Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of extrusion molding devices, and in particular, to an extrusion molding device for processing aluminum alloy profiles. Background Art

[0002] The extrusion forming device for aluminum alloy profile processing is a kind of equipment widely used in the field of aluminum alloy processing. Its main function is to form aluminum alloy materials into profiles of various specifications through the extrusion process.

[0003] In actual production, the aluminum alloy billet is subjected to high pressure in the die through an extruder, so that it is extruded through the die hole and formed into the desired cross-sectional shape. During this process, the aluminum alloy billet is subjected to strong shear force and deformation force, and its grain structure is refined and improved. This type of device usually includes key components such as a workbench, a forming mechanism, a die base, an ejection mechanism, and a discharge mechanism.

[0004] When extruding aluminum alloy profiles, it is necessary to maintain a relatively stable temperature state of the blank during the extrusion process. Generally, a heating furnace is used to heat the blank to a corresponding temperature range before extrusion, and then the blank is extruded. The aluminum alloy profile after extrusion needs to be cooled. In the prior art, water cooling or air cooling is generally used to cool aluminum alloy profiles with simple cross-sectional shapes. However, if the cross-sectional shape of the aluminum alloy is more complex, when water cooling or air cooling is used, due to the limited uniformity of the two and the fast cooling speed, it is easy to cause uneven temperature distribution inside the profile, causing internal stress concentration, thereby causing deformation such as bending and twisting of the profile, and cracks appearing inside or on the surface, affecting its dimensional accuracy and its mechanical properties.

[0027] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] like Figures 1 to 11As shown, it shows an extrusion molding device for aluminum alloy profile processing in an embodiment of the present disclosure, including a main frame 1, the main frame 1 includes a power zone and an extrusion zone, the main frame 1 is installed on a foundation 2, the extrusion zone is installed with an extrusion assembly for extruding the aluminum alloy billet, and also includes a mounting cylinder 3, an extrusion die 4, a uniform cold transition assembly, an air supply assembly and a reheat guide assembly, the mounting cylinder 3 is fixedly installed at the discharge end of the extrusion zone, the extrusion die 4 is detachably installed inside the mounting cylinder 3, the uniform cold transition assembly is installed at the discharge end of the extrusion zone, and is used to cool the extruded aluminum alloy profile in a manner lower than the temperature of the profile itself and gradually cooling it to room temperature, the uniform cold transition assembly includes a bearing frame 5, a bearing cylinder 6, an end mounting The support frame 5 is arranged at the discharge end of the extrusion die 4, the support frame 5 is fixedly mounted on the main frame 1, the support tube 6 is fixedly mounted on the support frame 5, the support tube 6 is coaxially arranged with the mounting tube 3, and two end mounting frames 7 are coaxially fixedly mounted at both ends inside the support tube 6, a plurality of guide rings 8 are coaxially arranged equidistantly between the two end mounting frames 7, a gap exists between each guide ring 8, a groove 9 is arranged at one end of each guide ring 8 away from the mounting tube 3, a plurality of connecting pieces 10 are fixedly mounted at equal angles in a circle between the two end mounting frames 7, each connecting piece 10 is fixedly connected to a plurality of guide rings 8, and the heating part is mounted on the support tube 6 for providing heat.

[0029] Specifically, when the aluminum alloy billet is extruded, the billet needs to be heated first. When it is heated to the required temperature range, the heated billet can be removed, cut into a length convenient for extrusion, and placed on the corresponding feeding equipment. The feeding equipment of the extrusion molding device is generally arranged at the bottom of the main frame 1. When loading, the position of the extrusion assembly is adjusted, and the billet is sent to the reheating guide assembly. In this process, affected by the environment and the initial heating temperature, the billet at this time may not achieve a good extrusion effect. At this time, the reheating guide assembly is started to heat the billet again to make it reach the optimal extrusion temperature, so as to facilitate extrusion molding. Then, the end of the reheating guide assembly is abutted against the entrance end of the mounting cylinder 3, and the extrusion assembly is started and moved to the working position. The billet can be extruded through the setting of the extrusion assembly. Under the action of the extrusion die 4, the aluminum alloy is extruded. After the aluminum alloy profile is extruded, it will enter the inside of the supporting tube 6, that is, enter the end mounting frame 7. At this time, the formed aluminum alloy profile needs to be cooled. In order to avoid stress concentration and deformation caused by too fast cooling, the heating part is started at this time to transfer the heat to the connecting piece 10, and then the air supply component is started to evenly supply air to the inside of the supporting tube 6. At this time, the guide ring 8 entering the end mounting frame 7 guides the wind flow direction, so that the wind passes through the gap between the guide rings 8 after being heated by the connecting piece 10, forming uniform and gentle hot air. The hot air temperature is lower than the temperature of the profile when it is extruded, and the profile is cooled. Through the guiding effect of the groove 9, the wind will flow in the moving direction of the profile, thereby gradually reducing the temperature of the profile, ensuring a smooth cooling process, avoiding internal stress caused by sudden temperature changes, and finally achieving a high-quality cooling effect with a smooth profile surface and a stable internal structure, ensuring that the product performance meets the standards.

[0030] It should be added that, before extrusion, in order to maintain a good extrusion effect, the extrusion die 4 needs to be heated to achieve a better molding effect.

[0031] The above, such as Figures 5 to 7 As shown, the heating part includes a first heater 11, which is fixedly mounted on the supporting tube 6, and also includes a first heating wire 12, which is fixedly mounted between two end mounting frames 7, the first heating wire 12 is fixedly connected to the output end of the first heater 11, and the first heating wire 12 is fixedly connected to a plurality of connecting plates 10.

[0032] Specifically, when the formed aluminum alloy profile is cooled, in order to increase the temperature, the first heater 11 is started. The first heater 11 heats the connecting piece 10 through the setting of the first heating wire 12 to increase its temperature. During the cooling process, when the wind passes through the connecting piece 10, the wind can be preheated to ensure that the hot air temperature is moderate, thereby avoiding the profile from generating internal stress due to excessive temperature difference, thereby ensuring cooling uniformity and improving profile quality.

[0033] like Figure 8 As shown, the air supply assembly is installed on the uniform cooling transition assembly, and the air supply direction is tangently arranged to provide wind force. The air supply assembly includes an exhaust tube 13, an inclined hole 14, an annular groove 15 and a uniform exhaust portion. The exhaust tube 13 is coaxially rotatably installed on the two end mounting frames 7. The exhaust tube 13 is rotatably connected to the supporting tube 6. A plurality of groups of inclined holes 14 are equidistantly provided in the exhaust tube 13. Each group of inclined holes 14 is arranged in a circle with equal angles around the axial position of the exhaust tube 13 as the center. Each inclined hole 14 has the same inclination direction. An annular groove 15 is coaxially provided on the exhaust tube 13. The uniform exhaust portion is installed inside the supporting tube 6 to uniformly supply air through the inclined holes 14.

[0034] Specifically, when conveying wind, air is blown into the exhaust tube 13 through the setting of the uniform exhaust part, and the air passes through the annular groove 15 and flows out in a vortex shape through the inclined hole 14, forming a stable wind field, ensuring uniform coverage of the profile surface, and during the rotation of the exhaust tube 13, the annular groove 15 and the exhaust tube 13 produce relative rotation, which does not affect the air delivery.

[0035] The above, such as Figure 8 As shown, the uniform exhaust part includes a tangential exhaust frame 16 and a blower 17. The tangential exhaust frame 16 is coaxially fixedly installed inside the bearing tube 6. The tangential exhaust frame 16 is rotatably and sealingly connected to the annular groove 15. The air inlet end of the tangential exhaust frame 16 is tangentially arranged on the side of the tangential exhaust frame 16. The blower 17 is fixedly installed on the bearing frame 5. The output end of the blower 17 is connected to the air inlet end of the tangential exhaust frame 16. It also includes a gear ring 18, a motor 19 and a driving gear 20. The gear ring 18 is coaxially fixedly installed on the exhaust tube 13, the motor 19 is fixedly installed on the bearing frame 5, and the output end of the motor 19 is coaxially fixedly installed with a driving gear 20, which meshes with the gear ring 18.

[0036] Specifically, when wind power is provided, the blower 17 is started and air is introduced into the tangential exhaust frame 16, so that the air passes through the annular groove 15 and enters the exhaust tube 13, forming a vortex wind field, ensuring that the surface of the profile is evenly exposed to the wind, and the synchronous motor 19 drives the gear ring 18 to rotate the exhaust tube 13, thereby optimizing the wind field distribution, further improving the exhaust effect, and ensuring the quality of the profile.

[0037] like Fig. 9 , Fig.10As shown, the reheat guide assembly is installed in the extrusion zone, and is used for reheating the aluminum alloy billet to be extruded and sending it to the inside of the mounting cylinder 3. The reheat guide assembly includes a guide frame 21, a guide cylinder 22, a feeding hole 23, a push rod 24, a first hydraulic cylinder 25 and a pre-forming reheating section. The guide frame 21 is slidably installed in the extrusion zone, and the guide cylinder 22 is fixedly installed on the guide frame 21. The guide cylinder 22 is provided with a feeding hole 23, and the feeding hole 23 is coaxially arranged with the mounting cylinder 3. Four push rods 24 are symmetrically and fixedly installed on the guide frame 21, and four first hydraulic cylinders 25 are symmetrically and fixedly installed in the power zone. The output ends of the first hydraulic cylinders 25 are respectively fixedly connected to the four push rods 24, and the pre-forming reheating section is installed in the guide cylinder 22 for reheating the billet.

[0038] It should be added that when extruding aluminum alloy profiles, uneven heating of the billet will lead to inconsistent fluidity of the material during the extrusion process, thereby causing surface defects or dimensional deviations in the finished aluminum alloy profiles. Specifically, when the temperature is too high, the aluminum alloy will be overburned, the grains will be coarse, and the mechanical properties of the profile will be reduced. When the temperature is too low, it will cause extrusion difficulties, the profile surface will be rough or cracks will appear. Therefore, it is necessary to keep the billet at a relatively stable temperature during the extrusion process. Generally, a heating furnace is used to heat the billet to the corresponding temperature range before extrusion, and then the billet is extruded. However, after the billet is heated in a heating furnace and before it is extruded, since the billet is exposed to the air during the extrusion process, it will dissipate heat to the surrounding environment through radiation and convection, resulting in a drop in temperature, which in turn affects the dimensional accuracy of the profile.

[0039] Specifically, the blank needs to be heated again before extrusion to ensure that its temperature is stable during the extrusion process and reduce the influence of heat dissipation, thereby improving the surface quality and dimensional accuracy of the profile. After the blank is fed into the feeding hole 23, the pre-molding reheating section is started to heat it to the target temperature to ensure that the blank is heated evenly and effectively avoid temperature fluctuations. At this time, the first hydraulic cylinder 25 is started, and the guide frame 21 is moved to the predetermined position of the extrusion area through the push rod 24, and extrusion can begin.

[0040] The above, such as Fig.10 As shown, the pre-molding reheating section includes a second heater 26, which is fixedly mounted on the guide frame 21, and also includes a second heating wire 27, which is fixedly mounted inside the guide cylinder 22, and the second heating wire 27 is fixedly connected to the output end of the second heater 26.

[0041] Specifically, when the blank before molding is heated again, the second heater 26 is started. The second heater 26 heats the blank evenly through the setting of the second heating wire 27 to ensure that its temperature reaches a preset value, thereby effectively reducing profile defects caused by temperature fluctuations and improving product quality.

[0042] The above, such as Fig.11 As shown, the extrusion assembly includes a working frame 28, a second hydraulic cylinder 29 and an extrusion part. The working frame 28 is slidably installed inside the extrusion area. The working frame 28 and the push rod 24 are slidably matched. Two second hydraulic cylinders 29 are symmetrically and fixedly installed inside the power area. The output ends of the two second hydraulic cylinders 29 are fixedly connected to the working frame 28. The extrusion part is installed on the working frame 28 for extruding the billet.

[0043] Specifically, when the blank is extruded, the second hydraulic cylinder 29 is started, and the second hydraulic cylinder 29 pushes the working frame 28 to move, thereby driving the extrusion part to move. Through the setting of the extrusion part, uniform pressure is applied to the blank to ensure that it is extruded at a stable temperature.

[0044] The above, such as Fig.11 As shown, the extrusion part includes a sliding frame 30, an electric cylinder 31 and an extrusion rod 32. The sliding frame 30 is slidably installed on the working frame 28, the electric cylinder 31 is fixedly installed inside the sliding frame 30, and the output end of the electric cylinder 31 is fixedly connected to the sliding frame 30. The extrusion rod 32 is fixedly installed on the sliding frame 30, and the extrusion rod 32 is coaxially arranged with the material placement hole 23.

[0045] Specifically, during the extrusion process, the extrusion rod 32 is used to support the blank in the feeding hole 23, and the aluminum alloy profile is extruded as the working frame 28 moves. During the loading process, the electric cylinder 31 is started, and the electric cylinder 31 pushes the sliding frame 30 to move, so that the extrusion rod 32 moves away from the feeding hole 23 to facilitate the smooth entry of the blank. The electric cylinder 31 can be retracted when extrusion is needed.

[0046] The working principle or usage process of this application is: When extruding an aluminum alloy billet, it is necessary to heat the billet first. When heated to the required temperature range, the heated billet can be removed, cut into a length convenient for extrusion, and placed on a corresponding loading device. The loading device of the extrusion molding device is generally arranged at the bottom of the main frame 1. When loading, the electric cylinder 31 is started, and the electric cylinder 31 pushes the sliding frame 30 to move, so that the extrusion rod 32 moves away from the placing hole 23, so that the billet can smoothly enter the placing hole 23. After the loading is completed, the loading assembly and the electric cylinder 31 can be retracted.

[0047] In this process, affected by the environment and the initial heating temperature, the billet at this time may not achieve a good extrusion effect. In order to ensure the stability of the billet temperature during the extrusion process, the billet needs to be heated again before extrusion to ensure that its temperature is stable during the extrusion process and reduce the heat dissipation effect, thereby improving the profile surface quality and dimensional accuracy. After the billet is fed into the feeding hole 23, the second heater 26 is started at this time. The second heater 26 is set by the second heating wire 27 to uniformly heat the billet to ensure that its temperature reaches the preset value, thereby effectively reducing profile defects caused by temperature fluctuations and improving product quality.

[0048] At this time, the first hydraulic cylinder 25 can be started, and the guide frame 21 can be moved to the predetermined position of the extrusion area through the push rod 24 to start extrusion. The second hydraulic cylinder 29 is started, and the second hydraulic cylinder 29 pushes the working frame 28 to move, thereby driving the extrusion rod 32 to move. Through the setting of the extrusion rod 32, uniform pressure is applied to the blank, and under the action of the extrusion die 4, the aluminum alloy profile is extruded.

[0049] After the aluminum alloy profile is extruded, it will enter the interior of the bearing tube 6, that is, enter the end mounting frame 7. At this time, the formed aluminum alloy profile needs to be cooled. In order to avoid stress concentration and deformation caused by excessive cooling, the first heater 11 is started at this time. The first heater 11 heats the connecting piece 10 through the setting of the first heating wire 12 to increase its temperature. At this time, the blower 17 is started, and the air is introduced into the tangential exhaust frame 16, so that the air passes through the annular groove 15 and enters the exhaust cylinder 13, forming a vortex wind field, ensuring that the surface of the profile is evenly affected by the wind. The synchronous motor 19 drives the gear ring 18 to rotate the exhaust cylinder 13, optimize the wind field distribution, and further improve the exhaust effect. The air passes through the annular groove 15 and flows out through the inclined hole 14 in a vortex shape, forming a stable wind field, ensuring that the surface of the profile is evenly covered. During the rotation of the exhaust cylinder 13, the annular groove 15 and the exhaust cylinder 13 rotate relative to each other without affecting the air transportation. During the cooling process, when the wind passes through the connecting piece 10, the wind can be preheated to ensure that the hot air temperature is moderate. The temperature at this time must be lower than the temperature when the profile is extruded to avoid internal stress in the profile due to excessive temperature difference, thereby ensuring cooling uniformity and improving profile quality.

[0050] Through the guiding effect of the groove 9, the wind will flow in the moving direction of the profile, thereby gradually reducing the profile temperature, ensuring a smooth cooling process, avoiding internal stress caused by sudden temperature changes, and ultimately achieving a high-quality cooling effect with a smooth profile surface and a stable internal structure, ensuring that product performance meets the standards.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
