Abstract

The effect of percent thickness reduction, feed rate and heat treatment on the forming process of 2A12 aluminum alloy thin-walled shell was studied. The experimental results show that the blank in H112 state was annealed at 380℃×1.5 h, followed by multiple passes spinning, followed by 330℃ × 0.5 h stress relief annealing in the intermediate process, and finally by vacuum air cooling at 495℃×40min. The ellipticity of workpiece can be controlled within 0.12 mm, the tensile strength reaches 490 ~ 517 MPa, and the elongation reaches 13.0~15.5%.
