Aluminum profile bending forming springback control method and aluminum profile

The invention relates to an aluminum profile bending forming springback control method and an aluminum profile, and the aluminum profile bending forming springback control method comprises the following steps: obtaining a target bending parameter and a mold size of the aluminum profile; pre-stretching with the deformation of 0%-5% is applied to the aluminum profile before bending forming; the forming times are determined according to the pre-stretched yield strength and the target bending center angle; the forming angle of each pass is determined progressively according to the aluminum profile forming times and the target bending center angle; and the outer arc length of the aluminum profile bent in each pass is kept unchanged, and the aluminum profile is bent and formed according to the forming times and the forming angle of each pass. Pre-stretching with certain deformation is applied to the aluminum profile before bending forming, the bent aluminum profile is subjected to springback correction through mult
