Description

Technical Field

[0001] This invention belongs to the field of aluminum rod casting technology, specifically an aluminum alloy round rod casting equipment. Background Technology

[0002] Aluminum rods are rod-shaped metal materials made from aluminum or aluminum alloys. They are lightweight, corrosion-resistant, have good electrical and thermal conductivity, and are easy to process. They are widely used in aerospace, automotive, construction, electronics, and machinery manufacturing industries. Aluminum rod casting refers to the process of pouring molten aluminum or aluminum alloy liquid into a mold through a specific process, and then cooling and solidifying it to form a rod-shaped blank. Aluminum rod casting is divided into processing steps such as melting, aluminum liquid purification, and semi-continuous casting. After the aluminum melt is melted, it needs to flow continuously into the mold through a chute. After the crystallizer cools and shapes the aluminum melt, the shaped aluminum rod is slowly pulled out while being cast by the traction device equipped at the bottom of the mold. When the aluminum melt flows into the mold, it usually needs to be purified to filter out impurities. In existing technologies for filtering molten aluminum, a large number of bubbles are easily generated when the molten aluminum comes into contact with air during the filtration process, resulting in numerous depressions in the center and surface of the aluminum rod, which reduces the quality of the aluminum rod casting. Therefore, this invention provides an aluminum alloy round rod casting equipment. Summary of the Invention

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] like Figures 1 to 6 As shown, an aluminum alloy round bar casting equipment according to an embodiment of the present invention includes a processing box 4. The interior of the processing box 4 is equipped with an active component 8 for cleaning impurities floating on the surface of the molten aluminum. Below the active component 8 is a gas supply component 10 for introducing inert gas into the molten aluminum. The active component 8 includes a filter plate 803 and a push rod 808. A folded plate 807 is fixedly connected to the lower part of the push rod 808, and the folded plate 807 is L-shaped. The filter plate 803 rotates to collect and filter impurities floating on the surface of the molten aluminum. (See attached diagram.) Figure 4 As shown, multiple filter plates 803 are provided, and the filter plates 803 are arc-shaped; The gas supply assembly 10 includes a rotating sleeve 1004, on one side of which a rotating jet disk 1002 is fixedly connected. The push rod 808 moves up and down, driving the rotating sleeve 1004 to rotate in both directions via a folding plate 807. The rotation of the rotating sleeve 1004 in both directions drives the rotating jet disk 1002 to rotate and introduce inert gas into the molten aluminum. A meshing strip is installed at the position where the side of the folding plate 807 contacts the surface of the rotating sleeve 1004, and a meshing groove is formed on the surface of the rotating sleeve 1004.

[0020] This invention takes into account that during the flow of molten aluminum in the flow channel, a large amount of air may be entrained, resulting in a large number of bubbles inside the molten aluminum. Furthermore, the direct contact between the molten aluminum and the external air during the flow will cause a large number of impurities to be entrained, reducing the quality of aluminum rod casting. Therefore, by spraying inert gas from inside the rotating jet disk 1002 in a forward and reverse rotation manner, the bubbles and impurities inside the molten aluminum come into contact with the inert gas and float on the surface of the molten aluminum. Since the filter plate 803 is arc-shaped, the rotation of the filter plate 803 can scrape the gas floating on the surface of the molten aluminum. After filtering the molten aluminum, the impurities will adhere to the surface of the filter plate 803. It should be noted that the up-and-down movement of the push rod 808 will drive the bending plate 807 to move up and down. When the bending plate 807 moves, it will drive the meshing bar to engage with the meshing groove opened on the surface of the rotating sleeve 1004, thereby driving the rotating sleeve 1004 to rotate in both directions. The rotation of the rotating sleeve 1004 can drive the rotating jet disk 1002 to rotate in both directions, so that the inert gas is continuously injected and rotated in both directions to be introduced into the aluminum liquid. The rotation of the rotating jet disk 1002 can not only change the way and state of the inert gas being ejected, but also, to a certain extent, make the ejected inert gas fully mixed with the aluminum liquid, thereby removing bubbles and impurities in the aluminum liquid, improving the cleanliness of the aluminum liquid, and thus improving the quality of aluminum rod casting.

[0021] like Figures 4 to 6 As shown, the active component 8 also includes a first motor 801 fixedly installed on the side of the processing box 4. The output end of the first motor 801 is fixedly connected to a drive shaft 802. The filter plate 803 is detachably installed on the surface of the drive shaft 802. A push plate 804 is fixedly connected to the surface of the drive shaft 802. The push plate 804 is triangularly arranged. The upper end of the push rod 808 slides in contact with the surface of the push plate 804. Several wedge grooves are opened on the surface of the filter plate 803 at a position away from the axis of the drive shaft 802.

[0022] During operation, when the molten aluminum flows to the area below the filter plate 803, with the introduction of inert gas, bubbles and impurities in the molten aluminum will float to the surface. It should be noted that initially, the molten aluminum level is below the axis of the drive shaft 802, and as the drive shaft 802 rotates, the filter plate 803 just scrapes against the surface of the molten aluminum. At this time, the first motor 801 drives the drive shaft 802 to rotate, which in turn drives the filter plate 803 to rotate. Because the surface of the filter plate 803, away from the axis of the drive shaft 802, has several wedge grooves, when the filter plate 803 comes into contact with the bubbles and impurities floating on the surface of the molten aluminum... Upon contact, the filter plate 803 gathers and collects air bubbles through the wedge groove. As the filter plate 803 rotates out of the aluminum molten surface with the rotation of the drive shaft 802, the air bubbles gradually burst, and impurities are collected inside the filter plate 803, filtering the aluminum molten material. The filtered impurities adhere to the surface of the filter plate 803. When one of the filter plates 803 rotates to the top, the impurities flow to the position of the filter plate 803 closest to the axis of the drive shaft 802. This prevents impurities from falling from the surface of the filter plate 803 into the aluminum molten material during continuous rotation, thus preventing secondary contamination of the aluminum molten material. It should be noted that when the drive shaft 802 drives the push plate 804 to rotate, the push plate 804 will intermittently push the push rod 808 to move downward. The movement of the push rod 808 drives the folding plate 807 to move up and down. The movement of the folding plate 807 can drive the rotating jet plate 1002 to rotate and spray inert gas through the rotating sleeve 1004. This can prevent the rotating jet plate 1002 from continuously rotating and spraying inert gas in one direction, thereby forming a backflow inside the aluminum liquid. This causes impurities that are not collected by the filter plate 803 and float on the surface of the aluminum liquid to return to the aluminum liquid, causing the impurities to flow back and forth, which affects the cleaning effect of impurities in the aluminum liquid. It should be reiterated that when the pusher plate 804 rotates 120°, the pusher rod 808 is pushed downward, causing the folding plate 807 to move downward. When the pusher plate 804 stops pushing the pusher rod 808 downward, the pusher rod 808, under the action of the return spring on its surface, causes the folding plate 807 to move upward, thereby causing the rotating sleeve 1004 to reverse. This effectively maintains the continuity of the folding plate 807 driving the rotating sleeve 1004 in both forward and reverse rotation. Furthermore, through the linkage of the forward and reverse air jetting of the rotating jet plate 1002 and the rotation of the filter plate 803 for impurity collection and bubble treatment, the aluminum liquid can be effectively filtered, improving the cleanliness of the aluminum liquid in the subsequent casting process.

[0023] like Figures 4 to 6As shown, the air supply assembly 10 also includes an air compressor 1001 fixedly installed on the side of the processing box 4. The output end of the air compressor 1001 is connected to the inside of the rotating sleeve 1004. A side plate 13 is rotatably connected to the surface of the rotating sleeve 1004. The side plate 13 is fixedly connected to the processing box 4. The folded plate 807 slides inside the side plate 13. An arc plate 1003 is fixedly connected to one side of the rotating jet disk 1002, and the side of the arc plate 1003 is arc-shaped. A fixing plate 805 is fixedly connected to the surface of the push rod 808. A scraper 806 is detachably connected to one end of the fixing plate 805. A partition 11 slides on the side of the scraper 806. A filter screen is installed below the partition 11. The partition 11 is detachably connected to the processing box 4.

[0024] During operation, since the molten aluminum is continuously supplied, some impurities inevitably remain unremoved. Therefore, a baffle 11 is installed. After the surface impurities are filtered and collected by the rotating filter plate 803, the filter plate 803 is inserted into the molten aluminum, propelling it forward. The filtered molten aluminum then flows towards the baffle 11 under the rotating action of the filter plate 803, causing it to flow out from below the baffle 11. If any untreated impurities remain in the molten aluminum, the filter screen below the baffle 11 will filter them, ensuring that the molten aluminum flowing through the baffle 11 is properly filtered. The molten aluminum continues to flow in a highly clean state. At this time, the push rod 808 moves up and down, which drives the fixed plate 805 to move. The movement of the fixed plate 805 causes one side of the scraper 806 to slide into contact with the bottom of the partition 11, thereby wiping the surface of the filter screen below the partition 11. This can effectively prevent impurities from clogging the filter screen and affecting the outflow of molten aluminum. The filtration design can prevent impurities that have not been fully filtered from flowing out directly, and can keep the impurities in the area below the filter plate 803 for continuous cleaning by the filter plate 803, thereby achieving the effect of thoroughly cleaning the impurities. It should be noted that after the scraper 806 moves up and down to scrape the filter screen below the baffle 11, the impurities on the surface of the filter screen will be scraped off by the scraper 806. The movement of the filter plate 803 on the molten aluminum will cause the molten aluminum to flow back and forth, and the scraped-off impurities will be drawn into the molten aluminum. At the same time, the flowing molten aluminum will also wash the filter screen below the baffle 11 to a certain extent. Some of the impurities on the filter screen will be separated from the filter screen under the action of the molten aluminum. Then, the scraped-off impurities and the impurities washed off will be carried back by the flow of molten aluminum. The molten aluminum flows down to the bottom of filter plate 803. At this time, the continuous rotation of filter plate 803 can process the backflowing impurities. The molten aluminum flowing down to the bottom of baffle plate 11 is pushed by the rotation of filter plate 803. After impacting and driving the impurities, most of the molten aluminum will flow out through the filter screen. Because the filter screen has a large number of mesh holes, it can not only prevent the molten aluminum from flowing out rapidly and in large quantities after the filter plate 803 pushes the molten aluminum, thus preventing the re-entry of air, but also effectively protect the high-purity molten aluminum, and further improve the effect of molten aluminum treatment.

[0025] like Figures 1 to 4 As shown, a backflow plate 12 is fixedly connected below the partition 11, an injection port 7 is fixedly connected above the processing box 4, an inclined plate is provided below the injection port 7, and a guide groove is opened on the surface of the inclined plate. The two sides of the side plate 13 are fixedly connected to the backflow plate 12 and the inclined plate respectively. The surface of the backflow plate 12 is arc-shaped, and the processing box 4 is provided with an outlet on one side of the backflow plate 12.

[0026] During operation, when molten aluminum flows from the flow channel into the processing tank 4, it first passes through the injection port 7. At this time, the molten aluminum flows towards the bottom of the filter plate 803 under the guidance of the injection port 7 and the inclined plate. When the molten aluminum flows, it will slowly flow downward under the guidance of the flow guide channel to avoid the rapid flow of the molten aluminum from the flow channel and the entrainment of a large amount of air, thereby reducing the generation of bubbles. It should be noted that when the molten aluminum flows from the filter screen below the partition plate 11 to the surface of the backflow plate 12, the backflow plate 12 guides the filtered molten aluminum to prevent the molten aluminum from falling directly and entraining air and generating bubbles, which can effectively improve the cleanliness of the molten aluminum.

[0027] like Figures 7 to 8 As shown, the interior of the processing box 4 is also equipped with a stirring assembly 14 for fully mixing the inert gas introduced into the molten aluminum. The stirring assembly 14 includes a second motor 1401. The output end of the second motor 1401 is fixedly connected to a rotating shaft 1402. Two sets of auxiliary cams 1403 are fixedly connected to the surface of the rotating shaft 1402. The surfaces of the two sets of auxiliary cams 1403 are provided with arc grooves arranged in opposite directions. A sliding column 1404 slides in contact with the arc groove on the surface of the auxiliary cam 1403. A stirring plate 1405 is fixedly connected above the sliding column 1404.

[0028] The present invention also considers that when the rotating jet disk 1002 sprays inert gas into the molten aluminum through forward and reverse rotation, even though the rotation of the rotating jet disk 1002 can stir the inert gas in the molten aluminum to a certain extent, in order to fully contact the inert gas with the molten aluminum, the rotation of the second motor 1401 drives the rotating shaft 1402 to rotate. The rotation of the rotating shaft 1402 drives the auxiliary cam 1403 to rotate. The rotation of the auxiliary cam 1403 drives the sliding column 1404 to move back and forth through the arc groove opened on the surface. At this time, the movement of the sliding column 1404 can drive the stirring plate 1405 to move in the molten aluminum. When the rotating jet disk 1002 sprays out the inert gas, a large number of bubbles will be generated in the molten aluminum. At this time, the stirring plate 1405 can drive the inert gas to move in the molten aluminum during the movement, so that the bubbles are dispersed, thereby allowing the molten aluminum to fully contact the inert gas, which can further clean the impurities and bubbles in the molten aluminum, and make them float on the top of the molten aluminum, which can effectively improve the purification effect of the molten aluminum. It should be noted that when the stirring plate 1405 moves, it not only allows the inert gas to come into full contact with the molten aluminum, but also pushes the molten aluminum. When impurities and bubbles float upward, the movement of the stirring plate 1405 will cause the impurities and bubbles to float evenly, thereby improving the floating efficiency of bubbles, and thus improving the cleaning efficiency of impurities and the cleanliness of the molten aluminum.

[0029] like Figures 7 to 8 As shown, a mating rod 1406 is movably connected to one side of the stirring plate 1405 via a hinge ball. One end of the mating rod 1406 is in sliding contact with the arc surface of the arc disk 1003. A support rod is provided between the mating rod 1406 and the side plate 13, and the mating rod 1406 and the support rod are slidably connected. The rotating shaft 1402 is rotatably connected to the side plate 13.

[0030] During operation, when the assist cam 1403 moves the stirring plate 1405 above the sliding column 1404 via the arc groove, the movement of the stirring plate 1405 will cause the connecting rod 1406 to extend and retract. When the stirring plate 1405 moves to a position close to the arc disk 1003, the connecting rod 1406 stops extending and retracting and will push the sliding column 1404 below the stirring plate 1405 to rotate via the hinge ball, thereby causing the stirring plate 1405 to rotate and change its tilt direction. When the assist cam 1403 continues to move the stirring plate 1405 away from the arc disk 1003, the movement of the stirring plate 1405 will push the aluminum liquid moving towards the arc disk 1003 in the opposite direction. On the one hand, this allows the impurities inside the aluminum liquid to float to the top more evenly, and on the other hand, it can prevent the aluminum liquid from generating a large number of bubbles due to stirring, which would prevent it from fully contacting the inert gas, thus effectively improving the cleaning effect of impurities. It should be noted that, since the side of the arc disk 1003 is arc-shaped, when the arc disk 1003 and the rotating jet disk 1002 are rotating, the stirring plate 1405 will be continuously pushed by the cooperating rod 1406 and will swing back and forth during the movement. When the stirring plate 1405 is close to the position of the arc disk 1003, the stirring plate 1405 will change its tilt direction and continue to swing during the movement, which can further mix the aluminum liquid and the inert gas, thereby further improving the purification effect of the aluminum liquid.

[0031] like Figures 9 to 10 As shown, the interior of the processing chamber 4 is also equipped with an auxiliary component 9 for protecting the filtered aluminum liquid. The auxiliary component 9 includes an air chamber 901 fixedly installed above the processing chamber 4. The output end of the air chamber 901 is connected to a jet hood 902. The interior of the jet hood 902 is rotatably connected to multiple sets of swing plates 904 via pins. One set of swing plates 904 is rotatably connected to two ends of a telescopic rod 903. The other end of the telescopic rod 903 is detachably connected to a baffle 905. One end of the baffle 905 is in sliding contact with the arc surface of the backflow plate 12.

[0032] During operation, when the filtered molten aluminum flows out from the backflow plate 12, the power source for the outflow of molten aluminum is the turning force of the filter plate 803. To prevent the molten aluminum from flowing out quickly from the filter screen below the partition plate 11 and not flowing out in a central stream, the air chamber 901 is activated before the molten aluminum flows out to spray inert gas through the jet hood 902 onto the surface of the outflowing molten aluminum. This prevents the molten aluminum from flowing quickly from the surface of the backflow plate 12 and re-entraining air, causing the formation of bubbles. When the molten aluminum flows out instantaneously, it will push the baffle 905 to swing. The swing of the baffle 905 will push the telescopic rod 903 to extend and retract while swinging slightly. At this time, the swing of the telescopic rod 903 can drive multiple sets of swing plates 904 to swing slightly inside the jet hood 902 through the pin shaft. This ensures that the swing plates 904 always point towards the surface of the molten aluminum flowing out from the backflow plate 12, protecting the molten aluminum and effectively preventing multiple streams of molten aluminum from re-entraining air before they converge. It should be noted that since multiple sets of swing plates 904 are movably connected by hinged rods, when the telescopic rod 903 drives one set of swing plates 904 to swing slightly via the pin, multiple sets of swing plates 904 will rotate. After the multiple streams of molten aluminum slowly converge, the swing plates 904 will be reset under the reverse force of the compression spring, so that the baffle 905 continues to contact the arc surface of the backflow plate 12, thus reciprocating. This fully protects the purified molten aluminum, thereby improving the quality of the molten aluminum in the subsequent casting of aluminum rods.

[0033] like Figures 1 to 2 and Figure 11As shown, a base 1 is provided below the processing box 4, a mold plate 2 is rotatably provided above the processing box 4, a diverter plate 6 is fixedly installed on the upper surface of the mold plate 2, multiple crystallizers 3 are installed on the lower surface of the mold plate 2, a lifting platform 16 is slidably connected inside the base 1, winches 15 are provided on both sides of the lifting platform 16, a traction machine 5 is provided above the lifting platform 16, multiple round top columns are provided inside the traction machine 5, and two sets of hydraulic cylinders are provided between the mold plate 2 and the base 1.

[0034] During the casting process, two sets of hydraulic cylinders first rotate the mold plate 2, which in turn rotates the diversion plate 6 and the crystallizer 3 by 90°. At this time, the bottom of the crystallizer 3 is in close contact with the circular top column inside the traction machine 5. After the diversion plate 6 rotates, one end will be inserted into the outlet position opened on one side of the processing box 4 and closely fit with one end of the backflow plate 12. After the processed aluminum liquid flows through the backflow plate 12 to the outlet of the processing box 4, it will continue to flow into the interior of the diversion plate 6. Then, the aluminum liquid will be processed by the crystallizer 3 below the mold plate 2 to form an aluminum rod, thus completing the forming of the aluminum rod. When the aluminum rod is slowly forming, the winch 15 is started to drive the lifting platform 16 to move downward inside the base 1, so that the circular top column pulls out the formed aluminum rod to reach the required casting length, thus completing the casting of the aluminum rod.

[0035] like Figures 3 to 6 As shown, the side of the fixed plate 805 is slidably connected to the inner wall of the processing box 4. The rotating jet disk 1002 is internally connected to the rotating sleeve 1004. The rotating jet disk 1002 is equipped with a backflow valve to prevent the aluminum liquid from flowing back. Both the rotating jet disk 1002 and the filter plate 803 are made of high-temperature resistant materials. The folded plate 807 below the push rod 808 is slidably connected to the side plate 13.

[0036] During operation, the aerator 1001 delivers inert gas through the rotating sleeve 1004 to the rotating jet disk 1002, and then sprays it from the rotating jet disk 1002 into the molten aluminum flowing into the processing tank 4. The gas reacts with the bubbles and impurities inside the molten aluminum, causing the impurities and bubbles to float upwards, making it easier for the filter plate 803 to clean and collect the impurities on the surface of the molten aluminum. Furthermore, a reflux valve is installed inside the rotating jet disk 1002 to prevent molten aluminum from flowing into the interior of the rotating jet disk 1002 and causing damage to it.

[0037] like Figures 9 to 10 As shown, the swing plates 904 are movably connected by hinge rods. One side of one set of swing plates 904 is provided with multiple sets of compression springs between it and the jet hood 902. The jet hood 902 is located directly above the backflow plate 12. The baffle 905 is also made of a high-temperature resistant material.

[0038] During operation, when multiple streams of molten aluminum flow out from the backflow plate 12, the molten aluminum is propelled by the filter plate 803, which in turn creates an impact force on the baffle 905, causing the baffle 905 to slide on the surface of the backflow plate 12. This changes the direction of the swing plate 904, allowing the inert gas to be sprayed evenly along with the flow of molten aluminum, thus protecting the molten aluminum. This effectively improves the cleanliness of the molten aluminum as it flows into the diversion plate 6, facilitating the protection of the molten aluminum and improving the quality of subsequent aluminum rod casting.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
