Quality and Properties of Curved Aluminum Alloy Profile Formed by Extrusion-Bending Integration Process

Through rebuilding traditional extruder and increasing a bending device, the profile was formed by extrusion-bending integration forming process, and the effects of roller radius and roller movement rate on forming quality were studied. The optimal process parameters of the roller radius and roller movement rate were obtained basing on finite element simulation. The results show that the forming capability of the aluminum alloy profile was fair good when the extrusion rate of the profile and roller movement rate were same.The extrusion-bending integration process could avoid the defects as follows: rebound, surface scratches and cross-section deformation, which were common during conventional drawing and bending process. The extrusion-bending integration process increased the uniformity of mechanical properties of the curved profile.
