摘　　要：以7022铝合金连杆毛坯件为研究对象,采用数值模拟技术研究其模具锻造成形过程,介绍锻造工艺路线,模拟预锻和终端阶段的各项工艺参数,得到了合适的工艺参数。结果表明,预锻阶段,坯料预热温度过高和锻压速度过快会导致坯料出现过烧现象;终端阶段,降低摩擦系数和锻压速度可以有效降低成形载荷。Taking the 7022 aluminum alloy connecting rod blank as the research object,the forging process of the die is studied by numerical simulation technology,the forging process route is introduced,the technological parameters in the pre-forging and terminal stages are simulated and the appropriate process parameters are obtained.The results show;that high preheating temperature and fast forging speed can lead to overburning of billet in the pre-forging stage.In the terminal stage,reducing the friction coefficient and forging speed can effectively reduce the forming load.
