Performing shot blasting and phosphorus saponification treatment to obtain a pre-forged piece; the pre-forged piece is subjected to precision forging forming, a closed forging technology is adopted for a precision forging die, flash-free forging is conducted, and vent holes are designed in the precision forging die; the surface of the workpiece subjected to normalizing treatment is subjected to sand blasting treatment, and the workpiece subjected to sand blasting treatment is subjected to rust-proof treatment, so that the rejection rate of products is reduced, the qualification rate of the products is improved, and the energy consumption is greatly reduced.
