中文摘要: |
激光宽带熔覆侧向送粉喷嘴在激光宽带熔覆中起着重要的作用。文章设计了一种激光宽带熔覆侧向送粉喷嘴,
介绍了喷嘴的结构特性以及工作原理,通过旋转轴杆调节挡条的移动实现粉末出口宽度可调。对喷嘴进行送粉实验,通
过在喷嘴下端放置接粉槽收集粉末,计算粉末的有效利用率,实现粉末利用率在50%左右。 |
英文摘要: |
Wide-band lateral powder nozzle plays an important role in broad beam laser cladding. A kind of lateral
powder nozzle in broad beam laser cladding was designed. It introduced the structure of the nozzle and its operating
principle. It could realize the width of feeding powder changeable by rotating shaft lever to adjust the movement of
barrier strip. A feeding powder experiment was conducted on the nozzle. A groove to collect the powder was placed
under the nozzle and computed the effective utilization of powder. It realized the powder using efficiency at about 50
percent. |
