EXPERIMENTAL INVESTIGATION ON THE TUBE FORMING PROCESS

초록

In this paper, the tube forming by radial-forward extrusion is analyzed by experiments. The paper discusses the effect of process variables such as gap height, relative gap width and the die corner radius on tube forming. The influence of deformation patterns of flange in radial extrusion on forward extrusion for tube forming is investigated and summarized in terms of the forming defects. Furthermore the external defects are shown experimentally during the operation.
