摘要：

针对航天大型铝合金环筒件的制造需求，开展了6000 t锻造液压机设备的研制工作。首先，对设备主要参数、主机结构与核心功能进行了详细设计，确定了四柱“拉杆预紧组合框架”式结构；通过引入速度闭环控制理论、优化滑块和立柱导向结构以及移动工作台的定位方式，解决了自由锻造与模锻功能兼容的难题；通过开发预冲+终冲的快速冲孔模块，设计了3个工位的移动工作台，提高了环筒件的制孔效率。其次，分析和确定了锻造工艺的主要内容，开展了工装模具设计与制造工作。最后，进行了产品的工程化试制，验证了设备及工艺的可行性。结果表明，6000 t锻造液压机可以满足环筒件的生产需求，对减少锻造火次与工装更换次数、提高生产效率起到较大的作用。

For the manufacturing demand of large aluminum alloy ring and cylindrical workpiece in aerospace, the development work of 6000 t forging hydraulic press was carried out. Firstly, the main parameters of equipment, the structure of main body and the core functions were designed in detail, and the four-column “tie rod pretension assembled frame” structure was determined. By introducing speed closed-loop control theory, optimizing guide structure of slider and column and positioning mode of mobile workbench, the problem of compatibility between free forging and die forging was solved. Through the development of quick punching module for pre-piercing and final-piercing, three-station mobile workbench was designed, and the piercing efficiency of ring and cylindircal workpiece was improved. Secondly, the main contents of forging process was analyzed and determined, and the tooling and dies were designed and made. Finally, the engineering trial production was carried out, and the feasibility of equipment and process was examined. The results show that the 6000 t forging hydraulic press can meet the manufacturing demand of ring and cylindrical workpiece which plays a great role in reducing forging heating times and tooling replacement times and improving production efficiency.
