Description

A kind of laser cutting air blowing structure, laser cutting device and its cutting head
Technical field
The utility model relates to laser cutting device, more specifically a kind of laser cutting air blowing structure is swashed using this Light cuts the laser cutting device of blowing structure and the cutting head of laser cutting device.
Background technique
There is rifling in the gun tube of artillery, shell rotation can be made to increase the speed and rectilinear flight of shell, after typhoon generates, The pressure and speed of its center eye of wind are maximum, in laser cutting, in order to obtain better cutting effect, quality and speed, need Will during cutting blowing, it is both uneconomical or do not save energy consumption so the consumption of gas is larger in processing, in present society Under the background of the energy-saving and emission-reduction of meeting, how to reduce energy consumption as far as possible, be the direction that everybody pursues and make great efforts always.
Summary of the invention
The purpose of the utility model is to provide a kind of laser cutting air blowing structure, laser cutting device and its cutting head, So that obtaining bigger gas outlet air pressure under conditions of same gas supply and concentrating air-flow more.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of laser cutting air blowing structure, the laser cutting air blowing structure include the support of cutting head, the cutting head Pipe and the focusing device that the support tube rear end is set, the cutting head, support tube and the coaxial setting of focusing device, institute The tube wall for stating support tube is provided with air inlet, and the mouth of the cutting head constitutes gas outlet, the inner wall of the support tube and/or institute The inner wall for stating cutting head is provided with spiral grooves.
Preferably, the quantity of the spiral grooves of the support inside pipe wall is one or more.
Preferably, the quantity of the spiral grooves of the cutting head inner wall is one or more.
Preferably, the cutting head is removably installed in the front end of the support tube by bindiny mechanism.
A kind of laser cutting device, the laser cutting device include cutting work head, and the cutting work head includes upper State laser cutting air blowing structure described in any one.
The mouth of a kind of cutting head of laser cutting device, the cutting head constitutes gas outlet, the inner wall of the cutting head It is provided with spiral grooves.
Compared with prior art, the utility model at least has the advantages that
Air pressure due to being provided with above-mentioned spiral grooves, gas outlet significantly increases, and more concentrates after gas outflow.
Detailed description of the invention
Fig. 1 is sectional view of the exemplary embodiments laser cutting air blowing structure along axis;
Fig. 2 be its along Fig. 1 A-A to sectional view;
Fig. 3 is the sectional view of its B-B direction along Fig. 1;
Fig. 4 is the sectional view of exemplary embodiments cutting head.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
Referring to figs. 1 to Fig. 3, exemplary embodiments laser cutting air blowing structure includes the branch of cutting head 10, the cutting head 10 Stay tube 20 and the focusing device 30 that 20 rear end of support tube is set, the cutting head 10, support tube 20 and focusing device 30 coaxial settings, the tube wall of the support tube 20 are provided with air inlet 21, and the mouth 11 of the cutting head 10 constitutes gas outlet, institute The inner wall for stating support tube 20 is provided with the first spiral grooves 22, and the inner wall of the cutting head 10 is provided with the second spiral grooves 12.
When work, on the one hand, laser exposes to after the focusing device 30 focusing from the mouth 11 of the cutting head 10 On workpiece 40, on the other hand, gas enters from the air inlet 21 of 20 tube wall of support tube, then from the gas outlet (mouth of cutting head 10 Portion 11) blow on workpiece 40 by cutting part.
Above-described embodiment is by increasing by the first spiral grooves 22, second in the inner wall of support tube 20 and the inner wall of cutting head 10 Spiral grooves 12.Compared to existing structure, under conditions of same gas supply, the gas outlet (mouth of cutting head 10 of above-described embodiment Portion 11) bigger gas outlet air pressure is obtained, and also air-flow is more concentrated.
As one embodiment, the first spiral grooves 22, i.e., the quantity of the spiral grooves of described 20 inner wall of support tube are one Item.
As another embodiment, the quantity of the first spiral grooves 22, i.e., the spiral grooves of described 20 inner wall of support tube is It is a plurality of.
There are also in a kind of embodiment, the second spiral grooves 12, the quantity of the spiral grooves of 10 inner wall of cutting head is one Item.
There are also in embodiment, the second spiral grooves 12, the quantity of the spiral grooves of 10 inner wall of cutting head is a plurality of.
Further, it is also possible to which spiral grooves only are arranged in the inner wall of support tube 20, can also only be arranged in the inner wall of cutting head Spiral grooves.
For the ease of replacing the cutting head of different size, the cutting head 10 is by bindiny mechanism, such as screw thread, detachably Ground is installed on the front end of the support tube 20.
A kind of laser cutting device, the laser cutting device include cutting work head, and the cutting work head includes upper The laser cutting air blowing structure stated.
Referring to Fig. 4, the mouth 11 of the cutting head 10 of exemplary embodiments laser cutting device constitutes gas outlet, the cutting head 10 inner wall is provided with spiral grooves 12.
The utility model is described in detail above by specific embodiment, these detailed description are only limited to The content of the utility model is helped skilled in the art to understand, the limit to scope of protection of the utility model can not be interpreted as System.Those skilled in the art should all wrap various retouchings, the equivalent transformation etc. that above scheme carries out under the utility model design Containing within the protection scope of the present utility model.
