The precision of the bending process directly affects the structural strength and appearance quality of the door and window frame, ensuring good sealing, aesthetics, and durability after installation. Therefore, efficient and precise bending processes are crucial for improving the overall quality of aluminum alloy doors and windows.

After completing the bending, the worker needs to remove the workpiece, measure it with an angle measuring tool, and then adjust it according to the measurement results. If the bending angle deviation is large, it needs to be adjusted repeatedly and bent again, which is easily affected by the operator's experience, the accuracy of the measuring tool, and human factors, thereby reducing the processing consistency.

[0004] To solve the above problems, a bending device for aluminum alloy door and window production is proposed to ensure the accuracy and consistency of the aluminum alloy bending angle and avoid product quality fluctuations caused by human error. CONTENT OF THE INVENTION

[0032] Please refer to Figure 1 and Figure 2 The present application proposes a bending device 10 for aluminum alloy door and window production, comprising a base 100, a hydraulic mechanism 200, a camera 300 and a control mechanism 400, the base 100 is provided with a bending groove 110, the bending groove 110 extends along a straight line, and an aluminum alloy plate is placed on the bending groove 110; the hydraulic mechanism 200 comprises a hydraulic cylinder 210 and a pressing head 220, the hydraulic cylinder 210 can drive the pressing head 220 to move towards the bending groove 110, so as to exert a bending pressure on the aluminum alloy plate towards the bending groove 110; the camera 300 is arranged in the extension direction of the bending groove 110, the camera 300 observes in the direction of the bending groove 110, and the bending groove 110 is V-shaped; the control mechanism 400 is electrically connected with the hydraulic cylinder 210 and the camera 300, the control mechanism 400 is used for receiving the bending image data collected by the camera 300, and controlling the stroke of the hydraulic cylinder 210 moving towards the bending groove 110 based on the measurement result of the bending angle.

[0033] Specifically, the bending groove 110 extends along a straight line. The aluminum alloy plate is placed on the bending groove 110, and the shape of the bending groove 110 is designed as a V-shaped structure. The V-shaped structure of the bending groove 110 helps to fix the aluminum alloy plate and ensures that it will not displace during the bending process. The hydraulic cylinder 210 can drive the lower pressing head 220 to move towards the bending groove 110, apply bending pressure, and then bend the aluminum alloy plate. The use of the hydraulic cylinder 210 enables precise control of the pressure during the bending process, and the bending force has high stability, which can adapt to aluminum alloy plates of different thicknesses or specifications.

[0034] The camera 300 is arranged in the extension direction of the bending groove 110 and observes in the direction of the bending groove 110. The camera 300 monitors the bending angle of the aluminum alloy plate in real time during the bending process. The shooting direction of the camera 300 is consistent with the direction of the bending groove 110, which ensures accurate capture of the bending process.

[0035] It should be noted that the existing aluminum alloy door and window bending equipment generally relies on manual measurement of the bending angle, resulting in a large error in the bending angle. In the present application, the camera 300 collects image data during the bending process, and the control mechanism 400 automatically analyzes the bending angle. This not only improves the bending accuracy, but also saves the time and effort of manual measurement. This automatic angle detection method enables the equipment to adjust the parameters in real time during the bending process, avoiding errors caused by human factors and ensuring that the bending angle of each aluminum alloy door and window component meets the specified requirements.

[0036] Reference should be made to Figure 1 In an embodiment, the lower pressing head 220 has a V-shaped head 221 that can extend into the bending groove 110.

[0037] Specifically, the lower pressing head 220 has a V-shaped head 221 that can extend into the bending groove 110. The V-shaped head 221 is designed to match the V-shaped structure of the bending groove 110, which can ensure better contact between the lower pressing head 220 and the aluminum alloy plate during the bending process and apply uniform bending pressure. By extending the V-shaped head 221 into the bending groove 110, the lower pressing head 220 can accurately bend the aluminum alloy plate in the bending groove 110, avoiding problems such as plate misalignment or uneven pressure caused by the mismatch between the lower pressing head 220 and the bending groove 110. This design enhances the support and guidance of the lower pressing head 220 to the aluminum alloy plate, further improving the accuracy and stability of the bending process.

[0038] In an embodiment, the control mechanism 400 includes an algorithm module for calculating the bending angle of the aluminum alloy plate based on the image data collected by the camera 300.

[0039] Specifically, the algorithm module is configured to calculate the bending angle of the aluminum alloy plate according to the image data collected by the camera 300. The camera 300 collects images between the aluminum alloy plate and the bending groove 110 in real time during the bending process, and the algorithm module analyzes the image data through image processing technology to extract the bending angle information. The algorithm module uses edge detection and angle calculation technology to convert the collected images into quantifiable bending angles, thereby providing accurate data support for the subsequent control system and automatically adjusting the working parameters of the hydraulic system.

[0040] In an embodiment, the bending device 10 for aluminum alloy door and window production further comprises a display screen 500, which is arranged on the base 100.

[0041] Specifically, the display screen 500 is configured to display real-time data of the bending angle and automatically adjust the movement stroke of the hydraulic cylinder 210 according to the deviation of the bending angle from the set target angle, so as to ensure that the bending angle meets the set requirements.

[0042] In an embodiment, the base 100 is provided with a first surface 120 and a second surface 130 at the position of the bending groove 110, the first surface 120 and the second surface 130 are connected and form a V shape, and the shooting direction of the camera 300 is perpendicular to the first surface 120 and the second surface 130.

[0043] Specifically, the angle between the first surface 120 and the second surface 130 is 60°-120°, and preferably 90°. The shooting direction of the camera 300 is consistent with the extension direction of the bending groove 110, and the shooting direction of the camera 300 is perpendicular to the first surface 120 and the second surface 130. By shooting perpendicularly to the first surface 120 and the second surface 130 of the bending groove 110 through the camera 300, the error caused by the shooting angle is avoided, the accuracy of the image data is ensured, and accurate input data is provided for subsequent calculation of the bending angle. For example, when the angle between the first surface 120 and the second surface 130 is 90°, the camera 300 can accurately and perpendicularly capture the bending state of the aluminum alloy plate inside the bending groove 110. By keeping the shooting direction of the camera 300 perpendicular to the angle of the bending groove 110, image distortion or angle error can be avoided, thereby providing more accurate image data for the control system. The algorithm module calculates the bending angle of the aluminum alloy plate according to the image data obtained by the camera 300. In order to ensure the accuracy of the image of the camera 300, the following algorithm is used to calculate the angle:

[0044] Suppose that the edge data of the aluminum alloy plate during bending is extracted from the image captured by the camera 300 through image processing technology, and the bending angle is calculated. Two edges L1 and L2 of the bending groove 110 are set, L1 and L2 are two lines generated during the bending process, and the angle is θ. The direction angle of the line segment is calculated: the direction angle of the line segment L1 and L2 can be calculated by the following formula:

[0045]

[0046]

[0047] wherein (x1, y1) and (x2, y2) are the coordinates of the two end points of the line segment L1. (x3, y3) and (x4, y4) are the coordinates of the two end points of the line segment L2.

[0048] The bending angle θ can be calculated by the following formula, θ = |θ1-θ2|. The difference Δθ between the real-time calculated bending angle θcurrent and the target bending angle θtarget is used to adjust the stroke of the hydraulic cylinder 210 to ensure that the bending angle reaches the target value. The formula is as follows Δθ = θ target -θ current k is a constant representing the proportional relationship between the bending angle and the stroke of the hydraulic cylinder 210. The stroke adjustment formula of the hydraulic cylinder 210 is ΔH = k · Δθ. Through this formula, the control system of the control mechanism 400 can automatically adjust the movement stroke of the hydraulic cylinder 210 according to the deviation between the actually measured bending angle and the target angle, to ensure accurate control of the bending angle.

[0049] The hydraulic mechanism 200 includes a driving assembly 230, which can adjust the fixed height of the hydraulic cylinder 210.

[0050] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those of ordinary skill in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Accordingly, the application is not to be limited to these embodiments shown herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
