Bending forming method suitable for ultra-large and ultra-thick aluminum alloy equal-thickness wall plate

The invention relates to a bending forming method suitable for an ultra-large and ultra-thick aluminum alloy equal-thickness wall plate, and belongs to the technical field of advanced manufacturing. Comprising the following steps: processing a blank into a wallboard according to a required size; hoisting the plate, putting the plate into two shafts in the middle of equipment, aligning, adjusting the two main shafts to press the wall plate, rotating the rolling shaft to adjust the generatrix of the rolling shaft to be perpendicular to the reference edge of the wall plate, and keeping the state in the whole forming process; meanwhile, one of the rolling shafts on the two sides is adjusted to make contact with the surface of the wall plate, and the distance value of the rolling shaft is recorded; recording the distance data of the rolling shaft at the moment when the wall plate arches; continuously adjusting the rolling shaft, gradually forming the radian of the wall plate, detecting the radian condition of the
