Numerical simulation-based forging forming analysis method for 20CrMnTi rear axle gear

The invention discloses a forging forming analysis method for a 20CrMnTi rear axle gear based on numerical simulation. The forging forming analysis method specifically comprises the following steps that firstly, a cold-state forge piece blank and a hot-state forge piece blank of a forge piece are designed according to a product; secondly, a pre-forging die and a forming die are designed according to the hot-state forge piece blank; 3, performing numerical simulation by using finite element simulation software to perform simulation analysis; and fourthly, the forming state of the forge piece is analyzed and optimized. The invention relates to the technical field of machining processes of basin tooth forgings, in particular to a numerical simulation-based forging forming analysis method for a 20CrMnTi rear axle gear, and by applying the method, raw material consumption is reduced, and the production cost is reduced. 本发明公开了一种基于数值模拟的20CrMnTi后桥齿轮的锻造成型分析方法，具体包括下列步骤：步骤一、根据产品设计锻件的冷态锻件毛坯和热态锻件毛坯；步骤二、根据热态锻件毛坯设计预锻模具、成型模具
