ABSTRACT:
The present invention relates to a method and apparatus for producing a smooth edge blank from stock material. A blanking die is carried by the movable die shoe and a closely cooperating blanking punch is secured on the fixed die shoe. Spring biassed means is displaceably provided within the blanking die to apply pressure on a sheet of stock located on the punch only over the area to be blanked out from said sheet of stock. A piercing punch may also be provided and extends coaxially through the blanking die and a bore extending through the blanking punch provides a piercing die. The spring biassed means for applying pressure to clamp the stock only over the area to be blanked is a shedder displaceably disposed within the bore of the blanking die. A stripper encircling the blanking punch is provided for removing scrap stock upon completion of the blanking step and a spacer means is disposed to space the blanking die and the stripper apart by a distance exceeding the thickness of the stock.
