油箱壳体整体旋压工艺研究

Study on the Spinning Technology of Integral Tank Shell

用内旋压、无模摩擦收颈旋压方法，试制出整体旋压油箱壳体，减轻质量30％，减少焊缝70％。叙述了旋压工艺和旋压过程中出现的问题及解决办法。

By integral spinning, a tank shell was produced which showed deductions in weight and weld seam by30% and 70% respectively. The spinning process and its limitations are discussed in this paper.
