Description

Technical Field

[0001] The utility model relates to the technical field of metal powder processing, in particular to a metal powder 3D printing device. Background Art

[0002] 3D printers are gradually appearing in people's vision, and metal powder laser sintering 3D printers, as an important means of industrial processing, are increasingly showing an important role that cannot be ignored. The powder spreading device is a very important part of the metal powder 3D printer, which directly affects the printing speed and printing quality of the workpiece. The powder spreading device of the existing metal powder 3D printer is mostly a roller powder spreading device. Such a powder spreading device requires the powder supply bin to be able to rise and fall, which will increase the complexity of the structure, and most roller powder spreading devices can only spread powder in one direction, which is less efficient.

[0003] A powder spreading device for a small metal powder 3D printer is proposed in a patent with publication number CN104308148B, which includes a slider A, a slider B, a slider C, a slider D, an outer baffle of a left powder return bin A, an inner baffle of a left powder return bin A, a molding bin bottom plate, a molding bin front baffle, a right powder return bin, an inner baffle of a right powder return bin B, a front baffle, a powder spreading funnel, and a left powder return bin. A slider A11 and a slider D14 are fixedly connected to the bottom surface of the bottom plate 31, and the slider A11 and the slider D14 are connected to the guide rails A21 and D24 through interference fit and can slide relative to each other on them, so that the entire left powder return bin 5, the right powder return bin 7 and the molding bin 6 can slide back and forth along the guide rails A21 and D24. The powder spreading funnel 4 is fixedly connected to the slider B12, and the slider B12 is connected to the guide rail B22 by interference fit and can slide relatively, that is, the powder spreading funnel 4 can slide left and right along the guide rail B22. The powder spreading funnel 4 is L-shaped, and the lower end is a funnel-shaped through hole. A scraper is provided at the bottom of the funnel. The metal powder material is added into the powder spreading funnel 4, and the powder spreading funnel 4 slides on the molding bin 6 and sprinkles the metal powder in the molding bin 6 for sintering. The thickness and area of ​​the sintered workpiece can be adjusted by the up and down lifting and the in and out movement of the molding bin 6. After sintering a layer, the powder spreading funnel 4 returns to scrape the remaining powder into the left return powder bin 5 and the right return powder bin 7 to recycle the powder to prevent waste. In this way, repeated sintering can finally print the required three-dimensional workpiece, but the following problems still exist in this patent:

[0004] The existing metal powder does not have a good leveling structure for spreading the powder during printing, so that the excess powder is easily wasted and the height is easily deviated after printing.

[0005] In view of the above problems, it is necessary to design a metal powder 3D printing device to overcome the above problems. Utility Model Content
