抄録
Barreling of the hollow cylinder was investigated in cold upsetting with ram pulsation. In the experiment of upsetting 18Cr-12Ni-2.5Mo austenitic stainless steel (JIS: SUS316), barreling was reduced by complete unload ram pulsation, especially by multiple pulsations with short forming strokes. On the other hand, barreling was not reduced by ram pulsation with partial unloading. In the case of hollow cylinder with pure aluminum (JIS: A1070), barreling was not reduced by both complete and partial unload ram pulsations. The mechanism of reduction in barreling was discussed from the viewpoints of friction at the die–workpiece contact interface, plastic heat generation, and elastic and plastic deformations. In the elastic–plastic finite element analysis, the stress state in the workpiece at reloading after complete unloading was considerably changed from that of the state before unloading. Therefore, the reduction in barreling in upsetting with complete unload ram pulsation was concluded to be mainly due to the elastic and plastic characteristics of the workpiece.
