Abstract：

For the low efficiency of aviation blade precision forging die designing and the difficulty to determine some design parameters in China, a parametric CAD forging system was developed based on the analysis of aviation blade precision forging technology, and the automatic generation of aviation blade precision forging die and forging billet was realized. So the blade die design automation was improved. Furthermore, the whole precision forging process was simulated by Deform-3D, and the stress distribution of forging and die, transverse clamping die force and die wear were analyzed under different design parameters. Then, the design parameters advantageous to the blade forming and the die life prolonging were obtained, and the parameter design rules were optimized. Finally, the forging experiments were carried out, and the geometrical dimension accuracy of forging was analyzed, which provided a theoretical guidance for selecting parameters in the precision forging die design of aviation blade.
