Description

Technical Field

[0001] This invention relates to the field of wire and cable manufacturing technology, and in particular to a production equipment and method for ultra-long round copper wires for submarine cables. Background Technology

[0002] With the rapid development of marine energy development and the construction of cross-sea communication infrastructure, submarine cables, as the core transmission medium for offshore wind power grid connection systems and submarine communication networks, directly affect the safe and stable operation of the entire marine engineering system. Copper, as a metallic material with excellent electrical conductivity, is one of the main manufacturing materials for submarine cable conductors. Compared with copper wire used in ordinary power cables, copper wire for submarine cables has stricter dimensional tolerance requirements, higher mechanical strength indicators, and longer service life requirements.

[0003] Existing equipment and methods for producing ultra-long round copper wire for submarine cables have some shortcomings, as detailed below:

[0004] 1. On the one hand, since copper rods are ultra-long cables, deformation structures such as deformed parts and protrusions will inevitably appear on their surface during production, transportation and storage. In the subsequent wire drawing process, these deformation structures will have a significant impact and interference on the wire drawing process. For example, it may cause local cable drawing instability and uneven thickness, affecting the overall quality of the round copper wire. Moreover, when these deformed parts come into contact with the conveyor wheel, they will cause contact damage to the conveyor wheel, shorten the service life of the conveyor wheel and increase production costs.

[0005] 2. On the other hand, during the feeding process of the copper rod, the interaction between the traction force and its own deformation stress causes uneven stress distribution inside the copper rod. At the same time, due to the uneven stress and other factors, the copper rod is prone to conveying deviation during the traction process. This not only affects the subsequent wire drawing accuracy of the copper rod, resulting in large dimensional deviations in the produced round copper wires, which cannot meet the high precision requirements of submarine cables for round copper wires, but may also cause production equipment failures and reduce production efficiency.

The movable spring 32 is sleeved on the side wall of the guide rod 30.

[0035] This invention also proposes a method for producing ultra-long round copper wire for submarine cables, comprising:

[0036] A1. Feeding, Correction and Preheating: The copper rod 18 is passed through the forming hole 17 of the forming frame 16. The guide wheel 20 and the collecting frame 19 are used to initially guide the copper rod 18. The drive motor 23 is started to drive the rotating tube 3 to rotate. The copper rod 18 is conveyed under the action of the rotating tube 3 and the correction wheel 4. The correction mechanism corrects the conveying deviation of the copper rod 18 in real time through the elastic adjustment of the push spring 10 and the connecting spring 11. At the same time, the first heating plate 15 of the preheating mechanism preheats the copper rod 18 to alleviate the problem of uneven internal stress.

[0037] A2. Wire drawing operation: After correction and preheating, the copper rod 18 enters the wire drawing wheel 27 for wire drawing. The positioning mechanism ensures the stability of the following shaft 25 and the wire drawing wheel 27 through the synchronous frame 31 and the movable spring 32, ensuring the wire drawing accuracy. During the wire drawing process, the second heating plate 28 at one end of the following shaft 25 continuously heats the copper rod 18, further optimizing the internal structure of the copper rod 18 and making the wire drawing process more stable.

[0038] A3. Quality Inspection: During the production process, parameters such as the conveying status of the copper rod 18, the dimensional accuracy of the wire drawing, and the surface quality of the round copper wire are monitored in real time. Online inspection equipment, such as a laser diameter gauge, is used to detect diameter deviations in the round copper wire, and a visual inspection system is used to check for surface defects. If any abnormal parameters are detected, equipment parameters are adjusted or the equipment is maintained promptly to ensure that the produced ultra-long round copper wire for submarine cables meets quality standards.

[0039] When using, such as Figure 1-5 As shown, the copper rod 18 is first pulled through the forming frame 16 and makes outer circumferential contact through the forming holes 17 at both ends of the forming frame 16. This process addresses the protrusions and deformations on the sidewalls of the copper rod 18. The forming holes 17 can be replaced and adjusted according to the outer diameter of the copper rod 18. At this time, the copper rod 18 rolls in contact with the guide wheel 20 at the collecting frame 19, ensuring smooth and stable feeding of the copper rod 18. When the rotating tube 3 on the positioning frame 2 conveys the copper rod 18, the guide groove 5 on the sidewall of the rotating tube 3 slides and limits the guide block 6 on the inner wall of the correction wheel 4, which can drive the correction wheel 4 to rotate. While the tube 3 rotates synchronously, it slides on the side wall of the rotating tube 3. When the copper rod 18 deviates during the feeding process, the push spring 10 pushes the correction wheel 4 to move. The correction wheels 4 on both sides push the copper rod 18 to the center position. At the same time, the connecting spring 11 on the positioning rod 7 pushes the traction frame 8, which works synchronously with the push spring 10 to complete the correction process of the copper rod 18 during the feeding process. During this process, the drive motor 23 drives one side of the rotating tube 3 to rotate. At this time, the two drive gears 22 mesh, which can drive the two rotating tubes 3 to rotate synchronously relative to each other, and can simultaneously drive the two copper rods 18 to move synchronously.

[0040] When the copper rod 18 passes through the rotating tube 3, the mounting rod 13 is installed on one side of the fixed frame 9 through the mounting plate 14. At this time, the first heating plate 15 on the mounting rod 13 heats the rotating tube 3 to maintain the preheating treatment of the copper rod 18 during the feeding process. At the same time, when the copper rod 18 is running on the drawing wheel 27, the second heating plate 28 preheats the copper rod 18. Through traction and preheating treatment, the internal stress problem of the copper rod 18 during the feeding process can be eliminated.

[0041] At this time, the connecting frame 29 located on the wire drawing machine frame 1 provides support for the guide rod 30. At this time, the sliding frame 26 and the sliding frame 26, under the sliding limit of the adjusting groove 24, drive the synchronous frame 31 to slide on the side wall of the guide rod 30, providing support for the operation of the wire drawing wheel 27 and maintaining the stability of the wire drawing wheel 27 during operation. At this time, during the wire drawing process, due to the deformation of the copper rod 18 and the contact pressure generated during the contact process, the copper rod 18 will experience traction force fluctuations. Under the push of the movable spring 32, the tensile stress of the copper rod 18 during the wire drawing process can be kept stable.
