1. After the cutting die setting work is completed, place the cut material on the rubber plate, then place the die on the material, and then push the feeding plate into the cutting area.
2. Press the cutting switch of the cutting machine with both hands. At this time, the cutting plate is lowered and pressurized to the die. After the cutting die cuts the material, it automatically rises to the position before starting to stop.
3. When punching the material with the cutting machine, if it is found that the material is not completely cut, adjust the 03 cutting depth controller to rotate the "pressure system" clockwise in the opposite direction; if the knife mold is pressed into the rubber sheet too deep, it will be " The pressure system "rotates counterclockwise. The longer the adjustment time, the deeper the cutting depth. Try to adjust until the die is slightly pressed into the rubber plate.
4. Pull the feeding plate out of the cutting area, take out the cut material, and complete a blanking process.
The failure of the reversing valve of the cutting machine includes: the valve cannot be reversed or the reversing action is slow, the gas leaks, and the electromagnetic pilot valve is faulty.
(1) The reversing valve cannot be reversed or the reversing action is slow, generally caused by poor lubrication, spring jamming or damage, oil stains or impurities jamming the sliding part. In this regard, first check whether the oil mister is working properly; whether the viscosity of the lubricating oil is appropriate. If necessary, replace the oil, clean the sliding part of the reversing valve, or replace the spring and the reversing valve.
(2) After the valve is used for a long time, the valve reversing valve is prone to wear of the valve core seal, damage to the valve stem and the valve seat, resulting in gas leakage in the valve, slow valve operation or failure to normal commutation. In this case, replace the seal, stem and seat, or replace the reversing valve.
(3) If the inlet and exhaust holes of the electromagnetic pilot valve are blocked by oil and other debris, the sealing is not strict, the movable iron core is stuck, the circuit is faulty, etc., and the reversing valve can not be normally reversed. For the first three cases, the sludge and impurities on the pilot valve and the moving iron core should be cleaned. Circuit faults are generally divided into two types: control circuit faults and electromagnetic coil faults. Before checking the circuit fault, first turn the manual knob of the reversing valve a few times to see if the reversing valve can be normally reversed under the rated air pressure. If the commutation is normal, the circuit is faulty. During the inspection, the voltage of the electromagnetic coil can be measured by the meter to see if the rated voltage is reached. If the voltage is too low, the power supply in the control circuit and the associated stroke switch circuit should be further checked. If the reversing valve cannot be reversed normally at the rated voltage, check the connector (plug) of the solenoid for looseness or contact. The method is to unplug the plug and measure the resistance of the coil. If the resistance is too large or too small, the solenoid is damaged and should be replaced.
