Abstract

Installation pour machine pourvue d'au moins un cylindre de contre-pression pour retarder la détente du bâti de presse lors du passage de l'outil à travers la pièce. Installation caractérisée par un circuit de régulation de pression, comprenant un boîtier de mesure de pression, un comparateur de valeurs de pression de consigne et réelle, commandant, avec amplificateur, une soupape de régulation proportionnelle 28, connectée au cylindre de contre-pression 13, ce circuit étant pourvu d'un organe d'intégration 42, 43 réglé sur une pression juste suffisante pour la sortie du piston du cylindre de contre-pression. Installation applicable directement à tous types de presses à estamper.Installation for a machine provided with at least one counter-pressure cylinder for delaying the expansion of the press frame when the tool passes through the workpiece. Installation characterized by a pressure regulation circuit, comprising a pressure measurement box, a comparator of setpoint and actual pressure values, controlling, with amplifier, a proportional regulation valve 28, connected to the back-pressure cylinder 13, this circuit being provided with an integration member 42, 43 set to a pressure just sufficient for the piston to exit the back pressure cylinder. Installation directly applicable to all types of stamping presses.
