Study on the Springback Characteristics of CR340LA Steel during the Typical Auto Part Stamping Process

Abstract:

Metal sheet Stamping forming is an important material forming process, especially in the automobile industry. Using the advanced FEM simulation technology, precise analysis of the metal sheet stamping forming process becomes possible, which provides the scientific evaluation of the process design and die design in sheet stamping forming. So the paper chooses a topical auto drawing part-auto indoor-still part and applied the CR340LA steel to have stamping numerical simulation test by the numerical simulation analyzing software-Dynaform. In the stamping numerical simulation test, the best binder holder force values, stamping speed values and the spring back forecast results are got. Then the springback forecast results of the numerical simulation analysis tests are applied to the actual production to overcoming the spring back effectively, and the successful products are got.
