The power of motor 12 imports straightening mechanism 6 into through V belt 13, makes the rotating cylinder revolution in the straightening mechanism 6.6 straightener rolls 20 are housed on rotating cylinder, and straightener roll 20 axis become 30 °～35 ° layouts with the tube rotaring axis angle, each 3 of every sides, wherein pair of cross positioned opposite.Straightener roll 20 is contained in the wheel carrier 21, and wheel carrier 21 links with regulating screw mandrel 22 by pressing plate 23, by regulating the distance that screw mandrel 22 can be regulated each straightener roll 20 concave surface and tube rotaring axis.Because straightener roll 20 concave surfaces become 30 °～35 ° envelopes to contact with rebar surface, increased the contact length of reinforcing bar and straightener roll 20, thereby reduced the drafts of 20 pairs of reinforcing bars of straightener roll, make straightener roll 20 do an amount of rolling friction at rebar surface, solved reinforcing bar by straightening after, its vertical rib cross rib has certain scuffing problem, rebar surface flow harden problem.
12 preset rollers are housed on preset mechanism 4, and the physical dimension of preset roller is identical with the straightener roll in the straightening mechanism 7.The preset roller divides two groups, every group 6,30 °～35 ° of each preset roller and horizontal axis angles intersect positioned opposite in twos, and two groups of preset roller central planes are mutually 35 °～45 ° positioned opposite, and the preset roller can be regulated distance with horizontal axis by regulating screw mandrel 22.Because preset roller concave surface becomes 30 °～35 ° envelopes to contact with rebar surface, its concave surface and reinforcing bar are done rolling friction, two groups of preset roller central planes are mutually 35 °～45 ° positioned opposite, when having solved reinforcing bar by the preset roller to neutrality, stressed uniformity consistency is pulled in the process of advancing at reinforcing bar, and the preset roller is done 360 ° of circumferential rolling straightening to reinforcing bar, solved the vertical rib not damaged of straightening hot-rolled screw thread reinforcing bar cross rib, again can be by the technical barrier of straightening.
The guide roller that two pairs of orthogonal one-tenth intersecting parallels are arranged is housed on the material guide device 1, and their effect is a reinforcing bar when passing through the intersecting parallels mouth, because reinforcing bar is pulled, the servo-actuated of guide roller all may be done rolling friction with the guide roller at 360 ° of direction reinforcing bars.Avoid the scratch of rebar surface, reduced the tractive resistance of reinforcing bar.
During the straightening reinforcing bar, require by the reinforcing bar head of straightening have hard curved one section cut with scissors or with hand hammer strike straight after, penetrate material guide device 1, send into carry-over pinch rolls E, the E of box for feeding odd 3

1The traction reinforcing bar is by preset mechanism 4, and the high speed rotary through straightening mechanism 6 rotating cylinders repeatedly on the contrary to bending, makes reinforcing bar obtain straightening reinforcing bar.
Reinforcing bar after the straightening enters hopper in the material bearing shelf 8 by cutting off incision tool bore in the structure 19, reinforcing bar heads on scale plate 14 and does displacement to the right, shut-off mechanism 19 drawn in realize that reinforcing bar cuts off automatically below the tup, use the thrust of reinforcing bar simultaneously, by leverage the door of movable angle steel 16 is opened, the reinforcing bar after the cut-out is fallen on the bearing material carriage automatically.Owing to adopt elasticity screw-down 2, carry-over pinch rolls adopt the R pass, and the rotating cylinder in the straightening mechanism 6 the reinforcing bar band can the work trace and circumferentially rotate, thereby the Longitudinal Warping that former material reinforcing bar is caused in rolling take-up process corrects in turning course.Reinforcing bar is vertical distortionless phenomenon after straightening.
