Abstract

An apparatus and method are provided for the simultaneous forming of a plurality of shaped articles from plural sheet metal blanks. First and second sheet metal blanks are arranged between upper and lower forming dies, and a nozzle body having a generally diamond-shaped cross-sectional profile, transverse to an insertion direction, is inserted between the sheet metal blanks. When the forming tool is closed, upper and lower sealing surfaces of the nozzle body press the first and second sheet metal blanks, respectively, against sealing beads that are arranged one each within peripheral areas of the upper and lower forming dies. Opposite side edges of the nozzle body converge one toward the other so as to facilitate forming a seal along each of the side edges of the nozzle body. A pressurized fluid is introduced via the nozzle body for forming the sheet metal blanks within a die cavity.
