摘要
本文根据大型储水、油球罐的实际受力情况提出了变厚度球罐的整体无模成形工艺,并通过试验获得了成功。本文对该工艺的可行性进行了试验探讨;对壳体的结构设计、材料选择、工艺参数、试验测试方法进行了研究;并对壳体的应变分布、胀形前后的壁厚分布及直径变化进行了测量,指出了变厚度球壳的应用前景。
In order to overcome the difficulty of manufacturing large-scale spherical vessels with dieless forming, a new kind of shell with special structure is put forward in this paper, and props have been welded on petals before deformation of the shell. A special process is also advanced to decrease two-faced angle between petals so as to overcome the difficulty of deformation of the zone between two petals on the equator line. The dieless forming process of the shell is studied in the paper, and the strain distribution, diameter variation and the displacement of the props under different friction condition are measured and analysed, It is feasible to manufacture the shell with dieless forming, and it also has high economic value, which has provided technological basis for manufacturing large - scale spherical vessels with dieless forming.
