Abstract
Ce dispositif comprend une barre d'accouplement 30 qui confère au coulisseau 16 de la presse une vitesse qui limite l'élévation de la force de découpage à une durée inférieure à la période de fréquence propre des organes situés sur le parcours de transmission de forces. La manivelle 33 et la barre d'accouplement 30 sont reliées entre elles par au moins une bielle 32. Au moins une barre oscillante 31 s'appuyant au bâti de la presse est articulée sur le point de liaison entre la bielle et la barre d'accouplement.This device comprises a coupling bar 30 which gives the slide 16 of the press a speed which limits the rise in the cutting force to a duration less than the period of natural frequency of the members located on the force transmission path. The crank 33 and the tie rod 30 are interconnected by at least one connecting rod 32. At least one oscillating bar 31 resting on the frame of the press is articulated on the point of connection between the connecting rod and the bar of coupling.
