摘要
主要介绍了90°推制大口径弯头设计及成形的工艺过程、变形特点,分析了推制大口径弯头成形过程中金属的流动规律以及弯头内外弧壁厚与设计强度的关系。
Introduce the technology process of design and forming about 90 degree heavy calibre elbow、and it's feature of deformation, analyze the metal flowing rule and the relations between the wall thickness of inside -outside arc and the design intensity during the forming process of pushing heavy calibre elbow.
