Description

Technical Field

[0001] The utility model relates to the technical field of pipe roundness correctors, in particular to a roundness corrector used for pipe correction. Background Art

[0002] Prior art, such as the Chinese utility model patent document with publication number CN206066992U, discloses a roundness corrector comprising a first clamping plate, a second clamping plate, a hinge structure and a locking structure; one end of the first clamping plate and one end of the second clamping plate are hinged by the hinge structure, and after hinged connection, the first clamping plate and the second clamping plate form a circle; the other end of the first clamping plate and the other end of the second clamping plate are locked and connected by the locking structure.

[0003] Based on the above, in the prior art, the pipe is rounded using a first and second plywood that, after being hinged, form a circle. A problem with this circular plywood structure is that, because the first and second plywood form a circle, it can only calibrate pipes with a diameter corresponding to that circle and is not suitable for pipes of other calibers, resulting in poor applicability. Furthermore, the roundness corrector forms a perfect circle or a near-perfect circle after tightening. Because plastic pipes have a certain degree of toughness, when the roundness corrector is loosened, the pipe will deform and rebound, making it impossible to achieve true rounding, and further improvement is needed. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a roundness corrector for pipe correction.

[0005] A roundness corrector for pipes designed for this purpose includes a first clamping element and a second clamping element, each of which is provided with an arc-shaped roundness correction plate, the arc-shaped roundness correction plate being in contact with the outer wall of the pipe;

[0006] The first clamping element and the second clamping element are connected with a spacing adjustment component, and the spacing adjustment component is configured to adjust the spacing between the first clamping element and the second clamping element so as to clamp the pipe through two arc-shaped rounding plates to cause the pipe to deform.

[0007] Preferably, one end of the first clamping element and one end of the second clamping element intersect with each other, and the spacing adjustment assembly is connected to the other end of the first clamping element and the other end of the second clamping element respectively.

[0008] Preferably, the spacing adjustment assembly includes a screw and a threaded sleeve, the screw is hinged to the other end of the second clamping element, the threaded sleeve is threadedly connected to the screw, and the threaded sleeve abuts against the other end of the first clamping element.

[0009] Preferably, a matching block is provided at the other end of the first clamping element, and the end surface of the threaded sleeve close to the second clamping element abuts against the matching block.

[0010] Preferably, a positioning groove is provided at the other end of the first clamping element, and the matching block is plugged and assembled in the positioning groove.

[0011] Preferably, the threaded sleeve is connected to a rotating handle.

[0012] Compared with the prior art, the present invention adopts an arc-shaped calibration plate located at the first clamping element and the second clamping element to fit the outer wall of the pipe. Under the action of the spacing adjustment component, the arc-shaped calibration plate can squeeze the pipe to cause the pipe to deform and achieve correction. The present invention adopts an arc-shaped calibration plate, which can fit, extrude and correct pipes of different calibers and has strong applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] See also Figure 1-Figure 3 A roundness corrector for pipe correction includes a first clamping element 10 and a second clamping element 20. Both the first clamping element 10 and the second clamping element 20 are provided with an arc-shaped roundness correction plate 30. The arc-shaped roundness correction plate 30 is in contact with the outer wall of the pipe 50.

[0019] The first clamping element 10 and the second clamping element 20 are connected with a spacing adjustment component 40, and the spacing adjustment component 40 is configured to adjust the spacing between the first clamping element 10 and the second clamping element 20 so as to clamp the pipe 50 through two arc-shaped rounding plates 30 to cause the pipe 50 to deform.

[0020] In the present invention, an arc-shaped calibration plate located between the first clamping element and the second clamping element is fitted with the outer wall of the pipe. Under the action of the spacing adjustment component, the arc-shaped calibration plate can squeeze the pipe to cause the pipe to deform and achieve correction. The present invention adopts an arc-shaped calibration plate, which can fit, extrude and correct pipes of different calibers and has strong applicability.

[0021] Furthermore, the arc-shaped circular alignment plate employed in this invention is arc-shaped. When pressed against the tubing 50, it achieves an interference fit. Upon release, the tubing naturally rebounds, achieving a near-perfect circle. Furthermore, a spacing adjustment assembly is employed, allowing the operator to dynamically adjust the spacing adjustment assembly based on the real-time deformation of the tubing 50 until the calibrated tubing achieves a near-perfect circle.

[0022] See also Figure 1 and Figure 2 One end of the first clamping element 10 and one end of the second clamping element 20 intersect with each other, and the spacing adjustment assembly 40 is connected to the other end of the first clamping element 10 and the other end of the second clamping element 20, respectively. The spacing adjustment assembly tightens the spacing between the two intersecting first and second clamping elements, thereby squeezing the tubing 50 through the arc-shaped rounding plate, deforming the tubing 50 and achieving rounding.

[0023] See also Figure 1 and Figure 2 The spacing adjustment assembly 40 includes a screw 410 and a threaded sleeve 430. The screw 410 is hinged to the other end of the second clamping element 20, the threaded sleeve 430 is threadedly connected to the screw 410, and the threaded sleeve 430 abuts against the other end of the first clamping element 10.

[0024] During roundness calibration, the pipe to be welded is measured using an out-of-roundness ruler to locate the pipe's maximum outer diameter and mark the port location with a marker. The pipe is then assembled with the roundness calibrator, which is then adjusted so that the axis B of the screw 410 is parallel to the pipe's maximum outer diameter A. The threaded sleeve 430 is then tightened, gradually reducing the distance between the first clamping element 10 and the second clamping element 20. During this process, the maximum outer diameter A of the pipe 50 is gradually reduced. Following these adjustments, the fusion fitting to be connected to the pipe 50 is inserted into the socket. Depending on the socketing condition, the threaded sleeve 430 is further adjusted until the fusion fitting and the pipe 50 are properly socketed.

[0025] See also Figure 2The other end of the first clamping element 10 is provided with a mating block 420, and the end surface of the threaded sleeve 430 adjacent to the second clamping element 20 abuts against the mating block 420. The mating block 420 abuts against the threaded sleeve 430 so that when the threaded sleeve 430 is tightened, the first clamping element and the second clamping element are clamped together.

[0026] See also Figure 2 The other end of the first clamping element 10 is provided with a positioning groove 110, and the matching block 420 is plugged and assembled in the positioning groove 110. The positioning groove 110 is provided with an opening at one end facing away from the second clamping element, and the matching block 420 is plugged and assembled in the positioning groove 110 through the opening.

[0027] See also Figure 1 and Figure 2 The threaded sleeve 430 is connected to a rotating handle 440. The function of the rotating handle 440 is to hold the rotating handle 440 to drive the threaded sleeve 430 to rotate.
