Abstract

Chaîne de production automatique pour forgeage de manche de boîte de vitesses comprenant un socle de forgeage (1). Une base de forgeage (2) est disposée sur le socle de forgeage (1). Un bloc de pressage de moule supérieur (3) pour le forgeage capable d'un mouvement de va-et-vient vertical et linéaire est disposé sur la partie supérieure de la base de forgeage (2). Un rail d'alimentation (4) est également disposé au-dessus du socle de forgeage (1). Un élément de stockage de matière (22) est disposé au-dessus du rail d'alimentation (4). Un ensemble d'alimentation automatique (5) pouvant se rapprocher ou s'éloigner de la base de forgeage (2) est disposé sur le rail d'alimentation (4). Un bloc d'alignement en butée (6) est disposé à une extrémité de la base de forgeage (2) à l'opposé de l'ensemble d'alimentation automatique (5). Un tambour d'alimentation (7) est également disposé sur le socle de forgeage (1). L'agencement de l'ensemble d'alimentation, du rail d'alimentation, du bloc d'alignement en butée et du tambour d'alimentation permet à une matière première sur le rail d'alimentation d'être automatiquement poussé sur la base de forgeage. Le bloc d'alignement en butée peut améliorer la précision de déplacement en empêchant la position surélevée de la matière première lorsque la matière première est poussée sur la base de forgeage par une plaque d'alimentation par poussée. La chaîne de production ne nécessite aucune intervention humaine dans le transport, le déplacement et l'approche d'un produit et protège le personnel de travail de blessures thermiques pendant le processus de forgeage. Le niveau d'automatisation est élevé, la consistance du produit est garantie et la qualité d'un produit forgé est améliorée.
