Abstract

The invention discloses a powder spreading device, and relates to the technical field of additive manufacturing. The powder spreading device comprises a scraper frame, a drive motor, a flexible scraper and a coupler. The flexible scraper comprises a scraper core and a scraper sleeve; the scraper core is of a cylinder structure; the scraper sleeve is of a hollow cylinder structure; the scraper coreis sleeved with the scraper sleeve; the flexible scraper and the drive motor are installed on the scraper frame; and a rotary shaft of the drive motor is connected with one end of the flexible scraper through the coupler. The drive motor is connected with the flexible scraper. after the part of the flexible scraper is abraded, the drive motor can drive the flexible scraper to be rotated by any angle, the contact position of the flexible scraper and powder is adjusted again, the part, not abraded, of the flexible scraper makes contact with the powder, the flexible scraper can be continue to beused, the utilization rate of the scraper is improved, the drive motor controls the position of the scraper, a cabin door does not need to be opened, formed parts are not oxidized, and the printing quality is ensured.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a powder spreading device. Background technique [0002] Metal laser 3D printing technology is also called additive manufacturing and rapid prototyping technology. Metal parts formed by metal laser 3D printing have the advantages of high density, high strength and low surface roughness, and can reduce the initial investment of personalized complex parts Cost and save manufacturing time, so it is widely used in automotive, aerospace, marine, jewelry, medical and other fields. [0003] The forming principle of metal laser 3D printing technology is to use 3D data as a template, first spread a layer of metal powder evenly on the forming substrate, use the high-energy laser beam to melt the metal powder according to the slicing data of the forming part, and then spread it on the forming substrate. A layer of metal powder, and then melt the metal powder according to the...
