以凹弧辊沿凸形模表面进行滚辗（又称擀压）是将滚弯和辗弯综合为一体的双向弯曲成形方法，属于增量成形范畴。其成形思路独特，并具有滚平皱纹、辗匀厚度、省力省料等优点。本文在实验研究和已成功地制成φ３００ｍｍ半球壳的基础上，提出滚辗成形半球壳的新工艺。同时，介绍了其成形的原理、工艺过程、特点、实验分析，并对其成形的变形机制做了定性分析。 With concave arc roller along the convex surface of the mold rolling (also known as rolling pressure) is a combination of rolling and rolling Bend two-way bending forming method, belonging to the incremental forming. Its formation of unique ideas, and has rolled flat wrinkles, rolling uniform thickness, saving energy and other advantages. Based on the experimental research and the successful fabrication of the φ300mm hemispherical shell, a new technique of forming the hemispherical shell by rolling is proposed in this paper. At the same time, the forming principle, technological process, characteristics and experimental analysis are introduced, and the deformation mechanism of forming is analyzed qualitatively.
