A flat bar straightening machine is a mechanical device used to correct the distortion or warping that occurs during the manufacturing process of flat bars. These distortions can arise from factors such as welding, cooling, or improper handling. The primary function of the machine is to apply precise pressure to specific areas of the flat bar, gradually bending it back into a straight form. The machine typically consists of rollers or presses that guide the metal through a series of adjustments, ensuring uniformity and accuracy.
