The forming process of fender was analyzed by simulation analysis software CAE,and the key elements and considerations in the design of stamping process plan for fender were summarized by combining a lot of CAE analysis data with practical process design experiences.Then,the advantages and disadvantages of process plans for both double and single parts were described respectively,and the functions,design method and basic requirements of stamping direction,blank holder surface and process supplement in the drawing process,as well as the contents,their respective characteristics and the considerations of the later processes were introduced emphatically. In addition,the feasible solutions to the process problems which were easy to appear in the design were given which were verified by CAE analysis and practical production,and the method of optimizing the local characteristics of parts was introduced to improve the stamping processability. After the verification of production,the design plan proposed is reasonable in processability and stable in product quality,and meets the needs of large-scale production.
