The multi-directional forging process of sintered pure molybdenum was numerically simulated by Deform-3D three-dimensional geometric modeling software, and the model diagram was established using Pro-Engineering three-dimensional geometric modeling software. The Langrangian incremental form is selected to calculate the plastic deformation during the forging process. A single step is calculated by the conjugate gradient method, and direct iteration is used between calculation steps. The forging anvil is in contact with the forging, the temperature of the forging anvil is 300 ℃, the interface heat transfer coefficient is 5 N/(sec·mm·℃), the ambient temperature is 20 ℃, and the heat convection coefficient is 0.02 N/(sec·mm ℃). Set parameters such as Coulomb friction coefficient, forging temperature, forging rate, and forging deformation between different mutuals, and explore the most optimal forging plan. Using the true strain calculation formula, through the size of the forging, the method of setting the die reduction in the software to obtain the equivalent strain diagram of the single reduction; the setting of the temperature of the forging through the pre-processing module of the software is in the post-processing module , By selecting different cutting positions, obtain the equivalent strain diagram and unidirectional temperature streamline diagram of the forging after forging at different temperatures; set the die pressing rate through the software, and obtain the later metal flow velocity distribution diagram in the post-processing module.
