| Abstract: | In this paper, a new precision forming technology is put forward, which combines pre-forging by separable cavity die extrusion-belt type obliterated extrusion with post-forging. It aims at the forming of car steering knuckle, which is a kind of complex branch-like forged piece. The experiment results and numerical simulation results of separable cavity die obturated extrusion are obtained. Then the important conclusion that the new technology can reduce equipment tonnage and increase the utilization ratio of material is educed. |
