Description

Dust extinguishing flame-retardant device for laser cutting machine

Technical Field

The utility model relates to a dust extinguishing flame retardant device for laser cutting machine. Belongs to the technical field of machinery.

Background

The laser cutting machine focuses laser emitted from a laser into a laser beam with high power density through an optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach a melting point or a boiling point, and simultaneously, the high-pressure gas coaxial with the laser beam blows away the molten or gasified metal. And finally, the material is cut along with the movement of the relative position of the light beam and the workpiece, so that the cutting purpose is achieved.

The laser cutting processing is to replace the traditional mechanical knife by invisible light beams, has the characteristics of high precision, quick cutting, no limitation on cutting patterns, automatic typesetting, material saving, smooth cut, low processing cost and the like, and can gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser tool bit is not in contact with the workpiece, so that the surface of the workpiece cannot be scratched in the working process; the laser cutting speed is high, the cut is smooth and flat, and subsequent processing is generally not needed; the cutting heat affected zone is small, the deformation of the plate is small, and the cutting seam is narrow; the notch has no mechanical stress and no shearing burr; the processing precision is high, the repeatability is good, and the surface of the material is not damaged; the numerical control programming can be used for processing any plan, the whole board with large breadth can be cut, a die does not need to be opened, and the method is economical and time-saving.

The laser cutting machine has the disadvantages that a large amount of dust is generated in the process that the heat-dissolving metal plate is blown away by high-pressure air in the laser cutting, the pollution particles with the diameter within the range of 2-10um can easily reach the throat part of a human body through breathing, the dust with smaller diameter can even directly enter the lung of the human body, and the dust is easily inhaled for a long time in production and labor to cause an occupational disease of pneumoconiosis, so the dust control in the laser cutting is very important.

The chinese utility model patent (application No. 201520628733.X) discloses a laser cutting machine with a dust absorption box, wherein dust generated in the cutting process is blown to one side of the protection cover through a blower on the protection cover, and is blown into the dust collection box through a guide pipe through the dust absorption opening. The above patent has the following problems: the dust generated in the laser cutting process has extremely small particle size and may contain oil and sparks, and the dust may enter the dust collection box through the flame-retardant pipe, so that the dust accumulated in the dust collection box catches fire, and accidents are caused.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned not enough, provide a dust extinguishing flame retardant device for laser cutting machine.

The purpose of the utility model is realized like this:

Furthermore, a partition plate is arranged at the top in the water tank, the partition plate divides the upper part of the water tank into an inlet area and an outlet area, the inlet area is communicated with the air inlet flame-retardant air pipe, and the outlet area is communicated with the air exhaust flame-retardant air pipe.

Furthermore, the liquid level of the water in the water tank is lower than the height of the fire-retardant net.

Furthermore, the fire-retardant net is a stainless steel plate which is uniformly provided with small holes.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model relates to a dust extinguishing flame retardant device for laser cutting machine sets up between laser cutting machine and dust shaker, has prolonged the stroke of the dust that has the mars for the mars go out easily.

2. The utility model relates to a dust extinguishing flame retardant device for laser cutting machine goes out through the twice of water and fire blocking net and puts out, and the mars in the dust must put out the processing, and remaining dust gets into the fire-retardant tuber pipe of exhaust along with the air current through the aperture of fire blocking net and discharges, is collected the processing by the dust shaker at last, has stopped the dust shaker hidden danger of catching fire.
