Control of the Variable Blank-Holding Force Based on a New Dual Blank-Holder

Hongying Gong

Abstract

A new dual blank-holder is introduced.Only by changing the structure of the blank-holder,the variable blank-holding force can be controlled continuously and flexibly with this new blank-holder without rebuilding the ordinary hydraulic press.Thus the drawing performance of large and complicated sheet metal parts can be improved.
