Abstract:

According to the shape characteristics of multi-step shaped shaft, a three step ironing process was designed. Both finite element method and experiments were employed to analyze the deformation process and the rule of dimension change in ironing. The results show that the three-step extrusion process is feasible. During multi-step ironing, the diameter of force transmission zone near the entrance of die will increase due to upsetting. And whether in finite element simulation or in experiment, the reduced diameter after ironing in any step is in line with the design value.
