Description

Technical Field

[0001] The invention belongs to the technical field of aluminum alloy material processing, in particular to a polishing device for aluminum alloy material. Background Art

[0002] Aluminum alloy door frames usually need to be polished during the processing and production process. At present, polishing usually adopts the method of polishing with a polishing disc. Aluminum alloy usually has good heat resistance, but in the polishing process, the accumulation of local heat will have an adverse effect on its surface and performance. During the polishing process, friction will generate heat, especially under high speed and high pressure conditions. This local overheating will cause thermal deformation or softening of the aluminum alloy surface, affecting the polishing effect. The local temperature increase during the polishing process will cause the material to soften, thereby reducing its strength and hardness, affecting the surface finish and overall performance. The accumulation of heat may change the characteristics of the oxide layer on the surface of the aluminum alloy, resulting in inconsistent polishing effects, and may even cause new oxidation phenomena. The use of traditional water cooling will cause the polishing coolant to mix with the polishing agent, and the polishing agent will be diluted by water, which will reduce the polishing effect. At the same time, a large amount of polishing agent will be lost along with the flushing of the polishing coolant, and frequent addition of polishing agent is required, which reduces the polishing efficiency and increases the cost of polishing.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention is provided with an air cooling mechanism and a water cooling mechanism. Due to the operation of the air cooler, the outside air can be sucked through the air suction box and the air suction pipe, and the air can be converted into cold air and sent to the inside of the three-flow pipe through the air outlet pipe 1, and the air can be diverted by the three-flow pipe, so that part of the cold air passes through the air outlet head 1 to the polishing wheel to cool down the polishing part of the aluminum alloy material, thereby achieving the effect of air cooling and heat dissipation. The rest of the cold air inside the three-flow pipe will be blown out through the air outlet head 2 and discharged to the outside through the air hole. Due to the operation of the water pump, the water inside the water tank can be sucked by the water pump and sent to Inside the water outlet pipe, the water passes through the heat conductor and takes away the heat from the heat conductor. Then, the water cross section is cut and flows downstream in a spraying manner through the temperature sensor element. In the downstream process, the cold air blown out by the second air outlet head takes away the heat of the spraying water flow. Finally, the water flows down to the inside of the water tank for continued extraction by the water pump, thereby achieving the effect of indirect water cooling and heat dissipation. This design achieves efficient heat dissipation through air cooling and indirect water cooling. This heat dissipation method can avoid the dilution and loss of the polishing agent by the water body, thereby improving the polishing efficiency.

[0021] 2. The present invention provides a spray mechanism. Due to the movement of the cover 1, the connecting rod 1 can be driven to move in the opposite direction of the connecting block 2, and the piston, spring 3 and air cylinder can be driven to move and generate a high-velocity airflow through the nozzle. Due to the Bernoulli principle, the sealing ball can be pushed open by the high pressure, and the water inside the water tank can be sucked into the upper part of the sealing ball inside the connecting pipe. Due to the reset of the cover 1, the water outlet pipe is pressurized toward the inside of the sleeve. Due to the reset movement of the cover 1, the connecting rod 1, the moving block and the piston can be driven to move and reset through the connecting block 1. The water inside the connecting pipe can be pressed out by the Bernoulli principle through the exhaust of the air cylinder, and the water inside the connecting pipe can be dispersed by the high-velocity airflow. Water mist is formed and sprayed out from the nozzle. After the piston is reset, the nozzle will stop spraying. At this time, the air pressure inside the sleeve rises again to a level greater than the elastic force of spring one, so that the sleeve is pushed again, and the air outlet pipe two releases high-pressure gas again, and applies pressure to the water mist diffused in the air, accelerating the water mist to sink to the polishing part of the aluminum alloy material, so as to improve the cooling intensity by utilizing the principle of heat absorption by evaporation of water mist, without causing dilution and loss of the polishing agent, and at the same time utilizing the reciprocating alternating operation of the air outlet pipe two and the nozzle to form a method of spraying water mist and then discharging air to further increase the cooling height, thereby achieving a high-intensity cooling effect in order to cope with the occurrence of high heat conditions.

[0022] 3. The present invention provides a scraper block and a round rod. Due to the movement of the movable frame, the fixed rod, the movable plate and the round rod can be driven to move together. As the round rod moves, the scraper block scrapes the waste on the air filter plate to the inside of the collection box, thereby cleaning the waste on the air filter plate and avoiding long-term accumulation of waste on the air filter plate to affect the suction force of the air cooler. Since the movable frame will only move when encountering a rough weld, and each side of the aluminum alloy door frame has one or two welds, the scraper block can clean the air filter plate once or twice when polishing each side, thereby further ensuring the filtration efficiency of the air filter plate and preventing the air filter plate from being blocked.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 17 As shown, the present invention provides a polishing device for aluminum alloy material, comprising a polishing table 1, a polishing mechanism 2, a water storage mechanism 3, an air cooling mechanism 4 and a water cooling mechanism 5;

[0043] The polishing mechanism 2 is arranged on the polishing table 1, the water storage mechanism 3 is arranged on the polishing table 1, the air cooling mechanism 4 is arranged on the water storage mechanism 3, and the water cooling mechanism 5 is arranged on the water storage mechanism 3;

[0044] The water storage mechanism 3 includes a mounting frame 31, which is mounted on the polishing table 1. The interior of the mounting frame 31 is mounted on a water tank 32, and a plurality of air holes 33 are opened on one side of the water tank 32.

[0045] The air cooling mechanism 4 includes an air cooler 41, which is installed on the water storage mechanism 3. The top of the air cooler 41 is connected to an air outlet pipe 1 42, and the other end of the air outlet pipe 1 42 is connected to a three-flow pipe 43, and the central end of the three-flow pipe 43 is connected to an air outlet head 1 44. The bottom of the air cooler 41 is connected to an exhaust pipe 45, and an exhaust box 46 is installed on the polishing table 1. The other end of the exhaust pipe 45 is connected to the exhaust box 46, and an air filter plate 47 is installed inside the exhaust box 46. The inside of the water tank 32 contains water, and the inside of the water tank 32 is installed with an air outlet head 2 415 located above the water body, and the air outlet end of the air outlet head 2 415 faces the air hole 33, and the two side ends of the three-flow pipe 43 are connected to the air outlet head 2 415;

[0046] The water cooling mechanism 5 includes a water pump 51, which is installed on the water tank 32 and connected thereto. The water outlet end of the water pump 51 is connected to a water outlet pipe 52, and the other end of the water outlet pipe 52 is connected to a water spray plate 53 facing the inside of the water tank 32. The water spray plate 53 is located between the air outlet head 415 and the air hole 33. A heat conductor 54 is provided inside the water outlet pipe 52. The heat conductor 54 extends to the top of the water outlet pipe 52 and can contact the back side of the polished part of the aluminum alloy material. A temperature sensor element 55 that can monitor the temperature of the heat conductor 54 is installed on the water outlet pipe 52.

[0047] The above scheme is adopted: due to the operation of the air cooler 41, the outside air can be sucked through the exhaust box 46 and the exhaust pipe 45, and the air is converted into cold air and sent to the inside of the three-flow pipe 43 through the outlet pipe 1 42, and is diverted by the three-flow pipe 43, so that part of the cold air passes through the outlet head 1 44 to the polishing part of the polishing wheel 23 to cool down the polishing of the aluminum alloy material, thereby achieving the effect of air cooling and heat dissipation, and the rest of the cold air in the three-flow pipe 43 will be blown out through the outlet head 2 415 and discharged into the outside through the air hole 33. The operation of 51 can pump the water inside the water tank 32 through the water pump 51, and send the water to the inside of the water outlet pipe 52, pass through the heat conductor 54 through the water outlet pipe 52, and take away the heat on the heat conductor 54, and then the water cross section is cut and flowed downstream in a spraying manner through the temperature sensor element 55. During the downstream process, the cold air blown out by the air outlet head 415 takes away the heat of the spraying water flow, and finally the water flows down to the inside of the water tank 32, so that the water pump 51 continues to extract, thereby achieving the effect of indirect water cooling and heat dissipation.

[0048] like Figures 8 to 10 , Fig.12 and Fig.15 As shown, two spray mechanisms 6 are also included, and the two spray mechanisms 6 are respectively installed on both sides of the mounting frame 31. The spray mechanism 6 includes a fixed frame 617, and the fixed frame 617 is installed on the mounting frame 31. The fixed frame 617 is internally fixedly sleeved with a nozzle 618, one end of the nozzle 618 is connected to a nozzle 619, and the other end of the nozzle 618 is connected to an air cylinder 620. The air cylinder 620 is internally sleeved with a piston 621, and the piston 621 is internally movably sleeved with a connecting rod 624, one end of the connecting rod 624 extends to the outside of the air cylinder 620 and is connected to a connecting block 625, and the outside of the air cylinder 620 is fixedly sleeved with a moving block 622 located inside the air cylinder 620, a spring 3 623 located outside the connecting rod 624 is connected between the moving block 622 and the piston 621, and the other side of the connecting block 625 is connected to a movable frame 626.

[0049] Adopting the above scheme: connecting block 1 625 drives connecting rod 1 624 and moving block 622 to move inward, and at the same time spring 3 623 is compressed. Due to the elastic recovery effect of spring 3 623, piston 621 can be pushed to move and reset. At this time, the gas inside the cylinder 620 can be quickly discharged through the nozzle 618 and the nozzle 619, and the Bernoulli principle will be used to press out the water inside the connecting pipe 636, and the high airflow will disperse to form water mist and spray it from the nozzle 619. After the piston 621 is reset, the nozzle 619 will stop spraying.

[0050] like Fig.10 and Fig.11As shown, two spray mechanisms 6 are also included, and the two spray mechanisms 6 are respectively installed on both sides of the mounting frame 31. The spray mechanism 6 also includes a fixing frame 61, and the fixing frame 61 is installed on the mounting frame 31. A fixing cylinder 62 is installed on the upper part of the fixing frame 61. The interior of the fixing cylinder 62 is fixedly sleeved with a sleeve 63, and the exterior of the sleeve 63 is movably sleeved with a cover 64. A group of circular holes 65 are opened around the cover 64. A spring 2 610 is connected to one side of the cover 64, and the other end of the spring 2 610 is connected to the fixing cylinder 62. One side of the fixing cylinder 62 is connected to an outlet pipe 2 611 facing the polishing part of the aluminum alloy material. The front and rear of the other side of the cover 64 are connected to a mounting rod 628, and the other end of the mounting rod 628 extends to the outside of the fixing cylinder 62 and is fixedly connected to a connecting block 2 629 located outside the sleeve 63.

[0051] By adopting the above scheme: as the air is delivered by the water outlet pipe 52, the air pressure inside the sleeve 63 can be gradually increased. When the air pressure inside the sleeve 63 is released, the high pressure inside the sleeve 63 will quickly push the cover 64 to move. Due to the movement of the cover 64, the circular hole 65 can be connected with the sleeve 63, so that the high-pressure gas inside the sleeve 63 is quickly discharged into the interior of the limit rail 66 through the circular hole 65, and finally sprayed downward through the air outlet pipe 2 611.

[0052] like Figure 2 , Figure 3 , Fig.10 , Fig.14 , Fig.16 and Fig.17 As shown, one end of the sleeve 63 extends to the outside of the fixed cylinder 62 and a sleeve cover 612 is sleeved at the port, the outer side of the sleeve cover 612 is connected with a connecting pipe 613, the other end of the connecting pipe 613 is sleeved with a movable sleeve 614, the temporal movable sleeve of the movable sleeve 614 is connected with a bent pipe 615, one end of the bent pipe 615 is sealed and the other end is connected to the air outlet pipe 42, a through hole 616 sealed by the movable sleeve 614 is opened on the outside of the bent pipe 615, an electric telescopic rod 634 is installed on the outside of the air outlet pipe 42, the other end of the electric telescopic rod 634 is connected with a fixed plate 635, and the fixed plate 635 is connected to the movable sleeve 614.

[0053] The above scheme is adopted: the electric telescopic rod 634 pushes the fixed plate 635 to move, and drives the movable sleeve 614, the connecting pipe 613 and the sleeve cover 612 to move, so that the through hole 616 is connected to the movable sleeve 614. At this time, a part of the gas transported inside the water outlet pipe 52 will be transported to the inside of the sleeve 63 through the bent pipe 615, the through hole 616, the connecting pipe 613 and the sleeve cover 612, and the gas is compressed into the inside of the sleeve 63, so that gas can be supplied to the sleeve 63.

[0054] like Fig.10 and Fig.11As shown, four limit rails 66 are installed around the inside of the fixed cylinder 62, and four sliders 67 that can slide inside the limit rails 66 are installed around the outside of the cover 64. The internal movable sleeve of the slider 67 is provided with a hemispherical clamping block 68, and the hemisphere of the hemispherical clamping block 68 is clamped in the inside of the limit rails 66. The other side of the hemispherical clamping block 68 is connected to a spring 69, and the other end of the spring 69 is connected to the slider 67.

[0055] With the above solution, when the air pressure inside the sleeve 63 is greater than the elastic force of the spring 1 69, the high pressure inside the sleeve 63 will quickly push the cover 1 64 to move. At this time, the spring 2 610 is compressed, and the hemispherical block 68 is separated from the limit rail 66. The spring 1 69 is compressed, so that the fixing effect of the cover 1 64 can be released. 10 and 11

[0056] like Fig.10 and Fig.13 As shown, the nozzle 618 is connected to a connecting pipe 636 installed inside the mounting frame 31 below, a stop seat 638 is fixedly sleeved in the center inside the connecting pipe 636, a stop block 637 located above the stop seat 638 is installed inside the connecting pipe 636, a spring four 640 is connected to the inner wall of the stop block 637, and the other end of the spring four 640 is connected to a sealing ball 639 that can abut the sealing stop seat 638.

[0057] The above scheme is adopted: when the circular shaft 2 633, the connecting block 1 625, the movable frame 626 and the connecting rod 1 624 move outward, the piston 621, the spring 3 623 and the air cylinder 620 are driven to move and the air is sucked through the nozzle 619. At this time, a high-velocity airflow will be generated inside the nozzle 618. Due to the Burruli principle, the sealing ball 639 can be pushed open by the high pressure. At this time, the spring 4 640 is compressed, releasing the seal of the connecting pipe 636 by the seat 638, and the water inside the water tank 32 is sucked into the upper part of the sealing ball 639 inside the connecting pipe 636.

[0058] like Figure 8 and Fig. 9 As shown, a connecting frame 630 is installed on the second fixing frame 617, a movable arm 631 is movably installed on the connecting frame 630, a circular shaft 1 632 that moves inside the movable arm 631 is connected to the second connecting block 629, and a circular shaft 2 633 that moves inside the movable arm 631 is connected to the second circular shaft 633.

[0059] By adopting the above scheme: due to the movement of the cover 1 64, the installation rod 628 can drive the connecting block 2 629 and the circular shaft 1 632 to move together and make the movable arm 631 swing; due to the swing of the movable arm 631, the circular shaft 2 633, the connecting block 1 625, the movable frame 626 and the connecting rod 1 624 can be driven to move in the opposite direction of the connecting block 2 629, and the piston 621, the spring 3 623 and the air cylinder 620 can be driven to move and air can be pumped through the nozzle 619, so that the connecting block 1 625 can be driven to move in the opposite direction when the connecting block 2 629 moves.

[0060] like Figure 2 , Figure 5 and Figure 8 As shown, movable grooves 416 are opened on both sides of the interior of the polishing table 1, and a movable plate 414 is slidably installed inside the movable groove 416. A round rod 413 is connected to the top of one side of the movable plate 414. The other end of the round rod 413 extends to the interior of the vacuum box 46 and is connected to a scraper block 412 that abuts against the air filter plate 47. A fixed rod 627 is connected to the top of one side of the movable plate 414, and the other end of the fixed rod 627 is connected to the movable frame 626.

[0061] The above scheme is adopted: due to the movement of the movable frame 626, the fixed rod 627, the movable plate 414 and the round rod 413 can be driven to move together. As the round rod 413 moves, the scraps on the air filter plate 47 are scraped to the inside of the collection box 48 through the scraper block 412, thereby cleaning the scraps on the air filter plate 47 and avoiding the long-term accumulation of scraps on the air filter plate 47 to affect the suction force of the air cooler 41.

[0062] like Figure 2 , Figure 5 and Figure 8 As shown, the internal movable sleeve of the vacuum box 46 is provided with a collection box 48 on one side of the air filter plate 47, the bottom of the collection box 48 is connected to a holder 410 located outside the vacuum box 46, the bottom of the polishing table 1 is connected to a fixed seat 49, and the internal movable sleeve of the fixed seat 49 is connected with a clamping plate 411 that can be clamped in the clamping seat 410.

[0063] By adopting the above solution: the clamping plate 411 is pulled out from the inside of the clamping seat 410, the fixing effect of the fixing seat 49 and the clamping seat 410 can be released. At this time, the collection box 48 can be taken out from the inside of the vacuum box 46, and the waste collected in the vacuum box 46 can be cleaned.

[0064] like Figure 2 As shown, the polishing mechanism 2 includes a bracket 21, which is mounted on the polishing table 1. A power motor 22 is mounted on the bracket 21, and the power motor 22 is connected to a polishing wheel 23 through a rotating shaft drive.

[0065] With the above solution, due to the operation of the power motor 22 , the power motor 22 can drive the polishing wheel 23 to rotate, and the polishing wheel 23 carrying the polishing agent is polished.

[0066] The working principle and use process of the present invention:

[0067] When in use, the door frame made of aluminum alloy is placed on the polishing table 1 so that the aluminum alloy material abuts against the polishing wheel 23. Due to the operation of the power motor 22, the power motor 22 can drive the polishing wheel 23 to rotate and be polished by the polishing wheel 23 carrying the polishing agent.

[0068] During the polishing process of the polishing wheel 23, since the heat-conducting member 54 is in contact with the polishing back side of the aluminum alloy material, the polishing heat above the aluminum alloy material can be conducted to the heat-conducting member 54, and the air cooler 41 and the water pump 51 are running at the same time. Due to the operation of the air cooler 41, the outside air can be sucked in through the exhaust box 46 and the exhaust pipe 45, and converted into cold air and sent to the inside of the three-flow pipe 43 through the outlet pipe 42, and is diverted by the three-flow pipe 43, so that part of the cold air passes through the outlet head 44 to cool down the polishing part of the aluminum alloy material of the polishing wheel 23, and at the same time, the aluminum alloy waste chips blown up by the outlet head 44 are sent to the inside of the exhaust box 46 by the suction force of the exhaust box 46, and are filtered by the air filter plate 47. Blocking and collecting, the effect of air cooling and heat dissipation can be achieved. The remaining cold air inside the three-flow tube 43 will be blown out through the air outlet head 415 and discharged into the outside through the air hole 33. Due to the operation of the water pump 51, the water inside the water tank 32 can be sucked by the water pump 51, and the water can be sent to the inside of the water outlet pipe 52, and the water passes through the heat conductor 54 through the water outlet pipe 52, and takes away the heat on the heat conductor 54. Then, the water cross-section is cut and flowed downstream in a spraying manner through the temperature sensor element 55. In the process of downstream, the cold air blown out by the air outlet head 415 takes away the heat of the spraying water flow, and finally the water flows down to the inside of the water tank 32, so that the water pump 51 can continue to extract, thereby achieving the effect of indirect water cooling and heat dissipation.

[0069] Due to the different glossiness of the aluminum alloy surface, and the fact that the welding point on the aluminum alloy surface is particularly rough, when polishing this area, in order to ensure the consistency of glossiness, the polishing time of this area will be longer. As the polishing time increases, the heat generated by the friction will also increase. At this time, the heat generated by the polishing operation will be higher than the heat generated during normal polishing, causing the heat conducted by the heat conductor 54 to increase and be monitored by the temperature sensor element 55. The air cooler 41 is driven by the control end to increase the wind force. At the same time, the electric telescopic rod 634 pushes the fixed plate 635 to move, and drives the movable sleeve 614, the connecting pipe 613 and the cover 612 to move, so that the through hole 616 is connected to the movable sleeve 614. At this time, the air transported inside the water outlet pipe 52 is The gas in the sleeve 63 is compressed into the gas outlet pipe 52, and the gas in the sleeve 63 is compressed into the gas outlet pipe 52. When the gas pressure in the sleeve 63 is greater than the elastic force of the spring 1 69, the high pressure in the sleeve 63 will quickly push the cover 1 64 to move. At this time, the spring 1 610 is compressed, and the hemispherical block 68 is separated from the limit rail 66. The spring 1 69 is compressed. Due to the movement of the cover 1 64, the circular hole 65 can be connected with the sleeve 63, so that the high-pressure gas in the sleeve 63 is quickly discharged into the limit rail 66 through the circular hole 65, and finally sprayed downward through the gas outlet pipe 1 611. Due to the movement of the cover 1 64, the connecting block 2 629 and the circular shaft 1 632 can be driven to move together through the installation rod 628 and the movable arm 631 can be swung. Due to the swing of the movable arm 631, the circular shaft 2 633, the connecting block 1 625, the movable frame 626 and the connecting rod 1 624 can be driven to move in the opposite direction of the connecting block 2 629, and the piston 621, the spring 3 623 and the air cylinder 620 can be driven to move and draw air through the nozzle 619. At this time, a high-speed airflow will be generated inside the nozzle 618. Due to the Burruli principle, the sealing ball 639 can be pushed open by the high pressure. At this time, the spring 4 640 is compressed, and the seal of the connecting pipe 636 by the seat 638 is released, so that the water inside the water tank 32 is sucked into the internal seal of the connecting pipe 636. When the gas pressure inside the sleeve 63 decreases as the circular hole 65 is released, the cover 1 64 can be pushed to move back to the sleeve 63 due to the elastic recovery effect of the spring 2 610, and the connection between the circular hole 65 and the sleeve 63 is released. At the same time, the hemispherical clamping block 68 will be clamped on the slider 67 again under the elastic recovery effect of the spring 1 69, so that the water outlet pipe 52 continues to pressurize the inside of the sleeve 63. Due to the reset movement of the cover 1 64, the movable arm 631 can be driven to resume swinging through the mounting rod 628, the connecting block 2 629 and the circular shaft 1 632. At this time, the connecting block 1 625 will drive the connecting rod 1 624 and the moving block 622 to move. At the same time, the spring 3 623 is compressed. Due to the elastic recovery effect of the spring 3 623,The piston 621 can be pushed to move and reset. At this time, the gas inside the cylinder 620 can be quickly discharged through the nozzle 618 and the nozzle 619, and the Bernoulli principle will be used to press out the water inside the connecting pipe 636, and the water mist will be dispersed by the high airflow and sprayed from the nozzle 619. After the piston 621 is reset, the nozzle 619 will stop spraying. At this time, the air pressure inside the sleeve 63 will rise again to a level greater than the elastic force of the spring 1 69, so that the sleeve 63 is pushed again, and the air outlet pipe 2 611 releases high-pressure gas again, and pressurizes the water mist diffused in the air, accelerating the water mist to sink to the polishing part of the aluminum alloy material, so that the principle of heat absorption by evaporation of water mist can be used to improve the cooling intensity, and at the same time, it will not cause the dilution and loss of the polishing agent. At the same time, the reciprocating alternating operation of the air outlet pipe 2 611 and the nozzle 619 is used to form a way of spraying water mist and then discharging air to further improve the cooling height.

[0070] Due to the movement of the movable frame 626, the fixed rod 627, the movable plate 414 and the round rod 413 can be driven to move together. As the round rod 413 moves, the scraps on the air filter plate 47 are scraped to the inside of the collection box 48 through the scraper block 412, so that the scraps on the air filter plate 47 can be cleaned to avoid the long-term accumulation of scraps on the air filter plate 47 affecting the suction force of the air cooler 41. Since the movable frame 626 will only move when encountering rough welds, and there are one or two welds on each side of the aluminum alloy door frame, the scraper block 412 can clean the air filter plate 47 once or twice when polishing each side, thereby further ensuring the filtration efficiency of the air filter plate 47 and preventing the air filter plate 47 from being blocked.
