Optimization Design of Drawing Blank Spreading Without Flange Box Part

Zhou Liur

Abstract

On the basis of the traditional geometric arithmetic of blank spreading for a box part without flange, the deformation characteristic in drawing process of the box part without flange was analyzed. A new calculation formula of blank spreading for the box part without flange was given, and blank spreading shape counted by the new calculation formula is more precise than that of the traditional geometric method. The edge of the box parts without flange obtained by simulation and experiment is flatter, which is not trimmed. The method is of certain application value.
