Embodiment Construction
[0032] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0033] like Figure 1-Figure 7 As shown, the precision roll-forming method of the large horizontal high rib thin-walled ring of the present invention comprises the following steps:
[0034] S1, obtain the ring blank 2, the blank 2 is a ring with a rectangular cross-section, which can be produced by upsetting, casting, punching, punching, extrusion, flat end face and turning. The parts made by the method of the present invention are large thin-walled rings 8 with horizontal and high ribs. like figure 1 , 2 As shown, the height of blank 2 is h, and the inner diameter of blank 2 is D 1 , the outer diameter of blank 2 Among them, the inner diameter of the large horizontal high rib thin-walled ring is D 1 , the skin t...
