Abstract
A punch tool for punching a slug from a workpiece. The punch of the punch tool has a reciprocating travel path with a transition region where the punch changes direction. A die plate of the punch tool has an aperture. A support bushing disposed in the aperture of the die plate provides support for the workpiece and has an underside and an opening through which the punch and the slug pass. A nozzle disposed in the aperture of the die plate provides an internal passage for the removal of punch slugs from the tool. The nozzle has a top and a side wall with a hole disposed in the side wall adjacent the transition region of the reciprocating travel path of the punch. The nozzle, the support bushing, and the die plate are integrated to form a flow path delivering a gas flow to the hole in the nozzle. The flow path and the hole direct the gas flow on a slug attached to the punch in the transition region of the reciprocating travel path of the punch to remove the slug from the punch.
