Simulation Analysis of Shell Aluminum Alloy Tube for Neck-In Spinning Process
Authors: Cheng-Shun Chen, Jen-Hsin Ou, Cheng-Jie Hsu
Abstract: Spinning has many advantages, such as good metal malleability, high product utilities, better dimension tolerance, high material efficiency, wider product range, and saving human resources .It has already been widely applied on complex tubular products manufacturing. In the past, this technique was focused on trials of equipment and product. In this study, a three-dimensional elastic-plastic finite element numerical simulation technology will be used to do the inner rib forming analysis by three different mandrel span, and to discuss the distribution of stress and strain during the neck-in inner rib spinning. The effects of support span on neck-in inner rib, mandrel, and product are also studied by different span mandrel forming. The result shows that when the mandrel sustaining span is 50mm, the stress of draw-neck inner rib will exceed its yield material stress and get permanent deformation.
