This article describes a machine for forming heads on input/output (I/O) pins wherein a pneumatically driven punch causes forming of the head. Referring to the drawings, Fig. 1 is a side view of the machine disclosed herein. Figs. 2 through 7 show the successive steps in forming a head on a pin as follows: 1. A precise length of wire is fed into a stationary shank bushing A and movable heading bushing B by a wire feed mechanism (not shown). As the A and B bushing assembly is moved along stationary rail C, a length of wire (pin) is cut off. (Image Omitted) 2. The initial motions of the tooling are to compress the pin with a punch D to fill the cavities of both bushings (Fig. 2). 3.
