Research on springback compensation scheme of upper sec-tion of automobile luggage outer plate
Taking the upper section of a car luggage outer plate as an example,the characteristics of its stamping process scheme were introduced.The clamping flanging process scheme was adopt-ed in both front and side flanging,and the springback was controlled within 1.5 mm,which provid-ed the feasibility of curvature continuity for the A surface springback compensation.With the help of AutoForm-PD software,the parametric springback compensation of A surface was realized,and the A surface characteristics of curvature convexity-concavity,high light zebra crossing,and curva-ture comb were consistent with the original parts.Finally,the AutoForm was used to analyze the springback after compensation,and the overall part size was controlled within±0.3 mm,which ver-ified the feasibility of the stamping process scheme and the springback compensation strategy.
