| 中文摘要: |
| 介绍了适合于制造铝合金复杂曲面薄壁件的液压成形技术，包括充液拉深、可控径向加压充液拉深和液体凸模拉深。由于充液拉深能提高成形极限，适合于制造铝合金复杂型面零件。可控径向加压充液拉深通过径向压力向内推料，进一步提高了成形极限，适合于成形大高径比筒形件。液体凸模拉深适合于获得深度较大、形状复杂、尤其底部具有小过渡圆角的复杂形状零件。 |
| 英文摘要: |
| Hydro-forming for aluminum alloy complex-shaped sheet component is introduced, including hydro-mechanical deep drawing, hydro-forming with radial controllable pressure and drawing of fluid punch. Due to an enhanced forming limit, hydro-mechanical deep drawing is suitable for manufacturing complex-shaped components. Pushing the rim of blank by fluid pressure, hydro-forming with radial controllable pressure can improve forming limit further, and suitable for producing large height-diameter ratio cups. Drawing of fluid punch is suitable for making deeper, complex-shaped components with small radius at the bottom. |
