Improvement of Powder Recovery Device Based on Laser Additive Manufacturing
Laser additive powder manufacturing is a cutting-edge advanced manufacturing technology,but a large number of metal powders in the existing laser augmented powder manufacturing equipment can not enter the molten pool to participate in molding,resulting in waste.It is proposed to form a powder recovery device by adding centrifugal exhaust fan,powder suction nozzle,powder collector,two-stage vibrating screen,vibration source,primary vibrating screen,deposition substrate,molding box,laser powder feeding head,etc.The device can classify and screen the powder of the unmelted parts in the laser augmentation manufacturing,and directly feed the metal powder that meets the particle size requirements into the laser powder feeding device for recycling,so as to reduce the energy consumption of powder feeding and effectively improve the utilization rate of materials,then reduce the manufacturing cost of laser feeding.
