[0002] Nickel-based alloys are a class of alloys that have high strength and certain resistance to oxidation and corrosion at high temperatures of 650 to 1000℃.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Example 1: Refer to Figure 1-7As shown: A high-strength heat-resistant nickel-based alloy induction melting feeding device includes a feeding cylinder 3, a first feeding frame 6 fixedly connected to the top of the feeding cylinder 3, a second feeding frame 7 fixedly connected to the bottom of the feeding cylinder 3, an induction furnace 1 fixedly connected to the bottom of the second feeding frame 7, a feeding mechanism 2 installed on one side of the feeding cylinder 3, a support mechanism 5 installed on the other side of the feeding cylinder 3, an opening and closing mechanism 4 installed on the top of the first feeding frame 6, the feeding mechanism 2 includes a positioning plate 21, a second connecting shaft 216 rotatably connected to one side of the positioning plate 21, an active dial 29 fixedly connected to the outside of the second connecting shaft 216, a connecting column 211 fixedly connected to one side of the active dial 29, a cylindrical pin 210 fixedly connected to one end of the connecting column 211, a first connecting shaft 212 rotatably connected to one side of the positioning plate 21, and a support mechanism 5 fixedly connected to the outside of the first connecting shaft 212. A driven grooved wheel 22 is fixedly connected to the first connecting shaft 212. A locking arc 213 is formed on the outer surface of the driven grooved wheel 22, and a radial groove 214 is formed on the outer surface of the driven grooved wheel 22. One end of the first connecting shaft 212 passes through one side of the feeding cylinder 3 and is fixedly connected to the feeding box 23. The other side of the feeding box 23 is fixedly connected to the connecting pipe 215. One end of the connecting pipe 215 passes through the feeding cylinder 3 and is connected to the bearing 28. One side of the bearing 28 is fixedly connected to one side of the feeding cylinder 3, and one end of the bearing 28 is fixedly connected to the vacuum tube 24. A drive motor 27 is fixedly connected to one side of the positioning plate 21. One side of the drive motor 27 is fixedly connected to the top of the induction furnace 1. A first gear 25 is fixedly connected to the output end of the drive motor 27. A second gear 26 meshes with one side of the first gear 25. The middle part of the second gear 26 is fixedly connected to the outside of the second connecting shaft 216.

[0029] In this embodiment, the material is fed into the first feeding frame 6. At this time, the top opening of the feeding box 23 is connected to the bottom end of the first feeding frame 6. The material enters the feeding box 23 and, through the meshing of the first gear 25 and the second gear 26, the drive motor 27 can drive the first gear 25, the second gear 26, and the second connecting shaft 216 to rotate in sequence. When the second connecting shaft 216 rotates, it drives the active dial 29 to rotate. The connecting column 211 and the cylindrical pin 210 perform circumferential motion. 210 moves into the interior of the radial groove 214. At this time, the outer surface of the driving dial 29 rotates until it separates from the locking arc 213, driving the driven groove wheel 22 to rotate. After the driven groove wheel 22 rotates ninety degrees, the cylindrical pin 210 separates from the radial groove 214. At this time, the drive motor 27 stops working. Another radial groove 214 of the driven groove wheel 22 contacts the outer arc surface of the driving dial 29, locking the driven groove wheel 22. When the driven groove wheel 22 rotates ninety degrees, the first connecting shaft 212... As the feeding box 23 rotates, it rotates 90 degrees. At this time, the opening on the feeding box 23 rotates to a horizontal position and is not connected to the bottom of the first feeding frame 6. The vacuum pump connected to the vacuum tube 24 can evacuate the inside of the feeding box 23. Then, the drive motor 27 continues to work, driving the driven groove wheel 22 to rotate another 90 degrees. The opening on the feeding box 23 rotates to the bottom and connects to the top of the second feeding frame 7. The material inside the feeding box 23 enters the inside of the induction furnace 1 through the second feeding frame 7. The material in the vacuum environment can be added to the inside of the induction furnace 1 to prevent damage to the vacuum environment inside the induction furnace 1 during subsequent feeding and reduce the impact on the production quality of nickel-based alloys inside the induction furnace 1. During the rotation of the feeding box 23, the vacuum tube 24 and the connecting tube 215 are connected by the bearing 28. As the connecting tube 215 rotates with the feeding box 23, the vacuum tube 24 can remain unchanged to prevent the vacuum tube 24 from getting tangled together with the rotation of the feeding box 23 and affecting the vacuuming effect.

[0030] Example 2: Figure 1 , Figure 5 and Figure 6As shown, the opening and closing mechanism 4 includes a positioning base 44, the middle of which is fixedly connected to the outer surface of the first feeding frame 6. A positioning groove 45 is provided inside the positioning base 44, and an internal gear ring 49 is rotatably connected inside the positioning groove 45. A third gear 46 meshes with the inner ring surface of the internal gear ring 49, and a movable rack 47 meshes with one side of the third gear 46. An opening and closing plate 43 is fixedly connected to the top of the movable rack 47. A rotating shaft 48 is fixedly connected to the middle of the third gear 46, and one end of the rotating shaft 48 is rotatably connected to the top of the positioning base 44. A guide groove 410 is provided on the top of the positioning base 44, and the interior of the guide groove 410 is slidably connected to the exterior of the movable rack 47. A toggle rod 42 is fixedly connected to the outer surface of the internal gear ring 49, and a first electric push rod 41 is rotatably connected to one end of the toggle rod 42. One end of the first electric push rod 41 is fixedly connected to the outer surface of the feeding cylinder 3.

[0031] In this embodiment, when it is necessary to feed material into the feeding box 23, the first electric push rod 41 is used to push the connection between the push rod 42 and the actuating rod 42 to move. One end of the actuating rod 42 is fixed to the internal gear ring 49. When the first electric push rod 41 pushes the actuating rod 42 to move, the internal gear ring 49 rotates inside the positioning groove 45. The inner ring of the internal gear ring 49 is meshed with the third gear 46, and one side of the third gear 46 is meshed with the moving rack 47. The rotation of the internal gear ring 49 can drive the third gear 46 to rotate, and the rotation of the third gear 46 can drive the third gear 46 to rotate. The moving rack 47 moves and slides inside the guide groove 410, which can fix the movement path of the moving rack 47. The moving rack 47 moves outward, driving the opening and closing plate 43 connected to it to move outward, opening the middle of the opening and closing plate 43 to facilitate feeding material into the first feeding frame 6. After feeding is completed, the first electric push rod 41 drives the inner gear ring 49 to rotate in the opposite direction, causing the moving rack 47 and the opening and closing plate 43 to move towards the middle, closing the top of the first feeding frame 6 to prevent foreign objects from entering.

[0032] Example 3: According to Figure 1 and Figure 7 As shown, the support mechanism 5 includes clamping plates 52, two clamping plates 52 are installed on the outer surface of the vacuum tube 24, a connecting plate 51 is fixedly connected to the outside of the clamping plates 52, a rotating push rod 56 is rotatably connected to one side of the connecting plate 51, a guide rail 57 is slidably connected to one end of the connecting plate 51, and one side of the guide rail 57 is fixedly connected to the top of the induction furnace 1; a sliding rod 55 is rotatably connected to the other end of the rotating push rod 56, a second electric push rod 53 is fixedly connected to the outside of the sliding rod 55, and one side of the second electric push rod 53 is fixedly connected to the top of the induction furnace 1; a guide frame 54 is slidably connected to one end of the sliding rod 55, and one side of the guide frame 54 is fixedly connected to the top of the induction furnace 1.

[0033] In this embodiment, the second electric push rod 53 drives the sliding rod 55 to move. The sliding rod 55 slides inside the guide frame 54, which can fix the movement path of the sliding rod 55. Two rotating push rods 56 are rotatably connected to the outside of the sliding rod 55. The movement of the sliding rod 55 can push the rotating ends of the two rotating push rods 56 to move. The rotation angle of the two rotating push rods 56 changes, which pushes the two connecting plates 51 to move. The connecting plates 51 slide on the guide rail 57, which can fix the movement path of the connecting plates 51 and drive the distance between the two connecting plates 51 to change. Two clamping plates 52 are fixed to the outside of the vacuum tube 24. The vacuum tube 24 is a rigid pipe, which can provide support for the vacuum tube 24 and clamp and fix the vacuum tube 24 to prevent the vacuum tube 24 from being twisted together as the feeding box 23 rotates.

[0034] The operating method and working principle of this device are as follows: When it is necessary to feed material into the feeding box 23, the first electric push rod 41 is driven to move the connection between the push rod 42 and the first electric push rod 41. The internal gear ring 49 rotates inside the positioning groove 45, driving the third gear 46 to rotate. The moving rack 47 moves outward, driving the opening and closing plate 43 to move outward, opening the middle of the opening and closing plate 43. Material is fed into the first feeding frame 6. After feeding is completed, the first electric push rod 41 drives the internal gear ring 49 to rotate in the opposite direction, causing the moving rack 47 and the opening and closing plate 43 to move towards the middle, closing the top of the first feeding frame 6. At this time, the top opening of the feeding box 23 is connected to the bottom of the first feeding frame 6, and the material enters the inside of the feeding box 23. The drive motor 27 drives the second connecting shaft 216 to rotate, and the active dial 29 rotates accordingly. The connecting column 211 and the cylindrical pin 210 perform circumferential motion. The cylindrical pin 210 moves to the entry diameter. Inside the groove 214, the outer surface of the active dial 29 rotates until it separates from the locking arc 213, causing the driven groove wheel 22 to rotate. When the driven groove wheel 22 rotates ninety degrees, the first connecting shaft 212 rotates accordingly, causing the feeding box 23 to rotate ninety degrees. At this time, the opening on the feeding box 23 rotates to a horizontal position. The vacuum pump connected to the vacuum tube 24 can evacuate the inside of the feeding box 23. Then, the drive motor 27 continues to work, causing the driven groove wheel 22 to rotate another ninety degrees. The opening on the feeding box 23 rotates to the bottom and connects to the top of the second feeding frame 7. The material enters the inside of the induction furnace 1 through the second feeding frame 7. The second electric push rod 53 works to push the sliding rod 55 to move. The rotation angle of the two rotating push rods 56 changes, pushing the two connecting plates 51 to move, causing the distance between the two connecting plates 51 to change. The two clamping plates 52 cooperate to fix the outside of the vacuum tube 24, supporting the vacuum tube 24.
