| Abstract: | The sheet metal appearance small rounded corner(R1.5mm)process of the matching place between the wing and the front bumper,and the matching place between the side wall and the rear bumper of a certain car was studied and verified.Though the methods of optimizing stamp?ing direction,over drawing process supplement design and optimizing CAE analysis parameters,the problem such as irregular rounded corner,cracking,wrinkling were solved,and the rationality of the process had been verified by the field stamping,which was of great significance to form and popularize the matching small rounded corners of R1.5 mm and below. |
