Abstract

L'invention concerne un appareil de formage par forgeage à froid ayant une fonction de redirection d'un objet façonné. La présente invention comprend : une partie moule principal comprenant une première partie de guidage, une pente de guidage, une broche d'éjection et une seconde partie de guidage; et une partie moule de poinçon ayant une broche de poinçon. La broche d'éjection commence à se déplacer dans la direction d'une partie orifice d'entrée/orifice de sortie verticale tandis qu'un objet façonné est introduit horizontalement dans la partie moule principal à travers la première partie de guidage par la broche de poinçon et glisse sur la pente de guidage pour être érigé dans la direction verticale, et l'objet façonné est placé sur la surface supérieure d'un socle et de la broche d'éjection et est guidé vers la partie orifice d'entrée/orifice de sortie verticale. La présente invention permet à un objet façonné positionné horizontalement d'être redirigé de façon à être rapidement érigé dans une direction verticale, alors que, de manière classique, un travailleur doit ériger manuellement un objet façonné positionné horizontalement dans la direction verticale. En conséquence, l'invention concerne un appareil de formage par forgeage à froid ayant une fonction de redirection d'un objet façonné, qui peut raccourcir de manière remarquable le temps de production, permettant ainsi d'améliorer la productivité, de réduire les coûts de fabrication et d'améliorer la compétitivité des prix.
