Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending fixture technology, and in particular to an integrated metal bracket bending fixture. Background Technology
[0002] Bending fixtures are specialized tools or devices used to assist in the precise bending of metal sheets or supports on bending machines (such as hydraulic bending machines, CNC bending machines, etc.). They typically include dies (upper and lower dies), clamps, positioning devices, guide mechanisms, etc., to ensure the accuracy, efficiency, and safety of the bending process.
[0003] Most traditional metal bracket bending fixtures can only bend at fixed angles. If the metal bracket needs to be bent at multiple angles, different molds need to be changed to achieve different angle bending. This not only increases the bending time of the metal bracket, resulting in slow processing efficiency, but also causes positioning accuracy problems due to the constant changing of molds, resulting in low product consistency. Utility Model Content
[0004] To address the issue that most traditional metal bracket bending fixtures can only bend at fixed angles, and that different molds are needed to achieve different angles if the metal bracket needs to be bent at multiple angles, which increases the bending time and causes positioning accuracy problems, resulting in low product consistency, this utility model provides an integrated metal bracket bending fixture.
[0005] This utility model is achieved by the following technical solution: an integrated metal bracket bending fixture, including a worktable, a bending component for bending the metal bracket is provided at the top of the worktable, the bending component includes a first roller and a second roller, the metal bracket is located between the first roller and the second roller, a rotatable connecting frame is fixed to the bottom end of the second roller, and a pair of limiting components for fixing the metal bracket are also provided at the top of the worktable.
[0006] With the above technical solution, the metal bracket is placed between the first roller and the second roller, and the rotatable connecting frame drives the second roller to rotate circumferentially by a corresponding angle according to the required bending angle of the metal bracket.
[0007] As a further improvement to the above solution, a fixing block is fixedly connected to the top of the worktable, an L-shaped plate is fixedly connected to the top of the fixing block, a pair of horizontal plates are fixedly connected to the inner side of the L-shaped plate, a central shaft is rotatably connected to the top of the inner side of the L-shaped plate, the central shaft extends through to the bottom of the worktable, a servo motor coaxially connected to the central shaft is fixedly connected to the bottom of the worktable, a pair of connecting brackets are fixedly connected to the outer side of the central shaft, the other ends of the pair of connecting brackets are connected to each other through a fixing shaft, the second roller is fixedly connected to the top of the fixing shaft, and the first roller is rotatably connected to the top of the L-shaped plate.
[0008] Through the above technical solution, the activation of the servo motor can drive the central shaft to rotate, causing a pair of connecting frames fixed to the outside of the central shaft to rotate synchronously. Since the pair of connecting frames are connected by a fixed shaft, and the second roller is fixed to the top of the fixed shaft, the second roller can rotate circumferentially around the central shaft and bend the metal bracket located between the first roller and the second roller.
[0009] As a further improvement to the above solution, the limiting component includes a first limiting frame and a second limiting frame. The bottom end of the first limiting frame is fixedly connected to a first fixing post, and the bottom end of the first fixing post is fixedly connected to the top of the worktable. The bottom end of the second limiting frame is fixedly connected to a second fixing post, and the other end of the second fixing post is fixedly connected to the bottom end of the fixed shaft.
[0010] Through the above technical solution, the first limiting frame can provide support and limit the rear part of the metal bracket bending point. Since the second limiting frame is connected to the fixed shaft, it will rotate with the front part of the bending and provide support and limit the part.
[0011] As a further improvement to the above scheme, the first limiting frame and the second limiting frame are located on the same horizontal plane and are parallel to each other.
[0012] As a further improvement to the above solution, an electric telescopic rod is fixedly connected to the top of the workbench, and a rack for driving the first roller to rotate is fixedly connected to the output end of the electric telescopic rod. The outer side of the first roller is provided with meshing teeth that mesh with the rack. A limit block is fixedly connected to the side of the first roller that contacts the metal bracket.
[0013] Through the above technical solution, the setting of the limiting block can limit and support the metal bracket before bending, and avoid the metal bracket having a certain gap between the first roller and the second roller, which would affect the accuracy of the bending angle.
[0014] The electric telescopic rod drives the rack to move to the left. Because the meshing teeth fixed to the outside of the first roller mesh with the rack, the first roller rotates as the electric telescopic rod moves, causing the limiting block to disengage from the metal bracket, making it easier to remove the bent metal bracket from between the first and second rollers.
[0015] As a further improvement to the above solution, an angle scale is provided on the top of the first roller.
[0016] The above technical solution allows staff to visually see the bending angle of the metal bracket.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. This utility model uses a first roller and a second roller, and places a metal bracket between the first roller and the second roller. At this time, the rotatable connecting frame drives the second roller to rotate in a circle, thereby applying pressure and bending the metal bracket. The angle of rotation of the connecting frame is the required bending angle of the metal bracket. With a simple structural design, multi-angle bending of the metal bracket can be achieved without replacing parts.
[0019] 2. This utility model can limit and support the metal bracket before bending by setting the limiting block, so as to avoid the metal bracket having a certain gap between the first roller and the second roller, which would affect the accuracy of the bending angle; the electric telescopic rod drives the straight rack to move, thereby causing the limiting block to disengage from the metal bracket, making it convenient to pick up the bent metal bracket.

Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] Please combine Figures 1-4This embodiment of an integrated metal bracket bending fixture includes a workbench 1. The top of the workbench 1 is provided with a bending assembly for bending the metal bracket. The bending assembly includes a first roller 2 and a second roller 3. The metal bracket is located between the first roller 2 and the second roller 3. The bottom end of the second roller 3 is fixedly connected to a rotatable connecting frame 4. The top of the workbench 1 is also provided with a pair of limiting components for fixing the metal bracket.
[0028] With the first roller 2 and the second roller 3 in place, the metal bracket is placed between the first roller 2 and the second roller 3 and fixed by the limiting component. At this time, the second roller 3 is driven to rotate in a circle by the rotatable connecting frame 4, thereby applying pressure and bending the metal bracket. The angle of rotation of the connecting frame 4 is the bending angle required for the metal bracket.
[0029] Combination Figure 1 , Figure 2 and Figure 4 A fixing block 5 is fixed to the top of the worktable 1. An L-shaped plate 6 is fixed to the top of the fixing block 5. A pair of horizontal plates 7 are fixed to the inner side of the L-shaped plate 6. A central shaft 8 is rotatably connected to the top of the inner side of the L-shaped plate 6. The central shaft 8 extends through to the bottom of the worktable 1. A servo motor 9 coaxially connected to the central shaft 8 is fixed to the bottom of the worktable 1. A pair of connecting brackets 4 are fixed to the outer side of the central shaft 8. The other ends of the pair of connecting brackets 4 are connected through a fixing shaft 10. A second roller 3 is fixed to the top of the fixing shaft 10. A first roller 2 is rotatably connected to the top of the L-shaped plate 6.
[0030] By activating the servo motor 9 located at the bottom of the workbench 1, the central shaft 8 located inside the L-shaped plate 6 is driven to rotate, causing the pair of connecting frames 4 fixed to the outside of the central shaft 8 to rotate synchronously. Since the pair of connecting frames 4 are connected by the fixed shaft 10, and the second roller 3 is fixed to the top of the fixed shaft 10, the second roller 3 can rotate in a circle around the central shaft 8 as the axis, and apply pressure to bend the metal bracket located between the first roller 2 and the second roller 3.
[0031] Combination Figure 2 The limiting assembly includes a first limiting frame 11 and a second limiting frame 12. The bottom end of the first limiting frame 11 is fixedly connected to a first fixing post 13, and the bottom end of the first fixing post 13 is fixedly connected to the top of the worktable 1. The bottom end of the second limiting frame 12 is fixedly connected to a second fixing post 14, and the other end of the second fixing post 14 is fixedly connected to the bottom end of the fixed shaft 10.
[0032] The first limiting bracket 11 can provide support and limit the rear part of the bending point of the metal bracket;
[0033] Because the second limiting frame 12 is connected to the fixed shaft 10, when the connecting frame 4 drives the second roller 3 and the fixed shaft 10 to rotate, the second limiting frame 12, which is fixed to the bottom of the fixed shaft 10, will rotate synchronously to support and limit the front part of the bending point.
[0034] Combination Figure 2 and Figure 3 An electric telescopic rod 15 is fixedly connected to the top of the workbench 1. A rack 16 for driving the first roller 2 to rotate is fixedly connected to the output end of the electric telescopic rod 15. The outer side of the first roller 2 is provided with meshing teeth 17 that mesh with the rack 16. A limit block 18 is fixedly connected to the side of the first roller 2 that contacts the metal bracket.
[0035] By fixing a limiting block 18 to the side of the first roller 2 that contacts the metal bracket, the limiting block 18 can provide limiting support for the metal bracket before bending, thus avoiding a certain gap between the metal bracket and the first roller 2 and the second roller 3, which would affect the accuracy of the bending angle.
[0036] When the equipment completes the bending, the electric telescopic rod 15 on the top of the workbench 1 is activated to drive the rack 16 to move to the left. Because the meshing teeth 17 fixed to the outer side of the first roller 2 mesh with the rack 16, the first roller 2 rotates as the rack 16 moves, and the limiting block 18 disengages from the metal bracket, thereby releasing the limiting fixation between the metal parts, making it convenient for the workers to remove the bent metal bracket from between the first roller 2 and the second roller 3.
[0037] Combination Figure 3 and Figure 4 An angle scale 19 is set on the top of the first roller 2.
[0038] By setting an angle scale 19 on the top of the first roller 2, staff can easily see the bending angle of the metal bracket.
[0039] The implementation principle of the integrated metal bracket bending fixture in this application embodiment is as follows:
[0040] Before bending, first pass the metal bracket through the first limiting frame 11, then through the limiting block 18 fixed to the outside of the first roller 2 and the second roller 3, and finally through the second limiting frame 12 and align it with the bending point.
[0041] At this time, the servo motor 9 is turned on to drive the central shaft 8 to rotate, so that the pair of connecting frames 4 fixed to the outside of the central shaft 8 rotate synchronously. Since the pair of connecting frames 4 are connected by the fixed shaft 10, and the second roller 3 is fixed to the top of the fixed shaft 10, and the second limit frame 12 is fixed to the bottom of the fixed shaft 10, the second roller 3, the fixed shaft 10, and the second limit frame 12 all rotate in a circle around the central shaft 8, so as to apply pressure and bend the metal bracket between the first roller 2 and the second roller 3.
[0042] Meanwhile, staff can use the angle scale 19 set on the top of the first roller 2 to determine whether the bending angle of the metal bracket meets the standard;
[0043] Then, the electric telescopic rod 15 on the top of the workbench 1 is activated to move the rack 16 to the left. Because the meshing teeth 17 fixed to the outer side of the first roller 2 mesh with the rack 16, the first roller 2 rotates as the rack 16 moves, and the limiting block 18 disengages from the metal bracket, thereby releasing the limiting fixation between the metal parts, making it convenient for the workers to remove the bent metal bracket from between the first roller 2 and the second roller 3.
[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
