| Abstract: | A kind of D shape tube, with extending wings and interior convex ribs, hasbeen designed and produced by Continuous Extrusion forming machine. As a resultof it, the technology research of the die for this kind of tube has been introducedand the rectification of the strength of extrusion die has been carriedtheoretically.By analyzing the distortion regularity of metal which exists in theExtrusion of Conform and the geometry trait of this new type of tube, the rationalconstruction of mould has been selected. At the same time, the factors such as therate of mould flow, the depth of the drainage slot which plays an important roleon the forming height of interior convex ribs have been analyzed in this paper. |
