Technical Field

[0001] This utility model relates to the field of door and window profile processing, specifically a door and window straightening device. Background Technology

[0002] Aluminum-plastic composite doors and windows are actually a general term for modern door and window products. As the name suggests, they can be understood as aluminum alloy doors and windows and U-PVC plastic steel doors and windows, or aluminum-plastic composite doors and windows, such as thermally broken aluminum doors and windows, aluminum-clad wood doors and windows, and other high-end energy-saving products. When processing and manufacturing aluminum-plastic doors and windows, the profiles of the aluminum-plastic door and window components need to be straightened before use.

[0003] Existing door and window profile straightening equipment has various samples, but the cross-sectional dimensions of the profiles also vary. Therefore, when straightening profiles of different sizes and specifications, more time is required for adjustment, resulting in low straightening efficiency. Secondly, after straightening the bent parts of aluminum profiles, there may be residual stress, which may lead to secondary deformation and a decline in straightening quality. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 In this embodiment of the utility model, a door and window straightening device includes a conveyor 1. The conveyor 1 includes two symmetrically distributed fixed seats 101. Multiple equidistant conveying rollers 102 are rotatably connected between the two fixed seats 101. Two motors 103 are installed on the outside of the fixed seats 101, which are used to drive the two conveying rollers 102 at the outer end respectively.

[0023] The straightening mechanism includes a second straightening component 6 located above the conveyor 1, and two sets of first straightening components 5 symmetrically distributed on both sides of the conveyor 1 in the conveying direction, which are used to cooperate with the conveyor 1 to press and straighten the four end faces of the profile.

[0024] Two side protective plates 2 are fixedly connected to the top of two fixed bases 101, and a top plate 3 is installed between the top of the two side protective plates 2 to form a U-shaped shell.

[0025] Heating component 4 is installed at the bottom of conveyor 1 to transfer heat to the inner cavity of the shell formed by the side protective plate 2 and the top plate 3, so as to reduce the deformation resistance of the door and window profiles.

[0026] The first straightening assembly 5 includes a plurality of first supports 501 equidistantly arranged between two adjacent conveying rollers 102. The first supports 501 have a U-shaped structure, and the inner side of the first support 501 is rotatably connected to the first pressure roller 502. The outer wall of the side guard plate 2 is equipped with a plurality of first hydraulic cylinders 503 equidistantly arranged. The output ends of the plurality of first hydraulic cylinders 503 are all movably penetrating through the outer wall of the side guard plate 2, and the output ends of the plurality of first hydraulic cylinders 503 are respectively fixedly connected to the middle of the outer side end of the corresponding plurality of first supports 501.

[0027] The second straightening assembly 6 includes multiple second supports 601 arranged equidistantly above multiple conveying rollers 102. The second supports 601 have a U-shaped structure. The inner side of the second supports 601 is rotatably connected to the second pressure rollers 602. Multiple second hydraulic cylinders 603 are installed on the top of the top plate 3. The output ends of the multiple second hydraulic cylinders 603 are all movable through the outer wall of the top plate 3, and the output ends of the multiple second hydraulic cylinders 603 are respectively fixedly connected to the middle of the outer side of the corresponding multiple second supports 601.

[0028] The inner walls of the two side protective plates 2 are provided with sliding grooves for the outer side end of the second bracket 601 to slide into.

[0029] The heating component 4 includes a housing 401, which is a rectangular housing structure with an opening at the top. Multiple heating rods 402 arranged at equal intervals are installed inside the housing 401, and a fan 403 is installed at the bottom of the housing 401.

[0030] In this embodiment: the straightening mechanism and the conveying roller 102 on the conveyor 1 cooperate to form a rectangular diameter roller straightening structure, which can be used for straightening various rectangular profiles of different sizes and specifications, greatly improving the versatility of use; secondly, by setting a heating component 4 inside the conveyor 1 to heat the shell cavity where the side guard plate 2 and the top plate 3 are spliced, the deformation resistance of the aluminum profile can be reduced, which is beneficial to the straightening operation of the aluminum profile.

[0031] Specifically, this solution uses a straightening mechanism to straighten rectangular door and window profiles. The door and window profiles are put into the conveyor 1 from one end. The conveyor roller 102 at the outer end is driven by the motor 103 to move the door and window profiles. During the movement, the upper surface of the door and window profiles contacts the second pressure roller 602 in the second straightening assembly 6. The position and height of the second pressure roller 602 are controlled by the second hydraulic cylinder 603. Similarly, the first pressure rollers 502 in the two sets of first straightening assemblies 5 contact the two sides of the profile respectively. Thus, the conveyor roller 102, the two first pressure rollers 502 and the second pressure roller 602 form a rectangular diameter roller straightening structure to straighten the entire profile.

[0032] Furthermore, when dealing with rectangular profiles of different sizes and specifications, this solution can be used to control the position of the second pressure roller 602 with the second hydraulic cylinder 603, thereby changing the distance between the second pressure roller 602 and the conveying roller 102. The first hydraulic cylinder 503 controls the corresponding first pressure roller 502 to move horizontally, thereby changing the distance between the two corresponding first pressure rollers 502. This can meet the straightening processing of rectangular door and window profiles of different sizes and specifications, with high straightening efficiency and flexibility.

[0033] Furthermore, most existing door and window profiles are made of aluminum alloy or aluminum-plastic alloy, which have low plasticity at room temperature. Simply applying mechanical force may result in residual stress in profiles with large bending areas, leading to secondary deformation and a relatively low straightening rate. Therefore, this solution adds a heating component 4 to the bottom of the conveyor 1. The heating rod 402 heats the air in the box 401, and the fan 403 blows the heat into the shell cavity formed by the side protective plate 2 and the top plate 3. Since the door and window profiles are being mechanically straightened in this shell cavity, the metal atoms of the aluminum alloy or aluminum-plastic alloy become more mobile after heating, and the deformation resistance is significantly reduced. This facilitates precise straightening by mechanical force, promotes the release of internal stress in the aluminum profiles, and avoids secondary deformation caused by residual stress after straightening.

[0034] 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.
