Numerical Simulation on the Roll-forging and Die-forging of Aluminum Alloy Control Arms

The die forging of the control arm has the shortcomings of excessive working procedures,low production rate and high labor strength.The roll-forging and die-forging is proposed.The size of the roll forging of each pass is designed.The numerical simulation takes the place of the physics experimentation.The roll-forging process is simulated by using metal forming finite element code.The bend process and finish-forging use the blank after the roll-forging so that better forging is obtained.The research results provide a theoretical basis for the production practice.
