Automatic forging and trimming die and method for precisely-forged blade

The invention provides an automatic forging and trimming die and method for precisely-forged blades. The automatic forging and trimming die comprises an upper punch and a lower punch. The shape of a cavity of the upper punch is the same as that of the back side of the precisely-forged blade; a female die is arranged on the upper punch, the female die is nested on the upper punch, the female die moves up and down along the upper punch, and the hole shape of the female die is the same as the outer contour of the forge piece; a cavity of the lower punch is the same as the blade basin side of the precision forging blade in shape, a discharging plate is nested on the lower punch and moves up and down along the lower punch, the hole shape of the discharging plate is the same as the outer contour of the forging piece, and the lower punch is matched with the female die to shear burrs of the forging piece. According to the trimming die for automatic forging production of the precisely-forged blades, burrs and forgings
