Abstract
A new FEM simplified elastoplastic mechanical model is constructed for the backward spinning process of the extra thin-walled shielding can with high ratio of diameter/thickness. The feed mode of the roller adopts the pulsing schedule, which is closer to the actual working condition. Additionally, this new FEM simplified model is significant saving in computing time. In this paper, the metal plastic flow field and the distributions of stress and strain of the deformation zone are studied by the large-scale FEM analysis software MSC.Marc. The causes of the defects of the workpieces are interpreted and the dividing point of the flowing direction of the metal is obtained, accordingly. And the theoretical guidance for the actual processing of the extra thin-walled shield can with high ratio of diameter/thickness is provided. The C-276 shielding can with 0.42㎜ thickness and 561.5㎜ diameter is successfully trial-produced. It proves that above mentioned analysis is reasonable.
