Abstract

"PUNCTURE STAMP SYSTEM FOR TOOLS, BY EXPLOSION", where the barrel is provided forwardly, with a stub-holder and where the posterior stem of the trunnion presents, forwards, a widening, or piston, of guide, being able to slide in one part barrel core elongated, characterized in that the front element or fragment of the trunnion stem has a relatively weak mass with respect to the total mass of the trunnion, that the guide piston has an external frusto-conical shape where the small base is oriented forward cooperating, at the end of the working stroke, with a frusto-conical housing, complementary to yours, housed in the guide-trunnion, which is hollow to receive the rear end of the element, or fragment, in front of the trunnion stem and which is longitudinally grooved to tighten, at the end of the trunnion, thanks to the cooperation between said frustoconical guide piston and the housing of the same complementary shape, on the posterior end of the stump front stem fragment to produce a vigorous braking of this fragment.
