Multi direction die forging is a kind of precision forging technology for die forging on the multi direction die forging hydraulic press. Its deformation is essentially the combination of extrusion and die forging, mainly extrusion. Compared with ordinary die forging and split die forging, multi-directional die forging has the following technical and economic characteristics:
1. It can form forgings with complex structure and shape, significantly improve material utilization and reduce machining time;
2. The streamline distribution of forgings is reasonable, which is helpful to improve their mechanical properties;
3. Most small forgings usually do not need pre forging and can be formed only by heating once;
4. Expand the application scope of die forging technology to materials with narrow temperature and low plasticity;
5. The die has simple structure and long service life, which is conducive to reducing the cost of forgings.
