The effect of punch profile in deep drawing of dual phase steel

Abstract

From the results of the study found that increasing the radius of the curvature of the nose of the punch increases the contact length between the punch and the blank and increases the height of the produced cup with thinning in the curvature between the base of the cup and its wall. The effect of increasing the radius of the punch’s nose on the drawing load was limited (the load decreases slightly with increasing of R). This work aims to study the effect of the punch’s profile (radius of the curvature of the punch’s nose) in deep drawing process of dual-phase steel.
