Abstract：

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.
