Description

Technical Field

[0001] The present invention relates to the field of flat copper wires, and in particular to a high-strength flat copper wire. Background Art

[0002] Flat copper wire is a data cable pressed together by a laminating machine. It is soft, thin, and small in size. It has excellent bending resistance and the number and spacing of wires can be arbitrarily selected for easy connection.

[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 large, it is undoubtedly necessary to increase the pressing force of the pressing roller and other mechanisms. This not only consumes energy, but also the copper wire body with a large diameter will be easily 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 purpose 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 a mechanism such as a pressing roller, 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 during flattening.

[0006] To achieve the above object, the present invention provides the following technical solutions: a high-strength flat copper wire, comprising a flat copper wire comprising at least two copper wires and a copper body structure formed after solidification of copper liquid;

[0007] At least two copper wires are intertwined and braided to form a copper wire body;

[0008] 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.

[0009] Preferably, the flat copper wire comprises the following preparation method:

[0010] Step 1: Prepare at least two copper wires and copper liquid;

[0011] Step 2: Wrap the two copper wires around each other and weave them to form a chain-like copper wire body. Then, use a mold to accommodate the copper wire body and press the copper wire body in the mold. While pressing, pour copper liquid around the copper wire body. The copper liquid is fully mixed with the copper wire body and pressed again to form a flat copper wire to be formed. After the formed flat copper wire is completely cooled, it forms a flat copper wire.

[0012] Preferably, the pressing device for 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;

[0013] a first pressing roller, which is rotatably disposed in the mold and is used for preliminarily pressing the copper wire body;

[0014] The second pressing roller is rotatably arranged in the mold and is used for secondary pressing of the copper wire body.

[0015] Preferably, the mold is a concave-shaped trough.

[0016] Preferably, a plurality of thorns are evenly and fixedly provided on the outer ring of the first pressing roller.

[0017] 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.

[0018] Preferably, a plurality of mounting frames distributed at equal distances are fixedly provided on the mold, and the first pressing roller and the second pressing roller are rotatably provided on corresponding mounting frames.

[0019] Preferably, the mold is provided with a motor, and the motor is used to drive the first pressing roller and the second pressing roller to rotate.

[0020] Preferably, a plurality of the molds are arranged in parallel;

[0021] One end of the mold has a large opening, and the other end has a small opening.

[0022] Preferably, the mold includes side panels, a bottom plate, a connecting plate and an intermediate plate. The side panels are symmetrically arranged, the connecting plates are fixedly welded to the sides of the two corresponding side panels that are away from each other, and the connecting plates are fixed to the upper surface of the bottom plate by screws. The two symmetrical side panels are provided in multiple groups, and the multiple groups of side panels are distributed along the length direction of the bottom plate. The side panels between adjacent groups are fixedly connected by the intermediate plate.

[0023] The technical effects and advantages of the present invention are as follows:

[0024] The present invention combines braiding, casting and pressing processes, and uses two copper wires with smaller diameters to twist and weave together to form a copper wire body. Compared with copper wire bodies with larger diameters, copper wire bodies are easier to press and deform, and are less likely to crack, shift or break.

[0025] When the flat copper wire to be formed is pressed and formed, the copper liquid that has just cooled and solidified fully combines with the two copper wires, so that the two copper wires and the copper body formed by the condensation of the copper liquid are interlocked and not easy to delaminate, the overall strength is high, and the adhesion of the flat copper wire is improved;

[0026] The circular hole arrangement allows for subsequent copper liquid to fully engage and fix with the copper wire, thereby increasing the strength and adhesion of the flat copper wire to be formed. Furthermore, the circular hole formed by the thorn head on the surface of the copper wire body allows the copper wire body to move in the mold when the first pressing roller rotates.

[0027] The diameters of the multiple second pressing rollers can be gradually increased, and the multiple second pressing rollers rotate and cooperate simultaneously to gradually press the flat copper wire to be formed, so that the thickness of the flat copper wire to be formed can be gradually reduced, solving the problems of large power loss and easy cracking during one pressing;

[0028] According to actual needs, different numbers and specifications of second pressing rollers can be set to process flat copper wires with various thicknesses and specifications, which is highly practical;

[0029] By adjusting the overall structure of the mold, S-shaped copper wires can be pressed together, which has a wider range of uses. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In embodiment 1, the present invention provides Figure 9 A high-strength flat copper wire is shown in FIG. , which includes a flat copper wire 10 formed by braiding, casting and pressing processes. First, at least two copper wires 6 and copper liquid are prepared.

[0041] like Figure 4 As 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. 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. The copper liquid is fully mixed with the copper wire body, and after being pressed by a mechanism similar to a pressing roller, a copper wire body is formed. Figure 3 The flat copper wire 601 to be formed is shown in FIG. ; the production process of the flat copper wire 601 to be formed is superior to the existing technology and ensures the basic strength of the flat copper wire 601 to be formed.

[0042] In the prior art, when flattening copper wire, a mechanism such as a pressing roller is usually used to directly flatten the copper wire, and there are both cold pressing and hot pressing methods.

[0043] 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 large, it is undoubtedly necessary to increase the pressing force of the pressing roller and other mechanisms. This not only consumes energy, but also the copper wire body with a large diameter will be easily deformed to a large extent when flattened, which will easily cause problems such as cracking, position displacement or breakage.

[0044] Therefore, the present invention combines weaving, casting and pressing processes, and uses two copper wires 6 with smaller diameters to be twisted and weaved together to form a copper wire body. Compared with the copper wire body with larger diameter, it is easier to press and deform, and is less likely to have problems such as cracking, position displacement or breakage.

[0045] While pressing the two copper wires 6 to form the copper wire body, casting the copper liquid simultaneously can make the copper liquid fully fill the gaps in 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 easily delaminated, the overall strength is high, and the adhesion of the flat copper wire is improved.

[0046] 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.

[0047] In embodiment 1, a pressing device for pressing the flat copper wire 601 to be formed is also provided, such as Figures 1 to 3 As 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, it presses the two copper wires 6 located in the mold 1 so that the two copper wires 6 are initially combined, and then a casting pipe 5 is provided 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 by the rotation of the second pressing roller 3 to form a flat copper wire 601 to be formed.

[0048] 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 engage and fix with the copper wire 6, thereby increasing the strength and adhesion of the flat copper wire 601 to be formed.

[0049] 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.

[0050] Furthermore, multiple second pressing rollers 3 can be provided, and the diameters of the multiple second pressing rollers 3 can be successively larger. The multiple 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 can be gradually reduced, solving the problem of large power loss and easy cracking during one pressing.

[0051] It should also be noted that a plurality of mounting frames 101 are fixedly provided 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 provided 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.

[0052] 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 thicknesses and specifications, which is highly practical.

[0053] In Example 2, reference Figure 6 As shown in the figure, 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.

[0054] 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 open end at the other end. This can facilitate the initial entry of the two copper wires 6 into the mold 1, and can also enable the two copper wires 6 to gradually approach each other and be pressed to form the flat copper wire 601 to be formed, thereby 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.

[0055] In Example 4, reference Figure 8 As shown in the figure, the mold 1 includes side panels 11, a bottom panel 12, a connecting panel 13 and an intermediate panel 14. The bottom panel 12 is the bottom substrate. The side panels 11 are symmetrically arranged. The connecting panels 13 are fixedly welded to the sides of the two corresponding side panels 11 that are away from each other. The connecting panels 13 are fixed to the upper surface of the bottom panel 12 by screws. The two symmetrical side panels 11 are provided with multiple groups. The multiple groups of side panels 11 are distributed along the length direction of the bottom panel 12. The side panels 11 between adjacent groups are fixedly connected by the intermediate panel 14. The thickness of the intermediate panel 14 is relatively small, which can achieve a certain degree of elastic deformation 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.

[0056] 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.

[0057] 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 setting method of this embodiment is only an extension of the present invention and will not be elaborated here.
