| Abstract Scope |
The paper was concerned with plate forging of Al5052. Biaxial tensile tests were conducted to obtain the rheological behavior and stress-strain curve of Al 5052 under warm temperature. An FEM model utilizing the data mentioned above was proposed to simulate the solid boss process of Al5052 by sheet-bulk forming. It was interesting to find out that boss height and forming defects vary with the combination of process parameters. Thus five factors and four level orthogonal experiment table was designed to study the effect of counter-punch force, boss diameter, boss radius, initial sheet thickness and friction coefficient on boss height and dimple defect. The results indicated that boss diameter and counter-punch force play the most important role on the boss height and defect, respectively. Finally, the corresponding experiments were consistent with the numerical prediction results. |
