Abstract: A bending press for bending metal sheets, the press comprising a moving top panel and a fixed bottom panel, the bottom panel being constituted by a plate having a top portion and a fixed bottom portion defined by two notches that are symmetrically identical about the transverse midplane of the bottom panel, each notch having a top wall and a bottom wall interconnected by a back wall, and also having an opening situated in the corresponding side edge of the plate, the press being characterized in that each notch is fitted with a displacement member interconnecting the free top portion and the fixed bottom portion of the bottom panel so as to cause the top wall of the notch to move towards the bottom wall thereof, thereby modifying the deformation curve of the free top portion of the bottom panel in controlled manner.

Abstract: The present invention relates to a device for adjusting the height of a plurality of tool carriers connected to a top panel of a bending press, each tool carrier having a tool spacer, the adjustment device comprising, for each tool carrier, an adjustment wedge interposed between the square of the top panel and the top face of the tool spacer associated with said wedge. According to the invention, the ends of each wedge include engagement mechanism to enable a wedge associated with a tool spacer firstly to overlap at least part of the top face of an adjacent tool spacer, and secondly to engage reversibly with the wedge associated with said adjacent tool spacer so that the two adjacent tool spacers touch each other, and the square of the top panel is designed to bear against the engagement mechanism.
