Abstract：
|
|
A process that making steering knuckle horizontally with 5 steps in one multicavity die on a new friction press for die forging was introduced.After analyzing the formability character of the technology,the process(upsetting→local upsetting→gathering stock→preforging→finish-forging)was defined.The forging process was simulated by Deform-3D.Velocity field,strain-stress distribution and load curve were obtained,which provided basis for die design and optimization as well as equipment selection.Besides,the potential defect,such as fold was also predicted in simulation.
