Description

Laser material-increasing oxidation preventing device Technical Field The utility model relates to the technical field of laser additive manufacturing, in particular to a laser additive anti-oxidation device. Background Additive manufacturing or 3D printing is a "bottom-up" material additive manufacturing method. In the traditional part manufacturing process, the material reduction manufacturing is often used, for example, wood is cut and polished into a required shape when a woodworker works, and the material reduction manufacturing belongs to the material reduction manufacturing. In contrast, additive manufacturing is a manufacturing method in which materials (including liquid, powder, wire, or block) are automatically added up to form a solid structure. Just as with a 3D printer, the material is "printed" layer by layer from bottom to top, which is an additive manufacturing. At present, additive manufacturing can be used in the manufacturing fields of aerospace, navigation, nuclear power, medical treatment, automobiles, molds, high-end tools and the like, however, oxidation phenomenon can occur to laser additive manufactured products after production, so that the quality of the products is reduced, and oxidation prevention treatment is needed, therefore, a laser additive oxidation prevention device is needed to be provided, and the problems are solved. Disclosure of utility model Aiming at the defects existing in the prior art, the embodiment of the utility model aims to provide a laser material-increasing anti-oxidation device so as to solve the problems in the background art. In order to achieve the above purpose, the present utility model provides the following technical solutions: A laser additive oxidation prevention device, comprising: the machine body is internally provided with a placing rack; The spraying unit is arranged in the machine body and used for spraying the laser additive manufactured products on the placing frame; the rotating unit is rotationally connected in the machine body and connected with the placing rack and is used for driving the placing rack to rotate; And one end of the reciprocating unit is arranged on the spraying unit, and the other end of the reciprocating unit is rotationally connected to the rotating unit and is used for driving the spraying unit to rotate in the machine body in a positive-negative alternate manner under the action of the rotating unit. Compared with the prior art, the laser additive manufacturing device has the advantages that the laser additive manufacturing device is arranged in a machine body and used for spraying laser additive manufacturing products on a placing rack, the rotating unit is rotatably connected in the machine body and connected with the placing rack and used for driving the placing rack to rotate, and the reciprocating unit is provided with one end arranged on the spraying unit and the other end rotatably connected on the rotating unit and used for driving the spraying unit to rotate in a positive-negative alternating mode in the machine body under the action of the rotating unit.
