Die Motions of New Forging Process Using Intermediate Die Assembly

摘要

The die motions of a new forging process for automation with an intermediate die assembly called hamburger were analyzed through high-speed video pictures. The results showed that the upper die that is assembled in the hamburger and retained over the lower die collides few times . with the ram and workpiece, but sound products can be obtained with less sticking in spite of the lowered impacts of hit.
