摘要：

在简要介绍中重型高端商用车前桥部件的结构特点和功能以及湖北三环锻造有限公司、湖北三环车轿有限公司两家企业的基本情况的基础上，介绍了绿色锻造的技术内涵，并着重论述了实现绿色锻造的几项关键技术措施：建立清洁环保型锻造车间；研发前轴与转向节轻量化结构及小飞边精锻成形工艺，通过大幅节材，进而实现大幅节能、减排；建立智能自动化精锻生产线，大幅减小现场操作工的数量；实现对精锻工艺流程与加热温度密切相关环节的精确控制；热锻模3D打印制造与再制造，通过显著节能而改善环保。实践表明，这些措施通过节能降耗及环保进而体现绿色锻造，行之有效，所提出的用于实现绿色锻造的技术措施对于锻造生产企业具有重要参考意义。

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.
