Press for material shaping, has head piece with plunger moved up and down with respect to table, where head piece is moveable platform of parallel kinematic device, whose stationary platform is fixed in position with respect to table

摘要

The press has a table (105), and a head piece (104) with a plunger that is moved up and down with respect to the table in a pressing direction using a press drive. The head piece is a moveable platform of a parallel kinematic device, and a stationary platform of the parallel kinematic device is fixed in a position with respect to the table. The parallel kinematic device comprises actuators (112, 113) that are oriented parallel to the pressing direction, A guide is provided for binding the head piece with respect to the head, where the guide is oriented parallel to the pressing direction. An independent claim is also included for a method for operating a hydraulic cylinder-piston-unit in a press.
