s1) detecting the deformation quantity of the square tube by a video detection device;
s2) the detected square tube is sent into an automatic square tube straightener (1) for primary straightening processing, and the straightening pressing amount of the square tube is controlled according to the deformation amount of the square tube detected by the video detection device;
s3) the lifting seat (1-2) is lowered to a preset height, the upper straightening roller (1-2-1) rotates anticlockwise, the lower straightening roller (1-6-1) rotates clockwise, and the square pipe is fully processed in the automatic square pipe straightener (1);
s4) after the first straightening processing is finished, the square tube is conveyed to a square tube turnover mechanism (2) through a conveying unit, the square tube turnover mechanism (2) clamps the square tube, the square tube is turned over at a preset angle, and the square tube is straightened in the other direction;
s5) conveying the turned square tube to an automatic square tube straightening machine (1), loosening the square tube by using a square tube turning mechanism (2), feeding the turned square tube into the automatic square tube straightening machine (1) for secondary straightening, rotating an upper straightening roller (1-2-1) clockwise, and rotating a lower straightening roller (1-6-1) anticlockwise;
s6), judging whether the square tube is straightened, if so, adjusting the lifting seat (1-2) to an initial position, and transporting the square tube to a stacking unit; if not, return is made to step S1).
