| Abstract: | The paper introduced the speciality of super length_diameter ratio thick wall steel pipe part_shaping technology and the mould structure. The author designed a springy rigidity punch, making it possible for the expanding_shape by rigidity punch to achieve the effect of the expanding_shape by soft punch. There were three partial expanding_shape that adopted the technology process of forming separately. The punch was a combination of insert, making it convenient for partial exchange. |
