| Abstract Scope |
Magnesium alloy cylindrical parts with inner ribs (MACPIR) are attractive as lightweight components for improving the performance of high-end equipment in various industrial sectors. Induction-heating assisted spinning (IHAS), an effective way to manufacture cylindrical parts made of difficult-to-deform materials, was used to form the MACPIR. However, when using this process for MACPIR, nonuniform deformation and other forming defects can easily occur between the cylindrical wall and inner ribs. An FEM model of MACPIR during IHAS was developed via ABAQUS, and experimental verification was conducted. Forming defects that occurred during the spinning process of MACPIR were analyzed, and evaluation indexes of forming quality were proposed. The results show that the concavity of rib back, and nonuniform distribution of rib height along tangential and axial directions are the main forming defects. Additionally, the influence of process parameters on the forming quality was discussed. The results indicate that the forming quality of MACPIR can be improved under a forming temperature of T=300~350℃, roller feed rate f=0.4~0.6mm/r and thinning ratio of wall thickness Ψt=65~75%. The simulation results confirm well with experimental ones. |
