Bending Method for Forming Curvature and Various Cross-Section Shapes

Abstract:

Previous studies on the bending process of extruded aluminum alloys have focused on a high-precision bending process that controls various undesirable phenomena. In contrast, this paper proposes a new bending method in which undesirable deformations are intentionally occurred and can be deformed into an arbitrary cross-sectional shape. By bending the extruded section, we sought to establish a novel bending process, in which a curvature and cross-sectional shape are produced in a single process. Undesirable deformations that occur by bending channel materials with a removed tensile flange include both the outward and inward deformations of the webs. Based on such deformations, this report proposes several types of cross-sectional shapes that can be formed through simulations and press bending experiments.
