Embodiment Construction
[0020] refer to image 3 It is a process flow chart of the multi-point forming method for an aluminum alloy aircraft integral wall panel of the present invention. The aluminum alloy aircraft integral panel is an aluminum alloy integral panel with I-shaped, T-shaped or J-shaped high ribs, and the structure of the ribs is Unidirectional distribution, grid structure or rice-shaped structure, the upper and lower multi-point molds 1 and 5, which can be quickly reconstructed, are used to form aluminum alloy aircraft with rib structure according to the planned deformation path Integral panel 3 divides the large target deformation into multiple steps non-uniformly, gradually changes the shape of the forming surface of the multi-point mold, and performs gradual counter-press forming, and finally obtains the required large-deformed aluminum alloy aircraft through the gradual accumulation of small deformations Integral wallboard 3, this method comprises the following steps:
