  • Apparatus for precision forming of sheet metal parts
    Patent number: 4922742
    Abstract: A lower die assembly used in a bending machine to form pre-punched three-dimensional structures has a plurality of plungers located within the V-shaped bending slot of the lower die. As the upper die presses against the pre-punched sheet, the sheet is pinched between an upper end surface of the plungers and the rounded end of the upper die so as to maintain the prescribed position of the sheet during bending. The lower die may include a pin stop which cooperates with positioning holes pre-punched in the sheet in order to establish the desired position of the sheet prior to bending.
