Abstract

L'invention concerne un dispositif de fabrication d'un élément métallique pourvu d'au moins deux zones aux propriétés de résistance différentes. Ledit dispositif est constitué d'une unité de chauffage (2) pourvue de sources de rayonnement (4) produisant de la chaleur ainsi que d'un dispositif de positionnement pour au moins un corps de base (1) en métal, d'un dispositif de protection pourvu d'au moins une partie de recouvrement et destiné à protéger sans contact une zone de surface prédéfinie du corps de base (1). Le dispositif de protection est conçu pour demeurer dans l'unité de chauffage, pendant une thermorégulation du corps de base (1) avant que celui-ci ne soit façonné dans un outil de façonnage. La partie de protection comporte plusieurs parties de recouvrement (3a, 3b, 3c, 3d, 3e) pouvant être manipulées séparément, qui sont destinées chacune à protéger une zone de surface (1a, 1b, 1c, 1d, 1e) prédéfinie du corps de base (1), et pour chaque partie de recouvrement (3a à 3e) est agencé un manipulateur (5), au moyen duquel la partie de recouvrement (3a à 3e) peut être déplacée indépendamment des autres parties de recouvrement (3a à 3e) dans l'unité de chauffage (2) dans une position de recouvrement, dans laquelle elle recouvre la zone de surface (la à le) prédéfinie, ou dans une position de libération, dans laquelle elle libère la zone de surface (la à le) prédéfinie pour les faisceaux des sources de rayonnement (4).
