ABSTRACT:
The stationary die of a flat die thread rolling machine is supported on a series of stacked members which may be automatically unclamped, automatically adjusted and then automatically re-clamped to hold the stationary die in a precisely adjusted position relative to a reciprocating die. Fastener blanks from a supply hopper are fed to the dies along a set of parallel rails and are captivated by an upper hold-down rail, there being means for automatically and simultaneously adjusting the elevation of the hopper and the parallel rails and there further being means for independently adjusting the angle and elevation of the hold-down rail. Adjacent blanks in the parallel rails are separated from one another by a catcher which enables a pusher to insert the blanks between the dies in a smooth and trouble-free manner. A die holder for the stationary die is precisely located and locked in the machine but may be easily removed from the machine to facilitate easy and precise installation of the stationary die in the holder.
