Description

Technical Field

[0001] This invention relates to the field of aluminum alloy processing technology, specifically to an aluminum alloy casting barrel with preheating and heat preservation functions. Background Technology

[0002] Aluminum alloy casting is the core process in the production of precision aluminum alloy castings, and the casting jar is a key tool for transferring molten aluminum alloy. Most existing conventional casting jars adopt a single-layer steel structure or a composite structure with an inner asbestos insulation layer. Some improved products are also equipped with auxiliary structures such as lifting lugs and liquid level indicators inside the jar. The overall structure is simple and the manufacturing cost is low. It can meet the short-distance transfer needs of molten aluminum under normal production rhythm and is widely used in small and medium-sized foundry workshops.

[0003] However, the existing insulation solutions for casting ladles mentioned above all fall under the category of passive insulation. They rely solely on the insulating material to slow down heat loss and cannot actively compensate for temperature loss during the transfer of molten aluminum. When the transfer path is long, the ambient temperature is low, or the transfer time is increased due to fluctuations in production rhythm, the temperature of the molten aluminum is prone to falling below the threshold of the casting process, which can lead to casting defects such as cold shuts and insufficient pouring. At the same time, the bottom of the existing casting ladles is mostly a solid steel structure, which is in direct contact with the ground and forms an efficient heat conduction path, further accelerating the heat loss of the molten aluminum in the ladle. In addition, the uneven temperature distribution on the ladle wall can easily induce local oxidation of the molten aluminum. The resulting oxide scale is easy to adhere to the ladle wall, which will not only reduce the purity of the castings poured later, but also increase the frequency and cost of cleaning and maintenance of the ladle. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an aluminum alloy casting bucket with preheating and heat preservation functions, which solves the problems of cold shut-off of castings and insufficient pouring caused by existing casting buckets relying on the barrier effect of heat preservation materials to slow down heat loss.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy casting barrel with preheating and heat preservation function, comprising a casting barrel, a heat insulation chamber fixed to the lower side of the casting barrel, a fixing block fixed to the outside of the casting barrel, a rotating component disposed inside the fixing block, a limiting block one connected to the rotating component, a limiting block two fixed to the outside of the fixing block, the lower side of the limiting block one disposed above the limiting block two, a fixing bolt one threadedly connected to the inside of the limiting block one, the external thread of the fixing bolt one threadedly connected to the inside of the limiting block two, a lifting rod disposed inside the limiting block one and the limiting block two, a scale disposed inside the casting barrel, a heating power supply fixed inside the heat insulation chamber, a connecting wire and a switch electrically connected inside the heating power supply, a heating wire electrically connected to the outside of the connecting wire, the outside of the connecting wire disposed inside the casting barrel and the heat insulation chamber, and the outside of the heating wire disposed inside the casting barrel.

[0006] By adopting the above technical solution, firstly, the fixing bolts are loosened to separate the first limiting block from the second limiting block. The rotating component is used to rotate the first limiting block around the fixing block. After the lifting rod is placed between the two limiting blocks, it is reset and locked. Then, the switch is triggered to start the heating power supply. The current is transferred to the heating wire through the connecting wire to generate heat and preheat the inner wall of the casting tank. After the tank reaches the process temperature, molten aluminum alloy is injected and the liquid level is controlled according to the scale on the tank. The lifting rod is used to transfer the device to the casting area for pouring. The device adopts a double-layer stainless steel structure with an inner layer coated with a high-temperature resistant heat-insulating coating. Combined with the hollow structure of the bottom heat insulation chamber, it effectively blocks the heat conduction path between the bottom of the tank and the ground, slows down the temperature drop rate of the aluminum alloy liquid during the transfer process, prevents the generation of cold shut defects, and reduces the adhesion of oxide scale on the tank wall.

[0007] Preferably, the rotating assembly includes a first rotating column, which is externally fixedly connected to the inside of the fixed block, and a second rotating column is rotatably connected to the outside of the first rotating column, which is externally fixedly connected to the outside of the first limiting block.

[0008] Preferably, a fixed arm is provided on the outside of the casting barrel, a storage box is fixed on the outside of the fixed arm, and a transmission column is rotatably connected inside the storage box.

[0009] Preferably, a transmission arm one is fixedly connected to the outside of the transmission column, a transmission arm two is rotatably connected to the outside of the transmission arm one, a transmission arm three is provided inside the transmission arm one, a slider is fixed to the outside of the transmission arm three, a guide rail is fixed to the outside of the storage box, and the slider is slidably connected to the outside of the slider.

[0010] Preferably, the internal thread of the transmission arm three is connected to a fixing bolt two, and the external thread of the fixing bolt two is connected to a scraper or a connecting block, with the scraper externally located inside the casting barrel.

[0011] Preferably, a rotating shaft is fixedly connected inside the connecting block, and a brush roller is rotatably connected to the outside of the rotating shaft. The outside of the brush roller is disposed inside the casting barrel.

[0012] Preferably, the transmission column is externally fixedly connected with a locking block and a pointer, the storage box is internally fixedly connected with a blocking block, the lower side of the storage box is fixedly fixed with a nozzle, and the storage box is internally equipped with a speed regulating component.

[0013] Preferably, the bottom surface of the card block is located on the upper side of the first blocking block, and the external part of the transmission column is rotatably connected to the inside of the first blocking block.

[0014] Preferably, the speed regulating component includes a second rotating shaft, which is rotatably connected to the inside of the storage box. A second positioning block is fixed to the outside of the storage box, and a second blocking block is fixed to the outside of the second rotating shaft. The outside of the second blocking block is located inside the storage box. A first positioning block is located to the outside of the second rotating shaft. A slot is formed inside the second positioning block, and an installation block is fixed to the outside of the first positioning block.

[0015] Preferably, the exterior of the mounting block is disposed inside the positioning block two and the slot.

[0016] This invention provides an aluminum alloy casting tank with preheating and heat preservation functions. It has the following beneficial effects: 1. This invention solves the problem of rapid heat loss in casting barrels by combining a hollow structure with an embedded heating wire and an insulation chamber inside the casting barrel, along with electric heating from a power supply. The casting barrel adopts a double-layer stainless steel structure with an inner layer coated with a high-temperature resistant insulation coating. The bottom insulation chamber blocks the heat conduction path from contact with the ground. This design alleviates the temperature drop of the aluminum alloy liquid during the transfer process, avoids cold shut defects caused by excessively low temperatures, and reduces the adhesion of oxide scale to the barrel wall, thereby improving the quality of the castings.

[0017] 2. The present invention achieves quick assembly, disassembly and storage of the lifting rod by means of a rotating component in conjunction with a limiting block one and a limiting block two; while the rotating structure formed by rotating column one and rotating column two allows the limiting block one to rotate flexibly, which, together with the fixing bolt one, ensures the structural stability during the lifting process, facilitates the storage and transportation of the equipment, and improves the storage and portability of the device.

[0018] 3. This invention integrates cleaning and coating functions by linking the transmission column with the transmission arm one, transmission arm three, and slider, along with replaceable scrapers and brush rollers. After the pouring operation, the scraper can be used to scrape off the residual oxide scale and damaged coating along the barrel wall trajectory. When replaced with a brush roller, the thermal insulation coating can be evenly rolled onto the barrel wall simultaneously, reducing pouring impurities and ensuring the integrity of the thermal insulation coating and the consistency of the thermal insulation effect.

[0019] 4. This invention achieves precise control of the amount of paint sprayed by cooperating with the second shielding block and the first positioning block in the speed regulating component; by rotating the second rotating shaft to adjust the opening of the second shielding block, and by the mounting block being fixed by engaging the slots at different positions, the user can precisely control the feeding speed and the amount of paint used according to the rotation angle indicated by the pointer; this design ensures the uniformity of the insulation coating thickness, avoids paint waste, and further guarantees the stability of the insulation performance of the casting barrel.

[0022] The technical solution 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.

[0023] like Figure 1 - Figure 4As shown, this embodiment of the invention provides an aluminum alloy casting barrel with preheating and heat preservation functions, including a casting barrel 1, a heat insulation chamber 2 fixed to the lower side of the casting barrel 1, a fixing block 3 fixed to the outside of the casting barrel 1, a rotating component 4 disposed inside the fixing block 3, a limiting block 5 connected to the rotating component 4, a limiting block 6 fixed to the outside of the fixing block 3, the lower side of the limiting block 5 disposed above the limiting block 6, a fixing bolt 7 threadedly connected inside the limiting block 5, and the external thread of the fixing bolt 7 threadedly connected to the inside of the limiting block 6, a lifting rod 8 disposed inside the limiting block 5 and the limiting block 6, a scale 9 disposed inside the casting barrel 1, a heating power supply 10 fixed inside the heat insulation chamber 2, a connecting wire 11 and a switch 13 electrically connected inside the heating power supply 10, a heating wire 12 electrically connected to the outside of the connecting wire 11, the outside of the connecting wire 11 disposed inside the casting barrel 1 and the heat insulation chamber 2, and the outside of the heating wire 12 disposed inside the casting barrel 1.

[0024] Specifically, first, tighten the fixing bolt 7 to separate the limiting block 5 and the limiting block 6. Then, lift the limiting block 5, which rotates around the fixing block 3 via the rotating assembly 4. Place the lifting rod 8 between the limiting block 5 and the limiting block 6. Then, reset the limiting block 5, the limiting block 6, and the fixing bolt 7 to fix the lifting rod 8. Next, press the switch 13 to start the heating power supply 10. The heating power supply 10 transmits current to the heating wire 12 through the connecting wire 11, thereby heating the heating wire 12. At this time, the heating wire 12 heats the inner layer of the casting barrel 1. When it is heated to a certain temperature, pour the molten aluminum alloy from the top of the casting barrel 1, and observe the relative position of the liquid level and the scale 9. When the liquid level reaches... Upon reaching the designated position, the addition of aluminum alloy is stopped, and the user lifts the lifting lever 8 to bring the pouring bucket 1 to the pouring area for pouring. The pouring bucket 1 has a double-layer structure, with a high-temperature resistant heat-insulating coating on the inner surface that contacts the aluminum alloy. This heat-insulating coating is existing technology and will not be described in detail here. The interior of the heat insulation chamber 2 is hollow, which prevents the bottom of the pouring bucket 1 from directly contacting the ground, thereby preventing the heat of the aluminum alloy from being lost from the ground. The combination of the double-layer heat insulation structure and the hollow structure, and the fact that the pouring bucket 1 and the heat insulation chamber 2 are made of stainless steel, can alleviate the problem of the aluminum alloy cooling down too quickly during pouring, avoid cold shuts, and reduce the adhesion of oxide scale to the surface of the pouring bucket 1.

[0025] like Figure 4 The rotating assembly 4 includes a rotating column 41, which is externally fixedly connected to the inside of the fixed block 3. A rotating column 42 is rotatably connected to the outside of the rotating column 41, and the rotating column 42 is externally fixedly connected to the outside of the limiting block 5.

[0026] Specifically, pulling the limiting block 5 causes the rotating column 42 to rotate around the rotating column 41. Then the limiting block 5 separates from the limiting block 6 and releases the lifting rod 8, making it convenient for users to install and remove the lifting rod 8, thus improving the storage and portability of the device.

[0027] like Figure 1 , Figure 5 and Figure 6 The casting tank 1 is provided with a fixed arm 14 on the outside, and a storage box 15 is fixed to the outside of the fixed arm 14. A transmission column 16 is rotatably connected inside the storage box 15. A transmission arm 17 is fixedly connected to the outside of the transmission column 16. A transmission arm 28 is rotatably connected to the outside of the transmission arm 17. A transmission arm 39 is provided inside the transmission arm 17. A slider 20 is fixed to the outside of the transmission arm 39. A guide rail 31 is fixed to the outside of the storage box 15. The slider 20 is slidably connected to the outside of the slider 20. A fixing bolt 21 is threadedly connected inside the transmission arm 39. A scraper block 22 or a connecting block 23 is threadedly connected to the outside of the fixing bolt 21. The scraper block 22 is located inside the casting tank 1.

[0028] Specifically, after pouring, the transmission arm 19 is first inserted into the groove inside the transmission arm 17 by the protrusion on the top of the transmission arm 19 for installation. Then, the transmission arm 18 is pulled to push the transmission arm 17 to rotate. Subsequently, the transmission column 16 rotates inside the storage box 15 under the drive of the transmission arm 17, and the transmission arm 19 rotates synchronously under the drive of the transmission arm 17. The 20 rotates along the inside of the 31 under the drive of the 19 to ensure that the 19 rotates along a fixed trajectory. Since the scraper 22 is connected to the transmission arm 19 by the fixing bolt 21, the scraper 22 rotates along the inner wall of the pouring barrel 1 under the drive of the transmission arm 19. At this time, the scraper 22 scrapes off the oxide scale and damaged coating left after pouring on the inner wall of the pouring barrel 1, thereby achieving the effect of regularly cleaning the impurities inside the pouring barrel 1, reducing pouring impurities and improving pouring quality.

[0029] like Figure 5 and Figure 6 The connecting block 23 is fixedly connected to a rotating shaft 24, and the rotating shaft 24 is rotatably connected to a brush roller 25. The brush roller 25 is located inside the casting barrel 1.

[0030] Specifically, by tightening the fixing bolt 21, the scraper 22 is removed from the transmission arm 3 19. Then, the scraper 22 is replaced with the connecting block 23, and the brush roller 25 inside the connecting block 23 is attached to the inner wall of the casting tank 1. At the same time, the coating that makes up the heat insulation coating is sprayed onto the inner wall of the casting tank 1. Then, the transmission arm 2 18 is pulled to drive the transmission arm 1 17 and the transmission arm 3 19 to rotate. Then, the transmission arm 3 19 drives the connecting block 23 to rotate through the fixing bolt 21. After that, the connecting block 23 drives the brush roller 25 to rotate along the inner wall of the casting tank 1 through the rotating shaft 1 24. The brush roller 25 rotates around the rotating shaft 1 24 at the same time. Then, the coating is evenly rolled by the brush roller 25 to form a new complete coating, thereby achieving the effect of timely repair of the complete coating.

[0031] like Figure 7 and Figure 8 The transmission column 16 is externally fixedly connected to a locking block 27 and a pointer 28. A blocking block 29 is internally fixedly connected to the storage tank 15. A nozzle 26 is fixedly fixed to the lower side of the storage tank 15. A speed regulating component 30 is installed inside the storage tank 15. The bottom surface of the locking block 27 is located on the upper side of the blocking block 29. The transmission column 16 is externally rotatably connected to the inside of the blocking block 29. The speed regulating component 30 includes a rotating shaft 301, which is externally rotatably connected to the storage tank 16. Inside 5, a second positioning block 304 is fixed to the outside of the storage box 15, a second blocking block 302 is fixed to the outside of the rotating shaft 301, the outside of the blocking block 302 is located inside the storage box 15, a first positioning block 303 is located outside the rotating shaft 301, a slot 305 is opened inside the second positioning block 304, and an installation block 306 is fixed to the outside of the first positioning block 303; the outside of the installation block 306 is located inside the second positioning block 304 and the slot 305.

[0032] Specifically, after the coating is scraped off, the second transmission arm 18 is rotated to drive the first transmission arm 17 and the transmission column 16 to rotate. Then, the pointer 28 rotates synchronously under the drive of the transmission column 16. The pointer 28 and the locking block 27 rotate synchronously through the transmission column 16, allowing the pointer 28 to determine whether the locking block 27 covers the notch in the first blocking block 29. First, the locking block 27 is controlled to cover the notch. Then, a measured amount of coating is poured into the storage tank 15 through the inlet. Next, the positioning block 303 is pulled to disengage the mounting block 306 from the slot 305. Then, the positioning block 303 is rotated to rotate the second blocking block 302. The positioning block 304 has a notch... With the same slot 305, when the positioning block 1 303 rotates to the required angle, pressing the positioning block 1 303 causes the mounting block 306 to snap into the new slot 305. At this time, the shielding block 2 302 and the positioning block 1 303 rotate synchronously. The user can control the exposed discharge port of the shielding block 2 302 by controlling the rotation angle of the shielding block 2 302, thereby controlling the discharge speed of the paint. Then the paint enters the nozzle 26 and is evenly sprayed into the interior of the pouring tank 1. Subsequently, the paint is evenly coated into the interior of the pouring tank 1 by the brush roller 25, thereby enabling the user to easily control the amount of paint and the spraying speed, ensuring the uniform thickness of the insulation coating, and thus ensuring a consistent and uniform insulation effect.

[0033] Working principle: First, unscrew the fixing bolt 7. Then, rotate the rotating column 42 in the rotating assembly 4 around the rotating column 41 to flip the limiting block 5. Place the lifting rod 8 between the limiting block 5 and the limiting block 6, and then reset and lock it. Then, turn on the switch 13. The heating power supply 10 drives the heating wire 12 embedded in the pouring tank 1 to heat up through the connecting wire 11. Combined with the double-layer stainless steel structure and the hollow blocking design of the bottom heat insulation chamber 2, the tank body is preheated and kept warm. When pouring molten aluminum alloy into the tank, the liquid level is controlled according to the scale 9. After being transferred to the pouring area, the pouring is completed by lifting the rod 8. After the pouring operation, the scraper 22 with the fixing bolt 21 is installed on the transmission arm 19. The transmission arm 18 is rotated to drive the transmission column 16 and the transmission arm 17 in a coordinated manner, so that the scraper 22 scrapes off the oxide scale and damaged coating along the barrel wall trajectory. Then, it is replaced with the connecting block 23 equipped with the brush roller 25. At the same time, the rotating shaft 301 in the speed regulating component 30 is rotated to adjust the opening of the shielding block 302. The opening is fixed by the cooperation of the mounting block 306 and different slots 305. The amount of paint sprayed from the nozzle 26 in the storage box 15 is controlled by the cooperation of the pointer 28 and the card block 27. The transmission mechanism then drives the brush roller 25 to evenly roll the paint onto the barrel wall, realizing the repair and regeneration of the heat insulation coating, thus completing the whole cycle operation from preheating, pouring to self-cleaning maintenance.

[0034] It will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
