Abstract
The present invention belongs to the technical field of metal forming manufacturing and discloses an integral forming method for a large-size thin-walled ring shell. The integral ring shell obtained by the forming method of the present invention has only one circumferential weld seam and one radial weld seam. If the two weld seams are located in an excisable process segment region, the target part without weld seams can be obtained after the process segment is cut off. The forming method of the present invention adopts a local thermal expansion forming method, plastic deformation occurs only in mold-constrained high temperature regions in a single local forming process, and a part with each region meeting the requirements can be obtained after several local thermal expansion forming processes. The forming method of the present invention can obtain two open cross-sectional ring shell components or multiple segmented ring shell components at one time.
