Abstract

[PROBLÈMES] L'invention concerne un procédé d'assemblage de tôles métalliques et un dispositif de ponçage. Le procédé est approprié pour réparer la partie endommagée d'une tôle métallique par exemple d'une carrosserie de véhicule, et la partie endommagée d'un métal non ferreux de bâtiments et de machines ou la partie endommagée d'une paroi périphérique non ferreuse. Le procédé est apte à réaliser un assemblage à deux dimensions ou à trois dimensions, de pièces à fleur l'une avec l'autre, réunies ou réparées de carrosseries en tôle ayant des surfaces courbes particulièrement complexes, et à assurer un fini avec précision et esthétique, et est capable de réaliser de façon raisonnable et facile une telle opération d'assemblage. [MOYENS POUR RÉSOUDRE LES PROBLÈMES] Deux corps de plaque (5, 7) devant être réparés et assemblés l'un à l'autre sont disposés de telle sorte que leurs extrémités à réunir sont séparées l'une de l'autre dans la direction de l'épaisseur de la plaque ou dans la direction perpendiculaire à la direction de l'épaisseur de la plaque. Dans le procédé, des pièces de jonction (6, 31) formées d'un seul tenant avec ou séparément de la tôle métallique sont disposées d'un côté des extrémités devant être assemblées. Les extrémités à assembler sont amenées à adhérer aux pièces de jonction (6, 31). Avant qu'un agent adhésif (10) ne soit durci, une plaque de pression (12) est disposée sur les autres surfaces latérales des extrémités devant être assemblées. Des dispositifs d'attraction (15), ayant chacun une force magnétique, sont installés sur la surface de la plaque de pression (12). La plaque de pression (12) est adaptée aux autres surfaces latérales des extrémités à assembler par la force magnétique des dispositifs d'attraction (15). Les extrémités devant être assemblées sont attirées et déplacées par la force magnétique, et, comme résultat, les extrémités sont disposées à fleur l'une avec l'autre avec référence à la plaque de pression (12).
