抄録

Tubes that have the rib internally are used as car parts, for example, structural component, radiator, shock absorbers, and so on. The existence of some holes at the rib enhances the function and value of the tubes. But, the tube with holed rib can not be formed by conventional extrusion. Then, we propose a method that extrudes with a ready made rib. The rib is a machined sheet metal with holes. While the tube is extruded, the rib is fed through a slit of mandrel. Tube and sheet are joined at the same time during extrusion. The mandrel has slit and guide. A guide position <i>h</i> that is a distance from die surface to front edge of the guide is a dominant parameter in this research. When guide position <i>h</i> is controlled, metal flow can be adjusted. We carried out an experiment to clarify the effect of guide position on joining by using A1050. Then, a tensile test clarified that joining strength between tube and rib is 40% of base material. Moreover, flatness was observed in measuring the outside diameter and the inside diameter of the tube.
