Abstract

The utility model discloses a people's air defense door laser cutting device, including the laser head that is used for laser cutting, still establish the ring type jet head in the laser head outside including the cover, a plurality of fumaroles of terminal surface distribution before the jet head, the fumarole extend to jet head rear end and with the annular air cabin intercommunication of jet head rear end, the external gas pipeline of carrying inert gas in air cabin, the jet head outside still overlaps and is equipped with annular brush, the brush hair front end of brush is suddenly in the setting of laser head terminal surface. This people's air defense door laser cutting device can avoid the splash adhesion after the cutting again on people's air defense door leaf surface when conveniently cutting.

Description

Laser cutting device for civil air defense door

The technical field is as follows:

the utility model relates to a people's air defense door processing equipment specifically says a people's air defense door laser cutting device.

Background art:

the non-metallic composite material is a mixture, plays a great role in many fields, is applied to the door leaf structure of the civil air defense door in recent years, replaces the original concrete and steel structure, the forming is generally finished by a method of layer-by-layer covering, because the forming precision of the die is not high and the edges of the formed product are not neat, the phenomenon of burrs at the edges when the civil air defense door leaf is formed requires to be cut at the later stage, the products are easy to be layered when the drill bit is used for punching and the cutter is used for cutting the edges, the laser cutting is used, because the laser cutting realizes cutting by utilizing high-energy instant burning, the energy impact force is very high, so that a plurality of splashes are simultaneously sprayed during burning through, and the splashes contain burning particles which fall onto the door leaf and are adhered to the surface of the door leaf to form particles, so that the appearance is influenced.

The utility model has the following contents:

the utility model aims to solve the technical problem that a can avoid the people's air defense door laser cutting device of splash adhesion on people's air defense door leaf surface after the cutting when providing one kind convenient cutting.

The technical solution of the utility model is, a people's air defense door laser cutting device is provided, including the laser head that is used for laser cutting, still establish the ring type jet head in the laser head outside including the cover, a plurality of fumaroles of terminal surface distribution before the jet head, the fumarole extend to the jet head rear end and with the annular air cabin intercommunication of jet head rear end, the external gas pipeline of carrying inert gas in air cabin, the jet head outside still overlaps and is equipped with annular brush, the brush hair front end of brush is suddenly in the setting of laser head terminal surface.

Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: : establish the jet head through encircling in the laser head outside, set up annular air cabin in the jet head, make the atmospheric pressure distribution of each fumarole even to let in inert gas in gas line, inert gas not only can cool off the cutting area of laser cutting head after getting into the jet head, and inert gas can also completely cut off oxygen simultaneously and stop the burning, and the splash drops back door leaf surface just can not adhesion at once like this, then in time clears up it with the brush and can clear away it, does not influence the cutting again simultaneously.

Preferably, the device also comprises a cover shell which covers the laser head, the gas spray head and the annular hairbrush. Not only can protect the operator, but also can reduce the area of the splashed objects falling.

Furthermore, the housing is symmetrically provided with a dust suction hole which is connected with the dust collector through a dust suction pipe. The cooled splashes can be directly subjected to dust collection treatment, and the splashes falling to the surface of the door leaf are reduced.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

the invention will be further explained with reference to the drawings and the detailed description below:

as shown in fig. 1, a people's air defense door laser cutting device, including laser head 1 that is used for laser cutting, still establish the ring type fumarole 2 in the laser head outside including the cover, a plurality of fumaroles 3 of 2 preceding terminal surface evenly distributed of fumarole, fumarole 3 extend to the fumarole rear end and with the annular air cabin intercommunication of fumarole rear end, the external gas pipeline 5 of carrying inert gas in air cabin, deliver to the fumarole with inert gas through gas pipeline in, 2 outside covers still of fumarole are equipped with annular brush 4, the brush hair front end of brush 4 is suddenly in the setting of laser head terminal surface. Preferably, the device also comprises a cover 6 which covers the laser head, the air nozzle and the annular hairbrush, and the cover 6 is also symmetrically provided with a plurality of dust suction holes which are connected with a dust collector through a dust suction pipe 7.

During the use, when laser cutting, inert gas passes through the gas pipeline and gets into the gas nozzle, cools down the splash, and simultaneously, the dust absorption hole on the housing adsorbs refrigerated splash, inhales it in the dust catcher, reduces the flying dust that falls back on the door leaf, then closes the laser head, utilizes the brush to clear away the flying dust that falls back to the regional surface of cutting, avoids its adhesion on the regional surface of cutting again.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
