Abstract
For manufacturing a straight strip lamination, a die is provided having at least a main slot punch and a part feature punch. The strip is fed into the die station with a constant slot step distance progression with the slot punch activated to create a plurality of slots. When a part feature is to be punched, the slot punch is deactivated, the part feature punch is activated, and the strip is fed with a new step distance, which is different than the slot distance.
Claims16
A method for manufacturing a straight strip lamination with a press, comprising the steps of:
- providing in the press a die comprising a main slot punch, a separator punch, and a part feature punch;
- activating the main slot and separator punches and deactivating the part feature punch;
- with each stroke of the press, feeding a strip into the die a first same step distance and repeatedly stamping with the main slot punch and the separator punch to create a plurality of slots with punched-out separations therebetween having a desired constant slot distance progression;
- deactivating the main slot punch and the separator punch and activating the part feature punch, and for the next stroke of the press feeding the strip into the die a second step distance different than said first step distance and stamping with the part feature punch so as to create at least one part feature in said strip;
- and
- deactivating the part feature punch and reactivating the slot punch and the separator punch and for the next stroke of the press feeding the strip into the die a third step distance equal to a difference between said first and second step distances, and stamping with the slot and separator punches.
