ABSTRACT:
A device for converting punch changing in punching machines from manual to quick and automatic comprises: a stator element, which can be inserted in a corresponding and conventional seat provided in the machine and supports a plurality of punches which are arranged vertically in a circular pattern and can slide in corresponding hollow seats; a rotor element, which can be rotated by corresponding elements coaxially inside the stator and is eccentrically provided with a pusher which can be aligned, through gradual rotations of the rotor element, so as to be coaxially vertical above each one of the punches; the rotor element can also be moved vertically by an extent inside the stator, in contrast with elastic elements and guided by stem-like elements which are rigidly coupled to the stator element.
