[0002] Aluminum profile extrusion machines are specialized equipment used to heat aluminum alloy bars at high temperatures and then extrude them into profiles of various shapes through dies. These machines are widely used in construction, transportation, electronics, machinery, and other fields, and are capable of producing aluminum profiles with cross-sectional shapes ranging from simple to complex.

[0003] Currently, the existing processing steps generally involve heating the aluminum alloy bar in a separate device and then transferring the heated aluminum bar to the extrusion equipment.

A bearing seat 63 is fixedly connected to the top of the extrusion box 1, and one end of the rotating shaft 61 is rotatably connected to the side wall of the bearing seat 63. The extrusion box 1 is provided with a driving part that drives the rotating shaft 61 to rotate intermittently; the driving part includes a gear plate 64, which is fixed on the outer wall of the rotating shaft 61, and a single-tooth gear 65 is rotatably connected to the top of the extrusion box 1, and the single-tooth gear 65 is meshed with the gear plate 64. A first runner 651 is fixedly connected to the side wall of the single-tooth gear 65, and a second runner 66 is fixedly connected to the threaded rod 52 through a one-way bearing. The first runner 651 and the second runner 66 are connected by a belt drive.

[0034] It should be noted that the servo motor 55 is a bidirectional motor for flexibly controlling the forward and reverse rotation of the threaded rod 52; the four sets of partition plates 62 divide the feeding tank 4 into four cavities (such as Figure 7 ), the one connected to the top opening of the feeding tank 4 is the feeding cavity, the one connected to the heater 2 is the heating cavity, the one connected to the extrusion groove 3 is the unloading cavity, and the remaining one is an unloaded cavity; the one-way bearing on the threaded rod 52 can only drive the second rotating wheel 66 to rotate in one reverse direction, so as to ensure that the rotating shaft 61 will only continue to rotate in one direction, and at the same time ensure that the aluminum rod heating cavity obtains sufficient heating time, and every time the threaded rod 52 rotates back and forth for a cycle, the single-tooth gear 65 just drives the gear plate 64 to rotate 90 degrees to realize the switching of different workstations.

[0035] Through the arrangement of the above structure, the cut aluminum rod is placed into the loading cavity from the open top of the loading tank 4, and the heater 2 is turned on to heat the heating cavity. Then the servo motor 55 drives the threaded rod 52 to rotate forward. At this time, the pushing plate 54 will slide along the threaded rod 52 to the side close to the positioning frame 5, and pull the extrusion rod 32 to slide outward along the extrusion groove 3. At the same time, by utilizing the transmission effect between the first rotating wheel 651, the second rotating wheel 66 and the belt, when the threaded rod 52 rotates forward, it will drive the single-tooth gear 65 to rotate in conjunction with the arrangement of the one-way bearing, thereby driving the gear plate 64 to rotate. When the extrusion rod 32 is pulled out to the predetermined position, the gear plate 64 just rotates 90 degrees, thereby also driving the rotating shaft 61, the rotating disk 6 and each group of partition plates 62 to rotate 90 degrees. At this time, the aluminum rod previously in the loading cavity will move to the heating cavity for heating, and the previously unloaded The cavity will select the loading cavity to continue loading. In addition, the aluminum rod in the previous heating cavity will be pushed to the unloading cavity and fall into the extrusion groove 3, thereby effectively avoiding the heat loss of the aluminum rod and improving the extrusion effect; then the servo motor 55 drives the threaded rod 52 to rotate in the opposite direction. Due to the action of the one-way bearing, the second rotor 66 will no longer rotate at this time to ensure that the aluminum rod in the heating cavity obtains sufficient heating time, thereby improving the heating effect; next, the pushing plate 54 pushes the extrusion rod 32 to move into the extrusion groove 3, thereby pushing the high-temperature aluminum rod to move toward the forming die 31. Finally, under the action of a strong extrusion force, the high-temperature aluminum rod will pass through the forming groove in the middle of the forming die 31, thereby completing the extrusion production of the aluminum profile, and then in the process of the extrusion rod 32 exiting the extrusion groove 3, the new heated aluminum rod will enter the extrusion groove 3 again, thereby effectively improving the extrusion efficiency.

[0036] Reference Figure 1-Figure 3 、 Figure 7 and Figure 8 , wherein, each set of partition plates 62 is rotatably connected with two sets of friction rollers 67, both ends of each set of friction rollers 67 pass through the rotating disk 6 and are fixedly connected with a driven gear 671, and three sets of mounting brackets 68 are fixed at equal intervals on the side walls of both ends of the extrusion box 1, and a double-sided gear ring 681 is clamped between the three sets of mounting brackets 68, and the double-sided gear ring 681 is meshed with multiple sets of driven gears 671. A driven runner 682 is fixedly connected to the middle of the double-sided gear ring 681 near the gear disk 64, and the driven runner 682 is connected to the threaded rod 52 through a first pulley group 683; the outer wall of the double-sided gear ring 681 fits and rotates with the inner wall of the mounting bracket 68, and the central axis of the double-sided gear ring 681 coincides with the central axis of the rotating shaft 61.

[0037] Through the arrangement of the above structure, during the reverse rotation of the threaded rod 52, the transmission action of the first pulley group 683 will drive the driven rotating wheel 682 and the double-sided gear ring 681 to rotate. At this time, the meshing relationship between the double-sided gear ring 681 and the driven gear 671 will cause the friction roller 67 to rotate, thereby utilizing the friction action to push the aluminum rod to rotate in the heating chamber, ensuring that the aluminum rod can be heated evenly, thereby effectively improving the heating efficiency.

[0038] Reference Figure 3-Figure 6 , wherein the cooling assembly includes a discharge pipe 7, the discharge pipe 7 is fixed on the outer wall of the end of the extrusion box 1, and the central axis of the discharge pipe 7 coincides with the central axis of the forming die 31, the discharge pipe 7 is fixed and connected to a cooling plate 71, the inner wall of the cooling plate 71 is fixedly connected to positioning rings 72 on both sides, and a water cooling plate 73 is rotatably connected between the positioning rings 72 on both sides, and a water groove 721 is opened in one side of the positioning ring 72, and the water groove 721 is connected to the inner cavity of the water cooling plate 73, and the water cooling plate 73 is evenly spaced from the side near the center of the discharge pipe 7. There are multiple groups of atomizing spray holes 731, and a water supply part for conveying water to the water cooling plate 73 is provided in the extrusion box 1; the water supply part includes a water supply trough 74, which is provided in the extrusion box 1, and an extrusion plate 741 is slidably connected in the water supply trough 74, and an extrusion rod 742 is fixedly connected between the side wall of the extrusion plate 741 and the bottom of the push plate 54, and the bottom of the water trough 721 is fixed and connected to a water inlet pipe 75, the other end of the water inlet pipe 75 is connected to the inner cavity of the water supply trough 74, and a one-way valve is provided in the water inlet pipe 75.

[0039] It should be noted that the one-way valve in the water inlet pipe 75 can only allow the water in the water supply tank 74 to flow into the water cooling plate 73 .

[0040] Through the arrangement of the above structure, while the pushing plate 54 pushes the extrusion rod 32 to perform extrusion molding, it also drives the extrusion rod 742 to move into the water supply tank 74, thereby squeezing the cooling water flow in the water supply tank 74, thereby opening the one-way valve in the water inlet pipe 75, allowing the water to flow along the water inlet pipe 75 and the water trough 721 into the water cooling plate 73, and then sprayed onto the extruded aluminum profile by multiple groups of atomizing nozzles 731, so that the aluminum profile is quickly cooled and dissipated, thereby effectively improving the cooling efficiency.

[0041] Reference Figure 3 、 Figure 5 and Figure 6 Among them, multiple groups of return water grooves 722 are opened at equal intervals on the upper part of the positioning ring 72 on the other side, and a water collecting groove 76 is opened in the extrusion box 1. The water collecting groove 76 is connected to the bottom of the inner cavity of the cooling plate 71 through a return water pipe 761, and the water collecting groove 76 is connected to the water supply groove 74 through a water replenishment groove 762, and a one-way valve is provided in the water replenishment groove 762.

[0042] It should be noted that the one-way valve in the water replenishment tank 762 can only allow the water in the water collection tank 76 to flow into the water supply tank 74.

[0043] Through the setting of the above structure, the water flow sprayed and dripping to the bottom of the cooling plate 71 will enter the water collecting tank 76 along the return water tank 722 and the return water pipe 761. When the extrusion rod 742 moves in the opposite direction following the push plate 54, a suction effect will be generated in the water supply tank 74, thereby opening the one-way valve in the water replenishment tank 762, so that the water flow in the water collecting tank 76 is sucked into the water supply tank 74 for replenishment, thereby realizing the recycling of water flow, reducing water resource loss, and improving energy saving effect.

[0044] Reference Figure 3 、 Figure 4 , wherein, a driving chamber 77 is fixedly connected to the top of the cooling disk 71, the driving chamber 77 is communicated with the inner cavity of the cooling disk 71, and a friction wheel 771 is rotatably connected in the driving chamber 77, and the friction wheel 771 rotates in contact with the outer wall of the water-cooling disk 73, and a linkage shaft 78 is fixedly connected to the middle of the double-sided gear ring 681 near the side of the driving chamber 77, and the rotating shaft of the friction wheel 771 and the linkage shaft 78 are connected for transmission via a second pulley set 781.

[0045] Through the arrangement of the above structure, when the friction roller 67 rotates, the meshing relationship between the driven gear 671 on the other side and the double-sided gear ring 681 will cause the double-sided gear ring 681 on the other side to rotate. At this time, the transmission action of the second pulley set 781 will cause the friction wheel 771 to rotate, thereby driving the water cooling plate 73 to rotate under the action of friction force, causing the sprayed water flow to rotate, thereby achieving uniform water cooling of the aluminum profile, improving the water cooling efficiency, and completing the uniform water cooling effect, avoiding the local cooling temperature difference of the aluminum profile, and effectively ensuring the output quality of the aluminum profile.

[0046] Reference Figures 1-8In the present invention, when in use, the cut aluminum rod is placed into the loading cavity from the open top of the loading tank 4, and the heater 2 is turned on to heat the heating cavity. Then the servo motor 55 drives the threaded rod 52 to rotate forward. At this time, the pushing plate 54 will slide along the threaded rod 52 to the side close to the positioning frame 5, and pull the extrusion rod 32 to slide outward along the extrusion groove 3. At the same time, by utilizing the transmission effect between the first rotating wheel 651, the second rotating wheel 66 and the belt, when the threaded rod 52 rotates forward, the one-way bearing will drive the single-tooth gear 65 to rotate, thereby driving the gear plate 64 to rotate, and when the extrusion rod 32 is pulled out to the predetermined position, the gear plate 64 just rotates 90 degrees, thereby also driving the rotating shaft 61, the rotating disk 6 and each set of partition plates 62 to rotate 90 degrees. At this time, the aluminum rod previously in the loading cavity will move to the heating cavity. The aluminum rod in the heating cavity is heated, and the previously unloaded cavity will be selected to continue loading into the loading cavity. In addition, the aluminum rod in the previously heated cavity will be pushed to the unloading cavity and fall into the extrusion groove 3; then the servo motor 55 drives the threaded rod 52 to rotate in the opposite direction. Due to the action of the one-way bearing, the second runner 66 will no longer rotate at this time to ensure that the aluminum rod in the heating cavity obtains sufficient heating time, thereby improving the heating effect; next, the push plate 54 pushes the extrusion rod 32 to move into the extrusion groove 3, thereby pushing the high-temperature aluminum rod to move toward the forming die 31, and finally, under the action of a strong extrusion force, the high-temperature aluminum rod will pass through the forming groove in the middle of the forming die 31, thereby completing the extrusion production of the aluminum profile, and then in the process of the extrusion rod 32 exiting the extrusion groove 3, the new heated aluminum rod will enter the extrusion groove 3 again, thereby effectively improving the extrusion efficiency.

[0047] When the pushing plate 54 pushes the extrusion rod 32 to extrude the material, it will also drive the extrusion rod 742 to move into the water supply trough 74, thereby squeezing the cooling water flow in the water supply trough 74, so as to open the one-way valve in the water inlet pipe 75, so that the water flows along the water inlet pipe 75 and the water trough 721 into the water cooling plate 73, and then is sprayed onto the extruded aluminum profile by the multiple groups of atomizing nozzles 731, so that the aluminum profile is quickly cooled and dissipated, thereby effectively improving the cooling efficiency; and the water flow sprayed and dripping to the bottom of the cooling plate 71 will enter the water collection trough 76 along the return water trough 722 and the return water pipe 761, and when the extrusion rod 742 moves in the opposite direction following the pushing plate 54, a suction effect will be generated in the water supply trough 74, thereby opening the one-way valve in the water replenishment trough 762, so that the water flow in the water collection trough 76 is sucked into the water supply trough 74 for replenishment, thereby realizing the recycling of water flow, reducing water resource loss and improving energy saving effect.

[0048] In the process of reverse rotation of the threaded rod 52, the transmission effect of the first pulley group 683 will drive the driven runner 682 and the double-sided gear ring 681 to rotate. At this time, the meshing relationship between the double-sided gear ring 681 and the driven gear 671 will cause the friction roller 67 to rotate, thereby using the friction effect to push the aluminum rod to rotate in the heating chamber, ensuring that the aluminum rod can be evenly heated, effectively improving the heating efficiency; and when the friction roller 67 rotates, the meshing relationship between the driven runner 682 on the other side and the double-sided gear ring 681 will cause the double-sided gear ring 681 on the other side to rotate. At this time, the transmission effect of the second pulley group 781 will cause the friction wheel 771 to rotate, thereby driving the water cooling plate 73 to rotate under the action of friction, causing the sprayed water flow to rotate, thereby achieving uniform water cooling of the aluminum profile, improving the water cooling efficiency, and also completing the uniform water cooling effect, effectively ensuring the output quality of the aluminum profile.
