A kind of plasma arc cutting torch and its electrode

Abstract

The application discloses an electrode for a plasma arc cutting torch. The electrode comprises an electrode body and a consumable accessory fixing part, wherein a first fixed cavity is formed in the electrode body, one end of the consumable accessory fixing part is placed in the first fixed cavity and is detachably connected to the electrode body, a second fixed cavity is formed in the consumable accessory fixing part, two ends of the second fixed cavity communicate with the outside, a limiting part is arranged in the second fixed cavity, a propelling mechanism is arranged in the first fixed cavity, and the propelling mechanism is in contact with a consumable accessory located in the second fixed cavity, so that the consumable accessory is in contact with the limiting part all the way. The application further provides the plasma arc cutting torch. The electrode for the plasma arc cutting torch disclosed by the invention is long in service life and low in using cost.

Description

technical field [0001] The present application relates to the technical field of cutting equipment, in particular to an electrode for a plasma arc cutting torch; the present application also relates to a plasma arc cutting torch. Background technique [0002] Plasma arc cutting is a process in which a high-temperature, high-speed plasma arc is used as a heat source to partially melt the workpiece to be cut and use the mechanical scour force of compressed high-speed airflow to blow away the melted metal or non-metal to form a narrow incision. It is mainly composed of welding power supply, cutting torch, control system, gas circuit and water circuit. The cutting torch is a device for generating plasma arc, and the electrode is an important part of it. [0003] The electrode is an extremely important consumable item in the accessories of the plasma arc cutting system. As the wearing part of the cutting system, the electrode is worn out and replaced during use. The phenomenon. ...

Problems solved by technology

[0003] The electrode is an extremely important consumable item in the accessories of the plasma arc cutting system. As the wearing part of the cutting system, the electrode is worn out and replaced during use. The phenomenon

At present, the electrode on the market is a whole non-detachable structure. After the hafnium wire is consumed, the entire electrode needs to be replaced, and the service life is low, which greatly increases the cost of the user.
