| description | The invention belongs to the technical field of aviation aircraft sheet metal part machining, and discloses a forming device and a manufacturing method of a thin-wall annular part with a U-shaped reinforcing edge. A set of spinning die is newly designed to be used for spinning forming, the technological process is optimized to be spinning forming-welding, and therefore accurate manufacturing of the thin-wall annular part with the U-shaped reinforcing edge is achieved. A spinning die used for spinning forming is low in manufacturing cost, the requirement for the skill level of an operator in the production process is low, machining is mainly adopted in the forming process, parts are uniform in size and good in surface quality, and bad faults such as product scrapping do not occur. After forming, the two free ends of the part are combined in a welding mode, and therefore the thin-wall annular part with the U-shaped reinforcing edge is accurately manufactured. According to the spinning die used by the invention, |
