Description

Technical Field

[0001] This application relates to the field of aluminum alloy ingot melting furnace technology, and in particular to a melting furnace for aluminum alloy ingots with quantitative feeding capability. Background Technology

[0002] In the production and processing of aluminum alloy materials, the melting of aluminum alloy ingots is a crucial step. Currently, various types of aluminum alloy melting furnaces exist on the market. Their working principle mainly involves heating the aluminum alloy ingots above their melting point using heat sources such as high-temperature burners or resistance heaters, melting them into a liquid state. However, existing aluminum alloy melting furnaces generally suffer from a significant problem in the ingot addition stage: the inability to precisely meter the ingots. In actual production, overfeeding can cause molten aluminum alloy to overflow from the furnace, wasting raw materials and potentially leading to safety accidents; underfeeding will interrupt the melting process, affecting production efficiency and increasing production costs. For example, in some aluminum alloy foundries, workers manually add aluminum alloy ingots based on experience. Due to the lack of precise feeding control methods, inaccurate feeding frequently occurs, leading to frequent production abnormalities and difficulty in guaranteeing product quality. Moreover, manually adding aluminum alloy ingots is labor-intensive, requires high operator skills, and increases labor costs accordingly. Therefore, developing a melting furnace for aluminum alloy ingots capable of precise metering is of significant practical importance. Utility Model Content

Therefore, they should not be construed as limitations on the present utility model.

[0025] Reference Figures 1-7One embodiment is shown: the melting furnace 1 has an overall cavity structure, and its top is firmly connected to an opening structure for feeding aluminum alloy ingots by welding. The opening structure is precisely sized to fit the aluminum alloy ingots, and the weld joint is strictly sealed to prevent heat loss. In this embodiment, the bottom of the melting furnace 1 has sufficient thickness and strength and is tightly fixed to the ground foundation by anchor bolts. The anchor bolts are evenly distributed around the bottom of the melting furnace 1, and each bolt is equipped with a corresponding nut and washer to enhance the stability of the connection and ensure that the melting furnace 1 can stably bear the liquid weight of the molten aluminum alloy ingots and withstand the high-temperature environment. The furnace wall is composed of a multi-layer structure. The inner layer is made of high-temperature resistant corundum refractory bricks, which are tightly bonded by a masonry process, with the gaps between each refractory brick controlled within a very small range to ensure high-temperature resistance. The outer layer is made of ceramic fiber material with good heat insulation properties, which is covered on the outside of the inner refractory material by an adhesive process. The ceramic fiber material is bonded tightly and evenly, effectively reducing heat loss and preventing burns to operators. Mounting bracket 2 has a frame-like structure. Its bottom is precisely fixed to the top of melting furnace 1 by multiple high-strength bolts. The bolts pass through pre-drilled mounting holes at the bottom of mounting bracket 2 and corresponding screw holes at the top of melting furnace 1. Each bolt is tightened to the specified torque to ensure a firm connection between mounting bracket 2 and melting furnace 1. Mounting plates for mounting drive mechanism 3 are fixed to the frame of mounting bracket 2 by welding. The welded joints between the mounting plate and the frame are ground to ensure connection strength and flatness. The top is tightly fitted with mounting slots by bolts to achieve a stable installation. The rotating shaft 8 of drive mechanism 3 is horizontally set on both sides of melting furnace 1. Its two ends are rotatably connected to mounting bracket 2 by bearing seats. The bearing seats are firmly fixed to mounting bracket 2 by bolts to ensure smooth rotation of shaft 8. Transmission box 9 is firmly mounted on mounting bracket 2 by welding. The internal space is closed, and worm gear 10, worm wheel 11, first bevel gear 12, and second bevel gear 13 are all installed inside transmission box 9. The worm gear 11 meshes with the worm 10, ensuring high meshing precision and smooth transmission. The first bevel gear 12 is coaxially fixed to the bottom of the worm gear 11 via a key connection, ensuring synchronous rotation. The worm gear 11 is rotatably connected inside the transmission box 9. The second bevel gear 13 meshes with the first bevel gear 12 and is coaxially fixed to the rotating shaft 8 via a key connection, ensuring effective power transmission. The handwheel 14 is fixed to one end of the worm 10 via a key connection for easy operation. The connecting housing 5 of the feeding mechanism 4 has a placement groove 15 for placing aluminum alloy ingots welded to its top. The weld between the placement groove 15 and the connecting housing 5 is well sealed to prevent foreign objects from entering. The connecting housing 5 is securely installed on the mounting frame 2 near the top opening of the melting furnace 1 via welding or bolt connection. The dropping groove 22 at its bottom is precisely aligned vertically with the top opening of the melting furnace 1, ensuring that the aluminum alloy ingots can fall smoothly into the melting furnace 1.The connecting cavity 7 within the connecting housing 5 provides space for the pusher frame 6 to move. The two sides of the pusher frame 6 are slidably connected to the sliding grooves on the inner wall of the connecting cavity 7 via sliders. The high precision of the sliders and grooves allows the pusher frame 6 to move smoothly back and forth. One end of the pusher frame 6 is hinged to the component that drives its movement via a pin, ensuring flexible movement.

[0026] The implementation principle of the above embodiment is as follows: When melting aluminum alloy ingots, the aluminum alloy ingots are placed into the furnace through the top opening of the melting furnace 1. The heating device inside the furnace, such as a resistance heating wire or a gas burner, is activated to raise the temperature inside the furnace to the melting point of the aluminum alloy ingots, thus completing the melting operation. The mounting frame 2 provides stable support for the entire equipment, ensuring that the positions of each component are fixed and resisting the thermal expansion and contraction, vibration, and other external forces generated during the operation of the melting furnace 1. When it is necessary to drive the melting furnace 1 to swing, the operator rotates the handwheel 14. Rotating the handwheel 14 drives the worm gear 10 to rotate, the worm gear 10 drives the worm wheel 11 to rotate, the worm wheel 11 drives the first bevel gear 12 to rotate, the first bevel gear 12 drives the second bevel gear 13 to rotate, and the second bevel gear 13 drives the rotating shaft 8 to rotate, thereby realizing the swing of the melting furnace 1. The swing speed and amplitude can be adjusted according to production needs by using gears with different gear ratios. During quantitative feeding, aluminum alloy ingots are arranged sequentially in the placement slot 15 at the top of the connecting shell 5. The drive component works, such as the drive motor 16 driving the relevant transmission components to move the connecting rod 21 hinged to the push slot frame 6, which in turn moves the push slot frame 6 within the connecting cavity 7. The end of the push slot frame 6 pushes the aluminum alloy ingot at the bottom of the placement slot 15 into the melting furnace 1 through the dropping slot 22. After completing one push, it returns to the initial position, and the quantitative feeding is achieved in a cycle.

[0027] Reference Figure 1 , Figure 2 , Figure 4One embodiment is shown as follows: A rotating shaft 8 horizontally passes through both sides of the melting furnace 1, with its two ends mounted in bearing seats via high-precision bearings. The bearing seats are tightly fixed to the corresponding positions on the mounting frame 2 by bolts, ensuring the stability and concentricity of the rotating shaft 8 during rotation. A transmission box 9 is securely mounted on the mounting frame 2 by welding. Its body is made of high-strength material, and its internal space is precisely designed to accommodate the worm 10, worm wheel 11, first bevel gear 12, and second bevel gear 13. The worm 10 is mounted in a specific position within the transmission box 9 via bearings at both ends, ensuring flexible rotation and maintaining good meshing with the worm wheel 11, which rotates inside the transmission box 9. The meshing precision between the worm wheel 11 and the worm 10 is rigorously adjusted to ensure the accuracy and stability of power transmission. The first bevel gear 12 is tightly connected to the shaft at the bottom of the worm wheel 11 via a flat key. The high precision of the fit between the flat key and the keyway ensures that the first bevel gear 12 rotates synchronously when the worm wheel 11 rotates. The second bevel gear 13 meshes with the first bevel gear 12 and is coaxially fixed to the rotating shaft 8 via a flat key, ensuring that the second bevel gear 13 can effectively drive the rotating shaft 8 to rotate under the drive of the first bevel gear 12. The rotating handwheel 14 is fixed to one end of the worm gear 10 via a key connection. The surface of the rotating handwheel 14 is designed with anti-slip texture to facilitate the operator to apply force to rotate it.

[0028] The implementation principle of the above embodiment is as follows: When the operator rotates the handwheel 14, the handwheel 14 drives the worm gear 10 to rotate within the transmission box 9. Due to the meshing relationship between the worm wheel 11 and the worm gear 10, the rotation of the worm gear 10 drives the worm wheel 11 to rotate. The rotation of the worm wheel 11 drives the first bevel gear 12, which is fixed coaxially, to rotate. The first bevel gear 12, through meshing, drives the second bevel gear 13 to rotate. Because the second bevel gear 13 is fixed coaxially with the rotating shaft 8, the rotation of the second bevel gear 13 ultimately causes the rotating shaft 8 to rotate. The melting furnace 1 and the rotating shaft 8 are connected by rotation, thereby realizing the oscillation of the melting furnace 1 around the rotating shaft 8. This multi-stage gear transmission structure can amplify the small force applied by the operator to the handwheel 14 through the transmission ratio between the gears and effectively transmit it to the melting furnace 1, achieving precise control of the oscillation of the melting furnace 1. Furthermore, according to different production process requirements, the speed and amplitude of the oscillation of the melting furnace 1 can be flexibly adjusted by changing gears with different gear ratios to meet the diverse needs in the aluminum alloy ingot melting process.

[0029] Reference Figure 6 , Figure 7One embodiment is shown as follows: A placement groove 15 is welded to the top of the connecting housing 5. The size and shape of the placement groove 15 are precisely adapted to the placement of the aluminum alloy ingots, and the welded joints are ground and rust-proofed. The aluminum alloy ingots are arranged tightly in the vertical direction within the placement groove 15, with a very small gap reserved between adjacent ingots to ensure both tight arrangement and prevent jamming. The drive motor 16 is fixed to the side of the connecting housing 5 via a motor mounting bracket, which is connected to the connecting housing 5 with bolts, ensuring a secure connection and accurate motor mounting position. The output shaft of the drive motor 16 is connected to the third bevel gear 17 via a key to ensure effective power transmission. The rotating shaft 18 is mounted in pre-drilled mounting holes on both sides of the connecting housing 5 via bearings. The bearings, rotating shaft 18, and mounting holes have high precision fit, ensuring smooth rotation of the rotating shaft 18. The fourth bevel gear 19 is fixed to the rotating shaft 18 via a key and precisely meshes with the third bevel gear 17. The meshing gap has been rigorously adjusted. Fixed rods 20 are welded to both sides of the rotating shaft 18. The welds between the fixed rods 20 and the rotating shaft 18 are strong, ensuring that they will not loosen during rotation. The end of the fixed rod 20 is hinged to the connecting rod 21 via a pin. The pin fits tightly with the connecting holes of the fixed rod 20 and the connecting rod 21, allowing for flexible rotation. The other end of the connecting rod 21 is hinged to the push slot frame 6 via a pin, similarly ensuring flexible connection.

[0030] The implementation principle of the above embodiment is as follows: When the drive motor 16 is started, the output shaft of the drive motor 16 drives the third bevel gear 17 to rotate. Due to the meshing relationship between the third bevel gear 17 and the fourth bevel gear 19, the fourth bevel gear 19 drives the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 causes the fixed rods 20 on both sides to rotate synchronously, and the rotation of the fixed rods 20 drives the connecting rod 21 hinged at the end to move. The movement of the connecting rod 21 then drives the pusher frame 6 hinged to it to move in the communicating cavity 7 within the communicating housing 5. During the movement, the end of the pusher frame 6 pushes the aluminum alloy ingot located at the bottom of the placement slot 15, causing it to fall into the melting furnace 1 through the dropping slot 22 at the bottom of the communicating housing 5. When the drive motor 16 reverses, the pusher frame 6 returns to the initial position under the drive of the connecting rod 21, ready to push the next aluminum alloy ingot. By controlling the forward and reverse rotation and the running time of the drive motor 16, the movement frequency and amplitude of the pusher frame 6 can be precisely controlled, thereby achieving precise control of the quantitative feeding of aluminum alloy ingots and meeting the different production needs of the melting furnace 1.

[0031] Reference Figure 1 , Figure 6One embodiment is shown: a material discharge groove 22 is cut into the bottom of the connecting shell 5. The material discharge groove 22 is rectangular in shape, with dimensions precisely adapted to the passage of aluminum alloy ingots. The edges of the material discharge groove 22 are polished to prevent the aluminum alloy ingots from being scratched when falling. When the aluminum alloy ingots are arranged in the placement groove 15, the bottom aluminum alloy ingot can fall naturally into the pusher frame 6 under the action of gravity. The shape and size of the pusher frame 6 are adapted to the connecting cavity 7, and its internal space can accommodate a single aluminum alloy ingot, facilitating the smooth movement of the aluminum alloy ingot towards the material discharge groove 22 when pushed. The sliding track of the pusher frame 6 in the connecting cavity 7 adopts a high-precision chute and slider structure. The chute is opened on the inner wall of the connecting cavity 7, and the slider is installed on both sides of the pusher frame 6. The high precision of the two ensures that the pusher frame 6 moves smoothly.

[0032] The implementation principle of the above embodiment is as follows: After the aluminum alloy ingots are arranged vertically in the placement slot 15, the bottom aluminum alloy ingot will fall into the pusher slot 6 due to gravity. When the drive mechanism 3 moves the pusher slot 6 within the connecting cavity 7, the pusher slot 6 will push the aluminum alloy ingots falling into it towards the discharge slot 22. Because the bottom surface of the pusher slot 6 has an inclined angle and the movement is smooth, the aluminum alloy ingots smoothly pass through the discharge slot 22 under the action of the pusher slot 6 and fall into the melting furnace 1 below. After the pusher slot 6 completes one pushing action, it returns to the initial position under the control of the drive mechanism 3. At this time, the next aluminum alloy ingot in the placement slot 15 will fall into the pusher slot 6, and the above process is repeated to achieve continuous quantitative feeding of aluminum alloy ingots. Through this design, the number of aluminum alloy ingots falling into the melting furnace 1 each time can be accurately controlled, ensuring that the melting process of aluminum alloy ingots in the melting furnace 1 is stable and efficient, and avoiding adverse effects on the melting process due to excessive or insufficient feeding.

[0033] The working principle of this device is as follows: When the melting furnace 1 is working, the aluminum alloy ingot is first placed in the placement groove 15 of the feeding mechanism 4 connected to the housing 5. The drive motor 16 starts, and through the third and fourth bevel gears, the rotating shaft 18 rotates, driving the fixed rod 20 and the connecting rod 21 to move, which in turn moves the pusher frame 6 within the connecting cavity 7. The aluminum alloy ingot at the bottom of the placement groove 15 falls into the pusher frame 6, is pushed to the feeding groove 22, and falls into the melting furnace 1. At the same time, rotating the handwheel 14, through the worm gear 10, worm wheel 11, and bevel gears, causes the rotating shaft 8 to drive the melting furnace 1 to swing, promoting the melting of the aluminum alloy ingot. By controlling the operation of the drive motor 16, the feeding amount can be precisely controlled, achieving quantitative feeding and efficient melting.

[0034] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
