secondly, the upper die moves upwards, in the process, due to the magnetism of the upper die, the punched stator punching sheet and the waste sheets in the stator punching sheet are adsorbed on the lower surface of the upper die and move upwards along with the upper die, meanwhile, the reciprocating pushing mechanism drives the punching sheet blanking conveying groove to move to the position between the upper die and the lower die along the direction of the guide rail towards the upper die, and the punching sheet blanking conveying groove is positioned below the upper die;
after the upper die moves upwards to a certain position, the ejector rod assembly ejects the stator punching sheet and the waste sheet adsorbed on the upper die; so that the stator punching sheets and the waste sheets fall into the punching sheet blanking conveying groove; then, the stator punching sheet and the waste material sheet slide downwards along the punching sheet blanking conveying groove into the sorting blanking groove under the action of self weight, and the waste material sheet automatically falls through the waste material blanking opening after the waste material sheet slides to the position of the waste material blanking opening because the outer diameter of the waste material sheet is smaller than that of the stator punching sheet, and the stator punching sheet continuously slides downwards along the bottom surface of the sorting blanking groove and is output by the output end of the stator sorting blanking groove; therefore, the separation of the stator punching sheet and the waste sheet is automatically realized, the labor intensity is reduced, the labor cost is saved, and the production efficiency of the stator punching sheet is improved.
