DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] Based on the provided raw material ratio range, the raw material ratio is changed to manufacture aluminum alloy lamp poles, as follows:

[0039] Embodiment 1

[0040] A high thermal conductivity 6xxx series aluminum alloy lamp pole, comprising the following components: Mg: 0.73 wt%, Si: 0.63 wt%, Fe: 0.15 wt%, Mn: 0.05 wt%, total content of impurity elements Cr, Ti, V: 0.005 wt%, and the rest is Al.

[0041] A method for preparing a high thermal conductivity 6xxx series aluminum alloy lamp pole, specifically comprising the following steps:

[0042] S01. Prepare pure Al (≥99.7 wt%), pure Mg (≥99.9 wt%), Al-11Si, Al-13Ce, Al-2.2Sc, Al-20Y, and Al-4Zr master alloys, preheat them, and remove surface moisture.

[0043] S02, use a high-temperature induction melting furnace to heat up to 750℃ and put in pure Al to melt it. Then, perform slag removal at the same temperature to remove the slag. Then add pure Mg and other intermediate alloys in S01. Add a covering agent, which is a mixture of sodium chloride and potassium chloride in a ratio of 1:1. Keep warm for 10 minutes, wait for the alloy to be fully melted, and stir it thoroughly to ensure uniform composition. Then perform slag removal. Then add hexachloroethane for degassing and refining, and the amount added is 1% of the mass of the charge. Casting is performed after slag removal. The resulting alloy is poured into a copper mold and immediately placed in water at room temperature. The ingot size is 50mm in diameter. The actual chemical composition of the alloy is determined by an inductively coupled plasma emission spectrometer.

[0044] S03, homogenization treatment: heating to 450°C at a heating rate of 50°C / h and keeping the temperature for 4 hours, then heating to 550°C at a heating rate of 50°C / h and keeping the temperature for 6.5 hours. After the homogenization treatment, forced cooling is performed by a fan outside the furnace.

[0045] When extruding into round bars, the extrusion temperature needs to be controlled at 390°C. The alloy after homogenization is peeled and extruded into round bars with a diameter of 10 mm.

[0046] S04, aging treatment: the extruded alloy is solution treated at 510℃ for 1.5 hours. It is quenched in water at room temperature of 20℃. The artificial aging stage is a two-stage aging: the first aging temperature is 100℃, aging for 3 hours; the second aging temperature is 190℃, aging time for 2 hours.

[0047] The interval between each stage of solution treatment, quenching treatment and two-stage aging is less than 3 minutes. Quenching treatment should be carried out immediately after solution treatment, and then two-stage aging should be carried out immediately. The water quenching time is 2 minutes.

[0048] S05. The processed round bars are cut, bent, welded, repaired and polished to form lamp poles.

[0065] The detailed data of the comparative ingredients are as follows:

[0066] Hardness, tensile strength, elongation, thermal conductivity and pitting depth test table of the alloys of Examples 1 to 9

[0067] Hardness (HV) Tensile strength(MPa) Elongation(%) Thermal conductivity (W / m·k) Pitting depth (μm) Example 1 100.3 306.1 10.3 163 48.5 Example 2 109.1 323.2 10.6 185 45.2 Example 3 115.3 315.5 12.5 196 30.4 Example 4 124.2 330.5 11.9 201 39.8 Example 5 125.3 322.5 18.0 218 11.2 Example 6 128.8 325.6 13.5 209 35.5 Example 7 127.8 335.6 12.8 210 21.8 Example 8 129.3 340.0 19.5 229 17.6 Example 9 128.3 343.2 18.3 219 23.8

[0068] The pitting depth test process is as follows:

[0069] The polished samples were immersed in 3.5% NaCl solution for 4000s on a CH1660D electrochemical workstation for cyclic polarization curves. The scanning range of the polarization curve for pure Al was -1.2~0.4V, the scanning speed was 2 mV / s, and the number of scanning segments was 2. A three-electrode system was used, in which a saturated calomel electrode was used as the reference electrode and a graphite electrode was used as the auxiliary electrode. The characteristic points Ecorr, Epit, Eptp and Erp on the cyclic polarization curve were determined. The polished samples were polarized to the corresponding characteristic potentials, and then placed in a 2%CrO3 +5%H3PO4 solution at 80℃ for 5min to remove the corrosion products, and then washed with ethanol. The pitting morphology of the alloy was observed using a JSM-5610LV scanning electron microscope.

[0070] Based on the above table, it can be seen that when the Mg / Si mass ratio of the alloy is 1.53, the hardness, tensile strength, thermal conductivity and other performances of the aluminum alloy are better.

[0071] The amount of rare earth elements added in Example 3 and Example 8 is basically the same, and the difference is the Mg / Si mass ratio. Similarly, it can be found that when the Mg / Si mass ratio is 1.53, the various properties of the alloy are better. The Mg / Si mass ratio of the selected examples is 1.53.

[0072] It is found from the data in the table above that when different contents of rare earth elements (Ce, Sc and Y) are added, the various properties of the alloy are greatly increased, the thermal conductivity is increased by up to 38%, the pitting depth is reduced by up to 77%, the elongation is increased by up to 50%, and the tensile strength is increased by up to 11%. The Al-Mg-Si-Ce-Sc-Y alloy of Example 5 obtained after the Mg / Si mass ratio and the rare earth element alloying coordinated regulation has a thermal conductivity of 229 W / m·k, an elongation of 19.5%, a pitting depth of 17.6 μm, a tensile strength of 340MPa and a hardness of 129.3 HV. While the high thermal conductivity ensures that the alloy has excellent heat dissipation ability, it has stronger corrosion resistance and can cope with the changeable environmental problems in nature. At the same time, its high elongation ensures that the alloy has the characteristics of easy processing and forming.

[0073] The thermal conductivity of the alloys with added Sc element (Examples 5, 8, and 9) is higher than that of other alloys. The study found that in the B' phase, Sc atoms occupy the position of Si atoms in the B' phase, resulting in the B' phase with Sc atoms having higher thermal stability. At the same time, the high-density B' phase in the Sc-containing alloy can improve the strength and hardness of the alloy. In addition, the β" phase can nucleate and grow around small-sized Al3Sc particles. β' and U2 phases can also be formed around large-sized Al3Sc particles, which can enable the alloy to maintain high hardness and thermal conductivity after long-term aging. The high-density β" phase can improve the hardness and strength of the alloy, but it is easy to cause pitting corrosion in the alloy. The alloy with added Ce element makes the β" phase coarsened to a certain extent, increases its cross-sectional area and length, thereby slightly reducing the density of the β" phase and reducing the occurrence of alloy pitting corrosion. The alloy with added Y element can also achieve this effect. It can be found that Al-Mg-Si-Ce-Y alloy has stronger pitting resistance than Al-Mg-Si-Ce alloy. The combined regulation of the three elements Ce, Sc and Y enables the alloy to have stronger thermal conductivity and corrosion resistance, while also having better strength and elongation.

[0074] In summary, when the Mg / Si mass ratio is 1.53, the alloy can achieve better performance, and adding rare earth elements (Ce, Sc, Y) can also make the alloy obtain more performance. The present invention controls the Mg / Si mass ratio and adds rare earth elements to jointly regulate and control, and finds a high thermal conductivity 6xxx series aluminum alloy, whose performance is 129.3HV at room temperature, ultimate tensile strength is 340MPa, elongation is 18%, thermal conductivity is 229 W / m·k, and pitting is reduced by 62% compared with Al-Mg-Si alloy.

[0075] In the above technical scheme, the heat dissipation capacity and corrosion resistance of the alloy are improved by adding rare earth elements. It has the characteristics of high heat dissipation capacity, high strength, corrosion resistance, easy processing and low cost. While ensuring that it meets the basic strength requirements, it better improves its heat dissipation capacity and has excellent corrosion resistance, which is sufficient to cope with the changing natural environment and adapt to lamp poles exposed to the natural environment.

[0076] Embodiment 10

[0077] like Figure 1-9 As shown, a high thermal conductivity 6xxx series aluminum alloy lamp pole preparation device includes an induction furnace crucible 2 and a rotating slag cleaning scraper 1, the rotating slag cleaning scraper 1 includes a fixed sleeve 12 and a rotating shaft 11, a slag collecting basket 13 is arranged on the rotating shaft 11, and a rotating core mechanism 3 is arranged on the fixed sleeve 12. The rotating core mechanism 3 includes a toggle scraper 32 obliquely arranged on the fixed sleeve 12 in a circular array, and the end of the toggle scraper 32 rotates and reciprocates with the rotating shaft 11 to toggle the slag to gather to the slag collecting basket 13.

[0078] Specifically, the rotating slag cleaning shovel 1 is fixed to the mobile end of the manipulator, or to the profile frame (the bracket is made of aluminum alloy). After the metal solution in the crucible 2 of the induction furnace is heated, a layer of slag is formed on the liquid surface. The slag collecting basket 13 is rotatably connected to the rotating shaft 11, and the other end of the rotating shaft 11 is fixedly connected to the output end of the motor through a coupling. When collecting slag, first, the moving shovel 32 is brought close to the liquid surface and the rotating shaft 11 is started to drive the ends of the multiple moving shovels 32 to reciprocate with the rotation of the rotating shaft 11 to move the slag on the liquid surface and push the slag against the slag collecting basket 13 in the center of the liquid surface, and then the whole rotating slag cleaning shovel 1 is lifted up to collect the slag through the slag collecting basket 13.

[0079] In the above technical solution, compared with cleaning from one side of the induction furnace crucible 2 to the other side, the method of moving the liquid toward the center can prevent the slag from contacting the side wall of the induction furnace crucible 2, thereby preventing the slag from condensing on the side wall, and can keep the side free of molten impurities when the remaining metal is added to increase the liquid level, thereby improving the overall purity.

[0080] As an embodiment provided by the present invention, a fixing plate 14 is provided on the fixing sleeve 12 , and fitting blades 30 are symmetrically provided on the fixing plate 14 , and the moving lever 32 reciprocates between the two fitting blades 30 .

[0081] Specifically, the fixed sleeve 12 is provided with a fixed shell 121, the fixed plate 14 is provided on the fixed shell 121, and the moving pick 32 is movably provided in a movable groove 141 opened on the fixed plate 14. When the moving pick 32 reciprocates, the fixed plate 14 is extended to gather the scum on the liquid surface. The reciprocating motion includes two steps of extending and retracting. When extending, the moving pick 32 is extended along the two bonding blades 30 to be restricted from moving the liquid surface. When retracting, due to the bonding of the two bonding blades 30, the scum attached to the moving pick 32 will be scraped off, thereby playing a cleaning role.

[0082] When collecting slag, firstly, the moving shovel 32 is brought close to the liquid surface and the rotating shaft 11 is started to drive the ends of the multiple moving shovels 32 to reciprocate with the rotation of the rotating shaft 11 to move the slag on the liquid surface and push the slag to the slag collection basket 13 at the center of the liquid surface. While the moving shovel 32 reciprocates, the two fitting blades 30 always fit the moving shovel 32 to clean the slag attached to the moving shovel 32, and limit the moving shovel 32 so that it is restricted when extending and swings to move the liquid surface, and then the slag cleaning shovel 1 is rotated as a whole to be lifted up to collect the slag through the slag collection basket 13.

[0083] As an embodiment provided by the present invention, a rotating disk 31 is rotatably connected to the fixed plate 14 , and a shifting pick 32 is rotatably connected to the rotating disk 31 . The shifting pick 32 reciprocates along the laminating blade 30 as the rotating disk 31 rotates.

[0084] Specifically, the rotating disk 31 is rotatably connected to the movable groove 141, and the start end of the moving lever 32 is rotatably connected to the rotating disk 31 (with Figure 6 For reference, the starting end is the upper end and the ending end is the lower end). When it is necessary to drive the tossing pick 32 to move back and forth, the rotating disk 31 will rotate to drive the starting end of the tossing pick 32 to rotate in a circle. Because the tossing pick 32 is restricted by the bonding blade 30, the end of the tossing pick 32 will perform a telescopic reciprocating motion while swinging left and right to achieve the stirring of the liquid surface. One of the bonding blades 30 is fixed to one side of the tossing pick 32 by a movable spring plate 301, and the other bonding blade 30 is fixed to the other side of the tossing pick 32 by a substrate 302. When removing scum on the tossing pick 32, the movable spring plate 301 cooperates with the substrate 302 to realize elastic pressure on the bonding blade 30, so that when the scum is thickened, the movable spring plate 301 is bent to increase the pressure for cleaning.

[0085] When collecting slag, firstly, the moving shovel 32 is brought close to the liquid surface and the rotating shaft 11 is started to drive the rotating disk 31 to rotate, so that the ends of the multiple moving shovels 32 rotate with the rotating shaft 11 to reciprocate to move the scum on the liquid surface and push the scum to the slag collection basket 13 at the center of the liquid surface. While the moving shovel 32 reciprocates, the two fitting blades 30 always fit the moving shovel 32 to clean the scum attached to the moving shovel 32, and limit the moving shovel 32 so that it is restricted when the moving shovel 32 extends and swings to move the liquid surface, and then the slag cleaning shovel 1 is rotated as a whole to be lifted up to collect the scum through the slag collection basket 13.

[0086] As an embodiment provided by the present invention, a conical shaft 10 is arranged on the rotating shaft 11, a fixing frame 42 is rotatably connected to the fixing plate 14, a driving plate 41 slidably connected to the fixing frame 42 and slidably connected to the conical shaft 10, an elastic push member 411 is arranged on the driving plate 41, and the driving plate 41 rotates with the rotating shaft 11 to drive the elastic push member 411 to push the rotating disk 31 to rotate.

[0087] Specifically, a conical shaft 10 is provided on the rotating shaft 11, and the slag collecting basket 13 is rotatably connected to the conical shaft 10. A chute 101 is provided on the conical shaft 10, and a driving plate 41 is slidably connected to the chute 101. The fixing frame 42 is rotatably connected to the fixing plate 14. When the rotating shaft 11 rotates, the driving plate 41 rotates with the conical shaft 10, so that the elastic push member 411 on the driving plate 41 moves, so that the elastic push member 411 is attached to the side of the rotating disk 31, and the elastic push member 411 begins to bend as the driving plate 41 rotates. The push piece 411 is used to make the elastic push piece 411 fit the rotating disk 31 to drive the rotating disk 31. There are multiple driving plates 41, so that the rotating disk 31 is fit to multiple driving plates 41 and rotates with them, and the rotating disk 31 is driven to rotate intermittently in sequence, resulting in the reciprocating motion of the paddle 32 to be intermittent, so as to reduce the fluctuation of the liquid level, thereby preventing the scum from spreading due to the fluctuation. A second spring 412 is provided between the driving plate 41 and the fixed shell 121, and the second spring 412 is used to push the driving plate 41 to fit the tapered shaft 10.

[0088] When collecting slag, firstly, the moving shovel 32 is brought close to the liquid surface and the rotating shaft 11 is started, so that the driving plate 41 rotates with the rotation of the conical shaft 10, and the elastic push member 411 is pressed against the rotating disk 31 to rotate, so that the ends of the multiple moving shovels 32 rotate with the rotating shaft 11 to reciprocate, so as to move the scum on the liquid surface and push the scum against the slag collection basket 13 at the center of the liquid surface. While the moving shovel 32 reciprocates, the two pressing blades 30 always press against the moving shovel 32 to clean the scum attached to the moving shovel 32, and limit the moving shovel 32 so that it is restricted when the moving shovel 32 is extended and swings to move the liquid surface, and then the slag cleaning shovel 1 is rotated as a whole to be lifted up to collect the scum through the slag collection basket 13.

[0089] As an embodiment provided by the present invention, the shifting lever 32 is assembled at the following two stations:

[0090] First station: the lever 32 moves back and forth as the rotating disk 31 rotates;

[0091] Second station: The rotating disk 31 is locked to keep the moving lever 32 in an inclined state.

[0092] Specifically, when the rotating shaft 11 drives the rotating disk 31 to rotate so that the moving shovel 32 performs reciprocating motion, the moving shovel 32 is in the first position, at which time the scum is gathered. When the scum is gathered and needs to be salvaged, the moving shovel 32 is switched to the second position so that the moving shovel 32 remains in an inclined state to rotate the entire rotating slag cleaning shovel 1, so that the inclined moving shovel 32 can also catch the excess scum overflowing from the slag collection basket 13.

[0093] When collecting slag, firstly, the shovel 32 is brought close to the liquid surface and the rotating shaft 11 is started, so that the driving plate 41 rotates with the rotation of the conical shaft 10, and the elastic push member 411 is pressed against the rotating disk 31 to rotate, so that the ends of the multiple shovel shovels 32 rotate with the rotating shaft 11 to reciprocate, so as to stir the scum on the liquid surface and push the scum against the slag collection basket 13 at the center of the liquid surface. While the shovel shovel 32 reciprocates, the two pressing blades 30 always press against the shovel shovel 32 to clean the scum attached to the shovel shovel 32, and limit the shovel shovel 32 so that it is restricted when the shovel shovel 32 is extended and swings to stir the liquid surface, and then the slag cleaning shovel 1 is rotated as a whole to be lifted up to collect the scum through the slag collection basket 13. Before lifting the rotating shaft 11, the shovel shovel 32 is switched to the second station to catch the excess scum overflowing from the slag collection basket 13.

[0094] As an embodiment provided by the present invention, a sliding lock block 33 and a locking rod 34 are slidably connected to the fixed plate 14 , and the locking rod 34 moves with the pushing of the tapered shaft 10 to drive the sliding lock block 33 to move and lock the toggle lever 32 .

[0095] Specifically, a sliding lock block 33 is slidably connected to the movable groove 141, and a first spring 331 is arranged therebetween. A drive lock column 341 is arranged in a linear array on the locking rod 34, and the drive lock column 341 is located in the movable groove 141. The tapered shaft 10 can be driven to slide along the axial direction of the fixed sleeve 12, so that the large end of the tapered shaft 10 is pushed against the locking rod 34, so as to push the sliding lock block 33 close to the rotating disk 31 through the drive lock column 341, and the starting end of the driving lever 32 has a protruding cylinder, and the sliding lock block 33 will push and fit the protruding cylinder to lock the protruding cylinder to the position of the sliding lock block 33.

[0096] When collecting slag, firstly, the shovel 32 is brought close to the liquid surface and the rotating shaft 11 is started, so that the driving plate 41 rotates with the rotation of the conical shaft 10, and the elastic push member 411 is pressed against the rotating disk 31 to rotate, so that the ends of the plurality of shovels 32 reciprocate with the rotation of the rotating shaft 11 to stir the scum on the liquid surface and push the scum against the slag collection basket 13 at the center of the liquid surface. While the shovel 32 reciprocates, the two pressing blades 30 are always pressed against the shovel 32 to clean the scum attached to the shovel The slag on the slag collecting basket 13 is removed, and the tossing shovel 32 is restricted so that the tossing shovel 32 is restricted when extending and swings to toss the liquid surface. Then, after the convergence is completed, the rotating shaft 11 is driven to move along the axis, so that the slag collecting basket 13 and the tapered shaft 10 move downward to perform the slag collecting operation. The locking column 341 pushes the sliding lock block 33 close to the rotating disk 31 to switch the tossing shovel 32 to the second station to catch the excess slag overflowing from the slag collecting basket 13 and the overall rotating slag cleaning shovel 1 is lifted to collect the slag through the slag collecting basket 13.

[0097] As the optimal embodiment provided by the present invention, the rotating shaft 11 is driven to rotate to drive the prying lever 32 to vibrate at the second workstation. A knocking column 35 is provided on the fixed plate 14, and the second end of the knocking column 35 is facing the adjacent rotating disk 31. The driving plate 41 moves with the conical shaft 10 to make the elastic pushing member 411 bend along the rotating disk 31 and rebound to knock the first end of the knocking column 35.

[0098] Specifically, when the tapered shaft 10 sinks and moves, the driving plate 41 will slide along the limiting groove 421 provided on the fixing frame 42 as the large end of the tapered shaft 10 sinks, thereby changing the position of the elastic push member 411. The rotating disk 31 is provided with a large end. When the position of the elastic push member 411 moves, it will bend along the large end to push and bend the elastic push member 411 so that the elastic push member 411 bends to store energy. The fixing plate 14 is provided with a knocking column 35. When the elastic push member 411 accumulates energy with the rotation and passes over the large end of the rotating disk 31, it will rebound so as to knock the first end of the knocking column 35 (with the elastic push member 411) through the elastic push member 411. Figure 6 For reference, the first section is the lower end and the second end is the upper end), so as to generate vibration in the rotary slag cleaning shovel 1, so as to utilize the vibration generated to shake off the liquid remaining on the slag after the slag collection is completed.

[0099] When collecting slag, firstly, the shovel 32 is brought close to the liquid surface and the rotating shaft 11 is started, so that the driving plate 41 rotates with the rotation of the conical shaft 10, and the elastic push member 411 is pressed against the rotating disk 31 to rotate, so that the ends of the plurality of shovels 32 reciprocate with the rotation of the rotating shaft 11 to stir the scum on the liquid surface and push the scum against the slag collection basket 13 at the center of the liquid surface. While the shovel 32 reciprocates, the two pressing blades 30 always press against the shovel 32 to clean the scum attached to the shovel 32, and limit the shovel 32 so that it is restricted when the shovel 32 is extended. The liquid surface is swung and moved, and then after the convergence is completed, the rotating shaft 11 is driven to move along the axis, so that the slag collecting basket 13 and the tapered shaft 10 move downward to perform the slag collecting operation. The locking column 341 is driven to push the sliding lock block 33 close to the rotating disk 31 to switch the moving paddle 32 to the second station to catch the excess slag overflowing from the slag collecting basket 13. The entire slag cleaning paddle 1 is rotated and lifted up to collect the floating slag through the slag collecting basket 13. After the slag is collected, the rotating shaft 11 rotates to make the elastic pushing member 411 store energy with the rotation and pass over the rotating disk 31 to knock on the first end of the knocking column 35 to generate vibration, so as to drain the slag that has been picked up.
