Abstract
L'invenzione concerne un procedimento per la ottimizzazione iterativa di processi di imbutitura alla pressa, eseguiti ciclicamente. La forza di bloccaggio regolabile sul premilamiera viene ridotta (in caso di graffietti) oppure aumentata (in caso di grinze) oppure viene mantenuta costante (in caso di pezzi buoni) a seconda della qualità del pezzo imbutito in un ciclo produttivo precedente per un ciclo produttivo successivo. Per poter riconoscere automaticamente e in ogni ciclo produttivo la qualità del pezzo imbutito e, di conseguenza, per poter realizzare il processo di ottimizzazione come processo di regolazione automatico in un circuito chiuso, prima di iniziare la produzione di un determinato tipo di pezzo da imbutire si rileva, mediante un'analisi dell'emissione del suono sostantivo prodotto dal pezzo durante il processo di imbutitura nell'utensile relativo, l'andamento normale del suono di imbutitura, si memorizzano i dati relativi ad esso e da ciò si rileva, inoltre, un andamento di livello caratteristico di quote sonore periodiche e stocastiche e si memorizzano pure i dati relativi ad esso. Durante la produzione dei pezzi si esamina il segnale del suono sostantivo ogni volta dal punto di vista della contemporanea manifestazione di salti anormali di ampiezza in un ampio spettro di frequenze ed eventualmente si desume l'esistenza di "graffietti". Inoltre si esamina il segnale del suono sostantivo ogni volta dal punto di vista dell'andamento temporale del livello di quote sonore da periodiche a stocastiche ed eventualmente si desume l'esistenza di "grinze".
