[0024] Working principle: In use, this utility model places the stainless steel pipe to be straightened on the upper end of the front conveyor line 2. When the stainless steel pipe is placed on the upper end of the front conveyor line 2, the front conveyor line 2 is turned on by control. When the front conveyor line 2 is turned on, the stainless steel pipe will be conveyed backward. When the stainless steel pipe is conveyed backward, the limiting plate 6 will limit and guide the stainless steel pipe conveyed backward, so that the stainless steel pipe can be aligned with the front end of the straightening table 1 while being conveyed backward.

[0025] As the stainless steel pipe is conveyed backward, the reduction motor 9 is activated by control. When the reduction motor 9 is activated, it drives the first transmission sprocket 10 to rotate. When the first transmission sprocket 10 rotates, it drives the second transmission sprocket 11 to rotate via chain drive. When the second transmission sprocket 11 rotates, it drives the main transmission shaft 12 to rotate. When the main transmission shaft 12 rotates, it drives the lower transmission shaft 13 to rotate. When the lower transmission shaft 13 rotates, it drives the main transmission gear 15 to rotate. When the main transmission gear 15 rotates, it meshes with and drives the auxiliary transmission gear 16 to rotate. When the auxiliary drive gear 16 rotates, it will mesh with all the main drive gears 15 in sequence to rotate synchronously. When all the main drive gears 15 rotate synchronously, they will drive the lower drive shaft 13 to rotate synchronously. When the lower drive shaft 13 rotates synchronously, it will drive the lower straightening roller 14 to rotate and convey. When the lower straightening roller 14 rotates and conveys, it will cooperate with the upper straightening roller 20 to squeeze and straighten the stainless steel tube. At the same time, by controlling the opening of the rear conveyor line 3, when the rear conveyor line 3 is opened, it will convey the straightened stainless steel tube backward, thereby realizing the function of facilitating the straightening of the stainless steel tube.

[0026] Simultaneously, by controlling the opening of the electric telescopic rod 5, when the electric telescopic rod 5 is opened, it will drive the limiting plate 6 to move linearly outward or inward. When the limiting plate 6 moves linearly outward or inward, it can adjust the limiting distance of the limiting plate 6 on the stainless steel pipe. By controlling the opening of the drive motor 21, when the drive motor 21 is opened, it will drive the transmission worm 22 to rotate. When the transmission worm 22 rotates, it will mesh and drive the transmission worm wheel 23 to rotate. When the transmission worm wheel 23 rotates, it will drive the internal thread transmission tube 24 to rotate. When the internal thread transmission tube 24 rotates, it will cause the threaded connection to rotate. The force generated drives the transmission screw 25 to move up and down. When the transmission screw 25 moves up and down, it drives the slider 18 to move up and down linearly. When the slider 18 moves up and down linearly, it drives the auxiliary transmission shaft 19 to move up and down linearly. When the auxiliary transmission shaft 19 moves up and down linearly, it drives the upper straightening roller 20 to move up and down linearly. When the upper straightening roller 20 moves up and down linearly, it can adjust the distance between the upper straightening roller 20 and the lower straightening roller 14 for squeezing and straightening the stainless steel tube. This allows for the straightening of the stainless steel tube while facilitating the adjustment of the limiting distance and straightening distance.
