Description

Technical Field

[0001] The utility model relates to the technical field of cutting mechanisms, in particular to a cutting mechanism of a flame cutting machine. Background Art

[0002] Flame cutting machine is a kind of cutting equipment that uses gas and oxygen or gasoline and oxygen to cut metal materials. It is mainly used in heavy industry. From the process point of view, according to the metal material and the thickness of the metal to be cut, it is recommended to use flame cutting for carbon steel plates above mm, because the thermal deformation of such steel plates is very small. Stainless steel and non-ferrous metals cannot be cut with flame because stainless steel produces a high-density oxide layer on the surface after heating, which prevents heat from transferring downward, thus affecting the melting of the plate; non-ferrous metals such as copper and aluminum have strong heat dissipation capacity, which causes the heat on the cut surface to dissipate quickly, also affecting the melting of the plate.

[0003] However, the cutting mechanism of the existing flame cutting machine has a nozzle that is not easy to replace, which may limit the equipment's adaptability to different materials and cutting requirements. When the nozzle is worn or needs to be replaced, if the replacement process is complicated and time-consuming, it will directly lead to a decrease in production efficiency. In addition, the temperature of the plate after cutting is high, resulting in the problem of waiting for automatic heat dissipation affecting production efficiency.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a cutting mechanism of a flame cutting machine is proposed. Utility Model Content

Then the connecting pipe 107 is connected to the fuel and oxygen input pipes, and the mixed gas is ignited by the spark igniter.
