Abstract : focused on the metal plastic forming of valve bodies for power plant boiler , a new process named “ shear extrusion ” is described in this paper . the numerical simulation analysis is carried out by using the 3 - d deform software to predict the distribution of velocity , stress , strain and temperature fields during the forming process and the flow law of metal . then the numerical simulation results are testified by simulative experiment . finally , large - size valve bodies have been successfully formed by the screw press 文摘:针对电站锅炉用大型截止阀体的制造新工艺? “剪切挤压” ，利用数值模拟的方法对剪挤工艺进行研究，得到了成形过程中速度、应力、应变及温度场等的分布及金属流动规律，并通过物理模拟实验进行了验证，进而为获得阀体剪挤制造的最佳成形工艺参数提供可靠依据。
The stress and working pressure on teeth of the staged nut in screw presses has been studied by fem method which proves that using staged nut in screw presses is helpful for improving the non - uniform distribution of stress and working pressure on the teeth and extending the working life of the screw 摘要采用了有限元法对滑动螺旋压力机的阶梯式螺母进行了受力分析，研究了螺母螺牙应力及螺牙工作面的接触压力，并将阶梯式螺母与普通螺母进行对比，认为螺旋压力机中使用阶梯式螺母有利于改善螺牙牙根应力轴向应力分布不均和螺牙工作面的接触压力分布不均的情况，从而提高螺旋工作寿命。
