For the cold stamping of marine double-curvature plate part, selecting the stamping direction with the bending deformation as the main way can improve the cold stamping formability of part. However, the springback is one of the inevitable problems for sheet metal bending and greatly influences the cold stamping precision of plate part. Therefore, the cold stamping and unloading springback process of double-curvature plate part were simulated numerically by the dynamic-explicit algorithm and the static-implicit algorithm respectively, and the die was compensated and designed iteratively by three times based on the springback prediction. The final thickness of sheet metal decreases no more than 10% and increases no more than 5%, and no serious thinning and wrinkle defects occurred. The deviation between formed sizes and designed sizes of part is less than 3 mm, the shape deviation decreases more than 50%, and its forming precision is effectively improved. Furthermore, the cold stamping experiment for double-curvature plate part was carried out, and the shape and sizes of part were measured to verify that the cold stamping of part met the design requirements.
