| 20100313624 | DIE - A die includes a stationary die, a movable die, which is opposed to the stationary die and reciprocatable in a first direction to change a distance between the stationary and movable dies, and a transfer mechanism, which transfers a workpiece, upon which plastic deformation work is performed between the stationary and movable dies, in a second direction crossing the first direction. The transfer mechanism includes a clamp portion, which clamps/unclamps the workpiece, a synchronizing member, which is engaged with the movable die to reciprocate in synchronization with reciprocation of the movable die, a clamp-unclamp operation converter, which converts reciprocation of the synchronizing member into clamping/unclamping of the workpiece by the clamp portion, and an advance-return operation converter, which converts reciprocation of the synchronizing member into advance-return operation of the clamp portion, whereby the clamp portion advances the workpiece in the second direction and is returned after advancement of the workpiece. | 12-16-2010 |
