[0002] Due to their high structural strength, corrosion resistance, and ease of processing, profiles are widely used in the construction industry, especially in the field of door and window manufacturing. In the production and manufacturing of doors and windows, in order to meet the market demand, the profile structure needs to be bent to improve the decorative effect and further enhance the structural strength of doors and windows, thus enriching the application of profiles in the field of doors and windows.

[0003] Currently, bending machines are commonly used to bend profiles. However, common bending machines are not conducive to adjusting the bending angle and are usually only used for bending the same type of profile, resulting in low applicability. Since there are many types of doors and windows, there are more requirements for the bending angle of the profiles. Therefore, it is necessary to design a bending device that can bend to multiple arcs to meet the structural requirements of the profiles during the manufacturing of doors and windows.

Furthermore, when changing the bending dies, other supporting structures can be adaptively adjusted to meet the feeding requirements during profile bending. Simultaneously, it ensures the effective use of the bending rollers after changing the bending dies. In addition, this bending device can position and limit the profile during the bending process, assisting the bending rollers in bending the profile, facilitating profile preparation and forming, and effectively solving the problems in the prior art.

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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a bending device for profile forming and processing, including a positioning plate 1, on which a replaceable bending die 2 is installed. Preferably, the bending die 2 is fixed to the positioning plate 1 with bolts. The bending die 2 can be replaced by removing the bolts. When the diameter of the bending die 2 used is different, the angle of the profile bent by it is different. The bending die 2 can be installed and set according to the bending requirements.

[0025] A rotary drive is installed in the middle of the positioning plate 1, and an electric telescopic component is installed on the drive shaft of the rotary drive. A positioning seat 7 is installed at the telescopic end of the electric telescopic component, and a bending roller 8 is installed inside the positioning seat 7. The rotary drive drives the electric telescopic component to rotate on the positioning plate 1, so that the bending roller 8 installed at the end of the electric telescopic component rotates around the bending die 2, placing the profile between the bending die 2 and the bending roller 8. During the rotation of the bending roller 8, a force is applied to the profile, causing the profile to bend and deform along the bending die 2, which facilitates the bending and forming of the profile.

[0026] The rotary drive includes a motor assembly 3 mounted on the positioning plate 1, and a reducer 4 is mounted on the output shaft of the motor assembly 3. An electric telescopic component is mounted on the output shaft of the reducer 4. The reducer 4 is used to increase the output torque of the output shaft in the rotary drive. When in use, it controls the operation of the motor assembly 3, and the output shaft of the reducer 4 is driven by the motor assembly 3 to rotate, so that the electric telescopic component can drive the bending roller 8 to rotate around the bending die 2 to bend the profile.

[0027] A mounting base 5 is installed on the output shaft of the reducer 4. The electric telescopic component includes a hydraulic cylinder 6 installed in the mounting base 5. A positioning seat 7 is fixed at the telescopic end of the hydraulic cylinder 6. After the bending die 2 is replaced, the length of the hydraulic cylinder 6 can be adjusted according to the change in the diameter of the bending die 2, so that the profile can be placed between the bending die 2 and the bending roller 8 for bending processing. The hydraulic cylinder 6 is used to adjust the position of the bending roller 8 so that the bending roller 8 can be adapted to the replaced bending die 2 for use.

[0028] A positioning frame 9 is fixed to the side of the positioning plate 1. Preferably, a support frame 18 is installed on the lower side of the positioning plate 1 and the lower side of the positioning frame 9 to support and position them. The positioning frame 9 is provided with a position-adjustable placement frame 10. The placement frame 10 is used for support and limiting when the profile is bent. The placement frame 10 is provided with a positioning component for positioning the profile. The positioning component includes a limiting frame 13. The limiting frame 13 is located at the end of the placement frame 10 away from the positioning plate 1. The placement frame 10 is provided with a screw 14 for adjusting the position of the limiting frame 13. After the profile is placed in the placement frame 10, the position of the limiting frame 13 is adjusted by the screw 14 so that the limiting frame 13 and the placement frame 10 clamp the profile and position it, thereby reducing the displacement of the profile during bending.

[0029] A positioning frame 11 is fixed to the lower side of the placement frame 10. Several sets of connecting parts are provided between the positioning frame 9 and the placement frame 10. After changing the bending die 2, the position of the placement frame 10 can be adjusted adaptively according to the size of the bending die 2. The connecting parts include a connecting plate 12. One end of the connecting plate 12 is fixed to the lower side of the positioning frame 9, and the other end of the connecting plate 12 is slidably set in the positioning frame 11. When adjusting the position of the placement frame 10, the connecting plate 12 plays a positioning and guiding role. At the same time, the connecting plate 12 is used for supporting and positioning the placement frame 10. The position of the placement frame 10 can be adjusted to be tangent to the bending die 2. After that, after the profile is placed in the placement frame 10, one side of the profile is attached to the outside of the bending die 2, which makes it easier to control the bending roller 8 to bend the profile. The positioning frame 11 is equipped with positioning screws for positioning the connecting plate 12. The positioning screws are used for positioning the connecting plate 12 after the position is adjusted.

[0030] A limiting frame is provided on the side of the positioning plate 1 corresponding to the position of the placement frame 10, and the limiting frame and the bending die 2 are arranged in the same direction. The limiting frame is used to limit the end of the profile. An installation frame 17 is installed on the lower side of the positioning plate 1. The limiting frame includes an adjustment plate 15 that is slidably disposed in the installation frame 17, and a limiting plate 16 is fixed at the end of the adjustment plate 15. When processing the same batch of profiles, the limiting plate 16 limits the end of the profile so that the bending points are the same. The position of the limiting plate 16 can be adjusted by sliding the adjustment plate 15 within the installation frame 17, which facilitates the adjustment of the profile bending position. A fastening screw for positioning the adjustment plate 15 is installed on the installation frame 17. The fastening screw is used to position the adjustment plate 15 after the position is adjusted.
