Description

Technical Field

[0001] This utility model belongs to the technical field of magnesium alloy material preparation equipment, and in particular relates to a magnesium alloy rapid solidification control device. Background Technology

[0002] Magnesium alloys, with their low density, high specific strength, and good shock absorption properties, are increasingly in demand in high-end manufacturing fields such as aerospace, transportation, and electronic communications. Rapid solidification technology, as a core means to optimize the microstructure of magnesium alloys and improve their corrosion resistance and mechanical properties, has the core requirement of achieving uniform cooling of the molten metal and efficient collection of solidification products, while ensuring the stability and convenience of long-term equipment operation.

[0003] Chinese patent application CN218425549U discloses a high-temperature alloy directional solidification device, relating to the field of alloy casting, which improves the problem of the short service life of current high-temperature alloy directional solidification devices. It includes an insulating sleeve, with a fixed plate fixedly connected to the outer side of the sleeve. Four sets of supporting columns are evenly fixedly connected to the bottom of the fixed plate. This application, through the arrangement of traction steel wire, winches, and heat-insulating circular plates, allows two sets of winches to be activated when the high-temperature alloy molten metal inside the crucible needs to be cooled downwards. When the winches start working, they release the wound traction steel wire, which then moves downwards under the gravity of the heat-insulating circular plate and the crucible. This causes the heat-insulating circular plate and the crucible to gradually detach from the interior of the insulating sleeve and gradually extend into the cooling chamber for cooling. Compared to using a pull-out device that penetrates the cooling chamber to move the crucible up and down, this effectively improves the sealing effect of the cooling chamber and reduces the probability of cooling medium leakage.

[0004] Although this patent optimizes the sealing performance of the cooling space by setting up a traction structure, hoisting equipment and heat insulation components, effectively reducing the probability of cooling medium leakage and solving the problem of short service life caused by poor sealing in traditional devices to a certain extent, such devices still have significant technical defects. On the one hand, they lack a targeted melt flow guiding and uniform distribution structure, which cannot achieve uniform diffusion of magnesium alloy melt on the cooling surface. The melt is prone to local accumulation or uneven flow speed, which will directly lead to large fluctuations in cooling rate and unbalanced temperature field distribution during solidification. This will result in coarse solidification structure, compositional segregation, and even local defects such as shrinkage cavities and cracks in the magnesium alloy, seriously affecting the uniformity of the final product's structure and performance consistency, making it difficult to meet the high precision requirements of high-end manufacturing for magnesium alloy materials. On the other hand, existing technologies mostly use fixed-structure scrapers to achieve the unloading of solidified magnesium alloys. The angle and scraping trajectory of such scrapers cannot be flexibly adjusted, and the residence time of magnesium alloy on the cooling roller surface cannot be adjusted according to production needs.

[0005] To address these issues, we provide a rapid solidification control device for magnesium alloys. Utility Model Content

[0006] The purpose of this invention is to provide a magnesium alloy rapid solidification control device. By combining the cooling component and the scraping component, it solves the problems of easy accumulation of molten metal and inability to adjust the scraper in the existing magnesium alloy rapid solidification control device.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a rapid solidification control device for magnesium alloys, comprising a housing, an inner cavity of which is equipped with a cooling assembly, a scraping assembly at the bottom of the cooling assembly, and a flow equalization block. Both sides of the flow equalization block are fixedly connected to the housing. A flow guide groove is formed on the surface of the flow equalization block, extending to the bottom of the block. A flow guide pipe is fixedly connected to the bottom of the flow equalization block, and a cooling roller is located at the bottom of the flow guide pipe. One side of the cooling roller is rotatably connected to the housing, and a cooling tube is detachably connected to the inner cavity of the cooling roller. An electrical outlet is located on one side of the housing. The motor output end penetrates through the surface of the housing and is fixedly connected to the cooling roller. There are four drainage pipes, with straight pipes on both sides to allow the molten liquid to fall directly onto both sides of the cooling roller surface, while the front and rear drainage pipes are bent pipes. By bending, the four drainage pipes are on the same horizontal line, allowing the molten liquid to be cooled at different positions on the same side of the cooling roller. This ensures that the molten liquid output from all drainage pipes falls at the same height and contacts the cooling roller at the same time, allowing the molten liquid to obtain consistent initial cooling conditions on the surface of the cooling roller, further improving the overall cooling uniformity of the magnesium alloy strip.

[0009] The present invention is further configured such that the scraping assembly includes a worm gear, one side of which is rotatably connected to the housing, and a worm wheel meshing with the bottom of the worm gear. One side of the worm wheel is rotatably connected to the housing, and a scraper is fixedly connected to the bottom of the other side of the worm wheel. The scraper is located at the bottom of the cooling roller, and the other side of the scraper is rotatably connected to the housing. The self-locking property of the worm wheel and the worm gear can effectively prevent the scraper from rotating in the opposite direction due to the reaction force it receives when scraping the magnesium alloy, thus avoiding accidental displacement of the scraper position.

[0010] The present invention is further configured such that a door is hinged to the front side of the box body, and a handle is fixedly connected to the surface of the door, allowing staff to quickly inspect or replace the internal components of the box body through the door.

[0011] The present invention is further configured such that the number of the flow guide channels is four, and they are arrayed on the surface of the flow equalization block. The four arrayed flow guide channels can evenly divide the magnesium alloy melt entering the flow equalization block into four streams, ensuring that the flow rate and velocity of each melt stream remain consistent.

[0012] The present invention is further configured such that a limiting groove is provided on one side of the box body, and the inner cavity of the limiting groove is slidably connected to the scraper. The limiting groove can restrict the running mode of the scraper and improve its stability when rotating.

[0013] The present invention is further provided that the inner cavity of the box is provided with a knob, one side of which is fixedly connected to the worm gear. The knob can increase the contact area with the hand compared to the worm gear, so that the operator can turn the worm gear more easily.

[0014] The present invention is further provided with a collection box at the bottom of the cooling roller, and both sides of the collection box are slidably connected to the box body. The collection box can collect the magnesium alloy falling on the cooling roller in a concentrated manner.

[0015] The present invention is further configured such that sliding grooves are provided on both sides of the inner cavity of the box, and a slider is slidably connected to the inner cavity of the sliding groove. The other side of the slider is fixedly connected to the collection box. The arrangement of the sliding groove and the slider allows the collection box to be completely pulled out from the inner cavity of the box, so that the staff can process the cooled magnesium alloy.

[0016] The present invention has the following beneficial effects.

[0017] 1. The cooling assembly of this utility model can divert and guide the incoming magnesium alloy molten metal through the flow guide groove on the surface of the flow equalization block, and achieve precise delivery of the molten metal in conjunction with the bottom guide pipe. This ensures that the molten metal is evenly and stably covered on the surface of the cooling roller, effectively avoiding the problem of local accumulation or uneven flow of the molten metal, laying the foundation for subsequent uniform solidification. The motor drives the cooling roller to rotate at a uniform speed, so that the molten metal quickly forms a thin strip on the roller surface and fully contacts the cooling surface. At the same time, the cooling pipe in the inner cavity of the cooling roller can efficiently conduct cold energy, achieving rapid and uniform cooling of the molten metal. This significantly optimizes the temperature field distribution during the solidification process, reduces cooling rate fluctuations, and is conducive to refining the solidification structure of the magnesium alloy and reducing the probability of the occurrence of local defects.

[0018] 2. The scraping assembly of this utility model uses a worm gear and worm wheel meshing transmission structure. By rotating the worm gear, the worm wheel can be driven to precisely adjust the position of the scraper. This allows for free adjustment of the residence time of the magnesium alloy strip on the cooling roller surface. The optimal cooling time can be precisely matched according to production needs, which avoids structural defects caused by insufficient cooling and prevents performance fluctuations caused by over-cooling. This significantly improves the cooling consistency and performance stability of different batches of products. Attached Figure Description

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-5 This utility model is a magnesium alloy rapid solidification control device, including a box body 1, a cooling component 2 is provided in the inner cavity of the box body 1, a scraping component 3 is provided at the bottom of the cooling component 2, the cooling component 2 includes a flow equalization block 201, both sides of the flow equalization block 201 are fixedly connected to the box body 1, a flow guide groove 202 is opened on the surface of the flow equalization block 201, the flow guide groove 202 extends to the bottom of the flow equalization block 201, a flow guide pipe 203 is fixedly connected to the bottom of the flow equalization block 201, a cooling roller 204 is provided at the bottom of the flow guide pipe 203, one side of the cooling roller 204 is rotatably connected to the box body 1, a cooling pipe 205 is detachably connected to the inner cavity of the cooling roller 204, a motor 206 is provided on one side of the box body 1, the output end of the motor 206 passes through the surface of the box body 1 and is fixedly connected to the cooling roller 204.

[0028] Specifically, there are four guide tubes 203. The two sides are straight tubes, allowing the molten liquid to fall directly onto the sides of the cooling roller 204. The front and rear guide tubes 203 are bent tubes. By bending, the four guide tubes 203 are on the same horizontal line, so that the molten liquid can be cooled at different positions on the same side of the cooling roller 204. This ensures that the molten liquid output from all guide tubes 203 falls at the same height and contacts the cooling roller 204 at the same time, so that the molten liquid obtains consistent initial cooling conditions on the surface of the cooling roller 204, further improving the overall cooling uniformity of the magnesium alloy strip.

[0029] Please see Figure 1-5 The scraping assembly 3 includes a worm gear 301, one side of which is rotatably connected to the housing 1. A worm wheel 302 meshes with the bottom of the worm gear 301, one side of which is rotatably connected to the housing 1. A scraper 303 is fixedly connected to the bottom of the other side of the worm wheel 302. The scraper 303 is located at the bottom of the cooling roller 204, and the other side of the scraper 303 is rotatably connected to the housing 1. A door 4 is hinged to the front of the housing 1, and a handle 5 is fixedly connected to the surface of the door 4. The number of guide channels 202 is four. Each cooling roller 204 has a collection box 8 at its bottom. The collection box 1 has a limit groove 6 on one side, and the inner cavity of the limit groove 6 is slidably connected to the scraper 303. The inner cavity of the collection box 1 is provided with a knob 7, and one side of the knob 7 is fixedly connected to the worm gear 301. The collection box 8 is slidably connected to the collection box 1 on both sides. The inner cavity of the collection box 1 has a sliding groove 9 on both sides, and a slider 10 is slidably connected to the inner cavity of the sliding groove 9. The other side of the slider 10 is fixedly connected to the collection box 8.

[0030] The self-locking property of the worm gear 302 and worm 301 can effectively prevent the scraper 303 from rotating in the opposite direction due to the reaction force when scraping magnesium alloy, thus avoiding accidental displacement of the scraper 303. The staff can quickly inspect or replace the internal components of the box 1 through the box door 4. The four arrayed guide channels 202 can evenly divide the magnesium alloy melt entering the flow equalization block 201 into four streams, ensuring that the flow rate and velocity of each stream of melt are consistent. The limiting groove 6 can restrict the operation mode of the scraper 303 and improve its stability when rotating. The knob 7 has a larger contact area with the hand compared to the worm 301, making it easier for the staff to turn the worm 301. The collection box 8 can collect the magnesium alloy that falls on the cooling roller 204. The slide 9 and slider 10 can completely pull the collection box 8 out of the inner cavity of the box 1, so that the staff can process the cooled magnesium alloy.

[0031] The working principle of this utility model is as follows: Before use, the position of the scraper 303 is adjusted according to the different specifications of magnesium alloy. By rotating the knob 7, the knob 7 drives the worm 301 to rotate, the worm 301 drives the worm wheel 302 to rotate, and the worm wheel 302 drives the scraper 303 to rotate, thereby realizing the adjustment of the position of the scraper 303. When in use, the molten liquid is poured into the top of the flow equalization block 201. The flow equalization block 201 divides the molten liquid into four parts evenly through the flow guide groove 202, and then the liquid is evenly distributed on different positions on the surface of the cooling roller 204 through the flow guide pipe 203. The motor 206 rotates to drive the cooling roller 204 to rotate. The cooling roller 204 cools the molten liquid through the internal cooling pipe 205. The cooling pipe 205 is connected to an external cooling circulation device to achieve continuous operation. When the molten liquid comes into contact with the cooling roller 204, it is instantly cooled and solidified and adhered to the cooling roller 204. Finally, it is scraped off from the cooling roller 204 by the scraper 303.
