Forming press of the pressure cell type comprising a press stand with two opposing pressure absorbing elements (11, 12) defining between them a working space into which a carrier member, such as a trough (2), for supporting forming tools (62) and workpieces (60) is insertable, a press plate (20) communicating with a pressure medium source, a diaphragm (22) forming together with the press plate an expansible pressure cell, and side pieces (40,41) extending along the side surfaces of the working space and retaining the diaphragm in abutting contact with a sealing ring (23) disposed around the periphery of the diaphragm, said sealing ring in turn abutting against the press plate (20). According to the invention a quicker and simpler diaphragm exchange as compared to prior art constructions is achieved by arranging the side pieces turnable so, that when upwardly swung, their long sides abut against the underside of the diaphragm, and by providing means for moving the unit formed of the upwardly swung side pieces and the diaphragm out of the working space. The invention also includes a method for changing diaphragms in such a forming press. |
