Description

Technical Field

[0001] The present application relates to the technical field of insulating film manufacturing of high-current aluminum alloy single-core wires, and in particular to an insulating film manufacturing device and a process for manufacturing a high-current aluminum alloy single-core wire. Background Art

[0002] With the rapid development of electric vehicles and energy storage equipment markets, the demand for high voltage and high current transmission is increasing. In this context, high current aluminum alloy single core wires are widely used in these fields due to their excellent conductivity and lightweight characteristics.

[0003] However, in order to meet the requirements of safety and reliability, such wires need to have a high-quality insulation layer. The common insulation film production methods on the market currently mainly include resin spraying and dipping, but these traditional methods are often difficult to achieve ideal insulation effects when facing high-voltage environments.

[0004] Among them, the resin spraying method uses a spray gun to evenly spray liquid resin onto the aluminum wire to form a protective film. However, due to the strong fluidity of the liquid resin, it is easy to sag under the action of gravity, resulting in uneven coating thickness and unable to meet the insulation requirements under high-voltage environments. The resin dipping method is to completely immerse the aluminum wire in liquid resin, then take it out to dry and solidify. However, it also has the problem of sagging, especially during long-term immersion, the resin may gather in certain parts, causing local over-thickness or over-thinness.

[0005] Therefore, whether it is resin spraying or dipping, there are problems such as uneven coating thickness and easy sagging. These problems will lead to unstable quality of the insulating film in practical applications, thus affecting the performance and safety of the final product. In addition, the existing methods are prone to cracking of the insulating film during subsequent processing (such as bending), further reducing the reliability and service life of the product.

[0006] Therefore, in order to solve the above-mentioned related technical problems, an insulating film manufacturing device and a process thereof for a large current aluminum alloy single-core wire are proposed. Summary of the invention

[0024] 3. Compared with the prior art, the insulating film manufacturing equipment and process of the large current aluminum alloy single-core wire realize the continuity of the spraying work through intermittent pushing action. The push block ring is a one-way diaphragm ring structure. Its shape will not change when it moves in the direction of the drying box. Since it contacts one end of the aluminum alloy conductive rod, it can push the aluminum alloy conductive rod to move. When it moves away from the drying box, it will deform to the moving side to form a hole with a larger diameter than before. Since the position of the aluminum alloy conductive rod is limited by the shaft grooves on multiple groups of limiting shafts, the push block ring will not contact the aluminum alloy conductive rod, thereby not changing the position of the aluminum alloy conductive rod. The telescopic push block is pushed to move by the electric telescopic rod, and the telescopic push block drives the aluminum alloy conductive rod inside it to move through the telescopic push block during the movement.
