Abstract

Procedimento per lo stampaggio di lamiere metalliche che prevede di utilizzare una pressa idraulica il cui premilamiera viene comandato in modo da esercitare sulla lamiera in fase di stampaggio una pressione di trattenimento variabile alternativamente, con una frequenza prefissata, tra zero ed un massimo prefissato, il valore della pressione massima e della frequenza dipendendo dalle caratteristiche della lamiera da stampare.
