Description

Technical Field

[0001] The present invention relates to the technical field of extrusion forming manufacturing, and more particularly to a high-elongation aluminum material extrusion manufacturing device and process. Background Art

[0002] Aluminum extrusion is a process that extrudes aluminum alloy through a die to create the desired cross-sectional shape. This technique exploits the metal's plasticity, causing it to deform under high temperature and pressure to produce products with specific cross-sectional shapes and dimensions. The main process involves heating an aluminum bar to a suitable extrusion temperature, typically between 450°C and 500°C. A powerful hydraulic system then pushes the heated bar through a die to achieve the desired cross-sectional shape.

[0003] Since the temperature of the extruded aluminum is relatively high, in order to prevent the grain growth of the material, control the microstructure of the material, and make the material achieve the ideal hardness and strength, the extruded material needs to be cooled in time. Among them, for some high-quality aluminum alloy profiles, their ductility is higher, so they are easier to form, and therefore they are widely used. However, in the actual processing process, since such materials are in a high temperature state during extrusion and their own ductility is high, the material is relatively soft. Therefore, in order to avoid secondary stretching of the material during the traction process of the traction equipment (there is an error between the traction speed of the traction equipment and the material extrusion speed of the extrusion equipment) and bending of the material itself (the material bends due to its own gravity when passing through the suspended area), the material must be cooled efficiently and quickly when it is extruded from the extrusion equipment, such as water cooling (spraying cold water on the material or passing the material through a water tank) to ensure that the extruded material can harden quickly to avoid accidents.

[0004] During the extrusion process of aluminum profiles, for materials with regular and uniform cross-sectional shapes, such as quadrilateral tubes and profiles with the same protruding structure on all four sides, when such structures are actually cooled, due to the uniform material structure, the cooling rate and cooling effect of different areas of the material are not much different during cooling, so the temperature difference deformation caused is almost negligible. However, for some aluminum profile structures, in addition to the tubular main structure, flat-plate wing structures extending outward are set on two or more sides of the tube (serving as a base plate or installation support during the use of the profile).

[0005] For this type of aluminum profile, its outer wing is in a suspended state, that is, there is no obstruction. During the rapid cooling process, both sides of the wing can contact the cooling medium (water) at the same time, and the cooling speed is relatively fast. However, the air inside the tubular main structure is in a high temperature state. Therefore, the tubular main structure is affected by the internal high-temperature air, and the cooling speed is relatively slow, resulting in a temperature change difference, which leads to a cooling shrinkage deformation difference between the wing and the tubular main structure, and then makes the wing easy to produce irregular deformation (for example, the edge of the wing produces wavy deformation), affecting the actual forming quality and forming accuracy of the material. Summary of the Invention

[0006] The present invention provides a high-elongation aluminum extrusion manufacturing device and process, which aims to solve the problem that: when the existing aluminum profile with suspended side wing plates is cooled after being extruded during the extrusion molding process, the cooling rate on both sides of the wing plate is relatively fast, resulting in a cooling shrinkage deformation difference between the wing plate and the tubular main structure, which in turn makes the wing plate prone to irregular deformation, affecting the actual forming quality and forming accuracy of the material.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-elongation aluminum extrusion manufacturing device, comprising an aluminum profile extruder, an aluminum profile conveying assembly, a mobile tractor and a cooling assembly, wherein the cooling assembly is arranged at the output end of the aluminum profile extruder;

[0008] The cooling assembly includes two sets of cooling racks, a water cooling assembly is arranged between the two sets of cooling racks, and a covering assembly is arranged at the position of the cooling rack corresponding to the wing plate structure;

[0009] The covering assembly includes multiple groups of covering plates arranged in a circular manner, and each group of covering plates is provided with two upper and lower plates. A circular movement control assembly and a heating assembly are also installed inside the cooling rack. The circular movement control assembly is used to drive the upper and lower covering plates of each group to approach and move away from the wing plate structure, and to drive the covering plates to move synchronously with the aluminum profile when the covering plates are fitted with the wing plate structure. The heating assembly is used to heat the covering plates.

[0010] In a preferred embodiment, the two cladding plates in each group are respectively arranged corresponding to the upper and lower surfaces of the wing plate structure. The cladding plates are plate-shaped metal structures adapted to the shape of the wing plate structure, and the hardness of the cladding plates is higher than that of the wing plate structure at the same temperature.

[0011] In a preferred embodiment, the cyclic movement control component is a crawler-type cyclic movement control component, which includes track shoes, track wheels and an installation box. The installation box is fixedly installed in the cooling rack, and the track shoes and track wheels are arranged in the installation box. The track shoes are provided in multiple numbers, and the multiple track shoes are hinged in sequence to form a track structure. The track wheels are used to support the track structure formed by the track shoes. The track wheels have rotational power, and each group of covering plates is respectively installed on the corresponding track shoes.

[0012] In a preferred embodiment, a guide structure is provided on the track plate, and the covering plate is slidably arranged on the track plate through the guide structure. The covering assembly further includes a moving drive assembly for driving the two groups of covering plates to move closer to or away from each other.

[0013] In a preferred embodiment, the mobile drive assembly includes two groups of guide frames, which are fixedly mounted on the cooling frame, and the two groups of guide frames are respectively arranged corresponding to the upper and lower areas of each group of covering plates. A restriction area is formed between the two groups of guide frames, and a reset elastic member is installed between the upper and lower covering plates of each group. A pressure-touch portion is provided on the covering plate corresponding to the restriction area of the guide frame, and the two ends of the restriction area of the guide frame are arranged to be open.

[0014] In a preferred embodiment, multiple sets of guide pressure wheels are rotatably mounted on the guide frame, and the guide pressure wheels roll with the pressure contact portion. A rubber layer is provided on the outside of the guide pressure wheels, and when the guide pressure wheels contact the pressure contact portion, the rubber layer is extruded and deformed.

[0015] In a preferred embodiment, a cleaning component is provided in the installation box, and the cleaning component includes a cleaning air pipe. The cleaning air pipe is fixedly installed in the installation box, and the cleaning air pipe is located in the heating area of the heating component. The cleaning air pipe is connected to the high-pressure air pump through a pipeline, and the output end of the cleaning air pipe corresponds to the area between the upper and lower covering plates.

[0016] In a preferred embodiment, the output end of the clean air pipe is arranged close to the track shoe, and a back-blowing end cap is rotatably installed on the output end of the clean air pipe. The back-blowing end cap is a conical structure, and the opening of the back-blowing end cap is located in the outer wall area of the clean air pipe. An output channel away from the track shoe is formed between the opening of the back-blowing end cap and the outer wall of the clean air pipe, and multiple groups of blade plates are fixedly connected to the inner wall of the back-blowing end cap opening.

[0017] In a preferred embodiment, the water cooling component is a spray-type water cooling device, which includes multiple groups of spray heads. The spray heads are installed on a cooling rack. A water tank is provided at the bottom of the cooling processing space between two groups of cooling racks. A recovery water pipe is installed on the water tank. The multiple groups of spray heads form a water spray structure arranged around the aluminum profile.

[0018] A high-elongation aluminum extrusion manufacturing process comprises the following steps:

[0019] Step 1: Place the preheated aluminum rod into the inner cavity of the aluminum profile extruder, and apply pressure to the aluminum rod in the inner cavity through the extrusion equipment to extrude the aluminum from the corresponding die to form a continuous aluminum profile;

[0020] Step 2: Pass the initially extruded aluminum profile through the area between the two cooling racks, pass the wing plate structure through the corresponding cladding plate, and then pass through the water cooling area of the water cooling assembly;

[0021] Step 3: Clamp the end of the aluminum profile by the clamping mechanism in the mobile traction machine, and drive the mobile traction machine to move and traction it, and cooperate with the extrusion equipment on the aluminum profile extruder to continue to apply pressure and continue extrusion;

[0022] Step 4: Heat the cladding plate by a heating assembly so that the temperature of the cladding plate is the same as the temperature of the aluminum profile when it is extruded;

[0023] Step 5: The upper and lower cladding plates of the corresponding group are driven by the cyclic movement control component to approach the wing plate structure, and then adhere to the wing plate structure to form a cover and then follow the movement of the aluminum profile to enter the water cooling area of the water cooling component for cooling;

[0024] Step 6: After cooling is completed, the circular movement control component controls the upper and lower cladding plates of the corresponding group to move away from the wing plate structure and return to the initial position to wait for use.

[0025] The beneficial effect of the present invention is that the present invention is covered by a covering plate and a wing plate structure, and then passes through the water cooling area of the water cooling component together with the aluminum profile. At this time, the tubular body is directly in contact with water for cooling, but because the air temperature inside the tubular body is high, the cooling rate of the tubular body is lower than the cooling rate when both sides are in contact with water at the same time. Since the outside of the wing plate structure is covered with the covering plate, it is equivalent to increasing the thickness. Therefore, when in contact with water, the cooling rate of the wing plate structure can be slightly slowed down, thereby relatively reducing the water cooling rate difference between the wing plate structure and the tubular body, thereby reducing the uneven deformation of the wing plate structure. Even if the wing plate structure is likely to be deformed due to the material itself or processing errors, since the covering plate covers both sides of the wing plate structure throughout the water cooling operation, the wing plate structure is clamped and positioned, further avoiding irregular deformation of the wing plate structure, thereby greatly improving the product qualification rate of aluminum profiles with wing plate structures, reducing the scrap rate, thereby improving product quality, reducing material waste, and greatly improving the processing accuracy and practicality of the manufacturing device.

[0040] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0041] Refer to the instruction manual Figures 1 to 12 A high-elongation aluminum extrusion manufacturing device includes an aluminum profile extruder 1, an aluminum profile conveying assembly 2, a mobile traction machine 3 and a cooling assembly 4. The aluminum profile extruder 1 is used to apply pressure to the aluminum rod put into its inner cavity to extrude the aluminum from the corresponding die, thereby forming a continuous aluminum profile 5. The mobile traction machine 3 is provided with a clamping mechanism to clamp the end of the aluminum profile 5 and pull the aluminum profile 5 to move, cooperating with the continuous extrusion discharge inside the aluminum profile extruder 1 to form a traction on the aluminum profile 5 and transport the aluminum profile 5 on the aluminum profile conveying assembly 2. The cooling assembly Part 4 is arranged at the output end of the aluminum profile extruder 1 (that is, the position where the aluminum profile 5 is extruded), and the cooling component 4 includes two groups of cooling racks 41. There is a (cooling processing space) between the two groups of cooling racks 41. After the aluminum profile 5 is extruded, it passes through the area between the two groups of cooling racks 41 and is then led to the aluminum profile conveying component 2. A water cooling component 42 is arranged between the two groups of cooling racks 41, and the area covered by the water cooling component 42 is the water cooling area. When the aluminum profile 5 passes through the area between the two groups of cooling racks 41, it passes through the water cooling area of the water cooling component 42 for rapid cooling and shaping.

[0042] It should be noted that the above-mentioned aluminum profile extruder 1, aluminum profile conveying assembly 2 and mobile traction machine 3 are all commonly used equipment in the aluminum profile production process. Their specific structures will not be explained in detail in this embodiment. Other related equipment such as aluminum profile cutting and alternating replacement of mobile traction machine 3 are also existing technologies and will not be elaborated in this embodiment.

[0043] In fact, the aluminum profile 5 is composed of a tubular main body 51 and a wing plate structure 52. In this embodiment, two groups of wing plate structures 52 are provided, and the two groups of wing plate structures 52 are symmetrically arranged on both sides of the tubular main body 51. A covering component 6 is provided at the position corresponding to the wing plate structure 52 in the cooling rack 41. Based on the fact that two groups of wing plate structures 52 of the aluminum profile 5 are provided in this embodiment, the corresponding covering component 6 is also provided in two groups. The two groups of covering components 6 are respectively installed in the two cooling racks 41. The covering component 6 includes multiple groups of covering plates 61 arranged in a circular manner (each group of covering plates 61 is provided with two upper and lower ones), and the two covering plates 61 of each group are respectively arranged corresponding to the upper and lower sides of the wing plate structure 52. A circulating movement control component 7 and a heating component 8 are also installed inside the cooling rack 41. The circulating movement control component 7 is used to drive the upper and lower covering plates 61 of each group to approach and move away from the wing plate structure 52, and to drive the covering plates 61 to follow the aluminum profile when the covering plates 61 are in contact with the wing plate structure 52. The traction movement of the material 5 moves synchronously, and the heating component 8 is used to heat the covering plate 61 and increase the temperature of the covering plate 61 to the same temperature as the material when the aluminum profile 5 is just extruded. Specifically, when the aluminum profile 5 is extruded and enters the area inside the cooling rack 41, the heating component 8 preheats the covering plate 61, and the circulating movement control component 7 controls each group of covering plates 61 to approach the wing plate structure 52 in turn and fit the wing plate structure 52 and then move with the aluminum profile 5, and the covering plates 61 are moved together to the water cooling area of the water cooling component 42 while remaining covered on the outside of the wing plate structure 52 for cooling. After the cooling is completed, the circulating movement control component 7 controls each group of covering plates 61 to move away from the wing plate structure 52 in turn and return to the initial position for reuse (due to the large number of covering plates 61, they can be recycled, and during the recycling process, there will always be multiple groups of covering plates 61 covering the outside of the wing plate structure 52 at the same time).

[0044] It should be noted that the cladding plate 61 is a thin-walled metal structure adapted to the shape of the wing plate structure 52, and the hardness of the cladding plate 61 is higher than the hardness of the wing plate structure 52 at the same temperature. For example, a steel cladding plate 61 is used, and the cladding plate 61 is preheated to keep it consistent with the temperature of the aluminum profile 5 before cooling, and then passes through the water cooling area of the water cooling component 42 together with the aluminum profile 5. At this time, the tubular body 51 directly contacts the water for cooling, but because the air temperature inside the tubular body 51 is higher, the cooling rate of the tubular body 51 is lower than the cooling rate when both sides contact water at the same time, and the outside of the wing plate structure 52 is covered with the cladding plate 61, which is equivalent to increasing the thickness. Therefore, when contacting water, it can be slightly cooled. The cooling rate of the wing plate structure 52 is slightly slowed down, thereby relatively reducing the water cooling rate difference between the wing plate structure 52 and the tubular body 51, thereby reducing the uneven deformation of the wing plate structure 52. Even if the wing plate structure 52 is likely to be deformed due to the material itself or processing errors, since the covering plate 61 covers both sides of the wing plate structure 52 during the water cooling operation, the wing plate structure 52 is clamped and positioned, which further avoids the irregular deformation of the wing plate structure 52, thereby greatly improving the product qualification rate of the aluminum profile 5 with the wing plate structure 52, reducing the scrap rate, thereby improving product quality, reducing material waste, and greatly improving the processing accuracy and practicality of the manufacturing device.

[0045] Further, refer to the instructions attached Figure 3 and Figure 4 In this embodiment, the water-cooling component 42 adopts a spray-type water cooling device, that is, the water-cooling component 42 includes multiple groups of spray heads 421, and the spray heads 421 are installed on the cooling rack 41, and a water tank 43 is provided at the bottom of the cooling processing space between the two groups of cooling racks 41. A recovery water pipe is installed on the water tank 43. Multiple groups of spray heads 421 form a water spray structure arranged around the aluminum profile 5, and evenly spray cold water to the surface of the aluminum profile 5. In addition, the water-cooling component 42 of this embodiment can also be in the form of a cooling water tank, that is, a corresponding water tank structure is provided, so that the aluminum profile 5 and the cladding plate 61 pass through the water in the water tank and contact with the water for cooling. Since this type of cooling scheme is a commonly used scheme in aluminum profile extrusion molding production, this embodiment will not be explained in detail.

[0046] In the above embodiment, the circulating movement control component 7 is a crawler-type circulating movement control component, that is, the circulating movement control component 7 includes a track shoe 71, a track wheel 72 and an installation box 73. The installation box 73 is fixedly installed in the cooling rack 41 and is used to separate and protect the track shoe 71 and the track wheel 72. The track shoe 71 is provided in plurality, and the plurality of track shoes 71 are hinged in sequence to form a track structure. There are at least two groups of track wheels 72, which are used to support the track structure formed by the track shoes 71. One group of track wheels 72 is driven to rotate by a motor, and each group of covering plates 61 is respectively installed Installed on the corresponding track plate 71, the two covering plates 61 of each group are distributed up and down on the track plate 71, so that the covering plates 61 are circulated and driven by means of the track structure formed by the track plate 71, and the heating component 8 is arranged inside the installation box 73. The covering plates 61 are first heated by the heating component 8 and then rotated to the initial position. Under the circulatory drive of the track plate 71, they gradually cover the wing plate structure 52 and move synchronously with the aluminum profile 5. The heating component 8 can use high-efficiency heating equipment such as flame heating or eddy current heating to quickly heat the covering plates 61.

[0047] Refer to the instruction manual Figures 5 and 6 When the wing plate structure 52 is a uniform straight structure, the covering plate 61 can be directly fixed on the track plate 71. When the two covering plates 61 of each group gradually approach the wing plate structure 52 through the arc area formed by the track wheel 72, the wing plate structure 52 can directly enter the space between the upper and lower covering plates 61. For some aluminum profiles 5, in order to adapt to the actual use scenario, certain protrusion structures such as arc grooves, reinforcing ribs, etc. will be provided on the wing plate structure 52. Please refer to the attached manual for details. Figure 8 At this time, the wing plate structure 52 cannot be directly inserted into the area between the upper and lower covering plates 61. Therefore, this embodiment also provides the following technical solutions. Specifically, a guide structure 62 (such as a guide rail structure) is provided on the track plate 71, and the covering plate 61 is slidably set on the track plate 71 through the guide structure 62. The covering assembly 6 also includes a moving drive assembly for driving the two groups of covering plates 61 to approach or move away from each other. When the cyclic movement control assembly 7 drives the corresponding group of covering plates 61 to approach the wing plate structure 52, the two covering plates 61 of the group are separated in advance, that is, the distance between the upper and lower covering plates 61 is increased to ensure that when the covering plate 61 approaches the wing plate structure 52, the wing plate structure 52 can smoothly enter the area between the upper and lower covering plates 61, and then the two groups of covering plates 61 are driven by the moving drive assembly to approach the wing plate structure 52 and contact the wing plate structure 52 to cover it, thereby being able to adapt to the shapes of various wing plate structures 52.

[0048] For details, please refer to the attached manual. Figure 8 and Figure 9The mobile drive assembly includes two sets of guide frames 64, which are fixedly mounted on the cooling rack 41, and the two sets of guide frames 64 are respectively arranged in the upper and lower areas of each set of covering plates 61. A restriction area is formed between the two sets of guide frames 64, and a reset elastic member 63 (such as a spring) is installed between the upper and lower covering plates 61 of each group. The covering plate 61 is provided with a pressure contact portion 65 at a position corresponding to the restriction area of the guide frame 64. The pressure contact portion 65 slides in the restriction area. Figure 9 , the two ends of the restriction area of the guide frame 64 are set to be open. Before the upper and lower covering plates 61 of each group enter the restriction area of the guide frame 64, the pressure contact portion 65 does not contact the guide frame 64, so it can be in a separated state. That is to say, when the upper and lower covering plates 61 of each group gradually move to the outside of the wing plate structure 52 and gradually move away from the external area of the wing plate structure 52, the upper and lower covering plates 61 are in a separated state. Therefore, at this time, the distance between the upper and lower covering plates 61 is large, which can allow the wing plate structure 52 to enter or move out relative to each other. In the remaining stages, after the covering plates 61 gradually enter the restriction area, the pressure contact portion 65 contacts the guide frame 64. The upper and lower covering plates 61 are close to each other and tightly attached to the wing plate structure 52 by the guide frame 64, so that the upper and lower covering plates 61 of the corresponding group are close to each other and tightly attached to the wing plate structure 52, thereby realizing that the upper and lower covering plates 61 of the corresponding group are in a separated state when they are initially close to the wing plate structure 52, and when the covering plates 61 completely reach the outside of the wing plate structure 52, the upper and lower covering plates 61 approach each other and cover the wing plate structure 52, and then follow the wing plate structure 52 to enter the water cooling area synchronously. After the aluminum profile 5 is cooled, when the covering plates 61 need to leave the wing plate structure 52, the upper and lower covering plates 61 first move away from each other in the vertical direction to increase the space between them, and then move away from the wing plate structure 52 at the same time.

[0049] In the above embodiment, in addition to using the guidance of the guide frame 64 to enable the covering plate 61 to adapt to the wing plate structure 52 more conveniently, the extrusion force of the covering plate 61 on the wing plate structure 52 can also be controlled by reasonably setting the size of the restricted area of the guide frame 64 during the cooling process, thereby realizing the deformation protection function of the wing plate structure 52 while also forming a certain clamping force on the wing plate structure 52, and then using the circular movement control component 7 to drive the covering plate 61, a traction force is formed on the aluminum profile 5 in the area near the aluminum profile extruder 1, thereby cooperating with the mobile traction machine 3 to perform a more stable traction operation on the aluminum profile 5, and the traction formed by the covering plate 61 is relatively close to the aluminum profile extruder 1, which can avoid the problem of uneven traction force caused by the increase in the length of the aluminum profile 5 when the mobile traction machine 3 gradually moves away, thereby avoiding the problem of uneven stress of the pulled aluminum profile 5, and further improving the product quality of the aluminum profile 5.

[0050] In addition, since the covering plate 61 and the wing plate structure 52 are water-cooled together, the covering plate 61 and the wing plate structure 52 will shrink to a certain extent after cooling. At this time, if the spacing of the covering plate 61 is not adjusted, a gap will be formed between the covering plate 61 and the wing plate structure 52. Although the cooling has been completed at this time and will not affect the product quality of the aluminum profile 5, the existence of the gap will reduce the traction effect of the covering plate 61 on the wing plate structure 52. For this reason, the present embodiment also provides the following technical solutions. Specifically, multiple sets of guide pressure wheels 66 are rotatably installed on the guide frame 64. The guide pressure wheels 66 are in rolling cooperation with the pressure contact portion 65. A rubber layer is provided on the outside of the guide pressure wheel 66. When the guide pressure wheel 66 contacts the pressure contact portion 65, an extrusion deformation is formed on the rubber layer.

[0051] It should be noted that the above-mentioned guide pressure wheel 66 is arranged near the water-cooling area, that is, the covering plate 61 passing through the water-cooling area will cooperate with the rubber layer of the guide pressure wheel 66, so the rubber layer will not be affected by high temperature. Since the rubber layer is in an extruded state, it can form a higher extrusion elastic force on the covering plate 61, thereby ensuring that after cooling down in the water-cooling area, before the covering plate 61 leaves the wing plate structure 52, the covering plate 61 can provide effective pressure on the wing plate structure 52 to ensure the auxiliary traction effect on the aluminum profile 5.

[0052] Furthermore, in the above embodiment, due to many uncontrollable factors in the production process, such as impurities in the aluminum material itself and residues of some materials during the processing, an impurity layer is easily formed on the surface of the aluminum profile 5 after extrusion. Especially after being cooled in water, the impurity layer on the surface of the aluminum profile 5 is deformed and detached due to the different shrinkage rates of the material. The detached impurities are easy to adhere to the surface of the cladding plate 61. If they are not cleaned in time, the impurities in the cladding plate 61 will cause excessive extrusion when they subsequently contact the wing plate structure 52 behind, thereby increasing the product defect rate. For this reason, this embodiment also provides the following simple cleaning solution. For details, please refer to the attached manual. Figure 10 A cleaning component for cleaning the surface of the covering plate 61 is provided in the installation box 73. The cleaning component includes a cleaning air pipe 9. The cleaning air pipe 9 is fixedly installed in the installation box 73, and the cleaning air pipe 9 is located in the heating area of the heating component 8. The cleaning air pipe 9 is connected to the high-pressure air pump through a pipeline. The output end of the cleaning air pipe 9 corresponds to the area between the upper and lower covering plates 61. In actual use, when the covering plate 61 reaches the heating component 8 and is heated, the moisture evaporates and impurities no longer adhere. The cleaning can be achieved by blowing air with the cleaning air pipe 9. Among them, the area corresponding to the cleaning air pipe 9 in the installation box 73 can also be provided with a corresponding impurity collection box or a vacuum cleaner and other equipment to collect the blown-away impurities.

[0053] Further, refer to the instructions attached Figure 11 and Figure 12The output end of the cleaning air pipe 9 is arranged near the track shoe 71, and a back-blowing end cap 91 is rotatably installed on the output end of the cleaning air pipe 9. The back-blowing end cap 91 is a conical structure, and the opening of the back-blowing end cap 91 is located in the outer wall area of the cleaning air pipe 9, that is, the opening of the back-blowing end cap 91 is arranged away from the track shoe 71. An output channel away from the track shoe 71 is formed between the opening of the back-blowing end cap 91 and the outer wall of the cleaning air pipe 9, and a plurality of sets of blade plates 92 are fixedly connected to the inner wall of the opening of the back-blowing end cap 91. When the cleaning air pipe 9 blows out the airflow, the airflow can be blown out in the opposite direction from the opening of the back-blowing end cap 91, and the blowing range is larger, so that the inner sides of the upper and lower covering plates 61 can be effectively cleaned at the same time, and under the action of the blade plates 92, the back-blowing end cap 91 can automatically rotate when blowing, so that the blown airflow can fluctuate, thereby further improving the blowing and cleaning effect.

[0054] Refer to the instruction manual Figure 13 Based on the above manufacturing device, the present invention also provides a high-elongation aluminum extrusion manufacturing process, comprising the following steps:

[0055] Step 1: Place the preheated aluminum rod into the inner cavity of the aluminum profile extruder 1, and apply pressure to the aluminum rod in the inner cavity through the extrusion equipment to extrude the aluminum from the corresponding die, thereby forming a continuous aluminum profile 5;

[0056] Step 2: Pass the initially extruded aluminum profile 5 through the area between the two cooling racks 41 , and pass the wing plate structure 52 through the corresponding cladding plate 61 , and then through the water cooling area of the water cooling assembly 42 ;

[0057] Step 3: Clamp the end of the aluminum profile 5 by the clamping mechanism in the mobile tractor 3, and drive the mobile tractor 3 to move and tract it, and cooperate with the extrusion equipment on the aluminum profile extruder 1 to continue to apply pressure and continue to extrude. At the same time, the aluminum profile conveying assembly 2 supports and conveys the pulled aluminum profile 5;

[0058] Step 4: Heat the cladding plate 61 by the heating assembly 8 so that the temperature of the cladding plate 61 is the same as the temperature of the aluminum profile 5 when it is extruded;

[0059] Step 5: The upper and lower covering plates 61 of the corresponding group are driven by the cyclic movement control component 7 to approach the wing plate structure 52, and then adhere to the wing plate structure 52 to form a cover. After that, they follow the movement of the aluminum profile 5 and enter the water cooling area of the water cooling component 42 for cooling.

[0060] Step 6: After cooling is completed, the circular movement control assembly 7 controls the upper and lower covering plates 61 of the corresponding group to move away from the wing plate structure 52 and return to the initial position to wait for use.

[0061] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
