Abstract: The push-bending process of aluminum profile was investigated experimentally and numerically. The technical principle and deformation process were researched. The thickness distribution, the curvature after unload and the section distortion of push-bending parts were gotten. The results show that the curvature consistence and section distortion consistence of push-bending parts are high. The forming die is simple and the adjustment is convenient, and the numerical simulation represents the observed response in the laboratory tests fairly well.
Key words: aluminum profile; push-bending process; numerical simulation
