Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum profile processing technology, specifically an aluminum profile straightening device. Background Technology
[0002] During the production and processing of aluminum profiles, various factors, such as uneven stress during casting, residual deformation after extrusion molding, and external forces during subsequent processing, inevitably lead to shape deviations such as bending and twisting. This not only affects the appearance quality of the aluminum profiles but, more importantly, adversely impacts their subsequent assembly, use, and overall structural stability. Therefore, straightening aluminum profiles is an indispensable and crucial step in their production and processing, ensuring that they meet the precision requirements for subsequent processing and applications.
[0003] Currently, most common aluminum profile straightening devices employ a single-direction or fixed-mode straightening method to meet basic straightening requirements. However, existing technologies have some limitations. For example, some devices achieve straightening simply by pressing and adjusting up and down or left and right, resulting in poor adaptability to aluminum profiles of different sizes. This leads to frequent clamp changes or structural adjustments when dealing with various aluminum profile specifications, making operation cumbersome and inefficient. Moreover, during the straightening process, uneven distribution of straightening force can easily generate new internal stresses in the aluminum profile, leading to twisting or deformation after straightening, affecting straightening accuracy and quality, and failing to meet the stringent requirements of high-precision aluminum profile production. Furthermore, some existing straightening devices have relatively simple structural designs, lacking multi-dimensional constraint and straightening functions for the aluminum profile. This results in insufficient stability of the aluminum profile during straightening, making it prone to displacement or swaying, further affecting the straightening effect.
[0004] To address the aforementioned issues, this application provides an aluminum profile straightening device. Utility Model Content
[0005] The purpose of this utility model is to provide an aluminum profile straightening device in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] An aluminum profile straightening device includes a processing table, an upper and lower straightening mechanism, and a left and right straightening mechanism, wherein:
[0008] The upper and lower straightening mechanism is installed on the processing table. The upper and lower straightening mechanism consists of a lower straightening component and an upper straightening component. The lower straightening component is used to drive the aluminum profile to move. The height of the upper straightening component is adjustable and, together with the lower straightening component, can straighten the upper and lower sides of the aluminum profile.
[0009] The left and right straightening mechanism is installed on the processing table. The left and right straightening mechanism consists of two side straightening components. The two side straightening components are symmetrically arranged on both sides of the upper and lower straightening mechanism. The distance between the two side straightening components is adjustable and used to straighten the left and right sides of the aluminum profile.
[0010] Furthermore, the lower straightening assembly includes a mounting frame arranged along the length of the processing table and fixed on the processing table. A plurality of lower straightening rollers arranged in an array and located on the same horizontal plane are rotatably mounted on the mounting frame. A connecting wheel is fixedly sleeved on the rotating shaft of the lower straightening roller. An integral connecting belt is sleeved between the connecting wheels on two adjacent lower straightening rollers. The lower straightening assembly also includes a servo motor one arranged below the processing table. A driving wheel is fixedly sleeved on the output end of the servo motor one. A driven wheel is fixedly sleeved on the rotating shaft of one of the lower straightening rollers. An integral transmission belt is sleeved between the driven wheel and the driving wheel.
[0011] Furthermore, the upper straightening assembly includes a device frame movably disposed directly above the lower straightening assembly. Several upper straightening rollers are rotatably mounted on the bottom of the device frame, arranged in an array and located on the same horizontal plane. The several upper straightening rollers are located directly above the several lower straightening rollers and correspond one-to-one. The upper straightening assembly also includes a hydraulic cylinder 1 vertically mounted on the top of the processing table. The output end of the hydraulic cylinder 1 faces downward and is fixed to the top of the device frame.
[0012] Furthermore, at least one vertical guide rod is fixed on the device frame, and the guide rod extends movably through the top of the processing table.
[0013] Furthermore, the side straightening assembly includes a connecting frame arranged along the length of the mounting frame. Two fixed frames are arranged vertically on the side of the connecting frame near the upper and lower straightening mechanism. Several straightening wheels are rotatably mounted on each of the two fixed frames in an array. The several straightening wheels on the two fixed frames correspond one-to-one. The bottom side of the lower straightening wheel is higher than the top side of the lower straightening roller. The side straightening assembly also includes a hydraulic cylinder II horizontally mounted on the processing table. The output end of the hydraulic cylinder II is fixed to the connecting frame.
[0014] Furthermore, the lower fixing bracket is fixed to the connecting bracket, and the upper fixing bracket is vertically slidably mounted on the connecting bracket. A second servo motor is mounted on the connecting bracket, and the output end of the second servo motor is upward and fixed with a vertical threaded rod. The upper connecting bracket is threaded onto the threaded rod.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In this solution, the height of the upper straightening component is adjustable, and the distance between the two side straightening components in the left and right straightening mechanisms is variable. This design enables the straightening device to adapt to various rectangular aluminum profiles of different sizes without the need for frequent fixture changes or complex structural adjustments to the equipment. This significantly improves the versatility of the device, saves production preparation time and costs, and is especially suitable for processing aluminum profiles of various specifications.
[0017] This solution, through the coordinated operation of the upper and lower straightening mechanisms and the left and right straightening mechanisms, can simultaneously straighten the four sides of the aluminum profile. The pressure of each straightening component can be precisely controlled to ensure the uniform distribution of the straightening force. This avoids the situation where the aluminum profile is twisted or deformed due to the generation of new internal stress caused by uneven straightening force, effectively ensuring the straightness and dimensional accuracy of the aluminum profile after straightening, and meeting the requirements of high-quality aluminum profile production.
[0018] In this design, the lower straightening component has several lower straightening rollers arranged in an array and located on the same horizontal plane, and the upper straightening component also has upper straightening rollers arranged in an array. The two components work together to provide stable support and straightening for the upper and lower sides of the aluminum profile. The two side straightening components of the left and right straightening mechanisms are symmetrically arranged on both sides of the upper and lower straightening mechanisms, and each side straightening component has multiple straightening wheels arranged vertically. This provides multi-point constraint and correction for the aluminum profile from both sides, greatly enhancing the stability of the aluminum profile during the straightening process, preventing displacement or shaking, and ensuring the reliability of the straightening effect.
[0019] In this design, both the upper and lower straightening mechanisms and the left and right straightening mechanisms are installed on the processing table. The overall layout is compact and reasonable, and the components coordinate with each other without interfering with each other, forming an efficient and orderly straightening operation system. At the same time, the device frame is equipped with guide rods, and the connecting frame is equipped with stabilizing rods and other structures that move through the processing table, which further enhances the stability and reliability of the device during operation and extends the service life of the equipment.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0027] This application provides an aluminum profile straightening device, mainly to address the shortcomings of existing devices that rely solely on simple up-and-down or left-and-right clamping and adjustment for straightening, resulting in poor adaptability to aluminum profiles of different sizes. This leads to frequent fixture changes or equipment adjustments when dealing with various profile specifications, making operation cumbersome and inefficient. Furthermore, during the straightening process, uneven force distribution can easily generate new internal stresses in the aluminum profile, causing distortion or deformation after straightening, affecting straightening accuracy and quality, and failing to meet the stringent requirements of high-precision aluminum profile production. In addition, some existing straightening devices have relatively simple structural designs, lacking multi-dimensional constraint and straightening functions for the aluminum profile. This results in insufficient stability of the aluminum profile during straightening, making it prone to displacement or swaying, further affecting the straightening effect. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:
[0028] An aluminum profile straightening device mainly includes a processing table 1, an upper and lower straightening mechanism 2, and a left and right straightening mechanism 3, wherein:
[0029] The upper and lower straightening mechanism 2 is installed on the processing table 1. The upper and lower straightening mechanism 2 consists of a lower straightening component 21 and an upper straightening component 22. The lower straightening component 21 is used to drive the aluminum profile to move. The height of the upper straightening component 22 is adjustable and, together with the lower straightening component 21, can straighten the upper and lower sides of the aluminum profile.
[0030] The left and right straightening mechanism 3 is installed on the processing table 1. The left and right straightening mechanism 3 consists of two side straightening components 31. The two side straightening components 31 are symmetrically arranged on both sides of the upper and lower straightening mechanism 2. The distance between the two side straightening components 31 is adjustable and used to straighten the left and right sides of the aluminum profile.
[0031] In actual use, the aluminum profile to be straightened is first placed on the lower straightening component 21 of the processing table 1. At this time, the lower straightening component 21 drives the aluminum profile to move along the length direction of the processing table 1. The upper straightening component 22 and the lower straightening component 21 straighten the upper and lower sides of the aluminum profile, while the left and right straightening mechanism 3 straightens the left and right sides of the aluminum profile.
[0032] The upper and lower straightening mechanism 2 and the left and right straightening mechanism 3 of this device work together to form a complete straightening system, which enhances the stability of the aluminum profile during the straightening process, prevents it from shifting or shaking, and ensures the reliability of the straightening effect.
[0033] For details, please refer to Figure 2 , Figure 3 and Figure 4 The lower straightening assembly 21 includes a mounting frame 211 that is set along the length of the processing table 1 and fixed on the processing table 1. Several lower straightening rollers 212 that are arranged in an array and located on the same horizontal plane are rotatably mounted on the mounting frame 211. These lower straightening rollers 212 can effectively support the bottom of the aluminum profile and drive the aluminum profile to move during rotation. A connecting wheel 213 is fixedly sleeved on the rotating shaft of the lower straightening roller 212. An integrated connecting belt 214 is sleeved between the connecting wheels 213 on two adjacent lower straightening rollers 212, forming an interconnected and synchronously rotating whole, ensuring the smoothness of the aluminum profile movement process. The lower straightening assembly 21 also includes a servo motor 215 set below the processing table 1. A drive wheel 216 is fixedly sleeved on the output end of the servo motor 215. A driven wheel 217 is fixedly sleeved on the rotating shaft of one of the lower straightening rollers 212. An integrated transmission belt 218 is sleeved between the driven wheel 217 and the drive wheel 216.
[0034] When straightening is required, servo motor 215 starts, and drive wheel 216 rotates under the drive of servo motor 215. Driven by transmission belt 218, it drives driven wheel 217 to rotate, which in turn causes the lower straightening roller 212 to rotate. Due to the transmission effect of linkage belt 214, the adjacent lower straightening rollers 212 also rotate synchronously, thereby realizing the coordinated operation of the entire lower straightening assembly 21, driving the aluminum profile to move stably and efficiently to the straightening position.
[0035] This design gives the lower straightening assembly 21 excellent transmission performance and stability, enabling precise control of the aluminum profile's movement speed and position, providing a solid foundation for subsequent straightening operations. The close cooperation between its components not only improves the device's operating efficiency but also enhances its reliability and durability.
[0036] Furthermore, in this aluminum profile straightening device, the upper straightening component 22 is designed to work closely with the lower straightening component 21 to achieve precise straightening of the upper and lower sides of the aluminum profile. The upper straightening component 22 includes a device frame 221 that is movably set directly above the lower straightening component 21. Several upper straightening rollers 222 are rotatably mounted on the bottom of the device frame 221 and are arranged in an array and located on the same horizontal plane. The several upper straightening rollers 222 are located directly above the several lower straightening rollers 212 and correspond one to one. The upper straightening component 22 also includes a hydraulic cylinder 223 that is vertically installed on the top of the processing table 1. The output end of the hydraulic cylinder 223 is downward and fixed to the top of the device frame 221.
[0037] When straightening aluminum profiles of different heights is required, the hydraulic cylinder 223 is activated, and the output end extends and retracts, driving the device frame 221 to move vertically. This causes the upper straightening roller 222 to move closer to or further away from the lower straightening roller 212 to accommodate the height of the aluminum profile. During the straightening process, the aluminum profile is placed on the lower straightening roller 212, and the upper straightening roller 222 applies downward pressure to the aluminum profile under the action of the hydraulic cylinder 223. Together with the lower straightening roller 212, the upper and lower sides of the aluminum profile are straightened to ensure the straightness and dimensional accuracy of the aluminum profile in the vertical direction.
[0038] In the upper straightening assembly 22 of this aluminum profile straightening device, the design details of the device frame 221 further optimize its function and stability. At least one vertical guide rod 224 is fixed on the device frame 221. The guide rod 224 moves through the top of the processing table 1. During the vertical movement of the device frame 221, the guide rod 224 plays a key guiding role, ensuring that the movement trajectory of the device frame 221 always remains vertical, and avoiding the problem of uneven force applied to the aluminum profile by the upper straightening roller 222 due to the offset or shaking of the device frame 221.
[0039] In this embodiment, the side straightening component 31 is designed to closely cooperate with the upper and lower straightening mechanisms 2 in the aluminum profile straightening device, achieving efficient straightening of the left and right sides of the aluminum profile. Please refer to [link / reference]. Figure 2 , Figure 3 and Figure 5 The side straightening assembly 31 includes a connecting frame 311 arranged along the length of the mounting frame 211. Two vertically distributed fixed frames 312 are arranged on the side of the connecting frame 311 near the upper and lower straightening mechanisms 2. Several straightening wheels 313 arranged in an array are rotatably mounted on each of the two fixed frames 312. The straightening wheels 313 on the two fixed frames 312 correspond one-to-one, with the bottom side of the lower straightening wheel 313 higher than the top side of the lower straightening roller 212. This design allows the straightening wheels 313 to effectively constrain and straighten the left and right sides of the aluminum profile without affecting the normal operation of the lower straightening roller 212. When the aluminum profile moves to the exact center position of the left and right straightening mechanisms 3 under the action of the upper and lower straightening mechanisms 2, the straightening of the side straightening assembly 31 is achieved. The straightening wheels 313 contact the left and right sides of the aluminum profile to straighten the left and right sides of the aluminum profile. The straightening wheels 313 on the two fixed frames 312 work together to ensure the straightening effect on the left and right sides of the aluminum profile. The side straightening component 31 also includes a hydraulic cylinder 314 horizontally mounted on the processing table 1. The output end of the hydraulic cylinder 314 is fixed to the connecting frame 311. By extending and retracting the hydraulic cylinder 314, the distance between the two side straightening components 31 can be adjusted to adapt to aluminum profiles of different widths. This adjustment method is flexible and convenient, and can quickly respond to the straightening needs of aluminum profiles of different specifications, improving the versatility and operating efficiency of the device. It should be noted that in this embodiment, an external oil supply component is also included to supply oil to the hydraulic cylinder 223 and the hydraulic cylinder 314.
[0040] Furthermore, the lower fixing bracket 312 is fixed to the connecting bracket 311, and the upper fixing bracket 312 is vertically slidably mounted on the connecting bracket 311. This design allows the upper fixing bracket 312 to be adjusted in the vertical direction to accommodate aluminum profiles of different heights and sizes, further enhancing the flexibility and versatility of the device. A second servo motor 315 is mounted on the connecting bracket 311. The output end of the second servo motor 315 faces upward and is fixed with a vertical threaded rod 316. The upper connecting bracket 311 is threaded onto the threaded rod 316. When it is necessary to adjust the height of the upper fixing bracket 312, the second servo motor 315 is started, driving the threaded rod 316 to rotate. Due to the threaded connection, the upper fixing bracket 312 will move in the vertical direction, thereby changing the distance between it and the lower fixing bracket 312.
[0041] This height adjustment mechanism plays a crucial role in the straightening process. When the aluminum profile has different heights, the rotation of the threaded rod 316 is precisely controlled by the servo motor 315, which allows the distance between the straightening wheel 313 on the upper fixed frame 312 and the straightening wheel 313 on the lower frame to be accurately adjusted. This ensures that the straightening wheel 313 can closely fit the left and right sides of the aluminum profile, achieving precise straightening. This design not only improves the straightening accuracy but also ensures the stability of the aluminum profile in the left and right directions, preventing it from shaking or shifting during the straightening process, and further improving the straightening quality.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
