[0002] Aluminum clad steel core aluminum stranded wire is a composite conductive wire that combines a high-strength steel wire core with a pure aluminum or aluminum alloy layer, and is widely used in power transmission lines. This wire uses the mechanical strength provided by the steel core and the good electrical conductivity of the aluminum layer to effectively balance the needs of weight and conductive efficiency. Its production process includes straightening and cleaning of the steel wire, hot extrusion coating of aluminum, and necessary anti-corrosion treatment to ensure corrosion resistance and long-term environmental adaptability. Aluminum clad steel core aluminum stranded wire is widely used in high-voltage and ultra-high-voltage transmission lines due to its excellent physical and electrical properties, especially in areas with large spans or harsh environments.

[0033] S101: receiving the tension value tens1 obtained by the initial tension sensor at time t and the tension value tens2 obtained by the final tension sensor at time t,

[0034] S102: receiving the thickness value of the aluminum-clad steel wire wound on the primary winding device monitored by the primary photoelectric sensor at time t, and the three thickness values ​​obtained by the primary photoelectric sensor at the moment before t, at time t, and at the moment after t are represented as Ha1, Ha2, and Ha3 respectively.

[0050] The parameter values ​​of k and h are initially set based on historical tests, and k and h are gradually adjusted based on a large number of repeated experimental trainings to minimize the diameter length difference and tension difference between the aluminum-clad steel wire and the aluminum-clad steel core anti-corrosion high-conductivity aluminum stranded wire, until k and h achieve a satisfactory adjustment effect and the high efficiency and stability of the manufacturing system of the present invention, and the final k and h are obtained.

[0051] In this embodiment, those skilled in the art can refer to the above value examples and make adjustments according to actual conditions. In short, the specific value ranges and trends of the above β, γ, RF1, RF2, R1, R2, k, and h will be determined by the designer or operator of the production system according to actual processing requirements and system response, and will not be repeated here.

[0052] The present invention monitors and adjusts the winding speeds of the primary winding device and the final winding device through a control unit to effectively control the tension of the aluminum clad steel wire and the aluminum clad steel core corrosion-resistant high-conductivity aluminum stranded wire during the production process, thereby avoiding the uneven thickness of the product caused by uneven tension that may lead to material relaxation or excessive stretching, affecting the stranding quality and the mechanical properties of the wire, thereby improving the overall consistency and reliability of the production system.

[0053] Embodiment 3: Combining with Figure 1 and attached Figure 2 In addition to the contents of the above embodiments, the coating module includes an oil supply unit for conveying anti-corrosion oil to the aluminum-clad steel wire, a coating unit for evenly coating the anti-corrosion oil on the aluminum-clad steel wire, and a drying unit for drying and curing the anti-corrosion oil on the aluminum-clad steel wire to obtain an anti-corrosion layer.

[0054] The oil inlet unit comprises a storage tank for storing the anti-corrosion oil, a liquid outlet pipe connected to the storage tank, a liquid pump driving the anti-corrosion oil in the storage tank to flow out of the liquid outlet pipe, a feed nozzle abutting against the outer wall of the aluminum-clad steel wire, and a connecting piece connecting the liquid outlet pipe with the feed nozzle.

[0055] The feed nozzle is flat, and the discharge end of the feed nozzle is arranged near the top of the aluminum-clad steel wire. Driven by the liquid pump, the anti-corrosion oil flows from the feed nozzle to the aluminum-clad steel wire at a preset flow rate.

[0056] The coating unit comprises an outer shell in the shape of a ring, an inner shell in the shape of a ring and coaxially sleeved in the outer shell, a bearing ring with an outer ring fixed to the inner wall of the outer shell and an inner ring fixed to the outer wall of the inner shell, a support frame for supporting and fixing the bottom shell wall of the outer shell, two fixed blocks respectively fixed to the inner shell, a driving mechanism for driving the fixed blocks to move relative to the sleeve shell, and two smear brushes respectively fixed to different fixed blocks.

[0057] The left and right sides of the inner shell extend and protrude from the left and right sides of the outer shell respectively, the edges of the ring opening on both sides of the inner shell are the left ring opening edge and the right ring opening edge respectively, the driving mechanism comprises an outer gear ring sleeved on the outer wall of the ring near the left ring opening edge of the inner shell, a driving gear meshing with the outer gear ring and a driving motor for driving the driving gear to rotate the shaft.

[0058] The two fixing blocks are symmetrically arranged on the right ring edge of the inner shell, and the two smear brushes are fixed on different fixing blocks respectively.

[0059] Through the driving operation of the driving motor, the inner shell is driven to rotate relative to the outer shell, and then the fixed block and the coating brush are synchronously driven to rotate along the axis of the inner shell, so that the coating brush can evenly spread the anti-corrosion oil on the surface of the aluminum-clad steel wire.

[0060] The drying unit comprises a cylinder coaxially sleeved on the outside of the aluminum-clad steel wire, air outlets sequentially arranged on the cylinder wall of the cylinder, a hot air drying fan connected to each air outlet through an air guide pipe, and a temperature control subunit for controlling the air outlet speed of each air outlet.

[0061] Along the conveying direction of the aluminum-clad steel core, the temperature control subunit gradually increases the wind speed setting of each air outlet. The increasing wind speed setting allows the anti-corrosion oil coating to start the curing process slowly when it is just applied, and gradually increases the drying intensity as the aluminum-clad steel core moves forward. This progressive drying process helps prevent cracks or uneven curing caused by too fast drying of the coating, and improves the consistency and quality of the final product.

[0062] The anti-corrosion oil flows evenly onto the moving aluminum clad steel wire through the feed nozzle. The fixed coating brush on the inner shell rotates with the inner shell to evenly coat the anti-corrosion oil on the surface of the aluminum clad steel wire. After further drying by the drying unit, the anti-corrosion oil is completely solidified to form a solid anti-corrosion layer, providing protection for the aluminum clad steel wire.

[0063] The coating module of the present invention realizes efficient, uniform coating and rapid drying of aluminum-clad steel wire by integrating an oil inlet unit, a film coating unit and a drying unit, thereby ensuring the uniformity and curing quality of the anti-corrosion oil layer. This process not only improves the anti-corrosion performance and durability of the aluminum-clad steel wire, but also improves production efficiency and reduces costs by precisely controlling coating and drying parameters.

That is, the methods, systems and devices discussed above are examples. Various configurations may appropriately omit, replace or add various processes or components. For example, in alternative configurations, the method may be performed in an order different from that described, and / or various components may be added, omitted and / or combined. Moreover, the features described with respect to certain configurations may be combined in various other configurations, such as different aspects and elements of the configuration may be combined in a similar manner. In addition, as technology develops, the elements therein may be updated, i.e., many elements are examples and do not limit the scope of the present disclosure or claims. And it should be understood that after reading the contents of the record of the present invention, the technician may make various changes or modifications to the present invention, and these equivalent changes and modifications also fall within the scope defined by the claims of the present invention.
