The invention discloses the plasma flame cutting machine digital electrical control system, and the control method thereof; and the plasma flame cutting machine digital electrical control system has high antijamming capability, can realize digital control and is high in control accuracy.

Description

technical field [0001] The invention relates to a plasma flame cutting machine, in particular to a digital electric control system of a plasma flame cutting machine and a control method thereof. Background technique [0002] Plasma flame cutting machine is a cutting machine that integrates plasma and flame cutting. At present, the plasma flame cutting machine is equipped with a separate electronic control system. The main problems of the electronic control system are: first, the control system has a complex structure, and it is an analog quantity to control the anti-interference ability or has high requirements for the plasma power supply; second, the control accuracy Low, especially in the process of controlling the plasma on the follow-up mechanism, the distance accuracy between the flame torch and the workpiece is very low. Due to the above reasons, when the distance between the plasma and flame torches and the workpiece changes, the machine needs to be stopped for adjus...

Problems solved by technology

At present, the plasma flame cutting machine is equipped with a separate electronic control system. The main problems of the electronic control system are: first, the control system has a complex structure, and it is an analog quantity to control the anti-interference ability or has high requirements for the plasma power supply; second, the control accuracy Low, especially in the process of controlling the plasma on the follower mechanism, the distance between the flame torch and the workpiece is very low accuracy

Due to the above reasons, when the distance between the plasma and flame torches and the workpiece changes, it needs to be stopped for adjustment, so the quality of the cutting parts is seriously affected, and steel plates will be wasted
