Abstract

L'invention concerne une presse (21) comprenant au moins un cadre de presse (9), une table montée dans ce cadre et un coulisseau (5) entraîné par l'intermédiaire d'au moins un mécanisme bielle-manivelle (12), une partie supérieure d'outil (6) étant placée sur le coulisseau (5) et une partie inférieure d'outil (7) étant placée sur la table (8) de la presse, au moins un vilebrequin (1) qui comporte au moins un maneton (2) et au moins une bielle (3) étant monté en tant que mécanisme bielle-manivelle (12), et au moins un entraînement direct qui entraîne le vilebrequin (1) de manière directe étant monté en tant que moteur (14) pour l'entraînement du vilebrequin (1). Le but de l'invention est de réaliser une presse dans laquelle les forces appliquées côté entrée par l'entraînement direct peuvent être transmises côté sortie avec une sollicitation sensiblement plus faible du vilebrequin et, en même temps, la rigidité globale de l'ensemble transmission est augmentée de manière significative et/ou la longueur de l'ensemble transmission est minimisée. A cet effet, au moins un moteur (14) est placé entre deux bielles (3) dans le cas de l'agencement d'au moins un moteur (14) à l'intérieur d'une presse (21) comportant au moins deux bielles (3) sur au moins un vilebrequin (1).
