Optimization of the Pre-forging of Steering Knuckle

The method of calculated cross-sectional area was used to amend the cross-sectional area of the final forging flash for the automotive steering knuckle forging,so that the corresponding cross-section area of the pre-forging was modified to optimize the pre-forging.Through repeated amendments and modifications,the best pre-forging parts were got ultimately,the material utilization and die life were improved,which provided reference to the optimization of complex forgings.
