    摘要: A method of manufacturing a preliminary formed body includes an ironing step and a thickening step. In the ironing step, a predetermined range of a plate is formed into a tapered shape in such a manner that while rotating the plate, a transform target portion of the plate is locally heated by induction heating, and a processing tool is pressed against the transform target portion. In the thickening step, a peripheral portion that is a distal end of the tapered shape of the plate is expanded inward in such a manner that while rotating the plate, the peripheral portion is locally heated, and a forming roller is pressed against the peripheral portion to push the peripheral portion in a direction orthogonal to a thickness direction of the peripheral portion.

    摘要: Disclosed herein is an apparatus and method for forming a product having an asymmetric cross-section using a ring rolling process. The method of forming a product having an asymmetric cross-section uses a ring rolling process that uses a ring rolling apparatus, the ring rolling apparatus comprising: a main roll pressing a circumferential outer surface of a blank, a pressure roll pressing a circumferential inner surface of the blank, and a pair of axial rolls pressing upper and lower surfaces of the blank, wherein a protrusion provided on the pressure roll comes into contact with a depressed portion formed on the circumferential inner surface of the blank, and as a width of the blank varies, the pressure roll moves in a vertical direction.

    摘要: A ring mill apparatus and method utilizes at least one hydraulic or other direct drive motor to drive a roller in contact with a ring that is to be expanded by the ring mill. The motor may be two opposed radial piston hydraulic motors, to drive an upper king roller, which contacts the outside of the ring, which is inserted between the upper king roller and a lower mandrel roller, which contacts the inside of the ring. The lower mandrel roller is urged upwards against the ring by a ram driven carriage. Two hydraulic or other direct drive motors can be provided in-line with, and directly connected to, the king roller.
