Structure Design and Static Strength Analysis of Axial Ring Rolling Machine

  • 摘要: 端面碾压机是针对航天航空中所应用的复杂异形截面环件而专门设计的特种塑性成形设备。首先分析了端面碾压机的工作特点及其结构设计,然后对设备的机架、导柱、锥辊轴及压辊保持架等关键部件进行了静力学仿真,分析了高负荷工况下的应力分布和结构变形特性,校核了锥辊轴承选型寿命,以验证端面碾压机结构设计的正确性和合理性。结果表明,设备整体结构强度满足要求,但在高负荷下,轴承等零部件设计寿命需进一步提升。

     

    Abstract: The axial ring rolling machine is a special plastic forming equipment especially designed for the complex shaped cross-section ring parts applied in aerospace and aviation. The axial ring rolling process adopted by this equipment is a structural design combining a single cone roller and an annular mold, which can obtain high-precision shaped ring parts by applying axial load to the ring parts and realizing continuous and progressive plastic forming. Firstly, the structural design of the machine and its working characteristics are introduced, and then static simulation is carried out on the key parts of the machine, such as guide column, frame, drive roll shaft and holding roll cage, etc. The stress distribution and deformation characteristics under high load conditions are analyzed, and the life span of the drive roll bearings is calibrated to verify the correctness and reasonableness of the structural design of the equipment. The results show that the overall structural strength design of the machine meets the requirements, but under high load, the life of bearings and other components needs to be further improved.
