Research on bidirectional deep drawing forming of U-shaped frame part
Aiming at the problems of unstable forming quality and large amount of manual trimming for U-shaped frame parts,through the analysis and research on the structure of the parts,the process supplement surface was designed by means of CATIA,and the forming process was simulated by numerical simulation,and the bidirectional deep drawing forming process was studied.The bidirectional deep drawing die structure with a special force transfer mode was designed.The four factors of convex and concave die gap,friction factor,pressing force and deep drawing speed were selected as the optimization variables,and the optimal combination of process parameters was obtained through orthogonal tests,that is,the pressing force is 30 kN,the friction factor is 0.1,the convex and concave die gap is 1.6 mm,and the deep drawing speed is 6000 mm·s-1.Finally,according to the phenomenon of springback after drawing,the correction die was analyzed and designed for trimming.The production tests show that the die structure can improve the forming quality of parts,improve the efficiency and meet the production and design requirements.
