In an hydraulic press, usable as a press for forming composite sheet material, with a press base, several vertical guides extending out of the press base and a cross head slidably arranged on the vertical guides, which cross head is hydraulically clampable to the vertical guides, with a slidable press plate and a press drive, wherein several long stroke hydraulic cylinders are provided for adjusting the cross head and several short stroke hydraulic cylinders create the stroke of the press plate. The vertical guides and the cross head are made with several guide laminations clampable together in order to realize a guide and coupling system at small construction expense.
