In order to increase the manufacturing accuracy of the multi-point flexible three-dimensional stretch-bending forming parts of profiles and to determine die-head adjusting parameters quickly and precisely,the intersection of the horizontal axis and the vertical axis in the die unit is defined as the shape-controlling point during the multipoint die rotation forming process according to the geometric relationship between the die head and the profile forming shape.Meanwhile,the curve composited by the shape controlling points in the horizontal direction is defined as the horizontal shape-adjusting line.Then,the relationship between the shape-controlling points in the vertical direction and the adjusting curve of the forming parts is further investigated,and the calculation formulas of the deformation parameters for the die-head shape-adjusting forming process are derived.This method simplifies the adjusting process,and it is of broad applicability.
