[0002] Power cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the trunk lines of power systems. In the production of cable copper wires, copper wires usually need to be drawn first. The usual drawing method is to draw the copper wire through a die to the required diameter. During the drawing process, the copper wire will be gradually drawn into the required diameter through multiple dies. This method requires Multiple dies are required, and the wire drawing production cycle is long and the cost is high. After the wire drawing is completed, multiple annealing is required to eliminate the internal stress generated during the wire drawing process. Since the copper wires are drawn to the required diameter through the die, large internal stress will be generated between the copper wires during the wire drawing process.

[0032] Example 1

[0033] Reference Figure 1-Figure 8 As shown, the present invention is a wire drawing annealing device for copper wire cable processing, comprising a wire drawing annealing box 1, wherein the wire drawing annealing box 1 is functionally divided into three areas, including a wire dividing chamber 2, a wire drawing annealing chamber 3 and a cooling chamber 4;

[0034] A wire drawing annealing box 1 is provided with a wire drawing annealing mechanism, which is used for wire drawing and annealing of copper wire. The wire drawing annealing mechanism includes an upper steering wheel 13, a lower steering wheel 12 and a driving shaft wheel 9. The driving shaft wheel 9 is driven and rotated by a motor. The driving shaft wheel 9 is used for the wire winding operation after the copper wire is drawn and annealed. The upper steering wheel 13 and the lower steering wheel 12 can guide the copper wire. The upper steering wheel 13 is used for guiding the thick copper wire, and the lower steering wheel 12 is used for guiding the thin copper wire. A cooling hood 8 is provided on one side of the driving shaft wheel 9. The cooling hood 8 is filled with a coolant for cooling the copper wire after annealing. A liquid adding pipe for replenishing the coolant and a recovery pipe for recovering the hot coolant are respectively provided at the upper and lower ends of the cooling hood 8. An annealing furnace 10 is provided on one side of the cooling hood 8. The annealing furnace 10 is used for the annealing operation of the copper wire after drawing. After being stretched, the hardness of the copper wire increases and it is brittle. The plasticity and toughness of the copper wire are improved after annealing.

[0035] The cooling cover 8 and the driving shaft wheel 9 are arranged in the cooling chamber 4 , and a wire outlet 16 is arranged on one side of the cooling chamber 4 .

[0036] A wire dividing mechanism 5 is provided in the wire drawing annealing box 1. The wire dividing mechanism 5 is used for identifying the diameter of the copper wire and guiding the drawing paths of copper wires of different sizes. The wire dividing mechanism 5 includes a wire dividing seat 51, on which an adjusting seat 52 is slidably mounted. An electric push rod is provided in the wire dividing seat 51, and the electric push rod piston rod is connected to the adjusting seat 52. The adjusting seat 52 is driven to move by the electric push rod, thereby driving the thick wire dividing wheel 53 and the thin wire dividing wheel 54 to move, so as to adjust the tension of the copper wire during the wire drawing process and reduce the abnormal deformation and cracking of the copper wire. In the present invention, when the thick copper wire and the thin copper wire are drawn, the tension requirements of the thick copper wire and the thin copper wire are not the same. Generally speaking, the tension of the thick copper wire is relatively large. The tension of the thin copper wire is relatively high, and a retractable adjustment seat 52 is used to control the tension of the copper wires of different diameters during the wire drawing process, thereby improving the wire drawing quality. A thick wire dividing wheel 53 and a thin wire dividing wheel 54 are respectively arranged on both sides of the end of the adjustment seat 52. The thick wire dividing wheel 53 and the thin wire dividing wheel 54 are installed on the adjustment seat 52 through a connecting rod 55. A laser sensor 56 is arranged on the adjustment seat 52. The laser sensor 56 is used to identify the diameter of the copper wire and guide the guide path of the copper wire according to the diameter of the copper wire; according to the diameter of the copper wire, the copper wire of the set thick diameter is guided through the thick wire dividing wheel 53, and the copper wire of the set thin diameter is guided through the thin wire dividing wheel 54;

[0037] The wire dividing mechanism 5 is arranged in the wire dividing chamber 2. One side of the wire dividing chamber 2 is connected with a wire inlet pipe 11. A wire dividing plate 14 is arranged between the wire dividing chamber 2 and the wire drawing annealing chamber 3. The wire dividing plate 14 has wire inlets 15 at both ends. The wire dividing seat 51 is installed on one side of the wire dividing plate 14.

[0038] A wire drawing adjustment mechanism 6 is provided in the wire drawing annealing box 1, and the wire drawing adjustment mechanism 6 is used for processing copper wires of different sizes;

[0039] The wire drawing adjustment mechanism 6 includes a fixed plate 61, on which a plurality of lubricating wheels 62 are arranged in equal arcs. The plurality of lubricating wheels 62 are mounted on the fixed plate 61 through a rotating rod.

[0040] The lubricating wheel 62 includes two wheel feet 621 and a guide groove 622 between the two wheel feet 621. The two wheel feet 621 are provided with a top support groove 628 on the opposite side. An oil cover 623 is slidably installed in the top support groove 628. A plurality of oil overflow holes 624 are provided on one side of the oil cover 623. An oil pressure plate 626 is slidably installed in the oil cover 623. Lubricant 625 is filled between the oil cover 623 and the oil pressure plate 626. A plurality of elastic members 627 are provided in the top support groove 628. The plurality of elastic members 627 and the oil pressure plate 626 are connected to each other. 626 is connected to one side, and the oil pressing plate 626 is supported by the elastic member 627. The oil pressing plate 626 drives the oil cover 623 to contact the two sides of the copper wire. At the same time, the oil pressing plate 626 presses the lubricant 625 in the oil cover 623 to overflow from the overflow hole 624, and the lubricant 625 is applied to the two sides of the copper wire, so that the lubricating liquid can continuously replenish the lubricant 625 during the wire drawing process, ensuring that the copper wire is always in a lubricated state during the drawing process, reducing local overheating and breakage caused by excessive friction. The elastic member 627 is a spring;

[0041] A plurality of preheating holes 63 are provided on the fixing plate 61, and the preheating holes 63 are used to preheat the copper wire to avoid a large temperature difference during the wire drawing process, reduce stress concentration caused by the temperature difference, and relieve the internal stress of the copper wire during the drawing process;

[0042] An electric heating wire is arranged in the fixed disk 61, and the gas in the wire drawing annealing box 1 is heated by the electric heating wire, so that the copper wire can be evenly heated in the heated gas. One side of the fixed disk 61 is connected to multiple special gas supply pipes, and the special gas is a special anti-oxidation gas such as nitrogen to prevent the copper wire from oxidizing during the preheating process;

[0043] When drawing the thin copper wire, the thin copper wire passes through the wire inlet tube 11 and the thin wire dividing wheel 54 and passes through the lower steering wheel 12, passes between two symmetrical lubricating wheels 62 on the fixed disk 61, and the thin copper wire is fully lubricated by the two lubricating wheels 62, so that the copper wire is always in a lubricated state during the wire drawing process. At the same time, the copper wire passes through the fixed disk 61 between the two lubricating wheels 62, and the copper wire is preheated by the fixed disk 61 to reduce stress concentration caused by temperature difference, which is convenient for subsequent annealing operations;

[0044] When drawing the thick copper wire, the thick copper wire passes through the wire inlet tube 11 and the thick wire dividing wheel 53 and passes through the upper steering wheel 13, and then crosses through the multiple lubrication wheels 62 on the fixed disk 61 in turn. Since the thick copper wire is relatively thick, it needs to pass through multiple lubrication wheels 62 for wire drawing. When lubricating the thick copper wire, the multiple lubrication wheels 62 meet the requirement of gradually drawing and thinning the thick copper wire. At the same time, since the thick copper wire preheats slowly, the cross-arranged thick copper wire can be maintained on the fixed disk 61 for a long time, meeting the preheating requirement of the thick copper wire.

[0045] A recovery sleeve 7 is provided on one side of the wire drawing adjustment mechanism 6. The recovery sleeve 7 is filled with a brush surface, and the brush surface is soaked with a cleaning agent. The cleaning agent is ethanol, petroleum ether, etc., which is used to remove the lubricant 625 attached to the surface of the copper wire to avoid affecting the subsequent annealing. The lubricating oil generally contains organic chemical components, which are easy to decompose and release harmful gases at high temperatures. These gases will not only pollute the atmosphere of the annealing furnace 10, but may also cause uneven oxides to form on the surface of the copper wire, affecting the quality of the copper wire.

[0046] Working principle:

[0047] When drawing the thin copper wire, the thin copper wire passes through the wire inlet tube 11 and the thin wire dividing wheel 54 and passes through the lower steering wheel 12, passes through the two symmetrical lubricating wheels 62 on the fixed disk 61, and the thin copper wire is fully lubricated by the two lubricating wheels 62, so that the copper wire is always in a lubricated state during the wire drawing process. At the same time, the copper wire passes through the fixed disk 61 between the two lubricating wheels 62, and the copper wire is preheated by the fixed disk 61 to reduce stress concentration caused by temperature differences, which is convenient for subsequent annealing operations. After the thin copper wire is recovered by the recovery sleeve 7, the lubricant 625 is successively annealed in the annealing furnace 10 and cooled by the cooling cover 8, and the processed copper wire is taken up by the driving shaft wheel 9;

[0048] When drawing the thick copper wire, the thick copper wire passes through the wire inlet tube 11 and the thick wire dividing wheel 53 and passes through the upper steering wheel 13, and then crosses and passes through the multiple lubrication wheels 62 on the fixed plate 61 in turn. Since the thick copper wire is thick in size, it needs to pass through multiple lubrication wheels 62 for drawing. When lubricating the thick copper wire, the multiple lubrication wheels 62 meet the requirement of gradually drawing and thinning the thick copper wire.

[0049] At the same time, since the thick copper wire preheats slowly, the cross-arranged thick copper wire can be maintained on the fixed disk 61 for a long time, meeting the preheating requirements of the thick copper wire. The thick copper wire passes through the recovery sleeve 7 and is successively annealed in the annealing furnace 10 and cooled by the cooling hood 8, and the processed copper wire is wound up by the driving shaft wheel 9.
