Abstract
The invention provides a laser cutting machine by taking compressed air as auxiliary gas. The laser cutting machine comprises a laser cutting head, and a laser generator and auxiliary equipment which are connected with the laser cutting head; and the laser cutting machine is characterized by also comprising an air compressor, wherein a gas pipeline is connected with the air compressor and the laser cutting head; and an air filter is arranged at a joint of the interior of the air compressor and the gas pipeline. By the device, the defects in the prior art are overcome, the compressed air is utilized to replace the traditional nitrogen and oxygen and serves as the auxiliary gas, the production cost is greatly reduced, and the laser cutting machine is reliable in quality and convenient to operate.
Description
Technical field
The present invention relates to a kind of is the laser cutting machine of assist gas with compressed air, belongs to the laser cutting machine technical field.
Background technology
The operation principle of laser cutting machine is: laser beam is radiated at material surface to be cut through laser cutting head; Reach melting state behind the absorbed heat to be cut; The liquid material that assist gas will melt again blows away; The fusing point zone produces continuous joint-cutting along with cut direction progressively moves, and accomplishes laser cutting process.
At present the assist gas that uses of laser cutting machine is generally the nitrogen that oxygen that the carbon steel material uses and cutting stainless steel, aluminium alloy, brass material are used.Oxygen and nitrogen all need to be purchased from air feed aperiodically to buy, and is with high costs, nitrogen especially, and per hour the cutting gas expense is approximately 155 yuan, lets a lot of processing producer feel more pressure.
Summary of the invention
The purpose of this invention is to provide a kind of laser cutting machine that can significantly reduce production costs.
In order to achieve the above object; It is the laser cutting machine of assist gas with compressed air that technical scheme of the present invention provides a kind of; Comprise laser cutting head; Laser generator all is connected with laser cutting head with auxiliary equipment, it is characterized in that: also comprise air compressor machine, gas pipeline connects air compressor machine and laser cutting head; Air compressor machine is inner to be provided with air cleaner with the gas pipeline junction.
Preferably, the compressed air pressure value that provides of said air compressor machine is 0.5～8Bar.
Provided by the invention a kind of be the laser cutting machine of assist gas with compressed air; Utilize compressed air to replace traditional nitrogen and oxygen as assist gas; Buy because of oxygen and nitrogen all need be purchased from air feed, and compressed air can directly freely obtain from nature, has significantly reduced production cost; A large amount of evidences, the assist medium when compressed air can be used as Laser Processing, and work quality is reliable; Cutting technique is constant, and is easy to operate.
Device provided by the invention has overcome the deficiency of prior art, utilizes compressed air to replace traditional nitrogen and oxygen as assist gas, has significantly reduced production cost, reliable in quality and easy to operate.
Description of drawings
Fig. 1 for provided by the invention a kind of be the laser cutting machine sketch map of assist gas with compressed air.
The specific embodiment
For making the present invention more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
Fig. 1 for provided by the invention a kind of be the laser cutting machine sketch map of assist gas with compressed air, described a kind of be that the laser cutting machine of assist gas is made up of laser generator 2, auxiliary equipment 3, laser cutting head 4, gas pipeline 5, air compressor machine 6 and air cleaner 7 with compressed air.
Except containing 78% nitrogen and 21% oxygen, also comprising many rare gas and impurity in the air, is to remove impurity, with gas pipeline 5 junctions air cleaners 7 is installed in that air compressor machine 6 is inner.
Device provided by the invention has been practiced thrift cost greatly; Still according to normal technology cutting, laser cutting head 4 is radiated at material to be cut 1 surface with laser beam during cutting, reaches melting state after material 1 to be cut absorbs heat; The compressed air that air compressor machine 6 provides gets into laser cutting head 4 through gas pipeline 5 again after filter 7 filtration treatment; The liquid material that the clean air that contracts will melt blows away, and the fusing point zone produces continuous joint-cutting along with cut direction progressively moves, and accomplishes laser cutting process.
Provided by the invention a kind of with compressed air be assist gas laser cutting machine with common be that the laser cutting machine of assist gas is compared with oxygen or nitrogen; Only need to increase air compressor machine 6 and gas pipeline 5; Only need the electricity charge during use; Itself approaches zero cost cutting gas, and the long-term production benefit is considerable, and estimation is as follows roughly:
The oxygen of (1) 1 bottle of 165L carbon steel sheet material matter continuously is about 2280 fens about (38 hours); 1 bottle of 165L oxygen price is 400 yuan; Cut with compressed air; Per hour approximately can practice thrift 10 yuan of gas fees after removing the electricity charge, calculate according to 12 hours in one day and can practice thrift 120 yuan/day of gas fees (the lathe operation of general processing factory all is more than 16 hours), reducing expenses in one month is about: 23 days=2760 yuan of 120 yuan of/day *.
The nitrogen of (2) 1 bottles of 165L is about 150 minutes of cutting stainless steel material (2 hours 30 minutes) continuously, and 1 bottle of 165L nitrogen price is 390 yuan.With the compressed air cutting, per hour approximately can practice thrift 130 yuan of gas fees except that after the electricity charge.Calculated according to 12 hours in one day and can practice thrift 1560 yuan/day of gas fees (the lathe operation of general processing factory all is more than 16 hours), reducing expenses in one month is 23 days=35880 yuan of 1560 yuan of/day *.
From the above, it is considerable that device provided by the invention is processed the appropriate litigation fees that adds up saving for many years.
Claims (2)
1. one kind is the laser cutting machine of assist gas with compressed air; Comprise laser cutting head (4); Laser generator (2) all is connected with laser cutting head (4) with auxiliary equipment (3), it is characterized in that: also comprise air compressor machine (6), gas pipeline (5) connects air compressor machine (6) and laser cutting head (4); Air compressor machine (6) is inner to be provided with air cleaner (7) with gas pipeline (5) junction.
2. as claimed in claim 1 a kind of be the laser cutting machine of assist gas with compressed air, it is characterized in that: the compressed air pressure value that said air compressor machine (6) provides is 0.5～8Bar.
