Abstract
A reinforcing steel twist preventing mechanism of reinforcing steel straightening machine belongs to an improvement to the reinforcing steel straightening machine. The technical proposal of the utility model comprises three parallel drive deformation rollers, and a lower pressing deformation roller with a pressing adjustment mechanism arranged on the drive deformation roller pressing adjustment mechanism. The top of the upper surface of the middle drive deformation roller should be higher than the top of the upper surface of the side drive deformation roller, so that the straight-line straightening becomes to curve straightening or arc straightening when the reinforcing steel is straightened. The utility model is arranged at the entrance of a reinforcing steel straightening machine, and can effectively control the axial torsion produced during the straightening process for reinforcing steel, and at the same time, the inner stress produced during reinforcing steel rolling process can be eliminated to ensure a good straightening effect for reinforcing steel.
Description
Technical field
The utility model belongs to a kind of improvement to the steel bar straightener structure.
Background technology
Steel bar straightener before the utility model is realized is when the new III level hot rolled ribbed steel bar of aligning, and often easily in the aligning process, reinforcing bar produces axial torsion along the groove direction of distortion roller, and then makes reinforcing bar produce bending, makes leveling effect undesirable.
Technology contents
The purpose of this utility model is to prevent reinforcing steel bar twisting mechanism by what a kind of steel bar straightener was provided, and then has solved the problem that exists in the above-mentioned background technology.
Comprise in the technical solution of the present utility model three be arranged side by side initiatively be out of shape roller, and be arranged at that the band that initiatively is out of shape on the roller depresses guiding mechanism depress the distortion roller.The peak that the center initiatively is out of shape the roller upper surface should be higher than the peak that side initiatively is out of shape the roller upper surface, so that when carrying out bar straightening, the straight line of reinforcing bar aligning becomes the curve aligning or is called the camber line aligning.
The center initiatively is out of shape the peak of roller upper surface and the difference in height of the peak that side initiatively is out of shape the roller upper surface can be 50-100mm.
For realizing technique scheme, can take following technical measures: the radius that described center initiatively is out of shape roller can initiatively be out of shape roller greater than side; Also can initiatively be out of shape under the identical prerequisite of roller radius, what the axle center horizontal level that the center initiatively is out of shape roller was higher than both sides initiatively is out of shape roller.
The described guiding mechanism center that can be arranged at respectively of depressing initiatively is out of shape roller and side and initiatively is out of shape on the upper surface between the roller.
The utility model is arranged at the porch of steel bar straightener, and the axial torsion that can effectively produce in the aligning process reinforcing bar is controlled, and can eliminate the internal stress that reinforcing bar produces simultaneously in the operation of rolling, has guaranteed the leveling effect of reinforcing bar.
Appended drawings is the structural representation of the utility model duty.In the accompanying drawing: side initiatively is out of shape roller 1, center and initiatively is out of shape roller 2, depresses distortion roller 3, depresses guiding mechanism 4, frame 5, reinforcing bar 6.
Embodiment
Below in conjunction with accompanying drawing a kind of embodiment of the present utility model is elaborated:
Two sides initiatively are out of shape roller 1, center and initiatively are out of shape roller 2 and are arranged in order in frame 5 as figure, and radius is identical, and obtain power from steel bar straightener by chain drive respectively.The shaft core position that the center initiatively is out of shape roller is higher than the axle center 60mm that side initiatively is out of shape roller.Distortion roller 3 center that is arranged in respectively of depressing of depressing guiding mechanism 4 having respectively in the known technology initiatively is out of shape roller and side and initiatively is out of shape on the upper surface between the roller.Depress guiding mechanism and make two to depress the distortion roller reinforcing bar is pressed on the upper surface that the center initiatively is out of shape roller, and overcome the internal stress of reversing of reinforcing bar.Frame in this example, initiatively be out of shape roller, depress distortion roller, the structure of depressing guiding mechanism and correlation all identical with known technology.
