The invention relates to a method for punching bodywork components, notably outer skin components, so that parking aid sensors or headlamp washers can be fitted therein. The invention also relates to a punching machine comprising a bearing element (2) on which a bodywork component is placed, a punch (19) and movement means (5, 10) for moving the punch firstly over a first course to bring it into a position of use, and then over a second course to pierce said component. The punch moves over the second course at a speed that does not exceed 10 mm/s and is slower than the speed of the movement of the punch over the first course. The movement means for moving the punch over the second course comprises a punching ram (11, 21) coupled to a power reduction mechanism. The invention finally relates to use of the machine and to a bodywork component obtained by implementing the method. |
