Multi-stages necking process and mechanism of precision thin-walled can

  • Received Date: 08 Jul 2010

  • Based on the multi-stages necking process of the precision thin-walled can, the deformational behavior of the material in each stage necking process was analyzed, the first necking process and the subsequent necking process was distinguished, and the definition of the die angle was given out. The control law of necking stroke in each process was investigated and verified by utilizing numerical simulation. The experiment results using a special equipment were obtained, which indicate the diverse analytical basement between different necking process. The load computational formula of different necking stages were derived based on slab method, indicate the existence of optimal die angle in each necking process. The calculated load results coincide with the experimental results, and the change of the necking load along with variation of die angle was obtained.
