ABSTRACT:
A fastener forming apparatus produces a fastener of metal having a rod-to-plate connection often found in such applications as an automotive door latch striker. The fastener is formed and assembled in a single operation and with only a rod and a stamped plate for parts. The forming apparatus has a die structure for securing the rod, a base for vertically aligning the rod, a compression pedestal for vertically aligning the plate and a suspended stamping structure. The stamping structure moves from a pre-staged position for loading of the rod and plate to the die structure, to an intermediate position wherein a head is substantially formed unitarily at the end portion of the rod on one side of the plate, and formation of a unitary protrusion is initiated from the same end portion but on an opposite side of the plate. The structure then moves to a formed position completing the formation of the protrusion, clamping the plate between the head and protrusion, and thus firmly attaching the plate to the rod producing the fastener.
