Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal processing technology, specifically a rolling device for high thermal conductivity metal processing. Background Technology
[0002] High thermal conductivity metals refer to metallic materials with excellent thermal conductivity, which are widely used in heat dissipation devices and applications requiring efficient heat transfer.
[0003] In the processing of high thermal conductivity metals, they need to be rolled multiple times to gradually roll the billet or thick plate to the target thickness. Traditional rolling equipment includes a rolling mill system, a transmission system and a coiler. The rolling mill is driven by a motor, and the rolling mill applies pressure to the metal to cause plastic deformation, thereby obtaining the required shape and size.
[0004] During the rolling process, as the degree of deformation increases, the strength and hardness of metallic materials also increase, resulting in work hardening. This can easily lead to a decrease in the plasticity of the material, making it difficult to achieve uniform plastic deformation during the rolling process, thus causing dimensional deviations.
[0005] Therefore, this utility model provides a rolling device for high thermal conductivity metal processing. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A high thermal conductivity metal processing rolling device according to this utility model includes a rolling mill, two conveying rollers installed in the middle of the rolling mill, two rolling rollers installed in the middle of the rolling mill, a preheating box fixedly connected to the middle of the rolling mill, two preheating grooves opened in the middle of the preheating box, the two preheating grooves being arranged opposite each other, two fixing boxes fixedly connected to the middle of the preheating box, the two fixing boxes being fixedly connected to the corresponding preheating groove positions, two through grooves opened on the sidewalls of the fixing boxes, the two through grooves being arranged opposite each other, and multiple through grooves opened in the middle of the fixing boxes. The structure includes a hole, two fans installed in the middle of the fixing box, and two mesh plates installed on the inner wall of the preheating box. The two mesh plates are positioned near the preheating tank, and heating wires are installed in the middle of the mesh plates, with the heating wires positioned near the fans. This structure effectively preheats the metal material before rolling, reducing the temperature gradient of the metal material during the rolling process. This makes the metal product easier to plastically deform, reduces dimensional deviations caused by uneven local hardness, and thus improves the precision and quality of the metal product. It also effectively increases the fluidity of the metal during the rolling process, making it easier to form the required shape and structure.
[0008] Preferably, an oil storage tank is fixedly connected to the outer wall of the preheating box, an oil inlet pipe is fixedly connected to the top of the oil storage tank, a pump body is installed on the top of the oil storage tank, a connecting pipe is fixedly connected to the middle of the pump body, the end of the connecting pipe is fixedly connected to the top of the oil storage tank, an oil outlet pipe is fixedly connected to the middle of the pump body, an oil drain pipe is fixedly connected to the end of the oil outlet pipe, the oil drain pipe is fixedly connected to the side wall of the preheating box, the oil drain pipe is located at the corresponding through groove position, and two sets of spray heads are fixedly connected to the middle of the oil drain pipe. The two sets of spray heads are located on both sides of the through groove. Through the above structure, the lubricating oil can effectively reduce the direct contact between the metal material and the calendering roller, reduce the friction between the metal and the calendering roller, reduce the scratches or surface defects caused by frictional resistance of the metal material during the calendering process, and improve the smoothness and dimensional accuracy of the metal product.

The two fixed rods are located on the side away from the oil drain pipe and are fixed to both sides of the through groove. The fixed rods have an installation groove in the middle, and an installation rod is installed in the middle of the installation groove. A scraper is fixed to the middle of the installation rod, and the two scrapers are arranged opposite each other. This structure can effectively remove dust and impurities from the surface of the metal material to be rolled, making the surface of the cleaned metal material smoother. This effectively reduces the frictional resistance caused by dust and impurities during the rolling process and reduces wear between the metal material and the rolling roller.
[0010] Preferably, two sets of connecting rods are fixedly connected to the middle of the through groove, and the ends of the two opposing connecting rods are rotatably connected to rollers. The rolling of the rollers in the above structure can effectively reduce the direct friction between the metal material and the preheating box, thereby reducing frictional resistance and reducing the wear of the metal material.
[0011] Preferably, a rubber pad is installed in the middle of the roller and is fixed to the outer wall of the roller. Through the above structure, the soft material of the rubber pad can closely adhere to the surface of the metal material, forming a buffer layer between the roller and the metal material, which can reduce the wear on the roller surface and make the metal material more stable when moving on the roller.
[0012] Preferably, a filter screen is provided in the middle of the through hole, and the filter screen is fixed in the middle of the through hole. The above structure can effectively reduce the entry of impurities and dust in the air into the fixed box and directly contact the fan, thereby reducing the accumulation of impurities on the fan surface and causing wear.

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 4As shown in the figure, a high thermal conductivity metal processing rolling device according to an embodiment of the present invention includes a rolling mill 1, two conveying rollers 10 and two rolling rollers 11 installed in the middle of the rolling mill 1, a preheating box 12 fixedly connected to the middle of the rolling mill 1, two preheating grooves 13 opened in the middle of the preheating box 12, the two preheating grooves 13 being arranged opposite each other, and two fixing boxes 14 fixedly connected to the middle of the preheating box 12, the two fixing boxes 14 being fixedly connected to the corresponding positions of the preheating grooves 13, and the side walls of the fixing boxes 14 being... Two through slots 15 are provided, which are arranged opposite each other. Multiple through holes 16 are opened in the middle of the fixing box 14. Two fans 17 are installed in the middle of the fixing box 14. Two mesh plates 19 are installed on the inner wall of the preheating box 12, located near the preheating slot 13. Heating wires 18 are installed in the middle of the mesh plates 19, located near the fans 17. During operation, the heat-conducting metal, during the rolling process, first passes through the middle of the preheating box 12, and then flows from the middle of the two through slots 15. The metal is conveyed by two conveying rollers 10. When the metal passes through the middle of the two rolling rollers 11, the rolling rollers 11 roll the metal. When the metal passes through the inside of the through groove 15, the two fans 17 and the heating wire 18 are turned on, causing the fan blades in the fan 17 to rotate at high speed. The fan 17 draws in external airflow and blows it into the preheating box 12, controlling the heat emitted from the surface of the heating wire 18. The airflow heats up after passing through the heating wire 18, forming a heat flow. When the metal material passes through the preheating box 12, the heat flow blows onto the surface of the metal material, thereby preheating the metal material. The above structure can effectively preheat the metal material before rolling, reduce the temperature gradient of the metal material during the rolling process, and make the metal product easier to plastically deform, reduce the dimensional deviation caused by uneven local hardness, thereby improving the precision and quality of the metal product. It can also effectively increase the fluidity of the metal during the rolling process, making it easier to form the required shape and structure.
[0024] like Figure 1 and Figure 2As shown, an oil reservoir 2 is fixedly connected to the outer wall of the preheating box 12. An oil inlet pipe 21 is fixedly connected to the top of the oil reservoir 2. A pump body 22 is installed on the top of the oil reservoir 2. A connecting pipe 23 is fixedly connected to the middle of the pump body 22. The end of the connecting pipe 23 is fixedly connected to the top of the oil reservoir 2. An oil outlet pipe 24 is fixedly connected to the middle of the pump body 22. An oil drain pipe 25 is fixedly connected to the end of the oil outlet pipe 24. The oil drain pipe 25 is fixedly connected to the side wall of the preheating box 12 and is located at the corresponding position of the through groove 15. Two sets of spray nozzles 26 are fixedly connected to the middle of the oil drain pipe 25. The two sets of spray nozzles 26 are located on both sides of the through groove 15. During operation, the lubricating oil is pumped through the oil inlet pipe. 21 is injected into the oil storage tank 2 for storage. During the metal material stretching process, the control pump 22 is turned on, and the pump 22 draws the lubricating oil from the connecting pipe 23. The lubricating oil enters the drain pipe 25 through the oil outlet pipe 24, and then the lubricating oil is sprayed onto the surface of the metal material through multiple spray nozzles 26 to form an oil mist. Through the above structure, the lubricating oil can effectively reduce the direct contact between the metal material and the stretching roller 11, reduce the friction between the metal and the stretching roller 11, reduce the scratches or surface defects caused by frictional resistance in the metal material during the stretching process, and improve the smoothness and dimensional accuracy of the metal product.
[0025] like Figure 2 and Figure 4 As shown, two fixing rods 3 are fixed to the side wall of the preheating box 12. The two fixing rods 3 are located on the side away from the oil drain pipe 25 and are fixed to both sides of the through groove 15. An installation groove 31 is opened in the middle of the fixing rod 3, and an installation rod 32 is installed in the middle of the installation groove 31. A scraper 33 is fixed to the middle of the installation rod 32. The two scrapers 33 are arranged opposite each other. During operation, one end of the scraper 33 is aligned with the end of the fixing rod 3, so that the installation rod 32 is aligned with the position of the installation groove 31. The installation rod 32 is slid into the inside of the fixing rod 3, and the scraper 33 is fixed by the fixing rod 3. When the metal material enters the preheating box 12, the two scrapers 33 come into contact with both sides of the metal material. The scrapers 33 clean the surface of the metal material. The above structure can effectively remove dust and impurities from the surface of the metal material to be rolled, making the surface of the cleaned metal material smoother. This effectively reduces the frictional resistance caused by dust and impurities during the rolling process and reduces the wear between the metal material and the rolling roller 11.
[0026] like Figure 3 and Figure 4 As shown, two sets of connecting rods 4 are fixedly connected to the middle of the through groove 15. The ends of the two opposing connecting rods 4 are rotatably connected to rollers 41. During operation, when the metal material passes through the inside of the preheating box 12, it comes into contact with the metal material through the rollers 41. As the metal material is conveyed, the rollers 41 rotate at both ends of the connecting rods 4. Through the rolling of the rollers 41 in the above structure, the direct friction between the metal material and the preheating box 12 can be effectively reduced, thereby reducing frictional resistance and reducing wear of the metal material.
[0027] like Figure 4 As shown, a rubber pad 5 is installed in the middle of the roller 41. The rubber pad 5 is fixed to the outer wall of the roller 41. During operation, when the metal material moves through the middle of the preheating box 12, it comes into contact with the metal material through the rubber pad 5 in the middle of the roller 41, increasing the friction between the roller 41 and the metal material. Through the above structure, the soft material of the rubber pad 5 can closely adhere to the surface of the metal material, forming a buffer layer between the roller 41 and the metal material, which can reduce the wear on the surface of the roller 41 and make the metal material move more stably on the roller 41.
[0028] like Figure 3 As shown, a filter screen 6 is provided in the middle of the through hole 16. The filter screen 6 is fixed in the middle of the through hole 16. When working, when the external airflow enters the fixed box 14 through the fan 17, the airflow first passes through the through hole 16 and is intercepted by the filter screen 6. The above structure can effectively reduce the amount of impurities and dust in the air entering the fixed box 14 and directly contacting the fan 17, and reduce the accumulation of impurities on the surface of the fan 17 and the resulting wear.
[0029] like Figure 2 As shown, a transparent plate 7 is provided on the side wall of the oil reservoir 2. The transparent plate 7 is located on one side of the oil reservoir 2. During operation, the lubricating oil usage inside the oil reservoir 2 can be directly observed through the transparent plate 7. The above structure allows for quick observation of the lubricating oil storage level inside the oil reservoir 2. When the lubricating oil inside the oil reservoir 2 is about to run out, it can be added in time to reduce lubrication interruption.
[0030] During operation, the heat-conducting metal first passes through the middle of the preheating box 12 and through the middle of the two through slots 15 during the rolling process. The metal is positioned and conveyed by two conveying rollers 10. When the metal passes through the middle of the two rolling rollers 11, the metal is rolled by the two rolling rollers 11. When the metal passes through the inside of the through slot 15, the two fans 17 and heating wires 18 are turned on, causing the fan blades in the fans 17 to rotate at high speed. The fans 17 draw in external airflow and blow it into the preheating box 12, controlling the heat emitted from the surface of the heating wires 18. The airflow heats up after passing through the heating wires 18, forming a heat flow. When the metal material passes through the preheating box 12, the heat flow blows onto the surface of the metal material, thereby preheating the metal material. The lubricating oil is injected into the oil storage tank 2 through the oil inlet pipe 21 for storage. During the metal material rolling process, the pump body 22 is turned on, and the lubricating oil is drawn out from the connecting pipe 23 through the pump body 22. The lubricating oil enters the oil discharge pipe 25 through the oil outlet pipe 24, and then passes through multiple spray nozzles. The mist nozzle 26 sprays lubricating oil into a mist onto the surface of the metal material. One end of the scraper 33 is aligned with the end of the fixing rod 3, and the mounting rod 32 is aligned with the mounting groove 31. The mounting rod 32 is slid into the fixing rod 3, and the scraper 33 is fixed by the fixing rod 3. When the metal material enters the preheating box 12, the two scrapers 33 contact both sides of the metal material, and the scraper 33 cleans the surface of the metal material. When the metal material passes through the preheating box 12, it comes into contact with the roller 41. As the metal material conveying roller 41 rotates at both ends of the connecting rod 4, the metal material moves through the middle of the preheating box 12. The rubber pad 5 in the middle of the roller 41 adheres to the metal material, increasing the friction between the roller 41 and the metal material. When the external airflow enters the fixed box 14 through the fan 17, the airflow first passes through the through hole 16 and is intercepted by the filter screen 6. During the use of lubricating oil, the lubricating oil usage in the oil storage tank 2 can be directly observed through the transparent plate 7.
