Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

An open groove 41 is opened in the middle of each positioning frame 4, and a second pressing wheel 8 is rotatably connected to the bottom of each open groove 41. A connecting block 42 is sleeved inside each open groove 41, and a second pressing wheel 8 is also rotatably connected to the bottom inner wall of each connecting block 42. One side of each second pressing wheel 8 is connected to the pipe body. 3 is rotatably connected, a rectangular block 5 is arranged on one side of each positioning frame 4, a bottom side of each rectangular block 5 is fixedly connected to the workbench 1, two rectangular grooves 51 are arranged in the middle of each rectangular block 5, a slider 52 is slidably connected inside each rectangular groove 51, a top side of each slider 52 is fixedly connected to a U-shaped block 6, one side of each two U-shaped blocks 6 is slidably connected to one side of the rectangular block 5, and a first pressing wheel 7 is rotatably connected to the inner wall of one side of each U-shaped block 6, and one side of each first pressing wheel 7 is rotatably connected to the outer wall of the tube body 3.

[0026] During operation, by installing the workbench 1 at the end of the tube body 3 production line, and then passing one end of the produced tube body 3 through the tube body 3, and then starting the condensation box 2, the tube body 3 can be cooled to prevent the tube body 3 from being deformed during the straightening process. When one end of the tube body 3 passes between the two second pressing wheels 8 inside the positioning frame 4, after passing through the two first pressing wheels 7 on the top of the positioning frame 4, the straightening of the tube body 3 can be completed by the mutual extrusion and cooperation between the multiple first pressing wheels 7 and the second pressing wheels 8. When the equipment needs to be adjusted, the distance between the two second pressing wheels 8 is gradually changed by adjusting the position of the connecting block 42 inside the open groove 41, and the two U-shaped blocks 6 on the top of the adjusting positioning frame 4 are moved. The slider 52 fixed at the bottom of the U-shaped block 6 is connected to the inside of the rectangular groove 51, so that the U-shaped block 6 can slide on one side of the rectangular groove 51 to prevent misalignment during the movement. The two U-shaped blocks 6 can slide on the top of the positioning frame 4 at the same time, thereby changing the distance between the two first pressing wheels 7. By adjusting the positions of the first pressing wheel 7 and the second pressing wheel 8, the pipe bodies 3 of different specifications can be straightened. The above method is convenient for adjusting the equipment at work, reduces the time and energy consumed, improves the working efficiency of the equipment, and improves the straightening efficiency of the stainless steel pipe.

[0027] Further, such as Figure 3 As shown, the top of each connection block 42 is rotatably connected to a threaded rod 9, and the middle of each threaded rod 9 is threadedly connected to the top inner wall of the positioning frame 4. One end of each threaded rod 9 is fixedly connected to a rocker 10, and each threaded rod 9 rotates on the inner wall of the positioning frame 4 through the rocker 10, and each connection block 42 slides inside the open groove 41 through the threaded rod 9. The inner walls at both ends of each connection block 42 are slidably connected to a limit rod 43, and both ends of each limit rod 43 are fixedly connected to the inner wall of the open groove 41.

[0028] During operation, the threaded rod 9 is driven to rotate by rotating the rocker 10, so that the threaded rod 9 can move up and down on the top inner wall of the positioning frame 4, and then the bottom end of the threaded rod 9 is connected to the inner wall of the connecting block 42 by rotation, so that when the threaded rod 9 moves, it can drive the connecting block 42 to move inside the opening groove 41. The structure is simple, which is convenient for the staff to operate and improves the efficiency of the structure. The limiting rod 43 can prevent the connecting block 42 from being misaligned during the movement.

The middle of each bidirectional threaded rod 11 is rotatably connected with a limit block 53, and the outer wall of each limit block 53 is fixedly connected with the middle inner wall of the rectangular groove 51. Both sides of the top of the limit block 53 are in contact with one side of the U-shaped block 6, and each two U-shaped blocks 6 are symmetrically arranged on both sides of the limit block 53.

[0030] During operation, the two-way threaded rod 11 is driven to rotate inside the positioning frame 4 by rotating the other rocker 10, and the two ends of the two-way threaded rod 11 are connected to the inner wall of the slider 52 by threads, so that the two sliders 52 can slide symmetrically in the rectangular groove 51, so that the two U-shaped blocks 6 can move symmetrically, which can ensure the stability of the two U-shaped blocks 6 and facilitate the staff to adjust the distance between the two first pressure wheels 7. The limit block 53 can prevent the two U-shaped blocks 6 from colliding, which can improve the service life of the structure.

[0031] Working principle: By installing the workbench 1 at the end of the tube body 3 production line, and then passing one end of the produced tube body 3 through the tube body 3, and then starting the condensation box 2, the tube body 3 can be cooled. When one end of the tube body 3 passes between the two second pressing wheels 8 inside the positioning frame 4, and then passes through the two first pressing wheels 7 at the top of the positioning frame 4. The straightening of the tube body 3 can be completed by the mutual extrusion and cooperation between the multiple first pressing wheels 7 and the second pressing wheels 8. When the equipment needs to be adjusted, the threaded rod 9 is driven to rotate by rotating the rocker 10, so that the threaded rod 9 can move up and down on the top inner wall of the positioning frame 4. Then, the bottom end of the threaded rod 9 is connected to the inner wall of the connecting block 42 by rotation, so that the threaded rod 9 can drive the connecting block 42 to move inside the open groove 41 when moving. By rotating another rocker 10, the bidirectional threaded rod 11 is driven to rotate inside the positioning frame 4.
