Abstract
The invention discloses a tooth groove type rebar straightening mechanism which comprises a support and a tooth groove adjusting and pressing device. The tooth groove adjusting and pressing device is mounted on the support. The tooth groove adjusting and pressing device comprises at least two tooth groove wheels located on the two sides of a rebar respectively, and the tooth groove wheels are provided with convex teeth. The tooth groove wheels rotate synchronously, so that three adjacent convex teeth squeeze and straighten the rebar from three contacts distributed on the two sides of the rebar. The tooth groove type rebar straightening mechanism can well eliminate stress at a bend of the rebar and can squeeze and straighten a rebar which is subjected to severe universal twisting, and the straightening effect is good; meanwhile, when the tooth groove type rebar straightening mechanism is adopted to straighten the rebar, due to the fact that the tooth groove wheels straighten the rebar during synchronous rolling, the generated vibration is small; the rebar conveying speed is not affected, and the rebar machining is facilitated.
Description
Technical field
The present invention relates to steel bar meter field, particularly a kind of Alveolus type bar straightening mechanism.
Background technology
The dish type reinforcing bar that steel mill first produces by reinforcement component that current architectural engineering uses usually by straightening severing, then bends to required form and could apply.Traditional bar straightening method carries out traction stretching to reinforcing bar to make it straighten, but, excessive stretching easily damages bar construction, bar diameter is caused to diminish, bearing capacity reduces, the reinforcing bar of damage is applied in architectural engineering easily accidents caused, and therefore, China specifies that the reinforcing bar of architectural engineering can not adopt the mode of stretching to carry out straightening.The principle of existing bar straightening is the stress eliminated by extruding on reinforcing bar, reinforcing bar is straightened, most normal method adopts multiple roller to carry out roll extrusion to reinforcing bar from different directions, the method can eliminate less the bending of curvature, but well cannot eliminate larger the bending of curvature, the reinforcing bar more serious to bending situation is difficult to its straightening work competent.Publication number is that the Chinese utility model patent of CN203944762U discloses the box-like bar straightener of a kind of Novel pressure, and specifically disclose the bar straightening mechanism adopting palm briquetting pressing reinforcing bar to make it straighten, this laminated type bar straightener can obtain good straightening effect to the bending of the overwhelming majority of reinforcing bar, but there is the weak points such as vibrations are large, reinforcing bar transporting velocity is limited in this laminated type bar straightener, still haves much room for improvement.
