Abstract
The triple action cam die set has an upper die, lower die and a cam system that works on multiple axes. A feeder delivers tubes sequentially to a loading station from where the tube is moved to a work station where the ends of the tube are cut and then the cut tube is moved to an exit station. The upper die has pairs of first, second and third drivers, each driver having a caming surface thereon. The lower die has a pair of cutter holders with cutters located opposite the ends of the tube when located at the work station. The cutter holders have first, second and third cam surfaces thereon which are sequentially engageable by the cam surfaces provide on the first, second and third drivers when the upper die is cycled.
