step S2: the motor I (27) is controlled to drive the ball screw nut pair I (26) to rotate, so that the ball screw nut pair I (26) controls the supporting plate (28) to drive the highway guardrail to move to the position right below the cylinder I (22) and the straightening head (24);
step S3: the first cylinder (22) is controlled to move, the turntable (23) and the supporting plate (28) are used for extruding two ends of the highway guardrail, and the second cylinder (33) is controlled to drive the telescopic head (32) to extrude the surface wall of the highway guardrail for straightening;
step S4: after straightening, controlling the supporting plate (28) to drive the highway guardrail to move to the second conveyor belt (6), and controlling the flaw detector (74) to detect the highway guardrail;
step S5: and driving the second conveyor belt (6) to drive the highway guardrail to leave the straightener after the flaw detection of the highway guardrail is completed.
