    • The invention relates to a press of pressure cell type, which comprises a press chamber in which a diaphragm device is arranged. The diaphragm device comprises a diaphragm which together with a press plate forms a pressure cell and is adapted to exert a forming pressure on a workpiece in the press chamber. The edge area of the diaphragm is placed in an annular diaphragm support. The press of pressure cell type also comprises actuating means which are adapted to actively exert a force on the diaphragm support in the direction of the press plate, the diaphragm support pressing the edge area of the diaphragm against the press plate so that an initial seal is provided between the diaphragm at its edge area and the press plate, which seal is built up when supplying pressure medium to the pressure cell by expansion of the diaphragm. The invention also relates to a diaphragm device, a method for applying a pressing power and a method for exchanging a diaphragm in a press of pressure cell type.
    • 本发明涉及一种压力容器式压力机,其包括压力室,其中设有隔膜装置。 隔膜装置包括隔膜,其与压板一起形成压力池,并且适于在压力室中对工件施加成形压力。 隔膜的边缘区域放置在环形隔膜支架中。 压力容器型的压机还包括致动装置,其适于在压板的方向上主动地在隔膜支撑件上施加力,隔膜支撑件将隔膜的边缘区域压靠在压板上,使得初始密封件 设置在其边缘区域的隔膜和压板之间,当通过隔膜的膨胀向压力池供应压力介质时,该密封件被建立。 本发明还涉及一种隔膜装置,一种施加按压力的方法和一种在压力容器式压力机中更换隔膜的方法。
