Design and analysis of cold stamping process for the car beam left/right section

Abstract

The cold stamping forming processes of the car beam left/right section were designed and analyzed using the CAD/CAE technology and related software. Based on the establishment of the numerical model for the car beam left/right section, the stamping processes of the product were determined through the technical analysis. In particular, the effects of different drawing schemes and parameters (including blank-holder force, blank size, lubrication conditions, etc) on the manufacturability of the product were investigated by numerical simulation technology. The forming effects were evaluated according to forming limit diagram and thickness distribution diagram. As a result, the reasonable process design and optimum parameters are obtained, which can reduce the tendencies of wrinkling, cracking and thickness reduction, and achieve sufficient plastic deformation of the blank.
