Problems solved by technology

[0007] 3) Once the double arc phenomenon occurs, the nozzle becomes the electrode of the parallel arc and passes the parallel arc current, and the cold air film barrier between the main arc and the inner wall of the nozzle hole is destroyed, so that the nozzle is strongly heated, and the nozzle is easy to burn out

Embodiment Construction

[0037] The present invention will be described in detail in conjunction with accompanying drawing now. This figure is a simplified schematic diagram only illustrating the basic structure of the present invention in a schematic manner, so it only shows the components relevant to the present invention.

[0038] Such as Figure 2-5 As shown, a kind of plasma arc cutting torch of the present invention, comprises cutting torch body 13, and the rear portion in described cutting torch body 13 is provided with upper inner insulator 14, and described upper inner insulator 14 is provided with gas pipe 12 and pilot arc The line 11 and the upper inner insulator 14 are made of ceramic materials, which mainly isolate the high-frequency voltage of the spout base 10 and the electrode base 8 of the outer layer. The front portion of the torch body 13 is provided with a spout 2, and the spout 2 is connected to the outer edge of the upper inner insulator 14 through the spout base 10, and the rea...

Abstract

The invention provides a plasma arc cutting torch. The plasma arc cutting torch comprises cutting torch body, an electrode and a nozzle and is characterized in that the inner hole of the nozzle is of a sectional circular horn shape and provided with a central hole in the center, and the nozzle is main made of red copper. The electrode is arranged in the nozzle and mounted on an electrode base, the middle section of the electrode is concave inwardly to form a calabash shape, the space between the nozzle and the electrode is expanded, positive electric ions on the electrode can be prevented from being transmitted to the nozzle from a non-central-hole position, and a double-arc effect is avoided.

Description

technical field [0001] The invention relates to the technical field of arc cutting torches, in particular to a plasma arc cutting torch. Background technique [0002] The existing machine-used plasma arc cutting torches in the Chinese market are simple in design and structure, and the production process is poor. In addition, there are no technical colleges in this area in China, and there is a lack of technical knowledge education. Even if there are manufacturers, most of them are imitated foreign technologies. There is no ability to independently innovate and design cutting torches, so the technology has been lagging behind the times. The cutting torches produced have weak cutting ability, poor cutting quality, short service life of consumable parts, and high cost of use. In the domestic market, when the current reaches 120A and above, the inside of the cutting torch body must be cooled by water circulation, including the air-cooled cooling method inside the cutting torch i...
