Laser technology has been widely used in the field of sheet metal cutting, the domestic CNC laser cutting machine industry is developing rapidly. Laser cutting is a method of cutting materials by heating and melting (evaporating) by laser irradiation with high density energy. Laser cutting machine in cutting workpiece, auxiliary gas and laser beam coaxial jet, cutting process produces a lot of soot.
The harm of laser cutting dust
Laser cutting produces very fine particles of smoke or aerosol mixture, generally only a few microns high, will stimulate people's eyes and respiratory system, causing cough, eye irritation and other physiological irritation reaction. It is generally believed that particles with an aerodynamic particle size of less than 7 "m can enter the deep layer of the lungs and permanently reside in the lungs, which may cause layer lung diseases such as pneumoconiosis.
If there is no dust removal device or dust removal effect is not good, cutting smoke dust not only pollution precision parts cutting head, affect the real life and stability, but also serious pollution of the working environment, harm the health of the staff.
With the continuous increase of environmental protection by the state, as well as the continuous enhancement of environmental awareness of enterprises, the application of laser cutting equipment supporting dust removal system has been paid more and more attention by people. More and more laser equipment manufacturers will support dust removal equipment as a standard auxiliary laser cutting machine.
Laser cutting dust removal system consists of three parts: (1) bed smoke dust collection → (2) pipeline transportation → (3) dust collector; The three parts complement each other to complete the cleaning of laser cutting dust. The dust trapping design of the real bed plays a very important role in the dust removal effect.
1. Dust collection:
Machine dust collection system, including flow design, suction tuyere position, suction tuyere size, etc.
2. Pipeline transportation:
It is composed of dust conveying pipe of machine tool bed and connecting pipe from bed to dust collector.
3. Dust collector:
Provide the power source for vacuuming, and purify the cutting dust collected by the machine tool.
