Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe correction, in particular to a stainless steel welded pipe correction device. Background Art

[0002] The main method for correcting steel pipe deformation is manual restoration, which is the most common method. Place the deformed steel pipe on a flat ground, and use your palms to push outward or inward on both sides of the deformed part of the steel pipe until the steel pipe returns to its original shape. If the steel pipe is severely deformed and manual restoration is difficult to solve, heating restoration can be used. First, bake it with fire until the deformed part becomes red hot, then use pliers or other tools to straighten the steel pipe at the deformed part, and quickly cool it with cold water, and the steel pipe will return to its original shape. However, it should be noted that the heating temperature should not be too high to avoid further deformation of the steel pipe. For severe deformation, neither manual nor heating restoration can handle it, and mechanical restoration can be considered. This method requires the use of some professional equipment, such as steel pipe curling machines, steel pipe pressing machines, etc. These equipment can help us restore the deformed steel pipe to its original shape.

[0003] For example, the Chinese patent publication number CN217990482U, "A correction device for high-frequency welded pipes", this utility model relates to the technical field of high-frequency welded pipe correction devices, and discloses a correction device for high-frequency welded pipes, including a main body shell, a correction mechanism is arranged inside the main body shell, a fixing mechanism is arranged at the bottom of the correction mechanism, the correction mechanism includes a first fixing ring, the first fixing ring is fixedly connected to the top of the main body shell, the inner ring of the first fixing ring is fixedly connected to the limiting sleeve, and the first fixed rotating shaft is fixedly connected to the front and rear sides of the main body shell. The correction device for high-frequency welded pipes, through the correction mechanism, reaches the high-frequency welded pipe through the threaded sleeve and moves downward to contact the outer rings of the first correction roller and the second correction roller, and corrects the four sides of the front, back, left and right of the outer ring of the high-frequency welded pipe without dead angles, thereby increasing the quality of the high-frequency welded pipe after correction. At the same time, compared with the existing high-frequency welded pipe correction machine, the device is more miniaturized, which is convenient for the staff to carry and use.

[0004] However, in actual use, when correcting the steel pipe, it is necessary to first insert the steel pipe into the limiting sleeve. Since the limiting sleeve is a fixed setting, it is difficult to insert some severely deformed steel pipes. At the same time, it is not easy to play an effective fixing role after insertion, which is not conducive to the subsequent correction of the steel pipe. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Example 1

[0025] like Figure 1-3As shown, the utility model provides a stainless steel welded pipe correction device, including a base 1, a receiving assembly 2 is arranged above the base 1, the receiving assembly 2 includes a support column 201, the support column 201 is rotatably connected to the top of the base 1, a rotating column is arranged on the base 1 and inserted into the support column 201, a hinge seat 202 is hinged above the support column 201, a collar 203 is fixedly connected above the hinge seat 202, a rotating cylinder 204 is rotatably connected to the inner surface of the collar 203, an annular slide groove is arranged between the rotating cylinder 204 and the collar 203 for rotation, a handle 205 is fixedly connected above the rotating cylinder 204, a bolt 206 is threaded through the top of the collar 203, and the bolt 206 is used for rotation. In order to support the rotating cylinder 204 so that it cannot rotate in the ring 203, the lower end of the bolt 206 is movably fitted with the top of the rotating cylinder 204, and a clamping assembly 3 is provided on the inner surface of the rotating cylinder 204, and the clamping assembly 3 includes a clamping plate 301, and the shape of the clamping plate 301 is arc-shaped. The front side of the clamping plate 301 is rotatably connected to a first threaded rod 302, and the first threaded rod 302 is threadedly penetrated by the rotating cylinder 204. The front side of the clamping plate 301 is fixedly connected to a limiting rod 303, and the limiting rod 303 is movably penetrated by the rotating cylinder 204. There are two groups of clamping assemblies 3, and the two groups of clamping assemblies 3 are symmetrically arranged on the front and back of the inner surface of the rotating cylinder 204, and a sliding assembly 4 is arranged on the left side of the accommodating assembly 2.

[0026] In this embodiment, when the stainless steel welded pipe needs to be corrected, the stainless steel welded pipe is first inserted between the two clamps 301 in the rotating cylinder 204. At this time, the two clamps 301 are driven by rotating the first threaded rod 302 to clamp the stainless steel welded pipe. Then, the support column 201 is rotated on the base 1 and the hinge seat 202 is flipped on the support column 201 to align the other end of the stainless steel welded pipe with the correction component 5 for correction. During correction, the handle 205 drives the rotating cylinder 204 to rotate in the ring 203 to adjust the stainless steel welded pipe so as to facilitate all-round correction. The bolt 206 is rotated to support the rotating cylinder 204 for fixing to prevent the stainless steel welded pipe from rotating during correction, thereby weakening the correction effect.

[0027] Example 2

[0028] like Figure 1-3As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the sliding assembly 4 includes an electric slide rail 401, the electric slide rail 401 is fixedly connected to the top of the base 1, and a sliding seat 402 is slidably connected to the top of the electric slide rail 401.

The correction assembly 5 includes a first U-shaped seat 501, and the first U-shaped seat 501 is fixedly connected to the top of the connecting seat 403. The inner surface of the first U-shaped seat 501 is rotatably connected to the first roller 502, and the first U-shaped seat 5 01 is arranged above the second U-shaped seat 503, and the second roller 504 is rotatably connected to the inner surface of the second U-shaped seat 503, and grooves are arranged on the outer edges of the first roller 502 and the second roller 504 for accommodating the stainless steel welded pipe, and a clamping assembly 6 is arranged between the first U-shaped seat 501 and the second U-shaped seat 503, and the clamping assembly 6 includes a supporting sheet 601, and the number of the supporting sheets 601 is two, and the two supporting sheets 601 are respectively fixedly connected to the front and back sides of the first U-shaped seat 501, and a second screw 602 is rotatably connected above the support sheet 601, and an adjusting sheet 603 is threadedly sleeved on the outer surface of the second screw 602, and the adjusting sheet 603 is fixedly connected to the second U-shaped seat 503.

[0029] In this embodiment, after the stainless steel welded pipe is installed and fixed, the other end of the stainless steel welded pipe is placed between the first roller 502 and the second roller 504. At this time, the second screw 602 is rotated to drive the adjusting plate 603 to descend so that the second U-shaped seat 503 descends. The descent of the second U-shaped seat 503 will cause the second roller 504 to cooperate with the first roller 502 to clamp the stainless steel welded pipe. At this time, the sliding seat 402 is driven to slide by the electric slide rail 401 to drive the connecting seat 403 to slide the first U-shaped seat 501.
