FIELD: machine building.
SUBSTANCE: workpiece feeding mechanism in a pilger mill comprises a casing (1), an air chamber (2) with an air piston (3), a piston (4), a water chamber (5) with a hydraulic piston (6) fitted by longitudinal shank ends (7) and (8). The hydraulic piston 6 is installed with an annular gap in relation to the internal surface of a cushion boss (9). A rod (4) is coupled with the air piston (3) on one side and with a mandrel head (12) on the other side. The hydraulic piston is fitted by longitudinal shank ends, in its extreme positions they extend beyond the water chamber (5) by the value being by 5% of its stroke less, the hydraulic piston is made as a bush and can freely move along the rod.
EFFECT: reduced dimensions of the feeding mechanism and higher reliability of its operation.
