Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of laser cutting method, is intended to solve existing cut and adopts oxygen or nitrogen as assist gas, the problem that cost is high.
The embodiment of the invention is achieved in that a kind of laser cutting method, may further comprise the steps:
The compression, the formation assist gas purifies air;
Make said assist gas get into cutting head;
According to workpiece material and specification, corresponding technological parameter is set, make the coaxial workpiece that exports to of said assist gas and laser beam, said workpiece moves until cutting with respect to said cutting head and finishes.
Another purpose of the embodiment of the invention is to provide a kind of laser cutting machine; The cutting head that comprises laser instrument and the laser beam that receives said laser instrument generation; Said laser cutting machine also comprises the air accumulator of the air compressor machine that compresses outside air, store compressed air and purifies said compressed-air actuated air cleaner; Said compressed air purifies through said air cleaner and forms assist gas, and said assist gas gets into said cutting head through tracheae.
The embodiment of the invention has greatly reduced production cost with compression, the air that the purified assist gas as cut, saves time of exchanging gas, has improved production efficiency, and reliable in quality.
Description of drawings
Fig. 1 is the realization flow figure of the laser cutting method that provides of the embodiment of the invention;
Fig. 2 is the structural representation of the laser cutting machine that provides of the embodiment of the invention.
The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The embodiment of the invention has greatly reduced production cost with compression, the air that the purified assist gas as cut, saves time of exchanging gas, has improved production efficiency, and reliable in quality.
Below in conjunction with specific embodiment realization of the present invention is described in detail.
Fig. 1 shows the realization flow of the laser cutting method that the embodiment of the invention provides, and details are as follows:
In step S101, the formation assist gas compresses, purifies air;
As shown in Figure 2, through air compressor machine 1 air is compressed in the air accumulator 2 earlier, make the air pressure in the air accumulator 2 remain on 1.0Mp-2.0Mp, must not be lower than 0.8Mp, the air compressor machine of preferred big pressure is stablized supply gas pressure to guarantee enough air pressure.
Then make compressed air in the air accumulator 2 air cleaner 3 of flowing through, formation assist gas 4 after purifying.In air cleaner 3, being provided with the filter 31 of oil removing, dedusting and removing the drier 32 of aqueous vapor along airflow direction, is to guarantee clean-up effect, and filter 31 and drier 32 are a plurality of.Laser beam 51 is conducted by focusing lens 52 in the cutting head 5, and focusing lens 52 leans on assist gas 4 coolings, thereby the quality requirement of assist gas 4 is high.Compressed air guarantees the light path cleaning through purifying, and has protected cutting machine effectively, makes its normal operation.
In step S102, make assist gas get into cutting head;
Above-mentioned assist gas 4 gets into cutting head 5 through tracheae 6, and wherein the internal diameter of tracheae 6 is 16～22mm, to guarantee good throughput, makes cutting effect consistent.Tracheae 6 is connected with the air duct 53 of cutting head 5 sidewalls, and the gas outlet of this air duct 53 is positioned under the focusing lens 52, avoids air-flow to blow focusing lens 52, is beneficial to the cutting machine steady operation.
In step S103, according to workpiece material and specification, corresponding technological parameter is set, make the coaxial workpiece that exports to of assist gas and laser beam, workpiece moves until cutting with respect to cutting head and finishes.
Technological parameter such as following table that the embodiment of the invention adopts Rofin DC030 8 pairs of panel beatings 7 of type laser instrument (like carbon steel, stainless steel, aluminium alloy) to cut:
Technological parameter such as following table that the embodiment of the invention adopts IPG 2000-YLS 8 pairs of panel beatings 7 of type laser instrument (like carbon steel, stainless steel, aluminium alloy) to cut:
The embodiment of the invention is assist gas 4 with the air, and assist gas 4 passes through cutting head 54 coaxial outputs with laser beam 51, and 1mm-3mm carbon steel, 1mm-6mm stainless steel and 1mm-3mm aluminium alloy are cut, and technological parameter is that last table is listed, and test result is following:
Rofin DC030 type laser instrument cutting 1mm-3mm carbon steel, cutting speed is general; Cutting 1mm-6mm stainless steel rapid speed, cut quality is good; Cutting 1mm-3mm aluminium alloy, cutting speed is very fast, and cut quality is general, but can satisfy the production demand.The speed of IPG 2000-YLS type laser instrument carbon steel is fast, and the quality of cutting stainless steel and aluminium alloy is good.
