Abstract
The stationary die of a thread rolling machine is mounted in a holder which enables the stationary die to be tilted relative to the movable die about an axis which coincides with the upper edge of the thread forming face of the stationary die. The upper edge of the die thus stays stationary when the die is tilted and remains in a fixed position relative to a track which guides fastener blanks between the dies.
Claims4
A holder for the stationary die of a thread rolling machine, said die including a thread forming face having upper and lower edges, said holder comprising a mounting block and an adjustable block suppoted on said mounting block, said die being supported on said adjustable block, said mounting block being formed with a concavely arcuate seat having an axis coinciding with the upper edge of the thread forming face of said die, said adjustable block having a convexly curved surface concentric with said seat and disposed in engagement with said seat, means for securing said adjustable block to said mounting block to hold said surface in engagement with said seat while permitting said surface to slide along said seat, and selectively adjustable means connected between said blocks and operable when adjusted to cause said surface to slide along said seat thereby to tilt the thread forming face of said die without changing the location of the upper edge of said thread forming face.
