Description

Technical Field

[0001] The present invention relates to the technical field of aluminum ingot processing, and specifically, to a vacuum high-temperature induction aluminum ingot melting furnace. Background Art

[0002] An aluminum ingot refers to raw material aluminum in daily industry. Among them, aluminum is a silver-white metal, ranking third in the earth's crust after oxygen and silicon. Aluminum has a relatively low density, only 34.61% of iron and 30.33% of copper. Therefore, it is also called a light metal. Due to its light weight, aluminum is often used to manufacture land, sea and air transportation vehicles such as cars, trains, subways, ships, airplanes, rockets and spaceships to reduce their own weight and increase the loading capacity. Among them, aluminum has good fluidity. In the processing of aluminum products, a vacuum high-temperature induction melting furnace can be used to heat the aluminum ingot to a liquid state and introduce the aluminum liquid into a mold for casting aluminum products. Due to the relatively high melting point of aluminum, when the vacuum high-temperature induction melting furnace is operating, there is a relatively high temperature nearby. And due to the lack of effective feeding measures in the traditional vacuum high-temperature induction melting furnace, the feeding of aluminum ingots requires manual participation by personnel, which is extremely likely to cause scalding of personnel. Based on this, we propose a vacuum high-temperature induction aluminum ingot melting furnace. Summary of the Invention

Detailed implementation mode

[0019] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present invention.

[0020] Embodiment 1 As Figures 1 to 8 shown, this embodiment proposes a vacuum high-temperature induction aluminum ingot melting furnace, including: A positioning base plate 1, one end of the positioning base plate 1 is fixedly connected with a positioning plate 2, and the top end of the positioning plate 2 is rotatably connected with a support shaft rod 3; A melting furnace main body 4, the melting furnace main body 4 is fixedly connected to one end of the support shaft rod 3, a feeding port 5 is opened at the top end of the melting furnace main body 4, and a plugging assembly 6 is arranged at the top end of the melting furnace main body 4 for closing the melting furnace main body 4; A driving motor 7, the driving motor 7 is fixedly connected to one side of the positioning plate 2, the output end of the driving motor 7 is fixedly connected with a driving spur gear 8, and one end of the support shaft rod 3 away from the melting furnace main body 4 is fixedly connected with a reduction spur gear 9, and the reduction spur gear 9 is meshed with the driving spur gear 8; A bearing seat 10, the bearing seat 10 is assembled on the top end of the positioning base plate 1 for providing aluminum ingots to the melting furnace main body 4; More specifically, the melting furnace main body 4 includes a power input system, a vacuum system and a furnace body; Among them, the vacuum system is composed of a mechanical pump, a Roots pump, etc. to maintain a vacuum environment in the furnace, Since the investment in the main body 4 of the melting furnace is relatively large, shortening the smelting cycle to improve the equipment utilization rate becomes an important factor in selecting the power of the power supply. In this embodiment, a power of 300 - 500 kW is selected for smelting each ton of aluminum ingots. The selection of the power supply frequency mainly considers that the molten pool can be fully stirred to facilitate the melting of aluminum ingots and the progress of the refining reaction. In order to obtain sufficient stirring, an auxiliary power supply for stirring is provided inside the furnace body; During the electromagnetic induction process, eddy currents will be generated in the main body 4 of the melting furnace to melt the aluminum ingots. This process can be used to refine high-purity aluminum liquid. Under vacuum smelting, it is easy to remove nitrogen, hydrogen, oxygen, and carbon dissolved in steel and alloys to a much lower level than under atmospheric pressure smelting. At the same time, for impurity elements with a vapor pressure higher than that of the matrix metal at the smelting temperature, they can be removed by volatilization, and the components of active elements such as aluminum, titanium, boron, and zirconium that need to be added to the aluminum ingots are easy to control. Therefore, the aluminum ingots smelted by vacuum induction melting can significantly improve various properties such as toughness, fatigue strength, corrosion resistance, high-temperature creep performance, and the magnetic permeability of magnetic alloys, which is a mature existing technology and will not be elaborated here; In this embodiment, a limiting groove 34 is opened in the middle of the positioning plate 2. The limiting groove 34 is an arc-shaped structure. One end of the main body 4 of the melting furnace close to the limiting groove 34 is fixedly connected with a guiding rod 35, and the guiding rod 35 is also movably connected inside the limiting groove 34. Through the setting of the limiting groove 34, it can cooperate with the guiding rod 35 to form an auxiliary support for the positioning bottom plate 1, greatly ensuring the stability of the positioning plate 2 during rotation. In other embodiments, alloy balls can be provided inside the limiting groove 34 or on the outer side of the guiding rod 35 to ensure the smoothness of the guiding rod 35 moving inside the limiting groove 34; In this embodiment, a lead-out pipe 36 is fixedly connected to the bottom end of the outer side of the main body 4 of the melting furnace, and a solenoid valve is provided on the lead-out pipe 36. Through the setting of the lead-out pipe 36, the molten aluminum liquid can be led out from the main body 4 of the melting furnace, and in combination with the setting of the solenoid valve, the on-off of the lead-out pipe 36 can be effectively controlled; The plugging assembly 6 includes a bearing seat 10. The bearing seat 10 is fixedly connected to the top end of the main body 4 of the melting furnace. A plugging shaft rod 11 is rotatably connected to the inner side of the bearing seat 10. A plugging door 12 is fixedly connected to the middle of the plugging shaft rod 11, and a driving spur gear 13 is fixedly connected to one end of the plugging shaft rod 11; In this embodiment, a sealing groove is opened in the middle of the bottom end of the plugging door 12, and a sealing gasket 37 is fixedly connected inside the sealing groove. Through the setting of the sealing gasket 37, after the plugging door 12 covers the feeding port 5, the sealing gasket 37 will be moved into the feeding port 5 to seal the feeding port 5, preventing the heat inside the main body 4 of the melting furnace from escaping from the connection gap between the plugging door 12 and the feeding port 5, and the sealing gasket 37 is made of high-temperature resistant material; The bearing seat 10 includes: The linear guide rod 14 is fixedly connected to one end of the top of the positioning base plate 1. A displacement slider 15 is vertically slidably connected to the outside of the linear guide rod 14. A transverse guide plate 16 is fixedly connected to one side of the displacement slider 15. A linear slider 17 is horizontally slidably connected to the outside of the transverse guide plate 16; In this embodiment, a limit piece 38 is fixedly connected to the top end of the linear guide rod 14, and a noise reduction pad is fixedly connected to the bottom end of the limit piece 38. Through the setting of the limit piece 38, the stroke of the displacement slider 15 can be guided to prevent the displacement slider 15 from detaching from the linear guide rod 14. At the same time, through the setting of the noise reduction pad, the collision noise between the displacement slider 15 and the linear guide rod 14 can be reduced, and the displacement slider 15 can be protected; The positioning column 18 is fixedly connected to one side of the linear slider 17. A linkage rack 19 is fixedly connected to the outside of the positioning column 18, and the linkage rack 19 is meshed and connected with the driving spur gear 13. A material loading assembly 20 is arranged at one end of the positioning column 18 away from the linear slider 17; The vertical plate 21 is fixedly connected to one end of the top of the positioning base plate 1 close to the positioning plate 2. A central shaft rod 22 is rotatably connected to the top end of the vertical plate 21. A speed reducer 23 is fixedly connected to the top of one side of the vertical plate 21. The power output end of the speed reducer 23 is fixedly connected to the central shaft rod 22. A driving motor 24 is fixedly connected to one side of the speed reducer 23. The output end of the driving motor 24 is fixedly connected to the power input end of the speed reducer 23; The eccentric plate 25 is fixedly connected to the middle of the central shaft rod 22. A linkage through groove 26 is formed in the middle of the eccentric plate 25, and the other side of the storage box 27 is also movably connected inside the linkage through groove 26; In this embodiment, a linkage column is fixedly connected to the other side of the linear slider 17. The linear slider 17 is movably connected inside the linkage through groove 26 through the linkage column. Through the setting of the linkage column, when the eccentric plate 25 rotates, the linkage column can be pressed to drive the linear slider 17 to perform adaptive displacement; In summary, under the connection between the speed reducer 23 and the central shaft rod 22, the speed reducer 23 can drive the eccentric plate 25 to rotate by means of the central shaft rod 22. And in cooperation with the connection between the linear slider 17 and the linkage through groove 26, the linear slider 17 can follow the rotation of the eccentric plate 25 and drive the displacement slider 15 to vertically displace under the limitation of the linear guide rod 14, so as to lift the material storage box 27 upward. When the displacement slider 15 reaches the top end of the linear guide rod 14, the displacement slider 15 can be blocked by the limit piece 38 to prevent the displacement slider 15 from detaching from the linear guide rod 14. And because the displacement slider 15 is blocked by the limit piece 38 and cannot continue to vertically displace, when the eccentric plate 25 continues to rotate, it will drive the linear slider 17 to linearly displace along the transverse guide plate 16, prompting the material storage box 27 to approach the feeding port 5. And when the linear slider 17 linearly displaces along the transverse guide plate 16, since the linear slider 17 is restricted inside the linkage through groove 26, the transverse guide plate 16 can be assisted and supported by means of the linear slider 17, preventing the displacement slider 15 from sliding down under the influence of gravity during linear displacement; Embodiment 2 As Figures 1 to 8 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes a loading component 20; In this embodiment, the loading component 20 includes: A material storage box 27, which is fixedly connected to one end of the positioning column 18. At the bottom of one side of the material storage box 27, two guiding shaft rods 28 are rotatably connected. At one end of the two guiding shaft rods 28 located inside the material storage box 27, a blocking plate 29 is fixedly connected; An eccentric linkage plate A30 and an eccentric linkage plate B31, which are respectively fixedly connected to one end of the two guiding shaft rods 28 away from the blocking plate 29. And a linkage bar 32 is rotatably connected between the two ends of the two guiding shaft rods 28 close to each other. At the bottom of the other side of the material storage box 27, a blocking motor 33 is fixedly connected, and the output end of the blocking motor 33 is fixedly connected to one of the guiding shaft rods 28; In this embodiment, a stability maintaining seat 39 is fixedly connected to the bottom of the other end of the material storage box 27, and the blocking motor 33 is bolted to one end of the stability maintaining seat 39. Through the setting of the stability maintaining seat 39, the blocking motor 33 can be effectively positioned, ensuring the stability of the transmission of the blocking motor 33 and facilitating subsequent maintenance.

[0021] A specific application of the above two embodiments is that the aluminum ingots are first poured into the interior of the storage box 27 and received by the blocking plate 29, and then the driving motor 24 is started to provide power for the reducer 23. Under the connection between the reducer 23 and the central shaft 22, the reducer 23 can drive the eccentric plate 25 to rotate with the help of the central shaft 22, and cooperate with the connection between the linear slider 17 and the linkage slot 26, so that the linear slider 17 can follow the rotation of the eccentric plate 25, drive the displacement slider 15 to vertically move under the limit of the linear guide rod 14, so as to lift the storage box 27 upward. When the displacement slider 15 reaches the top of the linear guide rod 14, the displacement slider 15 can be blocked by the limiting plate 38 to prevent the displacement slider 15 from detaching from the linear guide rod 14. Since the displacement slider 15 is blocked by the limiting plate 38 and cannot continue to move vertically, when the eccentric plate 25 continues to rotate, it will drive the linear slider 17 to move linearly along the transverse guide plate 16, so as to make the storage box 27 close to the feeding port 5; Before the storage box 27 reaches the feeding port 5, the linkage rack 19 will be pre-connected with the matching spur gear 13, and then the matching spur gear 13 can be toggled by the linkage rack 19, so that the blocking door 12 is turned over under the support of the blocking shaft 11, and the feeding port 5 is blocked. When the storage box 27 reaches the top of the feeding port 5, the blocking motor 33 is started to drive the guide shaft 28 connected thereto to rotate, and because the linkage bar 32 is connected between the eccentric linkage plate B31 and the eccentric linkage plate A30, when the guide shaft 28 connected to the eccentric linkage plate A30 rotates, the power of the blocking motor 33 can be transmitted to the other guide shaft 28 through the linkage bar 32, so that the two guide shafts 28 drive the two blocking plates 29 to rotate synchronously, and the rotation directions are opposite. When the two blocking plates 29 move away from each other, the aluminum ingot will fall into the melting furnace body 4 through the gap between the blocking plates 29, waiting for processing; The driving motor 24 is started in reverse to make the storage box 27 return to the initial position, and the blocking door 12 is covered on the feeding port 5 to seal the feeding port 5. The aluminum ingot is then melted through the melting furnace body 4. The molten liquid can be discharged through the outlet pipe 36, and the transmission motor 7 can be started to drive the transmission spur gear 8 to rotate. Under the connection between the transmission spur gear 8 and the reduction spur gear 9, the reduction spur gear 9 can drive the supporting shaft 3 to rotate adaptively. As the melting furnace body 4 is tilted, the liquid in the melting furnace body 4 can be concentrated and sent to the outlet pipe 36, so that the liquid can be discharged more thoroughly.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
