Problems solved by technology

After feeding the powder from the powder feeding cylinder, during the powder spreading process of the powder spreading device, a lot of powder will enter the recovery tank before entering the forming area, resulting in a decrease in the utilization rate of the powder, and the scraper is in the process of scraping the powder in order to ensure the laying. The powder is on a horizontal plane, and the length of the powder needs to be extended. Each time the molding needs to prepare metal powder that is many times larger than the volume of the workpiece, the follow-up recycling work is very troublesome, resulting in a waste of man-hours

Abstract

The invention discloses selective laser melting equipment and relates to the field of elective laser melting equipment. The elective laser melting equipment comprises a scraper device, a powder feeding device, recovery devices and a selective laser melting table, wherein the recovery devices are arranged on two sides of the selective laser melting table; the scraper device is arranged above the selective laser melting table; and the powder feeding device is arranged right above the selective laser melting table. By adoption of the selective laser melting equipment disclosed by the invention, the powder utilization ratio can be improved; the scraper device is equipped with double scraper plates used for spreading powder to and fro, so that the powder spreading efficiency can be guaranteed;through the recovery of redundant powder, not only can a complete plane be obtained, but also the length of the selective laser melting table can be reduced, and then the powder consumption and the amount of recovered powder can be reduced; and a traditional powder feeding mechanism is arranged on one side of the selective laser melting table, however, the powder feeding device of the selective laser melting equipment is arranged right above the selective laser melting table, so that the whole surface of the selective laser melting table can be covered through pipelines which are distributed in a lattice, the total volume of the selective laser melting table can be reduced, and the powder utilization ratio can be improved.

Description

technical field [0001] The invention relates to the field of laser selective melting equipment, in particular to a laser selective melting equipment. Background technique [0002] Because in the laser selective melting process, every time the powder spreading device spreads the powder, it needs to transport the metal powder once. Usually, the laser selective melting equipment performs the powder feeding action through the powder feeding cylinder. After feeding the powder from the powder feeding cylinder, during the powder spreading process of the powder spreading device, a lot of powder will enter the recovery tank before entering the forming area, resulting in a decrease in the utilization rate of the powder, and the scraper is in the process of scraping the powder in order to ensure the laying. The powder is on a horizontal plane, and the length of the powder needs to be extended. Each time the molding needs to prepare metal powder that is many times larger than the volum...
