Injection type metal burning torch

Abstract

The invention discloses an injection type metal burning torch. The injection type metal burning torch comprises a burning torch head and a burning torch handle. The burning torch head is rectangular and is connected with the burning torch handle. A nozzle is arranged under the burning torch head and is a cylindrical nozzle. The nozzle is connected with an air mixing component. The air mixing component is a mixing cavity which is connected with gas conveying channels. An adjusting rotary knob is arranged on the burning torch handle and provided with a scale adjusting gear. A shielding component is arranged around the nozzle, eyes of an operator can be further prevented from being burnt by hard light, and the personal safety of the operator is ensured. The nozzle is provided with a high-temperature-resistant coating so that the high-temperature resistance of the nozzle can be improved, the nozzle is prevented from cracking caused by the influence of high temperatures, and the replacement frequency of the nozzle is lowered.

Description

technical field [0001] The invention relates to a cutting torch, in particular to an ejector-suction metal cutting torch. Background technique [0002] In the field of welding, it needs to be widely applied to the cutting torch. The cutting torch can easily cut off the parts. At the same time, the torch can also perform welding operations. When many cutting torches are used at present, there will be a lot of strong light during welding. , the operator needs to wear an eye protection device to protect the eyes, but sometimes such a protection device cannot protect the eyes well, and it still causes the risk of burning the eyes, which brings personal injury to the operator, and some parts are broken When the gun is in use, the nozzle often cracks at high temperature, and the cracked nozzle needs to be replaced. The high-frequency replacement of the nozzle will increase the use cost of the cutting torch and affect the use effect of the cutting torch. Contents of the invention...
