Abstract:
A method for punching which comprises the steps of:providing a workpiece proximate a surface of a die plate defining an aperture having a cross-sectional area;punching a slug from the workpiece through the aperture using a punch having a first side, a second side, and a linear reciprocating travel path with a transition point where the punch changes linear direction;directing a gas flow having a velocity through a distribution channel and an orifice defined in a manifold having a substantially planar top surface directly supporting the die plate; andimpinging the gas flow on the slug attached to the punch in a direction perpendicular to the reciprocating travel path of the punch, on the first side of the punch, and adjacent the transition point of the reciprocating travel path of the punch to remove the slug from the punch, wherein the orifice is positioned at the top surface of the manifold adjacent the transition point of the reciprocating travel path of the punch.
