Embodiment Construction
[0024] The preferred embodiment of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] The invention belongs to the field of precision sheet metal processing, and relates to a hot-press forming method for an aluminum alloy curved-surface stiffener plate, which is suitable for forming an aluminum alloy curved-surface stiffener plate with high requirements for forming dimension accuracy, surface precision and surface quality. The method is as follows: ① Plane unfold the aluminum alloy curved rib plate; ② Prepare the corresponding rib on the plate according to the position of the rib in the plane unfolded diagram; ③ Design and process the hot-press forming mold for the aluminum alloy curved rib plate ; ④ hot-press forming the aluminum alloy curved surface stiffener plate;
[0026] The invention adopts the combination process of hot pressing forming + air-inflating shape correction to form the aluminum alloy curve...
