ABSTRACT:
Apparatus for piercing an arcuate workpiece includes a frame, an index table rotatably mounted on the frame, the workpiece being mounted to the index table, and piercing apparatus horizontally adjustable on the frame with respect to the index table. The piercing apparatus includes a pair of tool receiving heads each of which can receive either a punch or a die and means for selectively fixing the particular head used to receive the die and for moving the punch receiving head into and out of engagement with the workpiece so that the workpiece can be pierced from either side. Roller means are provided to facilitate changing the tooling and a stock guide is provided which is reversible so that it can be used regardless of which tool receiving head is being used as the die receiving head.
