Abstract
The drawing press according to the invention includes a support structure for supporting a metal sheet holder which is part of a tool and supported on the press frame via the support structure. The metal sheet holder is assigned a plunger with a die tool, whereas the plunger is moved by means of a plunger drive which includes a blocking position. The blocking position is obtained, for example, by a drive which, in the blocking position does not transmit any movement of the drive output to the driving servomotor. This can be achieved, for example, by an eccentric drive in the stretched position thereof. For performing the actual drawing stroke, the stamping tool is vertically movably supported. A carriage is raised or lowered by the press table by means of a table drive. As table drive, preferably a servomotor with a non-linear drive, such as an eccentric drive is used.
