Combined practice, the technology difficulties of sheet forgings with inner hole were introduced, for which the optimized design of dies for punching and cutting for top-plate forging was put forward.
In this paper, the authors put forward a set of formulae which can be used to compute accurately motion parameters of both plunger and outer slides of eight-connecting bar platepunching machine.
