Abstract

The springback is one of the key factors affecting the forming quality of 5052 aluminium alloy sections with hat profile in rotary draw bending. To study the effects of material parameters of the sections on springback, the elasto-plastic finite element bending model and unloading springback model of the process were proposed based on ABAQUS Explicit/Standard platforms. Then, the influence regularities of material parameters on springback during the process were investigated using finite element method combined with experimental and theoretical researches. The results show that springback angle and radius increase with the increase of strength factor and yield strength while decrease with the increase of Young’s modulus and strain-hardening exponent. Then, the material selection for reducing the springback of aluminium alloy section with hat profile in bending is obtained. The achievement can provide a guideline for controlling springback and selecting the material of the aluminium alloy profile rotary draw bending process.
