An adaptive annealing device for low resistivity electrical copper wire

Abstract

This utility model discloses a low-resistivity adaptive annealing device for electrical copper wire, including a frame. A heat-collecting tube and an oiling device are vertically mounted on the frame, fitted onto the surface of the electrical copper wire. An inlet guide wheel and an outlet guide wheel are mounted on the frame, located on one side of the heat-collecting tube. A tension adjusting wheel is positioned below the heat-collecting tube on the frame, and a wire-carrying wheel and a tension adjusting wheel are positioned above the heat-collecting tube on the frame. The electrical copper wire sequentially passes around the inlet guide wheel and the tension adjusting wheel, passes through the heat-collecting tube, passes around the wire-carrying wheel and the tension adjusting wheel, passes through the oiling device, and exits around the outlet guide wheel. This utility model, by vertically aligning the heat-collecting tube and ensuring that both the tension adjusting wheels move vertically, maintains a vertical transport position for the electrical copper wire at corresponding positions. The direction of the electrical copper wire's orientation aligns with the direction of force, thus reducing bounce, decreasing transport resistance, and ensuring smooth transport.

Description

Technical Field

[0001] This utility model relates to the technical field of annealing devices, specifically to an adaptive annealing device for low resistivity electrical copper wires. Background Technology

[0002] Low resistivity electrical copper wire is a high-purity copper conductor, typically made from high-purity oxygen-free copper with a copper content greater than 99.95%, resulting in extremely low resistivity and conductivity exceeding 100% IACS. This effectively reduces power loss and improves transmission efficiency. The high conductivity and corrosion resistance of low resistivity electrical copper wire make it an ideal choice for the power and electronics fields, meeting transmission requirements in various complex environments. It is widely used in power transmission, electronic information, and electrical equipment.

[0003] Electrical copper wire undergoes cold drawing and annealing processes to achieve the required diameter and properties. During the online annealing process, the high-temperature copper wire reacts with oxygen in the air after annealing, causing an oxidation reaction that directly affects the wire's quality. Therefore, anti-oxidation treatment is necessary. In existing technologies, passing the copper wire through a nitrogen-protected heat collector tube effectively prevents oxidation. However, the high speed of the copper wire makes it prone to bouncing, increasing frictional resistance and affecting the smoothness and stability of the wiring. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a low-resistivity electrical copper wire adaptive annealing device, which solves the problem that the high copper wire conveying speed during copper wire annealing in existing technologies leads to increased frictional resistance and affects the smooth wire routing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An adaptive annealing device for low resistivity electrical copper wire includes a frame on which a heat collection tube and an oiling device are vertically mounted. An inlet guide wheel and an outlet guide wheel are mounted on the frame, located on one side of the heat collection tube. A tension adjustment wheel is positioned below the heat collection tube on the frame, and a wire guide wheel and a tension adjustment wheel are positioned above the heat collection tube on the frame. The electrical copper wire passes sequentially around the inlet guide wheel and the tension adjustment wheel, through the heat collection tube, around the wire guide wheel and the tension adjustment wheel, through the oiling device, and around the outlet guide wheel before being output.

[0007] The upright frame is vertically provided with through slots at the positions corresponding to the tension adjustment wheel one and tension adjustment wheel two. The back of the upright frame is fixed above and below the positions corresponding to the through slots, and a guide post is fixed between the two fixed posts at the corresponding positions. A slider is slidably connected to the guide post, and tension adjustment wheel one and tension adjustment wheel two are respectively installed on the two sliders.

[0008] A downward pressure spring is installed on the guide post corresponding to the tension adjustment wheel one, located above the slider. A support spring is installed on the guide post corresponding to the tension adjustment wheel two, located below the slider. Magnet one and magnet two with opposite magnetic poles are respectively installed on the opposite surfaces of the slider corresponding to the tension adjustment wheel one and the upper fixed seat, and on the opposite surfaces of the slider corresponding to the tension adjustment wheel two and the lower fixed seat.

[0009] Preferably, the infeed guide wheel and the outfeed guide wheel each include at least three guide wheels, which are equidistant in the lateral direction and staggered vertically.

[0010] Preferably, the guide wheel of the infeed guide wheel and the tension adjusting wheel are equidistant in the transverse direction.

[0011] Preferably, the cable guide wheel includes two guide wheels that are staggered vertically and are equidistant from the tension adjustment wheel in the transverse direction.

[0012] Preferably, the inlet guide wheel, outlet guide wheel, tension adjusting wheel one, tension adjusting wheel two, and cable guide wheel are all V-groove ceramic groove wheels mounted via ceramic bearings.

[0013] Preferably, the dimensions of the opposing surfaces of magnet one and magnet two are equal, the thickness of magnet one is greater than the thickness of magnet two, and magnet one is mounted on a fixed base while magnet two is mounted on a slider.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) By setting up a vertical frame, heat collection tube and oiling device, this utility model can effectively reduce the floor space and improve the utilization rate of workshop space. By setting the heat collection tube vertically, and at the same time, tension adjustment wheel one and tension adjustment wheel two move in the vertical direction, the corresponding electrical copper wires are kept in a vertical state for conveying. Due to gravity, the electrical copper wires are vertically downward, and the setting direction of the electrical copper wires is consistent with the direction of force, so that they are not easy to bounce, reduce the conveying resistance, and ensure stable conveying.

[0016] (2) Based on the tension provided by the pressure spring and the support spring to the tension adjustment wheel one and tension adjustment wheel two, this utility model provides tension by adding magnet one and magnet two through the magnetic force of repulsion between like magnetic poles, thus avoiding the problem of spring aging and fatigue affecting use.

[0021] 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.

[0022] like Figure 1-3 As shown, this utility model provides a technical solution: a low resistivity electrical copper wire adaptive annealing device, including a frame 1, on which a heat collection tube 3 and an oiling device 4 are vertically mounted and sleeved on the surface of the electrical copper wire 2. An inlet guide wheel 5 and an outlet guide wheel 6 are mounted on the frame 1 on one side of the heat collection tube 3. The inlet guide wheel 5 and the outlet guide wheel 6 each include at least three guide wheels. The guide wheels are equidistant in the horizontal direction and staggered vertically. The guide wheel of the inlet guide wheel 5 is equidistant in the horizontal direction from the tension adjustment wheel 7. The wire guide wheel 8 includes two staggered guide wheels and is equidistant in the horizontal direction from the tension adjustment wheel 9. The contact points with the electrical copper wire 2 are dispersed, the lateral movement space is limited, and bouncing is prevented.

[0023] A tension adjustment wheel 7 is installed on the support frame 1 at the position below the heat collector tube 3, and a wire guide wheel 8 and a tension adjustment wheel 9 are installed on the support frame 1 at the position above the heat collector tube 3. The inlet guide wheel 5, the outlet guide wheel 6, the tension adjustment wheel 7, the tension adjustment wheel 9, and the wire guide wheel 8 are all V-groove ceramic groove wheels installed through ceramic bearings, which have an insulating effect, reduce rotational resistance, and prevent excessive pulling of the electrical copper wire 2, causing it to deform.

[0024] The electrical copper wire 2 passes through the inlet guide wheel 5 and tension adjustment wheel 1 7 in sequence, passes through the heat collection tube 3, passes through the wire guide wheel 8 and tension adjustment wheel 2 9, passes through the oiling device 4, and passes through the outlet guide wheel 6 for output;

[0025] The upright frame 1 has vertically arranged through grooves 101 at the positions corresponding to the tension adjustment wheel 7 and tension adjustment wheel 9. The back of the upright frame 1 is fixed above and below the positions corresponding to the through grooves 101. A guide post 11 is fixed between the two corresponding fixed posts 10. A slider 12 is slidably connected to the guide post 11. The tension adjustment wheel 7 and tension adjustment wheel 9 are respectively installed on the two sliders 12.

[0026] A downward pressure spring 13 is installed on the guide post 11 corresponding to tension adjustment wheel 1 7, which is located above the slider 12. A support spring 14 is installed on the guide post 11 corresponding to tension adjustment wheel 2 9, which is located below the slider 12. Magnet 15 and magnet 2 16 with opposite magnetic poles are respectively installed on the opposite surfaces of slider 12 corresponding to tension adjustment wheel 1 7 and upper fixed seat 10, and on the opposite surfaces of slider 12 corresponding to tension adjustment wheel 2 9 and lower fixed seat 10.

[0027] Magnet 15 and Magnet 26 have the same dimensions on their opposite sides. Magnet 15 is thicker than Magnet 26. Magnet 15 is mounted on the fixed base 10 and Magnet 26 is mounted on the slider 12. Magnet 26 is thinner and lighter, so it has less impact on the movement of the slider 12.

[0028] Working principle:

[0029] The copper wire 2 passes sequentially around the inlet guide wheel 5 and tension adjustment wheel 1 7, through the heat collector tube 3, around the cable guide wheel 8 and tension adjustment wheel 2 9, through the oiling device 4, and around the outlet guide wheel 6 for output. The upright frame 1, heat collector tube 3, and oiling device 4 are vertically arranged, which can effectively reduce the footprint. At the same time, both tension adjustment wheels 1 7 and tension adjustment wheels 2 9 move vertically. Based on the tension provided by the pressure spring 13 and support spring 14, the tension adjustment wheels 1 7 and tension adjustment wheels 2 9 are provided by adding magnets 1 15 and 2 16, which provide tension through the magnetic force of repulsion between like magnetic poles. This avoids the springs aging and fatigue, which affects the use. The copper wire 2 is kept vertically conveyed in the corresponding positions. Due to gravity, it is vertically downward. The direction of the copper wire 2 is consistent with the direction of force, so it is not easy to bounce and ensures smooth conveying.
