Description
One, technical field
The invention belongs to a kind of process and the laser cutting head unit thereof that compressed air is used for laser cut metal tubing that relates in the laser application technique field.
Two, technical background
When metal pipe material is carried out Laser cutting, understand phenomenons different when producing some with planar metal sheet material work piece cut, because the architectural feature of metal pipe material, when laser cutting, inevitably the slag that produces is sprayed on the inner surface of tubing otch opposite side, cause the local temperature of tubing workpiece to rise rapidly, particularly for the less tubing of diameter, fuel factor is more obvious, can directly cause the decline of laser cutting quality, even can't continue cutting.Therefore, how solving metal pipe material hot-spot problem in the laser cutting process, is to improve the problem that the laser cutting quality must be considered.
The present invention in the past, with solving the overheated problem of laser cut metal tubing, have plenty of the way of employing to metal pipe material inside water flowing cooling, the method is all right to the less tubing of diameter, but for diameter greater than the tubing commonly used more than the 10mm, because water consumption is bigger, and environmental pollution is serious, implements very difficult.The prior art the most approaching with the present invention is " its cold process of supercharging " that is proposed by Switzerland hundred super laser Co., Ltds (BYSTRONIC) the earliest, and this kind method is to realize by the method that strengthens auxiliary cutting oxygen air pressure in cutting process.As shown in Figure 1, laser cutting head integral body comprises condenser lens 1, laser cutting head 2, oxygen jet 3, processed cut workpiece 4.Condenser lens 1 places in the laser cutting head 2, and the oxygen spray direction is identical with the laser beam transmit direction and coaxial, and oxygen and laser beam penetrate from oxygen jet 3 simultaneously, directly be mapped to vertical with laser beam, on the workpiece to be machined 4 of horizontal positioned.Usually the oxygen that cutting is used to flat work pieces is pressed, and generally about 0.2MPa, adopts the way that strengthens oxygen, oxygen pressure can be increased to 0.8MPa.After strengthening the oxygen pressure, oxygen had both played the effect of auxiliary laser cutting, had the effect that cooling is cut workpiece again, solved the hot-spot problem of metal pipe material in laser cutting process.Yet this process, oxygen consumed tolerance are 4-5 times of common cuts sheet material consumption, the expense costliness, and owing to be to work under condition of high voltage, condenser lens easily produces distortion even damages, must consider relevant safeguard procedures when therefore designing, also increase corresponding manufacturing cost or the like.
Three, summary of the invention
In order to overcome the shortcoming that prior art exists, the hot-spot problem that produces on the workpiece when the objective of the invention is to prevent the metal pipe material cutting effectively, thereby improve the laser cutting quality, reduce simultaneously the cost of laser cutting again greatly, reduce and pollute a kind of process and laser cutting header structure thereof that compressed air is used for laser cut metal tubing of ad hoc meter.
The technical problem to be solved in the present invention is: a kind of process and laser cutting head unit thereof that compressed air is used for laser cut metal tubing is provided.The technical scheme of technical solution problem is realized that by laser cutting head unit shown in Figure 2 the laser cutting head unit comprises condenser lens 5, laser cutting head 6, oxygen jet 7, the workpiece 8 that is cut, shower nozzle adjusting support 9, compressed air shower nozzle 10, compressed-air atomizer 11.
The process that compressed air is used for laser cut metal tubing is: compressed air is introduced laser cutting parameter, on general laser cutting head, shower nozzle is installed is regulated support 9, compressed air shower nozzle 10 being installed in shower nozzle regulates on the support 9 again, adjust shower nozzle adjusting support 9 and can change distance and the angle of compressed air shower nozzle 10 with respect to oxygen jet 7, and compressed-air atomizer is with respect to the distance that is cut workpiece, carry out before the laser cutting, the angle of at first regulating between compressed air shower nozzle 10 and the oxygen jet 7 is 40 ° of-50 ° of angles, compressed-air atomizer 11 is 15-25mm to the distance of oxygen jet 7, air gun 11 is 6-10mm to the distance of the workpiece 8 that is cut, and accomplishes to make compressed air shower nozzle 10 and oxygen nozzle 7 to be synchronized with the movement.Oxygen presses the oxygen that adopts common laser cutting flat sheet to press, be about 0.2MPa, the compressed-air actuated air pressure of connecting is 1.5～2.5 times that oxygen is pressed, is about 0.3～0.5Mpa, send oxygen during cutting earlier, after send compressed air, open laser instrument emission laser again, cut when finishing, at first the closes compression air, stop to launch laser, close oxygen again.
In the laser cutting head unit shown in the figure two, condenser lens 5, laser cutting head 6, oxygen jet 7 have constituted general laser cutting head, condenser lens 5 places laser cutting head 6, the injection of oxygen is in the same way coaxial with the laser beam transmit direction, and the emitted laser bundle is vertical with the workpiece to be machined 8 of horizontal positioned.Shower nozzle is housed at the position on the upper side of laser cutting head 6 regulates support 9, rigidity connects firmly between the two, on shower nozzle adjusting support 9, compressed air shower nozzle 10 is housed, have compressed-air atomizer 11 on the compressed air shower nozzle 10, regulate shower nozzle adjusting support 9 and can regulate the compressed air shower nozzle 10 that is contained on it, compressed-air atomizer 11 and the angle between the oxygen jet 7 on it are changed in 40 ° of-50 ° of scopes, compressed-air atomizer 11 changes in the 15mm-25mm scope to the distance of oxygen jet 7, and compressed-air atomizer 11 changes in the 6mm-10mm scope to the distance that is cut between the workpiece 8.
Good effect of the present invention: using under the oxygen pressure of conventional laser cutting metal flat sheet, the technology that compressed air is used for laser cut metal tubing, compare with simple increasing oxygen pressure, saved a large amount of oxygen consumptions, reduced the laser cutting cost, pressure is that the compressed air that 1.5-2.5 times of oxygen is pressed directly blows to the surface that is cut metal pipe material, reduced effectively and be cut near the temperature in place, thereby the hot-spot problem that has produced on the workpiece when having prevented the metal pipe material cutting, and then improved the laser cutting quality.
