Abstract
The present invention discloses one kind of equi-curvature rotation retaining mechanism for steel bar straightener; and features that the equi-curvature rotation retaining mechanism includes two side-by-side lower straightening rollers and one upper straightening roller on the lower straightening rollers, and that both the spacing between these two lower straightening rollers and the draught amount of the upper straightening roller may be regulated to adopt steel bars of different diameters. The present invention is installed inside the horizontal roller system of steel bar straightener to make steel bar generate plastic deformation. The present invention can control the rotation of the steel bar during being straightening and reach the equal curvature of the straightened steel bar to ensure the steel bar straightening quality.
Description
Technical field
The present invention relates to a kind of steel bar straightener, particularly relate to a kind of curvature rotation preventive mechanism 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 invention provides a kind of equi-curvature scotch mechanism of steel bar straightener, during this mechanism 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 solution adopted for the present invention to solve the technical problems 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 reinforcing bar outer surface is tangent with the circumference of upper straightening roll identical following aligning roll shape trench bottom formation with two roller footpaths respectively.
The invention has the beneficial effects as follows: 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.

The specific embodiment
Embodiment
Below in conjunction with accompanying drawing present embodiment being done one describes in detail:
Fig. 1 is an embodiment (see figure 1) disclosed by the invention, two identical following smoothing rolls 2 in roller footpath are installed on two power transmission shafts 10,14 of frame 7, smoothing roll 5 is installed in the top of two following smoothing rolls 2, the roller of upper straightening roll 5 footpath is greater than the roller footpath of smoothing roll 2 down, in the type groove 26 of two following smoothing rolls 2 and upper straightening roll 5 indentation 16 arranged all.Axle 14 is installed in the rolling bearing 21 interior rings, and is fixed on the slide block 18 screw-nut body between roll spacing adjusting device 15 and the slide block 18 by end cap 20.Rotation roll spacing adjusting device 15 can make slide block 18 move on guide rail 19.After adjusting is finished, lock by locking device 24.The structure of roll spacing adjusting device 6,1,11 is identical with roll spacing adjusting device 15.Depress adjusting device 4 and contact with the middle part of upper straightening roll axle 28, two ends, upper straightening roll axle 28 bottom are provided with two springs 9, depress locking device 27 is set on the adjusting device 4.
The axis of two following smoothing rolls 2 is on a horizontal plane, after upper straightening roll 5 is depressed, the line at following smoothing roll 2 centers that upper straightening roll 5 centers are identical with two rollers footpath constitutes isosceles triangle, and the outer surface of reinforcing bar 3 is tangent with the circumference of upper straightening roll 5 identical following smoothing roll 2 type grooves 26 bottoms formation with two roller footpaths respectively.
Following smoothing roll 2 is that main drive roller obtains power by sprocket wheel 17 from steel bar straightener.During aligning, plastic deformation takes place in reinforcing bar 3 between three smoothing rolls, and the curvature of unifying reinforcing bar when overcoming the reinforcing bar rotation reaches the purpose of iso-curvature aligning.
