  • Patent number: 4627264
    Abstract: A cam actuated ejector is provided with a shell press having a crankshaft for reciprocating a slide to which die tooling is mounted and having a forming station in which the die tooling forms a part to be ejected. The ejector includes a kicker bar slidably received within a recess in the press and which is in close proximity to and substantially coplanar with a part to be ejected. The kicker bar is positively reciprocated by a cam assembly that is synchronously engaged with the crankshaft, which operates the press slide, such that an end of the kicker bar cyclically moves at a first rate of movement from a first position outside the forming station to an intermediate position wherein the end contacts a part to be ejected.

  • Patent number: 4554814
    Abstract: An air transfer system for a shell press is provided which air conveys a blanked and formed shell from a blanking and forming die station in the shell press to a curling die station in the same shell press. The air transfer system further provides for the blanked and formed part to be air conveyed within the curling die, and after the shell is curled within the die, provides for the curled shell to be air ejected from the curling die for subsequent fluid conveyance therefrom. A guide track extending between the die stations is just slightly wider than the diameter of the shell being conveyed and the fluid conveyance is provided by a hollow tube disposed in the upwardly facing surface of the guide track. A shell is air conveyed within the curling die station when an opening in a sleeve member, which is disposed about the curling die station and connected to a reciprocating blanking slide, becomes aligned with the guide track upon downward motion of the blanking slide.

  • Patent number: 4442691
    Abstract: A double action mechanical press, especially for performing a blanking operation and a forming operation on each cycle thereof, having a first slide and a second slide, wherein the slides have separate strokes. The slides are reciprocated by means of a crankshaft and connecting rod assembly comprising a single crankshaft and a plurality of connecting rods wherein the throws of the crankshaft can be differently dimensioned and angularly offset relative to each other so as to provide different stroke lengths for the slides and to cause one slide to lead the other. A guide bushing assembly is connected to one of the press slides, and a blanking punch is received in the guide bushing for reciprocating movement relative to the bushing along the same direction of reciprocating movement as the slides. A preloaded antifriction bearing is positioned between the punch and bushing assembly, and serves to maintain the proper clearance between the punch and the corresponding cutting edge on the lower die half.
