[0002] Copper-aluminum alloy wire drawing process refers to the process of making alloy wire by mixing copper and aluminum in a certain proportion and then processing it into a fine wire of the required diameter through a series of processing steps. This process is widely used in the fields of wires and cables, electrical equipment, etc., because it combines the excellent conductivity of copper and the lightweight properties of aluminum, and has good comprehensive performance.

[0003] Traditional copper-aluminum alloy wire drawing processes typically involve multiple steps, including heating, drawing, and cleaning. However, in actual production, copper-aluminum alloy wires are prone to oxidation at high temperatures and breakage due to excessive friction during drawing. Therefore, lubrication is usually required. However, existing drawing equipment lacks automated lubrication systems, typically requiring manual application of lubricating oil to the wires. This not only increases operational complexity and labor intensity but also causes manually applied lubricating oil to drip onto the equipment or floor, resulting in environmental pollution.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-4A copper-aluminum alloy wire drawing device includes a worktable 1, a wire drawing mechanism, and a lubrication mechanism. The wire drawing mechanism is mounted on the worktable 1 and includes a first motor 6, a connecting shaft 7, a transmission shaft 70, a first bevel gear 8, a second bevel gear 9, a conveyor wheel 10, a wire drawing die 13, a cleaning assembly 14, a second motor 15, a take-up wheel 16, a heater 17, and a heating plate 18. The worktable 1 has two symmetrically distributed first motors 6 mounted on its rear side. Each of the two first motors 6 has a connecting shaft 7 connected to its output shaft. Two first bevel gears 8 are mounted on the connecting shaft 7. Two sets of transmission shafts 70 are symmetrically distributed on the worktable 1, corresponding to the positions of the first bevel gears 8. Each set of transmission shafts 70... A second bevel gear 9 is provided at one end of the drive shaft 70 near the first bevel gear 8. The second bevel gear 9 meshes with the corresponding first bevel gear 8 for transmission. A conveyor wheel 10 for conveying copper-aluminum alloy wire is installed at the other end of the drive shaft 70. A wire drawing mold 13 is provided on the workbench 1 between the two sets of conveyor wheels 10. The wire drawing mold 13 can be disassembled and replaced as needed. A cleaning component 14 is provided on the workbench 1 to the right of the two sets of conveyor wheels 10 for wiping off oxides and impurities on the copper-aluminum alloy wire. A second motor 15 is provided to the right of the cleaning component 14. A winding wheel 16 for winding the copper-aluminum alloy wire is provided on the output shaft of the second motor 15. The workbench 1 is provided with a winding wheel 16 for winding the copper-aluminum alloy wire. A heater 17 is located to the left of the conveyor wheel 10. The heater 17 is equipped with a heating plate 18 for softening the copper-aluminum alloy wire. A lubrication mechanism is located behind the workbench 1. The lubrication mechanism includes a collection tank 2, a first pump 3, a guide pipe 4, a suction shell 5, a second pump 11, a double-ended guide pipe 12, a filter screen 27, and a protective shell 28. A collection trough is located on the left side of the workbench 1, below the conveyor wheel 10 and the wire drawing mold 13. This trough collects lubricating oil dripping from the copper-aluminum alloy wire. The bottom surface of the collection trough is sloped to facilitate the discharge of the collected lubricating oil to the left. A collection tank 2, containing lubricating oil, is located behind the workbench 1. A transparent glass panel is embedded in the rear of the collection tank 2. 29. The transparent glass 29 allows operators to directly observe the interior of the collection tank, including the lubricating oil level and its condition. A first pump 3 and a second pump 11 are installed on the top of the collection tank 2. The outlet of the first pump 3 is connected to the collection tank 2 to draw lubricating oil collected in the collection tank, while the inlet is connected to a guide pipe 4. A suction shell 5 is located near the collection tank at one end of the guide pipe 4, inside the drain outlet on the left side of the collection tank, to collect lubricating oil. When the first pump 3 starts, the lubricating oil collected in the collection tank is drawn back to the collection tank 2 through the guide pipe 4. A filter screen 27 is installed inside the suction shell 5 to filter impurities and particles from the lubricating oil.To prevent these impurities from re-entering the lubrication system, the inlet of the second pump 11 is connected to the collection tank 2 to extract the lubricating oil. The outlet is connected to a double-ended guide pipe 12, whose two ends guide the lubricating oil to two sets of conveyor rollers 10. The conveyor rollers 10 evenly coat the copper-aluminum alloy wire with lubricating oil, ensuring effective lubrication. A protective shell 28 is installed on top of the collection tank 2, and the first pump 3 is located inside the protective shell 28, protecting it from external environmental influences.

[0025] First, one end of the produced copper-aluminum alloy wire is wound onto a take-up reel 16 driven by a second motor 15. The take-up reel 16 pulls the copper-aluminum alloy wire as it winds. During this movement, the wire first passes through a heater 17, where a heating plate 18 preheats it, making it easier to stretch and reducing the risk of breakage during the stretching process. Next, it moves to the lubrication and drawing area. A second liquid pump 11 starts, delivering lubricating oil from the collection tank 2 through a double-ended guide pipe 12 to the two sets of conveyor wheels 10. This ensures the lubricating oil is evenly distributed on the copper-aluminum alloy wire, reducing friction between the wire and the equipment and improving drawing efficiency. Meanwhile, the lubricating oil dripping during the lubrication process... The lubricating oil is collected in the collection tank and then pumped back to the collection tank 2 by the first pump 3 and the guide pipe 4, realizing the recycling of the lubricating oil. Then, as the first motor 6 drives the connecting shaft 7 to rotate, the first bevel gear 8 and the second bevel gear 9 mesh to drive the transmission shaft 70 and the conveying wheel 10 to rotate, thereby assisting the movement of the copper-aluminum alloy wire. The copper-aluminum alloy wire passes through the drawing die 13 and is drawn into a thin wire of the required diameter under the action of tension. After the wire is drawn, the copper-aluminum alloy wire passes through the cleaning component 14 to remove any oxides and impurities that may be generated on the surface to ensure the quality of the product. The cleaned copper-aluminum alloy wire is then wound up by the winding wheel 16 to form the final product.

[0026] Example 2: Based on Example 1, please refer to... Figure 4 and Figure 5 It also includes a cooling assembly, which is disposed between the conveyor wheel 10 and the cleaning assembly 14. The cooling assembly includes a housing 19, a cooling pipe 20, and a cooler 21. The housing 19 is fixed on the workbench 1 and located between the conveyor wheel 10 and the cleaning assembly 14. The cooler 21 is disposed at the lower part of the housing 19 and is responsible for providing cooling. The cooling pipe 20 is disposed around the inside of the housing 19 and is used to cool the copper-aluminum alloy wire. The surrounding design ensures that the copper-aluminum alloy wire can be cooled down quickly when passing through the cooling assembly.

[0027] When the copper-aluminum alloy wire emerges from the drawing die and passes through the housing 19 of the cooling assembly, the cooling medium in the cooling pipe 20 comes into contact with the copper-aluminum alloy wire, carrying away heat. The heat exchange between the cooling medium and the copper-aluminum alloy wire causes the copper-aluminum alloy wire to cool down rapidly, achieving the required cooling effect, thereby maintaining the good physical properties of the wire. This ensures that the copper-aluminum alloy wire is cooled immediately after drawing, avoiding the impact of high temperature on subsequent cleaning and winding steps.

[0028] Please see Figure 6 The system also includes a measuring component, which is positioned between the cooling component and the cleaning component 14. This component includes a support base 22, a measuring ruler 220, a measuring plate 23, a display screen 24, an alarm 25, and a controller 26. The support base 22 is fixed to the workbench 1 and located between the cooling component and the cleaning component 14. The measuring ruler 220 and the display screen 24 are both mounted on the top of the support base 22. The measuring plate 23 is slidably mounted on the measuring ruler 220. The measuring plate 23, in conjunction with the measuring ruler 220, can measure the dimensions of the drawn copper-aluminum alloy wire. The alarm 25 and the controller 26 are mounted on the front side of the support base 22, serving as an alarm and control unit, respectively. When a dimension is found to be non-compliant, the alarm 25 will emit a sound or light signal to alert the operator, while the controller 26 will trigger the relevant equipment to stop or adjust operating parameters to ensure product quality.

[0029] After passing through the cooling assembly, the copper-aluminum alloy wire reaches the measuring assembly. The measuring plate 23 contacts the copper-aluminum alloy wire and detects its actual size using its built-in sensor. The measurement result is transmitted to the controller 26 via a signal and displayed on the screen 24. At the same time, the controller 26 receives the signal from the measuring plate 23 and compares it with the preset standard size. If the detected size does not conform to the set standard range, the controller 26 will trigger the alarm 25 to issue an alarm. In addition, the controller 26 can further link other equipment on the production line, such as temporarily stopping the production line, adjusting the speed or pressure of the wire drawing machine, etc., to correct the size deviation.

[0030] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
