Taking the Toyota Camry body as an example,this study discusses the optimization of stamping process parameters and the research on forming quality in the teaching of mechanical manufacturing technology.The orthogonal experimental design and response surface method,combined with finite element analysis,established the mathematical model of stamping process parameters and forming quality.Through the analysis of single factors and interactions,the optimal combination of parameters was determined:the corner radius of the die was 8 mm,the edge pressing force was 650 kN,the stamping speed was 20 mm/s,and the sheet thickness was 1.0 mm.The optimized combination of parameters showed significant improvements in numerical simulations,including downgauging,springback,and stress distribution.The research not only provides a practical reference for the teaching of mechanical manufacturing technology,but also provides new ideas and methods for the improvement of the quality of automobile body manufacturing,which is of great significance for promoting the technological progress of the automobile manufacturing industry.
