Abstract

La présente invention est relative à un dispositif de cintrage des bords de flans en tôle de grande surface. Dans un dispositif selon l'invention, le flan 10 incurvé à l'avance est immobilisé sur un support 12 par un vérin 24. Un outil de cintrage mobile 30, porte par un support équilibré, se déplace le long du bord en cintrant le bord en le pressant contre un support ou une enclume avec des pièces de formage formant un ensemble non plan, actionné par vérin. Application à la fabrication de réservoirs soudés de grandes dimensions.The present invention relates to a device for bending the edges of sheet metal blanks with a large surface area. In a device according to the invention, the blank 10 curved in advance is immobilized on a support 12 by a jack 24. A mobile bending tool 30, carried by a balanced support, moves along the edge while bending the edge. by pressing it against a support or an anvil with forming parts forming a non-planar assembly, actuated by cylinder. Application to the manufacture of welded tanks of large dimensions.
