[0023] Example

[0024] Please refer to Figure 1 This embodiment provides a deformation correction device for a large-diameter flange of a container, which includes a base plate 1, a dynamic pressure mechanism, and a static pressure mechanism. The base plate 1 is the basic support platform for the entire correction device. The base plate 1 is made of high-strength alloy material, which has sufficient strength and stability to ensure the smooth progress of the correction process. A support block 11 is also provided at the bottom of the base plate 1. The support block 11 makes the correction device more stable during placement and movement, avoiding safety problems caused by shaking or tilting. The surface of the base plate 1 is also provided with anti-slip texture to increase the friction between it and the flange 4, preventing the flange 4 from sliding during the correction process.

[0025] In this embodiment, both the dynamic pressure mechanism and the static pressure mechanism are mounted on the base plate 1. The dynamic pressure mechanism also includes a dynamic pressure drive component 21 and a first annular plate 22. The dynamic pressure drive component 21 is connected to the first annular plate 22. The dynamic pressure drive component 21 can be a hydraulic cylinder or other device capable of driving the first annular plate 22 to reciprocate linearly. In this embodiment, the dynamic pressure drive component 21 is a dynamic pressure hydraulic cylinder. The dynamic pressure hydraulic cylinder is fixed to the base plate 1 by a first mounting plate 23. That is, the first mounting plate 23 is fixed to the base plate 1, and the dynamic pressure hydraulic cylinder is fixed to the first mounting plate 23. In order to improve the stability of the dynamic pressure mechanism, a first reinforcing rib 24 is also provided between the first mounting plate 23 and the base plate 1.

[0026] In this embodiment, the static pressure mechanism includes a second annular plate 31 and a second mounting plate 32. The second mounting plate 32 is fixed to the base plate 1, and the second annular plate 31 is fixed to the second mounting plate 32. To improve the stability of the static pressure mechanism, the second mounting plate 32 is also provided with a second reinforcing rib 33. It should be noted that both the dynamic pressure mechanism and the static pressure mechanism adopt an annular plate design, enabling the straightening device to adapt to flanges 4 of different diameters, thereby improving the applicability and flexibility of the device.

[0027] When straightening the large-diameter flange 4, the flange 4 is first placed between the first annular plate 22 and the second annular plate 31. Then, the hydrodynamic cylinder extends until the first annular plate 22 and the second annular plate 31 clamp the flange 4. The hydrodynamic cylinder continues to extend, using the first annular plate 22 to apply pressure to the large-diameter flange 4 to achieve the straightening purpose. When the flange 4 returns to its original position, the straightening is complete, and the hydrodynamic cylinder retracts until the first annular plate 22 disengages from the large-diameter flange 4, so that the flange 4 can be lifted away. It should be noted that a pressure gauge can also be installed in the hydraulic system to monitor and provide feedback on pressure changes during the straightening process in real time, ensuring the accuracy and safety of the straightening process.

[0028] In this embodiment, the inner side of the first annular plate 22 and the inner side of the second annular plate 31 are both set on the scale line, that is, set along the concave side of the annular plate. In use, the operator can obtain the contact length between the large diameter flange 4 and the annular plate according to the scale, so as to accurately adjust the position of the pressure device and achieve a more accurate correction effect.

[0029] In this embodiment, both the first mounting plate 23 and the second mounting plate 32 are provided with a buffer layer to protect the surface of the flange 4 from damage.

[0030] This embodiment utilizes a dynamic pressure mechanism and a static pressure mechanism to correct the large-diameter flange 4. Its structure is simple, operation is convenient, and the correction effect is significant, effectively improving the efficiency and accuracy of flange 4 correction. This embodiment employs a design with a first mounting plate 23 and a first reinforcing rib 24, and a second mounting plate 32 and a second reinforcing rib 33, greatly enhancing the overall structural stability and load-bearing capacity.

[0031] The following is an example of a correction process in this embodiment:

[0032] (1) Place the alignment fixture at the long axis of the outer circle of flange 4.

[0033] (2) Apply force to flange 4 using a hydrodynamic cylinder. Apply force initially until the scale reading on the annular plate is 36mm. Then remove the calibration fixture and check the diameter of flange 4. It was found that the diameter did not change significantly.

[0034] (3) When the second force was applied until the scale reading of the ring plate was about 52mm, the calibration fixture was removed and inspected again. It was found that the diameter of flange 4 had increased by about +10mm.

[0035] (4) Based on the change in the diameter of flange 4, continue to adjust the pressure of the hydrodynamic cylinder. Finally, after applying force to about 87mm, remove the calibration fixture and check. The diameter of flange 4 increased by 5mm, achieving the expected calibration effect.

[0036] The above method can not only effectively correct the diameter of flange 4, but is also simple to operate, safe and reliable, and suitable for various occasions that require precise correction of the diameter of flange 4.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
