The loading and unloading function and the high-precision alignment function are relatively separated, and a cooperative mechanism for active and centering calibration at the moment of placement is lacked. Therefore, the final positioning accuracy still depends on the repeated positioning accuracy of the mechanical arm, and the small deviation of the die and the blank cannot be adaptively compensated, so that the actual placement position of the blank in the die cavity still fluctuates, and the thickness of the drawn pot is difficult to be ensured to be extremely uniform. Therefore, the feeding and discharging and the fine alignment are still two disjointing steps, and are not a smooth and intelligent cooperative process.
