Abstract

The invention discloses a device for preparing spherical metal powder through laser-assisted grinding, and belongs to the field of material processing.The device comprises an atmosphere chamber, a collector, a workbench, a grinding motor and a laser head, the laser head, the grinding motor, the workbench and the collector are all arranged in the atmosphere chamber, and the workbench is connected with a workbench driver; the grinding motor is connected with a grinding tool bit, the grinding tool bit is arranged above the workbench, and a metal block is placed on the workbench; a collecting opening is formed in the side, close to the workbench, of the collector, and the center of the collecting opening and the contact position of the metal block and the grinding tool bit are arranged on the same straight line. And an optical fiber is connected above the laser head. Metal blocks are crushed into fine powder particles through a low-energy efficient grinding machining method, then high-temperature powder is heated and melted into liquid drops through laser beams, irregular particles formed through grinding are converted into spheres, the structure is simple, operation is convenient, and efficient and low-consumption machining of spherical metal powder is achieved.

Description

technical field [0001] The invention relates to the technical field of material processing, in particular to a device and method for preparing spherical metal powder by laser-assisted grinding. Background technique [0002] With the rapid development of metal additive manufacturing technology, the demand for metal powder is increasing, and it is urgent to develop a convenient and economical spherical metal powder preparation technology. At present, the main preparation methods of spherical metal powder are gas atomization method, water atomization method, ultrasonic atomization method, rotating electrode atomization method, and combined powder making methods. The basic principle of spherical metal powder preparation is to melt the metal through a certain form of heat source, and then use a certain form of energy to disperse the liquid into fine droplets. As a new type of heat source, laser has the advantages of high energy and time resolution, and it is more and more widely...
