Description

Technical Field

[0001] The utility model belongs to the technical field of steel plate processing, in particular to a steel plate laser cutting smoke emission pipeline. Background Art

[0002] The working principle of the laser cutting machine is to use a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the light beam moves on the material, the holes continuously form a very narrow (such as about 0.1mm) slit to complete the cutting of the material. In the process of steel plate processing, the steel plate needs to be cut. The smoke hazards generated by the laser cutting machine are easily ignored by the operator. The high temperature generated by the laser acts on the processed material and will produce a large amount of smoke and dust particles. The smoke generated has a strong irritating smell and contains a small amount of toxic gases. After being absorbed by the human body, it will seriously endanger the health of the operator. At the same time, if the smoke is not dealt with immediately, it will also cause corrosion hazards to the parts of the cutting equipment. Therefore, the smoke generated needs to be dealt with in time while the laser cutting machine is working.

[0003] The prior art still has the following deficiencies:

[0004] The working parts of the prior art laser cutting machine and the cutting points on the cutting material are all in an exposed state.
