Patent number: 10882094Abstract: In a spinning forming method, a plate including a peripheral portion at which a ring-shaped projection is provided is used, the projection projecting in a thickness direction of the plate. Further, while rotating the plate, a transform target portion of the plate is locally heated, and a processing tool is pressed against the transform target portion to transform the plate. According to this configuration, a heat capacity of the peripheral portion of the plate can be increased. With this, when heating the vicinity of the peripheral portion of the plate, the peripheral portion can be prevented from becoming high in temperature. As a result, deformation of the peripheral portion of the plate can be suppressed.Type: GrantFiled: March 27, 2015Date of Patent: January 5, 2021Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Yoshiro Kabe, Yoshihide Imamura, Yuto Sakane, Kohei Mikami, Hayato Iwasaki, Hiroshi Kitano
