Utilizing 2-D and 3-D simulations in assisting tooling design in Chain-die forming threshold product

With the increasing demand of reducing the body weight of automobiles, the utilization of advanced high strength steel has increased dramatically in recent years. However, high residual stress and redundant strain caused by the traditional cold roll forming process is still an outstanding problem. Under such circumstances, the Chain-die forming method is developed as a novel sheet metal forming approach which combines roll forming and stamping...
