Description

Technical Field

[0001] The present invention relates to the technical field of copper wire drawing, and in particular to a copper wire drawing device and a copper wire drawing method. Background Art

[0002] Copper wire drawing technology is a critical component of metalworking. Traditional devices typically utilize a combination of a fixed winding structure and independent drawing modules. However, in actual production, the winding mechanism is susceptible to fluctuations in wire tension, resulting in unstable power transmission. This is particularly true at high speeds or when material specifications vary. This can lead to a mismatch between the winding speed and the drawing rate, causing wire breakage or surface damage. Furthermore, existing equipment often relies on manual experience to adjust lubrication intensity, making it difficult to respond in real time to dynamic load changes during the drawing process. This can result in insufficient or excessive lubrication, impacting both mold life and production efficiency.

[0003] On the other hand, traditional guide mechanisms are mostly fixed designs, requiring downtime and disassembly to adjust the wire path, making them unable to quickly adapt to the processing needs of copper wires of different diameters. Furthermore, the processing environment control method is limited, lacking a coordinated mechanism for inert gas protection and uniform cooling, which can easily lead to surface oxidation or localized overheating of the copper material. In terms of safety protection, existing technologies mostly rely on electronic sensor monitoring, which carries the risk of signal delays or misjudgment. Once an abnormal load occurs, it is difficult to achieve immediate braking and physical interlocking protection, posing a risk of equipment damage and operational safety. Therefore, we propose a copper wire drawing device and drawing method to address this problem. Summary of the Invention

[0017] The present invention also provides a copper wire drawing method, which is applied to the above-mentioned copper wire drawing device and comprises the following steps:

[0018] S1: Pull out one end of the copper wire on the unwinding wheel, pass it through the left guide mechanism, the left sealing ring, each drawing ring, the right sealing ring and the right guide mechanism in sequence, and then fix it to the outside of the reel;

[0019] S2: Open the control valve to allow the inert gas in the compressed gas storage tank to enter between the upper shell and the lower shell;

[0020] S3: Start the driving motor to drive the rotating column to rotate. The rotating column drives the circular shell to rotate synchronously through the cooperation of the limiting groove and the limiting protrusion. The circular shell drives the connecting column to rotate through the cooperation of the spiral groove and the spiral strip, and then drives the driving shaft and the winding wheel to rotate, thereby realizing the winding of the copper wire, so that multiple drawing rings can realize continuous wire drawing of the copper guide wire;

[0021] S4. Start the water pump to introduce the lubricating liquid into the nozzle through the vertical pipe and spray it out from multiple nozzles to lubricate the copper wire and the wire drawing ring;

[0022] S5. During the wire drawing process, the wire drawing ring and the take-up wheel tighten the copper wire, so that both ends of the copper wire generate tension on the wire drawing ring and the take-up wheel. The wire drawing ring is subjected to the tension, thereby driving the positioning frame to move to the right, thereby compressing the connecting spring and increasing the pressure value monitored by the first pressure sensor. The controller adjusts the power of the water pump according to the pressure value monitored by the first pressure sensor. As the pressure increases, the amount of lubricating fluid sprayed by the water pump increases, thereby improving the lubrication effect on the wire and the wire drawing ring, and preventing the copper wire from breaking.

[0023] S6. When the winding wheel is subjected to tension, it is converted into rotational resistance of the connecting column, thereby causing relative rotation between the connecting column and the circular shell. The spiral strip on the outside of the connecting column drives the circular shell forward by cooperating with the spiral groove, and then drives the moving ring forward. The moving ring drives the mounting ring to move forward synchronously through the abutment of multiple positioning wheels, and compresses the reset spring, so that the pressure sensed by the second pressure sensor increases. The control panel controls the operating speed of the drive motor according to the pressure value monitored by the second pressure sensor. When the pressure value monitored by the second pressure sensor increases, the control panel controls the output speed of the drive motor to decrease, thereby slowing down the winding speed to avoid excessive speed affecting the wire drawing effect. When the L rod and the pressure plate are driven to move horizontally through the mounting ring, when the pressure plate contacts the stop button, the control panel receives a signal and controls the drive motor to stop running, thereby avoiding breakage of the copper wire.

[0024] Compared with the prior art, the present invention provides a copper wire drawing device and a wire drawing method, which have the following beneficial effects:

[0025] (1) The coordination structure of the spiral strip and the spiral groove achieves the stability and adaptive adjustment function of power transmission during the winding process. When the tension of the copper wire changes, the relative movement between the connecting column and the round shell can automatically adjust the winding speed and force, effectively buffering the instantaneous impact load and reducing the risk of wire breakage caused by sudden changes in tension.

[0026] (2) It adopts multi-level pressure monitoring and linkage control. The first pressure sensor senses the stress state of the wire drawing ring in real time, and the controller dynamically adjusts the working intensity of the spray mechanism to achieve intelligent matching of the lubricant supply and the wire tension. When the wire drawing load increases, the system automatically increases the lubricant spraying amount, effectively reducing the friction coefficient and taking away heat, avoiding material damage caused by local overheating or insufficient lubrication. This closed-loop control mechanism not only extends the service life of the wire drawing die, but also automatically adapts the process parameters according to the processing requirements of wires of different specifications, greatly improving the versatility and processing accuracy of the equipment.

[0027] (3) The guide mechanism drives the symmetrical slide plate through a bidirectional screw to achieve synchronous fine-tuning of the position of multiple sets of guide wheels. The operator can quickly complete the precise positioning of the wire path through the knob to adapt to the production needs of copper wires of different diameters. The cooperation between the limit rod and the slide hole ensures the stability of the position adjustment, and the rigid support of the positioning plate enhances the mechanism's ability to resist deformation. This modular design enables the equipment to meet both conventional production needs and the flexibility to cope with the processing of special specifications of products, effectively shortening the changeover time and improving the adaptability and utilization rate of the production line.

[0028] (4) The synergistic effect of the inflatable sealing structure and the spray cooling system constructs a complete process environment control system. Inert gas is filled between the upper shell and the lower shell to form a protective layer, effectively isolating the air to prevent copper oxidation. At the same time, the spray barrel realizes all-round cooling and lubrication through multiple nozzles. The linkage design of the compressed gas storage tank and the control valve ensures a stable supply of gas pressure, and the independent setting of the exhaust pipe and the drain pipe realizes gas-liquid separation and discharge. This integrated environmental control solution not only ensures the cleanliness of the processed surface, but also reduces material stress through temperature control, significantly improving the surface quality and mechanical properties of the product.

[0029] (5) The monitoring mechanism detects the load status of the winding system in real time through the second pressure sensor. When the tension exceeds the set threshold, the moving ring pushes the mounting ring to compress the reset spring to trigger the pressure signal. The linkage design of the L rod and the pressure plate automatically presses the stop button when overloaded to achieve emergency braking of the drive motor. The coordination of the guide rod and the stabilizer frame ensures the movement accuracy of the detection element, and the buffer structure of the arc plate and the telescopic rod avoids instantaneous impact damage to the sensor. This combination of mechanical safety interlock and electrical control builds a reliable safety protection system, which maximizes the safety of operators and the integrity of the equipment.

[0059] The present invention also provides a copper wire drawing method, which is applied to the above-mentioned copper wire drawing device and comprises the following steps:

[0060] S1: Pull out one end of the copper wire from the unwinding wheel 302, pass it through the left guide mechanism 2, the left sealing ring 402, each drawing ring 406, the right sealing ring 402 and the right guide mechanism 2 in sequence, and then fix it to the outside of the reel 702;

[0061] S2: Open the control valve 504 to allow the inert gas in the compressed gas storage tank 502 to enter between the upper shell 5 and the lower shell 4;

[0062] S3: Start the driving motor 706 to drive the rotating column 707 to rotate. The rotating column 707 drives the circular shell 9 to rotate synchronously through the cooperation between the limiting groove 708 and the limiting protrusion 902. The circular shell 9 drives the connecting column 8 to rotate through the cooperation between the spiral groove 901 and the spiral strip 801, thereby driving the driving shaft 703 and the winding wheel 702 to rotate, thereby realizing the winding of the copper wire, so that the multiple drawing rings 406 can realize the continuous drawing process of the copper guide wire;

[0063] S4. Start the water pump 505 to introduce the lubricating liquid into the nozzle 507 through the vertical pipe and spray it out from multiple nozzles to lubricate the copper wire and the wire drawing ring 406;

[0064] S5. During the wire drawing process, the wire drawing ring 406 and the winding wheel 702 tighten the copper wire, so that both ends of the copper wire generate tension on the wire drawing ring 406 and the winding wheel 702. The wire drawing ring 406 is subjected to the tension, thereby driving the positioning frame 405 to move to the right, thereby compressing the connecting spring 411 and increasing the pressure value monitored by the first pressure sensor 410. The controller 401 adjusts the power of the water pump 505 according to the pressure value monitored by the first pressure sensor 410. As the pressure increases, the amount of lubricating liquid sprayed by the water pump 505 increases, thereby improving the lubrication effect on the wire and the wire drawing ring 406 and preventing the copper wire from breaking.

[0065] S6. When the winding wheel 702 is subjected to tension, it is converted into rotational resistance of the connecting column 8, thereby causing relative rotation between the connecting column 8 and the circular shell 9. The spiral strip 801 on the outside of the connecting column 8 drives the circular shell 9 to move forward by cooperating with the spiral groove 901, and then drives the moving ring 903 to move forward. The moving ring 903 drives the mounting ring 17 to move forward synchronously through the abutment of multiple positioning wheels 21, and compresses the reset spring 15, so that the pressure sensed by the second pressure sensor 12 increases. The control panel 10 controls the operating speed of the drive motor 706 according to the pressure value monitored by the second pressure sensor 12. When the pressure value monitored by the second pressure sensor 12 increases, the control panel 10 controls the output speed of the drive motor 706 to decrease, thereby slowing down the winding speed to avoid excessive speed affecting the wire drawing effect. When the L rod 18 and the pressure plate 19 are driven to move horizontally through the mounting ring 17, when the pressure plate 19 contacts the stop button 11, the control panel 10 receives the signal and controls the drive motor 706 to stop running, thereby avoiding the copper wire from breaking.

[0066] In this embodiment, the bidirectional screw 206 can be driven to rotate by manually rotating the knob 207, and the distance between the two drive plates 204 can be adjusted through the threaded transmission with the two drive plates 204, thereby adjusting the distance between the guide wheels 202 to adapt to the guidance of copper wires of different thicknesses. The cooperation of multiple guide mechanisms 2 can achieve stable guidance of the copper wires.

[0067] By pushing the square plate 604 downward and compressing the compression spring 607, the square plate 604 drives the two card plates 601 to rotate through the two connecting rods 603, so that the card plate 601 is disengaged from the card slot, releasing the fixation to the upper shell 5, and then starting upward and taking out the upper shell 5 to facilitate the replacement of the drawing ring 406 in the positioning frame 405, and inserting the plug plate 508 into the corresponding slot 413 to achieve the docking of the upper shell 5 and the lower shell 4, and then loosening the square plate 604, so that the square plate 604 moves upward under the action of the compression spring 607, and drives the two card plates 601 to rotate in the opposite direction, and only needs to be stuck in the card slot to achieve the fixation of the upper shell 5 and the lower shell 4.
