Abstract：

A complex mold forging process of a complicated valve with asymmetrical ends and side walls was introduced including the rapid heating of raw materials, billets, removal of oxidation skin, mold forging, punching and forging conveying, mold cooling, lubrication and other complete process. Then, the key processes of the body in the multi-direction mold forging were analyzed by numerical simulation to search for the optimized forming method, and the results of numerical simulation were verified and corrected by the actual production verification. Therefore, the actual output of the body forgings fully met the design requirements, and the metal flow was continuous and complete. Thus, the overall mechanical properties were improved greatly comparing with the previous process, and the whole process could save labor about 80% and the subsequent metal cutting allowance about 70%.
