Description

Technical Field

[0001] The present invention relates to the technical field of metal powder manufacturing, and in particular to a metal powder manufacturing device for improving the quality of intelligent manufacturing powder. Background Art

[0002] The use of intelligent manufacturing has improved the intelligence and innovation of the value chain of industries such as metal additive manufacturing, mechanical parts, mechanical 3D printing and mold material manufacturing, and further improved the deep integration of informatization and industrialization. The metal powder used in metal additive, mechanical parts, and 3D printing mold materials needs to have the characteristics of uniformity, high smoothness, small particle size difference, and high temperature resistance. Generally, metal powders need to further optimize the Mn / C ratio and other element ratios on the basis of Fe-Mn-Al-Si high energy absorption alloys, add trace elements such as V, Ti, and Nb, and combine with solid solution aging to produce dispersion strengthening while inhibiting grain growth. Low oxygen production conditions need to be maintained during production. Gas atomization is a method of manufacturing fine metal powders by using the principle of rapid solidification by spraying inert gas (N2, Ar, He) in raw materials. It can produce high-quality powders with few oxidation and impurity problems. In addition, the use of inert gas during the spraying process makes it easy to control the surface quality of the manufactured powder. It can be used to manufacture metal powders used in metal additive, mechanical parts, 3D printing and other fields.

[0003] However, in the inert gas injection method, the metal droplets are decomposed by high-pressure gas, and the liquid powder falls to the bottom and undergoes a cooling and solidification process. The metal droplets are easily affected by the gas decomposition intensity, resulting in uneven droplet decomposition. At the same time, the fine powder produced by gas decomposition is greatly affected by the gas pressure. The fine powder adheres to the surface of the metal powder, resulting in reduced surface smoothness and low sphericity of the metal powder, which reduces the yield of high-quality metal powder.

[0004] The patent application publication number CN113145854A discloses a vacuum electrode induction melting double-flow gas atomization metal powder device, including a melting chamber and an atomization chamber, the melting chamber is located above the atomization chamber, and the melting chamber is connected to the atomization chamber, the melting chamber includes an induction coil, an atomization nozzle and a vertically arranged metal rod, the atomization chamber includes a shell, the shell top wall is arranged as a double-layer cavity structure, the upper end of the shell top wall is provided with a high-pressure air inlet, the lower surface of the top wall is provided with a plurality of gas outlets, the gas outlets are extended from the center of the top wall to the edge so as to be arranged in a long strip shape, and the plurality of gas outlets are evenly distributed along the central axis of the shell in an annular shape; the lower end of the atomization chamber is provided with a collection tank and a gas recovery device, and the collection tank and the gas recovery device are both connected to the shell. The device can be used to prepare fine spherical metal powders, and a sheath gas flow flowing from top to bottom is formed in the atomization chamber. Under the action of the sheath gas flow, the mutual collision and bonding between the atomized droplets are reduced, thereby reducing the formation of satellite powder. However, the following problems exist at the same time: 1. The sheath airflow is concentrated on the top of the collecting chamber, and the gas pressure difference in the collecting chamber is large, so the fine dust will diffuse greatly. The diffused fine dust will adhere to the coarse dust, resulting in satellite powder.

[0005] 2. The uniformity of metal dust particle size cannot be guaranteed. Summary of the invention

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] like Figure 1-7 As shown, the present invention discloses a metal powder manufacturing device for improving the quality of smart manufacturing powder, including a smelting component 10 for melting an alloy rod 100 to form a molten metal, an atomizing component 20 for gas atomizing the molten metal to form a metal powder, and a collection chamber 30 for collecting the atomized metal powder.

[0032] like Figure 3 As shown, the alloy rod 100 is straightened by the straightening device 60, and the bottom of the alloy rod 100 is conical. During smelting, it extends into the conical induction coil 11. The induction coil 11 is powered on through the power cord 12. A smelting shield 13 is provided on the outside of the induction coil 11. The molten droplets formed by the melting of the alloy rod 100 are atomized and cooled by the inert gas through the atomization component 20 to obtain spherical metal powder. Coil smelting does not require a crucible, and the smelting process is simple to control. The molten droplets after smelting are atomized by an inert gas, which is suitable for the preparation of active metals such as alloys containing elements such as V, Ti, Nb, or alloy powders with high purity requirements.

[0033] During the atomization manufacturing process of metal powder, fine powder and coarse powder will be generated. Coarse powder is the main source of finished metal powder, and fine powder will affect the molding quality of metal powder. Figure 6 It is used to explain the movement process of fine powder and coarse powder in the process of manufacturing powder by traditional metal powder manufacturing equipment. When the metal droplets are atomized by inert gas, the metal droplets are impacted and broken by the high-speed airflow, and the pressure distribution difference appears in the internal space of the collection chamber 30. Specifically, Figure 6 As shown, a high-pressure zone is formed directly below the high-speed airflow of the atomization component 20 that breaks up the molten droplets, and a low-pressure zone is formed outside the high-pressure zone. The coarse powder falls along the airflow due to the influence of gravity, but the fine powder is less affected by gravity and is significantly affected by the difference in pressure distribution. It will first be dispersed to the low-pressure zone and then fall along the airflow. After the fine powder is dispersed outward, the dispersion surface is significantly increased, and the falling fine powder gathers on the outer surface of the coarse powder to form satellite powder, which affects the molding quality of the coarse powder. In order to remove the satellite powder that affects the quality of the coarse powder, it is necessary to control the fine powder not to move to the low-pressure zone, but to directly pass through the high-pressure zone and fall. In this way, the coarse powder and the fine powder will be relatively distinguished, reducing the appearance of satellite powder.

[0034] The present invention eliminates the pressure distribution difference of the gas in the collection chamber 30 by installing a booster assembly 40 in the collection chamber 30. The fine powder and coarse powder generated after the metal droplets are broken by the high-pressure gas flow will fall along their respective broken areas. After the pressure distribution difference is eliminated, the original movement path of the coarse powder is not affected, but the fine powder will no longer diffuse outward due to the pressure difference, but will fall along the route after the broken area, and the satellite powder generated is significantly reduced, so that metal powder with high sphericity and fluidity can be manufactured, the fine powder adhering to the surface of the coarse powder is reduced, the smoothness of the metal powder surface is improved, and the powder quality and high-quality powder output are improved.

[0035] Furthermore, a boosting assembly 40 for eliminating the pressure distribution difference of the gas in the collection chamber 30 is provided by setting a boosting chamber 41 outside the collection chamber 30. The boosting chamber 41 is a closed chamber. The boosting chamber 41 is connected to the high-pressure inert gas through a boosting intake pipe 42. The boosting chamber 41 introduces the high-pressure inert gas into the collection chamber 30 through multiple boosting pipes 43, thereby eliminating the pressure distribution difference of the gas inside the collection chamber 30.

[0036] like Figure 3 As shown, the outlet end 432 of the boost pipe is concentrated in the high-pressure area where the molten droplets are atomized by the inert gas, the difference in pressure distribution of the fine powder during the process of changing from liquid to solid is reduced, the coarse powder and the fine powder are distinguished, and the generation of satellite powder is reduced.

[0037] Furthermore, the boost pipe inlet end 431 is evenly spaced and layered on the inner wall of the boost chamber 41, so that the high-pressure inert gas can enter the boost pipe 43 with a balanced pressure. The boost pipe outlet end 432 is evenly spaced and layered inside the collecting chamber 30. After passing through the boost pipe 43, the high-pressure inert gas is evenly pressure-distributed on the periphery of the high-pressure zone, which is beneficial to reducing the pressure distribution difference, further distinguishing the coarse powder and the fine powder, and reducing the generation of satellite powder.

[0038] Furthermore, an end cover 433 is hinged at the end of the boost pipe outlet end 432, and the end cover 433 is opened by the push of the high-pressure gas. When the boost pipe 43 stops boosting, the end cover 433 falls freely due to gravity, preventing metal powder from entering the boost pipe 43 and affecting the use of the boost pipe 43. The opening and closing degree of the end cover 433 should not be too large, which will affect the free fall of the end cover 433 by gravity, and it is easy to control within 150°.

[0039] Furthermore, the particle uniformity of the coarse powder produced by the molten droplets being atomized by inert gas and the output of the fine powder are easily affected by the stability of the airflow at the outlet of the atomizing component 20. When the airflow is not uniform in the outlet cross section, it is easy to cause large differences in the diameters of the coarse powder particles after atomization, increase the amount of fine powder produced, and reduce the molding quality of the metal powder. Especially for high-flow and high-pressure gas atomization, the uneven distribution of the airflow outlet is more obvious. Installing a gas pressure equalizing component 50 in the atomizing component 20 to balance the injection pressure of the atomizing gas at the airflow outlet can improve the stability of the airflow at the outlet of the atomizing component 20, reduce the difference in the distribution of the diameters of the coarse powder particles after atomization, reduce the amount of fine powder produced, and improve the size balance of the metal powder.

[0040] Furthermore, the gas pressure equalizing assembly 50 is arranged in the protective shell 21, and the gas pressure equalizing assembly 50 introduces high-pressure inert gas through the pressure equalizing inlet pipe 52, and the high-pressure inert gas enters the pressure equalizing chamber 53 through the pressure equalizing ring pipe 51, and the pressure equalizing ring pipe 51 is connected to the pressure equalizing chamber 53 through a plurality of connecting pipes 511, and the pressure equalizing ring pipe 51 can perform preliminary pressure equalization distribution on the input high-pressure inert gas, and the pressure equalizing chamber 53 is a closed cavity, and the whole is in the shape of a torus, and the top surface 531 of the pressure equalizing chamber 53 is connected to the upper edge of the melt slide 534 through the ring sheet 535, and the bottom surface 531 of the pressure equalizing chamber 53 is connected to the upper edge of the melt slide 534 through the ring sheet 535, and the bottom surface 531 of the pressure equalizing chamber 53 is connected to the upper edge of the melt slide 534 through the ring sheet 535. The lower edge of the melt slide 534 is connected through the second ring piece 536. The second ring piece 536 is in the shape of a fan-shaped slope. The pressure equalizing chamber 53 further outputs the high-pressure inert gas to the through hole 5361 of the fan-shaped slope of the second ring piece 536 through a plurality of gas equalizing pipes 537. The oblique setting of the fan-shaped slope of the second ring piece 536 gathers the outflowing high-pressure inert gas. Through the secondary balance of the pressure equalizing ring pipe 51 and the gas equalizing pipe 537, the stability of the outlet airflow of the fan-shaped slope of the second ring piece 536 can be improved, which is conducive to reducing the difference in the distribution of the diameter of the coarse powder particles after atomization and reducing the amount of fine powder generated.

[0041] Furthermore, a plurality of air-equalizing pipe air inlet ends 5371 are evenly distributed on the inner wall 533 of the pressure-equalizing chamber at layered intervals, and a plurality of air-equalizing pipe air outlet ends 5372 are evenly distributed on the ring sheet 2 536 at layered intervals, such as Figure 5 As shown, by arranging the gas equalizing pipes 537 in layers with uniform intervals, it is beneficial to further improve the pressure balance of the high-pressure inert gas, and can further improve the stability of the airflow at the outlet of the fan-shaped inclined surface of the ring plate 2 536.

[0042] Furthermore, the pressure equalizing chamber 53, the gas equalizing pipe 537, the ring piece 1 535, the ring piece 2 536 and the melt slide 534 are integrally formed. The mold can be conveniently used to produce the gas pressure equalizing assembly 50, the gas pressure equalizing assembly 50 has a higher overall strength, and the atomization stability is stronger during use. At the same time, the service life of the gas pressure equalizing assembly 50 can be increased, and the stability of the uniform distribution of the outlet airflow can be improved.

[0043] Furthermore, in the present invention, a gas recycling system is added to supply the inert gas in the collection chamber 30 to the boost chamber 41 to reduce production costs. Specifically, a gas recovery device 70 is connected to the collection chamber 30. The inert gas in the collection chamber 30 is collected, cooled and filtered by the gas recovery device 70 and then supplied to the boost chamber 41. The gas recovery device 70 has many applications in reality and will not be introduced in detail here.

[0044] like Figure 7 As shown in the figure, for metal powders formed under different production conditions, the SEM electron scanning microscope was used to inspect the forming of metal powders with an average particle size of 100μm:

[0045] Figure 7 A is a photo of the unpressurized assembly 40, in which the metal powder has poor smoothness, many satellite powders, and large differences in particle size;

[0046] Figure 7 B is a photo of the pressurized assembly 40, where the smoothness of the metal powder is significantly improved, the satellite powder is reduced, but the particle size difference is large;

[0047] Figure 7 C is a photograph after the pressurization component 40 and the gas pressure equalization component 50 are installed. The metal powder has better smoothness, less satellite powder, and smaller particle size difference.

[0048] It can be concluded that adding the boost component 40 and the gas pressure equalizing component 50 can improve the smoothness of the metal powder, reduce the attachment of satellite powder, reduce the difference in metal powder particle size, and improve the molding quality of the metal powder.

[0049] Principle of the invention: The present invention discloses a metal powder manufacturing device for improving the quality of intelligent manufacturing powder. Through the booster component 40, high-pressure inert gas is introduced into the collection chamber 30 to reduce the difference in gas pressure distribution in the collection chamber 30, thereby reducing the adhesion of fine powder to coarse powder, improving the smoothness of metal powder molding and the output of high-quality powder, and through the gas pressure equalization component 50, the injection pressure of the atomizing gas at the airflow outlet is balanced, the stability of the airflow at the outlet of the atomizing component 20 is improved, the difference in metal powder particle diameter is increased, and the molding quality of the metal powder is improved.
