Abstract
PURPOSE: To improve the safety of machining operation when pressing a plate material by a press device equipped with top and bottom dies by controlling the operation of a hydraulic device for the dies by a solenoid valve having two solenoids.
CONSTITUTION: Movable die apron 7 is elevated and lowered by hydraulic device 9 toward and from fixed die apron 5 to bend a platelike material with both dies. Through the operation of the 1st solenoid SOL1 and 2nd solenoid SOL2 of solenoid valve 11, hydraulic device 9 leads pressure oil into upper and lower rooms to move up and down movable die apron 7. In this case, after the operation of movable die apron 7 is stopped temprarily at a proper position through a safety device, stop device and operation device, apron 7 is moved closely to fixed die apron 5 to fit the top movable die to the bottom die, so that the platelike material will be pressed on safety with both the dies.
