Abstract

Ce dispositif pour l'équilibrage automatique du coulisseau d'une presse par des cylindres pneumatiques utilise un organe de mesure qui, en fonction de la charge due au coulisseau et à l'outil, commande un régleur des soupapes d'échappement et d'admission pour rétablir l'équilibre dans les cylindres pneumatiques. Cet organe de mesure est un levier palpeur 1 dont une partie la coopère avec l'écrou 4 de la vis de presse et dont l'autre partie 1b coopère avec des éléments de commande 5, 6 pour les soupapes d'échappement et d'admission 7, 8 du système d'équilibrage.This device for the automatic balancing of the slide of a press by pneumatic cylinders uses a measuring device which, depending on the load due to the slide and the tool, controls an adjuster of the exhaust and intake valves. to restore balance in the pneumatic cylinders. This measuring member is a feeler lever 1, a part of which cooperates with the nut 4 of the press screw and of which the other part 1b cooperates with control elements 5, 6 for the exhaust and intake valves. 7, 8 of the balancing system.
