PRESSURE JUDGEMENT METHOD OF TRACK LINK IN TRACK PRESS

摘要

The method comprises detecting the ram load pressure when fitting the link, comparing the detected output with both lower limited pressure value (PL) and upper limited pressure value (PH), both values being predetermined on the basis of the fitting pressure range defined to the concerned link (6), interrupting the pressing operation of the ram within the predetermined pressing time interval (T) when the compared value is over the PH, while descriminating whether the total sum of the presing time interval above the PL is greater than the predetermined time period or not.
