摘要: 为了得到表面粗糙度低的立面变径回转体,采用中空激光光内同轴送粉技术进行立面堆积的方法,着重对中空激光立面堆积的优点以及激光光头姿态、光头提升量z、激光功率对立面堆积成形件表面粗糙度的影响进行了理论分析和实验验证。在立面堆积过程中,激光光头始终保持与熔道表面垂直,同时对提升量z、激光功率进行实时控制,最终得到表面光滑的立面回转体成形件,其粗糙度Ra为0.497m~2.163m;Rz为1.992m~7.447m。结果表明,该方法在立面堆积方面具有适用性,可以得到表面粗糙度低的成型件。

Abstract: In order to obtain a rotator with low surface roughness and variable radii, based on the technology of laser cladding manufacturing process with coaxial inside-beam powder feeding, the advantages of coaxial inside-beam power feeding accumulation and the influence of the posture, increment in z axis (z) and laser power of the laser head on the surface roughness were analyzed theoretically and verified experimentally. In the accumulation process, laser head was kept perpendicular to the molten surface, z and laser power were effectively controlled. Finally, a fine rotator was obtained with low roughness, i.e.,Ra=0.497m~2.163m;Rz=1.992m~7.447m. Experimental results show that this method is applicable for laser accumulation on vertical surfaces and the molding parts have lower roughness.
