摘　　要：利用静水应力区切应力力学模型,对管板锻件在镦粗成形过程中的工艺参数加以控制,优化设计了小方砧进行局部镦粗,改善毛坯内部的应力状态,避免刚性区相遇产生附加的剪切变形,保证锻件的内部质量。By mechanical model of shear stress at static water stress zone, technical parameters of tube sheet forgings in the process of upsetting formation have been controlled, meanwhile local upsetting has been conducted by smaller anvil after design optimization to improve stress situation inside of the blank in order to avoid attached shearing deformation resulted from rigid zones meeting, whieh could guarantee inner quality of forgings.
