Detecting device for heating wire quick-bending machine

The utility model relates to a detecting device for a heating wire quick-bending machine. The detecting device is characterized by comprising a rack, wherein a bending head (1) is arranged in front of the panel of the rack; a sensor (3) and a display screen (4) are sequentially arranged below the bending head (1); first wire guiding wheels (7) are symmetrically arranged on the left and the right of the bending head (1) respectively, and second wire guiding wheels (8) are symmetrically arranged on the left and the right of the bending head (1) respectively; two threading bosses (2) are arranged at the front end of the bending head (1); the left end and the right end of the sensor (3) are respectively connected with two input points of the display screen (4) through conducting wires (9). The detecting device for the heating wire quick-bending machine has the advantage that a bending experiment can be efficiently and accurately carried out.
