Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire drawing die technology, specifically a copper wire drawing die. Background Technology
[0002] Copper wire is usually drawn from hot-rolled copper rods without annealing (but smaller wires may require intermediate annealing). It can be used for weaving mesh, cables, copper brush filters, etc. Copper is one of the metals known since ancient times. With the development of production, production tools made of Q345B channel steel and natural copper were no longer sufficient. The development of production led people to find ways to obtain copper from copper mines. Copper-containing minerals are relatively common and mostly have bright and eye-catching colors. Objects made of pure copper are too soft and easily bent. When processing copper wire, drawing dies are used. When drawing copper wire, the copper wire needs to be passed through holes of decreasing size, and the thicker copper wire is drawn thinner by pulling the end of the copper wire.
[0003] However, when using existing wire drawing dies, impurities on the surface of the copper wire also enter the interior of the die along with it. As the copper wire moves inside the die, these impurities can easily fall into the die, even causing them to accumulate. Furthermore, since lubricating oil needs to be applied to the surface of the copper wire during the wire drawing process, any remaining impurities can adhere to the surface and even affect the lubrication effect. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a copper wire drawing die, which has the advantages of preventing impurities from entering the interior of the drawing die, avoiding the accumulation of impurities inside the die, and improving the quality of the copper wire after drawing, thus solving the problems mentioned in the background art.

The lifting components 6 at the upper and lower ends provide power for adjusting the position of the cleaning brush 5 on the upper and lower sides. A rotating shaft 7 is fixedly sleeved on the inner wall of the lifting component 6. The installation of the rotating shaft 7 connects the knob 8 to the lifting component 6. A knob 8 is fixedly installed at the upper end of the rotating shaft 7, which facilitates the rotation of the rotating shaft 7.
[0024] The mold body 1 includes an inlet end 101, a lubrication end 102, and an outlet end 103. The left end of the inlet end 101 is fixedly connected to the right end of the lubrication end 102, and the right end of the lubrication end 102 is fixedly connected to the left end of the outlet end 103. The lubrication end 102 is provided to connect the inlet end 101 and the outlet end 103. The inlet end 101 is installed on the upper surface of the mounting base 2.
[0025] Please see Figure 6 and Figure 7 A fixing block 9 for installing the connecting component 4 is fixedly installed on the lower end face of the mounting plate 3. The fixing block 9 is configured to provide a platform for the installation of the connecting component 4. Protrusions 10 located above the cleaning brush 5 are fixedly installed on the front and rear sides of the fixing block 9, respectively. A sleeve 11 is fixedly sleeved on the inner wall of the rear end of the mounting plate 3. A ball bearing 12 is rotatably connected to the inner side of the sleeve 11. The rotation of the ball bearing 12 on the round rod 19 strengthens the stability of the lifting and lowering movement of the mounting plate 3 at both ends. The round rod 19 is rotatably connected to the side of the ball bearing 12 away from the sleeve 11. A rear housing 13 is fixedly sleeved on the outer wall of the round rod 19. The rear housing 13 plays a protective role for the round rod 19.
[0026] The connecting component 4 includes a spring 401 and a connecting block 402. One end of the spring 401 is fixedly connected to the inner wall of the fixing block 9, and the connecting block 402 is fixedly installed on the end of the spring 401 away from the fixing block 9. The spring 401 is configured to connect the connecting block 402 and the fixing block 9. The fixing block 9 is movably mounted on the cleaning brush 5 through the connecting block 402.
[0027] Please see Figure 3 and Figure 4A locking block 14 is fixedly installed on the upper end of the cleaning brush 5, and the inner wall of the locking block 14 is movably engaged with the outer wall of the fixing block 9. Grooves 16 are respectively opened on the front and rear sides of the inner wall of the locking block 14, and the inner wall of the groove 16 is movably engaged with the outer wall of the protrusion 10. A through hole 15 is opened on the left side of the locking block 14, and the inner wall of the through hole 15 is movably sleeved with the outer wall of the connecting block 402. By changing the connection method between the through hole 15 and the connecting block 402, the cleaning brush 5 can be replaced.
[0028] The lifting assembly 6 includes a ball nut 601 and a ball screw 602. The inner wall of the ball nut 601 is threadedly connected to the outer wall of the ball screw 602. The threaded connection allows the circumferential rotation of the ball screw 602 to drive the vertical lifting motion of the ball nut 601. The outer walls of the upper and lower ends of the ball screw 602 are provided with threads in opposite directions. The inner wall of the ball screw 602 is fixedly connected to the outer wall of the rotating shaft 7. The outer wall of the rotating shaft 7 is movably connected to a front housing 17 located outside the lifting assembly 6. A bracket 18 is fixedly installed at the lower end of the front housing 17, and the lower end of the bracket 18 is fixedly connected to the upper end face of the mounting base 2.
[0029] Working principle: In use, first, adjust the position of the upper and lower cleaning brushes 5. Then, rotate the shaft 7 by holding the knob 8. The rotation of the shaft 7 simultaneously drives the upper and lower ball screws 602 to rotate. Due to the threaded connection between the ball screws 602 and the ball nuts 601, and the opposite-direction threads on the outer walls of the upper and lower ball screws 602, the rotation of the shaft 7 simultaneously moves the ball nuts 601 towards the copper wire until they contact the outer wall of the copper wire. Then, stop rotating the shaft 7. The copper wire then passes between the upper and lower cleaning brushes 5, cleaning... Brush 5 cleans impurities from the outer wall of the copper wire. After cleaning, the copper wire is then drawn sequentially from the lubrication end 102, the inlet end 101, and the outlet end 103. Finally, when the cleaning brush 5 is worn, the connecting block 402 is pressed and moved into the fixing block 9 until the connecting block 402 is separated from the through hole 15. Then, the locking block 14 can be removed from the fixing block 9, and the worn cleaning brush 5 can be replaced. Then, the spring 401 is used to push the connecting block 402 out of the through hole 15, so that the connecting component 4 can connect the locking block 14 and the fixing block 9, thus achieving the installation of the cleaning brush 5.
