Abstract

Une machine asservie de rabattage des bords comporte un système d'entraînement direct entraîné par une servocommande à engrenage planétaire commune située au centre. Une paire de biellettes d'accouplement peuvent actionner une glissière verticalement vers le haut et le bas pour fermer les outils de rabattage et peuvent effectuer l'opération de rabattage désirée. Une boîte d'engrenage planétaire avec des arbres de sortie doubles est couplée directement aux vilebrequins par le biais d'accouplements. L'extrémité inférieure de la biellette d'accouplement peut être connectée à un sommier pivotant fixé à la base de la presse. Un limiteur de surcharge à ressort peut être incorporé entre la base et le sommier pivotant pour protéger la presse contre une surcharge possible dépassant la capacité de tonnage nominale. Le couple désiré permettant d'obtenir le tonnage nominal pour exécuter l'opération de rabattage est fourni directement par un servomoteur relié à la boîte d'engrenage planétaire, ce qui permet d'éliminer le volant-moteur et l'embrayage des anciens systèmes.
