Abstract
A hydraulic press with a pressure cell comprises a tray-shaped press plate with a bag-like diaphragm and a forming rubber pad and a press tray for a forming tool and a workpiece. The end wall portions projecting from the mid portions of each of the press plate and from the base of the press tray, provide thickness transitions which define a cavity in the operating position of the press tray. Between the press plate and/or the base of the press tray and the confronting force-absorbing surfaces of the yokes of the press frame of the press, play is provided in a portion above and below, respectively, the thickness transitions. This play allows the high stress levels which would otherwise arise at the thickness transitions to be reduced.
