本文应用画法几何的基本原理,对大型球罐展开下料问题进行了初步探讨,提出了关于不可展曲面一球面展开的新观点,对大型球罐展开下料提出了新方法。特别针对混合式结构排板的球罐,我国过去没有制造过,本文对此在探讨的基础上,为我国今后制造该种球罐提供了一定的理论依据,并在理论探讨的基础上设想了新的工艺方法,为结合生产实际打下一定的基础。
In this paper, the basic principles of the geometry of the painting, the large-scale spherical tank unwinding the issue of a preliminary study, put forward on the inextensible surface of a spherical expansion of the new point of view, the large spherical tank unwinding proposed a new method. Especially for the tank with mixed structure row plate, our country has not been produced in the past. Based on the discussion above, this article provides a theoretical basis for the future manufacture of this type of tank. Based on the theoretical discussion, The new technology, in order to lay a solid foundation for the production.
