Abstract
A ball header is disclosed in which the movable die is mounted directly on the machine frame rather than on the reciprocating slide. The position of the movable die is controlled by a cam driven pusher so that the movable die position is dependent of the position of the reciprocating slide. The machine provides a greater portion of the machine cycle for the movement of the transfer from between the dies after the blank is gripped and controlled by dies. The machine further provides a closed or bushing cutter to improve the shearing of the blanks from the wire stock so that the part formed by the machine can be closer to the finished size of the product to reduce the material content and the cost of finishing operations. The accuracy of the positioning of the movable die is also improved by the mounting of the movable die directly on the frame rather than on the reciprocating slide.
