摘要：针对2219错合金数铣网格壁板，采用直接滚弯成形和填料滚弯成形两种成形方法进行研究。结果表明，运载火箭贮箱暨板从厚、板宽、网格形式方面均存在很大差异；网格壁板的成形可以采用先数铣网格后直接滚弯成形的方案加工；填料滚弯工艺方法不适于成形外网格形式壁板零件，但可以成形内网格形式壁板；采用硬度更高的PE塑料板作为填充料明显优于橡胶填料；通过采用PE塑料板作为填料，滚弯后的内网格壁板母线直线度在1.1-1.4mm范围内；通过采用多道次小进给量直接滚弯成形工艺，三角网格壁板和四边形网格壁板的型面间除值均不超过1.5mm。

Abstract : For aluminum alloy 2219 grid panel by CNC milling , the direct roll bending and the filling roll bending process were studied. The results show that there are great differences between the tank wall of a launch vehicle in thickness, plate width and grid. However, the grid panel is formed by direct moll bending after CNC milling grid, and the flling roll bending process is not suitable for forming outer grid panel, but it can form the inner grid panel, Furthermore, PE plastic plate with a larger handlness is a beter filling material than the nubber filler, and the bus straightness of the inner grid panel is between 1. 1 and 1. 4 mm after roll bending by PE plastic plate as filler material. In addition, the surface gap between the triangular grid panel and quadrilateral grid panel is not more than 1. 5 mm by direct roll bending process with multi-pass and small feeding,

壁板的网格结构形式存在很大的差异。在航天领域中，运载火箭贮箱中筒段壁板多为网格形式的壁板，网状筋条内外形式均有，且筋板厚度较大[1-2]
传统贮箱壁板网格均为化铣结构（图1），化铣工艺具有化铣圆角大、废重多、环境污染等缺点，不利于箭体减重[3)。随着运载火箭装配精度和减重要求的提高，为保证箭体可靠性、减轻结构重量、提高有效载荷，对壁板网格尺寸精度和减小筋条根
