Description
Technical field
The utility model relates to the rotation stop device of reinforcing bar roll leveller, especially a kind of rotation stop device that adopts iso-curvature.
Background technology
At present, parallel roll-type steel bar straightener is in the process of aligning reinforcing bar, the release of reinforcing bar elastic deformation energy and deadweight and distortion produce reasons such as moment of torsion during owing to uncoiling, reinforcing bar is very easily around self axis rotation, and the original curvature difference of reinforcing bar is bigger, the deformation plane of reinforcing bar is uncertain like this, and the original curvature disunity, and the parameter during bar straightening is wayward and leveling effect is undesirable.
The utility model content
In order to overcome reinforcing bar skimble-scamble problem of original curvature around rotation of self axis and reinforcing bar in the aligning process, the utility model provides a kind of roll-type equi-curvature scotch mechanism, it can not only effectively prevent reinforcing bar when aligning around self axis rotation, and can reach the purpose of unified reinforcing bar original curvature.
The technical scheme that the utility model adopted is: a kind of roll-type equi-curvature scotch mechanism, this device comprises be installed on the casing two groups initiatively smoothing roll groups and be arranged on these two groups and initiatively depress the smoothing roll group between the smoothing roll groups, described active smoothing roll group comprises driven roller and the mobile roller free to rotate moving up and down that rotates around fixed axis, the driving shaft of described driven roller links to each other with motor, connects realization by transmission device between the driven roller and rotates synchronously; The described smoothing roll group of depressing comprises slide plate moving up and down and is arranged on the constant smoothing roll free to rotate of two relative positions on the slide plate.
As a kind of optimal way of the present utility model, described mobile roller is fixed on the support skid, and the adjustment nut is set on the described support skid, and this adjustment nut matches with adjustment screw on being arranged on casing.
As a kind of optimal way of the present utility model, on the described slide plate screw box is set, this screw box matches with housing screw on being arranged on casing.
As a kind of optimal way of the present utility model, described transmission device is a chain gear transmission.
As a kind of optimal way of the present utility model, the roller of described smoothing roll, driven roller and mobile roller footpath is identical.
When aligning, two drive rolls pass through the transmission of two equal diameters sprocket wheels, realize Synchronous Transmission.Two rollers of middle depress roller group are done dead axle and are rotated by being fixed on axle on the slide plate, under the cooperation of housing screw and screw box, along with slide plate is done integral body and depressed.Initiatively the top roll of smoothing roll group is also depressed when aligning, makes depress roller group, two drive roll groups form with reinforcing bar and contact at 3.Reinforcing bar forms the arc section of an iso-curvature, and be accompanied by thrust effect between the roller of two drive roll groups that are arranged side by side, effectively the rotation of reinforcing bar is controlled, reinforcing bar reaches iso-curvature through eliminating residual error after the large plastometric set simultaneously, has guaranteed straightening quality.At the reinforcing bar of different-diameter and different original curvatures, the depress roller group is taked different drafts, when the situation of steel-fastening occurring, can deal with problems smoothly to adjusted by making depress roller group and drive roll group top roll.The utility model can be controlled the rotation of reinforcing bar in the aligning process, and the original curvature of having unified reinforcing bar simultaneously is poor, reaches iso-curvature substantially.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made further specific description in detail.
Fig. 1 is the structural representation of roll-type equi-curvature scotch mechanism duty;
Fig. 2 is the A-A cutaway view of roll-type equi-curvature scotch mechanism;
Fig. 3 is the B-B cutaway view of roll-type equi-curvature scotch mechanism;
Fig. 4 is the left view of roll-type equi-curvature scotch mechanism.
The specific embodiment
The roll-type equi-curvature scotch mechanism that the utility model proposed as depicted in figs. 1 and 2, two drive roll groups being made up of driven roller 2 and mobile roller 4 respectively and the depress roller group of being made up of two smoothing rolls 1 are arranged in parallel within a side of casing by the mode of cantilever support.Two drive roll groups equate with the distance of middle depress roller group.Two mobile rollers 4 are fixed on the support skid 5 by axle, and support skid 5 is fixed together by screw with adjusting nut 6, can drive mobile roller 4 along the slideway of forming with casing and do and move up and down.The mobile of slide plate 5 is to drive by the motion of adjusting nut 6 and the screw pair of adjusting screw 7 compositions, and adjusting screw 7 is to drive by bracing frame 8 supports and by servomotor or stepper motor, and it is mobile only to rotate.
In Fig. 1, two smoothing rolls 1 of depress roller group also are fixed on the slide plate 11 by axle, along with the mobile integral body of doing of slide plate 11 is depressed.Slide plate 11 and screw box 9 are fixed together by screw, and the motion of the screw pair of forming by screw box 9 and housing screw 10 drives slide plate and does along the casing slideway and move up and down.Housing screw 10 also is to be supported and driven by servomotor or stepper motor by bracing frame 8, only rotates and does not move.
The axle of the driven roller 2 in drive roll group is gone up input sprocket 13 and a sprocket wheel 12 is installed, and 2 of the driven rollers in another drive roll group are installed between 12, two sprocket wheels of a sprocket wheel and connected by chain, and input sprocket 13 is connected with the output shaft of motor.Like this, output shaft drive sprocket wheel 12 rotations by motor make another sprocket wheel 12 rotate by chain.And, make that the driven roller 2 in two drive roll groups is done the dead axle rotation and by chain gear transmission, realized the constant speed rotation, as shown in Figure 3 on axle because two sprocket wheels 12 are identical.
Casing is knockdown, can for convenience detach and installation.Smoothing roll contacts by groove with reinforcing bar, the reinforcing bar of the corresponding a kind of diameter of a kind of grooved, as shown in Figure 4.
When aligning, two driven rollers 2 are drive roll, and remaining moves roller 4 and smoothing roll 1 is driven voller, and two smoothing rolls 4 are depressed, and compress reinforcing bar 3, and depress roller group integral body is depressed simultaneously.Reinforcing bar 3 and depress roller group, two drive roll groups form at 3 and contact, and can prevent reinforcing bar rotation around self axis in the aligning process effectively, have eliminated the original curvature residual error of reinforcing bar simultaneously to a great extent.
At the reinforcing bar of different-diameter, can use the smoothing roll of different grooves instead.For the different original curvatures of reinforcing bar of the same race, can adopt different drafts to reach the purpose of spline and unified curvature residual error.
When the situation of steel-fastening takes place,, can deal with problems smoothly by adjusting the backward rotation of screw 7 and housing screw 10.
