Abstract：

The structural characteristics of 5A06 aluminum alloy thin-walled profiled part and the forming process were analyzed, and the multi-pass compounding process scheme of cold forming and hot forming was conducted. Then, the profiled surface stamping, the round hole flanging, and the window flanging were numerically simulated by the analysis software, the wrinkle and cracking defect area produced easily were predicted, and the hot forming solution was put forward. Furthermore, the blank was reversely produced, and the final blank size was optimized. The die was designed, and the experiments including profiled surface hot forming, round hole cold flanging and near-rectangular window hot flanging were carried out. The gap between the main body surface of the test workpiece and the test sample was less than 0.5 mm, and wrinkles and cracking defects did not occur. The test results were consistent with that of the finite element analysis, which proved that finite element analysis had a strong guiding significance for the study of plastic forming process of aluminum alloy profiled thin-walled components, and the hot stamping+cold flanging+cold bending+hot flanging composite plastic forming were feasible.
