Abstract

L'invention concerne un appareil de forgeage de bague métallique, selon un mode de réalisation de la présente invention, qui est destiné à usiner une bague métallique, qui a un premier diamètre externe et une partie creuse, de sorte que la bague métallique a un second diamètre externe qui est plus grand que le premier diamètre externe, et qui peut comprendre : une unité de lit ayant une partie de base disposée de façon à être parallèle au sol à une hauteur prédéterminée ; une unité de chargement pour déplacer la position de la bague métallique d'une position d'attente, qui est sur le côté externe de l'unité de lit, à une position d'usinage, qui est sur le côté supérieur de l'unité de lit ; une unité de rouleau de mise en forme formée sur le côté supérieur de la position d'usinage et tournée dans une première direction, et effectuant un mouvement de va-et-vient entre une première position dans laquelle l'unité de rouleau de mise en forme est disposée pour être espacée de la bague métallique positionnée dans la position d'usinage et une seconde position dans laquelle l'unité de rouleau de mise en forme vient en contact avec au moins une partie de la surface périphérique externe de la bague métallique ; une unité de mandrin formée entre l'unité de lit et l'unité de rouleau de mise en forme, et portant la bague métallique tout en étant insérée dans la partie creuse de la bague métallique lorsque la bague métallique est positionnée dans la position d'usinage ; et une unité de rouleau de support formée entre l'unité de lit et l'unité de mandrin, et définissant la limite du diamètre externe de la bague métallique en fonction de l'usinage à l'aide de l'unité de rouleau de mise en forme et de l'unité de mandrin.
