TMT Bar Straightening Machine

The straightening effect is not achieved through the cross bending from the rolls to create the plastic deformation of the bar and eventually the straightening condition, but through the curvature variation from a pair of roll bending.

tmt bar straightening machine

Straightening principle:

The working principle of two roll straightening machine is a special form of the theory of cross roll straightening. The straightening effect is not achieved through the cross bending from the rolls to create the plastic deformation of the bar and eventually the straightening condition, but through the curvature variation from a pair of roll bending. The diameter and curvature of the straightening roller are obtained from the experience getting from the computer simulation home and abroad. Its principle is like this: The processing bar moves rotating forwards in the condition of bending, which makes every section of bar material experience tensile and compressive plastic deformation to achieve the purpose of unifying the internal stress of the material. The roll gap must guarantee the bar to be delivered in smoothly, then the Original bending degree is to be unified according to the equal curvature of the waist of the roller during the rotating feeding of bar material, thus all the original bending degree achieve the same level, and at last straighten the bar in the exit side of the roller. This series of straightening machine design uses a vertical two roller structure with the advantage of concise structure, reliable strength, convenient operation, and high efficiency.  The design of the multi - roll gap curve can ensure the straightening of the bar with different diameters and materials. At the same time, the contact area between the roller and the material is ensured to get a reliable roll polishing effect.
