摘　　要：根据辊锻设计要求,论述了汽车前轴辊锻件的弹簧座截面、工字型截面、两端拳头截面各道次变化规律;在各道次变化过程中,依据各截面的尺寸参数变化对辊锻模具进行精确设计并选择合理的坯料,以保证坯料能够充满模具型槽。应用Deform-3D软件对辊锻模具模型进行模拟分析,模拟结果与实际生产结果相吻合,进一步验证了辊锻模具设计的准确性和可靠性。该文的论述对前轴辊锻模具的精确设计及辊锻件的生产提供了理论参考依据。According to the roll-forging design requirements, the changing rule of roll-foging＇s spring section, H- shaped cross section and fist section ends was discussed. In each step change process, according to the cross-section＇s parameters, the roll forging die could be precisely designed, meanwhile, the reasonable billet was selected to ensure that the die cavity could be fully filled. Then, Deform-3D finite element simulation software was used to analyze the roll forging process. The simulation results coincided with the actual production results, which further validate the ac- curacy and reliability of the roll forging die design. The results provide theoretical guidance on the front axle roll forg- ing die and roll forging precision design.
