Problems solved by technology

The metal powder screening device for metal 3D printers passes through material boxes, slow motors, screw shafts, gears, chains, connecting pipes, coarse mesh plates, fine hole mesh plates, micro motors, cams, springs, and impurities The mutual cooperation between the tubes, although this method is convenient to sieve the metal powder, but the sieving effect of the powder sieving machine is not good, the metal powder is easy to gather in the powder sieving machine to reduce the screening efficiency, and it is inconvenient to prevent agglomeration The metal powder is crushed, and the powder sieving machine in the prior art is inconvenient to take out the unqualified metal powder

Abstract

The invention discloses basic shaft type metal 3D printing equipment which comprises a powder supplementing and scraping integrated device, a powder suction device and a powder screening machine. A drawer of the powder supplementing and scraping integrated device communicates with a powder suction port of the powder suction device through a powder feeding pipe, a discharging pipe of the powder suction device communicates with a feeding cylinder of the powder screening machine through a powder feeding pipe, and a vacuum conveyor is arranged on the powder feeding pipe. The basic shaft type metal3D printing equipment is simple in structure and convenient to use, the powder supplementing and scraping integrated device is adopted for printing, the printing effect is good, printed metal powdercan be recycled conveniently, the metal powder can be recycled or the metal powder at a certain position can be sucked into the powder screening machine to be screened, and temporary storage, conveying, screening, storage and the like can be conducted.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a shaft-based metal 3D printing equipment. Background technique [0002] Metal 3D printing technology has the advantages of personalized design, fast forming, and short manufacturing cycle. It is very suitable for the manufacture of small batches, personalized metal parts with complex surfaces and internal structures. In the process of 3D printing metal powder, high energy density The laser directly acts on the metal powder, and the laser scans quickly to make the metal powder melt and condense quickly. [0003] The quality requirements of important parts on aerospace equipment are very high. When adding powder, if there is a cavity in the powder, it will be reflected in the inner wall of the product. The need to focus, unevenness will cause the laser to fail to melt the metal particles correctly, and will cause fatal defects in product quality. The existing SLM me...
