Automatic die replacing mechanism of steel bar bending machine

The invention discloses an automatic die replacing mechanism of a steel bar bending machine. The automatic die replacing mechanism comprises a die library for placing dies; the three-axis truss corresponds to three different directions of an X axis, a Y axis and a Z axis and is erected above the steel bar bending machine and the mold library; the picking manipulator moves along the three-axis truss, an electromagnet used for attracting a mold is rotationally mounted at the lower end of the picking manipulator, and the electromagnet is in driving connection with a servo motor; the visual camera is mounted on the picking manipulator and is aligned to the mold on the electromagnet; and the intelligent control terminal is in control connection with the picking manipulator, the servo motor and the visual camera. According to the automatic die replacing mechanism of the steel bar bending machine, the whole die replacing process can be automatically controlled, full-automatic unmanned control over the whole bending
