Abstract

The invention relates to the technical field of manufacturing and forming, and provides a forming device and a forming method for a thin-walled annular part. The forming device structurally comprisesa fixed seat, a driving roller, a forming roller and a driving part, wherein the the driving roller and the forming roller are movably connected with the fixed seat, the forming roller is nested in aninner cavity of the driving roller, and the driving part is in driving connection with the forming roller through the driving roller; and the forming device further comprises a core roller which performs feeding motion in the radial direction of the forming roller. According to the forming device of a revolving body, the problem that a thin-walled revolving body is difficult to form is solved, the production of the thin-walled revolving body is realized, the problem of plastic instability is solved, and the limitation on the wall thickness of a thin-walled part is broken through.

Description

technical field [0001] The invention relates to the field of manufacture of revolving bodies, more specifically, to a forming device and method for forming a revolving body of a thin-walled ring. Background technique [0002] The rotary body in the ring is widely used in many industrial fields such as aerospace, petrochemical, energy transportation, shipbuilding, weapons, and metallurgy. At present, the production process of the rotary body mainly adopts rolling. Rotary body rolling is mainly carried out on vertical ring rolling machine or horizontal ring rolling machine. main manufacturing technology. [0003] At present, there are four forming methods for the rotary body: horse frame reaming, rolling forming by rolling mill, shape correction after rolling, and flash welding forming, among which: [0004] Free forging ring forging production process that uses simple tooling such as horse frames and horse rods to locally deform the produced ring blank, so that the outer d...
