Description

Technical Field

[0001] The present invention belongs to the technical field of electromagnetic wires, and specifically relates to a production process of high-toughness copper-clad aluminum electromagnetic wires. Background Art

[0002] Electromagnetic wires are insulated wires used to manufacture coils or windings in electrical products. Also known as winding wires, electromagnetic wires must meet various usage and manufacturing process requirements. The former includes their shape, specifications, the ability to work at high temperatures for short and long periods, and withstand strong vibrations and centrifugal forces at high speeds in certain situations, withstand corona and breakdown under high voltages, and resist chemical corrosion in special atmospheres, etc. The latter includes requirements such as being stretched, bent, and worn during winding and wire insertion, as well as swelling and erosion during impregnation and drying processes.

[0003] In the prior art, during the frequent movement or bending of copper-clad aluminum electromagnetic wires, they are prone to tearing, and the internal wires are prone to bending and dislocation. When the bending angle is relatively large, the internal wires are even prone to core breakage, making them unusable and having a high repair difficulty. Existing electromagnetic wires have an insulating layer coated on the conductor. Usually, due to the unreasonable structure of the insulating layer, the insulating layer of copper-clad aluminum electromagnetic wires has poor sealing performance, is prone to corrosion when encountering water, shortens the service life of the electromagnetic wires, and increases costs. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides a production process of high-toughness copper-clad aluminum electromagnetic wires, which has the advantages of high toughness and good sealing performance of copper-clad aluminum electromagnetic wires.

[0005] To achieve the above object, the present invention provides the following technical solution: A production process of high-toughness copper-clad aluminum electromagnetic wires, including a limiting block and an insulating layer. The specific steps of this production process are as follows: After the copper-clad aluminum electromagnetic wire is produced, it is wound. When the copper-clad aluminum electromagnetic wire is wound, the copper-clad aluminum electromagnetic wire will be bent and wound onto the winding wheel. At this time, the limiting block inside the copper-clad aluminum electromagnetic wire will be squeezed and bent, squeezing the buffer block inside the limiting block, and the buffer block will buffer the electromagnetic wire. The toughness of the electromagnetic wire is increased through the quadrilateral structure of the buffer block, and the limiting column will limit it. At the same time, the toughness of the electromagnetic wire is increased through the buffer layer. When the buffer layer is bent, the buffer pad inside the buffer layer will be squeezed;

[0006] When the copper-clad aluminum electromagnetic wire is needed, the copper-clad aluminum electromagnetic wire is taken down. At this time, the buffer block will reset and drive the electromagnetic wire to extend and stretch. When using the electromagnetic wire, the electromagnetic wire is sealed by the inner waterproof layer and the outer waterproof layer, effectively preventing the magnetic core of the electromagnetic wire from being eroded when encountering water. At the same time, the performance of the copper-clad aluminum electromagnetic wire is increased through the insulating layer.

[0007] In the above technical solution, preferably, four clamping grooves are annularly and equally angularly formed around the limiting block, and an aluminum core is movably clamped inside the four clamping grooves. A limiting column is fixedly installed in the middle of the limiting block, and buffer blocks are fixedly installed on the surface of the limiting column in an annular and equally angular manner. A filling layer is fixedly sleeved outside the limiting block, a buffer layer is fixedly sleeved outside the filling layer, and buffer pads are fixedly installed in the buffer layer in an annular and equally angular manner.

[0008] In the above technical solution, preferably, a copper core is fixedly sleeved outside the aluminum core, an insulating layer is fixedly sleeved outside the copper core, an inner waterproof layer is fixedly sleeved outside the insulating layer, an outer waterproof layer is fixedly sleeved outside the buffer layer, and an outer surface layer is fixedly sleeved outside the outer waterproof layer.

[0009] In the above technical solution, preferably, the buffer block is composed of multiple groups of hollow quadrilaterals, the limiting column penetrates through the middle of the buffer block, and both the limiting block and the buffer block are made of rubber material.

[0010] In the above technical solution, preferably, the buffer pad is in the shape of a parallelogram, and triangular holes are formed at the left and right ends of the buffer pad. The buffer layer is made of rubber material.

[0011] In the above technical solution, preferably, both the inner waterproof layer and the outer surface layer are made of rubber material, the outer waterproof layer is made of polyethylene material, and the outer waterproof layer is wound around the outside of the buffer layer.

[0012] In the above technical solution, preferably, the insulating layer is made of polyimide material, and the filling layer is made of silica gel material.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. By providing buffer blocks, limiting blocks, and limiting columns, etc., the present invention achieves the purpose of high toughness of copper-clad aluminum magnet wire. When the copper-clad aluminum magnet wire is wound, the copper-clad aluminum magnet wire will be bent and wound around the winding wheel. At this time, the limiting block inside the copper-clad aluminum magnet wire will be squeezed and bent, squeezing the buffer block inside the limiting block. The buffer block will buffer the magnet wire. The quadrilateral structure of the buffer block increases the toughness of the magnet wire, and the limiting column will limit it. At the same time, the toughness of the magnet wire is increased through the buffer layer. When the buffer layer is bent, the buffer pads inside the buffer layer will be squeezed, reducing the bending angle of the copper-clad aluminum magnet wire and increasing the toughness of the magnet wire, achieving the effect of high toughness of the copper-clad aluminum magnet wire.

[0015] 2. The present invention achieves the purpose of good sealing performance of the copper-clad aluminum electromagnetic wire by providing an insulating layer, an inner waterproof layer, an outer waterproof layer, etc. When using the electromagnetic wire, the inner waterproof layer and the outer waterproof layer are used to seal the electromagnetic wire, effectively preventing the magnetic core from being eroded by water when the electromagnetic wire is in use. At the same time, the performance of the copper-clad aluminum electromagnetic wire is enhanced through the insulating layer, achieving the effect of good sealing performance of the copper-clad aluminum electromagnetic wire.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Such as Figures 1 to 6As shown in the figure, the present invention provides a production process for a high-toughness copper-clad aluminum electromagnetic wire, including a limiting block 1 and an insulating layer 4. The specific steps of this production process are as follows: After the copper-clad aluminum electromagnetic wire is produced, it is wound up. When the copper-clad aluminum electromagnetic wire is wound, the copper-clad aluminum electromagnetic wire will be bent and wound around the winding wheel. At this time, the limiting block 1 inside the electromagnetic wire will be squeezed and bent, squeezing the buffer block 10 inside the limiting block 1. The buffer block 10 will buffer the electromagnetic wire, and the toughness of the electromagnetic wire is increased through the quadrilateral structure of the buffer block 10. The limiting column 11 will limit it. At the same time, the toughness of the electromagnetic wire is increased through the buffer layer 7. When the buffer layer 7 is bent, the buffer pad 13 inside the buffer layer 7 will be squeezed;

[0025] When the copper-clad aluminum electromagnetic wire is needed, the copper-clad aluminum electromagnetic wire is taken down. At this time, the buffer block 10 will reset and drive the electromagnetic wire to extend and stretch. When using the electromagnetic wire, the inner waterproof layer 5 and the outer waterproof layer 8 are used to seal the electromagnetic wire, effectively preventing the magnetic core of the electromagnetic wire from being eroded when encountering water during use. At the same time, the performance of the copper-clad aluminum electromagnetic wire is increased through the insulating layer 4.

[0026] As Figure 1 , 2 As shown in Figures 1, 2, and 3, it includes a limiting block 1. Four clamping grooves 12 are annularly and equally angularly opened around the limiting block 1. An aluminum core 2 is movably clamped inside the four clamping grooves 12. A limiting column 11 is fixedly installed in the middle of the limiting block 1. Buffer blocks 10 are fixedly installed on the surface of the limiting column 11 in an annular and equally angular manner. A filling layer 6 is fixedly sleeved outside the limiting block 1. A buffer layer 7 is fixedly sleeved outside the filling layer 6. Buffer pads 13 are fixedly installed in the buffer layer 7 in an annular and equally angular manner;

[0027] After the copper-clad aluminum electromagnetic wire is produced, it needs to be wound up. At this time, the copper-clad aluminum electromagnetic wire will be wound onto the surface of the winding wheel. The copper-clad aluminum electromagnetic wire will be bent, the limiting block 1 will be bent, and the buffer block 10 inside the limiting block 1 will be squeezed and deformed. The buffer block 10 buffers the copper-clad aluminum electromagnetic wire to increase the toughness of the copper-clad aluminum electromagnetic wire.

[0028] As Figure 1 , 2 As shown in Figures 1, 2, and 3, a copper core 3 is fixedly sleeved outside the aluminum core 2. An insulating layer 4 is fixedly sleeved outside the copper core 3. An inner waterproof layer 5 is fixedly sleeved outside the insulating layer 4. An outer waterproof layer 8 is fixedly sleeved outside the buffer layer 7. An outer surface layer 9 is fixedly sleeved outside the outer waterproof layer 8;

[0029] Adopting the above scheme: The outer waterproof layer 8 and the outer surface layer 9 protect the outside of the copper-clad aluminum electromagnetic wire. When using the copper-clad aluminum electromagnetic wire, the insulating layer 4 and the inner waterproof layer 5 seal the magnetic core of the electromagnetic wire to prevent the electromagnetic wire from being corroded by water during use.

[0030] AsFigure 3 , 4 As shown in 4 , the buffer block 10 is composed of multiple groups of hollow quadrilaterals. The limit post 11 penetrates through the middle of the buffer block 10. Both the limit block 1 and the buffer block 10 are made of rubber material.

[0031] Adopting the above scheme: When the copper-clad aluminum electromagnetic wire needs to be bent, the limit block 1 will be bent. By bending the limit block 1, the buffer block 10 inside the limit block 1 will be extruded. The buffer block 10 will be compressed, and the limit post 11 will limit the buffer block 10. By extruding the buffer block 10, the toughness of the electromagnetic wire is increased.

[0032] As Figure 3 , 5 As shown in 5 , the buffer pad 13 is in the shape of a parallelogram, and triangular holes are provided at both the left and right ends of the buffer pad. The buffer layer 7 is made of rubber material.

[0033] Adopting the above scheme: When using or winding the copper-clad aluminum electromagnetic wire, the copper-clad aluminum electromagnetic wire will be bent. By bending the buffer layer 7, the copper-clad aluminum electromagnetic wire is buffered and protected. When the buffer layer 7 is bent, the buffer pad 13 inside the buffer layer 7 will be extruded and compressed, reducing the bending angle of the internal electromagnetic wire. At the same time, the toughness of the copper-clad aluminum electromagnetic wire is increased by the buffer pad 13.

[0034] As Figure 1 , 2 As shown in 2 and 5, both the inner waterproof layer 5 and the outer surface layer 9 are made of rubber material, and the outer waterproof layer 8 is made of polyethylene material. The outer waterproof layer 8 is wound around the outside of the buffer layer 7.

[0035] Adopting the above scheme: The inner waterproof layer 5 and the outer waterproof layer 8 are used to seal and protect the internal copper-clad aluminum electromagnetic wire, preventing the internal copper-clad aluminum wire from being eroded by water during use, resulting in a reduction in the service life of the copper-clad aluminum electromagnetic wire.

[0036] As Figure 1 , 2 As shown in 2 , the insulating layer 4 is made of polyimide material, and the filling layer 6 is made of silica gel material.

[0037] Adopting the above scheme: The toughness of the outside of the copper-clad aluminum electromagnetic wire is increased by the insulating layer 4, preventing the copper-clad aluminum electromagnetic wire from being exposed. At the same time, the copper-clad aluminum electromagnetic wires around the limit block 1 are made more stable by the filling layer 6.
