Abstract

La présente invention concerne une méthode de pliage de plaque métallique et une installation de mise en œuvre. La méthode comprend les étapes suivantes : a) on fournit, une matrice (12) présentant deux portées d’appui (16, 18) espacées l’une de l’autre, un évidement de déformation (20) situé entre lesdites deux portées d’appui (16, 18), et un poinçon mobile (14) monté au droit dudit évidement de déformation (20) ; b) on installe une plaque (30) d’un matériau métallique présentant deux faces opposées (32, 34), de façon à pouvoir appliquer l’une (32) desdites faces contre lesdites deux portées d’appui  (16, 18) ; c) on entraîne ledit poinçon (14) contre l’autre (34) desdites faces de façon à entraîner ladite plaque dans ledit évidement de déformation (20) pour plier ladite plaque. Et après l’étape b) on fournit de l’énergie thermique localement à ladite une (32) desdites faces entre lesdites deux portées d’appui (16, 18).   Figure à publier avec l’abrégé : Fig. 2The present invention relates to a metal plate bending method and an implementation installation. The method comprises the following steps: a) providing, a matrix (12) having two bearing surfaces (16, 18) spaced apart from each other, a deformation recess (20) located between said two bearing surfaces d support (16, 18), and a movable punch (14) mounted in line with said deformation recess (20); b) installing a plate (30) of a metallic material having two opposite faces (32, 34), so as to be able to apply one (32) of said faces against said two bearing surfaces (16, 18); c) said punch (14) is driven against the other (34) of said faces so as to drive said plate into said deformation recess (20) to bend said plate. And after step b) thermal energy is supplied locally to said one (32) of said faces between said two bearing surfaces (16, 18). Figure to be published with abstract: Fig. 2
