Abstract

Procédé et dispositif de forgeage de pièces permettant une réduction plus grande du métal travaillé grâce à un agencement effectuant le déblocage des matrices à la fin de l'opération de forgeage. Les matrices sont animées d'un mouvement de pivotement autour d'un axe pendant l'opération de forgeage. Au moins une des matrices est supportée par un arbre excentrique et cet arbre tourne à l'issue de l'opération de forgeage de façon à augmenter la distance séparant les matrices et à faciliter leur mouvement de retour. Application au forgeage.Method and device for forging parts allowing a greater reduction of the metal worked thanks to an arrangement effecting the release of the dies at the end of the forging operation. The dies are driven by a pivoting movement about an axis during the forging operation. At least one of the dies is supported by an eccentric shaft and this shaft rotates at the end of the forging operation so as to increase the distance separating the dies and to facilitate their return movement. Application to forging.
