Ring rolling, also known as ring rolling or hole reaming, mainly uses the ring rolling mill and rolling pass to make the ring produce continuous local plastic deformation, and then
Pipe molds are large-scale precision molds used for the production of centrifugal ductile iron piping devices. They are the main consumable spare parts in the cast pipe industry, a
Folding defects of bending forgings Bending forgings are commonly used structural forgings, mainly including connecting rods, crankshafts and pipe joints. Most of the defects of th
Among the forgings, most of them are shaft forgings, and their forming dies are falling dies, which are composed of upper and lower parts. During forging, the forgings rotate aroun
Die forgings have many closed sections, the distance between the two ribs is short, the ribs are thin, the distance between the two ribs and the thickness of the web are large, and
Difficulty in forging 1.1 The difference between the flange diameter of the eccentric shaft and the rod is 540mm. When the shank is formed, the flange is subjected to enormous tens
