Further, described electromagnetic component comprises electromagnet and iron block, and electromagnet is arranged on mounting cover, and iron block is arranged on position corresponding with electromagnet on ring block, and electromagnet is connected with electric cabinet by circuit.By controlling electric cabinet Push And Release, realizing electromagnet and whether producing magnetic, thus effectively control tapered pole whether clamping motor output shaft.
Further, described tapered pole is elastomeric material, is conducive to tapered pole clamping motor output shaft.
Further, described housing and mounting cover are bolted to connection, for convenience detach, are conducive to changing each element in housing.
The invention has the beneficial effects as follows, be provided with baffle plate by body working face, when reinforcing bar completes U-bend song, baffle plate blocks press-bending bearing pin, avoids the rotatory inertia due to press-bending bearing pin that reinforcing bar is continued bending, causes bending effect bad.The thrust produced by Compress Spring promotes tapered pole, and tapered pole coordinates with housing taper face, makes tapered pole to motor output shaft compression fit, realize motor output shaft and rotate drive housing into rotation, housing drives mounting cover to rotate, and mounting cover drives axis of rotation, thus realizes bar bending.When encountering baffle plate; torque sensor sends a signal to electric cabinet; electric cabinet closing electromagnets circuit; electromagnet is made to produce magnetic; iron block moves tapered pole by attraction influence zone and overcomes spring thrust and move up; make tapered pole not at clamping motor output shaft, motor output shaft and rotating shaft are in off-state, thus effectively protect motor.
Because multiple semicircular ring forms multiple annular curved track, need to select different warp rails according to on-the-spot bar bending radius.Threaded rod extended by rotating rotating cylinder or shortens, allowing clamping device enter on above-mentioned selected warp rail, thus realize the bending of different U-shaped reinforcing bar radius.
Accompanying drawing explanation
Fig. 1 is the structural representation selecting the angle-bender of U-shaped bar bending radius provided by the invention;
Fig. 2 is that this can select the structural representation of the angle-bender working face of U-shaped bar bending radius.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
