Abstract

Le dispositif de formage présente une matrice (12) incluant une face d’impact (24) et un moyen (30) magnétique associé apte à générer un champ magnétique transversal et sortant par rapport à l’orientation de la face d’impact. Lorsque le dispositif exerce une force de poussée ou répulsion sur une tôle (2) ou similaire en matériau électriquement conducteur, suivant une direction déterminée (A), une partie (2a) de cette tôle est déformée ou pliée dans une zone réceptrice de la matrice, en étant projetée vers la face d’impact avec une vitesse importante. Le moyen magnétique, disposé du côté de la matrice (12) et générant le champ magnétique, constitue un système de freinage à courants de Foucault pour réduire la vitesse de la partie (2a), lorsque celle-ci s’approche de la face d’impact (24) et se situe dans la zone d’action du champ magnétique, améliorant la précision du formage. Figure de l’abrégé : Figure 4The forming device has a die (12) including an impact face (24) and an associated magnetic means (30) capable of generating a transverse and outgoing magnetic field relative to the orientation of the impact face. When the device exerts a pushing or repulsive force on a sheet (2) or similar made of electrically conductive material, in a determined direction (A), a part (2a) of this sheet is deformed or folded in a receiving area of the matrix , being projected towards the impact face with significant speed. The magnetic means, placed on the side of the matrix (12) and generating the magnetic field, constitutes an eddy current braking system to reduce the speed of the part (2a), when it approaches the face d impact (24) and is located in the zone of action of the magnetic field, improving the precision of forming.
