[0001] The present invention belongs to the field of additive manufacturing technology, and specifically relates to an additive manufacturing device and a manufacturing method for metal materials. Background Art

[0002] Additive manufacturing (AM) is a technique that uses a gradual accumulation of material to create solid parts. Compared to traditional material removal and cutting techniques, it is a "bottom-up" manufacturing approach. Over the past two decades, AM technology has experienced rapid development, with various terms such as "rapid prototyping," "3D printing," and "solid-body free-form fabrication" each conveying different aspects of the technology's characteristics.

[0003] The authorization publication number "CN115178754A" records: "This patent invention discloses an additive manufacturing method and an additive manufacturing device for metal materials, specifically relating to the field of additive manufacturing technology, including a base, a collection assembly is fixedly installed on the top of the base, a protective outer frame is fixedly installed on the top of the collection assembly, a driving assembly is provided in the protective outer frame, a powder spreading mechanism is provided in the middle of the driving assembly, a feeding pump is fixedly installed on one side of the collection assembly, an observation window is fixedly provided on the side of the protective outer frame away from the feeding pump, and a door frame is hingedly installed on the side of the protective outer frame away from the observation window. The present invention, by providing a powder spreading mechanism and using a driving assembly, can spread powder of different widths according to printing width requirements, reduce powder waste, and prevent powder from agglomerating and affecting subsequent powder spreading operations when spreading powder over a large horizontal area, and control the start or stop of the powder spreading mechanism's powder spreading operation."

[0004] The above patent uses a simple stirring mechanism to stir the metal material when transferring it to prevent the powder from agglomerating. However, when the metal material agglomerates due to humidity, it is impossible to dry the metal material, which easily causes the metal material to clump. At the same time, its stirring device cannot scrape off the powder on the inner wall of the storage tank, resulting in waste of metal material. When spreading the powder, the additive manufacturing process is carried out by controlling the metal powder to fall onto the printing table. It does not have a scraping device, which easily leads to uneven powder spreading. Summary of the Invention

The use method includes the following steps: Step 1, cleaning the printing platform 4: pushing the electric telescopic rod 708 to push the powder spreading mechanism 8 and the leveling cleaning mechanism 9 to move, so that the cleaning rod 904 is attached to the printing platform 4, turning on the adjustment motor 701, the adjustment motor 701 rotates to drive the adjustment synchronous wheel 702 to rotate, and the two fixed synchronous wheels 703 are rotated by the transmission of the synchronous belt, and the two fixed synchronous wheels 703 drive the threaded rod 705 to rotate, and the limit rod 706 is limited to make the moving block 707 drive the electric telescopic rod 708 and the connecting block 709 to move, thereby driving the cleaning rod 904 to move on the printing platform 4, and at the same time, the cleaning motor 902 drives the cleaning rod 904 to rotate to clean the surface of the printing platform 4;

[0055] Step 2: Evenly spread the metal material: Turn on the fixed motor 910, which drives the fixed gear 911 to rotate. Through the engagement of the fixed gear 911 and the installation gear 912, the connecting ring 907 drives the connecting plate 906 and the sealing plate 908 to move. At this time, the sealing plate 908 drives the laying plate 909 to move, and at the same time drives the cleaning rod 904 to move into the installation box 901. At the same time, the vacuum cleaner 905 removes dust from the cleaning rod 904. One end of the metal material is transmitted into the storage tank 801 through the external powder feeding device. Turn on the rotating motor 804, which drives the rotating gear 805 to rotate. Through the engagement of the rotating gear 805 and the transmission gear 806, The rotating rod 807 drives the rotating plate 810 to rotate, thereby driving the rotating tube 813 and the stirring plate 816 to move. By meshing the connecting gear 812 and the fixed gear ring 811, the rotating tube 813 and the stirring plate 816 move and rotate simultaneously. By adjusting the electric telescopic rod 808 to push the scraper 809 to move, the metal material can be prevented from agglomerating. The metal material passes to the bottom of the storage tank 801. The powder spreading mechanism 8 and the leveling and cleaning mechanism 9 are adjusted by the adjustment mechanism 7. The spreading plate 909 scrapes the metal material that falls from the storage tank 801 and evenly spreads the metal material on the printing platform 4. The printing platform 4 is driven to move by the fixed electric telescopic rod 3 to produce metal additives.

[0056] Step 3: Drying the metal material: The electric heating rod 815 and the heat conducting sheet 814 cooperate with each other, and the rotating tube 813 contacts the metal material, thereby drying the metal material.

[0057] Step 4: Collect metal materials: After printing is completed, turn on the transmission motor 601, and through the transmission of the transmission synchronization wheel 602, the transmission rod 603 drives the transmission plate 604 to rotate, and the excess metal materials are transmitted to the transmission slot 5 through the rotation of the transmission plate 604 and collected by the collection bucket 10.
