Description

Technical Field

[0001] This invention relates to the field of centrifugal atomizing disc technology, and more particularly to a 3D printed metal powder centrifugal atomizing disc. Background Technology

[0002] The centrifugal atomizing disc is the core component for obtaining metal particles, and it has a crucial impact on the forming of metal particles and product quality. Metal particles are used in additive manufacturing, especially in the field of metal 3D printing, where the requirements for sphericity and particle size are extremely high. The metal particle preparation process is achieved by passing the metal mother liquor through this component.

[0003] In traditional centrifugal atomization operations, the centrifugal force cannot be kept stable, so the metal mother liquor cannot be fully dispersed into fine droplets during the atomization process. This directly results in the metal powder particles that are formed later being very uneven in size, and the fineness of the powder does not meet the ideal requirements. Summary of the Invention

[0004] This invention discloses a 3D printed metal powder centrifugal atomizing disk, which aims to solve the technical problems that may occur in traditional centrifugal atomization processes due to insufficient or unstable centrifugal force, resulting in incomplete atomization of the metal mother liquor, uneven particle size of the metal powder, and insufficient fineness.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In a preferred embodiment, the powder container is equipped with two atomizing powder spreading components inside, with a centrifugal atomizing disc located between the two components.

A servo motor is positioned above the sliding plate closest to the centrifugal atomizing disc, and the power output shafts of both servo motors are connected to rotating threaded rods via couplings. The bottom ends of the rotating threaded rods are rotatably connected to the bottom ends of the sliding plates closest to the centrifugal atomizing disc, while guide rods are fixedly connected to the bottom ends of the sliding plates furthest from the centrifugal atomizing disc. Sliding components are slidably connected to the outer side of the threaded rod. A movable plate is fixedly connected to the side of the two symmetrical sliding components away from the slide plate. Multiple sector gears are provided on the side of the movable plate away from the slide plate. A rotating shaft is fixedly connected to the side of the sector gears away from the slide plate.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] The 3D printing metal powder centrifugal atomizing disk disclosed in this invention is mainly used in scenarios where insufficient or unstable centrifugal force may lead to incomplete atomization of the metal mother liquor, uneven particle size of the metal powder, and insufficient fineness during traditional centrifugal atomization processes.

[0022] Reference Figures 1-8A 3D-printed metal powder centrifugal atomizing disc includes a metal powder centrifugal atomizer 1, a casing 2 fixedly connected to the top of the metal powder centrifugal atomizer 1, a metal solution tank 9 disposed inside the casing 2, a powder container 10 disposed below the metal solution tank 9, a centrifugal atomizing disc 13 disposed inside the powder container 10, a molybdenum mesh 14 fixedly connected to the top of the centrifugal atomizing disc 13, a drive motor 16 disposed below the powder container 10, and a rotating shaft 15 connected to the power output shaft of the drive motor 16 via a coupling, the top of the rotating shaft 15 being fixedly connected to a centrifugal atomizer 14. At the bottom end of the centrifugal atomizing disc 13, a circular hole is provided at the bottom end of the powder container 10. The rotating shaft 15 is rotatably connected to the inside of the circular hole. A centrifugal enhancement component 17 is provided on the outside of the centrifugal atomizing disc 13. The centrifugal enhancement component 17 includes multiple convex rollers 1709. The convex rollers 1709 are arranged in a ring around the outside of the centrifugal atomizing disc 13. All convex rollers 1709 are in contact with the outside of the centrifugal atomizing disc 13. Symmetrical arc-shaped fixing members 1701 are provided below each convex roller 1709. The opposite side of the arc-shaped fixing members 1701 is in contact with the outside of the rotating shaft 15.

[0023] Reference Figures 3-6 In a preferred embodiment, spring detection rods 1702 are fixedly connected to the opposite sides of the two arc-shaped fixing members 1701. A retaining plate 1704 is fixedly connected to the side of the spring detection rod 1702 away from the arc-shaped fixing member 1701. The bottom end of the retaining plate 1704 is fixedly connected to the inner bottom end of the powder container 10. A sliding plate 1703 is slidably connected to the bottom end of the arc-shaped fixing member 1701. The bottom end of the sliding plate 1703 is fixedly connected to the inner bottom end of the powder container 10. Two support frames 1705 are fixedly connected inside the bottom end of the powder container 10. The inner side of the support frame 1705... All are fixedly connected with annular parts 1706. Multiple annular connectors 1712 are fixedly connected to the outer side of the annular parts 1706. Vibration springs 1711 are fixedly connected to the side of the annular connectors 1712 closest to the centrifugal atomizing disc 13. Fixing plates 1710 are fixedly connected to the side of the vibration springs 1711 away from the annular connectors 1712. Movable frames 1707 are fixedly connected to the side of the fixing plates 1710 away from the vibration springs 1711. Fixing rods 1708 are fixedly connected to the inside of the movable frames 1707. The inner side of the convex rollers 1709 is movably connected to the outer side of the fixing rods 1708.

[0024] Specifically, the centrifugal atomizing disc 13 rotates at high speed. Multiple convex rollers 1709 are arranged in a ring around and in contact with the outer side of the centrifugal atomizing disc 13. The centrifugal atomizing disc 13 drives the convex rollers 1709 to rotate synchronously. The convex rollers 1709 move outside the fixed rod 1708 and roll within the movable frame 1707 as the centrifugal atomizing disc 13 rotates. The arc-shaped fixing members 1701 are symmetrically arranged, with their opposite sides in close contact with the outer side of the rotating shaft 15, thus fixing and limiting the rotation of the shaft 15. To ensure the rotating shaft 15 maintains a stable position and does not shift during normal high-speed rotation, the spring detection rod 1702 is in its natural state and is not subjected to additional tension or pressure. If the rotating shaft 15 shakes during high-speed rotation, it will compress the arc-shaped fixing member 1701 in contact with it. After being compressed, the arc-shaped fixing member 1701 will move in the opposite direction along the sliding plate 1703 (because the bottom end of the arc-shaped fixing member 1701 is slidably connected to the sliding plate 1703, and the sliding plate 1703 is the arc-shaped fixing member 1701). The movement of 701 provides a track. When the arc-shaped fixing part 1701 moves, it pulls the spring detection rod 1702 fixed to it, causing the spring detection rod 1702 to deform. The spring detection rod 1702 senses the displacement change of the rotating shaft 15 through its own deformation, thereby detecting that the rotating shaft 15 has shaken. This allows the staff to maintain and adjust the rotating shaft 15 and other components according to the detection results after the metal powder centrifugation is completed. During the rotation of the convex roller 1709 with the centrifugal atomizing disc 13 and the possible movement of the arc-shaped fixing part 1701, the annular connector 1712 is connected to the fixing plate 1710 through the vibration spring 1711. When the entire centrifugal enhancement component 17 vibrates due to the high-speed rotation of the centrifugal atomizing disc 13 or the shaking of the rotating shaft 15, the vibration spring 1711 will stretch and deform, playing a role in buffering and shock absorption, preventing the component from being damaged by excessive vibration. At the same time, it can make the movement of the convex roller 1709 and other components more stable, further ensuring the effect of centrifugal enhancement and the accuracy of the detection of the rotating shaft 15.

[0025] In practical applications, the convex roller 1709 contacts and rotates synchronously with the high-speed rotating centrifugal atomizing disc 13, which not only helps to support and reduce friction loss, but also enhances the centrifugal force effect, allowing the metal mother liquor to be more fully atomized under centrifugal action, resulting in more uniform and fine metal powder particles, thus improving atomization quality and efficiency.

[0026] It should be noted that the vibration spring 1711 undergoes expansion and contraction deformation when the component vibrates, which can effectively buffer the vibration caused by the rotation of the centrifugal atomizing disc 13 or the shaking of the shaft 15.

[0027] Reference Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8In a preferred embodiment, the powder container 10 is provided with two atomizing powder spreading components 11 inside, and a centrifugal atomizing disc 13 is located between the two atomizing powder spreading components 11. The atomizing powder spreading component 11 includes two symmetrical sliding plate components 1101. The opposite sides of the sliding plate components 1101 are fixedly connected to the inner wall of the powder container 10. A servo motor 1103 is arranged above the sliding plate component 1101 near the centrifugal atomizing disc 13. The power output shafts of the two servo motors 1103 are connected to rotating threaded rods 1104 through couplings. The bottom ends of the rotating threaded rods 1104 are rotatably connected to the bottom ends of the sliding plate components 1101 near the centrifugal atomizing disc 13. The bottom ends of the sliding plate components 1101 away from the centrifugal atomizing disc 13 are fixedly connected to guide rods 1105. The guide rods 1105 and the outer sides of the rotating threaded rods 1104 slide together. A sliding member 1113 is connected. A movable plate 1102 is fixedly connected to the side of the two symmetrical sliding members 1113 away from the slide plate 1101. Multiple sector gears 1109 are provided on the side of the movable plate 1102 away from the slide plate 1101. A rotating shaft 1107 is fixedly connected to the side of the sector gears 1109 away from the slide plate 1101. A belt 1108 is provided on the outer side of the rotating shaft 1107. A rotating motor 1106 is connected to the inner side of the rotating shaft 1107 near the centrifugal atomizing disc 13 through a coupling. A rotating gear 1110 is provided below the multiple sector gears 1109. The rotating gear 1110 and the sector gear 1109 are meshed through tooth grooves. A rotating rod 1111 is fixedly connected to the inner side of the symmetrical rotating gear 1110. A spreading plate 1112 is fixedly connected to the outer side of the rotating rod 1111.

[0028] Specifically, the servo motor 1103 is started, and its power output shaft drives the rotating threaded rod 1104 to rotate via a coupling. Since the sliding member 1113 is threadedly connected to the rotating threaded rod 1104, and also slidably connected to the guide rod 1105 (which guides the sliding member 1113 to prevent it from rotating with the rotating threaded rod 1104), the sliding member 1113 moves along the directions of the rotating threaded rod 1104 and the guide rod 1105 when the rotating threaded rod 1104 rotates. The sliding member 1113 is fixedly connected to the moving plate 1102, so the moving plate 1102 moves along with the sliding member 1113. The rotation of the servo motor 1103 can be controlled according to the height of the metal powder accumulation in the powder container 10, thereby adjusting the position of the moving plate 1102 and providing a suitable space for the subsequent oscillating and spreading operation of the spreading plate 1112. The rotating motor 1106 is then started to rotate... The power output shaft of motor 1106 drives the rotating shaft 1107 near the centrifugal atomizing disc 13 to rotate via a coupling. The rotating shaft 1107 is driven by belt 1108 to drive other rotating shafts 1107 to rotate synchronously. When the rotating shaft 1107 rotates, it drives the sector gear 1109 to rotate. Because the sector gear 1109 and the rotating gear 1110 mesh with each other through tooth grooves, when the sector gear 1109 rotates, it drives the rotating gear 1110 to rotate. The inner side of the rotating gear 1110 is fixedly connected to the rotating rod 1111. The rotation of the rotating gear 1110 will drive the rotating rod 1111 to rotate. When the rotating rod 1111 rotates, the evenly spreading plate 1112 fixed on the outer side of the rotating rod 1111 will swing back and forth. During the swinging process, the evenly spreading plate 1112 pushes and disperses the metal powder accumulated in the powder container 10, so that the metal powder can be evenly spread inside the powder container 10, ensuring that the powder distribution is flat and uniform.

[0029] In practical applications, the spreading plate 1112 swings back and forth, which can flatten and disperse the accumulated metal powder, making the metal powder more evenly distributed in the powder container 10, avoiding local accumulation that is too thick or too thin, and ensuring that the powder is in a consistent state when collecting and processing the metal powder in the future.

[0030] It should be noted that the servo motor 1103 drives the rotating threaded rod 1104 to rotate, thereby adjusting the position of the moving plate 1102, which can be adjusted in real time according to the height of the metal powder accumulation in the powder container 10.

[0031] Reference Figures 1-4In a preferred embodiment, a fixed frame 6 is fixedly connected to the inner side of the metal powder centrifugal atomizer 1. A vacuum pump 5 is provided at the top of the fixed frame 6. A vacuum pipe 4 is fixedly connected to the vacuum end of the vacuum pump 5. A hole is opened on the side of the metal powder centrifugal atomizer 1 near the fixed frame 6. The outer side of the vacuum pipe 4 is fixedly connected to the inside of the hole. The end of the vacuum pipe 4 away from the vacuum pump 5 is fixedly connected to the outer side of the machine body shell 2. The vacuum pipe 4 is connected to the inside of the vacuum shell. A connecting plate 7 is fixedly connected to the inside of the machine body shell 2. A support plate frame 8 is fixedly connected to the top of the connecting plate 7. The inner side of the support plate frame 8 is fixedly connected to the outer side of the metal solution tank 9. Two sealed observation windows 3 are fixedly connected to the front side of the machine body shell 2. A sealing plate 12 is fixedly connected to the bottom of the machine body shell 2. The top of the sealing plate 12 is fixedly connected to the bottom of the powder container 10. A perforation is opened on the sealing plate 12. The outer side of the rotating shaft 15 is movably connected to the inside of the perforation.

[0032] Working principle: Vacuum pump 5 continuously extracts air from the inside of the machine body shell 2 through vacuum pipe 4, creating a vacuum state inside, providing an oxygen-free environment for the subsequent atomization and cooling crystallization of metal mother liquor, and avoiding metal oxidation. The metal mother liquor in metal solution tank 9 flows into the casting cavity of centrifugal atomizing disc 13, ready for atomization operation.

[0033] The drive motor 16 starts, driving the rotating shaft 15 to rotate at high speed. Since the top of the rotating shaft 15 is fixedly connected to the bottom of the centrifugal atomizing disc 13, the centrifugal atomizing disc 13 rotates synchronously at high speed. The high-speed rotating centrifugal atomizing disc 13 generates a strong centrifugal force. Under the action of centrifugal force, the metal mother liquor in the cavity instantly diffuses to all sides and passes through the holes reserved in the molybdenum mesh 14. After passing through the holes, the metal mother liquor forms fine droplets. When these droplets fly in the vacuum environment, they cool and crystallize rapidly, initially forming metal powder particles. Multiple convex rollers 1709 are arranged in a ring around the outside of the centrifugal atomizing disc 13 and in contact with it. When the centrifugal atomizing disc 13 rotates at high speed, the convex rollers 1709 rotate with it on the one hand, and on the other hand, through The contact between itself and the centrifugal atomizing disc 13 provides auxiliary support and guidance for the rotation of the centrifugal atomizing disc 13, reducing energy loss during rotation and thus enhancing the centrifugal rotation effect, allowing the metal mother liquor to be atomized more fully and efficiently. The arc-shaped fixing part 1701 is symmetrically arranged and its inner side contacts the outer side of the rotating shaft 15, used to fix the position of the rotating shaft 15. If the rotating shaft 15 shakes during high-speed rotation, it will drive the arc-shaped fixing part 1701 in contact with it to move. When the arc-shaped fixing part 1701 moves, it will pull the spring detection rod 1702. The spring detection rod 1702 can sense this displacement change, thereby detecting whether the rotating shaft 15 has shaken, which is convenient for the staff to carry out maintenance according to the detection results.

[0034] The servo motor 1103 is started, and the power output shaft drives the rotating threaded rod 1104 to rotate via the coupling. Since the sliding member 1113 is threadedly connected to the rotating threaded rod 1104, and also slidably connected to the guide rod 1105 (which guides and prevents the sliding member 1113 from rotating), the sliding member 1113 moves along the direction of the rotating threaded rod 1104 and the guide rod 1105 when the rotating threaded rod 1104 rotates. Since the sliding member 1113 is fixedly connected to the moving plate 1102, the moving plate 1102 moves along with the sliding member 1113. The position of the moving plate 1102 can be adjusted according to the height of the metal powder accumulation in the powder container 10, providing a suitable operating range for the subsequent oscillating and evenly spreading of the evenly spreading plate 1112. The rotating motor 1106 is started, carrying... The rotating shaft 1107, located near the centrifugal atomizing disc 13, rotates. The rotating shaft 1107 is driven by the belt 1108, which drives other rotating shafts 1107 to rotate synchronously. When the rotating shaft 1107 rotates, it drives the sector gear 1109 to rotate. Since the sector gear 1109 and the rotating gear 1110 mesh through the tooth groove, the rotation of the sector gear 1109 will drive the rotating gear 1110 to rotate. The inner side of the rotating gear 1110 is fixedly connected to the rotating rod 1111. Therefore, the rotation of the rotating gear 1110 will drive the rotating rod 1111 to rotate, which in turn causes the evenly spreading plate 1112 fixed on the outer side of the rotating rod 1111 to swing back and forth. During the swinging process, the evenly spreading plate 1112 pushes and disperses the metal powder accumulated in the powder container 10, so that the metal powder is evenly spread inside the powder container 10.
