[0002] A bending machine is a machine that can bend thin plates. A hydraulic bending machine includes a support, a worktable and a clamping plate.

Not only is the fixing stability poor, but bending is also inconvenient. Therefore, we propose a hydraulic bending machine that is easy to adjust the fixing angle. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution;

[0021] A hydraulic bending machine with an easily adjustable fixed angle includes a work support platform 1. The top of the work support platform 1 is fixedly connected to equidistantly distributed hydraulic cylinder fixing slots 4. A bending drive assembly is disposed inside the hydraulic cylinder fixing slots 4. A bending support platform 6 is fixedly connected to the inner bottom surface of the work support platform 1. A bending block 7 is fixedly connected to the top surface of the bending support platform 6. A rotating support rod 8 is fixedly connected to the right side of the inner bottom surface of the work support platform 1. An angle support adjustment assembly is disposed on the top surface of the rotating support rod 8. A lifting angle drive motor 9 is fixedly connected to the right side of the inner bottom surface of the work support platform 1. A lifting assembly is disposed on the output shaft of the lifting angle drive motor 9. A lifting angle adjustment assembly is disposed on the top surface of the lifting assembly.

[0022] Furthermore, the inner bottom surface of the working support platform 1 is fixedly connected with symmetrically distributed limiting and fixing rods 5, and the right side of the inner bottom surface of the working support platform 1 is fixedly connected with a lifting angle support platform 10. The front of the top surface of the lifting angle support platform 10 is provided with a lifting and rotating hole 19, and the rear of the top surface of the lifting angle support platform 10 is provided with a fixing and mounting hole 18.

[0023] Furthermore, the bending drive assembly includes a bending pressure rod 2, a bending hydraulic drive rod 3, and a bending hydraulic cylinder 17. The bending hydraulic cylinder 17 is fixedly connected to the inner side of the hydraulic cylinder fixing groove 4, and the bending hydraulic drive rod 3 is slidably connected to the inner bottom of the bending hydraulic cylinder 17. The bending pressure rod 2 is fixedly connected to the bottom surface of the bending hydraulic drive rod 3. Through the action of the bending drive assembly, the bending hydraulic cylinder 17 is used as a power source. The change in the internal liquid pressure drives the bending hydraulic drive rod 3 to slide up and down in the hydraulic cylinder. At the same time, when the bending hydraulic drive rod 3 moves up and down, it drives the bending pressure rod 2 to move synchronously, thereby applying a bending force to the sheet material placed on the bending block 7.

[0024] Furthermore, the angle support adjustment assembly includes a rotating support rod 8 and an angle rotating support plate 11. The bottom of the angle rotating support plate 11 is provided with a connecting rotating hole 21, and the rotating support rod 8 is rotatably connected to the inner side of the connecting rotating hole 21. The right side of the angle rotating support plate 11 is provided with a sliding groove, and the inner side of the sliding groove is slidably connected to a sliding connecting plate 22. Through the action of the angle support adjustment assembly, the angle rotating support plate 11 can rotate around the rotating support rod 8 as an axis to achieve angle adjustment. At the same time, the sliding connecting plate 22 plays a role in assisting the support of the angle rotating support plate 11. When the lifting angle adjustment assembly is working, the angle rotating support plate 11 and the lifting angle support plate 13 can work together to ensure full support for the bent plate surface.

[0025] Furthermore, the lifting assembly includes a lifting angle drive motor 9, a lifting support rod 12, a guide sliding rod 14, and a lifting screw 15. The output shaft of the lifting angle drive motor 9 is fixedly connected to the lifting screw 15. The lifting screw 15 is rotatably connected to the inner side of the lifting rotation hole 19. The lifting screw 15 is rotatably connected to the inner top surface of the working support platform 1. The guide sliding rod 14 is fixedly connected to the inner side of the fixed mounting hole 18. The guide sliding rod 14 is fixedly connected to the inner top surface of the working support platform 1. A threaded hole 23 is opened at the front of the lifting support rod 12. A connecting hole is provided at the rear. A lifting screw 15 is threadedly connected to the inner side of the threaded hole 23. A guide sliding rod 14 is slidably connected to the inner side of the connecting hole. A lifting angle adjustment component is provided on the outer side of the lifting support rod 12. Through the action of the lifting component, when the lifting angle drive motor 9 is started, its output shaft drives the lifting screw 15 to rotate. When the lifting screw 15 rotates, the lifting support rod 12 will move up and down along the screw due to the action of the thread. The guide sliding rod 14 provides guidance for the lifting and lowering of the lifting support rod 12, ensuring that its lifting and lowering process is stable and does not deviate.

[0026] Furthermore, the lifting angle adjustment component includes a lifting angle support plate 13 and a sliding connecting plate 22. The lifting angle support plate 13 is rotatably connected to the outer side of the lifting support rod 12. The lifting angle support plate 13 has a connecting groove, and the sliding connecting plate 22 is slidably connected inside the connecting groove. A bent plate 16 is fixedly connected to the top surface of the angle rotation support plate 11 and the lifting angle support plate 13. A bending groove 20 is opened on the top surface of the bending block 7, and the bent plate 16 is fixedly connected to the top surface of the bending block 7. Through the action of the lifting angle adjustment component, when the lifting support rod 12 is raised or lowered, it drives the lifting angle support plate 13 to be raised or lowered together. During the raising and lowering process, through the connection relationship between the sliding connecting plate 22 and the angle rotation support plate 11, the angle between the lifting angle support plate 13 and the angle rotation support plate 11 is adjusted in a coordinated manner to adapt to plates with different bending angles.

[0027] Working Principle: When this utility model is needed, according to the bending angle requirements of the sheet material to be bent, the lifting angle drive motor 9 drives the lifting assembly to adjust the height and angle of the lifting angle support plate 13 and the angle rotation support plate 11, so that the sheet material 16 is in a suitable position and angle to adapt to the shape of the sheet material after bending, preparing for full support of the sheet material. The sheet material to be bent is placed on the bending block 7, at which point the sheet material is in contact with the bending sheet material 16. The sheet material is initially positioned and supported by the adjusted angle support adjustment assembly, lifting assembly, and lifting angle adjustment assembly. The bending hydraulic cylinder 17 is activated, and the bending hydraulic drive rod 3 pushes the bending pressure rod 2 downward to apply pressure to the sheet material, causing the sheet material to bend at the bending groove 20 of the bending block 7. After bending is completed, the bending pressure rod 2 is raised, and the bent sheet material is removed, thus completing the bending process of the bending block 7.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
