Embodiment 1
[0036]This embodiment is a forming process of a thin-walled part of a rotating body with an annular inner reinforcing rib, and mainly designs a core mold for forming a thin-walled part of a rotating body with an annular inner reinforcing rib.
[0037] The geometric shape of the thin-walled part of the rotary body with the annular internal reinforcement described in this embodiment is as follows: figure 1 As shown, the inner diameter is 300mm, the axial length is 500mm, and the wall thickness is 10mm. The inner wall has three annular inner ribs 1 with a width of 50mm and a height of 5mm along the axial direction, and the distance between them is 100mm. The distance between the end faces is 75mm.
[0038] The core mold for forming the above-mentioned rotating thin-walled part proposed in this embodiment includes a base mold 9 , a shape mold 10 and a fixing pin 11 .
[0039] Base mold 9 is made of die steel 4CrMnSiMoV, which consists of base mold main body 2 and draft end 3. Th...
