Abstract
A spinning thickening forming method is a method of, while rotating a plate including a center portion fixed to a fixing jig, increasing a thickness of a peripheral portion of the plate. Specifically, while locally heating the peripheral portion of the plate such that at least a portion of the plate which is adjacent to the fixing jig maintains stiffness, a forming roller is pressed against the peripheral portion of the plate to compress the peripheral portion in at least a direction perpendicular to a thickness direction of the peripheral portion.
Claims8
A spinning thickening forming method of, while rotating a plate including a center portion fixed to a fixing jig, increasing a thickness of a peripheral portion of the plate, the method comprising
- while locally heating the peripheral portion of the plate such that at least a portion of the plate which is adjacent to the fixing jig maintains stiffness, pressing a forming roller against the peripheral portion of the plate to compress the peripheral portion in at least a direction perpendicular to a thickness direction of the peripheral portion and thereby increase a thickness of a peripheral portion at a position away from the fixing jig.
A spinning thickening forming apparatus comprising:
- a fixing jig to which a center portion of a plate is fixed;
- a rotating shaft to which the fixing jig is attached;
- a heater configured to locally heat a peripheral portion of the plate;
- and
- a forming roller configured to be pressed against the heated peripheral portion of the plate in a pressing direction inclined relative to a direction perpendicular to a thickness direction of the peripheral portion, to compress the peripheral portion in at least a direction perpendicular to the thickness direction of the peripheral portion, wherein
- the forming roller includes:
- a cylindrical pressing surface extending in a rotation axis direction of the forming roller;
- and
- a guide surface rising from one of end portions of the pressing surface so as to form an obtuse angle together with the pressing surface, the one of the end portions being opposite to the other end portion located at a side toward which the pressing direction is inclined.
