The utility model is characterized in that two side by side arranged lower leveling rollers (2) are installed on the left transmission shaft (10) and the right transmission shaft (14), and an upper leveling roller (5) is installed on the two lower leveling rollers (2). Wherein, the roll spacing of the two lower leveling rollers (2) and the gauge reduction of the upper leveling roller (5) can be adjusted to straighten different diameters of reinforced bars. The utility model is installed in the horizontal roller system, when straightening, the reinforced bar (3) will go through plastic deformation by adjusting the roll spacing of the two lower leveling rollers (2) and the upper leveling roller (5). Therefore, the autorotation generated by the reinforced bar (3) in the straightening process can be efficiently controlled, meanwhile, the reinforced bar (3) can unify the curvature residual error and reach the equal curvature after going through the plastic deformation, thus ensuring the straightening quality of the reinforced bar.
Description
Technical field
The utility model relates to a kind of steel bar straightener, particularly relates to a kind of equi-curvature scotch device of steel bar straightener.
Background technology
At present, parallel roll-type steel bar straightener is when the aligning reinforcing bar, reinforcing bar in BENDING PROCESS easily the direction along self axis produce rotation, and the original curvature of reinforcing bar often difference is bigger, such one is the deformation plane instability of reinforcing bar, the 2nd, the original curvature disunity of reinforcing bar, and then make the leveling effect of reinforcing bar undesirable.
Summary of the invention
In order to solve the problems referred to above that parallel roll-type steel bar straightener exists, the utility model provides a kind of equi-curvature scotch device of steel bar straightener, during this device aligning in the rotation that prevents reinforcing bar, the original curvature of unified reinforcing bar reaches the purpose of iso-curvature aligning, and then solves the problem that exists in the above-mentioned background technology.
The technical scheme that its technical problem that solves the utility model adopts is: two following smoothing rolls that are arranged side by side and place two upper straightening rolls on the following smoothing roll, wherein the drafts of the roll spacing of two following smoothing rolls and upper straightening roll can be regulated the reinforcing bar of aligning different-diameter to adapt to.When aligning, pass through to regulate the roll spacing of upper straightening roll and two following smoothing rolls, make reinforcing bar that large plastometric set take place in mechanism, the rotation that can produce in the aligning process reinforcing bar is effectively controlled like this, simultaneously, reinforcing bar reaches iso-curvature through unified curvature residual error after the large plastometric set, has guaranteed the straightening quality of reinforcing bar.
The axis of two following smoothing rolls is on a horizontal plane; After upper straightening roll was depressed during work, the line at the following smoothing roll center that the upper straightening roll center is identical with two rollers footpath constituted isosceles triangle, and the axis of reinforcing bar is tangent with the circumference of upper straightening roll identical following aligning roll shape trench bottom formation with two roller footpaths respectively.
The beneficial effects of the utility model are: this mechanism is arranged in the horizontal roller system of steel bar straightener, can prevents the rotation of reinforcing bar in the aligning process effectively, the curvature of unified reinforcing bar is with the iso-curvature aligning of roller system after realizing simultaneously.
