Principle of operation: The motor is driven by a belt to increase the speed, so that the straightening cylinder rotates at a high speed. The steel bar passing through the straightening cylinder is straightened, and the rust on the surface of the steel bar is removed by the straightening die; the motor is driven by another pair of reduction belts and geared to reduce speed. The box, on the one hand, drives two conveying rollers to pull the steel bar to move forward, and on the other hand drives the crank wheel to move the hammer head up and down. When the steel bar is adjusted to the predetermined length, the hammer head strikes the upper tool post to cut the steel bar. When the cut steel bar falls into the receiving rack, the tool post returns to its original position due to the action of the spring, completing a cycle.
