Abstract:
An indexing system for a die assembly for manufacturing a stack of laminas from sheet stock material in a punch press, said stack having a desired stack height and skew angle, said stock material having a nominal thickness, said indexing system comprising:a first indexing means adapted to be driven by a said punch press for producing a first indexing movement;an input means for entering an input value selected from the desired stack height, skew angle, and nominal stock thickness;a controller for generating a control signal based on said entered input value a second indexing means responsive to said control signal for producing a second indexing movement;a zero velocity gear mesh differential phase adjuster comprising a plurality of interlocking gears and having a first input shaft for receiving said first indexing movement, a second input shaft for receiving said second indexing movement, and an output shaft, and wherein said interlocking gears combine said first and second indexing movements into a combined indexing output movement and transmit said combined indexing output movement to said output shaft; anda rotatable choke barrel for receiving and stacking laminas, said choke barrel rotationally coupled to said output shaft for rotation thereby in accordance with said combined indexing output movement.
