【発明の名称】プレスのブレークスルー緩衝装置およびその制御方法
Document Type and Number:
Japanese Patent JP3319786
Kind Code:
B2
Abstract:
A breakthrough buffer for presses, for reducing noise or vibration occuring during blanking using a mechanical press, and a control method therefor. The apparatus is provided with a buffer body (20) disposed below the punch (3) of a press (1) and cushioning the punch during the breakthrough of the press, a timing regulator (40) connected to the buffer body and regulating the timing of the same during the breakthrough of the press, and a controller (60) adapted to send out a command for a regulating position to this regulator. The noise or vibration occuring during the breakthrough of the press is detected, and a command signal is sent out from the controller (60) to the timing regulator (40) to regulate the timing of the buffer body (20), whereby noise or vibration occuring during the breakthrough of the press is minimized.
