés en liaison pivot sur les supports avec un espacement entre ces rouleaux permettant à la pièce de chaudronnerie de prendre appui sur lesdits rouleaux lors du pliage. La matrice permet d'augmenter les capacités de pliage et de contre pliage des pièces en augmentant les rayons de courbure, et réduit la dégradation de la pièce durant son pliage. Les rouleaux (5, 6) sont amovibles des supports, ladite matrice de pliage comprenant au moins une paire de bagues (21) configurée pour être ajoutée sur les rouleaux (5, 6) de sorte à réduire l'espacement entre ces rouleaux, la pièce de chaudronnerie prenant appui sur les bagues (211, 212, 213, 214).
