Abstract

The invention discloses a method and device for recycling residual powder on a metal material increase manufacturing substrate. The device comprises a sealing bin, a pneumatic vibrator arranged outside the sealing bin, and a vibration clamping part arranged on the inner side wall of the sealing bin and used for transmitting vibration. The vibration clamping part is connected with the pneumatic vibrator and used for clamping a substrate of a forming part and providing mechanical vibration for the substrate. The sealing bin is provided with a high-pressure gas gun and an inert gas inlet. By means of the method and device, residual powder on the substrate can be thoroughly removed, the powder where impurities are removed can be recycled, and materials are saved; and due to the fact that the whole recycling process is performed under the protection of inert gas, the powder is prevented from being oxidized and affected with damp, and it is guaranteed that the original quality of the powder does not change.

Description

technical field [0001] The invention relates to the field of additive manufacturing of powder materials, in particular to a method and device for recovering residual powder on metal additive manufacturing substrates. Background technique [0002] Additive manufacturing, also commonly known as 3D printing, is a technology that uses CAD design data to accumulate material layer by layer to manufacture solid parts. Compared with traditional material removal (cutting) technology, it is a "bottom-up" material accumulation process. Manufacturing method. Compared with traditional manufacturing technologies, additive manufacturing has the advantages of being able to form parts with complex shapes, high forming precision, and saving materials. [0003] The molding materials of additive manufacturing can be divided into three categories: powder materials, linear materials and liquid materials according to the different forms. Among them, powder molding materials include metal powder, ...
