Abstract (en)
[origin: EP2937157A1] An object of the present invention is to reduce heat transferred from a plate through a receiving jig to a rotating shaft in a spinning forming device. A spinning forming device (1A) includes: a receiving jig (3) supporting a central portion of a plate (9) to be formed; a rotating shaft (2) to which the receiving jig (3) is attached; a heater (6) configured to heat a transform target portion (91) of the plate (9) by induction heating; and a processing tool (7) configured to press the transform target portion (91) to transform the plate (9). The receiving jig (3) is configured to suppress heat transfer from the plate (9) to rotating shaft (2).
