Straightening machine is a device for straightening metal profiles, bars, pipes, wires, etc. It is not complicated or difficult to learn the straight line operation technology by extruding bars, etc., but it must be cautious, because the operation technology is good and bad. It not only affects the quality, but also affects the generation of scratches and indentations. Improper operation is prone to injury accidents. Straightening machine is a device for straightening metal profiles, bars, pipes, wires, etc. The straightening machine changes the straightness by squeezing the bar or the like through the straightening roller. Generally, there are two rows of straightening rollers, and the number varies. There are also two-roll straighteners, which rely on the angle change of the two rolls (concave in the middle, hyperbolic rolls) to straighten materials of different diameters. The main types are pressure straightening machine, balance roll straightening machine, shoe roll straightening machine, rotary reverse bending straightening machine and so on. The principle of the straightening machine: the bending part of the steel is subjected to considerable reverse bending or stretching, so that a certain elastic-plastic deformation occurs in the part. When the external force is removed, the steel undergoes elastic recovery and then becomes straight.
