ABSTRACT:
A press device which is reduced in overall height thereof and in deformation of a press frame and can sufficiently support an eccentric load thereto. The press device comprises a press force generating unit disposed in a press frame and including a lid member secured to the press frame, a cross head having a cylinder chamber in which the lid member is fitted for axial sliding movement and having a blank holder at an end face thereof remote from the lid member, and a pressurizing member fitted for axial sliding movement in a portion of the cylinder chamber remote from the lid member. A shaping element is disposed in the press frame in an opposing relationship to the press force generating unit and has a shaping portion in which the pressurizing member is fitted. A guide element is connected to the cross head for guiding the cross head for axial sliding movement, and a cross head actuating device is connected to the cross head for axially moving the cross head under the guidance of the guide element independently of the pressurizing member.
