Abstract
A hydraulic drawing system for a press is provided for controlling a blank holder. The blank holder can be moved by at least one hydraulic cylinder-piston unit which has at least one pressure chamber. By way of a connection line, the pressure chamber is connected directly with a control block provided for controlling the movements of the at least one cylinder-piston unit. At least one storage element for storing pressure for the at least one cylinder-piston unit is connected by way of a connection line with the control block and, by way of another connection line at least one valve device is connected with the control block. The connection lines extend in each case at least approximately completely within the respective components.
