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).

1-9. (canceled)
A jaw pair for punching out holes or recesses in a workpiece, the jaw pair being connectable to a device, comprising:
- a first jaw;
- a second jaw pivotally connected to the first jaw;
- a punch formed on the second jaw, the punch formed from a wall having first and second ends and an outer contour extending between the first and second ends, the second end of the punch defining a punch tip;
- a punching opening formed on the first jaw;
- a stripper part mounted on the second jaw, the stripper part surrounding the outer contour of the punch and being moveable relative to the punch;
- a compression spring mounted on said second jaw for biasing the stripper part toward the punching opening, the stripper part moveable relative to the punch to compress the compression spring;
- and
- wherein the first and second jaws are formed differently, the second jaw having an angled shape in a side view.
(canceled)
A jaw pair for punching out holes or recesses in a workpiece, the jaw pair being connectable to a device, comprising:
- a first jaw;
- a second jaw slidably connected to the first jaw;
- a punch formed on the second jaw, the punch formed from a wall having first and second ends and an outer contour extending between the first and second ends, the second end of the punch defining a punch tip;
- a punching opening formed on the first jaw;
- a stripper part mounted on the second jaw, the stripper part surrounding the outer contour of the punch and being moveable relative to the punch;
- and
- a compression spring mounted on said second jaw for biasing the stripper part toward the punching opening, the stripper part moveable relative to the punch to compress the compression spring.
