Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of litz wire processing, in particular to a litz wire processing technology and a square pressing machine. BACKGROUND

[0002] Litz wire is a conductor composed of multiple single insulated wires twisted or braided together, used to reduce losses caused by skin effect and proximity effect under high-frequency operation. This structure allows electromagnetic fields to be distributed more evenly, thereby reducing the impact of skin effect and proximity effect on current distribution.

[0003] In the litz wire processing process, square pressing is a key step, its main purpose is to convert the circular cross-section of twisted wire into a square cross-section. Pressing the twisted wire with a circular cross-section into a square cross-section can significantly improve space utilization. In the same volume, the twisted wire with a square cross-section can accommodate more conductive wires, thereby improving the overall conductivity of the litz wire. Therefore, square pressing plays an important role in the litz wire processing process, including improving space utilization, enhancing mechanical properties, optimizing electromagnetic properties, facilitating subsequent processing, and improving heat treatment effect. Through square pressing, the overall performance and quality of the litz wire can be significantly improved, making it more suitable for various complex application scenarios.

[0004] In Chinese patent CN117877811A, a processing and preparation method for rigid square litz wire is provided. The application heats and shapes the wire into a heat treatment array type forming device, causing self-adhesion between the enameled wires, and forming a whole litz wire to produce rigidity. This invention makes the wire have a certain rigidity, making it easier to form a shaped coil and ensuring the performance of the product. However, first, during the square pressing process, dust and impurities may adhere to the surface of the twisted wire. If there is no air blowing dust removal structure, these dust and impurities may be pressed into the twisted wire during the square pressing process, causing the surface of the twisted wire after square pressing to be uneven, affecting the quality of the subsequent process. Dust and impurities may enter the mechanical parts of the square pressing machine during the square pressing process, increasing wear and tear and reducing the service life of the square pressing machine. The presence of dust and impurities may affect the subsequent insulation coating and heat treatment processes, resulting in a decrease in the adhesion of the insulation layer and uneven heat treatment, ultimately affecting the overall performance of the litz wire. Second, the above document does not mention the horizontal movement function of the square pressing machine, which means that the square pressing machine cannot be flexibly adjusted according to the diameter and shape of the twisted wire. When processing twisted wires of different specifications, it is necessary to frequently replace the square pressing die or make complex equipment adjustments, increasing the complexity and time cost of the operation.
