Description

Technical Field

[0001] The invention belongs to the technical field of zinc alloy rolling processing, and in particular relates to a zinc alloy rolling continuous material forming device. Background Art

[0002] In the field of metal processing, zinc alloys have become a key material in electronic components, architectural decoration, automotive parts, and hardware products due to their excellent physical properties, good casting characteristics, and recyclability. As industrial manufacturing evolves towards precision and efficiency, traditional intermittent rolling processes have gradually exposed technical bottlenecks such as low production efficiency, high energy consumption, and large fluctuations in yield rates, seriously restricting the large-scale application of zinc alloy materials in high-end manufacturing.

[0003] There are two typical defects in the existing zinc alloy rolling technology: the first is the use of a preheating-intermittent rolling process, which requires the zinc alloy to be heated to the process temperature for the second time before rolling, resulting in a significant increase in energy consumption. The intermittent production mode restricts the increase in production capacity and is difficult to meet the needs of large-scale production; the second is the direct transportation of molten zinc alloy for continuous rolling. Although the closed pipeline transportation avoids external environmental pollution, the molten metal will still undergo an oxidation reaction when it comes into contact with residual air. At the same time, metal residue is easily formed on the inner wall of the pipeline, which not only affects the product purity but also increases the equipment maintenance cost.

[0004] The above technical defects form a dual constraint: the preheating process leads to interruption of production continuity and energy waste, while direct calendering in the molten state causes material oxidation and equipment cleaning problems. Summary of the Invention

[0030] Example 1 See also Figures 1-6 A zinc alloy continuous rolling device includes a zinc alloy melt tank 12 and a rolling device body 13. The zinc alloy melt tank 12 is used to temporarily store the molten zinc alloy melt and can also be a smelting furnace to facilitate the transportation of the zinc alloy after smelting. The rolling device body 13 mainly includes: The roller system can be arranged in four or five rollers according to the needs, and can be arranged in an oblique Z or L shape. The rollers are made of chilled cast iron or alloy steel, which has high wear resistance and thermal conductivity. The rollers are designed with a drilled structure inside, and heat transfer oil or water is circulated through the oblique holes to ensure uniform heat exchange, which is suitable for the hot rolling requirements of zinc alloys. The temperature control system is specifically divided into a heating system and a cooling system. The heating system uses an oil temperature machine or electric heating, with high temperature control accuracy. The zinc alloy rolling temperature is usually set at 100-250°C. The cooling system is designed to be air-cooled or water-cooled, which can quickly shape the zinc plate and prevent grain coarsening. The drive device can be composed of an electric motor, a gear reducer, a universal coupling, etc., and supports independent speed regulation of multiple rollers with a speed ratio range of 1:1.1~1:1.5. It refines alloy grains through differentiated shear force and can also be equipped with a variable frequency speed regulation system to meet the dynamic processing requirements of zinc plates of different thicknesses. Mounting frames 11 are symmetrically provided at both ends of the rolling device body 13 to ensure overall stability. A conveying mechanism is provided between the zinc alloy molten tank 12 and the rolling device body 13. A guide roller 14 is provided at one end of the mounting frame 11 away from the conveying mechanism, which can facilitate the conveying and guiding of the zinc alloy after it is rolled into a material, facilitate subsequent winding and other operations, and facilitate subsequent processing operations. In order to facilitate the transportation of the zinc alloy melt and realize continuous processing while avoiding oxidation, etc., without affecting the rolling process, the conveying mechanism includes a liquid outlet pipe 16 arranged on the side wall of the zinc alloy molten tank 12. The end of the liquid outlet pipe 16 is inclinedly provided with a conveying pipe 15. For the conveying pipe 15, the inclination angle can be 4-10°, which assists the flow of the zinc alloy melt and avoids excessive flow rate, thereby ensuring the processing speed of the rolling device body 13 and continuous production. It can also be other inclination angles according to the situation. The inner layer of the delivery pipe 15 can be made of high-temperature resistant refractory materials that are insoluble in zinc alloys, such as coke aggregate + high-aluminum powder, to prevent impurities such as iron and nickel from contaminating the melt. The lower end of the delivery pipe 15 matches the feed port of the rolling device body 13. A guide plate 17 is provided on one side of the lower end of the delivery pipe 15. The guide plate 17 matches the feed port of the rolling device body 13. The delivery pipe 15 is used for zinc alloy melt. The flow direction of the zinc alloy melt is from the zinc alloy melt tank 12 to the rolling device body 13. Fixed blocks 61 are equidistantly provided at both ends of the delivery pipe 15, and a support leg 62 is vertically provided at the bottom end of the fixed block 61. A fixed support foot 63 is provided at the bottom end of the support leg 62 to ensure the overall stability of the delivery pipe 15. A heat exchange mechanism is provided on the inner wall of the delivery pipe 15, and a protective component is provided at one end of the delivery pipe 15 close to the liquid outlet pipe 16. An auxiliary mechanism is provided at the bottom end of the delivery pipe 15.

[0031] See also Figures 1-6In order to facilitate the continuous processing of the zinc alloy melt and ensure that the zinc alloy melt is at the optimal rolling temperature of 250-350℃, and to ensure that the melt is in a "semi-solid" viscous flow state with both fluidity and plasticity, the heat exchange mechanism includes heat exchange tubes 33 equidistantly arranged inside the conveying pipe 15. The inner diameter of the heat exchange tubes 33 gradually decreases along the flow direction of the zinc alloy melt, and then the amount of liquid in the heat exchange tubes 33 gradually decreases. The closer to one end of the rolling device body 13, the closer the heat exchange tubes 33 are to the zinc alloy melt. The lower the heat exchange of the melt, the more gradually it can be cooled, while avoiding the temperature being too low, ensuring that the zinc alloy melt is at the optimal rolling temperature. Both ends of the heat exchange tube 33 pass through the conveying pipe 15, one end of the heat exchange tube 33 is connected to the liquid inlet pipe 31, and the other end of the heat exchange tube 33 is connected to the liquid return pipe 32. The heat exchange tubes 33 can be arranged at intervals of 10-30 cm in the conveying pipe 15 to ensure the heat exchange effect and achieve gradient cooling. The liquid inside the heat exchange tube 33 can be water, etc., and the liquid inlet pipe 31 is connected to the liquid return pipe 32. Both the pipe 31 and the return liquid pipe 32 are connected to a liquid storage tank (not shown in the figure), which can facilitate circulation. For the liquid storage tank, a refrigeration device can be provided inside according to actual conditions to facilitate cooling of the liquid after heat exchange, so as to facilitate subsequent recycling. The temperature of the initial heat exchange liquid can be -10-5°C. It is set according to the actual heat exchange of the zinc alloy melt in the conveying pipe 15 to ensure that it is at the optimal rolling temperature when it flows to the feed port of the rolling device main body 13. The setting can be selected according to actual conditions, or other temperatures can be selected. The protection component includes a sealing plate 52 arranged on the side of the conveying pipe 15 near the liquid outlet pipe 16, and a through hole 53 matching the liquid outlet pipe 16 is opened in the middle of the sealing plate 52. A protective gas inlet pipe 51 matching the conveying pipe 15 is symmetrically provided on the sealing plate 52. For the protective gas inlet pipe 51, the protective gas introduced therein can be nitrogen or other protective gases. In order to reduce contact with oxygen in the air and avoid oxidation and other impurities that affect the quality and effect of subsequent rolling.

[0032] See also Figures 1-6 In order to facilitate regular cleaning of the inside of the conveying pipe 15 without affecting the protection effect of conveying during production, a through groove is provided on the top of the conveying pipe 15, and a cover plate 21 is provided in the through groove. The material of the cover plate 21 is the same as that of the conveying pipe 15, which can withstand high temperatures and prevent impurities such as iron and nickel from contaminating the melt. Connecting strips 23 are symmetrically provided at both ends of the cover plate 21, and a connecting groove 24 is provided in the through groove to connect with the connecting strip 23, which is convenient for installation and plugging. A handle 22 is provided on the side of the cover plate 21 close to the main body 13 of the calendering device to facilitate installation and plugging operations.

[0033] See also Figures 1-6In order to assist the flow of zinc alloy melt, avoid residue, assist the transportation of zinc alloy melt, and facilitate subsequent rolling processing, the auxiliary mechanism includes a crankshaft 41 arranged at the bottom end of the conveying pipe 15, one end of the crankshaft 41 is connected to the conveying pipe 15 through a bearing seat, and the other end of the crankshaft 41 is fixedly connected to the output end of the motor 42, and the motor 42 is connected to the conveying pipe 15 through a mounting seat 43. Rings 44 are equidistantly provided on the crankshaft 41. The number of rings 44 can be four, five or six groups. A rotating member 72 is provided in the middle of the rotating member 72, and a striking block 74 is provided at the end of the rotating member 72. A guide block 71 corresponding to the striking block 74 is provided at the bottom end of the conveying pipe 15. The number of the guide blocks 71 is the same as that of the striking blocks 74 and the collar 44, and they correspond to each other. A sliding groove 73 for the striking block 74 to slide back and forth is provided inside the guide block 71. A rubber pad 75 is provided on the end surface of the striking block 74 away from the rotating member 72. The rubber pad 75 matches the conveying pipe 15 to avoid hard contact with the conveying pipe 15 during the reciprocating vibration and striking process.

[0034] Working principle: First, the protective gas is introduced into the conveying pipe 15 through the protective gas inlet pipe 51, and then the zinc alloy melt in the zinc alloy melt tank 12 is discharged into the conveying pipe 15 through the liquid outlet pipe 16. During the flow and transportation of the zinc alloy melt, the liquid to be heat exchanged is introduced through the liquid inlet pipe 31, and is introduced into the heat exchange pipe 33 to exchange heat with the zinc alloy melt, and gradually cool down to ensure that it is at a better rolling temperature when it is transported to the rolling device body 13. The liquid after heat exchange is refluxed through the liquid return pipe 32, and circulated again after cooling to perform heat exchange. At the same time, during the transportation process, the motor 42 works, driving the crankshaft 41 By rotating, cooperating with the ring 44 and the rotating part 72, the knocking block 74 can be slid back and forth in the sliding groove 73 of the guide block 71, and the rubber pad 75 can be used to assist in knocking the bottom of the conveying pipe 15 to assist the conveying flow and avoid residue. After being transported to the calendering device body 13, the zinc alloy melt can be calendered through its work. After the processing is completed, when the inside of the conveying pipe 15 needs to be cleaned, the handle 22 can be pulled to move the connecting strips 23 at both ends of the cover plate 21 in the connecting groove 24 to remove the cover plate 21, thereby facilitating the cleaning and recycling of the inside of the conveying pipe 15 to avoid residual zinc alloy melt.
