Abstract:
PROBLEM TO BE SOLVED: To provide a spinning molding device capable of continuously processing a stepped plate material with a processing tool from a thin part to a thick part.SOLUTION: A spinning molding device 1 includes a receiving tool 22, a rotary shaft 21, a processing tool 4, and a heater 5 for a plate material 9 which has an inward wall surface, facing radially inward, formed on its reverse surface 9b. The receiving tool 22 supports a center part 96 of the plate material 9, and the processing tool 4 presses a top surface 9a of the plate material 9 in a molding area of the plate material 9 across the inward wall surface while moved in a radial direction of the rotary shaft 21. A heater 5 is moved to be positioned on the same circumference with the processing tool 4. The heater 5 includes a first coil part which locally heats the plate material 9 through induction heating while opposed to the reverse surface 9b of the plate material 9, and a second coil part which locally heats the plate material 9 through induction heating while opposed to the inward wall surface of the plate material 9.
