Universal double cut die set

In a cutoff die set including two relatively movable die shoes, and a cutoff blade mounted to one of said die shoes so as to be driven thereby, an improved mounting arrangement for said cutoff blade comprising:

• means for mounting said cutoff blade;
• mounting means for alternatively mounting said cutoff blade in a longitudinally offset position with respect to said one die shoe;
• said mounting arrangement including a clamping plate and a mounting block secured to said one die shoe, said cutoff blade mounted therebetween;
• aligned hole patterns formed in said mounting block and said clamping plate, said patterns each comprising at least two hole series extending transversely to the length of said cutoff blade mounted therein;
• a hole pattern formed in said cutoff blade comprised of a transversely spaced pair of holes and at least one other hole longitudinally spaced on either side of said pair of holes;
• said pair of holes and a respective one of said longitudinally spaced holes aligning said holes in said mounting block and clamping plate pattern in respective longitudinally offset positions of said cutoff blade mounted therein;
• a plurality of screws passing through said aligned holes in said hole pattern in said clamping plate, said mounting block and said cutoff blade;
• whereby said blade may be adapted to cutting different dimensioned workpieces along the direction of said longitudinal axis, and may be resharpened after breakage thereof.
