Description

Technical Field

[0001] This utility model relates to the field of copper wire production technology, specifically a copper wire fine drawing machine. Background Technology

[0002] In the copper wire processing industry, there is an urgent need to improve equipment performance, while traditional equipment has many limitations. On the one hand, when refining the diameter of copper wire, traditional copper wire drawing machines often cause defects such as scratches and cracks on the surface of the copper wire due to die extrusion, affecting conductivity and subsequent processing. At the same time, the copper wire is prone to local thinning or breakage due to tension fluctuations during stretching, and the oxide layer and impurities on the surface of the raw materials will accelerate die wear and reduce the yield. In the traditional process, cleaning and preheating are separated in the pretreatment stage. On the other hand, traditional wire drawing machines lack functional integration, combining functions such as drawing, limiting, and cooling into a single structure, resulting in high maintenance costs and difficulty in upgrading. The cooling efficiency is also low because the heat cannot be dissipated in time during high-speed stretching, which easily causes the copper wire to soften and break. In addition, they rely on manual monitoring of tension and die replacement, resulting in low automation, low efficiency, and a high risk of error. In addition, the industry has high requirements for equipment reliability and adaptability, but the differences in hardness and diameter of copper rods from different batches will cause traditional equipment to be frequently shut down for adjustment. Changing the mold of traditional equipment requires disassembling the entire drawing unit, which is time-consuming and easily damages parts. In continuous operation, the diameter deviation is also prone to accumulate due to mold wear. For the above problems, there may already be technical means to solve them in the prior art, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0009] Beneficial effects

[0010] This utility model provides a copper wire drawing machine. Compared with existing technologies, this copper wire drawing machine offers the following advantages: A pretreatment system integrating a cleaning brush, air blowing device, and electric heating rod efficiently removes the oxide layer and impurities from the copper wire surface and completes preheating, providing high-quality raw materials for subsequent drawing and ensuring finished product quality from the source; a horizontal adjusting screw module paired with a tension monitoring sensor can sense and adjust the stretching tension in real time; combined with a replaceable mold and an electromagnetic repulsion lifting limit system, it achieves precise control of the copper wire diameter and uniform drawing, avoiding localized thinning or breakage and ensuring product consistency; an independent processing bracket and detachable mold design allow for independent optimization of each functional module.

[0014] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0016] Example

[0017] Please see Figure 1-2 Traditional copper wire drawing machines often suffer from surface defects such as scratches and cracks due to die extrusion when refining copper wire diameter, affecting conductivity and subsequent processing. The patented design achieves a balance between precise diameter control and surface protection through the coordinated design of a replaceable die and a lifting limit system. Copper wire is prone to localized thinning or breakage due to tension fluctuations during stretching. The patented design uses a horizontal adjusting screw module and tension monitoring sensors to adjust the position of the winding drum and stretching speed in real time, solving the problem of traditional equipment's inability to dynamically compensate for tension. Oxide layers and impurities on the raw material surface accelerate die wear and reduce yield. The patented design integrates a pretreatment system with a cleaning brush, air blowing device, and electric heating rod, filling the gap in the separation of cleaning and preheating in traditional processes.

[0018] Therefore, this application protects a copper wire drawing machine, which operates through a horizontally adjustable lead screw module, driving the concave bearing block 16 on it. The concave bearing block 16 drives the collecting drive motor, which in turn drives the winding drum 14 on the drive end of the collecting drive motor to rotate, thereby winding the copper wire onto the winding drum 14. At the same time, through the horizontal extension and retraction of the winding drum 14, the copper wire is evenly wound onto the winding drum 14. Simultaneously, through the stretching of the copper wire, the copper wire is inserted into the inner side of the replaceable mold. Through the extrusion of the replaceable mold, the diameter of the copper wire is changed. The repulsion electromagnet 7 magnetically repels the repulsion magnet 9, which drives the lifting adjustment plate 8 on it. The lifting adjustment plate 8 drives the set buffer spring 10 on it, which in turn squeezes the lifting slider 5, causing the lifting slider 5 to move stably along a pair of lifting limit shafts 6 inside the lifting limit groove 4, thereby achieving the extrusion and stretching of the copper wire at both ends, thereby extruding, stretching and softening the copper wire.

[0019] In summary, the process involves several steps. First, the copper wire must undergo a pretreatment process before entering the fine drawing machine. In the cleaning assembly, a cleaning brush performs initial cleaning of the copper wire surface to remove impurities. Then, the air pump in the blowing device operates, adjusting the airflow direction and intensity via adjustable louvers to further remove any remaining fine particles from the copper wire surface, ensuring its cleanliness. The preheating assembly uses an electric heating rod to preheat the copper wire to a suitable processing temperature, enhancing its plasticity during subsequent stretching.

[0020] Next, the horizontally adjustable lead screw module operates, driving the concave bearing block 16 to move horizontally. The collecting drive on the concave bearing block 16 starts, driving the winding drum 14 to rotate, winding the copper wire onto the winding drum 14. At the same time, the winding drum 14 can extend and retract horizontally, achieving uniform winding of the copper wire. During the copper wire stretching process, the copper wire is inserted into the inside of the replaceable die, and the die squeezes the copper wire, changing its diameter.

[0021] In the limiter section, the repulsion electromagnet 7 generates a magnetic repulsion force against the repulsion magnet 9. The repulsion magnet 9 drives the lifting adjustment plate 8 to move, which in turn causes the buffer spring 10 to press the lifting slider 5. The lifting slider 5 moves stably up and down along the lifting limit shaft 6 inside the lifting limit groove 4, driving the compression concave roller 11 to compress and stretch the upper and lower ends of the copper wire, softening the copper wire.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations 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.
