A method for punching bodywork components, in particular a skin in order to install parking-assistance sensors or headlight washers therein. The invention also relates to a punching machine having an anvil for receiving the bodywork component, a punch, and movement means for moving the punch, initially over a first stroke in order to bring it into a utilization position, and then over a second stroke in order to pierce said component. The movement of the punch over the second stroke takes place at a travel speed not exceeding 10 mm/s and less than the travel speed of the punch over the first stroke. The means for moving the punch over the second stroke comprise a punching actuator coupled to a force-multiplication mechanism. Finally, the invention relates to the use of a machine and to a bodywork component obtained by performing the method.
A method for punching bodywork components, in particular a skin in order to install parking-assistance sensors or headlight washers therein, in which method a bodywork component is placed on an anvil associated with a punch that is held at a distance therefrom when in a rest position, and said punch is moved towards said anvil initially over a first stroke in order to bring it close to said bodywork component, and then over a second stroke in order to pierce said bodywork component, the movement of said punch over said second stroke being performed at a travel speed relative to said bodywork component that does not exceed 10 mm/s and that is less than a travel speed of said punch over its first stroke, wherein said punch is moved over said first stroke with the help of movement means, and over said second stroke with the help of a punching actuator coupled to a force-multiplication mechanism, said punching actuator being distinct from said movement means.
A machine for punching bodywork components, in particular a skin in order to install parking-assistance sensors or headlight washers therein, said machine comprising an anvil suitable for receiving a bodywork component, a punch that is held at a distance from said anvil when in a rest position, and means for moving said punch towards said anvil, initially over a first stroke in order to bring it into a utilization position close to said bodywork component, and then over a second stroke in order to pierce said bodywork component, the movement means being designed so that the movement of said punch over said second stroke takes place at a travel speed relative to said bodywork component that does not exceed 10 mm/s and that is less than the travel speed of said punch over first stroke, wherein the means for moving said punch over said first stroke are distinct from the means for moving said punch over said second stroke, and wherein the means for moving said punch over said second stroke comprise a punching actuator coupled to a force-multiplication mechanism.
