Technical Field
[0001] The present invention relates to the technical field of power transmission, and in particular to an aluminum alloy wire processing method and a processing production line. Background Art
[0002] Aluminum alloy wires have been widely used in the field of power transmission due to their advantages such as light weight, corrosion resistance, and good electrical conductivity. However, with the continuous growth of electricity demand and the continuous advancement of power grid technology, the performance requirements for aluminum alloy wires are becoming higher and higher. As overhead conductors, they need to withstand the test of various environmental conditions and mechanical stresses. First of all, in outdoor environments, conductors need to withstand the erosion of natural factors such as wind, rain, and temperature changes, which requires the conductor material to have high strength and toughness to prevent breakage or deformation due to external forces; secondly, as a conductive carrier, its conductivity is also an important indicator to measure its performance. High conductivity means smaller resistance and higher energy transmission efficiency, which is of great significance for reducing power loss and improving the efficiency of power grid operation.
[0003] The processing methods of aluminum alloy wires in the related art usually include the following methods: 1) first cast the aluminum alloy into aluminum ingots, and then use an extrusion process to form alloy wires; 2) cast the aluminum alloy into aluminum ingots, and then use a hot rolling process to form alloy wires; 3) prepare aluminum alloy wires through continuous casting and rolling processes. The above-mentioned processing methods usually also include solid solution treatment and aging treatment, but in the prior art, solid solution treatment and aging treatment are usually carried out separately from the deformation process, which will cause the microstructure and properties of the formed aluminum alloy wire to be extremely uneven, and it is impossible to meet the requirements of high strength and high conductivity at the same time; in addition, the additional heat treatment process will also lead to reduced production efficiency and increased production costs.
[0004] Therefore, there is an urgent need for an aluminum alloy wire processing method to solve the above problems. Summary of the invention

To this end, the object of the present invention is to provide an aluminum alloy wire processing method and a processing production line, which can ensure that the formed aluminum alloy wire meets the performance requirements of high strength and high conductivity, and can improve production efficiency and reduce production costs.

[0053] Figure 1 FIG. 2 shows a schematic diagram of the structure of the aluminum alloy wire processing production line provided in this embodiment. Figure 1 As shown, this embodiment provides an aluminum alloy wire processing production line, which includes a feeding mechanism 200, a winding mechanism 300, and an extrusion mechanism 400, a temperature control mechanism 500 and a drawing mechanism 600 located therebetween; the feeding mechanism 200 is used to transfer the aluminum alloy rod material 101 to the extrusion mechanism 400; the extrusion mechanism 400 is configured to extrude the aluminum alloy rod material 101 transferred thereto into an intermediate wire 102; the temperature control mechanism 500 is configured to cool and keep the intermediate wire 102 warm; the drawing mechanism 600 is configured to use a drawing process to shape the cooled intermediate wire 102 into a finished wire 103; the winding mechanism 300 is used to wind the finished wire 103.
[0054] The aluminum alloy wire processing production line provided in the present embodiment can cool and keep the extruded intermediate wire 102 warm by setting a temperature control mechanism 500. The warm-keeping process can reduce the temperature difference between the center and the surface of the intermediate wire 102. After cooling, the drawing mechanism 600 can use the residual temperature of the intermediate wire 102 to draw it at medium and low temperatures, which can not only refine the grain structure, but also form fine nano-precipitated phases synchronously through dynamic aging, thereby improving the strength and conductivity of the finished wire 103; through the cooperation of the feeding mechanism 200 and the winding mechanism 300, continuous extrusion, drawing and heat treatment of the aluminum alloy wire can be achieved, and the link of transferring the wire between two adjacent processes is omitted, avoiding the uneven organizational performance of the finished wire 103, thereby ensuring that the finished wire 103 meets the performance requirements of high strength and high conductivity, and can improve production efficiency and reduce production costs.
[0055] Furthermore, the feeding mechanism 200 includes a guide pressing wheel 201 and an extrusion wheel 202, the axis of the guide pressing wheel 201 and the axis of the extrusion wheel 202 are parallel, the aluminum alloy bar stock 101 can pass through the gap between the guide pressing wheel 201 and the extrusion wheel 202, and the guide pressing wheel 201 and the extrusion wheel 202 rotate in opposite directions to transfer the aluminum alloy bar stock 101 to the extrusion mechanism 400. This arrangement can simplify the structure of the feeding mechanism 200 and realize continuous transfer of the aluminum alloy bar stock 101.
[0056] Optionally, the feeding mechanism 200 further includes a feeding drive assembly (not shown in the figure), the output end of which is connected to the extrusion wheel 202 to drive the extrusion wheel 202 to rotate, and the guide pressure wheel 201 can rotate synchronously driven by the aluminum alloy rod 101. The guide pressure wheel 201 is mainly used to provide pressure for the aluminum alloy rod 101, so that the aluminum alloy rod 101 can be smoothly transmitted to the extrusion mechanism 400 to avoid bending and twisting during the transmission process, which affects the extrusion effect. This embodiment does not limit the specific structure of the feeding drive assembly, which can be a driving device with a rotation drive function such as a motor, a motor plus a gear, etc.
[0057] Of course, in other embodiments, the feed drive assembly can also be set to two, where one feed drive assembly is used to drive the guide pressing wheel 201 to rotate, and the other feed drive assembly is used to drive the extrusion wheel 202 to rotate, which can also achieve the above-mentioned effect.
[0058] Optionally, the rotation speed of the extrusion wheel 202 is 3 r / min to 20 r / min. Exemplarily, the rotation speed of the extrusion wheel 202 may be 4 r / min, 5 r / min, 6 r / min, 7 r / min, 8 r / min, 9 r / min, 10 r / min, 11 r / min, 12 r / min, 13 r / min, 14 r / min, 15 r / min, 16 r / min, 17 r / min, 18 r / min, 19 r / min, etc. This embodiment does not limit the rotation speed of the extrusion wheel 202, and the operator may adjust it according to actual processing needs.
[0059] It should be noted that the extrusion mechanism 400 is an extrusion die commonly used in the art, and the specific structure of the extrusion die is not described in detail in this embodiment. In this embodiment, the diameter of the aluminum alloy rod material 101 is 10 mm to 30 mm, preferably 16 mm; the diameter of the intermediate wire material 102 after extrusion molding by the extrusion mechanism 400 is 3 mm to 15 mm, preferably 8 mm.
[0060] like Figure 1As shown, the temperature control mechanism 500 includes a first cooling component 510 and a heat preservation component 520. The first cooling component 510 is located upstream of the heat preservation component 520. The first cooling component 510 is used to cool the extruded intermediate wire 102, and the heat preservation component 520 is used to keep the cooled intermediate wire 102 warm to reduce the temperature difference between the center and the surface of the intermediate wire 102. In this embodiment, the temperature of the intermediate wire 102 at the outlet of the extrusion mechanism 400 is about 450°C to 550°C. After being cooled and kept warm by the temperature control mechanism 500, the temperature of the intermediate wire 102 at the outlet of the heat preservation component 520 is about 150°C to 250°C. Among them, the cooling rate of the first cooling component 510 is 20°C / s-50°C / s. This embodiment does not limit the cooling rate of the first cooling component 510, and the operator can adjust it according to actual processing needs.
[0061] Optionally, a temperature measuring element is provided at the entrance and exit of the heat preservation component 520 to measure the temperature of the intermediate wire 102 at the entrance of the heat preservation component 520 and the intermediate wire 102 at the exit of the heat preservation component 520, so as to ensure that the intermediate wire 102 can be transmitted to the drawing mechanism 600 at an optimal temperature for drawing. In this embodiment, the temperature measuring element can be a temperature sensor, which is sensitive in temperature measurement and low in cost. This embodiment does not limit the specific structure of the heat preservation component 520, and the heat preservation devices that can realize online heat preservation of the intermediate wire 102 in the prior art are all within the protection scope of this embodiment.
[0062] The first cooling assembly 510 includes a cooling drive 511 and a cooling blade 512. The output end of the cooling drive 511 is connected to the cooling blade 512. The cooling blade 512 faces the middle wire 102. When the cooling drive 511 is working, it can drive the cooling blade 512 to rotate to air-cool the middle wire 102. Optionally, there are two first cooling assemblies 510, and the two first cooling assemblies 510 are respectively located on both sides of the middle wire 102 to cool the middle wire 102 on two opposite surfaces at the same time, thereby improving the cooling efficiency.
[0063] Of course, in other embodiments, the first cooling component 510 may not be provided, and the intermediate wire 102 after extrusion molding may be cooled by air cooling and then directly transferred to the heat preservation component 520 .
[0064] It should be noted that the drawing mechanism 600 is a drawing machine commonly used in the art, and the specific structure of the drawing machine is not described in detail in this embodiment. In this embodiment, the diameter of the finished wire 103 after drawing by the drawing mechanism 600 is 0.5 mm to 10 mm, preferably 3 mm. Among them, the drawing temperature is 100° to 230° (the intermediate wire 102 is air-cooled during the transmission from the insulation component 520 to the drawing mechanism 600), which belongs to the medium and low temperature drawing range of aluminum alloy wires, and the deformation of the drawing is 10% to 60%.
[0065] like Figure 1 As shown, the winding mechanism 300 includes a winding frame 310 and a winding wheel 320 rotatably disposed on the winding frame 310. The winding wheel 320 realizes the winding of the finished wire 103 by rotation. The structure is simple and easy to operate.
[0066] The aluminum alloy wire processing production line also includes an aging platform 700, and the winding mechanism 300 for winding the finished wire 103 can be transferred to the aging platform 700 to perform natural aging treatment on the finished wire 103 to obtain nano-precipitated phases of different scales, thereby improving the structural properties of the finished wire 103, and further improving the strength and conductivity of the finished wire 103. In this embodiment, the temperature of natural aging is less than 60°C, and the time of natural aging is 7 days to 30 days. Of course, this embodiment does not limit the time of natural aging, and the operator can adjust it according to actual processing requirements.
[0067] The aluminum alloy wire processing production line also includes a second cooling assembly 800, which is located between the drawing mechanism 600 and the winding mechanism 300 to cool the finished wire 103 after the drawing process. Among them, the specific structure and quantity of the second cooling assembly 800 are the same as the specific structure and quantity of the first cooling assembly 510, and the specific structure of the second cooling assembly 800 is not repeated in this embodiment. It should be noted that in this embodiment, the cooling time of the finished wire 103 by the second cooling assembly 800 is about 10s, which can reduce its temperature to 90°C to 100°C. Of course, this embodiment does not limit the cooling time of the finished wire 103 by the second cooling assembly 800, and the operator can adjust it according to actual processing requirements.
[0068] The aluminum alloy wire processing production line also includes an oil cleaning mechanism 900, which is located between the drawing mechanism 600 and the winding mechanism 300 (specifically, between the second cooling assembly 800 and the winding mechanism 300) to treat the oil on the finished wire 103, thereby ensuring its surface cleanliness. Specifically, the oil cleaning mechanism 900 includes a cleaning agent storage cylinder 910 and a nozzle 920, the cleaning agent storage cylinder 910 contains cleaning agent, the outlet of the nozzle 920 faces the finished wire 103, and the inlet of the nozzle 920 is connected to the outlet of the cleaning agent storage cylinder 910 to spray cleaning agent on the surface of the finished wire 103, thereby achieving the cleaning of the oil on its surface. Optionally, the number of the oil cleaning mechanism 900 is two, and the two oil cleaning mechanisms 900 are respectively located on both sides of the finished wire 103, so as to clean the two opposite surfaces of the finished wire 103 at the same time, thereby improving the cleaning efficiency.
[0069] Figure 2 FIG. 2 shows a flow chart of the aluminum alloy wire processing method provided in this embodiment. Figure 2 Combined with Figure 1 As shown, this embodiment also provides an aluminum alloy wire processing method, which includes the following steps:
[0070] Step S1: forming the aluminum alloy rod material 101 into an intermediate wire material 102 by using an extrusion process;
[0071] Step S2: Cooling and keeping the extruded intermediate wire 102 warm;
[0072] Step S3: The intermediate wire 102 after heat preservation is formed into a finished wire 103 by a drawing process, wherein the drawing temperature is 100° to 230°.
[0073] In the aluminum alloy wire processing method provided in the present embodiment, when the intermediate wire 102 is drawn, it is first cooled and kept warm. The insulation process can reduce the temperature difference between the center and the surface of the intermediate wire 102 to improve the uniformity of the internal structure of the finished wire 103. The cooled intermediate wire 102 can be drawn at a medium-low temperature in the range of 150° to 170°, which can not only refine the grain structure, but also simultaneously form a fine nano-precipitate phase through dynamic aging, thereby improving the strength and conductivity of the finished wire 103.
[0074] It can be understood that the extrusion process of the aluminum alloy rod 101 in step S1 can be implemented by the above-mentioned extrusion mechanism 400; the cooling and insulation of the extruded intermediate wire 102 in step S2 can be implemented by the above-mentioned temperature control mechanism 500; and the drawing process of the intermediate wire 102 in step S3 can be implemented by the above-mentioned drawing mechanism 600.
[0075] Before step S1, the method further includes:
[0076] Step S0: preparing an aluminum alloy rod material 101.
[0077] In this embodiment, the preparation process of the aluminum alloy rod material 101 is as follows: 1) pure aluminum ingots and intermediate alloy ingots are configured according to a preset alloy composition; 2) the configured pure aluminum ingots and intermediate alloy ingots are placed in a smelting furnace for melting and alloying; 3) the alloyed melt is subjected to boronization treatment; 4) the aluminum alloy melt is subjected to purification treatments such as degassing, impurity removal, slag removal, covering with a covering agent, and heat preservation and standing in the smelting furnace: 5) a degassing device and a ceramic filter device; 6) poured into a continuous casting machine and cast into the aluminum alloy rod material 101.
[0078] It should be noted that the aluminum alloy rod 101 needs to be subjected to homogenization heat treatment before extrusion to ensure the uniformity of its structure. In addition, the aluminum alloy rod 101 needs to be preheated to about 300° C. before being transferred to the extrusion mechanism 400, or directly transferred to the extrusion mechanism 400 at room temperature.
[0079] After step S3, the method further includes:
[0080] Step S4: Coiling the finished wire 103 and subjecting it to natural aging.
[0081] It is understandable that the operation of winding the finished wire 103 in step S4 can be implemented by the above-mentioned winding mechanism 300, and the winding mechanism 300 for winding the finished wire 103 can be placed on the aging platform 700 for natural aging to obtain nano-precipitated phases of different scales, thereby improving the structural properties of the finished wire 103, and further improving the strength and conductivity of the finished wire 103. In this embodiment, the natural aging time is 7 to 10 days.
[0082] Also included between step S3 and step S4:
[0083] Step S401: Cooling the finished wire 103.
[0084] It is understandable that the cooling process of the finished wire 103 in step S401 can be implemented by using the second cooling assembly 800 described above, and this embodiment will not elaborate on the cooling process.
[0085] Also included between step S401 and step S4:
[0086] Step S402: cleaning the cooled finished wire 103 from oil stains.
[0087] It is understandable that the oil cleaning process for the finished wire 103 in step S402 can be implemented by using the above-mentioned oil cleaning mechanism 900, and the oil cleaning process will not be described in detail in this embodiment.
[0088] The operator used the above aluminum alloy wire processing method to prepare two components of aluminum alloy wires. After experimental verification, the yield strength, tensile strength, elongation and conductivity of the two aluminum alloy wires were obtained, which were greatly improved compared with the preparation method in the prior art.
