英文摘要 | During the cold forging process of hollow fasteners with a thin flange, a folding phenomenon often occurs. This folding defect affects the fastener's strength, especially the inner folding, and it can lead to sudden failures. The defect usually occurs because the mould's geometric parameters are not appropriate. In order to avoid this folding phenomenon, this paper investigates the optimization of mould geometric parameters in the cold forging process of hollow fasteners with a thin flange, using the finite element method (FEM) combined with the Taguchi method. The simulation results are then compared with experimental data, which show that there is good agreement between the theoretical and experimental results. |
