Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a copper wire transmission device. Background Technology

[0002] Copper wire, as an important conductive and thermally conductive material, is widely used in electronics, electrical appliances, wires and cables, precision instruments, aerospace, and many other fields. With the continuous improvement of product performance requirements in downstream industries, the demands on the surface quality, dimensional accuracy, and mechanical properties of copper wire are becoming increasingly stringent. Annealing is one of the key processes in the production and processing of copper wire. Its purpose is to eliminate internal stress generated during processing and improve the flexibility and conductivity of the copper wire. Annealed copper wire is typically heated to 300℃~600℃, a high-temperature state that stabilizes its microstructure, ensuring processing performance and precision. It needs to be rapidly and stably transferred to the next processing step.

[0003] Currently, traction devices such as traction wheels are commonly used to transport annealed high-temperature copper wires. These devices apply external force to move the wires, enabling their transfer between processing steps. However, this method of transporting high-temperature copper wires via traction devices has several significant drawbacks: First, the direct contact between the traction device and the high-temperature copper wire easily causes surface scratches and oxide scale peeling, severely impacting the wire's surface quality. Second, the traction tension of the traction device is difficult to control precisely; excessive tension can lead to wire stretching and deformation, while insufficient tension prevents stable transport, thus affecting subsequent processing accuracy and product yield. Third, current traction devices lack appropriate protective structures to address the high-temperature characteristics of the copper wires, making them susceptible to performance changes due to sudden temperature drops during transport.

[0004] Therefore, how to avoid the surface damage of high-temperature copper wire during transmission, thereby ensuring the quality of high-temperature copper wire during transmission, and at the same time avoiding the problem of copper wire quality being affected by unstable temperature during transmission, and thus ensuring the accuracy of subsequent copper wire processing and product qualification rate, is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] This utility model provides a copper wire transmission device to avoid the problem that the surface of high-temperature copper wire is easily damaged during transmission, thereby ensuring the quality of high-temperature copper wire during transmission, and thus ensuring the accuracy of subsequent copper wire processing and the product qualification rate.

[0006] According to some embodiments, this utility model provides a copper wire transmission device, comprising: A vertical tube body extends in a vertical direction, and the vertical tube body includes a top inlet and a bottom outlet that are distributed opposite to each other in a vertical direction; A feeding guide structure is connected to the top of the vertical tube body. The feeding guide structure includes a first opening and a second opening that are distributed and communicate with each other in the vertical direction. The diameter of the first opening is larger than the diameter of the second opening, and the second opening communicates with the top inlet. Multiple guide rings are arranged vertically at intervals within the vertical tube body. The sidewalls of the guide rings are fixedly connected to the inner wall of the vertical tube body, and the axis of the guide rings coincides with the axis of the vertical tube body. The guide rings are used to guide the copper wire to be transmitted along the axis of the vertical tube body.

[0007] In some embodiments, the vertical tube body is a corundum ceramic tube or an alloy tube.

[0008] In some embodiments, the cross-section of the feed guide structure is funnel-shaped, and the diameter of the second opening is equal to the diameter of the top inlet.

[0009] In some embodiments, the number of guide rings is 3 to 5.

[0010] In some embodiments, the distance between adjacent guide rings in the vertical direction is 50mm to 100mm.

[0011] In some embodiments, the inner diameter of the guide ring is 0.2 mm to 0.5 mm larger than the outer diameter of the copper wire to be transmitted.

[0012] In some embodiments, it also includes: A discharge buffer structure is provided at the bottom end of the vertical pipe body. The cross-section of the discharge buffer structure is arc-shaped, and the discharge buffer structure includes a vertical opening communicating with the bottom outlet and a horizontal opening opposite to the vertical opening.

[0013] In some embodiments, it also includes: A top connecting flange is provided at the top of the vertical pipe body, and the top connecting flange connects the feed guide structure and the vertical pipe body; A bottom connecting flange is provided at the bottom end of the vertical pipe body, and the bottom connecting flange connects the discharge buffer structure and the vertical pipe body.

[0014] In some embodiments, it also includes: The insulation layer is at least wrapped around the outer wall of the vertical pipe body.

[0015] In some embodiments, the insulation layer is an aluminum silicate cotton insulation layer, and the thickness of the aluminum silicate cotton insulation layer is 10mm~20mm.

[0016] The copper wire transmission device provided by this utility model, by setting a vertical tube body extending in the vertical direction, a feeding guide structure communicating with the top opening of the vertical tube body, and a guide ring set in the vertical tube body, enables the transmission of copper wire (such as high-temperature copper wire after annealing) within the vertical tube body without traction tension by utilizing the weight of the copper wire itself. This eliminates the traction structure in the copper wire transmission process, avoids problems such as scratches on the copper wire surface and oxide scale peeling caused by direct contact between the copper wire and the traction structure, and ensures the quality of the copper wire during the transmission process. Furthermore, the copper wire is guided into the vertical tube body through the feeding guide structure, and the transmission path of the copper wire within the vertical tube body is limited by the guide ring. This ensures that the copper wire moves stably along the axial direction of the vertical tube body, avoiding collisions and friction between the copper wire and the inner wall of the vertical tube body during transmission. In conjunction with the gravity transmission mode without traction tension, the problem of uneven traction tension in the traction structure is fundamentally solved, preventing the copper wire from stretching or getting stuck during transmission, thus ensuring the accuracy of subsequent copper wire processing and the product qualification rate.

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.

[0019] Explanation of reference numerals in the attached figures 10 Vertical pipe body 11 Feeding Guide Structure 12 insulation layers 13 guide rings 14 Discharge buffer structure 15 copper wire 16 Top Connecting Flange Detailed Implementation The specific embodiments of the copper wire transmission device provided by this utility model will be described in detail below with reference to the accompanying drawings.

[0020] This specific embodiment provides a copper wire transmission device. Figure 1 This is a structural schematic diagram of the copper wire transmission device in a specific embodiment of this utility model. (See attached diagram.) Figure 1 As shown, the copper wire transmission device includes: A vertical tube body 10 extends in a vertical direction, and the vertical tube body 10 includes a top inlet and a bottom outlet that are distributed opposite to each other in a vertical direction; The feed guide structure 11 is connected to the top end of the vertical tube body 10. The feed guide structure 11 includes a first opening and a second opening that are distributed and communicate with each other in the vertical direction. The diameter of the first opening is larger than the diameter of the second opening. The second opening is connected to the top inlet. Multiple guide rings 13 are arranged at intervals in the vertical tube body 10 along the vertical direction. The sidewall of the guide ring 13 is fixedly connected to the inner wall of the vertical tube body 10, and the axis of the guide ring 13 coincides with the axis of the vertical tube body 10. The guide ring 13 is used to guide the copper wire 15 to be transmitted along the axis of the vertical tube body 10.

[0021] Specifically, the copper wire conveying device is used to convey copper wire at room temperature or high-temperature copper wire after annealing. In this specific embodiment, the high-temperature copper wire refers to copper wire with a temperature between 300℃ and 600℃. The copper wire conveying device includes a vertical tube body 10 extending vertically, a feed guide structure 11 connected to and communicating with the top of the vertical tube body 10, and a plurality of guide rings 13 disposed within the tube of the vertical tube body 10. When the copper wire 15 is conveyed using the copper wire conveying device, the copper wire 15 enters the feed guide structure 11 through the first opening, is conveyed through the second opening of the feed guide structure 11 to the top inlet of the vertical tube body 10, and then is conveyed vertically from the top opening to the bottom outlet of the vertical tube body 10.

[0022] The feeding guide structure 11 extends vertically, and the diameter of the first opening in the feeding guide structure is larger than the diameter of the second opening. The second opening communicates with the top inlet. The larger diameter of the first opening facilitates the smooth entry of the copper wire 15 into the feeding guide structure 11, while the smaller diameter of the second opening facilitates the guiding of the copper wire 15 into the vertical tube body 10. The vertical tube body 10 extends vertically, allowing the copper wire 15 located within the vertical tube body 10 to automatically fall from the top inlet to the bottom outlet under gravity, eliminating the need for an additional traction structure to move the copper wire 15. This fundamentally avoids the problem of uneven traction tension, preventing the copper wire from stretching or jamming during transmission, and ensuring the accuracy and product qualification rate of subsequent copper wire processing. Multiple guide rings 13 are disposed inside the vertical tube body 10, and are arranged vertically at intervals and aligned, with the axis of each guide ring 13 coinciding with the axis of the vertical tube body 10. in, Figure 1 The solid red line in the diagram represents the axis of the vertical tube body 10. By providing multiple guide rings 13, which protrude from the inner wall of the vertical tube body 10 and whose axes coincide with the axis of the vertical tube body 10, the movement path of the copper wire 15 within the vertical tube body 10 is limited. That is, the copper wire 15 can only fall along the axial direction of the vertical tube body 10 and pass through the area within the ring formed by the guide rings 13. This ensures the stability of the copper wire 15's movement within the vertical tube body 10 and avoids collisions and friction between the copper wire 15 and the inner wall of the vertical tube body 10, thus preventing scratches, oxide peeling, and other damage to the surface of the copper wire 15, significantly improving the surface quality of the copper wire 15 after transmission.

[0023] In some embodiments, the vertical tube body 10 is a corundum ceramic tube or an alloy tube.

[0024] Specifically, corundum ceramic tubes or alloy tubes are used as the vertical tube body 10 because both corundum ceramic tubes and alloy tubes have the characteristics of high temperature resistance, oxidation resistance, and corrosion resistance, which can prevent the high-temperature copper wire 15 from damaging the vertical tube body 10. The inner diameter of the vertical tube body 10 should be larger than the outer diameter of the copper wire 15 to allow the copper wire 15 to fall freely within the vertical tube body 10. In one example, the inner diameter of the vertical tube body 10 is 0.5mm to 1mm larger than the outer diameter of the copper wire 15. In another example, the vertical tube body 10 is a straight tube extending vertically.

[0025] In some embodiments, the feed guide structure 11 has a funnel-shaped cross-section, and the diameter of the second opening is equal to the diameter of the top inlet.

[0026] Specifically, the width of the feed guide structure gradually decreases along the vertical direction. By setting the feed guide structure 11 in a funnel shape (i.e., trumpet shape), the diameter of the first opening is larger than the diameter of the second opening (for example, the diameter of the first opening is 3 to 5 times the diameter of the second opening), and the diameter of the second opening is equal to the diameter of the top inlet, to ensure that the copper wire 15 can smoothly pass through the feed guide structure 11 and enter the vertical tube body 10. The diameter of the top inlet, the diameter of the bottom outlet, and the inner diameter of the vertical tube body 10 are all equal. In one example, the inner wall of the feed guide structure 11 is an arc-shaped inner wall to avoid scratching or other damage to the copper wire 15. The material of the feed guide structure 11 can be the same as the material of the vertical tube body 10, for example, both being corundum ceramic or alloy.

[0027] In some embodiments, the number of guide rings 13 is 3 to 5.

[0028] In some embodiments, the distance between adjacent guide rings 13 in the vertical direction is 50mm to 100mm.

[0029] In some embodiments, the inner diameter of the guide ring 13 is 0.2 mm to 0.5 mm larger than the outer diameter of the copper wire 15 to be transmitted.

[0030] For example, such as Figure 1 As shown, the vertical tube body 10 has four guide rings 13 arranged at intervals along the vertical direction, and the four guide rings 13 are equally spaced within the vertical tube body 10, with a distance of 50mm to 100mm between any two adjacent guide rings 13. By making the inner diameter of the guide ring 13 0.2mm to 0.5mm larger than the outer diameter of the copper wire 15 to be transmitted, it can guide the transmission path of the copper wire 15 within the vertical tube body 10 without causing excessive resistance to the falling motion of the copper wire 15 under the action of gravity. In one example, the guide ring 13 can be made of a wear-resistant material to improve the service life of the copper wire transmission device.

[0031] In some embodiments, the copper wire transmission device further includes: The discharge buffer structure 14 is disposed at the bottom end of the vertical pipe body 10. The cross-section of the discharge buffer structure 14 is arc-shaped, and the discharge buffer structure 14 includes a vertical opening communicating with the bottom outlet and a horizontal opening opposite to the vertical opening.

[0032] Specifically, such as Figure 1 As shown, the bottom end of the vertical tube body 10 is connected to an arc-shaped discharge buffer structure 14. The discharge buffer structure 14 includes a vertical section, a horizontal section, and an arc-shaped connecting section for connecting the vertical section and the horizontal section. The vertical opening is located on the vertical section and communicates with the bottom outlet of the vertical tube body 10. The horizontal opening is located on the horizontal section and extends horizontally. The copper wire 15 enters the discharge buffer structure 14 from the bottom outlet of the vertical tube body 10 through the vertical opening and is transmitted to the horizontal opening for output from the discharge buffer structure 14. By setting the arc-shaped discharge buffer structure 14 at the bottom end of the vertical tube body 10, the gravitational potential energy of the copper wire 15 can be released smoothly, reducing the impact force at the moment of discharge of the copper wire 15 (i.e., the moment of output from the copper wire transmission device), and preventing the copper wire 15 from bending or being damaged at the end. Figure 1 The green dashed box in the diagram is only to indicate the position of the discharge buffer structure 14; in the actual copper wire transmission device, the green dashed box does not exist.

[0033] In some embodiments, the copper wire transmission device further includes: A top connecting flange 16 is disposed at the top end of the vertical pipe body 10, and the top connecting flange 16 connects the feed guide structure 11 and the vertical pipe body 10. A bottom connecting flange is provided at the bottom end of the vertical pipe body 10, and the bottom connecting flange connects the discharge buffer structure 14 and the vertical pipe body 10.

[0034] In some embodiments, the copper wire transmission device further includes: The insulation layer 12 is at least wrapped around the outer wall of the vertical pipe body 10.

[0035] In some embodiments, the insulation layer 12 is an aluminum silicate cotton insulation layer, and the thickness of the aluminum silicate cotton insulation layer is 10mm~20mm.

[0036] For example, the insulation layer 12 continuously wraps the outer wall of the vertical pipe body 10 and the outer wall of the discharge buffer structure 14, thereby effectively reducing the temperature loss of the copper wire 15 during the transmission process, maintaining the temperature stability of the high-temperature copper wire 15 during the transmission process, and ensuring that its mechanical properties meet the requirements of subsequent processing.

[0037] The copper wire conveying device provided in this specific embodiment, by setting a vertical tube body extending in the vertical direction, a feeding guide structure communicating with the top opening of the vertical tube body, and a guide ring set in the vertical tube body, enables the copper wire (e.g., high-temperature copper wire after annealing) to be conveyed in the vertical tube body without traction tension by utilizing its own weight. This eliminates the traction structure in the copper wire conveying process, avoids problems such as scratches on the copper wire surface and oxide scale peeling caused by direct contact between the copper wire and the traction structure, and ensures the quality of the copper wire during the conveying process. Furthermore, the copper wire is guided into the vertical tube body through the feeding guide structure, and the transmission path of the copper wire within the vertical tube body is limited by the guide ring. This ensures that the copper wire moves stably along the axial direction of the vertical tube body, avoiding collisions and friction between the copper wire and the inner wall of the vertical tube body during transmission. In conjunction with the gravity transmission mode without traction tension, the problem of uneven traction tension in the traction structure is fundamentally solved, preventing the copper wire from stretching or getting stuck during transmission, thus ensuring the accuracy of subsequent copper wire processing and the product qualification rate.
