[0022] It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined or described in one drawing, it will not need to be further specifically discussed and described in the description of subsequent drawings.

[0023] To solve the technical problems in the background art, as shown in the Figs. 1-2 The present application provides a technical solution: a metal pipe end correction device, characterized by:

[0024] The fixed seat 1 is the base of the entire correction device, usually made of solid materials such as steel or cast iron to ensure stability during operation. The fixed seat 1 is designed with a mounting surface for mounting the support frame 2 to adapt to the support frame 2. The support frame 2 is fixed to the fixed seat 1, usually by welding or bolt connection. The top of the support frame 2 is designed with a through hole 3. The mounting plate 4 is arranged on the support frame 2, and two mounting plates 4 are arranged on the two sides of the through hole 3. The two mounting plates 4 are connected by a plurality of connecting shafts 5 to ensure synchronization and stability during operation. The connecting shaft 5 can be a high-strength steel bolt or pin. The air cylinder 6 is arranged in the support frame 2, and its telescopic rod passes through the through hole 3 to connect to the hinged piece 7. The air cylinder 6 can be electric or pneumatic, providing power as needed to drive the entire correction process. The connecting plate 8 is symmetrically arranged on both sides of the through hole 3, one end is hinged to the connecting shaft 5, and the other end is connected with the arc plate 9. The connecting plate 8 is provided with a protrusion 10 in the middle, and the protrusion 10 is hinged with a connecting rod 11. The ends of the two connecting rods 11 are hinged to the same hinged point of the hinged piece 7, forming a linkage mechanism. The arc plate 9 is arranged outside the connecting plate 8, and its shape and size are designed to match the support plate 12. The support plate 12 is arranged outside the arc plate 9, and the outer side is a circular arc shape matching the shape of the end of the metal pipe. The support plate 12 is driven by the air cylinder 6 to move the connecting plate 8 through the connecting rod 11, so that the support plate 12 is supported inside the end of the metal pipe for correction.

[0025] It should be noted that the arc-shaped plate 9 is designed as two, respectively located at both ends of the support plate 12, to provide more uniform and stable support. Such a design can ensure that the support plate 12 is uniformly stressed on both sides of the end of the metal circular pipe, avoiding deformation of the circular pipe due to uneven stress. The outer diameter of each arc-shaped plate 9 is adapted to the arc-shaped inner wall of the support plate 12, ensuring that when the arc-shaped plate 9 is supported in the support plate 12 at the end of the metal circular pipe, it can tightly fit the inner wall of the support plate 12, forming a stable support structure. This matching mode helps to improve the accuracy and reliability in the correction process. The two arc-shaped plates 9 are connected to the support plate 12 through the two ends of the connecting plate 8. One end of the connecting plate 8 is hinged to the connecting shaft 5, and the other end is connected to the arc-shaped plate 9 through the protrusion 10 and the connecting rod 11. Such a structure design makes the arc-shaped plate 9 able to move synchronously with the support plate 12 under the drive of the air cylinder 6, realizing uniform correction of the end of the metal circular pipe.

[0026] It should be noted that the support plate 12 has an arc-shaped inner wall, the curvature of which is accurately adapted to the outer diameter of the arc-shaped plate 9. This design allows the arc-shaped plate 9 to be tightly installed inside the support plate 12, forming a structurally stable and functionally effective whole. The arc-shaped inner wall of the support plate 12 not only provides physical cooperation with the arc-shaped plate 9, but also ensures that when the arc-shaped plate 9 is supported in the support plate 12 at the end of the metal circular pipe, it can uniformly distribute the pressure exerted by the support plate 12. This close cooperation helps to improve the stability and uniformity in the correction process.

[0027] It should be noted that the limiting plate 13 is arranged at the bottom end of the support plate 12 to ensure that the metal pipe does not over-insert during the sleeving process, resulting in the end portion being unable to be corrected.

[0028] The support plate 12 is made of high-strength metal material, which has high stability and load-bearing capacity. The limiting plate 13 is arranged at the bottom end of the support plate 12 and is fixed to the support plate 12 by welding or bolt connection. The limiting plate 13 can ensure that the metal pipe does not exceed the range of the limiting plate 13 during the sleeving process. During the sleeving process of the metal pipe, one end of the metal pipe is inserted into the upper end of the support plate 12, and as the metal pipe moves towards the lower part of the support plate 12, the limiting plate 13 limits the movement range of the metal pipe, preventing the metal pipe from over-inserting, thereby ensuring that the end portion of the metal pipe has enough space for correction. The limiting plate 13 can be installed at the bottom end of the support plate 12 by welding, bolt connection or other fixing methods. When installed, it should be ensured that the limiting plate 13 tightly fits the bottom end of the support plate 12 to provide stable support.

[0029] It should be noted that the limiting plate 13 is designed as an arc-shaped plane, the arc-shaped design makes the inner wall of the limiting plate 13 better adapt to the shape of the outer side wall of the support plate 12; the plane design ensures that the contact between the end portion of the metal circular pipe and the limiting plate 13 is smoother during the sleeving process of the metal circular pipe, reducing friction and wear. The inner side wall of the limiting plate 13 is accurately adapted to the outer side wall of the support plate 12.

[0030] It is worth noting that the limiting plate 13 and the supporting plate 12 are manufactured by an integrated forming process, which can improve the stability and integrity of the structure, reduce errors and additional fixing requirements in the assembly process. Integrated forming can be achieved by various metal processing techniques, such as stamping, casting or machining, etc. In the stamping process, a special mold can be designed to form the supporting plate 12 and the limiting plate 13 by one-time stamping, ensuring the accurate matching and connection of the two.

[0031] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
