Abstract (en)
[origin: EP3222369A1] A hydroforming press with open die and integrated deep-drawing, based on the principle of applying hydrostatic pressure for creating a permanent deformation on a sheet metal, which employs an open die that defines, in a plan view, the outer perimeter of the final part, and allows for a permanent bulging to be formed in the same, while making it possible to incorporate a deep-drawing process prior to the hydroforming process in order to integrate the tab parallel to the hydroforming direction. The open die is located on a horizontal plane inside the press and a plurality of hydraulic cylinders (6) operate on it, of which at least two of them also operate as actuator cylinders, in charge of lowering the die onto the part (1) to be shaped, while all of them come into operation, moving and pressing the female portion (3) of the die against the sheet metal (1) placed on the male portion (2) of the die, before applying the hydroforming hydraulic pressure, operating in the opposite direction, thereon.
