Abstract

In a hydraulic press for forming sheet material, a vertically extending forming cavity is formed in a horizontally extending press stand between a pair of spaced forming pads extending between the inner surfaces of the press stand, and an elastically deformable member extends between the respective end of each of the forming pads for supporting the same. A tool carrier, with an upstanding tool support member having a tool forming depression on each side thereof on which sheet material is formed, is movable into and out of the forming cavity on respective support and guide rails which are engaged by respective support and guide rollers on the tool carrier. The tool carrier divides the forming cavity into a pressure seal on each side of the upstanding tool support member. A pressure medium is injected into each of the pressure cells to form the sheet metal.
