Abstract

La présente invention concerne une presse à commande hydraulique destinée plus particulièrement au poinçonnage de précision. Elle comprend un coulisseau de presse 2 monté dans un support 1 par l'intermédiaire de chambres de pression 4-6 et d'un piston 3, les chambres de pression comprenant au moins une chambre de pression de commande 5-6 et une chambre de contre-pression 4 alimentées en fluide sous pression par une pompe 15 ou dispositif analogue et est caractérisée en ce qu'elle comporte des dispositifs 8-9 pour déterminer le chemin parcouru par le coulisseau et la vitesse de celui-ci ainsi que 19 la quantité de fluide sous pression refoulée, ainsi que le dispositif de réglage 17-18-19 destiné à contrôler le déplacement du coulisseau en fonction des valeurs mesurées susmentionnées. L'invention permet de commander avec précision la vitesse du poinçon.
