Abstract

The invention discloses a deformation control construction process for multi-curved-surface special-shaped aluminum veneers, which ensures that the processing precision of aluminum plates meets the requirements through first pre-assembly, controls the deformation and angle deviation of the spliced aluminum plate units through second pre-assembly, ensures that the connection among a plurality of aluminum plate units is qualified through third pre-assembly, and can ensure the processing precision of the aluminum plates and ensure the delivery qualification rate of the aluminum plates through three pre-assembly working procedures. Can regard as the scale of control interface size through setting up the shaping board, can in time be found when the aluminum plate unit appears warping, simultaneously under the fixed action of shaping board, also can reduce the deformation when aluminum plate carries out the subsequent process, when hanging the aluminum plate unilaterally in the spraying technology, aluminum plate also can not appear leading to the condition of warping because of the dead weight, under the condition that the spraying roasted, aluminum plate deflection also can very big degree reduce, under the combined action of three pre-assembly process and shaping board, can guarantee that aluminum plate final product can reach preset shape effect.
