摘要：

对轮旋压机对于超大型薄壁筒形件的柔性制造具有重要意义。开展了立式对轮新型旋压机的结构设计，采用Solidworks软件对各部件和整体结构进行有限元仿真，并进行结构设计优化。结果表明，该设备中各部件结构的最大位移量均小于0.15 mm，最大等效应力远低于所用材料的屈服强度，设备可以在给定载荷下安全工作。此外，机床框架增设加强筋，可以有效提高结构刚度和设备精度。在此基础上，最终制造出径向承载60 kN和轴向承载150 kN的立式四对轮新型旋压机，并成功地进行了铝合金筒形件的对轮旋压工艺实验。

The counter-roller spinning machine is of great significance for the flexible manufacturing of ultra-large thin-wall cylindrical workpieces. Therefore, the structure design of vertical counter-roller spinning machine was conducted, and the structures of each component and the whole machine were simulated by software Solidworks. Then, their structures were optimized. The results show that the maximum displacement of each component is smaller than 0.15 mm, and the maximum equivalent stress is much lower than the yield strength of selected materials. Therefore, the machine can safely work under the given load. In addition, the stiffeners are added to the spinning machine frame to improve the structure stiffness and machine precision. Finally, a new vertical counter-roller spinning machine with four pairs of rollers were manufactured which could carry 60 kN in the radial direction and 150 kN in the axial direction, and the counter-roller spinning experiment of aluminium alloy cylindrical workpiece was conducted successfully.
