A straightening device for aluminum profile processing

Abstract

The present invention discloses a straightening device for aluminum profile processing, aiming to solve the technical problem of low processing quality of existing aluminum profile straightening devices. The device includes a frame. In the present invention, the main stretching oil cylinder drives the moving trolley to move on the frame and the moving crossbeam, and the trolley drives the stretching clamp head to clamp and straighten the aluminum profile. However, when straightening, the surface coating of the aluminum profile will break and splash onto the surface and inner corners. The rotating seat drives the double-pass air flow mechanism to first rotate horizontally by 90 degrees to form a cross shape with the profile, and the blocking block blocks the outer hole. The compression mechanism supplies air through the direct injection cavity to process the outer surface of the profile. Then the rotating seat rotates back 90 degrees to make the two in a linear shape, and the blocking block blocks the direct injection cavity, and the gas sprays out from the outer hole. At the same time, the lifting mechanism drives the tool lip to insert into the profile groove to process the inner corner. The aluminum profile straightening device of the present invention can synchronously clean the surface and inner corners of the aluminum profile during the straightening process, avoiding additional secondary cleaning operations after straightening, and improving the processing quality and production efficiency of the aluminum profile.

Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile processing, and more specifically, to a straightening device for aluminum profile processing. Background Art

[0002] In the field of aluminum profile processing, the straightening process is a key link to ensure the geometric shape and dimensional accuracy of aluminum profiles. With the wide application of aluminum profiles in industries such as construction, automotive, and aerospace, the market has increasingly stringent requirements for the quality and appearance of aluminum profiles.

[0003] Currently, many problems have emerged in the actual use of existing aluminum profile straightening devices, severely restricting the quality and efficiency of aluminum profile processing. First of all, during the straightening process, since the aluminum profile will deform, it is extremely easy to cause the surface coating to crack and powder. This not only affects the appearance quality of the aluminum profile, reducing the market competitiveness of the product, but also requires additional secondary cleaning operations after straightening, greatly increasing the processing cost and time cost.

[0004] Secondly, in the processing technology of aluminum profiles before straightening, it is usually necessary to pass through water or reagents, which will inevitably leave water marks on the surface and in the grooves of the aluminum profile. The traditional methods for dealing with water marks and dust have obvious limitations. On the one hand, they cannot effectively handle the dust and water marks in the dead space of the aluminum profile grooves. These residual substances will affect the subsequent use performance of the aluminum profile. For example, when used in the construction field, it may lead to a decrease in the corrosion resistance of the profile. On the other hand, the existing water mark treatment methods have poor effects and cannot meet the increasingly high quality standards. For example, in the manufacturing of automotive parts with extremely high surface quality requirements, the residual water marks will seriously affect the aesthetics and overall quality of the product. In summary, the existing aluminum profile straightening devices and related treatment technologies can no longer meet the needs of industry development. In view of this, we propose a straightening device for aluminum profile processing. Summary of the Invention

[0005] The purpose of the present invention is to provide a straightening device for aluminum profile processing to solve the technical problem of the low processing quality of existing aluminum profile straightening devices.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A straightening device for aluminum profile processing, including a frame, a moving crossbeam is arranged on the frame, a main stretching oil cylinder is arranged at one end of the frame, a moving trolley is slidably arranged on the frame and the moving crossbeam, one end of the moving trolley is connected to the output end of the main stretching oil cylinder, a stretching clamp head is arranged on the moving trolley, a lifting mechanism is arranged at the end of the moving trolley away from the main stretching oil cylinder, a bearing plate is arranged at the moving end of the lifting mechanism, a compression mechanism is arranged at one end of the bearing plate, a rotating seat is arranged at the other end of the bearing plate, and a double-pass air flow mechanism is arranged on the rotating seat;

[0007] The double-pass air flow mechanism includes a lip body assembly and a plugging block. The lip body assembly includes a knife lip, a direct injection cavity, an inner groove and an outer hole.

The side plates are symmetrically arranged on the cavity shell. One end of the input pipe is connected to the end of the telescopic hose away from the compression mechanism. The other end of the input pipe is connected to the side plate and communicates with the cavity shell. The output holes are linearly and equidistantly opened at the top end of the cavity shell. The knife lips are symmetrically arranged at the top end of the cavity shell. The rotary blowing assemblies are arranged at the positions of the output holes at the top end of the cavity shell.

[0012] Preferably, an inclined surface A and an inclined surface B are provided at one end of the inner groove close to the outer hole. The inclined surface A is located at the position inside the inner groove close to the top end of the outer hole. The inclined surface B is located at the position inside the inner groove close to the bottom end of the outer hole.

[0013] A sliding groove is opened at one end of the knife lip close to the inner groove. The end of the plugging block away from the inner groove is slidably arranged in the sliding groove and connected to the moving end of the oppositely moving assembly.

[0014] Preferably, the opposite moving component includes a servo motor, a fixing plate, guide bars, racks, a main gear, driven gears, and a reversing gear. The servo motor is fixedly embedded in the inner wall of the side plate. The fixing plate is fixedly connected to the servo motor. The output end of the servo motor is rotatably inserted into the fixing plate. The guide bars are arranged at the top of the fixing plate. The racks are symmetrically and slidably connected to the guide bars. The main gear is sleeved on the output end of the servo motor. The driven gears are symmetrically rotatably arranged on the fixing plate. The bottom ends of the racks are meshed and connected to the driven gears.

[0015] Preferably, the blocking block is fixedly connected to the top end of the rack through a connecting bar.

[0016] Preferably, the driving component includes a micro motor, a driving gear, an idler gear, and a belt. The micro motor is arranged at a position of the cavity shell close to the output hole. The driving gear is connected to the output end of the micro motor. The idler gear is connected to the bottom end of the rotary blowing component.

[0017] Preferably, the rotary blowing component includes a frustum cylinder, a frustum rod, frustum spiral blades, and a hemisphere.

[0018] Preferably, the frustum cylinder, the frustum rod, and the frustum spiral blades are all in a shape that is narrower at the top and wider at the bottom. And the flow path is that the air supply mechanism supplies air to the compression mechanism for compression. The compression mechanism sequentially transmits it to the input pipe, the cavity shell, the output hole, and the frustum cylinder through a telescopic hose, and accelerates and rotates and diffuses and sprays along the spiral axis of the frustum spiral blades. The gas is sprayed and then rotates and spreads away after reaching the contact point.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the present invention, the main stretching oil cylinder drives the moving trolley to move on the frame and the moving crossbeam. The moving trolley drives the stretching jaws to clamp one end of the aluminum profile for straightening. During the straightening process, the surface coating of the aluminum profile breaks and splashes onto the surface and the inner corners. The rotating seat first drives the double-pass air flow mechanism to rotate horizontally by 90 degrees, forming a cross shape with the aluminum profile. Two plugging blocks block the outer holes, and the compressed air supply from the compression mechanism is ejected from the direct injection cavity, forming an outer surface treatment state. Then the rotating seat drives the double-pass air flow mechanism to rotate horizontally by 90 degrees again, forming a linear shape with the aluminum profile. Two plugging blocks block the direct injection cavity, and the compressed air supply from the compression mechanism is ejected from the outer holes. The lifting mechanism drives the knife lip to insert into the groove of the aluminum profile, forming an inner corner treatment state. The aluminum profile straightening device of the present invention can synchronously clean the surface and inner corners of the aluminum profile during the straightening process, avoiding additional secondary cleaning operations after straightening and improving the processing quality and production efficiency of the aluminum profile.

[0021] 2. The present invention also designs the inclined surface A, inclined surface B, mating surface A and mating surface B structures. This mating design enables the plugging blocks to fit better when blocking the outer holes, ensuring the accuracy of gas flow direction control. And being in a mating inclined shape is beneficial to reducing the opposite moving stroke of the opposite moving components, which is particularly important for shortening the stroke in the relatively narrow and cramped installation space of this application. At the same time, when the gas needs to be ejected from the outer holes, it can also make the gas flow more smoothly, further improving the cleaning effect on the inner corners of the aluminum profile.

[0022] 3. The present invention also designs the frustum cylinder, frustum rod and frustum spiral blade structures. When the gas enters the frustum cylinder, under the action of the rotating frustum spiral blade, it accelerates and rotates and diffuses along its spiral axis. This spiral acceleration method makes the gas form a strong rotating air flow. When the gas jets to the contact point on the surface of the aluminum profile, it spreads in a rotating manner. For the water marks on the surface of the aluminum profile, this rotating spreading air flow pattern can produce an excellent cleaning effect. When the strong rotating air flow acts on the water marks, it will quickly push the water marks away. Due to the rotating characteristics of the air flow, the water marks will continuously spread during the pushing process, and their thickness gradually becomes thinner. As the water marks spread and fade, the water can evaporate faster, thus achieving the purpose of removing the water marks. At the same time, this rotating air flow can also increase the contact area with the surface of the aluminum profile, ensuring that the impurities on the surface of the aluminum profile can be more comprehensively removed. When cleaning the inner corners of the aluminum profile, the rotating air flow can enter the gaps and dead corners of the profile more deeply, effectively removing the residual coating debris, water marks and dust, significantly improving the cleaning effect.

[0050] As Figures 1 to 18 shown, a straightening device for aluminum profile processing according to the present invention includes a frame 1, a moving crossbeam 2 is arranged on the frame 1, a main stretching oil cylinder 3 is arranged at one end of the frame 1, a moving trolley 4 is slidably arranged on the frame 1 and the moving crossbeam 2, one end of the moving trolley 4 is connected to the output end of the main stretching oil cylinder 3, a stretching tong head 5 is arranged on the moving trolley 4, a lifting mechanism 6 is arranged at the end of the moving trolley 4 away from the main stretching oil cylinder 3, a bearing plate 7 is arranged at the moving end of the lifting mechanism 6, a compression mechanism 8 is arranged at one end of the bearing plate 7, a rotary seat 10 is arranged at the other end of the bearing plate 7, and a double-pass air flow mechanism 9 is arranged on the rotary seat 10;

[0051] The double-pass air flow mechanism 9 includes a lip body assembly 902 and a plugging block 904. The lip body assembly 902 includes a knife lip 9021, a direct injection cavity 9022, an inner groove 9023, and an outer hole 9024. The knife lips 9021 are symmetrically arranged on the bearing beam assembly 901. The direct injection cavity 9022 is arranged between the two knife lips 9021. The inner groove 9023 is opened on the inner side wall of the knife lip 9021. The outer hole 9024 is opened on the outer side wall of the knife lip 9021. The plugging block 904 is movably inserted into the inner groove 9023.

[0052] When the two plugging blocks 904 block the outer holes 9024, an outer surface treatment state is formed. When the two plugging blocks 904 block the direct injection cavity 9022, an inner corner treatment state is formed.

[0053] In the present invention, the main stretching oil cylinder 3 drives the moving trolley 4 to move on the frame 1 and the moving cross beam 2. The moving trolley 4 drives the stretching clamp head 5 to clamp one end of the aluminum profile for straightening. During the straightening process, the surface coating of the aluminum profile breaks and splashes onto the surface and inner corners. The rotating seat 10 first drives the double-pass air flow mechanism 9 to horizontally rotate 90 degrees to form a cross shape with the aluminum profile. The two plugging blocks 904 block the outer holes 9024, and the compressed air supplied by the compression mechanism 8 is sprayed out from the direct injection cavity 9022 to form an outer surface treatment state. The rotating seat 10 drives the double-pass air flow mechanism 9 to horizontally rotate 90 degrees to form a linear shape with the aluminum profile. The two plugging blocks 904 block the direct injection cavity 9022, and the compressed air supplied by the compression mechanism 8 is sprayed out from the outer holes 9024. The lifting mechanism 6 drives the knife lips 9021 to insert into the groove of the aluminum profile, as Figure 12 shown, to form an inner corner treatment state. The aluminum profile straightening device of the present invention can synchronously clean the surface and inner corners of the aluminum profile during the straightening process, avoiding additional secondary cleaning operations after straightening, and improving the processing quality and production efficiency of the aluminum profile.

[0054] In an embodiment of the present invention, the input end of the double-pass air flow mechanism 9 is connected to the output end of the compression mechanism 8 through a telescopic hose 11. The input end of the compression mechanism 8 is connected to a gas supply mechanism. The compression mechanism 8, the telescopic hose 11, the direct injection cavity 9022, the inner groove 9023, and the outer hole 9024 are communicated.

[0055] In the operation system of the aluminum profile straightening device of the present invention, the double-pass air flow mechanism 9 is connected to the compression mechanism 8 through a telescopic hose 11. The telescopic hose 11 not only ensures the flexible rotation of the double-pass air flow mechanism 9 driven by the rotating seat 10, but also effectively avoids the winding or damage of the gas transmission pipeline caused by the relative movement of the device components, greatly improving the stability and reliability of the device operation. The input end of the compression mechanism 8 is connected to a gas supply mechanism, and its main function is to compress the input gas to ensure that the output gas has sufficient pressure to meet the requirements for cleaning the surface and inner corners of the aluminum profile. The high-pressure gas output by the compression mechanism 8 is transported to the double-pass air flow mechanism 9 through the telescopic hose 11.

[0056] In addition, the compression mechanism 8, the telescopic hose 11, the direct injection cavity 9022, the inner groove 9023 and the outer hole 9024 are interconnected to form a complete gas transmission channel. When treating the outer surface of the aluminum profile, gas starts from the compression mechanism 8, passes through the telescopic hose 11, and is ejected from the direct injection cavity 9022; when treating the inner corner of the aluminum profile, the gas will pass through the compression mechanism 8, the telescopic hose 11, and be ejected from the outer hole 9024 through the inner groove 9023, accurately realizing the cleaning operation under different working conditions.

[0057] In the embodiment of the present invention, the dual-channel air flow mechanism 9 further includes a bearing beam assembly 901, an oppositely moving assembly 903, a driving assembly 905 and a rotary blowing assembly 906. The bearing beam assembly 901 is arranged on the rotating seat 10 and is connected to the telescopic hose 11. The lip body assembly 902 is symmetrically arranged on the bearing beam assembly 901. The oppositely moving assembly 903 is arranged on the bearing beam assembly 901. The blocking block 904 is connected to the moving end of the oppositely moving assembly 903. The driving assembly 905 is arranged on the bearing beam assembly 901. A plurality of rotary blowing assemblies 906 are arranged at the position of the bearing beam assembly 901 between the two knife lips 9021. The output end of the driving assembly 905 is meshed and connected to the rotary blowing assembly 906.

[0058] In the present invention, the bearing beam assembly 901 is installed on the rotating seat 10, and one end of it is connected to the telescopic hose 11, responsible for introducing the gas output by the compression mechanism 8 into the dual-channel air flow mechanism 9. The lip body assembly 902 is symmetrically installed on the bearing beam assembly 901, and the knife lip 9021 can accurately insert into the shaped groove of the aluminum profile, cooperating with the air flow to realize the cleaning of the inner corner.

[0059] The oppositely moving assembly 903 is installed on the bearing beam assembly 901, and its moving end is connected to the blocking block 904. Through the action of the oppositely moving assembly 903, the blocking block 904 can selectively block the direct injection cavity 9022 or the outer hole 9024, thereby switching the gas ejection path to meet the different cleaning requirements of the outer surface and inner corner of the aluminum profile.

[0060] In the embodiment of the present invention, the bearing beam assembly 901 includes an input pipe 9011, side plates 9012, a cavity shell 9013 and output holes 9014. The cavity shell 9013 is arranged on the rotating seat 10, and the side plates 9012 are symmetrically arranged on the cavity shell 9013. One end of the input pipe 9011 is connected to the end of the telescopic hose 11 away from the compression mechanism 8, and the other end of the input pipe 9011 is connected to the side plate 9012 and is communicated with the cavity shell 9013. The output holes 9014 are linearly and equidistantly arranged at the top of the cavity shell 9013. The knife lips 9021 are symmetrically arranged at the top of the cavity shell 9013. The rotary blowing assemblies 906 are arranged at the position of the cavity shell 9013 at the output holes 9014.

[0061] In the present invention, the specific structure and function of the bearing beam assembly 901 are further refined. The cavity shell 9013 is installed on the rotating base 10, and the side plates 9012 are symmetrically arranged on the cavity shell 9013. One end of the input pipe 9011 is connected to the end of the telescopic hose 11 away from the compression mechanism 8, and the other end is connected to the side plate 9012 and communicates with the cavity shell 9013, so that the gas output by the compression mechanism 8 can smoothly enter the cavity shell 9013 through the telescopic hose 11 and the input pipe 9011.

[0062] In an embodiment of the present invention, an inclined surface A9025 and an inclined surface B9026 are provided at one end of the inner side groove 9023 close to the outer side hole 9024. The inclined surface A9025 is located at a position close to the top end of the outer side hole 9024 inside the inner side groove 9023, and the inclined surface B9026 is located at a position close to the bottom end of the outer side hole 9024 inside the inner side groove 9023; these two inclined surfaces can guide the gas to flow more smoothly from the inner side groove 9023 to the outer side hole 9024, optimize the air flow direction and velocity, and improve the cleaning effect on the inner corner of the aluminum profile.

[0063] A sliding groove 9027 is formed at one end of the cutter lip 9021 close to the inner side groove 9023. One end of the blocking block 904 away from the inner side groove 9023 is slidably arranged in the sliding groove 9027 and is connected to the moving end of the opposite moving assembly 903.

[0064] As another embodiment of the present invention, the opposite moving assembly 903 includes a servo motor 9031, a fixing plate 9032, guide bars 9033, a rack 9034, a main gear 9035, a driven gear 9036 and a reversing gear 9037. The servo motor 9031 is fixedly embedded in the inner wall of the side plate 9012, the fixing plate 9032 is fixedly connected to the servo motor 9031, the output end of the servo motor 9031 is rotatably inserted into the fixing plate 9032, the guide bars 9033 are arranged at the top end of the fixing plate 9032, the rack 9034 is symmetrically and slidably connected to the guide bars 9033, the main gear 9035 is sleeved on the output end of the servo motor 9031, the driven gears 9036 are symmetrically rotatably arranged on the fixing plate 9032, the bottom end of the rack 9034 is meshed and connected to the driven gears 9036, one of the driven gears 9036 is meshed and connected to the main gear 9035, the reversing gear 9037 is rotatably arranged on the fixing plate 9032, one end of the reversing gear 9037 is meshed and connected to the main gear 9035, the other end of the reversing gear 9037 is meshed and connected to the driven gear 9036, and one end of the blocking block 904 is fixedly connected to the top end of the rack 9034.

[0065] In the present invention, when the servo motor 9031 is started, the main gear 9035 rotates accordingly. Through meshing with the driven gear 9036 and the reversing gear 9037, it drives the two racks 9034 to slide towards or away from each other on the guide bar 9033, and further enables the plugging block 904 to slide within the chute 9027 of the cutting lip 9021, realizing the selective blockage of the direct injection cavity 9022 or the outer hole 9024, so as to switch the gas ejection path.

[0066] As another embodiment of the present invention, the plugging block 904 is fixedly connected to the top end of the rack 9034 through the connecting bar 9041. An adapting surface A9042 and an adapting surface B9043 are further provided at one end of the plugging block 904 close to the outer hole 9024. The adapting surface A9042 is located at the upper end of the plugging block 904, and the adapting surface B9043 is located at the lower end of the plugging block 904. The adapting surface A9042 is adapted to the inclined surface A9025, and the adapting surface B9043 is adapted to the inclined surface B9026. This adapting design enables the plugging block 904 to fit better when blocking the outer hole 9024, ensuring the accuracy of gas flow control. And being in an adapted inclined shape is beneficial to reducing the opposite movement stroke of the opposite movement assembly 903. Shortening the stroke is particularly important in the relatively narrow and cramped installation space of this application. At the same time, when gas needs to be ejected from the outer hole 9024, it can also make the gas flow more smoothly, further improving the cleaning effect on the inner corner of the aluminum profile.

[0067] As another embodiment of the present invention, the driving assembly 905 includes a micro motor 9051, a driving gear 9052, an idler gear 9053 and a belt 9054. The micro motor 9051 is arranged at a position of the cavity shell 9013 close to the output hole 9014. The driving gear 9052 is connected to the output end of the micro motor 9051. The idler gear 9053 is connected to the bottom end of the rotary blowing assembly 906. The idler gear 9053 is meshed and connected with the driving gear 9052. The belt 9054 is connected to two adjacent idler gears 9053. When the micro motor 9051 is started, the driving gear 9052 rotates, driving the meshed idler gear 9053 to rotate. At the same time, through the transmission of the belt 9054, multiple rotary blowing assemblies 906 rotate synchronously.

[0068] As another embodiment of the present invention, the rotary blowing assembly 906 includes a frustum cylinder 9061, a frustum rod 9062, a frustum spiral blade 9063 and a hemisphere 9064. The frustum cylinder 9061 is fixedly arranged at a position of the cavity shell 9013 directly above the output hole 9014. The frustum rod 9062 is rotatably connected to the inner wall of the frustum cylinder 9061 through the frustum spiral blade 9063. The frustum spiral blade 9063 is fixedly connected to the frustum rod 9062. The hemisphere 9064 is arranged at the bottom end of the frustum rod 9062. One end of the idler gear 9053 far from the driving gear 9052 is fixedly connected to the hemisphere 9064.

[0069] As another embodiment of the present invention, the frustum cylinder 9061, the frustum rod 9062, and the frustum spiral blade 9063 are all in the form of being narrower at the top and wider at the bottom. Moreover, the flow path is that the gas supply mechanism transports gas to the compression mechanism 8 for compression, and the compression mechanism 8 sequentially transmits it to the input pipe 9011, the cavity shell 9013, the output hole 9014, and the frustum cylinder 9061 through the telescopic hose 11, and sprays out in an accelerated rotation and diffusion along the spiral axis of the frustum spiral blade 9063. After the gas is sprayed to the contact point, it spreads out in a rotating manner, as Figure 18 shown.

[0070] The frustum cylinder 9061 of the present invention is fixedly installed on the cavity shell 9013 and is directly above the output hole 9014, providing support for other components and guiding the airflow ejected from the output hole 9014. The frustum rod 9062 realizes a rotational connection with the inner wall of the frustum cylinder 9061 with the help of the frustum spiral blade 9063. The frustum spiral blade 9063 is firmly connected to the frustum rod 9062. When the frustum rod 9062 is driven to rotate by an external force, the frustum spiral blade 9063 rotates accordingly. The hemisphere 9064 is arranged at the bottom end of the frustum rod 9062, and one end of the idler gear 9053 away from the driving gear 9052 is fixedly connected to the hemisphere 9064. When the micro motor 9051 of the driving assembly 905 is started, the driving gear 9052 drives the idler gear 9053 to rotate, and then drives the hemisphere 9064 and the frustum rod 9062 to rotate.

[0071] It should be noted that the frustum cylinder 9061, the frustum rod 9062, and the frustum spiral blade 9063 are all designed in the form of being narrower at the top and wider at the bottom. This unique structural design is of great significance. During the gas flow process, the shape that is narrower at the top and wider at the bottom can gradually compress the gas during circulation, thereby increasing the flow rate and pressure of the gas.

[0072] Its complete gas flow path is as follows: The gas supply mechanism transports gas to the compression mechanism 8 for compression. The compressed high-pressure gas is sequentially transmitted to the input pipe 9011, the cavity shell 9013, the output hole 9014 through the telescopic hose 11, and finally reaches the frustum cylinder 9061. When the gas enters the frustum cylinder 9061, under the action of the rotating frustum spiral blade 9063, it accelerates in rotation and diffuses along its spiral axis. This spiral acceleration method enables the gas to form a strong rotating airflow. When the gas is sprayed to the contact point on the surface of the aluminum profile, it spreads out in a rotating manner, as Figure 18 shown.

[0073] For the water marks on the surface of aluminum profiles, this rotating and pushing air flow pattern can produce excellent cleaning effects. When the strong rotating air flow acts on the water marks, it will quickly push them away. Due to the rotating characteristics of the air flow, the water marks will continuously spread during the pushing process, and their thickness will gradually become thinner. As the water marks spread and fade, the moisture can evaporate faster, thus achieving the purpose of removing the water marks. At the same time, this rotating air flow can also increase the contact area with the surface of the aluminum profile, ensuring that the impurities on the surface of the aluminum profile can be more comprehensively removed. When cleaning the inner corners of the aluminum profile, the rotating air flow can penetrate deeper into the gaps and dead corners of the profile, effectively removing the residual coating debris, water marks and dust, and significantly improving the cleaning effect.

[0074] Working principle: This embodiment provides a method for using a straightening device for aluminum profile processing, including the following steps:

[0075] S1. Straightening operation stage;

[0076] Fix one end of the aluminum profile to the stretching clamp head 5, and start the main stretching oil cylinder 3. The main stretching oil cylinder 3 pushes the moving trolley 4, so that it moves on the frame 1 and the moving crossbeam 2. The moving trolley 4 drives the stretching clamp head 5 to apply a pulling force to the aluminum profile to achieve the straightening operation. However, during the straightening process, the surface coating of the aluminum profile will break due to stress deformation and splash onto the surface and inner corners of the aluminum profile.

[0077] S2. Air flow preparation stage;

[0078] The air supply mechanism outputs gas, and the gas is compressed by the compression mechanism 8 to obtain higher pressure and flow rate. The compressed gas passes through the telescopic hose 11, is transmitted to the input pipe 9011 of the double-pass air flow mechanism 9, enters the cavity shell 9013, and then flows out from the output hole 9014 to provide air source support for the subsequent cleaning work.

[0079] S3. Processing operation stage;

[0080] S3.1. Aluminum profile outer surface cleaning stage;

[0081] When it is necessary to clean the outer surface of the aluminum profile, the rotating seat 10 drives the double-pass air flow mechanism 9 to rotate horizontally by 90 degrees, so that the double-pass air flow mechanism 9 is in a cross shape with the aluminum profile. At this time, the opposing movement component 903 works, the servo motor 9031 drives the main gear 9035 to rotate, and through the reversing gear 9037 and the driven gear 9036, drives the rack 9034 to slide on the guide bar 9033, so that the plugging block 904 blocks the outer hole 9024. The gas can only be ejected from the direct injection cavity 9022 to blow the surface of the aluminum profile and remove the impurities generated by the splashing of the broken coating on the surface.

[0082] S3.2. Aluminum profile inner corner cleaning stage;

[0083] After the outer surface cleaning is completed, the rotating base 10 drives the double-pass air flow mechanism 9 to horizontally rotate 90 degrees, making it in a linear shape with the aluminum profile. The opposing movement component 903 acts again, and the blocking block 904 moves in the reverse direction to block the direct injection cavity 9022. The gas is ejected from the outer hole 9024 through the inner groove 9023. At the same time, the lifting mechanism 6 drives the knife lip 9021 to insert into the aluminum profile groove, and the inclined surfaces A9025 and B9026 of the inner groove 9023 guide the air flow to clean the inner corner of the aluminum profile.

[0084] S4. Rotary blowing to enhance the cleaning effect stage;

[0085] The micro motor 9051 of the driving component 905 starts, driving the driving gear 9052 to rotate. The driving gear 9052 meshes with the idler gear 9053, causing the idler gear 9053 to drive the hemisphere 9064 and the frustum rod 9062 to rotate. The frustum spiral blade 9063 rotates synchronously with the frustum rod 9062, prompting the air flow entering the frustum cylinder 9061 from the output hole 9014 to be ejected along the spiral axis with accelerated rotation and diffusion. This rotating air flow increases the contact area with the surface of the aluminum profile, improves the cleaning effect, pushes the water marks away, spreads and fades them, and thoroughly removes the impurities on the surface and inner corners of the aluminum profile.

[0086] The embodiments disclosed in the present invention are preferred embodiments, but are not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
