Research of the Buffer Device for Fine Blanking Hydraulic Press

By analyzing sheet metal blanking process and buffer technology of hydraulic press, several kinds of blanking buffering device were designed based on adaptive working conditions. At the same time, a buffer device with accurately adjusted buffer point position and automatically tracking blanking force was developed, so vibration and noise could be reduced, and it was successfully used in the blanking hydraulic press. Meantime, the structure of different devices and application status were analyzed, which had directive significance for practical production.
