ABSTRACT:
A double-blow header particularly suited for producing semitubular rivets is disclosed. The header is provided with three separate adjustments for controlling the position and operation of the extrusion pin, all of which can be adjusted while the machine is operating. A first adjustment determines the rearwardmost position of the extrusion pin and, in turn, adjustably determines the mass of material contained within the shank of the workpiece. A first powered drive adjustably determines the stroke of the extrusion pin during a piercing operation without altering the rearwardmost position thereof. A second powered drive adjustably determines the kickout stroke without altering the final position of kickout. The kickout drive adjustment and the first adjustment are interconnected so that both of them are adjusted in a related manner.
