Abstract: A
method of setting up a pressure-stroke characteristic of the
working liquid in hydraulic drawing is studied. A
pressure-stroke characteristic and software for controlling its
forming process are also developed. And a set of pressure
controlling devices with PLC as a central processor are
designed. It can be got from the relevant experiments that the
pressure-stroke characteristic is correct and its control for
forming process is available.
Key words: Hydraulic drawing Working liquid
