The apparatus has a die that has an opening shape conforming to a planar shape of the element to be formed. An ejector that has a sectional shape conforming to the opening shape of the blanking blade and is located inside the blanking blade. A punch that has a sectional shape conforming to the opening shape of the blanking blade and moves downward into the blanking blade to blank the element together with the blanking blade, and a pusher that is located around the punch and presses the flat plate-like material against the die. | 12-04-2014 |
20140331836 | ROTARY CUTTING APPARATUS AND ROTARY CUTTING METHOD - A rotary cutting apparatus includes a pair of cutting tools each having a cutting blade along a tip end of its outer peripheral portion having a mountain-shaped cross section, and cuts a cylindrical material into pieces with a predetermined width by sandwiching the cylindrical material between the cutting blades so the cutting blades are respectively placed on inner and outer peripheries of the cylindrical material, and relatively rotating and moving the pair of cutting tools along an entire circumference of the cylindrical material. A second imaginary line connecting an axial center of the cylindrical material and an axial center of the inner peripheral-side cutting tool is shifted in a circumferential direction of the cylindrical material about the axial center of the cylindrical material with respect to a first imaginary line connecting the axial center of the cylindrical material and an axial center of the outer peripheral-side cutting tool. | 11-13-2014 |
