摘要：

针对2219铝合金数铣网格壁板，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，运载火箭贮箱壁板从壁厚、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1.1~1.4 mm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隙值均不超过1.5 mm。

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 roll bending after CNC milling grid, and the filling 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 hardness is a better filling material than the rubber 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.
