摘要： A spinning forming apparatus shapes a plate while rotating the plate around a rotational axis. The spinning forming apparatus includes: a holding member to which the plate is attached and which rotates the plate around the rotational axis; a processing tool configured to contact a first main surface of the plate to process and shape the plate; and a heater configured to heat the plate. The heater is arranged at the opposite side of the processing tool across the plate. The heater locally heats a position of a second main surface of the plate opposite to the first main surface, the position being located on a circumference around the rotational axis, the circumference being defined by a position, with which the processing tool contacts, of the plate.

摘要： A spinning forming device according to one aspect, a receiving jig supporting a central portion of a plate to be formed is attached to a rotating shaft, and a transform target portion of the plate is pressed by a processing tool and locally heated by a heater that performs induction heating. The heater includes an electric conducting pipe in which a cooling liquid flows. The electric conducting pipe includes: a coil portion extending in a circumferential direction of the rotating shaft and having a doubled circular-arc shape facing the plate; and a pair of lead portions extending from the coil portion outward in a radial direction of the rotating shaft. Each of the pair of lead portions is retreated father away from the plate than the coil portion at its end portion adjacent to the coil portion.

摘要： A spinning forming method includes a first forming step and a second forming step, in each of which a plate fixed to a main shaft is formed while being rotated. In the first forming step, a processing tool is brought into contact with a first main surface of the plate to form a first level-changing portion extending from the first main surface toward a second main surface. In the second forming step, the processing tool is brought into contact with the second main surface at an outer peripheral side of the first level-changing portion to form a second level-changing portion extending in an opposite direction to the first level-changing portion.

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.
