| 摘 要： | 文摘为了生产出质量合格的叶片,针对TC4合金叶片的成形特点,为其制订了相应的热模锻成形工艺。同时采用基于有限体积的材料成形模拟技术,对TC4合金叶片热模锻过程进行了模拟,分析了坯料成形过程中的充填情况、应变场、应力场及终锻温度场的分布规律。模拟结果表明:锻件轮廓清晰,模具型腔充填完整,未出现充不满或折叠等锻造缺陷。实际生产出来的叶片经理化检测和外观检查,质量符合要求,制定的工艺方案合理,可以满足TC4合金航空风扇转子叶片的成形质量要求。 |

| Abstract: | In order to produce qualified blade,hot forging forming technology was developed according to the forming features of TC4 blade.At the same time,numerical simulation of airfoil blade during hot forging was carried out to analyze the filling of die and the distributions of strain,stress and temperature.The simulation results showed that the die cavity's filling was good without any forging defect.The quality of TC4 blade can meet the requirement after physical testing,chemical analysis and visual examination.So,hot forging forming technology can meet the production requirement of TC4 airfoil blade. |
| Keywords: | TC4 titanium alloy Airfoil blade Hot die forging Numerical simulation |
