Abstract：

For the large ribbed 5A06 aluminum alloy sheet part with complex shape, uneven volume distribution and cross-sectional area asymmetry, the die structure was optimized and a reasonable forming process scheme was determined based on the study of isothermal extrusion process scheme and the forming defects for large aluminum alloy 5A06 sheet with rib. At the same time, the technological parameters were optimized. In the final scheme, three kinds of bosses were added to the design of punch structure: boss with 8 mm high and the edge sagging with 5, 10 mm high and 10 mm wide, and the corresponding positions of dies were also added bosses with 2 and 3 mm high respectively. Furthermore, the angle between two sides of the boss on the right side of the die was changed from the original 45° into 30°, while the upper edge chamfer was 10°。
