The roller type of the utility model meets the requirements of the bar straightening quality; compared with other roll shapes, the straightening capability is stronger, and the roll changing is more convenient.
Description
Technical Field
The utility model belongs to the technical field of two roller straightener, concretely relates to be applied to roller that 40-90mm diameter rod two roller straightener was used.
Background
With the rapid development of industries in various countries, the requirement on the straightness of special steel bar products is higher and higher. The straightening machine is used for straightening bars. The straightening machine extrudes the bar through the straightening roller to change the straightness. Generally, two rows of straightening rollers are provided, and the number of the straightening rollers is different. There are also two-roll straightening machines, which straighten materials of different diameters by means of the angular change of two rolls (concave in the middle, hyperbolic roll). The main types are a pressure straightener, a balance roll straightener, a shoe roll straightener, a rotary reverse bend straightener and the like. And (4) straightening by two rollers, wherein different roller shapes are designed according to different diameters of the bar, so that the quality requirements of the bar with different specifications are met. The straightening effect of the two-roller straightening on the bar is not generated by the plastic bending deformation of a workpiece due to the staggered bending between the adjacent rollers, but generated by the change of the bending curvature inside a pair of roller gaps, so that the roller shape plays a vital role in the bar straightening process.
