PURPOSE:To easily rotate a lot of metallic dies of the deep bosom, by separately providing a driving shaft on the upper and lower frames, respectively, providing a driven shaft connected to a metallic die holder, on the upper and lower turrets, and connecting or disconnecting both the shafts by a clutch. CONSTITUTION:In a state that a driven shaft 42 connected to metallic dies 18, 19 to be rotated has been positioned in a position opposed to a driving shaft 23, a fluid is made to flow in from a port 41. The driving shaft 23 goes forward and meshes a meshing body 36 with a meshing body 51 of the shaft end of a driven shaft 40. When the upper and lower servo-motors 26 are rotated by the same angle, the rotation of the driving shaft 23 is exactly transferred to metallic die holders 20, 21 through the driven shaft 42 and an interlocking shaft 48, and the upper and lower metallic dies 18, 19 are rotated by the same angle. When it has ended to rotate the metallic dies 18, 19 by a desired angle, a fluid is made to flow in from the port 41, a cylinder rod 31 is contacted, the driving shaft 23 is moved backward, and connection of the driving shaft and the driven shaft is released. |
