Abstract:
|
Base on the method of numerical simulation,both free cold forging and opened cold forging of shaft with boss were analyzed.In free cold forging,the forming force was small and the life of die was prolonged.But it would cost more raw materials.While in opened cold forging,lots of material would be saved.The forming force could be controlled and the process precision could be ensured,through selecting appropriate cavity height,with the help of FEM analysis software DEFORM.The results show that it is good for simulating the forming process of the boss through numerical simulation,which is helpful to control the forming force in opened cold forging.
