  • the precise removal to 00186 the desired dimension can be carried out in a program-controlled manner in a 00187 processing machine.
  • 00188 is also advantageous in that a step associated with the stop 00189 edge runs essentially in the vertical direction to 00190 extension of the pliers, but essentially to the plane spanned by the handle leg 00191. 00192 In this context, it is also advantageous 00193 that a further 00194 step edge, set back from the first, runs out in the undercut to an associated 00195 stop. As a result, there is the possibility that the actual stop surface can be designed to be self-supporting 00197. It stands out cleanly. Finally 00198 is suggested that the second step edge ends rounded 00199. This avoids a notch effect. These features 002001 can nevertheless be realized on a front cutter 00201 and are described on such a cutter.

Abstract

L'invention concerne une pince coupante devant (1) présentant deux branches de préhension (4, 5) et deux mâchoires coupantes (2, 3) montées pivotantes autour d'un pivot (9) et s'étendant chaucne à partir d'une zone de paroi (10, 11) formant une surface de travail, lesdites machoîres coupantes (2, 3) s'appliquant sur les surfaces de travail déplaçables mutuellement et se recouvrant, les arêtes de coupe (6, 6') s'étendant sensiblement à angle droit par rapport aux surfaces de travail. En vue d'améliorer la performance de coupe et la stabilité en cours d'emploi, il est prévu, conformément à l'invention, qu'à chaque position d'ouverture de la pince (1), l'une (6') des arêtes de coupe (6, 6') recouvre, dans la projection du sens de coupe, sensiblement une surface de travail portant l'autre arête de coupe (6).
