Izbor promenljive sile držanja pri dubokom izvlačenju

Abstract

Blank holding force is significant parameter which is possible to change during the process of deep drawing. Variable blank holding force (VBHF) enable to influence on work part behaviour and also on final results of the process. Presented in the article is original way of one kind of VBF dependence determination and part of experimental results obtained with low-carbon autobody steel sheet metal. Experiment is realized on special laboratory researching equipment with computer based control. Given is comparative view of results in conditions of constant blank holding force defined on classic way.
