Blade forging and automatic feeding device and blade rolling and forging method

The invention discloses a blade forging and automatic feeding device which comprises a guide rail in butt joint with a rolling and forging machine. A movable carrier is arranged on the guide rail. Theend, away from the rolling and forging machine, of the guide rail is provided with a feeding part. The movable carrier is provided with a rotating platform. The rotating platform is arranged on the movable carrier through a rotating shaft. Two clamping parts are arranged on the rotating platform and arranged on the two sides of the rotating shaft correspondingly. A movable and rotatable clamp canconduct clamping at the same time at two ends, blade blanks can be sent into the rolling and forging machine continuously and ceaselessly, finished blade products are then taken out and sent out of the rolling and forging machine, the automatic feeding and discharging of the blades are realized, and the blade machining efficiency is improved. The invention further provides a blade rolling and forging method based on the b
