Numerical Simulation of Cold Extrusion Molding Process of Propeller Shaft Involute Spline

Three dimensional numerical simulation of cold extrusion molding process of propeller shaft involute spline of a motor vehicle is carried out with MSC/Superform software.With numerical simulationthe molding process tracingmechanical field reappearance and molding defect prediction are realizedand cold extrusion molding rules of complicated high accuracy components are exploredand optimization design of blanks and dies is realizedand also criterion is provided for cold extrusion molding production process of spline components. It is shown by process tests that the cold extrusion process and die design are rational and results of numerical simulation and analysis are correct.
