Abstract:
1. A die tool for forming a C-section component having radiused shoulders, the die tool comprising: an inner die having a cylindrical body having a cylindrical outer surface connected to opposing planar end faces by respective radiused convex portions; and an outer die having a cylindrical central portion connected to opposing end flanges by respective radiused concave portions, wherein: a portion of the inner die is arranged to be disposed between the end flanges of the outer die and spaced apart from the end flanges of the outer die to define a cavity corresponding to the desired cross-section of the C-section component to be formed; and, the radiused convex and concave portions having a radius of curvature that varies about a circumference of the respective inner and outer dies; and the inner and outer dies are rotatable such that the radius of curvature of the radiused convex and concave portions varies as the inner and outer dies are rotated, where the inner and outer dies are adjacent to one another.
