[0003] When pressing high-strength flat copper wire, the diameter of the copper wire body is required to be larger. When the diameter of the copper wire body is larger, it is undoubtedly necessary to increase the pressing force of mechanisms such as pressing rollers, which not only consumes energy, but also the copper wire body with a larger diameter will be deformed to a large extent when flattened, which will easily cause problems such as cracking, position displacement or breakage.

[0004] Therefore, it is necessary to propose a high-strength flat copper wire to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a high-strength flat copper wire to solve the problem that when the diameter of the copper wire body is large, it is undoubtedly necessary to increase the pressing force of mechanisms such as pressing rollers, which not only consumes energy, but also the copper wire body with a large diameter is easily cracked, displaced or broken when deformed to a large extent when flattened.

[0006] To achieve the above object, the present invention provides the following technical solution: a high-strength flat copper wire, comprising a flat copper wire, wherein the flat copper wire comprises at least two copper wires and a copper body structure formed after solidification of copper liquid; At least two copper wires are intertwined and braided to form a copper wire body; The copper body structure is filled outside the copper wire body and between the copper wire body to form a flat copper wire to be formed.

[0007] Preferably, the flat copper wire comprises the following preparation method: Step 1: Prepare at least two copper wires and copper liquid; The second step: two copper wires are intertwined and braided to form a chain-like copper wire body, and then the copper wire body is contained in a mold, and the copper wire body is pressed in the mold. While pressing, molten copper is poured around the copper wire body. The molten copper is fully mixed with the copper wire body, and pressed again to form a flat copper wire to be formed. The flat copper wire to be formed is formed after the flat copper wire to be formed is completely cooled.

[0008] Preferably, the pressing device of the flat copper wire comprises a mold, and the mold is used to accommodate a copper wire body formed by braiding at least two copper wires; A first pressing roller, which is rotatably disposed in the mold and is used for preliminarily pressing the copper wire body; The second pressing roller is rotatably arranged in the mold and is used for secondary pressing of the copper wire body.

[0009] Preferably, the mold is a concave-shaped groove body.

[0010] Preferably, a plurality of thorns are evenly and fixedly arranged on the outer ring of the first pressing roller.

[0011] Preferably, a plurality of the second pressing rollers are provided, and the diameters of the plurality of second pressing rollers gradually increase from a position close to the first pressing roller to a position far away from the first pressing roller.

DETAILED DESCRIPTION

[0027] In embodiment 1, the present invention provides Fig. 9 A high-strength flat copper wire is shown in the figure. The high-strength flat copper wire includes a flat copper wire 10. The flat copper wire 10 is formed by braiding, casting and pressing processes. First, at least two copper wires 6 and copper liquid are prepared.

[0028] like Figure 4As shown in the figure, in the present invention, two copper wires 6 are taken as an example, the two copper wires 6 are intertwined and braided to form a chain-like copper wire body, and then a mold is used to accommodate the copper wire body, and a mechanism similar to a pressing roller is used in the mold to press the copper wire body. While pressing, copper liquid is cast around the copper wire body, and the copper liquid is fully mixed with the copper wire body. After being pressed by a mechanism similar to a pressing roller, a copper wire body is formed as shown in the figure. Figure 3 The flat copper wire 601 to be formed is shown in the figure; the production process of the flat copper wire 601 to be formed is superior to the prior art and ensures the basic strength of the flat copper wire 601 to be formed.

[0029] In the prior art, when flat copper wire is pressed, a mechanism such as a pressing roller is usually used to directly flatten the copper wire, and there are both cold pressing methods and hot pressing methods.

[0030] When pressing high-strength flat copper wire, the diameter of the copper wire body is required to be larger. When the diameter of the copper wire body is larger, it is undoubtedly necessary to increase the pressing force of the pressing roller and other mechanisms, which not only consumes energy, but also the copper wire body with a larger diameter will be easily deformed to a large extent when flattened, which will easily cause problems such as cracking, position displacement or breakage.

[0031] Therefore, the present invention combines weaving, casting and pressing processes, and uses two copper wires 6 with smaller diameters to be intertwined and weaved to form a copper wire body. Compared with a copper wire body with a larger diameter, it is easier to press and deform, and is less likely to crack, shift or break.

[0032] When the copper wire body formed by pressing two copper wires 6 is cast, the copper liquid can be fully filled in the gap of the copper wire body, so that the copper wire body and the copper liquid are mixed to form an integrated structure. When the flat copper wire 601 to be formed is pressed and formed, the copper liquid that has just cooled and solidified is fully combined between the two copper wires 6, so that the two copper wires 6 and the copper body formed by the condensation of the copper liquid are interlocked and not easy to be delaminated, the overall strength is high, and the adhesion of the flat copper wire is improved.

[0033] Correspondingly, the flat copper wire 601 to be formed can also be formed by combining multiple copper wires 6 with copper liquid, which will not be described in detail here.

[0034] In embodiment 1, a pressing device for pressing the flat copper wire 601 to be formed is also provided, such as Figures 1 to 3As shown in the figure, the pressing equipment includes a mold 1, a first pressing roller 2 and a second pressing roller 3; the mold 1 is usually a concave trough body for accommodating the copper wire 6 and the copper liquid, and the first pressing roller 2 and the second pressing roller 3 are both rotatably arranged in the concave trough body of the mold 1, and the first pressing roller 2 and the second pressing roller 3 are equipped with a power mechanism; when the power mechanism is started, the first pressing roller 2 and the second pressing roller 3 rotate, and when the first pressing roller 2 rotates, the two copper wires 6 located in the mold 1 are pressed together, so that the two copper wires 6 are initially combined, and then a casting pipe 5 is arranged between the first pressing roller 2 and the second pressing roller 3, and the copper liquid is cast into the mold 1 through the casting pipe 5, and the copper liquid fully flows around the copper wire body formed by the two copper wires 6, and then is pressed together by the rotation of the second pressing roller 3 to form a flat copper wire 601 to be formed.

[0035] It should be noted that the outer ring of the first pressing roller 2 may be provided with a plurality of thorn heads 201. When the first pressing roller 2 is rotated, the plurality of thorn heads 201 are sequentially pierced on the surface of the copper wire body formed by the two copper wires 6, and a plurality of thorn heads 201 may be formed on the surface of the copper wire body. Figure 5 The circular hole 602 shown in the figure, based on the setting of the circular hole 602, can allow the subsequent copper liquid to fully bite and fix with the copper wire 6, thereby increasing the strength and adhesion of the flat copper wire 601 to be formed.

[0036] Furthermore, since the piercing head 201 can form a circular hole 602 on the surface of the copper wire body, when the first pressing roller 2 rotates, it can also drive the copper wire body to move in the mold 1.

[0037] Furthermore, a plurality of second pressing rollers 3 may be provided, and the diameters of the plurality of second pressing rollers 3 may be successively increased. The plurality of second pressing rollers 3 rotate and cooperate at the same time to gradually press the flat copper wire 601 to be formed, so that the thickness of the flat copper wire 601 to be formed gradually decreases, thereby solving the problems of large power loss and easy cracking during one pressing.

[0038] It should also be noted that a plurality of mounting frames 101 are fixedly arranged on the side of the mold 1, and the plurality of mounting frames 101 are arranged at equal distances. The first pressing roller 2 and the second pressing roller 3 are rotatably arranged on the corresponding mounting frames 101, and the power mechanism includes a motor 4, which is installed on the mounting frame 101, and the motor 4 drives the corresponding first pressing roller 2 and the second pressing roller 3 to rotate.

[0039] Different numbers and specifications of second pressing rollers 3 can be provided according to actual needs, so as to process the flat copper wires 601 to be formed with various thickness specifications, which is highly practical.

[0040] In Example 2, reference Figure 6 As shown in , multiple molds 1 can be arranged in parallel, and the multiple first pressing rollers 2 between the multiple molds 1 are driven by the same motor 4, and the multiple second pressing rollers 3 are also driven by the same motor 4. Multiple flat copper wires 601 to be formed can be processed at the same time, which fully saves energy.

[0041] In Example 3, reference Figure 7 As shown in the figure, the mold 1 can be set as a rectangular box with a large opening at one end and an opening at the other end. This can facilitate the two copper wires 6 to initially enter the mold 1, and can also make the two copper wires 6 gradually approach each other and be pressed to form a flat copper wire 601 to be formed, avoiding the phenomenon that the two copper wires 6 may separate from each other or scratch the inner wall of the mold 1 when they are not pressed.

[0042] In Example 4, reference Figure 8 As shown in the figure, the mold 1 includes a side plate 11, a bottom plate 12, a connecting plate 13 and an intermediate plate 14. The bottom plate 12 is the bottom substrate, the side plates 11 are symmetrically arranged, the connecting plates 13 are fixedly welded to the sides of the two corresponding side plates 11 that are away from each other, and the connecting plates 13 are fixed to the upper surface of the bottom plate 12 by screws. The two symmetrical side plates 11 are arranged in multiple groups, and the multiple groups of side plates 11 are distributed along the length direction of the bottom plate 12. The side plates 11 between adjacent groups are fixedly connected by the intermediate plate 14. The thickness of the intermediate plate 14 is relatively small, which can be elastically deformed to a certain extent and maintain a certain strength. Therefore, the overall structure of the mold 1, such as: a large opening at one end and a small opening at the other end; small openings at both ends; large openings at both ends and S-shaped; are all adjustable.

[0043] When adjusting the overall structure of the mold 1, the connecting plate 13 can be installed at different positions on the bottom plate 12. The hole positions on the surface of the bottom plate 12 are not shown in the figure and will not be described here.

[0044] When the overall structure of the mold 1 is adjusted, S-shaped copper wires can be pressed together, and the scope of use is wider. Of course, the configuration of this embodiment is only an extension of the present invention, and will not be elaborated herein.
