Description
Technical field
The utility model relates to a kind of straightener of wire rod, particularly a kind of hot rolled ribbed bar straightening machine guide roller.
Background technology
Since the Ministry of Construction, Ministry of Metallurgical Industry have united nineteen ninety-five since the emphasis of issuing the documents applies hot rolled ribbed steel bar (the particularly new III grade reinforcing steel of 400Mpa), hot rolled ribbed steel bar is coiled the vertical rib distortion in uncoiling aligning back, the problem of longitudinal and transverse rib major injury has become building industry and metallurgical industry a great problem, though this difficult problem is not resolved through the several years effort of numerous producer always.
Hot rolled ribbed steel bar is the cross rib that has of a kind of existing common reinforcing bar, again the wire rod of the vertical rib of two projection symmetries is arranged, it is after the roll pressed shaping of axially being rotated along rod iron under 900 ℃ of high temperature, linearlyly go out roll and enter rotating spirality " spinneret ", draw along this pipe and to enclose in the shape of a spiral that shape advances, when changing into screw by rectilinear motion, do reversing of 360 ° on every circle towards a direction, the cooling afterboarding is that hot rolled ribbed steel bar is coiled.Relevant producer adopted several different methods when this reinforcing bar of aligning: will coiling by traditional method of having is placed on the rotating disk, send into rotation frame straightening mechanism after surrounding edge launches and align along coiling, because this method of deploying has kept original the reversing of reinforcing bar, and smoothing roll or aligning piece are done spiral rolling at rebar surface, so the vertical rib in aligning back reverses, longitudinal and transverse rib damage is serious; What have will coil along after the axial expansion of its every circle, sending into fixedly the posture straightening mechanism through the guiding haulage gear aligns, this method of deploying is equivalent to be changed into by rectilinear motion from the reinforcing bar that roll comes out the inverse process of screw, smoothing roll rolls along the reinforcing bar direction of motion at rebar surface, so avoided the damage of longitudinal and transverse rib to a certain extent.But because reinforcing bar is done reversing of 360 ° on every circle towards a direction when changing into screw by rectilinear motion in course of hot rolling, be shaped to every circle when making cooling and reversed 360 ° coiling when according to said method launching, reinforcing bar is except that also existing bigger distorting stress simultaneously, so still there is following deficiency common bending stress:
1, because when design and making guide roller, only consider the mechanical strength of parts in guide roller and the roller, and serve as according to determining the diameter of guide roller: generally when the reinforcing bar of aligning Φ 6-10 millimeter, serve as that to adopt diameter be 100 millimeters guide roller to foundation just with the required mechanical strength of aligning 10 millimeters reinforcing bars of Φ with its mechanical strength; When the reinforcing bar of aligning Φ 10-16 millimeter, serve as to be 150 millimeters guide roller just according to adopting diameter with the required mechanical strength of aligning 16 millimeters reinforcing bars of Φ.The external diameter that is guide roller is generally about 10 times that are aligned bar diameter.Because the external diameter of guide roller is smaller, it is more bent that the curved surface of its working portion just is tending towards, just short with the contact length of vertical rib, contact area is just little, when the steel longitudinal rib of constantly advancing and having a distorting stress by rotating guide roller to reinforcing bar apply bigger anti-torsion with overcome its distorting stress, when correcting its twist, the guide roller working face can cut away indulging rib the horizontal shear force that short vertical rib applies once in a while at reinforcing bar two vertical rib roots.As long as there is one section vertical rib to be cut off, reinforcing bar just can't utilize the vertical rib of himself to advance in all rollers of guide roller and follow-up work step according to the straight path of setting, and can in all rollers of guide roller and follow-up work step, rotate while advancing, and cause the vertical rib of reinforcing bar to twist, longitudinal and transverse rib major injury;
2. because guide roller only applies clamping force to the vertical rib root basic circle of reinforcing bar, damage rebar surface when the clamping force that applies is big easily, the clamping force that applies hour can't clamp reinforcing bar again, exist the reinforcing bar of distorting stress still can in all rollers of guide roller and follow-up work step, rotate, can't apply anti-torsion to reinforcing bar by guide roller its elimination is reversed while advancing;
3,, must preparation work partial shape size different many during the reinforcing bar of aligning plurality of specifications to guide roller because guide roller is an overall structure, and a kind of geomery of guide roller working portion of specification only is applicable to a kind of reinforcing bar of specification; And after local damage appears in the guide roller working portion, must change whole guide roller, thereby influence the quality of production, reduce production efficiency, improve production cost.
Summary of the invention
The utility model purpose provides a kind of guide roller that utilizes its vertical rib guiding when the aligning reinforcing bar.
The technical scheme that realizes the utility model above-mentioned purpose is: the external diameter of guide roller is at least 14 times by the aligning bar diameter.
The further technical scheme of the utility model is: the external diameter of guide roller is 15-150 times by the aligning bar diameter.
The utility model further technical scheme is: the external diameter of guide roller is 20-80 times by the aligning bar diameter.
The working portion of guide roller is the contacted shape in both ends with two sides, root basic circle and the cross rib of steel longitudinal rib.
Guide roller be split, can regulate two roll bodies in gap between the two by governor motion.
Roll body comprises roller sheet and roller plate base, and roller sheet and roller plate base can be splits.
The roller sheet can be inserted by several and form.
The utility model is compared with background technology owing to adopt as above technical scheme, has following beneficial effect:
1, because the guide roller external diameter is bigger, and its working portion curved surface is tending towards more straight, just long with the contact length of vertical rib, promptly the contact area at the both ends of the two sides of working portion curved surface and steel longitudinal rib, root basic circle and cross rib is just big.When guide roller by vertical rib to reinforcing bar apply anti-torsion with overcome its torsion, when correcting its twist, because two guide roller working faces are to act on one section both ends of two sides, root basic circle and the cross rib of long steel longitudinal rib, so this section steel longitudinal rib can be born from the torsion of guide roller and can not be cut off, can be the reinforcing bar guiding continuously, and steel longitudinal rib is advanced in all rollers of guide roller and follow-up work step according to the straight path of setting, to guarantee to align out qualified reinforcing bar;
2, owing to the guide roller while contacts with the both ends of two sides, root basic circle and the cross rib of steel longitudinal rib, and it is imposed enough clamping forces, by guide roller reinforcing bar being applied anti-torsion reverses its elimination, make steel longitudinal rib in all rollers of guide roller and follow-up work step, advance according to the straight path of setting, so avoided vertical rib distortion, longitudinal and transverse rib damage;
3, because the utility model guide roller is two roll bodies of split, be provided with the governor motion of adjustable clearance between two roll bodies, so the utility model guide roller is applicable to the reinforcing bar of plurality of specifications; Each roll body comprises the roller sheet and the roller plate base of split again, and the roller sheet is inserted by several and is formed, thus the utility model guide roller working portion occur only needing to change corresponding inserting after the local damage, thereby guarantee the quality of production, enhance productivity, reduce production costs.
