摘　　要：摆动辗压是一种局部成形的加工方法,特别适用于盘类及薄扁状零件的成形。摆动辗压机的摆头运动轨迹较为复杂,该文针对多叶玫瑰线运动轨迹中的摆头在交变成形力的作用下会导致摆头轴断裂,较深入的分析和研究双偏心套摆辗机摆头的多叶玫瑰线运动轨迹特点,根据摆头运动原理,建立摆头运动方程,提出并分析摆头新型多叶玫瑰线运动轨迹的形成与规律,改善摆头受力状况。研究工作不仅可以解决通常一些设计中摆头在交变成形力的作用下导致的摆头轴断裂,而且对于改进传统的摆头结构、设计新型摆辗机和拓展摆辗成形工艺提供了理论指导。Orbital forming is a processing method of local forming, especially suitable for disc-type parts and thin flat shaped parts forming. Trajectories of orbital forming press head is more complex, this article focuses on orbital head shaft fractures under the action of the alternating force by multi sheet trajectories, more in-depth analyzes and researches on multi sheet trajectories features of double eccentric orbital forming press head, according to orbital head movement principle, builds its motion equations, proposes and analyzes the formation and regular pattern of the new multi sheet trajectory, improves the orbital head force status. Research work provides theoretical guidance for improving the structure of traditional orbital head, designing new orbital forming press, expanding orbital forming process.
