The portable CNC plasma cutting machine technology was introduced into the domestic market in the 1990s. It has been favored by the market and users because of its rapid, high-efficiency and economical universalization. From the perspective of technology research and development, the development of portable plasma cutting technology was originally aimed at solving the problems of non-carbon steel materials such as stainless steel and aluminum cut by flame cutting. However, the development of portable plasma cutting technology has not only involved in a wide range of cutting, but also involved cutting and cutting of carbon sheet and carbon sheet for flame cutting. The main reason is that the plasma cutting speed is high and it is easy to set the cutting conditions. Automated, unattended operation. The gas cutting process requires frequent adjustment of the flame, the cutting speed is slow, and the preheating time limits the cutting productivity. In contrast, it is not suitable for automation and unmanned operation.
The key technology for air or oxygen plasma cutting is the life of consumables in the cutting torch. Due to the oxidizing properties of air or oxygen, the electrodes and nozzles in the plasma torch must be resistant to the high temperatures of the arc in the oxidizing atmosphere. Therefore, current electrodes use high-melting germanium materials and are embedded in copper with special processing methods. The nozzle adopts a double-layer air flow structure, which has the advantages of improving the air flow directionality, speed, ion gas purity, cooling, etc., protecting the nozzle and further compressing the arc. In addition, in order to reduce the electrode consumption, the cutting gas does not use pure oxygen but uses a mixed gas of nitrogen and oxygen at the time of arc starting, and adopts a relatively small gas flow rate, which is switched to oxygen after arcing. In addition, the contact of the nozzle with the cutting material during the cutting process will also damage the nozzle, which requires efforts on the height control of the cutting torch. In short, the life of the electrode and nozzle is greatly improved than in the past, and the corresponding oxygen plasma cutting current has reached a maximum of 500A. According to actual operation verification, taking the company JS series CNC cutting machine as an example, 400A oxygen plasma cutting, each electrode can work In 3.5 hours, each nozzle can work for 4.8 hours, which is greatly improved from the data presented in the related materials.
