Description

Technical Field

[0001] This utility model relates to the field of kettle manufacturing technology, and in particular to a profile bending device for kettle manufacturing. Background Technology

[0002] In the kettle manufacturing process, profile bending is a core process for preparing key components such as the kettle shell, handle, and spout connection.

[0003] Existing devices generally lack a synchronized "bending-positioning" mechanism, relying mostly on simple side stops or manual assistance for positioning. When the hydraulic cylinder drives the bending press to perform the bending operation, the kettle profile (mostly thin stainless steel or aluminum alloy sheets) is prone to lateral shift or vertical swaying due to uneven force. For example, when the bending force acts on the middle of the profile, the two ends are prone to warping or lateral displacement, causing the angle deviation and positional offset of the bent part to exceed the assembly tolerance range of the kettle components. This not only increases the subsequent rework rate but may also cause the profile to be scrapped due to positioning errors, affecting the stability of product quality. In view of this, we provide a profile bending device for kettle production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a profile bending device for kettle production, which solves the technical problem of poor bending accuracy caused by profile deviation or wobbling during kettle production bending. It achieves the effect of simultaneously stabilizing and limiting the profile plate to prevent deviation and ensure bending accuracy during profile bending, thereby improving the processing quality of kettle profiles.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a profile bending device for kettle production, including a back frame installed on the rear side of the top of the processing table.

[0006] A hydraulic cylinder is installed at the top of the back frame, and a mounting bracket is installed at the telescopic end of the hydraulic cylinder. Toothed plates are installed on both sides of the bottom of the mounting bracket. Supports are installed on both sides of the top of the processing table. A linkage shaft is rotatably connected between each set of supports and the back frame. A gear that meshes with the toothed plate is installed at the end of the linkage shaft away from the support. Multiple sets of connecting parts are installed on the outer wall of the linkage shaft. A buffer spring is connected inside the connecting parts. A fixing part that fits against the profile plate is installed at the bottom of the buffer spring to fix the profile plate while bending.

[0007] Preferably, an asynchronous motor is installed on the back of the processing table, and a lead screw connected to the inside of the processing table is installed on the output shaft of the asynchronous motor. Support rods distributed on both sides of the lead screw are installed inside the processing table. A movable connecting long seat that is slidably connected to the two sets of support rods is threaded on the lead screw. A placement seat is installed on one side of the movable connecting long seat to the top of the processing table, and a lower bending mold is installed on the top of the placement seat.

[0008] Preferably, an upper bending pressure piece adapted to the lower bending mold is installed in the middle of the bottom of the mounting frame, and when the upper bending pressure piece contacts the profile plate, the bottom end of the fixing piece is in contact with the top two sides of the profile plate.

[0009] Preferably, the top of the processing table is provided with a through square groove that is adapted to the toothed plate. When the two sets of toothed plates extend into the processing table, they are distributed on the sides of the two sets of support rods.

[0010] Preferably, the fastener is made of silicone and has a serrated bottom.

[0011] Preferably, the lead screw is located diagonally below the placement seat, and the lower bending die is fixed to the placement seat by bolts.

[0012] By means of the above technical solution, this utility model provides a profile bending device for kettle production, which has at least the following beneficial effects: 1. By setting a bending structure, this utility model can simultaneously achieve stable positioning of the profile plate when bending the profile used for kettle production, effectively preventing the profile from shifting or shaking during the bending process, ensuring the accuracy of the bending part, and at the same time, the buffer structure can also alleviate the force during the bending process, improving the processing quality of the kettle profile.

[0013] 2. By setting up a movable structure, this utility model can not only conveniently adjust the processing position according to the bending requirements of different specifications of kettle profiles, thereby improving the bending efficiency of the profiles, but also the mold installation method is relatively convenient, and the mold can be quickly assembled and disassembled, thereby improving the overall production efficiency.

[0017] 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.

[0018] Example 1

[0019] Existing technologies address the problem of poor bending accuracy caused by profile misalignment or wobbling during kettle production. This embodiment provides a profile bending device for kettle production that simultaneously stabilizes and limits the profile during bending to prevent misalignment, ensures bending accuracy, and improves the processing quality of kettle profiles. Please refer to... Figure 1 - Figure 5 The profile bending device for kettle production includes a back frame 2 installed on the rear side of the top of the processing table 1. The top of the processing table 1 has a through square groove that matches the toothed plate 5, which can provide precise guidance for the toothed plate 5 to move up and down, ensuring that its vertical lifting does not deviate, thereby ensuring stable meshing between the toothed plate 5 and the gear 8, and creating conditions for the fixing part 11 to fix the profile synchronously.

[0020] Existing profile bending devices used in kettle production generally lack a synchronous linkage mechanism of "bending-positioning". Most rely on simple side stops or manual assistance for positioning, which makes the profiles prone to lateral displacement or vertical swaying due to uneven force. In order to solve the above problems.

[0021] A hydraulic cylinder 3 is installed at the top of the back frame 2. A mounting frame 4 is installed at the telescopic end of the hydraulic cylinder 3. An upper bending pressure piece adapted to the lower bending die 17 is installed at the bottom center of the mounting frame 4. This provides a precise pressure and forming structure for bending the kettle profile, ensuring that the bending angle and shape of the profile meet the processing requirements. When the upper bending pressure piece contacts the profile plate, the bottom end of the fixing piece 11 fits against the top two sides of the profile plate, thereby achieving synchronous "bending-positioning" and preventing the profile from shifting or shaking during bending, ensuring the accuracy of the bending part. Toothed plates 5 are installed on both sides of the bottom of the mounting frame 4. When the two sets of toothed plates 5 extend into the processing table 1, they are distributed on the sides of the two sets of support rods 14, avoiding interference with the movable connecting seat 15 that slides along the support rods 14, ensuring that the movable structure can adjust the processing position normally. Supports 6 are installed on both sides of the top of the processing table 1. Each set of supports 6 is rotatably connected to the back frame 2 by a linkage shaft 7. A gear 8 that meshes with the toothed plate 5 is installed on the end of the linkage shaft 7 away from the support 6. Multiple sets of connecting parts 9 are installed on the outer wall of the linkage shaft 7. A buffer spring 10 is connected inside the connecting part 9. A fixing part 11 that fits against the profile plate is installed at the bottom of the buffer spring 10 to fix the profile plate while bending. The fixing part 11 is made of silicone to avoid rigid contact with the water bottle profile, prevent the profile surface from being scratched or dented, and protect the appearance and integrity of the profile. Its bottom end has a serrated structure, which can increase the contact friction with the profile plate, strengthen the bonding and fastening effect, and further prevent lateral displacement or up-and-down shaking when the profile is bent, ensuring positioning stability and bending accuracy.

[0022] During the process of preparing the profile for bending, the hydraulic cylinder 3 drives the mounting frame 4 to descend. The upper bending pressure piece at the bottom center of the mounting frame 4 moves closer to the lower bending die 17. At the same time, the toothed plates 5 on both sides of the bottom of the mounting frame 4 descend along the square groove at the top of the processing table 1 and mesh with the gear 8, thereby driving the linkage shaft 7 to rotate. The connecting piece 9 on the outer wall of the linkage shaft 7 rotates with it, causing the buffer spring 10 inside the connecting piece 9 to drive the fixing piece 11 to fit against the top two sides of the profile plate to achieve synchronous fixing. Then, the upper bending pressure piece and the lower bending die 17 cooperate to complete the profile bending. The buffer spring 10 synchronously relieves the bending force, thereby improving the bending stability and the production quality of the kettle.

[0023] Example 2

[0024] Based on Example 1, such as Figure 1 - Figure 5 As shown, based on the existing technology, when bending the profiles of kettle production, the profiles are prone to deviation or shaking, resulting in poor bending accuracy. However, the bending molds of the existing devices are mostly fixed installation structures. If the processing position needs to be adjusted to adapt to different specifications of profiles, the molds need to be disassembled and the installation reference needs to be recalibrated, which reduces bending efficiency. Therefore, this device is also equipped with a structure that allows for easy movement of the molds.

[0025] The bending dies of existing profile bending devices used in kettle production are mostly fixed installation structures. When the processing position needs to be adjusted to adapt to different specifications of profiles, the dies need to be disassembled and the installation reference needs to be recalibrated, which reduces the bending efficiency of the profiles. In order to solve the above problems,

[0026] An asynchronous motor 12 is installed on the back of the processing table 1. A lead screw 13 connected to the inside of the processing table 1 is installed on the output shaft of the asynchronous motor 12. The lead screw 13 is distributed below the placement seat 16 to prevent the flying debris generated during bending from falling into the threaded line on the lead screw 13, ensuring the smooth movement of the placement seat 16. Support rods 14 distributed on both sides of the lead screw 13 are installed inside the processing table 1. A movable connecting long seat 15 is threaded on the lead screw 13 and slidably connected to the two sets of support rods 14. One side of the movable connecting long seat 15 extends to the top of the processing table 1 and a placement seat 16 is installed. A lower bending die 17 is installed at the top of the placement seat 16. The lower bending die 17 is fixed to the placement seat 16 by bolts, realizing convenient assembly and disassembly of the die to adapt to different profiles, and ensuring that the die is stable and does not shift during bending, thus ensuring processing accuracy.

[0027] The lower bending die 17 is fixed to the placement seat 16 by bolts, thereby realizing the stable and convenient assembly and disassembly of the lower bending die 17. The asynchronous motor 12 is started, and its output shaft drives the lead screw 13 to rotate, so that the movable connecting long seat 15 on the lead screw 13 slides along the support rod 14 inside the processing table 1, thereby driving the placement seat 16 extending to the top of the processing table 1 and the lower bending die 17 on the placement seat 16 to the processing position of the matching profile. This not only allows for safe and convenient die replacement, but also allows for adjustment of the bending position according to requirements, thereby improving bending efficiency.
