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 90-200mm 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 of the bar. Generally, two rows of straightening rollers are provided, and the number of 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) two-roller straightening, wherein different roller shapes are designed according to different rod diameters, so that the quality requirements of the rods 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.
SUMMERY OF THE UTILITY MODEL
The utility model provides a be applied to roller that 90-200mm diameter rod two roller straightener was used, the utility model discloses a technical scheme as follows:
a roller applied to a two-roller straightener for bars with the diameter of 90-200mm comprises an upper roller and a lower roller;
the upper roller consists of a roller head a, a roller diameter a and a roller body a;
the lower roller consists of a roller head b, a roller diameter b and a roller body b;
the roller body a of the upper roller is concave from two sides to the middle;
the roller body b of the lower roller is convex from two sides to the middle;
the roller body a is of a hollow structure, the roller diameter a is arranged in the center of the roller body a, and the roller diameter a and the roller body a are coaxial;
the roller body b is of a hollow structure, the roller diameter b is arranged in the center of the roller body b, and the roller diameter b and the roller body b are coaxial;
the upper roller and the lower roller are matched and used for straightening the bar with the diameter of 90-200 mm.
The roller applied to the two-roller straightener for the bar with the diameter of 90-200mm has the preferable scheme that the roller body b of the lower roller is 900mm in length, and two sides of the roller body b are provided with R50 rounding;
