Optimization of a Cold Forging Die Design Using Simulation Software

The article presents an approach to predict cold forging product quality by simulation method and AHP method. The modern method to achieve stable product quality and recommend suitable technological parameters is to analyze simulation results. Technological improvements achieved by modifying the geometry of the die and the forging process reduce flow defects and stress concentration in critical areas. CAE simulations such as QForm allow finding optimal interference values that provide compressive stress states in complex but fragile inserts under actual forging loads. Plastic strain and defects of forged products can be predicted and minimized by simulation. The presented model is realized in the commercial metal forming simulation software Qform
