Powder sieving device suitable for powder bed type metal 3D printing equipment

Abstract

The invention discloses a powder sieving device suitable for powder bed type metal 3D printing equipment. The powder sieving device comprises a base; four first electric telescopic rods which are distributed at equal intervals are arranged on the upper surface of the base, and a worktable is arranged at the top ends of the first electric telescopic rods; and the upper surface of the worktable is provided with two supporting frames, and the upper surfaces of the supporting frames are provided with a powder sieving box. According to the powder sieving device suitable for the powder bed type metal 3D printing equipment, the structure is reasonable, practicability is high, secondary filtering is conducted through a first sieving plate and a second sieving plate, and the filtering effect is improved; and waste filtered by the first sieving plate can be collected and disposed through a waste box, the filtering effects and the filtering speeds of the two sieving plates are enhanced through asecond electric telescopic rod, a third electric telescopic rod and servo motors, filtered metal powder is advantageously collected and disposed through a collecting barrel, moving and braking of thepowder sieving device are facilitated through universal wheels and a brake, and the powder sieving device is suitable for using and popularizing.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a powder sieving device suitable for powder bed metal 3D printing equipment.

[0002] 3D printing is a common name for additive manufacturing technology. It is a technology to manufacture solid parts by accumulating materials layer by layer through data. Compared with traditional material removal technology, 3D printing technology can even form parts with complex shapes, with high forming accuracy and material saving. Among them, laser selective melting, laser selective sintering and electron beam selective melting are the representative technologies of powder bed metal 3D printing. The materials are mainly powder materials. The molding powder in the printing field can be recycled, which is a green manufacturing that saves materials. technology, but some impurities will be produced during the manufacturing process, and these impurity clumping blocks will adversely affect the subsequent printing and molding products, making the molding quality worse. Most of the traditional sieve powders are filtered through simple filters, and the filters Do not change, only use the same filter for different powders, resulting in waste of powder, and mixing of different powders, which leads to poor molding quality, more impurities, and certain defects and limitations. For this reason, We propose a powder sieving device suitable for powder bed metal 3D printing equipment

But this device structure is simple, and practicability is relatively poor, is not suitable for popularizing and using
