Stamping Die Modelling with Consideration to Drawpiece Springback Phenomenon


Article Preview

Drawpieces made of advanced high-strength steel (AHSS) usable for production of self-supporting car bodies are characterized by the presence of the springback phenomenon caused by the stress relaxation of the elastic part which is the result of stamping. Its compensation requires proper verification of die tools. The presented paper describes a methodology using CAE for die design. The methodology solves an optimization problem determining the verified shape of die tools upon taking into account the consistence of the drawpiece shape with the shape postulated in the project. The real drawpiece was used to judge the usefulness of the methodology in die design.
