针对多楔轮的结构特征,结合实际生产提出成形工艺方案。利用DEFORM软件建立旋压增厚成形的三维刚塑性力学模型,基于数值模拟和正交试验获得试验数据,通过分析得出各工艺参数在增厚成形中对成形载荷的影响趋势及影响显著性顺序,并获得最佳工艺参数组合。优化结果经过CAE模拟和试验验证,增厚毛坯的成形质量得到提高,成形载荷大大降低,保护了旋轮和旋压设备。
According to the structural characteristics of multi-wedge wheel, the forming process is put forward according to the actual production. The three-dimensional rigid-plastic mechanics model of spinning and thickened forming was established by DEFORM software. The experimental data were obtained based on numerical simulation and orthogonal test. The influence trend of the forming parameters and the significant order , And get the best combination of process parameters. The result of the optimization is verified by CAE simulation and experiment, the forming quality of thickening blank is improved, the forming load is greatly reduced, the rotating wheel and spinning equipment are protected.
