激光熔覆快速成形技术送粉喷嘴的研制

Develop of feeding nozzle for laser cladding rapid prototyping

本文针对激光熔覆快速成形技术对送粉喷嘴的要求,分析了已有用于激光熔覆和激光熔覆快速成形技术送粉喷嘴存在的问题,研制了一种在以激光束为中心轴的圆周方向均匀对称分布四个具有同轴汇聚气的双层送粉管的送粉喷嘴。实验研究表明,此送粉喷嘴可以满足激光熔覆快速成形技术对送粉喷嘴的要求。

This paper bases on requirement of laser cladding rapid prototyping for feeding nozzle, and analyses problems of existing feeding nozzle for laser cladding and laser cladding rapid prototyping, Developed a feeding nozzle which have four double - feeding pipes with co- axial shaping gas distributes on circle orientation of laser beam with uniformity and symmetry. Research shows this feeding nozzle can satisfy requirement for laser cladding rapid prototyping.
