Abstract:
The invention relates to a jaw pair for punching out holes or recesses, preferably in sheet metal parts, the jaw pair being connectable to a device (23) to be operated preferably hydraulically and being designed, for example, as a pivoting jaw pair, wherein a punch (8) is formed on one jaw and a punching opening (6) is formed on the other jaw. To provide an advantageous jaw pair for punching out holes or recesses, preferably in sheet metal parts, it is proposed that a stripper part (10) which is situated outside of an outer contour of the punch (8) in the punching direction is formed in the jaw having the punch (8) and is movable in relation to the punch (8).
