The invention discloses a springback process numerical model design method. The method comprises the following steps of: (1) selecting a reference plane and flattening a shape; (2) thickening a curved surface of the shape; (3) calculating a minimum bend radius; (4) drawing segmented sheet bodies; and (5) connecting the segmented sheet bodies to form a continuous curved surface, and obtaining a final process numerical model. By adopting the springback process numerical model design method, the design efficiency is effectively improved, the design cycle is shortened, and an instruction is provided for practical production; and accurate springback amount avoids practical production problems of mold scrapping and the like, thereby greatly increasing the product qualified rate and reducing the manufacturing cost.
