Automatic Ignition Of Cnc Plasma Tube Cutter - China

CNC plasma tube cutter are expensive and only suitable for thin plate cutting (usually thick plates take a long time to punch holes).

The precision of a fine plasma cutting machine can reach the lower limit of laser cutting.

The cutting surface quality is not much different, but the cutting cost is much lower than laser cutting.

In developed countries, there has been a trend of replacing flame cutting machines and laser cutting machines with cnc plasma rotary tube cutters.

plasma cutting machine continues to provide wide and flexible solutions with its low investment and operation cost advantages, being appropriate to production lines and automation, improved accurate cutting quality.

cnc plasma tube cutter The so-called automatic ignition is that the system controls the ignition solenoid valve to turn on the gas, and at the same time, controls the power supply to the ignition system.

The spark plug is ignited through the high-voltage circuit to ignite the gas to achieve ignition.

The entire ignition process only appears within 1-2 seconds after the "fire test" or "cutting" operation.

The fault check must also be carried out at this time.

1 - No gas is emitted during ignition.

While operating the "fire test" button, open flames can be used to ignite the ignition point of the igniter to confirm whether there is gas injection during ignition.

If there is no gas injection, you can check the main control board and the solenoid valve indicator according to the gas path fault check and troubleshooting methods.

If the indicator lights of the main control board and the solenoid valve are normal, and there is no valve clogging, the small hole of the gas nozzle on the igniter may be clogged.

The way to confirm the diagnosis is to loosen the nut under the adjusting knob on the igniter and place the knob in the water to see if there is gas ejection during ignition.

If there is gas and there is no gas in the igniter's fire, it must be the gas nozzle is blocked.

The gas nozzle hole is very small, Ф0.4mm.

The treatment method uses a waste hand to use a steel saw blade to grind a small, slender tip, and then use it to clear the small hole.

2 - The spark plug does not ignite during ignition.

When igniting, there should be a clear discharge spark between the spark plug and the igniter body, which can be clearly seen, and the sound of a clear spark discharge can also be heard.

If the spark plug does not ignite, check whether the main control board's ignition indicator is lit for 1-2 seconds when the "fire test" key is operated to confirm whether the main control board's ignition control is correct.

Whether there is carbon collection on the spark plug will also cause the spark plug not to ignite, which needs to be removed.

Secondly, check the high voltage package connected with the spark plug, and their interconnection and connection plug.

DC3V (two ordinary batteries) voltage is applied to the input terminal of the high-voltage package.

Spark discharge should be generated between the two output lines of the high-voltage package (the distance between the two lines is 2-10mm); otherwise, the high-voltage package will be damaged.

3 - There is gas during ignition, and the spark plug also ignites, but it still cannot ignite.

The main reason for this phenomenon is that the gas concentration is too high.

Gas concentration is not suitable.

It often fails to ignite normally, especially when using a gas such as coal gas and propane.

It needs to be solved by adjusting the "adjustment knob" and changing the gas concentration.

cnc plasma tube cutter The working principle of the control system of the cnc plasma rotary tube cutters The main beam longitudinal motion control of NC system for cnc plasma tube cutter, control the car with lateral movement of cutting torch, combination of horizontal and vertical motion trajectories become torch and workpiece is cut to shape.

At the same time, the PLC in the control system realizes the action and timing control of the gas regulating valve of the cutting gas path.

In the actual use of numerical control flame cutting machine, in order to keep the height of the cutting head and the steel plate constant, it also needs to be equipped with automatic capacitor height adjusting device.
