| 摘 要： | 喷射成形技术可以制备出高性能、高质量的工业锭坯,对工业的发展具有重要影响。雾化喷嘴系统是喷射成形装置的核心,喷嘴扫描运动方式对锭坯的均匀沉积有着重要的作用。本文以锭坯均匀沉积为目标,提出了基于凸轮驱动的参数可调的喷嘴扫描方式,建立了喷嘴分阶段变速扫描过程,确定了凸轮形状,对锭坯沉积轨迹进行了仿真并做了分析。最后用喷射成形实验对喷嘴分阶段变速扫描进行了验证,表明了其正确性。 |

| Abstract: | Spray forming technology can prepare high performance,high quality industrial ingot,has an important effect on industrial development.Atomizing nozzle system is the core of spray forming device.The movement way of nozzle has important influences on uniform deposition of billets.Based on the goal of well-distributed deposition of billets,phase-changeable variable scanning of nozzle drived by cam was put forward.And a cam mechanism that its parameters were changeable was designed,so that it could spray different diameter billets,equations of each phases and the outline of the cam were established,also deposition track was simulated and analyzed.The nozzle variable scanning had been verified by spray forming experiments at last. |
| Keywords: | spray forming cam-driving phase variable scanning uniformity |
