Abstract

The invention relates to a powder management system for SLM equipment. The powder management system is used for carrying out powder supply and processed powder collection on a powder laying system inthe SLM equipment. The powder management system comprises a frame for supporting the whole system, and further comprises a powder falling device, a powder storage and conveying device and a powder collecting device. The powder falling device is connected to the upper end of a work area of the powder laying system, the powder collecting device is connected to the lower end of the work area of the powder laying system, and the powder storage and conveying device is connected with the powder falling device and the powder collecting device. The powder storage and conveying device conveys powder through a turbine fan set. Compared with the prior art, the powder management system can achieve automatic powder conveying, secondary powder adding and secondary powder collection are convenient, and the advantages of being stable, reliable, high in work efficiency and the like are achieved.

Description

technical field [0001] The invention relates to the field of SLM equipment, in particular to a powder management system for SLM equipment. Background technique [0002] Selective Laser Melting (SLM) technology is a technology that uses high-energy laser beams to directly irradiate metal powders to rapidly melt and cool and solidify them. It can be applied to single metal powders or mixed metal powders. . It can directly form metal powder into metal parts, and the density of parts is close to 100%. SLM technology has been widely used in aerospace, automobile manufacturing, military and medical industries. [0003] In the powder management system of the prior art, most of the powder feeding systems still need to rely on a certain amount of manpower, that is, the powder is artificially added to the powder tank, and then the powder spreading system controls the powder spreading; at the same time, there are still residual powder after printing. There is no good collection syste...
