CONNECTING PIN, PROCESS MACHINE AND METHOD OF MANUFACTURING OF SUCH CONNECTING PIN Russian patent published in 2015 - IPC F16C11/02 B25D11/06 

FIELD: machine building.

SUBSTANCE: invention relates to the connecting pin of the movable hinged mechanism, first of all hinge drive of piston element, to the process machine and to the method of manufacturing of such connecting pin. The connecting pin (150) has longitudinal length and passes in the mainly transverse to it seat hole (174) for connecting link of the hinged mechanism. The pin (150) also has at least at one its end (160) the groove (154) passing along the longitudinal length, the groove is limited by concave bottom (178) if looking from end (160). Besides, the manual process machine is specified, in particular, perforator with actuator, having at least one mechanism of tool axial drive; it contains movement transfer assembly with linking element and piston element with connecting part and piston part with longitudinal axis; at that the linking element of the movement transfer assembly is connected with the piston element in its connecting part by the mentioned connecting pin (150).

EFFECT: creation of connecting pin with minimum possible weight at simultaneous high loading capacity.
