Problems solved by technology

However, the elasticity of the metal sheet is relatively large. When the metal parts are thermally expanded and warped, although the parts will not be damaged, it will produce more serious elastic powder and dusting phenomenon, which will cause a pit on the powder coating surface. , affecting the powder quality

Abstract

The invention discloses an adsorption type surface contact flexible powder spreading device of a selective laser melting molding system. The adsorption type surface contact flexible powder spreading device of the selective laser melting molding system comprises a movable bracket A, a negative pressure channel device A, a flexible powder spreading brush, a mounting bracket, a negative pressure channel device B, a movable bracket B; the mounting bracket is internally provided with a negative pressure cavity; the movable bracket A and the movable bracket B are fixed at the two ends of the mounting bracket respectively; an adsorption groove and a powder storage groove are formed in the bottom part of the mounting bracket; the upper plane of the flexible powder spreading brush is adsorbed inside the adsorption groove; a lateral clamping groove of the flexible powder spreading brush is overlapped with the side surface of the adsorption groove; the powder spreading plane of the flexible powder spreading brush protrudes out of the adsorption groove; the negative pressure channel device A and the negative pressure channel device B are mounted on the two ends of the mounting bracket respectively and are communicated with the negative pressure cavity. The adsorption type surface contact flexible powder spreading device of the selective laser melting molding system not only can spread the powder flatly, but also can avoid powder flying phenomenon when a molding surface of a part is uneven. Meanwhile, due to the adoption of the adsorption type mounting way, the adsorption type surface contact flexible powder spreading device is convenient to detach and mount, and has the advantages of good powder spreading effect, use convenience and the like.

Description

technical field [0001] The invention relates to the field of parts forming and manufacturing in a laser selective melting forming system, in particular to an adsorption type surface contact flexible powder spreading device of a laser selective melting forming system. Background technique [0002] Additive manufacturing is a new type of manufacturing technology, which is currently developing rapidly as a supplement to traditional manufacturing technologies. Selective Laser Melting (SLM) technology has become the most mainstream additive manufacturing technology for metal parts because it can directly form metal parts with dense structure and metallurgical bonding. [0003] The laser selective melting molding process is as follows: the powder spreading device spreads a layer of metal powder on the molding cylinder, the laser beam is controlled by the computer, and according to the cross-sectional shape information of the molding, the powder is selectively scanned, so that the ...
