The gradual change groove that described reshaping device is just being taken turns recessed shaping is provided with at least two tandem pinch rollers, and the contact point summit triangular in shape of recessed shaping wheel and any two pinch rollers and reinforcing bar distributes.
The gradual change groove that concavo-convex seamless formula automatic straightening of the present utility model utilizes recessed shaping to take turns matches with pinch roller and carries out straightening to reinforcing bar, reinforcing bar from gradual change groove through out-of-date, multiple pinch roller exerts a force from top pressure to reinforcing bar, recessed shaping wheel and any two pinch rollers carry out force extruding from reinforcing bar both sides to reinforcing bar, point of application summit triangular in shape distribution, the stress making it bending that this segment length of reinforcing bar exists can be eliminated, reinforcing bar is straightened; Meanwhile, gradual change groove dual-side limits reinforcing bar, makes the Multi-point force application that reinforcing bar is subject to from pinch roller and gradual change cell wall, carries out straightening shaping to reinforcing bar multiple directions simultaneously.
As the further improvement of technique scheme, the diameter of described pinch roller is less than the diameter of recessed shaping wheel.When the diameter of pinch roller is less, the longitudinal separation between three shaping wheels can be shortened, larger the bending of curvature in reinforcing bar short distance can be eliminated, make the better effects if of extruding straightening.
As the further improvement of technique scheme, described pinch roller is arranged on spring support, is provided with pinch roller is pushed to the stage clip that recessed shaping takes turns between described spring support and mounting bracket.
As the further improvement of technique scheme, described recessed shaping wheel is provided with some gradual change grooves, described gradual change groove is all provided with corresponding pinch roller, many reinforcing bars can be processed simultaneously, raise the efficiency.
As the further improvement of technique scheme, described reshaping device is provided with several, and reshaping device carries out straightening from multiple directions to reinforcing bar, can reinforcing bar that effectively the universal distortion of straightening is serious.
As the further improvement of technique scheme, after described reshaping device, be connected with Scissoring device, carry out cutting after bar straightening at once, make the function of this machine more perfect.
As the further improvement of technique scheme, between described reshaping device and Scissoring device, be provided with directed material guide device.
As the further improvement of technique scheme, between described reshaping device and Scissoring device, be provided with scale metering device, be convenient to carry out scale cutting to reinforcing bar.
As the further improvement of technique scheme, before described reshaping device, be provided with the importing materials device carrying out carrying for importing reinforcing rod.
The beneficial effects of the utility model are:
Contrast prior art, concavo-convex seamless formula automatic straightening of the present utility model utilizes recessed shaping wheel and pinch roller to work in coordination to carry out straightening to reinforcing bar, and its structure is simple, and straightening is effective, the internal structure of reinforcing bar can not be damaged in straightening process, ensure that the load performance of reinforcing bar is constant.
