Description

Technical Field

[0001] This invention relates to the field of casting rod forming technology, specifically to an aluminum alloy casting rod forming apparatus. Background Technology

[0002] Aluminum alloys, with their low density, high specific strength, good thermal and electrical conductivity, and machinability, have been widely used in key fields such as aerospace, rail transportation, automobile manufacturing, and the electronics industry. Hot top casting is one of the important methods for forming aluminum alloys. In traditional hot top casting of aluminum alloys, the molten aluminum alloy is poured out of the melting furnace, passes through a degassing box and a filter box to reach the mold plate, and then through various distribution plates to reach the crystallizer. In the crystallizer, it is cooled by graphite rings and then pulled downwards by the ingot head.

[0003] Existing technologies are largely similar to a vertical, direct-water-cooled, semi-continuous multi-ingot casting system. The structure, disclosed in CN104014752B, includes a casting well, a casting machine, a casting machine transmission device, a melt transfer device that uses a siphon to transfer the molten material for casting ingots from the melting furnace to the casting furnace, and a casting platform capable of simultaneously casting multiple ingots. The melt transfer device includes a liquid guide pipe, a vacuum chamber, an electric vacuum source, and heating wires. This invention effectively improves ingot production efficiency, shortens ingot melting and casting time, and significantly saves on manpower, electricity, and material resources, thereby reducing production costs.

[0004] Existing devices primarily introduce molten aluminum alloy into the crystallizer from a height. This makes it difficult for some devices to allow the molten aluminum alloy in the storage tank to spontaneously rise and flow into the crystallizer, thus hindering the observation of the molten aluminum alloy level within the crystallizer. Secondly, some devices struggle to adjust the molten aluminum alloy level on the right side of the storage tank, making precise control of the molten aluminum alloy level in the crystallizer during casting difficult. Finally, some devices cannot adjust the flow rate of the molten aluminum alloy in the storage tank in real time based on the crystallizer's casting rod feed rate, making it difficult to adjust the flow rate of the molten aluminum alloy supplied to the crystallizer according to the cooling rate of different types of aluminum alloys, reducing the device's efficiency and practicality. Therefore, to solve these problems, an aluminum alloy casting rod forming device is proposed. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-8 One embodiment provided by the present invention:

[0035] An aluminum alloy casting rod forming device includes a first base 101, a guide channel 102 fixedly connected to the upper rear side of the first base 101, a control console 103 fixedly connected to the upper front side of the bottom plate of the first base 101, an overflow box 104 disposed below the overflow port on the left side of the guide channel 102, and a liquid storage tank 105 disposed below the discharge port on the left side of the guide channel 102.

[0036] A lead partition 309 is inserted in the middle of the inner wall of the liquid storage tank 105. A support frame 106 is fixedly connected to the top left side of the liquid storage tank 105. The bottom left side of the support frame 106 is fixedly connected to the top right side of the guide channel 102. A transmission box 107 is fixedly connected to the top of the support frame 106. An adjustment mechanism 3 is provided inside the transmission box 107.

[0037] A lead baffle 324 is inserted into the inner wall of the discharge port of the guide channel 102. A baffle valve port 325 is opened in front of the inside of the lead baffle 324. Sliding sleeves 326 are fixedly connected to the top two sides of the lead baffle 324. A limiting rod 327 is inserted into the inner wall of the sliding sleeve 326. The two ends of the limiting rod 327 are fixedly connected to the inside left side of the support frame 106. A drive box 328 is fixedly connected to the top of the lead baffle 324. An adjustment mechanism 4 is provided inside the drive box 328.

[0038] A second base 108 is installed on the right side of the liquid storage tank 105. A diversion plate 109 is fixedly connected to the top of the second base 108. The suction port at the left end of the diversion plate 109 is located inside the right side of the liquid storage tank 105. A crystallizer 110 is fixedly connected to the middle of the bottom of the diversion plate 109. A suction mechanism 2 is provided above the diversion plate 109.

[0039] The suction mechanism 2 includes a vacuum pump 201, the bottom of which is fixedly mounted in the middle of the top of the distribution plate 109. The suction port of the vacuum pump 201 is fixedly connected to an air pipe 202, and the other end of the air pipe 202 is fixedly connected to the exhaust port on the right side of the top of the distribution plate 109. This design allows the vacuum pump 201 to draw air from inside the distribution plate 109 through the air pipe 202. Due to the pressure difference between the inside and outside of the distribution plate 109, the molten aluminum alloy inside the storage tank 105 is drawn into the distribution plate 109 and filled into the crystallizer 110 under atmospheric pressure.

[0040] A venting channel 203 is located on the left side above the crystallizer 110 at the bottom of the distribution plate 109. An electric air valve 204 is fixedly connected to the left side of the venting channel 203. This design allows the electric air valve 204 to open the venting channel 203, ensuring that the pressure in the sealed space between the sealed distribution plate 109 and the crystallizer 110 is equal to atmospheric pressure. Based on the siphon principle, the melt level inside the crystallizer is kept consistent with the melt level on the right side inside the storage tank 105.

[0041] The crystallizer 110 has a cooling chamber 205 inside. A nozzle 206 is fixedly connected to the lower part of the cooling chamber 205. The nozzles 206 are arranged in a circular array on the lower inner wall of the crystallizer 110. A water pump 207 is fixedly connected to the upper right side of the cooling chamber 205. The top of the water pump 207 is fixedly connected to the bottom right side of the distribution plate 109. A graphite ring 208 is fixedly connected to the middle of the inner wall of the crystallizer 110. This design allows the water pump 207 to inject cooling water into the cooling chamber 205 and discharge it through the nozzles 206. The sprayed cooling water cools the solid aluminum alloy casting, while the cooling water flowing within the cooling chamber 205, in conjunction with the graphite ring 208, cools the liquid aluminum alloy casting.

[0042] The adjusting mechanism 3 includes a drive motor 301. The bottom of the drive motor 301 is fixedly connected to the top center of the transmission box 107. A drive shaft 302 is fixedly connected to the bottom center of the drive motor 301. The bottom end of the drive shaft 302 passes through the transmission box 107 and is fixedly connected to a first bevel gear 303. A second bevel gear 304 is meshed with the bottom of the first bevel gear 303. A transmission worm gear 305 is fixedly connected to the inner wall of the second bevel gear 304. The two ends of the transmission worm gear 305 are movably connected to both sides of the inner wall of the transmission box 107. Through this design, the drive motor 301 drives the drive shaft 302 and the first bevel gear 303 to rotate in a limited position, so that the first bevel gear 303 meshes and drives the second bevel gear 304 and the transmission worm gear 305 to rotate in a limited position.

[0043] A worm gear 306 is meshed with the outer right side of the worm gear 305. A worm screw 307 is fixedly connected to the inner wall of the worm gear 306. The top end of the worm screw 307 is movably connected to the top right side of the inner wall of the transmission box 107. The bottom end of the worm screw 307 passes through the support frame 106 and is threaded with a lifting screw cylinder 308. This design enables the worm gear 305 to mesh and drive the worm gear 306 to rotate, which in turn drives the worm screw 307 to rotate in a limited position. The outer wall of the lifting screw cylinder 308 is fixedly connected to the upper interior of the lead partition 309. The two sides of the outer wall of the lead partition 309 are in close contact with the limiting wheels 310. The central shaft of the limiting wheels 310 is movably connected to the right side of the inner wall of the support frame 106. This design enables the transmission screw 307 to drive the lifting screw 308 to slide up and down, which in turn causes the lifting screw 308 to drive the lead partition 309 to slide between the limiting wheels 310. This facilitates the control of the flow rate of the aluminum alloy melt from the left side of the storage tank 105 into the right side of the storage tank 105, thereby stabilizing the liquid level of the aluminum alloy melt on the right side of the storage tank 105.

[0044] A first infrared monitor 311 is fixedly connected to the top of the inner wall of the support frame 106 on the left side of the lead partition 309, and a second infrared monitor 312 is fixedly connected to the top of the inner wall of the support frame 106 on the right side of the lead partition 309. This design enables the first infrared monitor 311 and the second infrared monitor 312 to monitor the liquid level of the melt on both sides of the storage tank 105 in real time, and allows the monitoring data from the first infrared monitor 311 and the second infrared monitor 312 to be transmitted to the control console 103 via a data cable.

[0045] A linkage worm gear 321 is meshed with the left side of the outer wall of the transmission worm gear 305. A movable screw 322 is fixedly connected to the inner wall of the linkage worm gear 321. The top end of the movable screw 322 is movably connected to the top left side of the inner wall of the transmission box 107. The bottom end of the movable screw 322 passes through the support frame 106 and is threaded with a movable screw cylinder 323. The left side of the outer wall of the movable screw cylinder 323 is fixedly connected to the middle right side of the lead baffle 324. Through this design, the transmission worm gear 305 meshes and drives the linkage worm gear 321 and the movable screw 322 to rotate in a limited position, so that the movable screw 322 drives the movable screw cylinder 323 and the lead baffle 324 to slide up and down, which facilitates the control of the flow rate of aluminum alloy molten metal into the storage tank 105. At the same time, through the linkage lifting and lowering of the lead baffle 309 and the lead baffle 324, the liquid level of the aluminum alloy molten metal on the right side of the storage tank 105 can be stably maintained, which is conducive to the water-based crystallization and forming of aluminum alloy casting rods.

[0046] The adjustment mechanism 4 includes a servo motor 401. The left side of the servo motor 401 is fixedly connected to the right side of the drive housing 328. A movable worm gear 402 is fixedly connected to the middle of the left side of the servo motor 401. The left end of the movable worm gear 402 is movably connected to the left side of the inner wall of the drive housing 328. A movable worm wheel 403 is meshed with the front side of the outer wall of the movable worm gear 402. Through this design, the servo motor 401 can drive the movable worm gear 402 to rotate in a limited position, so that the movable worm gear 402 meshes with and drives the movable worm wheel 403 to rotate.

[0047] A rotating shaft 404 is fixedly connected to the inner wall of the movable worm gear 403. The top end of the rotating shaft 404 is movably connected to the top of the inner wall of the drive box 328. The bottom end of the rotating shaft 404 passes through the top edge of the lead baffle 324 and is fixedly connected to a lead valve plate 405. The width of the lead valve plate 405 is slightly larger than the width of the baffle valve port 325. Through this design, the movable worm gear 403 drives the rotating shaft 404 and the lead valve plate 405 to rotate in a limited position, so that the lead valve plate 405 can additionally control the flow rate of the melt flowing into the storage tank 105, thereby effectively controlling the difference in liquid level height between the two sides of the melt inside the storage tank 105.

[0048] Working Principle: When vacuum suction of molten aluminum alloy is required, at the start of casting, the electric air valve 204 is closed, causing the venting channel 203 to be closed, and the dummy ingot head is pressed against the lower edge of the crystallizer. First, the vacuum pump 201 is started via the control console 103. Due to the pressure difference inside and outside the distribution plate 109, the molten aluminum alloy is drawn into the distribution plate 109 under atmospheric pressure and fills the crystallizer 110. Then, the electric air valve 204 is started via the control console 103 to open the venting channel 203. According to the siphon principle, the liquid level in the crystallizer 110 should be consistent with the liquid level on the right side of the storage tank 105. At this time, the dummy ingot head begins to descend, and casting begins. This achieves the vacuum suction operation of the molten aluminum alloy.

[0049] When it is necessary to adjust the liquid level in the storage tank 105, the molten aluminum alloy is poured out from the tilting aluminum alloy melting furnace, flows through the guide channel 102, the storage tank 105, and the diversion plate 109 into the crystallizer 110. Firstly, the liquid level of the molten alloy on both sides of the storage tank 105 is monitored in real time by the first infrared monitor 311 and the second infrared monitor 312, and the monitoring data can be transmitted to the control console 103 via a data cable.

[0050] Then, the drive motor 301 is started via the control console 103. The drive motor 301 drives the transmission shaft 302 to rotate in a limited position. The transmission shaft 302 drives the first bevel gear 303 to rotate synchronously. The first bevel gear 303 meshes and drives the second bevel gear 304 to rotate. The second bevel gear 304 drives the transmission worm gear 305 to rotate in a limited position. The transmission worm gear 305 meshes and drives the transmission worm wheel 306 to rotate. The transmission worm wheel 306 drives the transmission screw 307 to rotate in a limited position. The transmission screw 307 drives the lifting screw barrel 308 to slide up and down. The lifting screw barrel 308 drives the lead partition 309 to slide up and down, thereby controlling the flow rate of the aluminum alloy melt from the left side of the storage tank 105 into the right side of the storage tank 105. At the same time, in conjunction with the forming speed of the aluminum alloy casting rod, the liquid level height of the aluminum alloy melt on the right side inside the storage tank 105 can be effectively controlled.

[0051] Simultaneously, the transmission worm gear 305 engages and drives the linkage worm wheel 321 to rotate. The linkage worm wheel 321 drives the movable screw 322 to rotate in a limited position. The movable screw 322 drives the movable screw barrel 323 to slide up and down. The movable screw barrel 323 drives the lead baffle 324 to slide synchronously, thereby controlling the flow rate of the aluminum alloy molten material into the storage tank 105. This, combined with the flow rate of the aluminum alloy molten material from the left side of the storage tank 105 into the right side, stably maintains the liquid level of the aluminum alloy molten material on the left side inside the storage tank 105. This achieves the adjustment operation of the liquid level in the storage tank 105.

[0052] When it is necessary to adjust the liquid level difference in the storage tank 105, the servo motor 401 is first started via the control console 103. The servo motor 401 drives the movable worm gear 402 to rotate to a limit position. The movable worm gear 402 engages and drives the movable worm wheel 403 to rotate. The movable worm wheel 403 drives the rotating shaft 404 to rotate to a limit position. The rotating shaft 404 drives the lead valve plate 405 to rotate synchronously. Thus, the lead valve plate 405 can additionally control the flow rate of the molten metal flowing into the storage tank 105, so that a stable height difference is formed between the liquid levels of the aluminum alloy molten metal on both sides inside the storage tank 105. This realizes the adjustment operation of the liquid level difference in the storage tank 105, and the operation ends here.
