Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy liquid technology, specifically to a medium-frequency induction furnace for aluminum alloy liquid. Background Technology

[0002] In the production process of aluminum alloys, molten aluminum alloy is often formed and cast. In industry, induction furnaces are usually used for aluminum alloy smelting, especially for aluminum-based master alloys or grain refiners.

[0003] According to the public announcement of an induction furnace for aluminum alloy melting (Announcement No.: CN219433774U), the above application shows that the aluminum alloy molten metal can be poured out by rotating the support block along the support frame using a hydraulic cylinder, without the need to lift and return the furnace. This avoids the dangers caused by lifting, moving, and tilting the furnace, and eliminates the problem of damage to the induction furnace due to shaking or operational errors when returning it to its original position. In addition, this type of induction furnace has a simple structure, is easy to produce, has low cost, and good performance.

[0004] However, in actual use, after long-term use of the induction furnace, if the induction furnace becomes loose when the hydraulic cylinder lifts it, there are no protective measures, making it difficult to maintain stability. This can easily cause the induction furnace to rotate rapidly under the influence of gravity, making it easy for the liquid inside to spill out and the induction furnace to be damaged. In view of this, we propose a medium-frequency induction furnace for aluminum alloy liquid. Utility Model Content

[0005] The purpose of this invention is to provide a medium-frequency induction furnace for aluminum alloy liquid to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a medium-frequency induction furnace for aluminum alloy liquid, comprising a base, a vertical plate fixedly connected to the outer wall of the base, a motor fixedly connected to the outer wall of the vertical plate, an output end of the motor penetrating the vertical plate and fixedly connected to a casing, a furnace body fixedly connected to the inner wall of the casing, a coil sleeved on the outer wall of the furnace body, a flow guide block fixedly connected to the upper outer wall of the furnace body, and a support assembly provided inside the base, the support assembly comprising:

[0007] An electric actuator is hinged to the lower outer wall of the housing. A fixing plate is fixedly connected to the fixed end of the electric actuator. An insert block is fixedly connected to the lower outer wall of the fixing plate. A moving block is slidably connected to the lower outer wall of the insert block.

[0008] A ratchet is rotatably connected to the outer wall of the moving block. A gear is fixedly connected to the outer wall of the ratchet, and a toothed plate meshes with the outer wall of the gear. A pawl is rotatably connected to the outer wall of the insert block.

[0009] Preferably, the insert block has a buffer assembly inside, the buffer assembly including a torsion spring, a rotating rod fixedly connected to the outer wall of the pawl, the rotating rod passing through the outer wall of the moving block and the torsion spring sleeved on the outer wall of the rotating rod, an insert rod fixedly connected to one end of the insert block near the moving block, the insert rod passing through the moving block and a spring fixedly connected to one end of the insert rod near the moving block, a sliding groove is formed on the outer wall of the fixing plate, a slider is slidably connected to the inner wall of the sliding groove, and a support block is fixedly connected to the outer wall of the slider away from the sliding groove. When the induction furnace is lifted, if the induction furnace is loose, the casing will rotate and press down on the electric push rod, and the electric push rod can support the casing.

[0010] Preferably, one end of the torsion spring is fixedly connected to the outer wall of the rotating rod. The other end of the torsion spring is fixedly connected to the inner wall of the insert block. The pawl and the ratchet are located on the vertical line of the same horizontal line. When the induction furnace shakes and the casing presses against the electric push rod, the insert rod is inserted into the moving block, causing the insert block to drive the pawl and the ratchet to engage, making it difficult for the ratchet to rotate towards the end closer to the guide block, thereby allowing the electric push rod to better support the casing.

[0011] Preferably, the outer wall of the movable block is rotatably connected to a rotating shaft, and the shaft of the ratchet and the shaft of the gear are both fixedly connected to the rotating shaft. The toothed plate is fixedly connected to the inner wall of the base. When the housing rotates to make the electric push rod drive the movable block to move, the gear moves on the toothed plate. Since the toothed plate and the gear mesh, the gear can rotate when the toothed plate moves. At this time, the ratchet can rotate with the gear. When the pawl and the ratchet are engaged, it is difficult for the pawl to rotate towards the end close to the guide block.

[0012] Preferably, the outer wall of the base is provided with a limiting groove, and the insert block and the moving block are slidably connected to the inner wall of the limiting groove. The length of the limiting groove is the same as the length of the lower outer wall of the casing, so that when the casing is driven to rotate by the motor, the electric push rod extends and retracts accordingly, so that the casing can drive the electric push rod to move when rotating, and both the insert block and the moving block slide on the inner wall of the limiting groove. At this time, the casing shakes, so that the casing will press the electric push rod, allowing the insert rod on the insert block to be inserted into the moving block. At this time, the pawl can lock the ratchet, so that the electric push rod can support the casing and limit the lower part of the casing.

[0013] Preferably, both ends of the lower outer wall of the fixing plate are provided with support components, and both ends of the outer wall of the fixing plate are provided with support blocks, so that the electric push rod can have a larger contact area with the base through the fixing plate, so that the electric push rod can better support the casing, and so that the furnace body can remain fixed when the casing drives the furnace body to rotate and loosens.

[0014] Preferably, the support block is configured as a right-angled triangle, with one right-angled side of the support block fitting against the outer wall of the base, and the other right-angled side of the support block being fixedly connected to the slider and slidably connected to the fixing plate, so that when the housing presses down on the electric actuator, the triangle of the support block can provide better support for the fixing plate.

[0015] Compared with the prior art, this utility model provides a medium-frequency induction furnace for aluminum alloy liquid, which has the following beneficial effects:

[0016] 1. This aluminum alloy molten metal is used in a medium-frequency induction furnace. When the casing is loose, it rotates and presses down on the electric push rod, causing the insert block to move down and drive the pawl to limit the ratchet. This makes it difficult for the ratchet to rotate towards the end close to the guide block. The ratchet is also fixedly connected to the gear, preventing the gear from moving towards the guide block. This allows the electric push rod to fix the position of the casing, so that the induction furnace will not rotate immediately when it is loosened, preventing damage to the induction furnace and spillage of the aluminum alloy molten metal.

[0017] 2. This aluminum alloy liquid medium frequency induction furnace uses a torsion spring to ensure that the pawl remains engaged with the ratchet as the insert block moves. The spring allows the insert block to reset, enabling the support assembly to be used repeatedly. The support block is always in contact with the base through the sliding groove and slider. Furthermore, the triangular shape of the support block improves the support effect of the fixed plate, allowing the casing to be better supported by the electric push rod.

[0023] like Figures 1-4As shown, this utility model provides a technical solution: a medium-frequency induction furnace for aluminum alloy liquid, including a base 1, an upright plate fixedly connected to the outer wall of the base 1, a motor 2 fixedly connected to the outer wall of the upright plate, the output end of the motor 2 passing through the upright plate and fixedly connected to a casing 3, a furnace body 4 fixedly connected to the inner wall of the casing 3, a coil 5 sleeved on the outer wall of the furnace body 4, a flow guide block 6 fixedly connected to the upper outer wall of the furnace body 4, and a support assembly 7 provided inside the base 1, the support assembly 7 including an electric push rod 71, a fixing plate 72, an insert block 73, a moving block 74, a ratchet 75, a gear 76, a toothed plate 77, and a pawl 78.

[0024] In one embodiment of this utility model, the electric actuator 71 is hinged to the lower outer wall of the housing 3, the fixed end of the electric actuator 71 is fixedly connected to the fixing plate 72, the lower outer wall of the fixing plate 72 is fixedly connected to the insert block 73, and the lower outer wall of the insert block 73 is slidably connected to the moving block 74.

[0025] In one embodiment of the present invention, a ratchet 75 is rotatably connected to the outer wall of a movable block 74, a gear 76 is fixedly connected to the outer wall of the ratchet 75, a toothed plate 77 is meshed with the outer wall of the gear 76, and a pawl 78 is rotatably connected to the outer wall of the insert block 73.

[0026] In addition, the insert block 73 is equipped with a buffer assembly 8, which includes a torsion spring 81. A rotating rod is fixedly connected to the outer wall of the pawl 78. The rotating rod passes through the outer wall of the moving block 74, and the torsion spring 81 is sleeved on the outer wall of the rotating rod. An insert rod 82 is fixedly connected to one end of the insert block 73 near the moving block 74. The insert rod 82 passes through the moving block 74, and a spring 83 is fixedly connected to one end of the insert rod 82 near the moving block 74. A groove 84 is provided on the outer wall of the fixing plate 72. A slider 85 is slidably connected to the inner wall of the groove 84. A support block 86 is fixedly connected to the outer wall of the slider 85 away from the groove 84. When the induction furnace is lifted, if the induction furnace is loose, the housing 3 will rotate and press down the electric push rod 71. The electric push rod 71 can support the housing 3, so that the induction furnace can remain stable.

[0027] In this embodiment of the invention, one end of the torsion spring 81 is fixedly connected to the outer wall of the rotating rod. The other end of the torsion spring 81 is fixedly connected to the inner wall of the insert block 73. The pawl 78 and the ratchet 75 are located on the vertical line of the same horizontal line. When the induction furnace shakes and the housing 3 presses against the electric push rod 71, the insert rod 82 is inserted into the moving block 74, causing the insert block 73 to drive the pawl 78 and the ratchet 75 to engage. This makes it difficult for the ratchet 75 to rotate towards the end closer to the guide block 6, thereby allowing the electric push rod 71 to better support the housing 3, ensuring that the induction furnace will not move when it is released, and preventing damage to the induction furnace.

[0028] In this embodiment of the invention, the outer wall of the movable block 74 is rotatably connected to a rotating shaft. The shaft of the ratchet 75 and the shaft of the gear 76 are both fixedly connected to the rotating shaft. The toothed plate 77 is fixedly connected to the inner wall of the base 1. When the housing 3 rotates, causing the electric push rod 71 to drive the movable block 74 to move, the gear 76 moves on the toothed plate 77. Since the toothed plate 77 meshes with the gear 76, the gear 76 can rotate when the toothed plate 77 moves. At this time, the ratchet 75 can rotate with the gear 76. When the pawl 78 engages with the ratchet 75, the pawl 78 is difficult to rotate towards the end close to the guide block 6, so that the electric push rod 71 can support the housing 3 and remain stable even when the induction furnace becomes loose.

[0029] In this embodiment of the utility model, a limiting groove is provided on the outer wall of the base 1. The insert block 73 and the moving block 74 are slidably connected to the inner wall of the limiting groove. The length of the limiting groove is the same as the length of the lower outer wall of the sleeve 3. When the sleeve 3 is driven to rotate by the motor 2, the electric push rod 71 extends and retracts accordingly. When the sleeve 3 rotates, it can drive the electric push rod 71 to move. The insert block 73 and the moving block 74 slide on the inner wall of the limiting groove. At this time, the sleeve 3 shakes, which presses the electric push rod 71 so that the insert rod 82 on the insert block 73 can be inserted into the moving block 74. At this time, the pawl 78 can lock the ratchet 75, so that the electric push rod 71 can support the sleeve 3 and limit the lower part of the sleeve 3. When the sleeve 3 becomes loose during feeding, its position can be kept fixed.

[0030] In the embodiments of this utility model, support components 7 are provided at both ends of the lower outer wall of the fixing plate 72, and support blocks 86 are provided at both ends of the outer wall of the fixing plate 72, so that the electric push rod 71 can have a larger contact area with the base 1 through the fixing plate 72, so that the electric push rod 71 can better support the shell 3, so that when the shell 3 drives the furnace body 4 to rotate and loosens, the furnace body 4 can be kept fixed, thereby preventing the aluminum alloy liquid from spilling out.

[0031] In this embodiment of the utility model, the support block 86 is set as a right triangle. One right-angled side of the support block 86 is attached to the outer wall of the base 1, and the other right-angled side of the support block 86 is fixedly connected to the slider 85 and slidably connected to the fixing plate 72. When the housing 3 presses down on the electric push rod 71, the triangle of the support block 86 can make the fixing plate 72 support the housing 3 better and the housing 3 can be better supported by the electric push rod 71.

[0032] In this invention, during use, raw materials are added to the furnace body 4 and heated by the coil 5 to melt them. When the motor 2 drives the casing 3 to rotate, causing the molten aluminum alloy to pour out, the casing 3 drives the electric push rod 71 to move on the base 1. At this time, the gear 76 moves and rotates on the toothed plate 77, and the electric push rod 71 extends and retracts accordingly, keeping the casing 3 hinged to the electric push rod 71. If the connection between the casing 3 and the base 1 becomes loose, the casing 3 will press against the electric push rod 71, causing the insert block 73 to drive the pawl 78 to limit the ratchet 75, making it difficult for the ratchet 75 to rotate towards the end near the guide block 6. Furthermore, the ratchet 75 and the gear 76 are fixed together. The fixed connection prevents the gear 76 from moving, thus allowing the electric push rod 71 to support the housing 3, fixing the position of the housing 3 and preventing the induction furnace from rotating immediately when it is released, thus preventing damage to the induction furnace and spillage of aluminum alloy. The torsion spring 81 ensures that the pawl 78 remains engaged with the ratchet 75 as it moves with the insert block 73. The spring 83 allows the insert block 73 to reset, enabling the support assembly 7 to be reused. The support block 86 is always in contact with the base 1 through the sliding groove 84 and the slider 85, and the triangular shape of the support block 86 can improve the support effect of the fixed plate 72, allowing the housing 3 to be better supported by the electric push rod 71.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
