Operating procedures

1. Before starting, make clear the name and role of each part of the machine tool. For details, please refer to an article in the public number.

2. When starting the machine, first open the gas valve behind the machine, and then check whether the three pressure gauges are in place (the three pressure gauges are A balance pressure gauge generally adjusted to 0.4Mpa-0.5mpa, B clutch pressure gauge generally adjusted to 0.4MPa-0.6mpa, and C unregulated pressure gauge is generally set at 0.4mpa). Non-professionals should not move the pressure gauge.

3. Turn on the main power switch, and then turn on the motor starting switch at the same time the indicator HL2 will be on. The indicator light goes out when the main motor stops turning. Before the machine tool is operated, the air pressure shall reach the specified value, and the starting motor shall hit the overload protection knob switch to the normal position.

4. How to choose inching, single, continuous, how to choose discontinuous, disconnect, disconnect.

Inching: the continuous knob switch is placed in a non-continuous position, the selection switch is placed in the inching position. Set the quick switch of the control console to inching, and then press the two-handed button with both hands. The two-handed button will release and the slider will stop.

Single: the continuous knob switch is placed in a non-continuous position, the selection switch is placed in a single position, the control console quick switch switch to the open position, and press the double hands switch button, the slider action, the slider stroke exceeds 135 degrees release the double hands button slider continue to move the top dead point. Stop the slider immediately if you release both hands within 135 degrees. Place both hands/foot knob in foot position, single foot operation can be carried out, but must pay attention to operation safety.

Continuous: is the continuous knob switch is placed in a straight position, switch is placed in a straight position, according to us both hands button, switch button, open the slider move 5 seconds hands sliding piece of work when the machine is in continuous state, according to us straight after the stop button the slider back to the top dead center stop or put hands and feet on knob at the pedal position can't continuous operation.

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

Overload protection: usually the overload protection knob to the normal position, when the overload red light on, immediately put the knob to reset position.

When the stroke of slider is too low to hit "dead" : immediately turn off the motor starting switch, and when the iron disc flywheel of machine tool stops completely, turn the switch of machine tool. Hit the reverse position and then inch with both hands to slowly return the slider to the upper "dead" position 0 degrees.

How to use the counter: when this knob is released in the "on" position, the counter begins to count the number of slides.

How to use "ejector" : the knob is generally placed in the "automatic" position, and the air flow is blown out with the stroke of the press at the same time. When the machine tool is not in the stamping operation, if the ejector needs to be used, the knob is in the "manual" position, and the knob is moved once, and the ejector blows once.

Emergency stop button: under any condition of operation, press this button down by hand, the machine will stop operation immediately, and the button down will self-lock. When you start operation again, you must reset this button (turn the button in the direction of the arrow).

Photoelectric protection device: if the machine is equipped with photoelectric protection device, it has the following functions, that is, when the power supply of the photoelectric protection device is turned on, the stroke of the slide block is in the range of 0 degrees to 135 degrees, when the beam of the protection device is cut off, the slide block immediately stops at any position, the machine tool for inching operation, no photoelectric protection.

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

7. Additional instructions

Production must first understand the drawings and the technical requirements on the drawings, especially the perspective of sheet metal drawings and drawing of the cutting algorithm, if there is any unclear place, immediately ask the shift leader or engineer, to do a good habit of self-checking quality in the operation.

The semi-finished products are placed in the product turnover area and pasted with a label card before being sent to the next process.

After the use of the mold, must check whether to repair or maintenance, and then can be put back to the mold, abnormal mold can not be put back to the mold, must write the mold maintenance list to the mold department. Make sure that the label is placed in the designated position when the mold is placed back.

It is necessary to make clear the lubrication part of the machine tool and the time of filling oil, as well as the name of the lubricating oil and how to fill oil.
