Abstract

The device has a press table with a first die half (10), a press ram with a second die half (9), and separate units to close the die halves. At least one of the halves has a separately controlled ram (13,14), which is moved in working direction past the forming contour of the die half. The ram is supported on the supporting part of the die half, an the power-time-ratio of each die half can be regulated. The units to close the die halves are hydraulic or pneumatic ring pistons (5,6) and are positioned to enclose the holder units (1,2) of the die halves.
