A SYSTEM FOR COUPLING/DECOUPLING A THREADED TIE-ROD TO/FROM A TIE-ROD SEATING IN A GUN FOR DEFORMING FIXING ELEMENTS, AND A GUN WITH THE SYSTEM

摘要

The system for coupling/decoupling a threaded tie-rod to/from a tie-rod seating in a gun for deforming fixing elements is characterised in that the tie-rod seating (3) comprises: a tubular sleeve (30) which is provided with a front head (30A), enabling transit of the front end (2A) of the threaded tie-rod (2), and a lateral slit (4) which extends longitudinally, enabling transit of the front end (2A) and the rear end (2P) of the threaded tie-rod (2), facilitating insertion of the rear end (2P) of the threaded tie-rod (2) internally of the sleeve (30) and the alignment of the threaded tie-rod (2) with the axis (Y) of the sleeve (30); the front head (30A) and the lateral slit (4) of the sleeve (30) being profiled such as to enable translation (T) and/or inclination (R) of the threaded tie-rod (2) with respect to the axis (Y) of the sleeve (30) during the step of engaging/disengaging of the threaded tie-rod (2) to/from the sleeve (30).
