Abstract
Improved extractor for punching machines, characterized by the incorporation under the body of the punching machine with two side arms or side plates joined by a back plate, in the constitution between them an enclosure or box for the punch where it is protected preventing its manipulation, one of said pins is linked to the aforementioned punching machine by an elastic pressure element and by a vertical pin, while the other is simply embedded in a projection of the aforementioned body and has a protruding handle, so that the pull down with this handle makes unlocking against the elastic element of the pin fitted in the projection, to enable the subsequent rotation of the set of pads on the vertical pin of the other pin in order to unchain the punch that will be free for handling.
