以轿车旋锻半轴（M TS）为对象，对模具入口角度、模具精整段长度、模具-坯料-芯棒间摩擦系数、轴向拉力等关键参数与材料流动方式和锻造力之间的内在关系进行研究。研究结果表明，随着模具-坯料-芯棒间摩擦系数增大，中性面向模具出口端移动，且径向、轴向锻造力增大；模具入口角度增大时，中性面向模具出口端移动，旋锻力减小，轴向锻造力增加；模具精整段长度、轴向拉力增加时，中性面向模具出口端移动，且旋锻力增大，但轴向锻造力不变。提出了旋锻轴关键参数的制定准则，并以某轿车旋锻轴为例，给出了模具入口角度、模具精整段长度、摩擦系数、轴向拉力等关键参数。采用工艺试制和产品质量试验，验证了旋锻工艺参数制定准则的正确性和合理性。

The relationship between the key process parameters ,such as die inlet angle ,the length of finishing zone of tool ,the shear friction coefficient ,the axial force acting on blank ,the flow of the material and forging force were studied .The results show that with the coefficient of friction increases ,the neutral place moves towards the exit of the tool ,the axial and rotary swaging force increases ,with the die inlet angle increases ,the neutral place moves towards the exit of the tool ,the rotary swaging force decreases and the axial forging force increases ,with the length of finishing zone of tool or the axial force acting on blank increases , the neutral place moves towards the exit of the tool and rotary swaging force increases ,but the axial forging force keep constant ;Guidelines are developed to determine the critical process parameters during the manufacturing of a Monobloc Tube Shaft (MTS) . By using the guidelines ,taking M TS as an example ,the value of the die inlet angle ,the length of finishing zone and the shear fric-tion coefficient was proposed .After the experimental manufacturing with these process parameters ,the experimental results dem-onstrate the correctness and rationality of the guidelines for determining the value of process parameters .
