s4, when people need to straighten steel pipes with different diameters, the upper straightening wheel (45) and the lower straightening wheel (46) with different models need to be replaced, when the steel pipes are replaced, people firstly separate the upper mounting strip (42) and the lower mounting strip (43) to enable the limiting rings (10) on the upper straightening wheel (45) and the lower straightening wheel (46) to be separated from the annular groove (11), then people twist off the bolts on the nuts (12), and then twist off the nuts (12) from the rotating shaft (44), and at the moment, people can take the upper straightening wheel (45) and the lower straightening wheel (46) off from the rotating shaft (44);
s5, people insert the new upper straightening wheel (45) and the new lower straightening wheel (46) into the rotating shaft (44), and insert the limit groove (7) in the insert hole (6) into the limit strip (8) on the rotating shaft (44), so that the upper straightening wheel (45) and the lower straightening wheel (46) can rotate along with the rotating shaft (44), then people screw the nut (12) at one end of the rotating shaft (44) where the thread is arranged, so that the nut (12) extrudes the upper straightening wheel (45) and the lower straightening wheel (46) on the limit disc (9), and prevents the upper straightening wheel (45) and the lower straightening wheel (46) from sliding on the rotating shaft (44), then people fix the nut (12) on the upper straightening wheel (45) and the lower straightening wheel (46) through the bolt, and prevents the nut (12) from loosening, and at this time, the replacement of the upper straightening wheel (45) and the lower straightening wheel (46) is completed, at the moment, people can straighten steel pipes with different diameters.
