[0034] See also Figure 1The present embodiment provides a large diameter steel pipe straightening device, including a base 10, a straightening cylinder 20, a first drive assembly 30, a second drive assembly 40 and an extrusion assembly 50. The straightening cylinder 20 is fixedly mounted on one side of the base 10, and one end of the straightening cylinder 20 is open. The first drive assembly 30, the second drive assembly 40 and the extrusion assembly 50 are all arranged on the inner side of the straightening cylinder 20. The extrusion assembly 50 is distributed axially along the straightening cylinder 20. The second drive assembly 40 is used to drive the extrusion assembly 50 to move radially along the straightening cylinder 20. The first drive assembly 30 is used to drive the extrusion assembly 50 to move in a circular motion.

[0035] When correcting a large diameter steel pipe, the open end of the large diameter steel pipe from the correction cylinder 20 can be placed inside the correction cylinder 20, so that the extrusion assembly 50 passes through the inside of the large diameter steel pipe, and the second drive assembly 40 drives the extrusion assembly 50 to move radially along the correction cylinder 20, so that the extrusion assembly 50 acts on the inner wall of the large diameter steel pipe and squeezes the large diameter steel pipe onto the inner wall of the correction cylinder 20, and the first drive assembly 30 drives the extrusion assembly 50 to move in a circular motion. When the extrusion assembly 50 moves in a circular motion, the large diameter steel pipe can be driven to roll along the inner wall of the correction cylinder 20, and the extrusion assembly 50 can cooperate with the extrusion effect of the extrusion assembly 50 on the inside of the large diameter steel pipe, so that the wall of the large diameter steel pipe can be straightened.

[0036] See also Figure 1 and Figure 2 In one embodiment, the extrusion assembly 50 includes a pressure rod 502, the first driving assembly 30 includes a transmission gear 301, a driving gear 303 and a driving motor, the driving motor is fixedly installed inside the correction cylinder 20, one side of the driving gear 303 is connected to the output end of the driving motor through a driving shaft 304, one side of the transmission gear 301 is rotatably connected to the inner wall of the correction cylinder 20 through a support rod 302, the transmission gear 301 is meshed with the driving gear 303, the second driving assembly 40 is fixedly installed on one side of the transmission gear 301, and the output end of the second driving assembly 40 is connected to the pressure rod 502.

[0037] After the large diameter steel pipe is placed inside the correction cylinder 20, the pressure rod 502 is driven by the second driving component 40 to move radially along the correction cylinder 20, so that the pressure rod 502 acts on the inner wall of the large diameter steel pipe and presses the large diameter steel pipe against the inner wall of the correction cylinder 20, and the driving motor drives the driving gear 303 to rotate, and the meshing action of the driving gear 303 and the transmission gear 301 is utilized to drive the transmission gear 301 to rotate, thereby driving the second driving component 40 and the pressure rod 502 to move in a circle, and the squeezing action of the pressure rod 502 can drive the large diameter steel pipe to roll against the inner wall of the correction cylinder 20, and cooperate with the squeezing action of the pressure rod 502 to realize the straightening treatment of the large diameter steel pipe.

[0038] In one embodiment, the second driving component 40 can be a hydraulic cylinder or a linear motor, which is not limited here.

[0039] See also Figure 1 and Figure 2 In one embodiment, a pressure roller 501 is rotatably arranged on the outside of the pressure rod 502. Through the arrangement of the pressure roller 501, when the pressure rod 502 moves in a circular motion, the pressure roller 502 can roll relative to the inner wall of the large-diameter steel pipe, thereby reducing the friction between the pressure rod 502 and the inner wall of the large-diameter steel pipe, ensuring that the large-diameter steel pipe can smoothly roll along the inner wall of the correction cylinder 20, thereby improving the straightening effect of the large-diameter steel pipe.

[0040] See also Figure 1 In one embodiment, the inner wall of the correction cylinder 20 is further provided with an annularly distributed flexible layer 201. The flexible layer 201 can increase the friction between the large diameter steel pipe and the inner wall of the correction cylinder 20, thereby preventing the large diameter steel pipe and the inner wall of the correction cylinder 20 from sliding relative to each other, thereby further improving the straightening effect of the large diameter steel pipe.

[0041] In one embodiment, the flexible layer 201 may be a rubber layer or a plastic layer, which is not limited here.

[0042] See also Figure 1 and Figure 3 In one embodiment, a material moving assembly 60 is further provided on one side of the base 10 , and the material moving assembly 60 is used to move the large diameter steel pipe into the correction cylinder 20 or move it out from the correction cylinder 20 .

[0043] See also Figure 1 and Figure 3 In one embodiment, the material moving assembly 60 includes a support plate 601, a connecting rod 602, a screw rod 603 and a motor 604. The motor 604 is fixedly mounted on one side of the base 10, and the screw rod 603 is mounted on the output end of the motor 604. The end of the screw rod 603 away from the motor 604 passes through the connecting rod 602 and is threadedly engaged with the connecting rod 602. The support plate 601 is fixedly set at one end of the connecting rod 602.

[0044] During correction, the large diameter steel pipe is placed on one side of the support plate 601, and the motor 604 drives the screw rod 603 to rotate. The screw rod 603 and the connecting rod 602 are threaded together to drive the connecting rod 602 and the support plate 601 to move along the length direction of the screw rod 603. The support plate 601 drives the large diameter steel pipe to move from the open end of the correction cylinder 20 to the inside of the correction cylinder 20. After the correction of the large diameter steel pipe is completed, the motor 604 drives the screw rod 603 to rotate in the opposite direction, and then drives the connecting rod 602 and the support plate 601 to move in the opposite direction to move the large diameter steel pipe out of the correction cylinder 20.

[0045] See also Figure 1 and Figure 3 In one embodiment, the support plate 601 is in an arc-shaped structure, and an arc-shaped groove 202 matched with the support plate 601 is opened on the inner wall of the correction cylinder 20. Through the cooperation between the support plate 601 and the arc-shaped groove 202, when the support plate 601 drives the large-diameter steel pipe to move into the correction cylinder 20, the support plate 601 can be embedded in the arc-shaped groove 202, so that the support plate 601 can form a complete annular surface with the inner wall of the correction cylinder 20, so that the large-diameter steel pipe can roll smoothly along the inner wall of the correction cylinder 20, thereby improving the straightening effect of the large-diameter steel pipe.

[0046] See also Figure 1 and Figure 3 In one embodiment, a guide rod 605 is fixedly provided on one side of the base 10 . The guide rod 605 is offset from and parallel to the screw rod 603 . The guide rod 605 passes through the connecting rod 602 and movably cooperates with the connecting rod 602 .

[0047] The setting of the guide rod 605 can provide a guiding function for the movement of the connecting rod 602, thereby ensuring the smooth movement of the connecting rod 602 and the supporting plate 601.

[0048] In one embodiment, an electric heating plate is also embedded in the inner wall of the correction cylinder 20. Through the setting of the electric heating plate, when the large diameter steel pipe rolls along the inner wall of the correction cylinder 20, the electric heating plate can heat the large diameter steel pipe, thereby enhancing the plasticity of the large diameter steel pipe and cooperating with the extrusion effect of the pressure roller 501, thereby improving the straightening effect of the large diameter steel pipe.

[0049] In an embodiment of the present invention, when correcting a large diameter steel pipe, the open end of the large diameter steel pipe from the correction cylinder 20 can be placed inside the correction cylinder 20, so that the extrusion assembly 50 passes through the inside of the large diameter steel pipe, and the second drive assembly 40 drives the extrusion assembly 50 to move radially along the correction cylinder 20, so that the extrusion assembly 50 acts on the inner wall of the large diameter steel pipe and squeezes the large diameter steel pipe onto the inner wall of the correction cylinder 20, and the first drive assembly 30 drives the extrusion assembly 50 to move in a circular motion. When the extrusion assembly 50 moves in a circular motion, the large diameter steel pipe can be driven to roll along the inner wall of the correction cylinder 20, and the extrusion assembly 50 can cooperate with the extrusion effect of the extrusion assembly 50 on the inside of the large diameter steel pipe, so that the wall of the large diameter steel pipe can be straightened. Compared with the prior art, it can realize automatic correction of large diameter steel pipes, and has the advantages of good correction effect and high correction efficiency.
