Description

Technical Field

[0001] This invention belongs to the field of aluminum alloy production technology, and more specifically, relates to an aerospace aluminum alloy manufacturing production line. Background Technology

[0002] Aluminum alloy is a lightweight metal material made by adding a certain amount of other alloying elements to aluminum. These alloying elements usually include copper, silicon, magnesium, etc., and sometimes non-metallic elements such as carbon and sulfur. Aluminum alloy has low density, high strength, good plasticity, and excellent mechanical, physical and corrosion resistance properties. It is widely used in building decoration, aerospace, aviation, transportation, electromechanical, light chemical and daily necessities and other fields.

[0003] Patent application CN210616138U discloses a novel aluminum alloy production line, including a conveyor line. A grinding device is installed on the side of the conveyor line, and a power switch is provided on one side of the grinding device. A conveyor belt is installed on the surface of the conveyor line, and symmetrical drive rollers are provided on the inner side of the conveyor belt. The conveyor belt is driven by the drive rollers. An electric motor is installed on one side of the conveyor line. A partition is provided on the side of the conveyor line. Four equidistant infrared sensors and a buzzer are installed on the side of the partition. A microcontroller is also installed inside the partition.

[0004] Although the aforementioned novel aluminum alloy production line transports aluminum alloy via a conveyor line, manual demolding of the aluminum alloy is required during the demolding process, which is time-consuming and labor-intensive, greatly reducing work efficiency. At the same time, workers are too close to the high-temperature furnace, which can easily cause danger. In addition, some production lines use automatic demolding, but during the demolding process, it is easy for material feeding and demolding to occur simultaneously, causing metal material to flow out along with the demolding, resulting in resource waste.

[0005] In summary, the present invention provides an aerospace aluminum alloy manufacturing production line to solve the above-mentioned problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide an aerospace aluminum alloy manufacturing production line. Its advantages include: a melting assembly located at the center of the upper side of the first support platform can melt solid pure aluminum, converting it into a liquid aluminum alloy, thereby effectively removing impurities and improving the purity of the aluminum alloy. A stop block can remove the fixation on the lower end of the melting assembly, allowing the liquid aluminum alloy to be better fed into multiple molds, where it cools and solidifies to form the desired shape. Furthermore, a rotating shaft located on the inner side of the recess allows ropes wound around its circumference to pull the blocking assembly upwards, thus removing the seal on the multiple molds. Simultaneously, a pusher assembly pushes the cooled and solidified aluminum alloy from the molds for demolding, effectively avoiding the inconvenience of manual demolding, reducing labor costs, and significantly improving work efficiency. It also effectively prevents the simultaneous operation of feeding and demolding from causing metal material to flow out with the demolding process, reducing resource waste.

[0007] To achieve the above objectives, the present invention provides the following technical solution: An aerospace aluminum alloy manufacturing production line includes: a first support platform, a melting component mounted on the middle of the upper side of the first support platform, a stop block slidably fitted on the front side of the lower end of the melting component, a second support platform mounted on the lower side of one end of the first support platform, a plurality of molds mounted on the upper side of the front end of the second support platform, a transmission pipe connected to the periphery of the plurality of molds mounted on the lower end of the melting component, and a push block assembly and a blocking assembly slidably fitted on both ends of the molds respectively; A recessed block is fixed in the middle of the front side of the first support platform. A rotating shaft is rotatably fitted to the inner side of the recessed block. A rope is wound around the circumference of the rotating shaft. The upper and lower ends of the rope are fixed to the stop block and the blocking component, respectively. A conveyor belt is rotatably fitted to the front end of the second support platform. A grinding component is installed on the upper side of the front end of the conveyor belt. A feeding component is installed on one side of the grinding component.

[0008] By adopting the above technical solution, the melting component located in the middle of the upper side of the first support platform can melt solid pure aluminum and convert it into liquid aluminum alloy, thereby effectively removing impurities and improving the purity of the aluminum alloy. The stop block can remove the fixation on the lower end of the melting component, allowing the liquid aluminum alloy to be better fed into multiple molds, where it cools and solidifies to form the desired shape. Furthermore, a rotating shaft located on the inner side of the recess allows ropes wrapped around its circumference to pull the blocking component upwards, thus removing the seal on the multiple molds. Simultaneously, the pusher component pushes the cooled and solidified aluminum alloy out of the molds, effectively avoiding the hassle of manual demolding, reducing labor costs, and greatly improving work efficiency. It also effectively prevents the simultaneous operation of feeding and demolding from causing metal material to flow out with the demolding process, reducing resource waste.

[0009] The present invention is further configured such that: the smelting assembly includes an annular frame installed at the middle of the upper side of the first support platform, a hopper installed at the middle of the upper end of the annular frame, a furnace installed between the upper side of the first support platform and the lower end of the hopper, a fuel tank installed at the upper rear end of the first support platform, and a plurality of combustion tubes fixed to one side of the fuel tank.

[0010] By adopting the above technical solution, the fuel tank set on the upper rear end of the first support platform can provide power to multiple combustion tubes, thereby allowing multiple combustion tubes to smelt solid pure aluminum in the furnace by spraying fire, converting it into liquid aluminum alloy, thereby removing non-metallic inclusions, homogenizing the aluminum alloy composition, and effectively improving the quality of the aluminum alloy.

[0011] The present invention is further configured such that: a plurality of combustion tubes are located inside the furnace, the lower end of the furnace is provided with a discharge port, the baffle is slidably fitted inside the discharge port, and the lower end of the discharge port is connected to the upper end of the transmission pipe.

[0012] By adopting the above technical solution, the stop block is slidably engaged in the discharge port, allowing the stop block to open or close the discharge port. Thus, the position of the stop block can be adjusted according to whether material needs to be discharged, preparing for the next step of injecting liquid aluminum alloy into multiple molds.

[0013] The present invention is further configured such that: the push block assembly includes an opening on the upper side of the rear end of the second support platform, a first motor fixed to one side of the second support platform, a rotating rod rotatably engaged in the opening, a plurality of gears fixed to the periphery of the rotating rod, a slider slidably engaged in one end of the mold, and a toothed plate fixed to the middle of one side of the slider, wherein the toothed plate meshes with the gears, and the output end of the first motor is fixed to one end of the rotating rod.

[0014] By adopting the above technical solution, the first motor drives the rotating rod to rotate, which in turn drives multiple gears to rotate synchronously. As a result, the multiple gears mesh and rotate with multiple toothed plates, which in turn drive the slider to slide and engage with the inner side of multiple molds. The slider then pushes the cooled and solidified aluminum alloy inside the mold to demold, achieving automatic demolding and further reducing the labor required by the workers.

[0015] The present invention is further configured such that: the blocking component includes two rectangular blocks fixed to the upper side of the front end of the second support platform, a connecting block slidably engaged with the inner side of the two rectangular blocks, and springs are fixed between the inner side of the lower end of the two rectangular blocks and the opposite sides of the connecting block; the connecting block corresponds to the other end of the plurality of molds; and the lower end of the rope is fixed to the middle of the connecting block.

[0016] By adopting the above technical solution, the lower end of the rope is fixed to the middle of the connecting block, so that the rope is wound around the circumference of the rotating shaft to pull the connecting block. Thus, the position of the connecting block can be adjusted according to whether demolding is required. Furthermore, the springs installed on the inner sides of the lower ends of the two rectangular blocks and between the opposite sides of the connecting block cause the springs to elastically return the connecting block to one end of the multiple molds. This effectively prevents the connecting block from failing to close tightly at one end of the multiple molds by relying solely on the rope, thereby improving the sealing performance of the molds.

[0017] The present invention is further configured such that: a second motor is fixed on one side of the concave block, the output end of the second motor is fixed to one end of the rotating shaft, and a slot is opened on the upper side of the front end of the first support platform, an electric guide rail is installed on the inner side of the slot, and the output end of the electric guide rail is fixed to one side of the stop block.

[0018] By adopting the above technical solution, the electric guide rail drives the stop block to move left and right on the upper side of the first support platform, thereby opening or closing the discharge port and better discharging the liquid aluminum alloy. The second motor drives the rotating shaft to rotate, so that the rope is wrapped around the circumference of the rotating shaft, thereby driving the connecting block to slide inside the two rectangular blocks. This eliminates the sealing of multiple molds, so that multiple molds are in a sealed state when discharging and in an open state when discharging is closed, thereby achieving better demolding and reducing the waste of metal materials.

[0019] The present invention is further configured such that: the grinding assembly includes a support block installed on the upper side of the front end of the conveyor belt, two cylinders respectively fixed on opposite sides of the support block, two clamping blocks respectively fixed to the output ends of the two cylinders, a third motor fixed to the middle of the upper side of the support block, and a grinding disc fixed to the output end of the third motor, the grinding disc being located above the conveyor belt.

[0020] By adopting the above technical solution, two cylinders drive two clamping blocks to move closer together, thereby clamping the cooled and solidified aluminum alloy. This prevents the aluminum alloy from shaking during grinding, which could lead to substandard results. This effectively improves the stability of the aluminum alloy during clamping. At the same time, a third motor drives the grinding disc to rotate, thereby grinding the clamped aluminum alloy and removing oxide scale, rust, and other corrosive substances from the surface. This makes the surface of the aluminum alloy smoother and flatter, ensuring the surface quality and overall aesthetics of the aluminum alloy, while also improving its corrosion resistance.

[0021] The present invention is further configured such that: the feeding assembly includes a feeding port opened at the front end of the support block, a guide plate fixed at the lower front side of the feeding port, and a receiving box located directly below the guide plate, and the feeding port corresponds to the front end of the conveyor belt.

[0022] By adopting the above technical solution, the guide plate set at the lower front side of the discharge port can be used to guide the polished aluminum alloy into the receiving box for collection and storage, reducing the amount of manual work in the later stage and thus improving work efficiency.

[0023] The present invention is further configured such that: a condenser is fixed on the lower side of the front end of the second support platform, and air pipes are fixed on both sides of the condenser, with one end of the air pipes corresponding to a plurality of the molds.

[0024] By adopting the above technical solution, one end of the air pipe corresponds to multiple molds, which rapidly cools the liquid aluminum alloy injected into the mold, accelerates the cooling and solidification of the liquid aluminum alloy, and at the same time, the rapid cooling causes the liquid aluminum alloy to shrink, so that it can be separated from the mold, which facilitates the subsequent demolding of the formed aluminum alloy.

[0025] The present invention is further configured such that: a sealing gasket is fixed on the inner side of the connecting block and the slider, and the sealing gasket corresponds to both ends of the mold.

[0026] By adopting the above technical solution, and by using sealing gaskets that correspond to both ends of the mold, the liquid aluminum alloy can be prevented from leaking out from both ends of the mold, thus further enhancing the mold's sealing performance.

[0027] In summary, the beneficial technical effects of the present invention are as follows: A melting assembly located at the center of the upper side of the first support platform can melt solid pure aluminum, converting it into a liquid aluminum alloy. This effectively removes impurities and improves the purity of the aluminum alloy. Furthermore, a stop block can remove the fixation on the lower end of the melting assembly, allowing the liquid aluminum alloy to be better fed into multiple molds, where it cools and solidifies to form the desired shape. By using a rotating shaft located on the inner side of the recessed block, a rope wrapped around the circumference of the rotating shaft pulls the blocking component upward, thereby removing the seal of the blocking component on multiple molds. At the same time, the pushing block component pushes the cooled and solidified aluminum alloy in multiple molds to demold, effectively avoiding the trouble of manual demolding, reducing the labor force of workers, and greatly improving work efficiency. It also effectively prevents the situation where metal material flows out with the demolding due to the simultaneous operation of material feeding and demolding, reducing resource waste.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1-6The present invention discloses an aviation aluminum alloy manufacturing production line, comprising: a first support platform 1, a melting component 2 installed in the middle of the upper side of the first support platform 1, a stop block 3 slidably fitted on the front side of the lower end of the melting component 2, a second support platform 4 installed on the lower side of one end of the first support platform 1, a plurality of molds 5 installed on the upper side of the front end of the second support platform 4, a transmission pipe 6 connected to the periphery of the plurality of molds 5 installed at the lower end of the melting component 2, and a push block component 7 and a blocking component 8 slidably fitted at both ends of the molds 5 respectively; A recessed block 9 is fixed in the middle of the front side of the first support platform 1. A rotating shaft 10 is rotatably fitted to the inner side of the recessed block 9. A rope 11 is wound around the circumference of the rotating shaft 10. The upper and lower ends of the rope 11 are fixed to the stop block 3 and the blocking component 8, respectively. A conveyor belt 12 is rotatably fitted to the front end of the second support platform 4. A grinding component is installed on the upper side of the front end of the conveyor belt 12. A feeding component is installed on one side of the grinding component.

[0033] The working principle of this device is as follows: When aluminum alloy production is required, solid pure aluminum is first added to the melting assembly 2 and the melting assembly 2 is started. At this time, the melting assembly 2 melts the solid pure aluminum and transforms it into liquid aluminum alloy. Then, the stop block 3 and the blocking assembly 8 are moved. At this time, the transmission pipe 6 is opened, and the blocking assembly 8 seals the outlet end of the mold 5. Then, the liquid aluminum alloy is introduced into multiple molds 5 through the transmission pipe 6. After cooling and solidification, it forms an aluminum alloy of a specified shape. After cooling and solidification, the rotating shaft 10 is rotated, causing the rotating shaft 10 to drive the rope 11 to rotate and wind around the circumference of the rotating shaft 10 for winding. Thus, the upper end of the rope 11 is aligned with the stop block 3. Block 3 is loosened, causing the stop block 3 to close the transmission pipe 6. Simultaneously, the lower end of the rope 11 pulls the blocking component 8 upward, canceling the seal on multiple molds 5. Then, the push block component 7 is activated, pushing the cooled and solidified aluminum alloy out into the interior of multiple molds 5 and pushing it above one end of the conveyor belt 12. Then, the conveyor belt 12 and the grinding component are activated. The conveyor belt 12 carries the cooled and solidified aluminum alloy for conveying. When it is conveyed to the bottom of the grinding component, the grinding component grinds the cooled and solidified aluminum alloy. After grinding, the conveyor belt 12 continues to convey it to the unloading component for collection and storage, thus completing the production of aluminum alloy.

[0034] It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.

[0035] Reference Figure 3 The smelting assembly 2 in this embodiment includes an annular frame 13 installed in the middle of the upper side of the first support platform 1, a hopper 14 installed in the middle of the upper end of the annular frame 13, a furnace 15 installed between the upper side of the first support platform 1 and the lower end of the hopper 14, a fuel tank 16 installed on the upper side of the rear end of the first support platform 1, and a plurality of combustion tubes 17 fixed to one side of the fuel tank 16; see reference Figure 5In this embodiment, multiple combustion tubes 17 are located inside the furnace 15. The lower end of the furnace 15 is provided with a discharge port 18. The baffle 3 is slidably fitted inside the discharge port 18. The lower end of the discharge port 18 is connected to the upper end of the transmission pipe 6.

[0036] When smelting solid pure aluminum, the solid pure aluminum is first put into the hopper 14. At this time, the solid pure aluminum falls down along the inner wall of the hopper 14 according to its own gravity and falls into the furnace 15. Then, the fuel tank 16 can provide power to multiple combustion tubes 17, so that the multiple combustion tubes 17 ignite and smelt the solid pure aluminum in the furnace 15, converting it into liquid aluminum alloy. After the conversion is completed, the baffle 3 is moved. At this time, the liquid aluminum alloy is introduced into the transmission pipe 6 through the discharge port 18 and injected into multiple molds 5.

[0037] Reference Figure 5 The pusher assembly 7 in this embodiment includes an opening on the upper rear end of the second support platform 4, a first motor 19 fixed to one side of the second support platform 4, a rotating rod 20 rotatably engaged within the opening, multiple gears 21 fixed to the periphery of the rotating rod 20, a slider 22 slidably engaged with one end of the mold 5, and a toothed plate 23 fixed to the middle of one side of the slider 22. The toothed plate 23 meshes with the gears 21, and the output end of the first motor 19 is fixed to one end of the rotating rod 20. (Refer to...) Figure 2 In this embodiment, the blocking assembly 8 includes two rectangular blocks 24 fixed to the upper front end of the second support platform 4, and a connecting block 25 slidably fitted inside the two rectangular blocks 24. Springs are fixed between the lower inner sides of the two rectangular blocks 24 and the opposite sides of the connecting block 25. The connecting block 25 corresponds to the other end of the plurality of molds 5, and the lower end of the rope 11 is fixed to the middle of the connecting block 25. (Refer to...) Figure 5 In this embodiment, a second motor 26 is fixed on one side of the recess 9. The output end of the second motor 26 is fixed to one end of the rotating shaft 10. A slot is opened on the upper side of the front end of the first support platform 1. An electric guide rail is installed inside the slot. The output end of the electric guide rail is fixed to one side of the stop block 3.

[0038] When demolding the cooled and solidified aluminum alloy, the second motor 26 is started. The output end of the second motor 26 drives the rotating shaft 10 to rotate, causing the rope 11 to rotate and wind around the circumference of the rotating shaft 10. As a result, the upper end of the rope 11 loosens the stop block 3. At the same time, the electric guide rail is started, which drives the stop block 3 to close the transmission pipe 6. The lower end of the rope 11 pulls the connecting block 25 upward. At this time, the two ends of the connecting block 25 slide against the inner sides of the two rectangular blocks 24, and the spring is elastically stretched. At this time, the connecting block 25 releases the seal on the multiple molds 5, so that the discharge port 18 is in the position during demolding. When closed, multiple molds 5 are in the open state; conversely, when feeding, the discharge port 18 is in the open state, and multiple molds 5 are in the sealed state. Then, the first motor 19 is started, and the output end of the first motor 19 drives the rotating rod 20 to rotate, so that the rotating rod 20 drives multiple gears 21 to rotate synchronously. Thus, multiple gears 21 mesh with multiple toothed plates 23 and rotate, so that the toothed plates 23 drive the slider 22 to move towards the side closer to the mold 5. Thus, the slider 22 pushes the cooled and solidified aluminum alloy to slide into the inside of the mold 5 and pushes it to one end of the conveyor belt 12, thereby completing the demolding of the cooled and solidified aluminum alloy.

[0039] Reference Figure 3 The grinding assembly of this embodiment includes a support block 27 mounted on the upper side of the front end of the conveyor belt 12, two cylinders 28 respectively fixed on opposite sides of the support block 27, two clamping blocks 29 respectively fixed on the output ends of the two cylinders 28, a third motor fixed on the middle of the upper side of the support block 27, and a grinding disc 30 fixed on the output end of the third motor. The grinding disc 30 is located above the conveyor belt 12. The unloading assembly of this embodiment includes a unloading port opened at the front end of the support block 27, a guide plate 31 fixed on the lower part of the front side of the unloading port, and a receiving box 32 located directly below the guide plate 31. The unloading port corresponds to the front end of the conveyor belt 12.

[0040] When grinding the cooled and solidified aluminum alloy, two cylinders 28 are activated. The output ends of the two cylinders 28 drive the two clamping blocks 29 to move closer to each other, thereby clamping and fixing the cooled and solidified aluminum alloy. Then, the third motor is activated. The output end of the third motor drives the grinding disc 30 to rotate, thereby grinding the clamped aluminum alloy. After grinding the cooled and solidified aluminum alloy, the conveyor belt 12 is activated. The conveyor belt 12 drives the ground aluminum alloy to move towards the side closer to the discharge port 28. Then, the ground aluminum alloy is guided into the receiving box 32 through the guide plate 31 for collection and storage.

[0041] Reference Figure 6In this embodiment, a condenser is fixed to the lower side of the front end of the second support platform 4, and air pipes are fixed to both sides of the condenser. One end of the air pipe corresponds to multiple molds 5. In this embodiment, sealing gaskets are fixed to the inner sides of the connecting block 25 and the slider 22, and the sealing gaskets correspond to both ends of the mold 5.

[0042] When liquid aluminum alloy is injected into multiple molds 5, two sealing gaskets seal the opposite ends of the molds 5 to prevent the liquid aluminum alloy from leaking out. Then, the condenser is activated, and the cold air in the condenser is sprayed through the air pipe to the periphery of the multiple molds 5. At this time, the liquid aluminum alloy in the multiple molds 5 is rapidly cooled down, which accelerates the cooling and solidification of the liquid aluminum alloy. At the same time, the rapid cooling causes the liquid aluminum alloy to shrink, which can be separated from the molds 5, making it convenient to demold the formed aluminum alloy in the future.

[0043] The above embodiments can be combined with each other.

[0044] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
