The invention discloses a flaring and stamping device with a positioning structure. The device comprises a base and two vertical supporting plates arranged on the base, a transverse plate is arrangedat the tops of the vertical supporting plates, a driving motor is arranged on the transverse plate, and a flaring rod connected with a main shaft of the driving motor is fixed to the middle of the bottom surface of the transverse plate. The flaring and stamping device is characterized in that lifting cavities are formed in the top surfaces of the vertical supporting plates correspondingly; liftingcylinders are fixed to the bottom walls of the lifting cavities correspondingly; piston shafts of the lifting cylinders are fixed to the two ends of the bottom surface of the transverse plate correspondingly; a load-bearing plate is arranged between the lower portions of the two vertical supporting plates; two C-shaped positioning warping rods are arranged on the load-bearing plate; a cavity is formed in the center of the top surface of the load-bearing plate; an abutting panel is arranged in the cavity; and buffering springs are fixed between the abutting panel and the bottom wall of the cavity. The flaring and stamping device is reasonable in structure arrangement, the flaring stability and reliability can be guaranteed easily, position deviation can be prevented, the flaring precisioncan be improved easily, the applicability is high, and the practicability is good.
