Abstract
Description
Technical Field
[0001] This invention relates to the field of copper wire drawing technology, and more particularly to a drawing machine for the production of silver-plated copper wire. Background Technology
[0002] The silver-plated copper wire drawing machine is a key piece of equipment in the production of silver-plated copper wire. It mainly applies tension to the copper wire through a die to achieve wire diameter reduction, density increase and surface finishing. The equipment includes systems for wire feeding, drawing, lubrication and cooling, and wire take-up. During the drawing process, the tension and speed must be precisely controlled to ensure that the silver plating layer is uniform and does not fall off, and finally produce silver-plated copper wire with high conductivity and high surface quality that meets the specifications.
[0003] Existing silver-plated copper wire drawing machines generally lack a dedicated copper shavings cleaning structure. During the production process, the large amount of copper shavings generated by the high-speed friction between the drawing die and the copper wire easily adheres to the surface of the copper wire or accumulates at the entrance of the drawing tube. These residual copper shavings not only scratch the surface of the copper wire, leading to quality defects such as uneven plating, bubbles, and peeling in subsequent silver plating processes, but also exacerbate die wear and drawing tube blockage, causing abnormal fluctuations in drawing tension and increasing the risk of wire breakage. Since there is no automatic cleaning function, cleaning copper shavings requires manual operation after the machine is stopped, which seriously affects the continuity of production, reduces production efficiency, and increases labor costs, making it difficult to meet the actual needs of modern silver-plated copper wire production for high precision, high efficiency, and low loss.
[0004] Based on this, a drawing machine for the production of silver-plated copper wire is proposed. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Please see Figures 1-6 The present invention provides a technical solution:
[0029] A drawing machine for producing silver-plated copper wire includes a base 1. A fixing block 2 is connected to the upper end of the base 1. Two fixing blocks 2 are symmetrically connected to both ends of the upper surface of the base 1. When the copper wire is connected to the fixing block 2, both ends of the copper wire need to be simultaneously pulled and limited to ensure the copper wire is taut and improve drawing accuracy. A drawing cylinder 5 is connected to the fixing block 2. The telescopic end of the drawing cylinder 5 passes through the fixing block 2 and is connected to a drawing plate 4. A clamping block 11 is connected to the drawing plate 4. The clamping block 11 can clamp and draw the copper wire. This drawing machine is suitable for drawing shorter copper wires. For longer copper wires, continuous traction by a rotating roller can achieve drawing. The clamping block 11 structure for clamping the copper wire is a relatively mature existing technology, so it is directly quoted to avoid further description. A connecting plate 7 is connected to the upper end of the base 1. A sliding groove 13 is slidably connected to one side of the connecting plate 7. The groove 13 has a vertical groove. The sliding groove 13 is connected to a sleeve block 8 through a connecting block 14. The sleeve block 8 is fitted onto the copper wire. A drawing tube 24 is rotatably connected to the sleeve block 8. The sleeve block 8 is fitted onto the drawing tube 24. A connecting frame 10 is connected to one side of the drawing tube 24. A cleaning ring 9 is connected to the other end of the connecting frame 10. A cleaning brush is connected inside the cleaning ring 9. The cleaning brush can clean the dust and impurities on the surface of the copper wire when it is being drawn. When the drawing stops, it can also clean the copper shavings on the copper wire. A conical wheel 16 is connected to one end of the drawing tube 24. The conical wheel 16 is connected to the end of the drawing tube 24 closest to the drawing plate 4. A transmission mechanism is connected to the connecting plate 7 to drive the cleaning ring 9 to move and rotate, thereby cleaning the copper shavings at the copper wire drawing position.
[0030] Specifically, such as Figure 1 As shown, a sliding column 3 is connected between the fixed blocks 2, and a slider 6 is connected to the outside of the pulling plate 4. The slider 6 is slidably connected to the sliding column 3. By setting the sliding column 3, the translational stability of the structure of the pulling plate 4 during the pulling of copper wire is improved.
[0031] Specifically, such as Figure 5 As shown, a sliding clamp 27 is connected to one side of the slide bar 13, and a slide rail 12 is connected to the connecting plate 7. The sliding clamp 27 is slidably connected to the slide rail 12. The stability of the horizontal movement of the slide bar 13 is improved by setting the sliding clamp 27.
[0032] Specifically, such as Figure 5 As shown, one end of the pull tube 24 is connected to a snap ring 25, and one end of the sleeve block 8 is connected to a connecting wheel 26. The snap ring 25 is rotatably connected to the connecting wheel 26. The connecting wheel 26 limits the snap ring 25, preventing the snap ring 25 from separating from the connecting wheel 26 and ensuring that the snap ring 25 can rotate around the connecting wheel 26.
[0033] Specifically, such as Figure 5As shown, a spring 17 is connected between the conical wheel 16 and the sleeve block 8. The spring 17 is sleeved on the outside of the pull tube 24. By setting the spring 17, the conical wheel 16 can be reset after rotation, thereby resetting the cleaning ring 9 to its initial state.
[0034] Specifically, such as Figure 4 and Figure 5 As shown, the transmission mechanism includes a cleaning cylinder 20, which is rotatably connected to one side of the connecting plate 7. By extending and retracting the cleaning cylinder 20, the cleaning ring 9 can be moved to the copper shavings position and rotated to complete the cleaning. The cleaning effect is better by rotating than by horizontal scraping. The extension end of the cleaning cylinder 20 is connected to a slide rod 19, which is vertically connected to one end of the extension end of the cleaning cylinder 20. The connecting plate 7 has a bending groove 15, which is L-shaped. The slide rod 19 is slidably connected to the bending groove 15 and the slide bar 13.
[0035] A conical wheel 18 is rotatably connected to one side of the connecting plate 7. A winding wheel 30 is connected to one side of the conical wheel 18. A traction belt 33 is connected to the winding wheel 30. By tractioning the traction belt 33, the winding wheel 30 can be rotated. One end of the traction belt 33 is connected to one side of the connecting plate 7 through the traction frame 23. A spring 32 is connected to one side of the winding wheel 30. The spring 32 enables the structure to be reset without external force after the winding wheel 30 rotates.
[0036] Specifically, such as Figure 4 As shown, a fixed sleeve 21 is connected to the cleaning cylinder 20, and a deflection shaft 22 is connected to one side of the connecting plate 7. The fixed sleeve 21 is rotatably connected to the deflection shaft 22. By setting the fixed sleeve 21, the structural connection of the cleaning cylinder 20 is improved. When the cleaning cylinder 20 extends or retracts, the cleaning cylinder 20 will rotate around the deflection shaft 22 at the same time.
[0037] Specifically, such as Figure 5 and Figure 6 As shown, a connecting rod 28 is connected to one side of the connecting plate 7, and a connecting plate 29 is connected to the connecting rod 28. The winding wheel 30 is rotatably connected to the connecting plate 29 through the rotating column 31. One end of the spring 32 is connected to the connecting plate 29. The connecting rod 28 and the traction frame 23 can limit one end of the traction belt 33, so that when the sliding rod 19 moves, it can contact the traction belt 33, thereby driving the traction belt 33 to move, causing the winding wheel 30 to rotate. The traction belt 33 led out from the winding wheel 30 is connected to the traction frame 23 through the connecting rod 28.
[0038] In summary, the drawing machine for producing silver-plated copper wire provided in this embodiment, when the silver-plated copper wire needs to be drawn, passes the copper wire through the drawing plate 4 and the fixing block 2, controls the clamping block 11 to clamp and fix the copper wire, and then controls the drawing cylinder 5 to retract, thereby drawing the copper wire. The drawing tube 24 completes the plastic deformation of the copper wire, thereby achieving the reduction of the copper wire diameter and the strengthening of its mechanical properties.
[0039] However, during the drawing process, copper shavings will be generated at one end of the drawing tube 24. These copper shavings adhere to the copper wire at one end of the drawing tube 24, which can easily cause blockage of the drawing tube 24 and affect the drawing accuracy. At this time, the drawing cylinder 5 can be stopped at regular intervals, and the copper shavings generated during the drawing process can be cleaned and recycled, thereby improving the drawing quality.
[0040] When cleaning copper shavings, the cleaning cylinder 20 can be activated to extend the cylinder and push the slide rod 19 to move horizontally on the bending groove 15. At this time, the slide rod 19 is connected to the groove on the slide bar 13. When the slide rod 19 moves horizontally, the slide bar 13 also moves horizontally, and the slide rod 19 will not slide in the groove on the slide bar 13. The slide rod 19 abuts against the uppermost end of the groove on the slide bar 13. When the slide bar 13 moves horizontally, the sleeve block 8 moves horizontally simultaneously, and the connecting frame 10 pulls the cleaning ring 9 horizontally. At this time, both the sleeve block 8 and the cleaning ring 9 move towards the pulling plate 4. The end of the pulling tube 24 away from the pulling plate 4 starts to move from the copper wire pulling endpoint towards the pulling plate 4, and the cleaning ring 9 starts to move towards the pulling endpoint. When the slide rod 19 finishes moving horizontally, the cleaning ring 9 just moves to the pulling endpoint position, and the brush inside the cleaning ring 9 abuts against the copper shavings.
[0041] After the slide bar 19 has moved horizontally, the conical wheel 16 connected to one end of the pull tube 24 abuts against the conical wheel 18. When the conical wheel 18 rotates, it can synchronously drive the conical wheel 16 to rotate.
[0042] As the cleaning cylinder 20 continues to extend, the slide rod 19 enters the vertical part of the bending groove 15 and begins to move vertically. The slide rod 19 moves downward along the groove on the slide bar 13. When the slide rod 19 moves downward, the slide rod 19 structure contacts the traction belt 33, thereby driving the traction belt 33 to rotate the winding wheel 30. At this time, the spring 2 32 structure begins to store force. When the winding wheel 30 rotates, it can synchronously drive the conical wheel 2 18 to rotate. The conical wheel 2 18 drives the conical wheel 16 to rotate. Relying on the rotation of the cleaning ring 9 connected to one side of the conical wheel 16, the copper shavings attached to the copper wire are cleaned, avoiding a large amount of copper shavings adhering to the copper wire during the drawing process, improving the cleanliness of the copper wire, and thus improving the subsequent drawing quality. During the cleaning process, the spring 17 undergoes elastic deformation with the rotation of the drawing tube 24 to store force.
[0043] When the slide bar 19 moves vertically downwards to contact one end of the bending groove 15, the cleaning cylinder 20 extends to its maximum state. At this time, the cleaning ring 9 also completes the cleaning of the copper wire. Then, the cleaning cylinder 20 begins to retract. At this time, the slide bar 19 structure drives the sleeve block 8 and the drawing tube 24 to reset, and drives the drawing tube 24 to the end position of the drawing. Relying on the spring 17 and the spring 32, the conical wheel 18 and the cleaning ring 9 can be driven to reset and rotate respectively. When the cleaning cylinder 20 retracts to its maximum state, all structures of the drawing machine have completed the reset. At this time, the drawing cylinder 5 starts to operate and continues to draw the copper wire.
[0044] Removing copper shavings generated during the copper wire drawing process can prevent them from scratching the surface of the copper wire, and prevent defects such as uneven coverage, bubbles, or peeling of the silver plating layer, thus ensuring product quality. At the same time, it can reduce wear and blockage caused by copper shavings entering the mold and transmission components, extend the life of the mold and equipment, and reduce maintenance costs. In addition, removing copper shavings can stabilize the drawing tension, avoid wire breakage caused by abnormal friction or diameter fluctuations, improve production continuity, and reduce raw material waste and production interruption losses.
[0045] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
