Operating Procedures

1. Before starting the machine, find out the name and role of each part of the machine, see the previous article in the public number for details.

2. When you turn on the machine, open the air valve at the back of the machine first, then check whether the three air pressure gauges are in place (the three pressure gauges are A balance pressure gauge is generally adjusted to 0.4mpa-0.5mpa, B clutch pressure gauge is generally adjusted to 0.4mpa-0.6mpa, C non-adjustable pressure gauge is generally specified at 0.4mpa) non-professionals cannot move the pressure gauge.

3. Turn on the main power switch, then turn on the motor start switch while the indicator HL2 is on. When the main motor stops rotating, the indicator light goes out. Before the machine action, make the air pressure reach specified value, start the motor will overload protection knob switch to the normal position.

4. How to choose inching, single, continuous, how to choose non-continuous, disconnected, continuous break.

● Inch move: the continuous knob switch is placed in a non-continuous position, and the selector switch is placed in the inch move position. The console quick changeover switch is set to inching, then both hands press and close the two-hand button, the slider action two-hand button releases, and the slider action is stopped.

● Single: The continuous knob switch is placed in the non-continuous position, the selector switch is placed in the single position, the console quick changeover switch is set to the disconnected position, while pressing the two-hand switch button, the slider moves, the slider stroke exceeds 135 degrees release the two-hand button the slider continues to move to the upper dead center. If within 135 degrees let go of the two-hand button slider immediately stop. Place the two-hand/foot knob in the foot position for a single foot operation, but attention must be paid to operational safety.

● Continuous: is the continuous knob switch placed in the continuous position, selector switch is also placed in the continuous position, press the two-hand button, the slider action for 5 seconds release the two-hand switch button, the slider continues to run this time the machine in a continuous state, press the continuous stop button slider back to the upper dead center after stopping or the two-hand, foot knob placed in the foot position can not be continuous operation.

● Slider adjustment: usually put the slider adjustment knob in the cut-off position, and then tap the up button or down button by hand.

● Overload protection: Usually set the overload protection knob to the normal position, when the red indicator lights up when overloaded, immediately set this knob to the reset position.

● Slider travel is set too low to play "dead": immediately turn off the motor start switch, and so the machine tool iron disk flywheel completely stop, the machine tool rotation switch. Play to the reverse position and then hands to play the inching will slowly return the slide guide to the upper "dead" point position 0 degrees.

● How to use the counter: When this knob is released in the "on" position, the counter will start counting the number of slider trips.

● How to use the "Ejector": Generally put the knob in the "Auto" position, the airflow will be blown out with the press stroke at the same time, when the machine is not in the press operation, if you need to use the ejector, put the knob in the "Manual" position, and tap the knob. When the machine is not in stamping operation, if you want to use the ejector, put the knob in the "manual" position, tap the knob once, and the ejector will blow once.

● Emergency stop button: In any case of operation, press this button by hand downward, the machine will immediately stop operation, downward when the button is self-locking, when you start the operation again before you must reset this button, (turn the button in the direction of the arrow).

● Photoelectric protection device: If the machine tool is equipped with photoelectric protection device, so that the following functions, that is, when the photoelectric protector power on, the slider travel in the range of 0 degrees to 135 degrees, when blocking the light beam of the protection device, the slider immediately stop in any position, the machine tool for inching operation, no photoelectric protection.

5. Recognize the mastery of all the above, then start the machine tool motor first observe a minute to listen to the machine tool running sound is normal, the machine tool running direction, and the machine tool lubrication parts are good.
