Abstract

The invention belongs to the technical field related to processing of axial inner rib cylindrical parts, and discloses a sizing rolling forming method of an axial inner rib cylindrical part. The method comprises the following steps of (1) firstly, providing N driving rollers, wherein an annular limiting groove is formed in the middle of each driving roller, then, placing an annular blank to be formed in the limiting grooves of N-1 corresponding driving rollers, and then separately accommodating the blank in the limiting grooves of the N driving rollers; (2) placing an axial groove core rollerin a through hole formed by the blank, and forming a profiled groove in the axial groove core roller; and (3) performing active rotation by the N driving rollers at the same rotating speed and in thesame direction so as to drive the blank to rotate, wherein the axial groove core roller rotates under the driving by the blank till forming of the axial inner rib cylindrical part is finished. The method improves the quality and reduces the cost.
