摘要：

随着我国航空航天技术的飞速发展，对大型零部件的加工要求越来越高，旋压成形薄壁回转体零件的优势越来越明显，因此对大型旋压设备的需求越来越迫切。详细分析了目前研制大型数控强力旋压设备的技术难点，并给出了相应的解决方案。该项目研制的大型数控强力旋压机加工零件直径可达Φ2600 mm，主轴转速20～100 r·min-1，回转工作台直径可达Φ2800 mm。试验结果表明，在该设备上旋压成形零件的壁厚差仅为(3±0.06)mm，机床各项技术指标达到或超过了同期国际先进水平。

With the rapid development of aerospace technology, the processing requirements of large parts are moving up, and the advantages of spinning technology to form the thin-walled rotary parts are more obvious. Consequently, the demands of large-scale spinning equipment become more and more urgent. The technical difficulties in the development of large NC spinning machine were analyzed in detail and the corresponding solutions were given. By the NC power spinning machine developed in the project, the diameter of formed parts can reach Φ2600 mm, the spindle speed is among 20-100 r·min-1 and the diameter of rotary worktable is up to Φ2800 mm. The test results show that the wall thickness difference of product formed is only (3±0.06)mm, and the various technical indexes of machine reaches or exceeds the international advanced levels.
