Deep drawing with presses

Description

Various types of presses are used for the deep drawing of sheet metal, including double-acting presses with mechanical or hydraulic drive.

Mechanical drive

In the case of mechanical presses the blankholder is held by a knuckle-joint system. The drawing process is executed by a multi-link drive. To the extent to which the blankholder and drawing ram are driven by one main shaft, both systems operate in a fixed geometric relationship to one another.

Hydraulic drive

In the case of hydraulic presses the blankholder has several, individually controlled blankholder cylinders. The drawing ram can execute the drawing process independently of the blankholder.
