Abstract：

Based on a brief introduction of the structural features and functions of front axle components for medium-heavy high-end commercial vehicles and the fundamental states of two companies, including Hubei Tri-Ring Forging Co.,Ltd. and Hubei Tri-Ring Auto Axle Co.,Ltd., the technical connotation of green forging was illustrated, and some critical technical measures to achieve green forging were discussed emphatically, including the establishment of clean and environment-friendly forging workshop, the research and development of front axle and steering knuckle light-weight structures and small flash precision forging processes which realized the large-scale energy conservation and emission reduction by significant material conservation, the establishment of intelligent automatic precision forging production line to reduce the number of field operators drastically, the precise control of steps closely related to process flow and heating temperature of precision forging, and the 3D printing manufacturing and remanufacturing of hot forging dies which improved the environmental protection by significantly saving energy. Engineering practices show that these measures are feasible and effective to achieve green forging by saving energy, consumption reduction and environmental protection, which have important reference significance to forging enterprises.
