ABSTRACT:
A system and method for forming a plurality of bushing plates from a metallic plate having a plurality of sections, each corresponding to a bushing plate, and a plurality of predetermined regions in which nozzles are to be formed. The second side of the metallic plate is essentially free of protrusions in the predetermined regions. A periphery of each of the predetermined regions is supported by a support having a cavity shaped to generally correspond to an exterior surface of the nozzle. A first punch having a conical tip is used to displace a portion of the predetermined region into the cavity to form an indentation in the first side of the metallic plate while maintaining the periphery essentially free of any externally applied holding pressure. A second punch having a shape generally corresponding to an interior surface of the nozzle drives the portion of the predetermined region into the cavity while maintaining the periphery essentially free of any externally applied holding pressure to form the nozzle between the second punch and the cavity. An alignment device, nozzle tip finisher and section separator are also included in the system. Another aspect of the present invention is a method for forming a nozzle in a bushing plate.
