Description

Technical Field

[0001] The present invention relates to the technical field of extrusion forming manufacturing, and more specifically, the present invention relates to an aluminum extrusion manufacturing device and process with high elongation rate. Background Art

[0002] Aluminum profile extrusion forming is a technology that extrudes aluminum alloy through a die to form a desired cross-sectional shape. This technology utilizes the plasticity of metals to plastically deform aluminum alloy under high temperature and pressure, thereby obtaining products with specific cross-sectional shapes and dimensions. Its main process is to heat the aluminum rod to a suitable extrusion temperature, generally between 450°C and 500°C, and then push the heated aluminum rod through the die by a powerful hydraulic system to obtain the desired cross-sectional shape.

[0003] Since the extruded aluminum material is at a high temperature, in order to prevent the growth of material grains, control the microstructure of the material, and make the material reach the ideal hardness and strength, it is necessary to cool the extruded material in a timely manner. Among them, for some high-quality aluminum alloy profiles, their ductility is higher, so they are easier to form and are therefore widely used. However, in the actual processing process, because such materials are in a high-temperature state when extruded and their ductility is high, the material is relatively softer. Therefore, in order to avoid the occurrence of secondary stretching of the material during the process of the traction device pulling the material (the error between the pulling speed of the traction device and the material extrusion speed of the extrusion device) and the bending of the material itself (the material produces a hanging bend when passing through the suspended area due to its own gravity), it is necessary to perform efficient and rapid cooling when the material is extruded from the extrusion device, such as water cooling (spraying cold water on the material or making the material pass through a water tank), to ensure that the extruded material can quickly harden to avoid accidents.

[0004] During the extrusion of aluminum profiles, for materials with regular and uniform cross-sectional shapes, such as quadrilateral tubes, profiles with the same protruding structures on all four sides, etc., during actual cooling, due to the uniform structure of the material, the temperature reduction speed and cooling effect of each region of the material are not very different during temperature reduction, so the temperature difference deformation caused is almost negligible. However, for some aluminum profile structures, in addition to having a tubular main structure, flat wing plate structures extending outward are provided on both sides or multiple sides outside the tube (which act as the bottom plate or for installation and support during the use of the profile).

[0005] For this type of aluminum profile, its outer wing plates are in a suspended state, that is, there is no obstruction. During the rapid cooling process, both sides of the wing plates can come into contact with the cooling medium (water) simultaneously, and the cooling speed is relatively fast. However, the air inside the tubular main body structure is in a high-temperature state. Therefore, affected by the high-temperature air inside, the cooling speed of the tubular main body structure is relatively slow, resulting in a temperature change difference, which in turn causes a cooling shrinkage deformation difference between the wing plates and the tubular main body structure, and further leads to the wing plates being prone to irregular deformations (such as wavy deformations at the edges of the wing plates), affecting the actual forming quality and forming accuracy of the material. Summary of the Invention

[0006] A high-elongation aluminum extrusion manufacturing device and process provided by the present invention aim to solve the following problem: When the existing aluminum profile with suspended outer wing plates is cooled after the material is extruded in the extrusion forming process, the cooling speed on both sides of the wing plates is relatively fast, resulting in a cooling shrinkage deformation difference between the wing plates and the tubular main body structure, and further leading to the wing plates being prone to irregular deformations, affecting the actual forming quality and forming accuracy of the material.

[0007] To achieve the above object, the present invention provides the following technical solution: A high-elongation aluminum extrusion manufacturing device includes an aluminum profile extruder, an aluminum profile conveying assembly, a moving tractor, and a cooling assembly. The cooling assembly is arranged at the output end of the aluminum profile extruder; The cooling assembly includes two cooling frames. A water cooling assembly is arranged between the two cooling frames. At the position corresponding to the wing plate structure in the cooling frames, a covering assembly is arranged; The covering assembly includes multiple groups of covering plates arranged in a cycle. Each group of covering plates has two, one upper and one lower. A cycle moving control assembly and a heating assembly are also installed inside the cooling frames. The cycle moving 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 in contact with the wing plate structure. The heating assembly is used to heat the covering plates.

[0008] In a preferred embodiment, the two covering plates of each group are respectively arranged corresponding to the upper and lower surfaces of the wing plate structure. The covering plates are plate-shaped metal structures adapted to the shape of the wing plate structure, and the hardness of the covering plates is higher than that of the wing plate structure at the same temperature.

[0009] In a preferred embodiment, the cycle moving control assembly is a track-type cycle moving control assembly. The cycle moving control assembly includes track plates, track wheels, and an installation box. The installation box is fixedly installed in the cooling frames. The track plates and track wheels are arranged in the installation box. The track plates are provided in multiple numbers, and the multiple track plates are sequentially hinged to form a track structure. The track wheels are used to support the track structure formed by the track plates, and the track wheels have rotational power. Each group of covering plates is respectively installed on the corresponding track plates.

[0010] In a preferred embodiment, a guiding structure is provided on the crawler plate, and the covering plate is slidably arranged on the crawler plate through the guiding structure. The covering assembly further includes a moving driving assembly for driving two groups of covering plates to approach or move away from each other.

[0011] In a preferred embodiment, the moving driving assembly includes two groups of guiding frames. The two groups of guiding frames are fixedly installed on the cooling frame, and the two groups of guiding frames are respectively arranged corresponding to the upper and lower regions of each group of covering plates. A limiting area is formed between the two groups of guiding frames. A reset elastic member is installed between the upper and lower covering plates of each group. The covering plate is provided with a pressing contact portion corresponding to the limiting area of the guiding frame, and both ends of the limiting area of the guiding frame are arranged in an open shape.

[0012] In a preferred embodiment, a plurality of guiding pressure wheels are also rotatably installed on the guiding frame. The guiding pressure wheels are in rolling cooperation with the pressing contact portion. A rubber layer is arranged on the outside of the guiding pressure wheels. When the guiding pressure wheels contact the pressing contact portion, extrusion deformation is formed on the rubber layer.

[0013] In a preferred embodiment, a cleaning assembly is arranged in the installation box. The cleaning assembly 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 assembly. The cleaning air pipe is connected to a high-pressure air pump through a pipeline. The output end of the cleaning air pipe is arranged corresponding to the area between the upper and lower covering plates.

[0014] In a preferred embodiment, the output end of the cleaning air pipe is arranged close to the crawler plate. A reverse blowing end cap is rotatably installed on the output end of the cleaning air pipe. The reverse blowing end cap is of a conical structure, and the opening of the reverse blowing end cap is located in the outer wall area of the cleaning air pipe. An output channel deviating from the crawler plate direction is formed between the opening of the reverse blowing end cap and the outer wall of the cleaning air pipe, and a plurality of vane plates are fixedly connected in the inner wall of the opening of the reverse blowing end cap.

[0015] In a preferred embodiment, the water cooling assembly is a spray type water cooling device. The water cooling assembly includes a plurality of spray heads. The spray heads are installed on the cooling frame. A water tank is arranged at the bottom of the cooling treatment space between the two cooling frames. A recovery water pipe is installed on the water tank. The plurality of spray heads form a water spraying structure surrounding the aluminum profile.

[0016] A manufacturing process for extruding aluminum materials with high elongation includes the following steps: Step 1: Put 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, so that the aluminum material is extruded from the corresponding die, thereby forming a continuous aluminum profile; Step 2: Pass the initially extruded aluminum profile through the area between the two cooling frames, pass the wing plate structure through the corresponding covering plate, and then pass through the water cooling area of the water cooling assembly; Step 3: Clamp the end of the aluminum profile through the clamping mechanism in the mobile tractor, drive the mobile tractor to move and tow it, and cooperate with the continuous pressure of the extrusion equipment on the aluminum profile extruder to continuously extrude; Step 4: Heat the cladding plate through the heating component so that the temperature of the cladding plate is the same as the temperature when the aluminum profile is extruded; Step 5: Drive the upper and lower cladding plates of the corresponding group to approach the wing plate structure through the circulating movement control component, fit with the wing plate structure to form a cover, and then enter the water cooling area of the water cooling component synchronously following the movement of the aluminum profile for cooling; Step 6: After cooling is completed, the circulating 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 for waiting to be used.

[0017] The beneficial effects of the present invention are as follows: The present invention clads through the setting of the cladding plate and the wing plate structure, and then follows the aluminum profile through the water cooling area of the water cooling component. At this time, the tubular main body directly contacts water for cooling and temperature reduction. However, since the air temperature inside the tubular main body is relatively high, the cooling rate of the tubular main body is lower than the cooling rate when both sides are in contact with water simultaneously. And since the outside of the wing plate structure is covered with the cladding plate, which is equivalent to increasing the thickness, when contacting water, it can slightly slow down the cooling rate of the wing plate structure. Thus, relatively reduce the water cooling temperature difference between the wing plate structure and the tubular main body, and further reduce the uneven deformation generated by the wing plate structure. Even when there is a possibility of deformation of the wing plate structure due to the material itself or processing errors, during the water cooling operation process, since the cladding plate covers both sides of the wing plate structure throughout the process, it forms a clamping and positioning for the wing plate structure, further avoiding the generation of irregular deformation of the wing plate structure. Thereby, it greatly improves the product qualification rate of aluminum profiles with wing plate structures, reduces the waste rate, further improves the product quality, reduces material waste, and greatly improves the processing accuracy and practicality of the manufacturing device.

Detailed implementation manners

[0032] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0033] Refer to the attached drawings of the specification Figures 1 to 12, an aluminum extrusion manufacturing device with a high elongation rate, comprising an aluminum profile extruder 1, an aluminum profile conveying assembly 2, a mobile tractor 3, and a cooling assembly 4. The aluminum profile extruder 1 is used to apply pressure to the aluminum rod input into its inner cavity, so that the aluminum material is extruded from the corresponding die, thereby forming a continuous aluminum profile 5. A clamping mechanism is provided in the mobile tractor 3 to clamp the end of the aluminum profile 5 and pull the aluminum profile 5 to move, cooperating with the continuous extrusion and discharging inside the aluminum profile extruder 1 to form the traction of the aluminum profile 5 and make the aluminum profile 5 be conveyed on the aluminum profile conveying assembly 2. The cooling assembly 4 is arranged at the output end of the aluminum profile extruder 1 (i.e., the position where the aluminum profile 5 is extruded). The cooling assembly 4 includes two cooling frames 41. The area between the two cooling frames 41 is (cooling treatment space). After the aluminum profile 5 is extruded, it passes through the area between the two cooling frames 41 and then is led to the aluminum profile conveying assembly 2. A water cooling assembly 42 is arranged between the two cooling frames 41, and the area covered by the water cooling assembly 42 is the water cooling area. When the aluminum profile 5 passes through the area between the two cooling frames 41, it passes through the water cooling area of the water cooling assembly 42 for rapid cooling, temperature reduction, and shaping.

[0034] It should be noted that the above-mentioned aluminum profile extruder 1, aluminum profile conveying assembly 2, and mobile tractor 3 are all common equipment in the aluminum profile production process, and their specific structures are not elaborated in this embodiment. Other related equipment such as the cutting of aluminum profiles and the alternating replacement of the mobile tractor 3 are also prior arts and are not described in this embodiment.

[0035] In fact, the aluminum profile 5 is composed of a tubular main body 51 and a wing plate structure 52. In this embodiment, two sets of wing plate structures 52 are provided, and the two sets of wing plate structures 52 are symmetrically arranged on both sides of the tubular main body 51. At the position corresponding to the wing plate structure 52 in the cooling rack 41, a covering component 6 is provided. Based on the fact that there are two sets of wing plate structures 52 of the aluminum profile 5 in this embodiment, accordingly, two sets of covering components 6 are also provided. The two sets of covering components 6 are respectively installed in two cooling racks 41. The covering component 6 includes multiple sets of covering plates 61 arranged in a cycle (each set of covering plates 61 has two, one above and one below). The two covering plates 61 of each set are respectively arranged corresponding to the upper and lower surfaces of the wing plate structure 52. Inside the cooling rack 41, a cyclic movement control component 7 and a heating component 8 are also installed. The cyclic movement control component 7 is used to drive the upper and lower two covering plates 61 of each group to approach and move away from the wing plate structure 52, and when the covering plates 61 are in contact with the wing plate structure 52, drive the covering plates 61 to move synchronously following the traction movement of the aluminum profile 5. The heating component 8 is used to heat the covering plates 61 and raise the temperature of the covering plates 61 to be the same as the temperature of 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 pre-heats the covering plates 61, and the cyclic movement control component 7 controls each group of covering plates 61 to approach the wing plate structure 52 in sequence and move together with the aluminum profile 5 after being in contact with the wing plate structure 52. And the covering plates 61 move together to the water cooling area of the water cooling component 42 for cooling while remaining covering the outside of the wing plate structure 52. After the cooling is completed, the cyclic movement control component 7 then controls each group of covering plates 61 to move away from the wing plate structure 52 in sequence and return to the initial position for reuse (since there are many covering plates 61, a cycle of use can be formed, and during the cycle of use, there will always be multiple sets of covering plates 61 covering the outside of the wing plate structure 52).

[0036] 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 that 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 pre-heated to keep the same temperature as that of the aluminum profile 5 before it cools. Subsequently, it passes through the water-cooling area of the water-cooling component 42 together with the aluminum profile 5. At this time, the tubular main body 51 directly contacts the water for cooling. However, since the air temperature inside the tubular main body 51 is relatively high, the cooling rate of the tubular main body 51 is lower than the cooling rate when both sides are in contact with water simultaneously. Since the outside of the wing plate structure 52 is covered with the cladding plate 61, which is equivalent to increasing the thickness, when in contact with water, it can slightly slow down the cooling rate of the wing plate structure 52, thereby relatively reducing the water-cooling temperature difference between the wing plate structure 52 and the tubular main body 51, and further reducing the uneven deformation generated by the wing plate structure 52. Even when there is a possibility of deformation of the wing plate structure 52 due to the material itself or processing errors, during the water-cooling operation, since the cladding plate 61 covers both sides of the wing plate structure 52 throughout the process, it forms a clamping and positioning for the wing plate structure 52, further avoiding the irregular deformation of the wing plate structure 52, thus greatly improving the product qualification rate of the aluminum profile 5 with the wing plate structure 52, reducing the waste rate, further improving the product quality, reducing material waste, and greatly improving the processing accuracy and practicality of the manufacturing device.

[0037] Furthermore, referring to the attached drawings of the specification Figure 3 and Figure 4 In this embodiment, the water-cooling component 42 adopts a spray water-cooling device, that is, the water-cooling component 42 includes multiple groups of spray heads 421. The spray heads 421 are installed on the cooling rack 41, and a water tank 43 is provided at the bottom of the cooling treatment space between the two groups of cooling racks 41. A recovery water pipe is installed on the water tank 43. The multiple groups of spray heads 421 form a water spraying structure surrounding the aluminum profile 5 and uniformly spray cold water onto the surface of the aluminum profile 5. In addition, the water-cooling component 42 of this embodiment can also adopt the form of a cooling water tank, that is, a corresponding water tank structure is set so that the aluminum profile 5 and the cladding plate 61 pass through the water in the water tank and contact the water for cooling. Since this type of cooling solution is a common solution in the production of aluminum profile extrusion molding, it will not be elaborated in this embodiment.

[0038] In the above-described embodiment, the cyclic movement control component 7 is a crawler-type cyclic movement control component. That is, the cyclic movement control component 7 includes crawler plates 71, crawler wheels 72, and a mounting box 73. The mounting box 73 is fixedly installed in the cooling frame 41 and is used to separate and protect the crawler plates 71 and the crawler wheels 72. A plurality of crawler plates 71 are provided, and the plurality of crawler plates 71 are sequentially hinged to form a crawler structure. At least two sets of crawler wheels 72 are provided, and the crawler wheels 72 are used to support the crawler structure formed by the crawler plates 71. One set of crawler wheels 72 is driven to rotate by a motor, and each group of covering plates 61 is respectively installed on the corresponding crawler plate 71. The two covering plates 61 of each group are distributed vertically on the crawler plate 71. Thus, by means of the crawler structure formed by the crawler plates 71, the covering plates 61 are cyclically driven. The heating component 8 is arranged inside the mounting box 73. The covering plates 61 are first heated by the heating component 8 and then rotate back to the initial position, and gradually cover the wing plate structure 52 and move synchronously with the aluminum profile 5 under the cyclic drive of the crawler plates 71. Among them, the heating component 8 can adopt a scheme of high-efficiency heating equipment such as flame heating or eddy current heating to quickly heat the covering plates 61.

[0039] Refer to the attached drawings of the specification Figures 5 to 6 When the wing plate structure 52 is a uniform flat structure, the covering plates 61 can be directly fixedly installed on the crawler plates 71. When the two covering plates 61 of each group gradually approach the wing plate structure 52 through the arc area formed by the crawler wheels 72, the wing plate structure 52 can directly enter the space between the upper and lower two covering plates 61. For some aluminum profiles 5, in order to adapt to the actual use scenario, certain convex structures such as arc grooves and reinforcing ribs are also provided on the wing plate structure 52. Refer to the attached drawings of the specification Figure 8 At this time, the wing plate structure 52 cannot be directly inserted into the area between the upper and lower two covering plates 61. Therefore, the present embodiment also provides the following technical solution. Specifically, a guiding structure 62 (such as a guide rail structure) is provided on the crawler plate 71, and the covering plates 61 are slidably arranged on the crawler plate 71 through the guiding structure 62. The covering component 6 further includes a moving drive component for driving the two groups of covering plates 61 to approach or move away from each other. When the cyclic movement control component 7 drives the corresponding group of covering plates 61 to approach the wing plate structure 52, the two covering plates 61 of this group are separated in advance, that is, the distance between the upper and lower two covering plates 61 is increased, so as to ensure that the wing plate structure 52 can smoothly enter the area between the upper and lower two covering plates 61 when the covering plates 61 approach the wing plate structure 52. Then, the moving drive component drives the two groups of covering plates 61 to approach the wing plate structure 52 and contact the wing plate structure 52 for covering, so as to be able to adapt to the shapes of various wing plate structures 52.

[0040] Specifically, refer to the attached drawings of the specification Figure 8 and Figure 9, The moving drive assembly includes two sets of guide frames 64, which are fixedly installed on the cooling frame 41. The two sets of guide frames 64 are respectively arranged corresponding to the upper and lower regions of each group of covering plates 61. A restricted area is formed between the two sets of guide frames 64. 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 pressing contact portion 65 at a position corresponding to the restricted area of the guide frame 64. The pressing contact portion 65 is slidably engaged within the restricted area. Refer to the attached Figure 9 , Both ends of the restricted area of the guide frame 64 are arranged in an open shape. Before the upper and lower covering plates 61 of each group enter the restricted area of the guide frame 64, the pressing contact portion 65 does not contact the guide frame 64. Therefore, they 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 outside area of the wing plate structure 52, the upper and lower covering plates 61 are in a separated state. Therefore, the distance between the upper and lower covering plates 61 is relatively large at this time, allowing the wing plate structure 52 to enter or move out relatively. In other stages, after the covering plate 61 gradually enters the restricted area, the pressing contact portion 65 contacts the guide frame 64 and is squeezed by the guide frame 64, which can make the upper and lower covering plates 61 approach each other and closely adhere to the wing plate structure 52. Thus, when the upper and lower covering plates 61 of the corresponding group initially approach the wing plate structure 52, they are in a separated state. When the covering plate 61 completely reaches 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 enter the water cooling area synchronously with the wing plate structure 52. After the aluminum profile 5 is cooled, when the covering plate 61 needs to leave the wing plate structure 52, the upper and lower covering plates 61 first move away vertically to increase the space between them, and then move away from the wing plate structure 52 simultaneously.

[0041] In the above embodiment, in addition to enabling the covering plate 61 to be more conveniently adapted to the wing plate structure 52 by means of the guidance of the guide frame 64, during the cooling process, by reasonably setting the size of the restricted area of the guide frame 64, the pressing force of the covering plate 61 on the wing plate structure 52 can be controlled. Thus, while realizing the deformation protection function for the wing plate structure 52, a certain clamping force can also be formed on the wing plate structure 52. Furthermore, by means of the driving of the covering plate 61 by the cyclic movement control assembly 7, a traction force is formed on the aluminum profile 5 in the area near the aluminum profile extruder 1, so as to cooperate with the moving tractor 3 to perform a more stable traction operation on the aluminum profile 5. Moreover, 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 increasing length of the aluminum profile 5 when the moving tractor 3 gradually moves away, and further avoid the problem of uneven stress of the pulled aluminum profile 5, thereby further improving the product quality of the aluminum profile 5.

[0042] In addition, since the cladding plate 61 and the wing plate structure 52 are water-cooled together, both the cladding plate 61 and the wing plate structure 52 will undergo a certain degree of shrinkage after cooling. At this time, if the spacing of the cladding plate 61 is not adjusted, a gap will be formed between the cladding plate 61 and the wing plate structure 52. Although the cooling is completed at this time and it will not affect the product quality of the aluminum profile 5, due to the existence of the gap, the traction effect of the cladding plate 61 on the wing plate structure 52 will be reduced. Therefore, the present embodiment also provides the following technical solution. Specifically, a plurality of guiding pressure wheels 66 are rotatably installed on the guiding frame 64. The guiding pressure wheels 66 are in rolling cooperation with the pressing contact portion 65. A rubber layer is provided on the outer portion of the guiding pressure wheels 66. When the guiding pressure wheels 66 come into contact with the pressing contact portion 65, an extrusion deformation is formed on the rubber layer.

[0043] It should be noted that the above guiding pressure wheels 66 are arranged near the water-cooling area. That is to say, the cladding plate 61 passing through the water-cooling area will cooperate with the rubber layer of the guiding pressure wheels 66. Therefore, the rubber layer will not be affected by high temperature. And due to the extrusion state of the rubber layer, a relatively high extrusion elastic force can be formed on the cladding plate 61, so as to ensure that after the temperature of the cladding plate 61 is reduced through the water-cooling area and before the cladding plate 61 leaves the wing plate structure 52, the cladding plate 61 can provide an effective pressure on the wing plate structure 52 to ensure the auxiliary traction effect on the aluminum profile 5.

[0044] Furthermore, in the above implementation manner, during the production process, due to many uncontrollable factors, such as impurities in the aluminum material itself and residues of some materials during the processing, after the aluminum profile 5 is extruded, an impurity layer is likely to form on the surface. Especially after water-cooling, when the impurity layer on the surface of the aluminum profile 5 deforms and detaches due to different shrinkage rates of the materials, the detached impurities are likely to adhere to the surface of the cladding plate 61. If not cleaned in time, the impurities in the cladding plate 61 will cause excessive extrusion when contacting the subsequent wing plate structure 52, thereby increasing the product defect rate. Therefore, the present embodiment also provides the following simple cleaning solution. Specifically, referring to the attached Figure 10 drawing, a cleaning component for cleaning the surface of the cladding 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 is located in the heating area of the heating component 8. The cleaning air pipe 9 is connected to a high-pressure air pump through a pipeline. The output end of the cleaning air pipe 9 is arranged corresponding to the area between the upper and lower cladding plates 61. Thus, during actual use, when the cladding plate 61 reaches the heating component 8 and is heated, the water evaporates, and the impurities no longer adhere. By cooperating with the cleaning air pipe 9 to blow air for cleaning, the cleaning of the impurities can be achieved. Among them, a corresponding impurity collection box or a vacuum cleaner and other devices can be provided in the installation box 73 in the area corresponding to the cleaning air pipe 9 to collect the blown-off impurities.

[0045] Furthermore, referring to the attached Figure 11 and Figure 12, the output end of the cleaning air pipe 9 is arranged close to the crawler plate 71. A reverse blowing end cap 91 is rotatably installed on the output end of the cleaning air pipe 9. The reverse blowing end cap 91 is of a conical structure, and the opening of the reverse blowing end cap 91 is located in the outer wall area of the cleaning air pipe 9, that is, the opening of the reverse blowing end cap 91 is arranged away from the crawler plate 71. An output channel in the direction away from the crawler plate 71 is formed between the opening of the reverse blowing end cap 91 and the outer wall of the cleaning air pipe 9. A plurality of vane plates 92 are fixedly connected to the inner wall at the opening of the reverse blowing end cap 91. Thus, when the air flow is blown out from the cleaning air pipe 9, the air flow can be blown out reversely from the opening of the reverse blowing end cap 91, and the blowing range is larger. Thus, the inner sides of the upper and lower two covering plates 61 can be effectively cleaned at the same time. And under the action of the vane plates 92, the reverse blowing end cap 91 can rotate automatically when blowing air, so that the blown air flow can generate fluctuations, thereby further improving the blowing and cleaning effect.

At the same time, support and convey the pulled aluminum profile 5 through the aluminum profile conveying component 2; Step 4: Heat the covering plate 61 through the heating component 8 so that the temperature of the covering plate 61 is the same as the temperature when the aluminum profile 5 is extruded; Step 5: Drive the upper and lower two covering plates 61 of the corresponding group to approach the wing plate structure 52 through the circulating movement control component 7, fit with the wing plate structure 52 to form a covering, and then enter the water cooling area of the water cooling component 42 synchronously following the movement of the aluminum profile 5 for cooling; Step 6: After cooling, the circulating movement control component 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 for waiting to be used.
