In the production of stamping parts, the straightening parameters of uncoil blanking directly affects the surface quality and material performance of sheet, and then affects its formability. In order to determine the reliable straightening parameter range, ensure the surface quality and material performance of sheet after uncoiling, and effectively guide uncoiling and blanking production, the hood outer panel was studied. The studied material was AlSiMg alloy of 6000 series with the material thickness of 1 mm, and the material performance was close to the upper limit of the requirement. Then, the materials of different performances were obtained by adjusting the straightening parameter (the height of straightener entrance). And it is confirmed finally that the straightening parameter of hood is more than -0.6 mm (the height of straightener entrance ≥-0.6 mm) by CAE analysis, actual production verification, following hemming process verification and other methods. According to this method, the straightening parameter range of other parts in the production can be determined to reduce the downtime, reduce the risk of unqualified materials, improve the production efficiency and reduce the production costs.
