Abstract

Un procedimento per controllare il complesso di azionamento di una macchina deformatrice, in particolare di una pressa idraulica oppure di una fucinatrice ad azionamento idraulico, con almeno un cilindro-pompa comandato da un azionatore a manovella e con cilindri di ritorno sotto pressione di accumulatore a ricarica continua, consente uno spostamento verticale semplice e corse complessive più lunghe quando, dopo una corsa di lavoro, l'alimentazione del mezzo di pressione ai cilin-dri di ritorno viene bloccata e quindi la corsa di ritorno viene ostacolata nonchè il liquido di pressione viene aspirato dal serbatoio a bassa pressione nel cilindro di lavoro della macchina deformatrice e, giusto durante una nuova corsa dì lavoro, l'alimentazione del mezzo di pressione ai cilindri di ritorno viene di nuovo attivata. In un complesso di azionamento di una macchina deformatrice, il cilindro di lavoro della macchina deformatrice è collegato con il cilindro-pompa tramite un condotto allacciato, tramite una prima valvola di non ritorno comandata, ad un serbatoio a bassa pressione e in cui in un condotto che collega i cilindri di ritorno con l'accumulatore del liquido e rispettivamente nel serbatoio a bassa pressione è disposta una seconda valvola di non ritorno comandata.
