Abstract

PURPOSE: To easily perform the controlling of hydraulic press, by controlling the motion of slide with the stroke length and oil pressure value.
CONSTITUTION: Stroke length analogue signal A is output to comparator 5 after it is converted into a digital value by A/D convertor 4 and, at the same time, the digital value is displayed on indicator 6. The output of digital switch 7 for setting stroke is also supplied to comparator 5, and, when both outputs coincide with each other, the comparator outputs the signal to selecting switch 8. Oil pressure value analogue signal B is also output to selecting switch 8 through A/D convertor 10 and comparator 11. When switch 8 is set to the contact point of stroke, output signal relay 9 is turned on, and, when is set to the contact point of oil pressure, output signal relay 14 is turned on. Moreover, when switch 8 is set to both, both relays 9 and 14 are turned on. In this way, the motion of slide can control the stroke and oil pressure.
