Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing, and more specifically to a straightening device used 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 widespread application of aluminum profiles in industries such as construction, automobiles, and aerospace, the market has increasingly stringent requirements on the quality and appearance of aluminum profiles.

[0003] At present, the existing aluminum profile straightening devices have exposed many problems in actual use, which seriously restricts the quality and efficiency of aluminum profile processing. First, during the straightening process, the aluminum profile will deform, which can easily cause the surface coating to crack and break. This not only affects the appearance quality of the aluminum profile and reduces the market competitiveness of the product, but also requires additional secondary cleaning operations after straightening, which greatly increases the processing cost and time cost.

[0004] Secondly, in the processing technology of aluminum profiles before straightening, they usually need to be passed through water or reagents, which will inevitably leave watermarks on the surface of the aluminum profiles and in the grooves. Traditional watermark and dust treatment methods have obvious limitations. On the one hand, it is impossible to effectively deal with the dust and watermarks in the dead corners of the aluminum profile grooves. These residual substances will affect the subsequent performance of the aluminum profiles. For example, when used in the construction field, it may cause the corrosion resistance of the profiles to decrease. On the other hand, the existing watermark treatment methods are less effective and cannot meet the increasingly high quality standards. For example, in the manufacture of automotive parts with extremely high requirements for surface quality, residual watermarks will seriously affect the aesthetics and overall quality of the product. In summary, the existing aluminum profile straightening devices and related processing 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

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention drives the movable trolley to move on the frame and the movable crossbeam through the main stretching oil cylinder, and the movable trolley drives the stretching clamp head 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 angle. The rotating seat first drives the double-pass airflow mechanism to rotate horizontally 90 degrees to form a cross shape with the aluminum profile, and the two blocking blocks block the outer holes. The air supply of the compression mechanism is ejected from the direct injection chamber to form a surface treatment state. The rotating seat drives the double-pass airflow mechanism to rotate horizontally 90 degrees to form a linear shape with the aluminum profile. The two blocking blocks block the direct injection chamber, and the air supply of the compression mechanism is ejected from the outer holes. The lifting mechanism drives the knife lip to insert into the aluminum profile groove to form an inner angle treatment state. The aluminum profile straightening device of the present invention can simultaneously clean the surface and inner angle of the aluminum profile during the straightening process, thereby avoiding additional secondary cleaning operations after the straightening is completed, and improving the processing quality and production efficiency of the aluminum profile.

[0017] 2. The present invention also designs the structure of inclined surface A, inclined surface B, matching surface A and matching surface B. This matching design enables the blocking block to fit better when blocking the outer hole, thereby ensuring the accuracy of gas flow control. The matching inclined shape is beneficial to reducing the opposite moving stroke of the opposite moving components. Shortening the stroke is particularly important in the relatively narrow and cramped installation space of the present application. At the same time, when the gas needs to be ejected from the outer hole, the gas flow can be smoother, further improving the cleaning effect of the inner corners of the aluminum profile.

[0018] 3. The present invention also designs a truncated cone cylinder, a truncated cone rod and a truncated cone spiral blade structure. When the gas enters the truncated cone cylinder, it is accelerated to rotate and diffuse along its spiral axis under the action of the rotating truncated cone spiral blade. This spiral acceleration method allows 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 is in a rotating and pushing shape. For the watermark on the surface of the aluminum profile, this rotating and pushing airflow pattern can produce an excellent cleaning effect. When the strong rotating airflow acts on the watermark, it will quickly push the watermark away. Due to the rotational characteristics of the airflow, the watermark will continue to spread during the process of being pushed away, and its thickness will gradually become thinner. As the watermark diffuses and fades, the water can evaporate faster, thereby achieving the purpose of removing the watermark. At the same time, this rotating airflow can also increase the contact area with the surface of the aluminum profile, ensuring that impurities on the surface of the aluminum profile can be more comprehensively removed. When cleaning the inner corners of the aluminum profile, the rotating airflow can enter the gaps and dead corners of the profile more deeply, effectively removing residual coating debris, watermarks and dust, and significantly improving the cleaning effect.

DETAILED DESCRIPTION

[0021] like Figures 1 to 18 As shown, the present invention relates to a straightening device for aluminum profile processing, comprising 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 clamp 5 is arranged on the moving trolley 4, a lifting mechanism 6 is arranged at one 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 rotating seat 10 is arranged at the other end of the bearing plate 7, and a double-pass airflow mechanism 9 is arranged on the rotating seat 10; The double-pass airflow mechanism 9 includes a lip assembly 902 and a blocking block 904. The lip 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 support beam assembly 901. The direct injection cavity 9022 is arranged between the two knife lips 9021. The inner groove 9023 is arranged on the inner wall of the knife lip 9021. The outer hole 9024 is arranged on the outer wall of the knife lip 9021. The blocking block 904 is movably inserted in the inner groove 9023. When the two blocking blocks 904 block the outer hole 9024, an outer surface processing state is formed, and when the two blocking blocks 904 block the direct injection cavity 9022, an inner corner processing state is formed.

[0022] The present invention drives the moving trolley 4 to move on the frame 1 and the moving crossbeam 2 through the main stretching cylinder 3. The moving trolley 4 drives the stretching clamp 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 the inner corner. The rotating seat 10 first drives the double-pass airflow mechanism 9 to rotate horizontally 90 degrees to form a cross shape with the aluminum profile. The two blocking blocks 904 block the outer holes 9024. The air supply of the compression mechanism 8 is ejected from the direct injection cavity 9022 to form a surface treatment state. The rotating seat 10 drives the double-pass airflow mechanism 9 to rotate horizontally 90 degrees to form a linear shape with the aluminum profile. The two blocking blocks 904 block the direct injection cavity 9022. The air supply of the compression mechanism 8 is ejected from the outer holes 9024. The lifting mechanism 6 drives the knife lip 9021 to insert into the aluminum profile groove. Fig.12 As shown, an inner corner processing state is formed. The aluminum profile straightening device of the present invention can simultaneously clean the surface and inner corner of the aluminum profile during the straightening process, avoiding additional secondary cleaning operations after the straightening is completed, and improving the processing quality and production efficiency of the aluminum profile.

[0023] In an embodiment of the present invention, the input end of the double-way airflow mechanism 9 is connected to the output end of the compression mechanism 8 through the telescopic hose 11, the input end of the compression mechanism 8 is connected to the air supply mechanism, and the compression mechanism 8, the telescopic hose 11, the direct injection chamber 9022, the inner groove 9023 and the outer hole 9024 are connected.

[0024] In the aluminum profile straightening device operating system of the present invention, the double-way airflow mechanism 9 is connected to the compression mechanism 8 by a telescopic hose 11. The telescopic hose 11 not only ensures that the double-way airflow mechanism 9 can rotate flexibly under the drive of the rotating seat 10, but also effectively avoids the entanglement or damage of the gas transmission pipeline caused by the relative movement of the device components, which greatly improves the stability and reliability of the device operation. The input end of the compression mechanism 8 is connected to the 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-way airflow mechanism 9 through the telescopic hose 11.

[0025] In addition, the compression mechanism 8, the telescopic hose 11, the direct injection chamber 9022, the inner groove 9023 and the outer hole 9024 are interconnected to form a complete gas transmission channel. When processing the surface of the aluminum profile, the gas starts from the compression mechanism 8 and is ejected through the telescopic hose 11 and the direct injection chamber 9022; when processing the inner corner of the aluminum profile, the gas passes through the compression mechanism 8 and the telescopic hose 11 and is ejected from the outer hole 9024 through the inner groove 9023, accurately achieving cleaning operations under different working conditions.

[0026] In an embodiment of the present invention, the dual-channel airflow mechanism 9 also includes a support beam assembly 901, a counter-moving assembly 903, a driving assembly 905 and a rotary blowing assembly 906. The support beam assembly 901 is arranged on the rotating seat 10 and is connected to the telescopic hose 11. The lip assembly 902 is symmetrically arranged on the support beam assembly 901. The counter-moving assembly 903 is arranged on the support beam assembly 901. The blocking block 904 is connected to the moving end of the counter-moving assembly 903. The driving assembly 905 is arranged on the support beam assembly 901. A plurality of rotary blowing assemblies 906 are arranged on the support beam assembly 901 at a position between two blade lips 9021. The output end of the driving assembly 905 is meshedly connected to the rotary blowing assembly 906.

[0027] In the present invention, the support beam assembly 901 is installed on the rotating seat 10, one end of which is connected to the telescopic hose 11, which is responsible for introducing the gas output by the compression mechanism 8 into the double-pass airflow mechanism 9. The lip body assembly 902 is symmetrically installed on the support beam assembly 901, and the knife lip 9021 can be accurately inserted into the groove of the aluminum profile to achieve cleaning of the inner corner with the airflow.

[0028] The opposite moving assembly 903 is installed on the supporting beam assembly 901, and its moving end is connected to the blocking block 904. Through the action of the opposite 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.

[0029] In an embodiment of the present invention, the support beam assembly 901 includes an input pipe 9011, a side plate 9012, a cavity shell 9013 and an output hole 9014. The cavity shell 9013 is arranged on the rotating seat 10, and the side plate 9012 is symmetrically arranged on the cavity shell 9013.

The output hole 9014 is linearly and evenly spaced at the top of the cavity shell 9013, the knife lip 9021 is symmetrically arranged at the top of the cavity shell 9013, and the rotary blowing assembly 906 is arranged at the top of the cavity shell 9013 at the position of the output hole 9014.

[0030] The specific structure and function of the support beam assembly 901 in the present invention are further refined. The chamber shell 9013 is installed on the rotating seat 10, and the side plate 9012 is symmetrically arranged on the chamber 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 communicated with the chamber shell 9013, so that the gas output by the compression mechanism 8 can smoothly enter the chamber shell 9013 through the telescopic hose 11 and the input pipe 9011.

[0031] In an embodiment of the present invention, an inclined surface A9025 and an inclined surface B9026 are provided at one end of the inner groove 9023 close to the outer hole 9024, the inclined surface A9025 is located inside the inner groove 9023 close to the top of the outer hole 9024, and the inclined surface B9026 is located inside the inner groove 9023 close to the bottom of the outer hole 9024; these two inclined surfaces can guide the gas to flow more smoothly from the inner groove 9023 to the outer hole 9024, optimize the airflow direction and flow rate, and improve the cleaning effect of the inner corners of the aluminum profile.

[0032] A sliding groove 9027 is formed at one end of the blade lip 9021 close to the inner groove 9023 , and the blocking block 904 is slidably disposed in the sliding groove 9027 at one end away from the inner groove 9023 and connected to the moving end of the opposite moving component 903 .

[0033] As another embodiment of the present invention, the opposite moving assembly 903 includes a servo motor 9031, a fixed plate 9032, a guide bar 9033, a rack 9034, a main gear 9035, a driven gear 9036 and a reversing gear 9037.

[0034] In the present invention, when the servo motor 9031 is started, the main gear 9035 rotates accordingly, and through the engagement with the driven gear 9036 and the reversing gear 9037, the two racks 9034 are driven to slide in opposite or reverse directions on the guide bar 9033, so that the blocking block 904 slides in the slide groove 9027 of the blade lip 9021, thereby realizing selective blocking of the direct injection cavity 9022 or the outer hole 9024 to switch the gas ejection path.

[0035] As another embodiment of the present invention, the blocking block 904 is fixedly connected to the top of the rack 9034 through a connecting strip 9041. The blocking block 904 is also provided with an adapting surface A9042 and an adapting surface B9043 at one end close to the outer hole 9024. The adapting surface A9042 is located at the upper end of the blocking block 904, and the adapting surface B9043 is located at the lower end of the blocking block 904. The adapting surface A9042 and the inclined surface A9025 are mutually adapted, and the adapting surface B9043 and the inclined surface B9026 are mutually adapted. This adapting design enables the blocking block 904 to fit better when blocking the outer hole 9024, ensuring the accuracy of the gas flow control, and the adapting inclination is conducive to reducing the opposite movement stroke of the opposite moving component 903. It is particularly important to shorten 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 hole 9024, it can also make the gas flow smoother, further improving the cleaning effect of the inner corner of the aluminum profile.

[0036] As another embodiment of the present invention, the driving assembly 905 includes a micro motor 9051, a driving gear 9052, an idle gear 9053 and a belt 9054. The micro motor 9051 is arranged at a position near the output hole 9014 of the cavity shell 9013. The driving gear 9052 is connected to the output end of the micro motor 9051. The idle gear 9053 is connected to the bottom end of the spinning assembly 906. The idle gear 9053 is meshed with the driving gear 9052. The belt 9054 is connected to two adjacent idle gears 9053. When the micro motor 9051 is started, the driving gear 9052 rotates, driving the idle gear 9053 meshed with it to rotate. At the same time, through the transmission of the belt 9054, multiple spinning assemblies 906 rotate synchronously.

[0037] As another embodiment of the present invention, the rotary blowing assembly 906 includes a conical cylinder 9061, a conical rod 9062, a conical spiral blade 9063 and a hemisphere 9064. The conical cylinder 9061 is fixedly arranged on the chamber shell 9013 at a position directly above the output hole 9014. The conical rod 9062 is rotatably connected to the inner wall of the conical cylinder 9061 through the conical spiral blade 9063. The conical spiral blade 9063 is fixedly connected to the conical rod 9062. The hemisphere 9064 is arranged at the bottom end of the conical rod 9062. The idle gear 9053 is fixedly connected to the hemisphere 9064 at one end away from the driving gear 9052.

[0038] As another embodiment of the present invention, the truncated cone cylinder 9061, the truncated cone rod 9062 and the truncated cone spiral blade 9063 are all narrow at the top and wide at the bottom, and the flow path is that the air supply mechanism transmits air to the compression mechanism 8 for compression, and the compression mechanism 8 transmits air to the input pipe 9011, the chamber shell 9013, the output hole 9014 and the truncated cone cylinder 9061 in sequence through the telescopic hose 11, and the gas is accelerated along the spiral axis of the truncated cone spiral blade 9063 to rotate and diffuse and spray out. After the gas is sprayed to the contact point, it is in a rotating push-away shape, such as Fig.18 shown.

[0039] The truncated cone cylinder 9061 of the present invention is fixedly mounted on the chamber shell 9013 and is located just above the output hole 9014, providing support for other components and guiding the airflow ejected from the output hole 9014. The truncated cone rod 9062 is connected to the inner wall of the truncated cone cylinder 9061 by means of the truncated cone spiral blade 9063. The truncated cone spiral blade 9063 is firmly connected to the truncated cone rod 9062. When the truncated cone rod 9062 is driven to rotate by an external force, the truncated cone spiral blade 9063 rotates accordingly. The hemisphere 9064 is arranged at the bottom end of the truncated cone rod 9062, and the end of the idle 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 idle gear 9053 to rotate, thereby driving the hemisphere 9064 and the truncated cone rod 9062 to rotate.

[0040] It is worth noting that the truncated cone cylinder 9061, the truncated cone rod 9062 and the truncated cone spiral blade 9063 are all designed to be narrow at the top and wide at the bottom. This unique structural design is of great significance. During the gas flow process, the narrow at the top and wide at the bottom shape can gradually compress the gas during circulation, thereby increasing the flow rate and pressure of the gas.

[0041] The complete gas flow path is as follows: the gas supply mechanism delivers the gas to the compression mechanism 8 for compression, and 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 truncated cone cylinder 9061. After the gas enters the truncated cone cylinder 9061, it is accelerated and diffused along its spiral axis under the action of the rotating truncated cone spiral blades 9063. This spiral acceleration method makes the gas form a strong rotating airflow. When the gas is sprayed to the contact point on the surface of the aluminum profile, it is in a rotating push-away shape, such as Fig.18 shown.

[0042] For watermarks on the surface of aluminum profiles, this rotating and pushing airflow pattern can produce an excellent cleaning effect. When the strong rotating airflow acts on the watermark, it will quickly push the watermark away. Due to the rotating characteristics of the airflow, the watermark will continue to spread in the process of being pushed away, and its thickness will gradually become thinner. As the watermark spreads and fades, the water can evaporate faster, thereby achieving the purpose of removing the watermark. At the same time, this rotating airflow can also increase the contact area with the surface of the aluminum profile, ensuring that impurities on the surface of the aluminum profile can be more comprehensively removed. When cleaning the inner corners of the aluminum profile, the rotating airflow can penetrate deeper into the gaps and dead corners of the profile, effectively removing residual coating debris, watermarks and dust, and significantly improving the cleaning effect.

[0043] Working principle: This embodiment provides a method for using a straightening device for aluminum profile processing, comprising the following steps: S1, straightening operation stage; Fix one end of the aluminum profile to the stretching clamp 5 and start the main stretching cylinder 3. The main stretching cylinder 3 pushes the moving trolley 4 to move on the frame 1 and the moving beam 2. The moving trolley 4 drives the stretching clamp 5 to apply tension 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 deformation under stress and splash onto the surface and inner corners of the aluminum profile.

[0044] S2, airflow preparation stage; The gas supply mechanism outputs gas, which is compressed by the compression mechanism 8 to obtain a higher pressure and flow rate. The compressed gas is transmitted to the input pipe 9011 of the double-pass airflow mechanism 9 through the telescopic hose 11, enters the cavity shell 9013, and then flows out from the output hole 9014 to provide gas source support for subsequent cleaning work.

[0045] S3, processing operation stage; S3.1, Aluminum profile surface cleaning stage; When it is necessary to clean the surface of the aluminum profile, the rotating seat 10 drives the double-pass airflow mechanism 9 to rotate horizontally by 90 degrees, so that the double-pass airflow mechanism 9 and the aluminum profile are in a cross shape. At this time, the opposite moving component 903 works, and the servo motor 9031 drives the main gear 9035 to rotate, and drives the rack 9034 to slide on the guide bar 9033 through the reversing gear 9037 and the driven gear 9036, so that the blocking block 904 blocks the outer hole 9024. The gas can only be sprayed out from the direct injection cavity 9022 to purge the surface of the aluminum profile and remove impurities generated by the coating fracture and splashing on the surface.

[0046] S3.2, aluminum profile inner corner cleaning stage; After the surface cleaning is completed, the rotating seat 10 drives the double-pass airflow mechanism 9 to rotate horizontally by 90 degrees so that it is in line with the aluminum profile. The opposite moving assembly 903 moves again, and the blocking block 904 moves in the opposite 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 surface A9025 and the inclined surface B9026 of the inner groove 9023 guide the airflow to clean the inner corner of the aluminum profile.

[0047] S4, the stage of enhanced cleaning effect by rotary blowing; The micro motor 9051 of the driving assembly 905 is started, driving the driving gear 9052 to rotate. The driving gear 9052 is meshed with the idle gear 9053, so that the idle gear 9053 drives the hemisphere 9064 and the truncated cone rod 9062 to rotate. The truncated cone spiral blade 9063 rotates synchronously with the truncated cone rod 9062, prompting the airflow entering the truncated cone cylinder 9061 from the output hole 9014 to accelerate and rotate and diffuse along the spiral axis to spray out. This rotating airflow increases the contact area with the surface of the aluminum profile, improves the cleaning effect, pushes away the watermark, diffuses and fades it, and completely removes impurities on the surface and inner corners of the aluminum profile.

A person skilled 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 deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
