ROTATIONAL-PLASTICITY FORMING DEVICE

WIPO Patent Application WO/2014/061330

A1

Provided is a rotational-plasticity forming device capable of improving plasticity-forming accuracy. This synchronous rotational structure (S) is equipped with a: a synchronous gear (8) for integrally rotating with a material-support unit (3); a transmission gear (9) positioned so as to engage the synchronous gear (8); an eccentric coupling (10); and a transmission-gear-position-holding mechanism (K) for holding the position of the transmission gear (9) in a state of engagement with the synchronous gear (8). In the eccentric coupling (10), a drive plate (14) is connected concentrically to the transmission gear (9) so as to be integrally rotatable, and the end of a movable shaft (11) penetrating the drive plate (14) is connected concentrically to a roller (4) so as to be integrally rotatable. The eccentric coupling (10) is provided so as to support the movable shaft (11) in parallel with a principal shaft (1) and in a manner such that both ends of the movable shaft (11) are rotatable in bearings (21). A pressing mechanism (D) is provided so as to move the movable shaft (11) along an interaxial perpendicular line (α) which connects the rotational axis (A2) of the movable shaft (11) and the rotational axis (A1) of the principal shaft (1).
