抄録

Tubes with an internal rib have a high strength in comparison with those without a rib. These tubes can be used, for example, as structural parts, heat sinks, and impact absorbers. The existence of some holes at the rib enhances the function and value of the tubes. The appropriate positioning of holes at the rib reduces the weight of structural parts while preserving strength. In the case of heat sinks, holes change the fluid flow and realize effective heat transfer. In this research, a new extrusion method is proposed for manufacturing tubes with a holed rib. The method involves the use of a unique mandrel that has a slit along its axis and two guides at the slit exit. A holed plate is fed through the slit and made into a holed rib of the tube. The flow of the billet is investigated. In particular, the effect of the guide height is clarified in this study.
