The invention discloses an automatic forming device for a belleville spring and a forming method. The automatic forming device for the belleville spring comprises an oil cylinder, an upper forming die, a lower forming die device, a workbench, a feeding groove, an oil cylinder fixing base, a workpiece outlet sliding block, a rotating shaft, a rotating shaft fixing base, a discharging baffle, a driving motor, a vibrator and a programmable controller. The forming method comprises the steps that an annular wafer is placed in the feeding groove; the annular wafer is conveyed into lower forming dies along the feeding groove under the vibration of the vibrator; a piston of the oil cylinder pushes the upper forming die to move downwards and makes contact with the annular wafer and the lower forming dies so as to press the annular wafer into a cone blank; the piston of the oil cylinder drives the upper forming die to move upwards, the air cylinder drives the workpiece outlet sliding block to contract, the driving moto
