Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel pipe production, in particular to a pipe roll misalignment corrector. Background Art
[0002] Steel pipe rolling is a common production process used by steel companies to produce steel pipes. Rolling involves using a plate rolling machine to bend the steel sheet into the desired circular tubular shape. The intersections are then welded together using welding equipment to complete the tube. A plate rolling machine uses work rollers to bend the sheet metal into shape. In actual production, improper placement of the steel sheet or adjustment of the rolling machine can result in uneven edges and misaligned intersections, requiring correction before welding.
[0003] The existing correction method involves welding a small steel plate at each end of the coiled pipe intersection, then manually using a crowbar to pry the two plates between them to align the two ends. However, the small steel plates are temporarily welded, and the movement can easily cause them to fly off and injure people or equipment, posing a safety hazard. Furthermore, after correction and repositioning, the small steel plates must be removed, leaving weld scars on the pipe's exterior, affecting the product's surface integrity. Utility Model Content
[0004] The purpose of the utility model is to provide a roll pipe misalignment corrector, which can correct and align the misalignment of the roll pipe without the need to weld small steel plates on the roll pipe, thereby reducing the risk of small steel plates flying off and avoiding residual weld scars.
[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a pipe misalignment corrector, comprising:
[0006] long pole;
[0007] A hook, the hook being slidably connected to the long rod and fixed by a fastener;
[0008] An end block, the end block being arranged at one end of the long rod and having a screw thread;
[0009] An extrusion plate, located between the hook and the end block, sleeved on the long rod and provided with a through hole having a diameter larger than that of the long rod;
[0010] A stud is threadedly connected in the screw port, and an end of the stud away from the extrusion plate is provided with an end structure that is convenient for the crowbar to drive the stud to rotate.
[0011] A further improvement of the present invention is that a sleeve is slidably connected to the long rod, and the hook is arranged on the outer wall of the sleeve.
[0012] A further improvement of the present invention is that a threaded hole is provided on the sleeve, and the fastener is a fastening bolt threadedly connected in the threaded hole, and one end of the fastening bolt can abut against the long rod.
[0013] A further improvement of the present invention is that the terminal structure is a hook.
[0014] A further improvement of the present invention is that the terminal structure and the stud are an integrated structure, and the structure is an eye bolt.
[0015] A further improvement of the present invention is that at least one auxiliary rod is provided on the end block, the auxiliary rod is located on one side of the long rod and its length direction is consistent with the long rod, the extrusion plate is sleeved on the auxiliary rod and is provided with a through hole matching the auxiliary rod.
[0016] A further improvement of the present invention is that an arc rod portion is integrally provided on one end of the auxiliary rod connected to the end block, and the arc rod portion is welded to the end block.
[0017] The beneficial effects of the present invention are:
[0018] The utility model cooperates with the hook and the extrusion plate on the long rod. The hook is clamped with one side of one end of the coiled pipe, and the extrusion plate is abutted with the other side of the other end of the coiled pipe. The coiled pipe is corrected by moving the extrusion plate toward the hook, and the misaligned edges of the coiled pipe can be corrected and aligned. There is no need to weld small steel plates on the coiled pipe, which reduces the risk of the small steel plates flying off and avoids residual weld scars.
[0019] The hook of the utility model is arranged on the sleeve, and the position of the hook can be adjusted by sliding the sleeve on the long rod, so that the hook can be applied to coiled tubes of different lengths and has a wide range of applications.
[0020] The utility model provides an end structure at one end of the stud which is convenient for the crowbar to drive the stud to rotate. When in use, the stud is driven to rotate by the crowbar to correct the rolled pipe, which is more labor-saving than directly using a crowbar to pull it in the prior art.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example
[0025] Combine Figures 1 and 2 It can be seen that a pipe misalignment corrector includes:
[0026] Long rod 1;
[0027] Hook 2, hook 2 is slidably connected to the long rod 1 and fixed by a fastener;
[0028] The end block 3 is arranged at one end of the long rod 1 and has a screw thread;
[0029] The extrusion plate 4 is located between the hook 2 and the end block 3, is sleeved on the long rod 1 and is provided with a through hole with a diameter larger than that of the long rod 1;
[0030] The stud 6 is threadedly connected in the screw hole, and one end of the stud 6 away from the extrusion plate 4 is provided with an end structure that is convenient for the crowbar to drive it to rotate. Preferably, the end structure is a hook 9.
[0031] A sleeve 7 is slidably connected to the long rod 1 , and the hook 2 is arranged on the outer wall of the sleeve 7 .
[0032] The sleeve 7 is provided with a threaded hole, and the fastener is a fastening bolt 8 threadedly connected in the threaded hole, and one end of the fastening bolt 8 can abut against the long rod 1. Preferably, two fastening bolts 8 are provided on the sleeve 7 to further improve the stability of the fixation.
[0033] Optionally, the end structure and the stud 6 are an integrated structure, which is an eye bolt. The eye bolt is a common bolt in the prior art and can be purchased directly, reducing overall costs.
[0034] The end block 3 is also provided with at least one auxiliary rod 10, which is located on one side of the long rod 1 and has the same length as the long rod 1. The extrusion plate 4 is sleeved on the auxiliary rod 10 and has a through hole that matches the auxiliary rod 10. The auxiliary rod 10 supports the extrusion plate 4, dispersing the pressure applied to the long rod 1 and improving the stability of the extrusion plate 4 during correction.
[0035] The auxiliary rod 10 is integrally provided with an arc rod portion 11 on one end connected to the end block 3, and the arc rod portion 11 is welded to the end block 3.

[0036] The working principle of the roll pipe misalignment corrector provided by the utility model is as follows: when in use, the long rod 1 is placed obliquely at the intersection of the roll pipe, and the position of the hook 2 is adjusted so that the hook 2 is engaged with one side of one end of the roll pipe, and the extrusion plate 4 is in contact with the other side of the other end of the roll pipe. At this time, the crowbar cooperates with the end structure to drive the stud 6 to rotate and push the extrusion plate 4, and the distance between the extrusion plate 4 and the hook 2 gradually decreases, thereby correcting and aligning the misaligned roll pipe.
