[0002] Currently, uneven thermal stress is generated during the welding process of straight seam welded pipes, which causes the steel pipes to bend and deform. Therefore, straightening mechanisms are needed for cold straightening. Through plastic deformation, these residual stresses can be partially eliminated, improving the dimensional stability of the steel pipes and enhancing their strength.

In the application of the above-mentioned patent's technical solution, the heating plate and straightening structure in the straightening mechanism are not easy to use together, which affects the straightening effect of the straight seam welded pipe. Therefore, in order to better realize the straightening function of straight seam welded pipes, promote the technological progress of the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the straightening mechanism structure in the prior art.

The welded pipe is straightened by the friction between the plurality of straightening wheels 303 and the welded pipe. In the two adjacent straightening components 3, one set of straightening wheels 303 is arranged in a rectangular shape, and the other set of straightening wheels 303 is arranged in a rhombus shape, so as to straighten the welded pipe from multiple directions. Both sides of the vertical plate 301 are integrally formed with two fixing blocks 304, and one end of the fixing block 304 is fixedly connected to the inner wall of one side of the shell 1.

[0019] The top of the housing 1 is fixed with a top plate 4 by bolts, which facilitates the inspection and maintenance of the components inside the housing 1.

[0020] Both ends of the housing 1 are provided with a material feeding assembly 5. The material feeding assembly 5 includes a connecting cylinder 501. The connecting cylinder 501 is fixed to one end of the housing 1 by bolts. One end of the connecting cylinder 501 is provided with an end plate 502.

[0024] The working principle of this embodiment is as follows: In use, firstly, the welded pipe enters the straight seam welded pipe straightening mechanism through the pipe opening 503 of one of the material feeding components 5. Then, the welded pipe passes between the lower guide wheel 504 and the upper guide wheel 505. Then, the motor 9 is started. Through the slow rotation of the motor 9, the lower guide wheel 504 connected to it is rotated. Then, under the action of the meshing of the two gears 6, the upper guide wheel 505 is rotated, thereby making the welded pipe forward. During the conveying process, the ceramic heating coil 202 is activated and the temperature is controlled below 200 degrees. First, the welded pipe passes through the ceramic heating coil 202 to heat the welded pipe. Then, the welded pipe passes through the through-hole 302 and passes between multiple straightening rollers 303. The welded pipe is then straightened by the friction between the multiple straightening rollers 303 and the welded pipe. Next, the welded pipe passes through multiple heating components 2 and multiple straightening components 3 according to the above steps. The straightening wheels 303 of the multiple straightening components 3 are designed in rectangular and rhomboid shapes to straighten the welded pipe from multiple directions. Finally, under the transmission action of the chain 8 and the meshing action of the two gears 6, another set of lower guide wheel 504 and upper guide wheel 505 are driven to rotate, thereby discharging the straightened welded pipe. The straightened welded pipe is discharged from the pipe opening 503 of another set of material feeding components 5.
