Abstract

The machine includes a support structure (1) defining a circular seat (2) in which a shaft (20) is coaxially rotatable. The shaft (20) has radial passages (21) in which respective hammering tools (22, 23) are slidable. An annular cage (16) is mounted around the shaft (20) and carries a plurality of rotatable rolling members (17) which project radially from the inner surface of the cage (16). These rolling members (17) are bi-conical rollers which can cooperate with the hammering tools (22, 23) to impart to them a radial hammering movement as a result of relative rotation of the shaft (20) and the cage (16). Two annular thrust members (3, 4) with conical inner surfaces (3a, 4a) surround the rolling members (17) and are movable axially in opposite directions so as to exert a radial thrust on the rolling members (17) towards the shaft (20), thus causing a corresponding radial movement of the hammering tools (22, 23) towards each other.
