ABSTRACT:
The subject piercing die is particularly adapted for piercing a hole in a blank having an open interior and an outer wall defining a closed figure. The piercing is done from the interior of the blank through the wall to the outside of the blank. The piercing die includes a base with a slide movably mounted on the base. A guide is movably connected to the slide to control movement of the slide to a straight line movement. A female die having a blank receptacle for holding the blank is mounted on the base. The female die has a cutting aperture extending through a portion of the female die and intersecting the blank receptacle. A male die is mounted on the slide and is positioned within the blank receptacle for mating with the cutting aperture to cut a hole in a blank positioned in the receptacle. The male die cuts a hole in the blank from the interior of the blank through the outer wall to the outside of the blank. A cam is connectable to the slide for moving the male die toward the female die to engage the blank and to cut the hole in the blank.
