Abstract：

The stress of multi-cavity die and single cavity die on pre-forging and finish-forging processes were simulated by Deform-3D respectively. The result reveals that the stress distribution of multi-cavity die is better than that of single cavity die. The value of stress is lower. Therefore the multicavity die could meet the requirement for die forging of steering knuckle of heavy truck.For the friction press is weak for unbalance loading, the cavities distribution of this die is optimized. So far, this die has produced 30000 parts and it is still in work.
