The invention discloses an intelligent manufacturing device for a steel arch frame of a tunnel. The intelligent manufacturing device for the steel arch frame of the tunnel comprises a table surface, wherein support legs are fixedly connected to the two sides of the bottom of the table surface separately; a groove is formed in the table surface; a hydraulic lifting column is fixedly connected to the front surface of the inner cavity of the groove; the top of the hydraulic lifting column penetrates through the groove and extends to the outside of the groove; a connection block is fixedly connected to the front end of the hydraulic lifting column; a rolling wheel is movably connected into the connection block through a pin shaft; the steel arch frame is movably connected to the surface of therolling wheel; and the bottom of the steel arch frame is movably connected with the top of the table surface. According to the intelligent manufacturing device for the steel arch frame of the tunnel,the hydraulic lifting column, the connection block, the rolling wheel, a guide block, a connection plate, a bolt, a motor, a speed reducer and a gear are arranged for cooperative use, so that the intelligent manufacturing device for the steel arch frame of the tunnel is high in bending efficiency, and time-saving and material-saving during bending for steel; and moreover, high machining accuracyis achieved, so that the production cost is lowered, and people are facilitated to use.
