Thermal Coupled FEM Analysis of Precision Roll Forging Performing of Automobile Front Axle

Abstract:

According to the characters, technological condition and requirements of automotive front axle forging, both the process of exact roll-forging billet and die design are studied, as the result, roll- forging die of front axle billet, pre-completed roll-forging die and final roll-forging die are design respectively, finally the groove with hat cross-section is analyzed and top pressure rolling method is proposed during blank-making roll-forging process. The precision rolling forging performing deformation process of automobile front axle is simulated with finite element software Deform-3D by using 3D thermo-mechanical coupled rigid plastic FEM. The metal flow process, equivalent stress and strain field, temperature field and load status of rolling die are analyzed, and they are consistent with experiments. This provides a dependable theoretical basis for understanding the deforming mechanism and selecting reasonable parameters for the precision rolling forging performing of front axle.
