Studies on the push-bending process of aluminum section profile

Push-bending of two generic aluminum sections profile is investigated experimentally and numerically. The aluminum profile can be formed into a complicated part such as 360 abnormity section circle parts that is difficult to be manufactured by other techniques. In this paper, the push-bending principle, deformation procedure, force-distance curve, curvature spring-back and section distortion are studied. The part is formed point-by-point along the profile. All cross-sections for the profile are provided a rather homogenous deformation degree. The curvature value of component and the distortion of section keep high consistence in push-bending process. The push-bending force can be decreased obviously by lubricant. The numerical model represents the observed response in the laboratory tests fairly well.
