In this operation, once again, a single - Action press with a draw cushion is used. Pushing deformation, the blank holding force is transferred via the slide from above & the draw punch force acts from below through the active draw cushion. The punch forms the post by means of its upward movement while the blank holder rests on the die.
The active Counter drawing combines the advantages of static blank holding & the low power usage of double action dies with the advantage of a single - Action die. Admittedly, it is necessary to have a special modification of the dies for performing this operation, since the forces operate in the opposite direction to those of a normal single action deep drawing press with draw cushion. Thus, these dies can not be installed in a normal single - Action press.
