Cutting torch and automatic ignition cutting gun

Abstract

The invention discloses a cutting torch and an automatic ignition cutting gun. The cutting gun comprises a cutting gun body, the cutting torch and a discharging device, the discharging device is arranged on the cutting gun body, and the cutting gun body is connected to a cutting torch main body of the cutting torch; a first electrode of the discharging device is electrically connected to a torch core, a second electrode is electrically connected to a torch cap and comprises the cutting torch main body, the torch core and the metal torch cap, and the torch core is connected to the cutting torchmain body; the torch cap sleeves the torch core and is connected to the cutting torch main body, the torch cap is in insulation connection to the cutting torch main body, and the distance between thefront end face of the torch cap and the front end face of the torch core is smaller than the shortest distance between the rear end of the torch cap and the cutting torch main body. Therefore, the cutting torch main body and the torch core can be respectively used as two electrodes of the discharging device, the electric sparks can be generated by discharging, the ignition can be carried out, thedesign and the process of the connection between the original cutting torch main body and the torch core can be reserved, the cutting torch structure is simplified, the production and processing areconvenient, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of torches, in particular to a cutting nozzle and a torch capable of automatic ignition. Background technique [0002] The traditional torch is usually ignited by an external fire source, such as a lighter or a match, which may cause burns to the igniter when it is ignited, and when it is operated outdoors, due to the strong wind, Difficult to light a fire. When working at high altitudes, holding a torch in one hand and igniting the fire in the other will also cause the danger of people or objects falling, or when working in special places, it is impossible to bring fire sources such as lighters into it, resulting in problems such as inability to work. [0003] And the cutting nozzle that the existing cutting torch that can automatically internally ignite is used, is that the oxygen outlet nozzle is insulated from the torch body, such as the electronic automatic internal ignition device of a kind of torch with public...

Problems solved by technology

[0002] The traditional torch is usually ignited by an external fire source, such as a lighter or a match, which may cause burns to the igniter when it is ignited, and when it is operated outdoors, due to the strong wind, difficult to light a fire

When working at heights, holding a torch in one hand and igniting the fire in the other will also cause the danger of people or objects falling, or when working in special places, it is impossible to bring a fire source such as a lighter into it, resulting in problems such as inability to work

[0003] And the cutting nozzle that the existing cutting torch that can automatically internally ignite is used, is that the oxygen outlet nozzle is insulated from the torch body, such as the electronic automatic internal ignition device of a kind of torch with publication number CN206608982U, that is, in the oxygen outlet An insulator is set between the nozzle and the nozzle cap connection thread, and the connection between the insulator and the nozzle cap connection thread and the oxygen outlet nozzle is poorly sealed, which is likely to cause problems such as air leakage, and the main body of the cutting nozzle is divided into an insulating part and an oxygen outlet. Mouth, making the production and processing complicated and the cost increased
