摘要
为满足高性能金属材料激光增材制造对稳定气氛环境的需求,对大型送粉式激光增材制造设备中的大容器气氛保护环境系统进行设计与研究。结合传统的惰性气体环境形成特点,设计金属材料激光增材制造气氛保护环境系统,用ANSYS软件对系统的核心部件进行了稳定性、可靠性模拟计算分析,同时优化了惰性气体环境形成的工艺过程,并进行实验测试验证。验证结果表明:该系统大幅提高了气氛保护环境的形成效率,降低了使用成本,突破了大容积气氛保护环境快速形成与保持技术,可为后续的高性能金属构件成形工艺研究提供快速、稳定的惰性气体环境。
For meeting requirements of high performance metal material laser additive manufacturing for stable atmosphere requirements, design and research on large-scale atmosphere protection environment system in large-scale powder-feeding laser additive manufacturing equipment. Based on the characteristics of the traditional inert gas environment, design the metal material laser additive manufacturing atmosphere protection environment system, use ANSYS software to carry out table and reliable simulation calculation analysis on system core, and optimize the technique process of inert gas environment formation and verify it by test. The verification test results show that the system can greatly improve the formation efficiency, decrease the cost, and improve the large-scale atmosphere protection environment fast formation and protection technology, which provides a fast and stable inert gas environment for the research of the forming process of high-performance metal material laser additive manufacturing.
