[0031] Working principle: When the equipment is used, the position of the upper straightening wheel 24 is adjusted according to the size of the steel rod. First, the turntable 21 is rotated, and the turntable 21 drives the threaded rod 22 to rotate. At this time, the shaft frame 23 starts to move, and the movement of the shaft frame 23 drives the movement of the upper straightening wheel 24. After adjustment, the steel pipe enters the straightening box 4 through the entrance groove. At this time, the motor 61 is started, and the motor 61 drives the rotation of the driving rod 63. The rotating belt 62 of the driving rod 63 starts to move, and the movement of the belt 62 drives the rotation of the driven rod 64. At this time, the lower straightening wheel 25 also starts to rotate. The rotation of the lower straightening wheel 25 enables the steel rod to be automatically transmitted after being straightened. During the use of the device, the mounting frame 3 and the guide tube 7 can be replaced according to the size of the steel rod, which further expands the scope of application of the device and avoids the situation that the steel rod lacks guidance before entering the straightening wheel due to the fact that only the upper and lower straightening wheels 25 are used to cooperate with the straightening when the device is used, resulting in the steel rod being difficult to enter the straightening wheel for straightening.
