Convenient-to-disassemble shearing device of steel bar truss forming machine

The utility model discloses a convenient-to-disassemble shearing device of a steel bar truss forming machine. The convenient-to-disassemble shearing device comprises a workbench, an oil tank, supporting legs, a hydraulic cylinder and a shearing device body. The four corners of the bottom face of the oil tank are fixedly connected with supporting legs correspondingly. The bottom face of one end of the workbench is fixedly connected with the top face of the oil tank, and the bottom face of the other end of the workbench is symmetrically and fixedly connected with a set of supporting legs. The hydraulic cylinder and the shearing device are fixedly connected to the upper surface of the workbench. The hydraulic cylinder is connected with the power switch through an electric wire. The height of the pressing plate is adjusted by adjusting the length of the electric hydraulic rod, so that a to-be-sheared steel bar at the top end of the steel bar truss is clamped in a groove of the pressing plate, and the groove fixes
