Description

Technical Field

[0001] This invention belongs to the field of cable stranding technology, specifically a conductor surface treatment device and method for cable manufacturing. Background Technology

[0002] In the cable manufacturing process, conductor stranding is one of the core processes. It involves twisting multiple metal single wires (such as copper or aluminum single wires) around a central axis to form a stranded conductor with a specific cross-section and mechanical strength to meet the requirements of cable transmission performance and laying adaptability.

[0003] However, internal stress is inevitably generated during the stranding process. When the single wire rotates with the stranding equipment, it will undergo torsional deformation, resulting in misalignment of the internal lattice structure and the formation of torsional stress. On the other hand, there are differences in the linear velocity of the single wires at different radii during the stranding process. The outer single wires need to withstand greater tensile force, while the inner single wires are compressed, which in turn generates radially distributed tension. In addition, the metal material itself has elastic recovery characteristics. The stranded single wires cannot fully recover due to deformation, leaving residual stress inside the conductor.

[0004] Stress can reduce the conductivity of stranded conductors. Internal lattice misalignment increases electron transport resistance, raising conductor resistivity and failing to meet cable transmission efficiency requirements. Stress concentration can easily lead to the deterioration of conductor mechanical properties, such as reduced ductility and increased brittleness. This can cause conductor breakage and stranding during subsequent winding or laying, resulting in production interruptions. Stress can also disrupt the stability of conductor morphology. Stranded conductors are prone to springback and twisting due to stress release, affecting the accuracy of subsequent insulation coating processes. During long-term use of finished cables, residual stress will slowly release with changes in ambient temperature, potentially causing conductor loosening, insulation cracking, shortening cable life, and even causing safety hazards such as short circuits.

DETAILED DESCRIPTION

[0054] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application is further described below in combination with specific embodiments.

[0055] As shown in Figure 1 , the cable manufacturing conductor surface treatment device provided by the application comprises a feeding mechanism, a stress relief part, a cooling mechanism, a heat relief mechanism, a storage mechanism, a flow guiding mechanism and a disturbance mechanism.

[0056] The feeding mechanism includes a platform 1, a support cylinder 5 and a guide plate 3. The outer wall of the guide plate 3 is provided with a through hole for the wire to pass through, and it is rotatably mounted on the platform 1 via the support cylinder 5. The support cylinder 5 is rotatably mounted on the platform 1.

[0057] During cable manufacturing, multiple conductors are first twisted together and then inserted into the insulation layer. A support plate is provided on one side of the platform 1. The support plate is fixedly connected to the support cylinder 5. A wire roller for winding the conductor is provided inside the support plate. The conductor on the wire roller passes through the through holes of the support plate, the support cylinder 5 and the guide plate 3 until multiple conductors converge. The rotation of multiple conductors is controlled to twist multiple conductors together into one.

[0058] The stress-relieving section is used to heat the wire. The stress-relieving section includes a stranding table 12 and a heating wire 2. The stranding table 12 is fixedly installed on the upper end face of the storage box 8. The stranding table 12 has a through hole for the wire to pass through. The axis of the through hole in the stranding table 12 coincides with the axis of the support cylinder 5. The stranding table 12 is provided with a compression block for compressing the wire (used to gather multiple wires together, not shown in the figure).

[0059] like Figure 3 As shown, the heating wire 2 is fixedly installed in the inner cavity of the stranding table 12. When the wire passes through the inner cavity of the stranding table 12, the heating wire 2 heats the stranding part of the wire, thereby relieving stress on the wire and improving the production quality of the stranding step.

[0060] The cooling mechanism is used to cool the heated wires. The cooling mechanism includes a cooling chamber 13, a spray pipe 17, and a return pipe 10.

[0061] The storage mechanism includes a storage tank 8 and a transfer tank 18 for storing coolant (the coolant is pure water, which is low in cost, readily available, and has a high specific heat capacity).

[0062] The cooling chamber 13 is fixedly installed on the upper surface of the storage box 8. The cooling chamber 13 is located on one side of the twisting table 12. The twisted and heated wires enter the inner cavity of the cooling chamber 13.

[0063] The spray pipe 17 is fixedly installed in the inner cavity of the cooling chamber 13, and the input end of the spray pipe 17 is connected to the output end of the control pump 14. The bottom of the spray pipe 17 is equipped with a nozzle that sprays coolant toward the wire, thereby cooling the heated wire. Rapid cooling can quickly lock the conductor's atomic stability state, avoid uneven cooling and the generation of new thermal stress, consolidate the stress relief effect of stranding, control the metallographic structure of the bare conductor, inhibit grain overgrowth to maintain conductivity and ductility, shorten high-temperature exposure, and reduce oxidation to maintain surface smoothness.

[0064] The inner cavity of the cooling chamber 13 is connected to the inner cavity of the storage tank 8 through the return pipe 10. The coolant after spraying flows back to the inner cavity of the storage tank 8 through the return pipe 10 to facilitate the recycling of the coolant.

[0065] The heat-dissipating mechanism comprises a heat exchange plate 25 fixedly installed on the inner wall of the storage tank 8 and an exhaust pipe 6 arranged on one side of the heat exchange plate 25. In this embodiment, the heat exchange plate 25 is a common copper plate for absorbing the heat of the cooling liquid in the inner cavity of the storage tank 8. The exhaust pipe 6 is internally provided with an axial flow fan for increasing the air flow speed on the surface of the heat exchange plate 25, thereby increasing the heat dissipation efficiency of the heat exchange plate 25, and cooling the cooling liquid in the inner cavity of the storage tank 8 for recycling.

[0066] As shown in Figure 4 and Figure 5 , the flow guiding mechanism comprises a control pump 14, a feeding pipe 33 and a filter cover 35. The transfer tank 18 is connected with the storage tank 8 through the feeding pipe 33. The inside of the feeding pipe 33 is provided with a one-way valve. The inner cavity of the transfer tank 18 is provided with a semiconductor refrigeration sheet. The hot end of the semiconductor refrigeration sheet is located on the outer wall of the transfer tank 18, and the cold end is located in the inner cavity of the transfer tank 18.

[0067] As shown in Figure 7 , the cooling liquid in the transfer tank 18 is discharged through the control pump 14. The filter cover 35 is slidingly arranged at one end of the feeding pipe 33. The filter cover 35 is used to filter the impurities of the cooling liquid entering the inside of the feeding pipe 33.

[0068] When the control pump 14 works, the cooling liquid in the inner cavity of the transfer tank 18 is extracted and then delivered to the spray pipe 17 and finally discharged by the spray head to cool the heated wire. After the cooling liquid enters the inner cavity of the storage tank 8 through the return pipe 10, it is preliminarily cooled by the heat exchange plate 25, and then enters the inner cavity of the transfer tank 18 to be further cooled by the semiconductor refrigeration sheet, and then is delivered to the spray pipe 17 by the control pump 14 to complete the cooling.

[0069] As shown in Figure 6 , the disturbance mechanism comprises a mounting disc 22 and a spoiler 24. The mounting disc 22 is rotationally arranged in the inner cavity of the storage tank 8. The spoiler 24 is fixedly installed on the radial outer wall of the mounting disc 22. When the heat exchange plate 25 absorbs the heat of the cooling liquid, the spoiler 24 is rotated to disturb the flow of the cooling liquid in the inner cavity of the storage tank 8.

[0070] Thus, the limitation of natural convection of the cooling liquid is broken, the cooling liquid in the storage tank 8 fully contacts with the heat exchange plate 25, the efficiency of the heat exchange plate 25 absorbing the heat of the cooling liquid is improved, the cooling of the cooling liquid is accelerated, and at the same time, the local high temperature area of the cooling liquid in the storage tank 8 due to poor flow is avoided, the temperature of the cooling liquid is uniform, the temperature of the cooling liquid used for wire cooling is stable, the deposition of impurities on the surface of the heat exchange plate 25 is reduced through fluid scouring, the heat conduction efficiency of the heat exchange plate 25 is slowed down, the equipment maintenance period is prolonged, and finally the stable operation of the entire cooling liquid circulation system is ensured, and continuous and efficient low-temperature cooling liquid is provided for the wire cooling link.

[0071] The filter cover 35 rotates synchronously with the mounting disc 22, when the mounting disc 22 rotates, the filter cover 35 slides along its own axis while rotating along its own axis, so that when the cooling liquid is extracted from the delivery pipe 33, the pressure balance on the surface of the filter cover 35 is broken, thereby preventing the impurities in the cooling liquid from concentrating on the same position of the outer wall of the filter cover 35, and at the same time, the movable filter cover 35 can reduce the adhesion of impurities, and when the mounting disc 22 rotates, the cooling liquid flow is disturbed, which can to some extent peel off the adhesions on the surface of the filter cover 35, thereby maintaining the cooling efficiency of the wires.

[0072] As a preferred embodiment of the present application, as shown in Figure 2 The outer wall of the storage box 8 is fixedly provided with the mounting cover 7, the side wall of the mounting cover 7 is provided with an exhaust hole, one end of the exhaust pipe 6 is fixedly connected with the outer wall of the mounting cover 7, and one end of the heat exchange plate 25 penetrates the storage box 8 and extends into the inner cavity of the mounting cover 7, so as to suck the air on the surface of the heat exchange plate 25.

[0073] The upper end surface of the support table 1 is fixedly provided with the air delivery pipe 15, one end of the air delivery pipe 15 is connected with the exhaust pipe 6, and the other end extends into the inner cavity of the support cylinder 5, so that the exhaust pipe 6 delivers hot air into the inner cavity of the support cylinder 5, thereby preheating the wires passing through the inside of the support cylinder 5, and utilizing the waste heat in the cooling process of the cooling liquid for preheating the wires.

[0074] The upper end surface of the support table 1 is fixedly provided with the control motor 4, the control motor 4 controls the rotation of the support cylinder 5 through the control motor 4, and the control motor 4 controls the rotation of the support cylinder 5 through the cooperation of the belt and the belt pulley, so as to realize the stranding of the wires.

[0076] The mounting disc 22 is fixedly installed on the outer wall of the crankshaft 31, and the axis of the mounting disc 22 is real-time coincident with the axis of the output shaft of the driving motor 9 when the mounting disc 22 rotates, and the rotation of the mounting disc 22 drives the rotation of the spoiler 24 on the outer wall of the mounting disc 22, thereby realizing the disturbance of the inner cavity of the storage box 8.

[0077] As a preferred embodiment of the present application, the inner cavity of the storage box 8 is fixedly provided with the control cylinder 27, the inner cavity of the control cylinder 27 is elastically provided with the control plug 28, the outer wall of the control plug 28 is provided with a spring, one end of the spring is connected with the inner cavity of the control cylinder 27, and the spring is used to drive the control plug 28 to reset after the control plug 28 slides.

[0079] The control cylinder 27 is provided with a plurality of control cylinders, and when the control plug 28 reciprocates, the crankshaft 31 is driven to rotate, and the mounting disc 22 is controlled to rotate.

[0080] The outer wall of the control cylinder 27 is fixedly provided with an air inlet pipe 26 and an air outlet pipe 20, and the inner cavities of the air inlet pipe 26 and the air outlet pipe 20 are provided with electromagnetic valves.

[0081] The other end of the air outlet pipe 20 is in communication with the outside of the storage tank 8, and the air inlet pipe 26 is in communication with the inner cavity of the storage tank 8. With the circulation of the coolant, the temperature of the coolant in the inner cavity of the storage tank 8 gradually rises, causing the air pressure in the inner cavity of the storage tank 8 to rise.

[0082] When the air pressure in the inner cavity of the storage tank 8 rises, the electromagnetic valve in the air inlet pipe 26 is turned on, and the gas in the storage tank 8 enters the inner cavity of the control cylinder 27 through the air inlet pipe 26. At this time, the control plug 28 slides downward, and then the electromagnetic valve in the air inlet pipe 26 is closed, the electromagnetic valve in the air outlet pipe 20 is opened, the spring pushes the control plug 28 to reset, the gas in the control cylinder 27 is discharged through the air outlet pipe 20, and the reciprocating sliding of the control plug 28 is realized, which is used to control the rotation of the crankshaft 31.

[0083] The bottom of the control cylinder 27 is fixedly provided with a pressure relief pipe in communication with the outside of the storage tank 8, and the inner cavity of the control cylinder 27 is divided into two cavities by the control plug 28, so that the air pressure on one side of the control cylinder 27 is balanced when the control plug 28 reciprocates.

[0084] In use, initially, the inner cavity of the storage tank 8 has a low coolant temperature, at this time, the crankshaft 31 is driven to rotate by the driving motor 9, and as the coolant temperature in the storage tank 8 increases, the driving motor 9 is turned off, and the rotation of the crankshaft 31 is controlled by the air pressure (at this time, the output shaft of the driving motor 9 is connected with the crankshaft 31 through a one-way bearing, which is used to reduce the resistance of the rotation of the crankshaft 31 when the crankshaft 31 is driven to rotate by the air pressure), and at the same time, the pressure relief of the inner cavity of the storage tank 8 is realized, which reduces the energy consumption and prevents the air pressure in the inner cavity of the storage tank 8 from being too high.

[0085] As shown in Figure 8 and 9 The inner wall of the storage tank 8 is fixedly provided with a bellows 34, and one end of a filter cover 35 is connected with the bellows 34 through a sealing bearing.

One end of the mounting bracket 40 is fixedly provided with an arc-shaped plate 41. The arc-shaped plate 41 is made of elastic material and is located between two adjacent heat exchange plates 25. The sliding of the mounting bracket 40 drives the arc-shaped plate 41 to slide, thereby disturbing the flow of the cooling liquid between the two heat exchange plates 25, preventing the cooling liquid from being static between the heat exchange plates 25, and further improving the turbulence efficiency of the cooling liquid, thereby maintaining the uniform temperature of the cooling liquid in the inner cavity of the storage box 8.

[0090] The side wall of the heat exchange plate 25 is fixedly provided with a pressing ball 16. When the arc-shaped plate 41 passes over the pressing ball 16, the arc-shaped plate 41 is reset. The side wall hits the side wall of the heat exchange plate 25, causing the heat exchange plate 25 to vibrate, thereby further preventing impurities in the cooling liquid from adhering to the outer wall of the heat exchange plate 25, and maintaining the cooling efficiency of the heat exchange plate 25 for the cooling liquid.

[0091] The outer wall of the crankshaft 31 is fixedly provided with a sector gear 32. The inner wall of the storage box 8 is elastically provided with a guide bracket 38 which is connected with the inner wall of the storage box 8 through a spring.

[0092] The outer wall of the guide bracket 38 is fixedly provided with a toothed plate 39 which is engaged with the sector gear 32. The other end of the toothed plate 39 is fixedly connected with the mounting bracket 40. The axis of the sector gear 32 coincides with the axis of the mounting disc 22. When the sector gear 32 is engaged with the toothed plate 39, the sector gear 32 is rotated to drive the toothed plate 39 to slide, thereby controlling the sliding of the arc-shaped plate 41. After the sector gear 32 is separated from the toothed plate 39, the elastic force of the spring resets the mounting bracket 40 and the arc-shaped plate 41, thereby controlling the reciprocating sliding of the arc-shaped plate 41.
