Description

Technical Field

[0001] This utility model relates to the field of door and window manufacturing technology, specifically to a folding device used in door and window manufacturing. Background Technology

[0002] Door and window processing belongs to the manufacturing industry. However, since doors and windows are provided to consumers or large engineering projects and require installation, door and window services must, to a certain extent, have door and window installation qualifications. This includes modifying and installing existing or new doors and windows. Old doors and windows can also have their opening and closing mechanisms changed. During the processing of doors and windows, sheet metal needs to be covered on the surface of the doors and windows to protect them. After attaching the sheet metal, there will usually be an extra distance, which needs to be bent using a bending machine.

[0003] In the folding process of door and window manufacturing, the quality of the folding directly depends on the accuracy and stability of the positioning. Traditional methods (such as relying on fixed blocks or manual experience for positioning) are unreliable and cannot be dynamically maintained as the reference point in the positioning stage when meeting high-standard folding requirements. This leads to the sheet metal easily slipping, shifting, or wrinkling at the moment of folding stress. This directly results in quality problems such as uneven folded edges and out-of-tolerance dimensions. In other words, defects in the positioning stage have become the core bottleneck restricting the improvement of folding quality and efficiency. Based on this, the applicant has designed a folding device for door and window manufacturing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a folding device for door and window production, which addresses the above-mentioned shortcomings.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a folding device for door and window production, comprising a working platform and a support plate disposed on the working platform. The support plate is provided with a limiting mechanism, a folding mechanism, and a pressing mechanism. The limiting mechanism includes a limiting plate for limiting the door / window and sheet metal. The limiting plate adopts an L-shaped structure and is slidably connected to the support plate and reset by several strong springs. The working platform is provided with a clearance groove adapted to the size of the limiting plate. The folding mechanism includes a T-shaped plate used in conjunction with the limiting plate and a first hydraulic cylinder for lifting the T-shaped plate. The pressing mechanism includes a pressure plate and a second hydraulic cylinder for lifting the pressure plate. The cylinder bodies of the first and second hydraulic cylinders are both fixedly mounted on the support plate.

[0006] Preferably, a slider is fixedly connected to the limiting plate, a groove is provided on the support plate, the slider slides in cooperation with the groove, the two ends of the strong spring are fixedly connected to the inner top wall of the slider and the groove respectively, and a positioning rod for limiting the height of the slider is fixedly connected to the inner top wall of the groove.

[0007] Preferably, the number of sliders and strong springs is set to two, and the two sliders and strong springs are symmetrically distributed on the limiting plate.

[0008] Preferably, the number of the first hydraulic cylinders is set to two.

[0009] Preferably, the working platform consists of a base and a support platform, with the support platform fixedly installed on the base, and the base having four support legs at its bottom.

[0010] Preferably, a rubber layer is provided at the bottom of the pressure plate.

[0011] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The folding device provided by this utility model effectively overcomes the problems of inaccurate positioning and low efficiency of traditional methods. Utilizing an automatically resetting L-shaped limiting plate, it changes the positioning mode that relies on manual experience, achieving rapid and accurate positioning. Through the dynamic movement of the limiting plate during the folding process, it solves the problem of instability caused by fixed blocks, ensuring the uniformity of folding quality. An innovative positioning and clamping mechanism fundamentally guarantees and improves the quality and efficiency of folding. Finally, through the coordinated operation of the hydraulically driven clamping and folding mechanism, it achieves high process efficiency, comprehensively improving the processing efficiency and product qualification rate of door and window folding.

[0017] Example 1 Please see Figure 1-5 This utility model provides a technical solution: a folding device for door and window production, including a working platform 1 and a support plate 2 disposed on the working platform 1. The working platform 1 consists of a base 101 and a support platform 102, with the support platform 102 fixedly installed on the base 101. The base 101 has four support legs at its bottom. The support plate 2 is provided with a limiting mechanism, a folding mechanism, and a pressing mechanism. The limiting mechanism includes a limiting plate 3 for limiting the door / window and sheet metal. The limiting plate 3 has an L-shaped structure and is slidably connected to the support plate 2 and reset by several strong springs 4. A slider 10 is fixedly connected to the limiting plate 3. The number of sliders 10 and strong springs 4 is set to two, and the two sliders 10 and strong springs 4 are symmetrically distributed on the limiting plate 3.

[0018] The support plate 2 is provided with a sliding groove 11, the slider 10 slides in the sliding groove 11, the two ends of the strong spring 4 are fixedly connected to the inner top wall of the slider 10 and the sliding groove 11 respectively, the inner top wall of the sliding groove 11 is fixedly connected to a positioning rod that limits the height of the slider 10, and the working platform 1 is provided with an avoidance groove 5 that matches the size of the limiting plate 3.

[0019] The folding mechanism includes a T-shaped plate 6 that cooperates with the limiting plate 3, and a first hydraulic cylinder 7 for lifting the T-shaped plate 6; the number of the first hydraulic cylinder 7 is set to two.

[0020] Working principle: When folding the edges of doors and windows, the doors and windows are placed on the support platform 102 and abutted against the horizontal edge of the limiting plate 3. Then, the cut sheet metal is placed on the doors and windows and abutted against the vertical plate of the limiting plate 3. The second hydraulic cylinder 9 is activated, which moves the pressure plate 8 down and fixes the doors, windows and sheet metal. Then, the first hydraulic cylinder 7 is activated, which moves the T-shaped plate 6 down and folds the extended sheet metal. During the folding process, the limiting plate 3 is pushed down, so that the limiting plate 3 still plays a limiting role during the folding process. After folding, the pressure plate 8 and the T-shaped plate 6 rise, and the limiting plate 3 returns to its original position through the strong spring 4. The rising height is controlled by the positioning rod to facilitate subsequent limiting, thereby improving the folding efficiency of doors and windows.
