摘　　要：基于某国产80 MN电动螺旋压力机,利用有限元模拟软件Deform-3D对某型号前轴锻造中的辊锻、压弯、终锻成形工序进行研究,分析了坯料经压弯后的等效应力,确定了压弯后的弯曲状态,确保其能够平稳放入终锻型腔中。借助Screw Press模块对终锻成形过程进行有限元模拟,分析了前轴锻造过程中的能量分配和力能关系,获得了终锻打击力变化曲线,得出终锻合模状态下前轴锻造所需的最小成形能量。实验结果显示:终锻打击力小于压力机的允许最大用力,且设定打击能量为额定能量的73%时,可以满足终锻设计需要,与模拟得出的70%额定能量相比,误差较小,说明模拟结果对实验有很好的指导意义。For a domestic 80 MN electric screw press,the processes of roll forging,press-bending and final forging in the forging of a certain model of front axle were studied by finite element simulation software Deform-3D,the equivalent stress of billet after pressbending was analyzed,and the bending state after press-bending was determined so that it could be put into the final forging cavity smoothly.Then,the final forging process was numerically simulated by Screw Press module,and the energy distribution and the force-energy relationship in the front axle forging process were analyzed.Furthermore,the change curve of the final forging striking force was obtained,and the minimum forming energy required for the forging of the front axle under the final forging and closing state was obtained.Experimental results show that the striking force of final forging is less than the maximum allowable force of the press,and when the set striking energy is 73%of the rated energy,it meets the requirements of the final forging design.Compared with the simulated 70%rated energy,the error is relatively small,indicating that the simulation results have good guiding significance for the experiment.
