Description

Technical Field

[0001] The invention relates to the field of cable production, and more specifically to a copper wire drawing annealing device for cable production. Background Art

[0002] Power cables are used to transmit and distribute electric energy. They 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 electric energy in the trunk lines of the power system.

[0003] Because the temperature of the copper wire is very high during the wire drawing and annealing process, the copper wire will immediately oxidize when it comes into contact with the air, and will produce copper rust when it comes into contact with water. Spots will appear on the surface of the copper wire, causing the qualified rate of the product to decrease. Therefore, anti-oxidation treatment is required.

[0004] The Chinese patent application with application number CN111719101A discloses a copper wire drawing annealing device for cable production, which is provided with an annular liquid inlet shell, and the annular liquid inlet shell is provided below the outer sleeve, and the annular liquid inlet shell is connected to a pumping pump, and the pumping pump can extract the coolant and spray it on the surface of the copper wire through the annular liquid inlet shell, so that the surface of the heated copper wire can be covered with a coolant film, and then the heated copper wire can be prevented from contacting with air before entering the coolant and oxidizing, thereby achieving an anti-oxidation effect. However, after annealing, the surface of the cable copper wire cannot be sprayed with the coolant film immediately, and at the same time, it will still be in contact with oxygen in the area from the annealing area to the spraying area, and there will be more or less oxidation.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This scheme is provided with an annealing protection component. The induction coil is energized to quickly heat the copper wire for annealing. The air pump extracts the inert gas (the inert gas can be nitrogen or argon) inside the inert gas tank, and the inert gas immediately fills the inside of the annealing shell. The inert gas can block the contact between the copper wire and oxygen, reduce the oxidation of the copper wire, improve the surface finish, and reduce waste gas emissions.

[0018] 2. This solution is provided with a pretreatment component. The gas flowing inside the annealing shell will carry a large amount of heat. Most of the gas moves to the inside of the heating chamber through the heat recovery pipe, and then sprays out through the air outlet. At the same time, the air outlet rotates inside the guide shell to increase the contact area between the airflow and the outer surface of the copper wire. A large amount of heat-carrying gas contacts the copper wire, which can preheat the copper wire and heat it to a certain temperature. Less heat is required during annealing and the annealing time is shorter, which can not only improve the utilization rate of energy, but also reduce the annealing time and effectively improve work efficiency.

[0019] 3. This solution is provided with a dust cleaning component. The driving motor drives the third gear to rotate at the same time. The third gear drives the cylinder to rotate through the second gear. The cleaning brush wipes the surface of the transmitted copper wire to remove dust and prevent impurities from adhering to its surface. Combined with the air flow ejected from the air outlet, the residual dust on the surface of the copper wire can be blown off. The double impurity removal setting further improves the cleanliness of the copper wire surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 8 A copper wire drawing annealing device for cable production includes a base 1, and the two sides of the upper surface of the base 1 are fixedly connected with a first support frame 2, a second support frame 3 and a third support frame 4 in sequence, and one side of the third support frame 4 is fixedly connected with an annealing protection component 5 for annealing the copper wire.

[0024] like Figure 2-3As shown, the annealing protection assembly 5 includes an annealing shell 51 fixed on one side of the third support frame 4 and an inert gas tank 53 fixed on the upper surface of the second support frame 3, a through hole 57 is opened on one side of the annealing shell 51, a connecting pipe 510 is fixedly connected to the other side of the annealing shell 51, an induction coil 59 is fixedly connected to the inner surface of the annealing shell 51, an air pump 52 is fixedly connected to one side of the upper surface of the annealing shell 51, a sleeve plate 54 is fixedly connected to the side of the annealing shell 51 close to the through hole 57, a guide wheel frame 56 is slidably connected to the inside of the sleeve plate 54, and a spring 55 is fixedly connected to one side of the guide wheel frame 56.

[0025] The output end of the air pump 52 extends to the inside of the annealing shell 51, and the input end of the air pump 52 extends to the inside of the inert gas tank 53. One side of the spring 55 is fixedly connected to one side of the annealing shell 51. The guide wheel frame 56 consists of an H-shaped frame and a guide wheel, and the guide wheel is rotatably connected to the inside of the H-shaped frame.

[0026] When the copper wire is annealed, the copper wire is passed through the connecting pipe 510 into the interior of the annealing shell 51 and output from the interior of the through hole 57. At this time, the induction coil 59 is energized to quickly heat the copper wire inside the annealing shell 51 for annealing. Before this, the air pump 52 is turned on, and the inert gas (the inert gas can be nitrogen or argon) inside the inert gas tank 53 is transported to the annealing shell 51 through the air pump 52. The inert gas then fills the interior of the annealing shell 51. The inert gas can prevent the copper wire and oxygen from contacting each other, reduce oxidation of the copper wire, improve surface finish, and reduce waste gas emissions. The traditional pickling process can be effectively reduced. The copper wire bypasses the outer surface of the guide wheel frame 56 and moves downward. The spring 55 pushes the guide wheel frame 56 to extrude and draw the copper wire, so that the copper wire is subjected to a certain tension during annealing, ensuring that the copper wire will not bend due to annealing in the annealing shell 51.

[0027] like Figure 3-4 As shown, a pretreatment component 58 for preheating the steel wire is provided on one side of the connecting pipe 510, and the pretreatment component 58 includes a heating chamber 582 fixed on one side of the connecting pipe 510, a heat recovery pipe 581 is fixedly connected to the bottom of the heating chamber 582, one end of the heat recovery pipe 581 is fixedly connected to a guide shell 584, the inner surface of the guide shell 584 is rotatably connected to an air outlet tube 587, the inner surface of the air outlet tube 587 is evenly provided with air outlet holes 588, an annular rack 586 is fixedly connected to one side of the outer surface of the air outlet tube 587, a driving motor 583 is fixedly connected to the bottom of one side of the heating chamber 582, and the output end of the driving motor 583 is fixedly connected to a first gear 585.

[0028] The top of the heat recovery pipe 581 extends into the heating chamber 582. The diversion shell 584 is located inside the heating chamber 582. The output end of the drive motor 583 extends into the diversion shell 584. The first gear 585 meshes with the annular rack 586. The drive motor 583 is fixed to one side of the heating chamber 582 through a C-shaped frame. The front and rear sides of the heating chamber 582 are fixedly connected to the first support frame 2.

[0029] In a cold environment, the temperature of the copper wire itself is low. When the copper wire enters the annealing shell 51 and is heated to the annealing temperature, a large amount of energy is consumed, and the heat generated during annealing cannot be fully utilized, resulting in low energy utilization efficiency. Therefore, before annealing, the copper wire passes through the inside of the heating chamber 582, passes through the middle of the diversion shell 584, and enters the annealing shell 51 through the connecting pipe 510. A large amount of heat is generated during the annealing process. When the air pump 52 transports the inert gas into the annealing shell 51, the gas inside the annealing shell 51 flows, and the flowing gas will carry a large amount of heat and move. Most of the gas moves through the inside of the heat recovery pipe 581 into the heating chamber 582, and then is ejected through the air outlet hole 588. Then, the drive motor 583 is turned on to drive the first gear 585 to rotate. The first gear 585 drives the air outlet cylinder 587 to rotate inside the diversion shell 584 through the annular rack 586, increasing the contact area between the air flow and the outer surface of the copper wire. A large amount of gas carrying heat contacts the copper wire, and the copper wire can be preheated. When the copper wire heated to a certain temperature enters the annealing shell 51 for annealing, less heat is required and the annealing time is shorter. This can not only improve the energy utilization rate but also reduce the annealing time, effectively improving the work efficiency.

[0030] As Figure 5 shown, a dust cleaning component 589 is provided on the side of the heating chamber 582 away from the connecting pipe 510. The dust cleaning component 589 includes a cylinder 5891 rotatably connected to one side of the heating chamber 582 and a third gear 5894 fixed to the outer surface of the output end of the drive motor 583. A cleaning brush 5893 is provided on the inner surface of the cylinder 5891. A second gear 5892 is rotatably connected to the outer surface of the cylinder 5891. The third gear 5894 meshes with the second gear 5892.

[0031] When the copper wire is pre-treated and heated, work efficiency can be improved and energy consumption can be reduced. However, one of the key points affecting the annealing quality is that the surface of the annealed copper wire needs to ensure cleanliness. If there are impurities and dust, the annealing quality of the copper wire will be reduced. Therefore, when the copper wire enters the interior of the heat recovery pipe 581, it first contacts the cleaning brush 5893 through the interior of the cylinder 5891. When the drive motor 583 works and drives the first gear 585 to rotate, the drive motor 583 also drives the third gear 5894 to rotate. The third gear 5894 drives the cylinder 5891 to rotate through the second gear 5892. The cleaning brush 5893 wipes the surface of the transmitted copper wire to remove dust and prevent impurities from adhering to its surface. Combined with the airflow ejected from the air outlet 588, the residual dust on the surface of the copper wire can be blown off. The double impurity removal setting further improves the cleanliness of the copper wire surface.

[0032] like Figure 6 As shown, a wire drawing assembly 6 is provided in the middle of one side of the upper surface of the base 1, and the wire drawing assembly 6 includes a fourth support frame 61 fixed on one side of the upper surface of the base 1, and mounting plates 62 are fixedly connected to both sides of the inner surface of the fourth support frame 61, and a wire drawing die 63 is rotatably connected to the upper surface of the mounting plate 62, and wire drawing holes 65 are evenly opened inside the wire drawing die 63, and steering wheels 64 are rotatably connected to both sides of the inner surface of the fourth support frame 61 near the bottom.

[0033] There are four drawing holes 65 , each with a different diameter. A threaded rod is threadedly connected to one side of the mounting plate 62 . A positioning hole is provided at the edge of the bottom of the drawing die 63 , and the top of the threaded rod extends to the inside of the positioning hole.

[0034] When drawing wires, it is often necessary to draw the copper wire into wires of different diameters, and the mold needs to be constantly replaced, which wastes time and reduces work efficiency. At this time, the threaded rod is rotated to move the threaded rod out from the inside of the positioning hole, and the wire drawing die 63 can be rotated to rotate the required wire drawing hole 65 to the bottom of the guide wheel frame 56. The copper wire moves to the inside of the wire drawing hole 65 through the guide wheel frame 56, and is pulled into the required diameter. The copper wire is then guided by the steering wheel 64 to the next process.

[0035] like Figure 7-8 As shown, a lubrication assembly 66 is provided in the middle of the upper surface of the fourth support frame 61, and the lubrication assembly 66 includes an oil storage chamber 661 fixed on the top of the fourth support frame 61, and a connecting chamber 662 is fixedly connected to the lower surface of the oil storage chamber 661, and a sponge 663 is fixedly connected to the inner surface of the connecting chamber 662, and two connecting sponges 664 are symmetrically arranged on the outer side of the sponge 663.

[0036] An oil inlet is provided on the upper surface of the oil storage chamber 661 , and a sealing plug is provided inside the oil inlet. One side of the connecting sponge 664 extends to the inside of the connecting chamber 662 , and the inside of the connecting chamber 662 is connected to the inside of the oil storage chamber 661 .

[0037] The inner diameter of the sponge 663 is smaller than the inner diameter of the oil storage cavity 661 , and the axis of the sponge 663 coincides with the axis of the wire drawing hole 65 .

[0038] Before the copper wire is drawn, a huge friction force is generated between the copper wire and the drawing hole 65. The friction force requires a greater traction force during drawing. Excessive traction force may tear the copper wire after drawing and cause wear on the copper wire, resulting in reduced strength and quality of the copper wire. For this reason, before wire drawing, the copper wire will first pass through the interior of the oil storage chamber 661 and the interior of the sponge 663, and the copper wire will fully contact the inner side of the sponge 663. The lubricating oil inside the oil storage chamber 661 will contact the connecting sponge 664 through the connecting chamber 662. The oil will flow to the interior of the sponge 663 through the connecting sponge 664 to soak the sponge 663. The sponge 663 covered with lubricating oil will smear the oil on the surface of the copper wire, so that when the copper wire enters the interior of the wire drawing hole 65, the friction can be greatly reduced, and the required traction force is also smaller, thereby avoiding the breakage of the copper wire and improving the production qualification rate.

[0039] Usage: Power on the induction coil 59 to quickly heat the copper wire inside the annealing shell 51 for annealing. Before that, turn on the air pump 52, and use the air pump 52 to transport the inert gas (the inert gas can be nitrogen or argon) inside the inert gas tank 53 to the inside of the annealing shell 51. The inert gas will then fill the inside of the annealing shell 51. The inert gas can prevent the copper wire from contacting oxygen, reduce the oxidation of the copper wire, improve the surface finish, and reduce waste gas emissions, which can effectively reduce the traditional pickling process. The copper wire bypasses the outer surface of the guide wheel frame 56 and moves downward, entering the inside of the wire drawing assembly 6 for wire drawing. The spring 55 pushes the guide wheel frame 56 to extrude and draw the copper wire, so that the copper wire is subjected to a certain tension during annealing, ensuring that the copper wire will not bend inside the annealing shell 51 due to annealing.

[0040] The copper wire passes through the interior of the heating chamber 582, passes through the middle of the guide shell 584, and enters the interior of the annealing shell 51 through the connecting pipe 510. A large amount of heat will be generated during the annealing process. When the air pump 52 delivers the inert gas to the interior of the annealing shell 51, the gas inside the annealing shell 51 flows, and the flowing gas will move with a large amount of heat. Most of the gas moves to the interior of the heating chamber 582 through the interior of the heat recovery pipe 581, and then sprays out through the air outlet 588. Then the driving motor 583 is turned on to drive the first gear 585 to rotate. The first gear 585 drives the air outlet tube 587 to rotate inside the guide shell 584 through the annular rack 586, thereby increasing the contact area between the airflow and the outer surface of the copper wire. A large amount of gas carrying heat contacts the copper wire, and the copper wire can be preheated.

[0041] The inside of the cylinder 5891 contacts the cleaning brush 5893. When the driving motor 583 works and drives the first gear 585 to rotate, the driving motor 583 also drives the third gear 5894 to rotate. The third gear 5894 drives the cylinder 5891 to rotate through the second gear 5892. The cleaning brush 5893 wipes the surface of the transmitted copper wire to remove dust and prevent impurities from adhering to its surface. Combined with the air flow ejected from the air outlet 588, the residual dust on the surface of the copper wire can be blown off. The double impurity removal setting further improves the cleanliness of the copper wire surface.

[0042] The copper wire will first pass through the interior of the oil storage chamber 661 and the interior of the sponge 663. The copper wire is in full contact with the inner side of the sponge 663. The lubricating oil in the oil storage chamber 661 contacts the connecting sponge 664 through the connecting chamber 662. The oil flows to the interior of the sponge 663 through the connecting sponge 664 to soak the sponge 663. The sponge 663 covered with lubricating oil smears the oil on the surface of the copper wire, so that when the copper wire enters the interior of the drawing hole 65, the friction can be greatly reduced, and the required traction force is also smaller, thereby avoiding the breakage of the copper wire and improving the production qualification rate.

[0043] The wire drawing die 63 is rotated to rotate the required wire drawing hole 65 to the bottom of the guide wheel frame 56. The copper wire moves to the inside of the wire drawing hole 65 through the guide wheel frame 56. The copper wire is pulled into the required diameter by pulling. The copper wire is then moved to the next process under the guidance of the steering wheel 64.

[0044] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
