Abstract
The utility model discloses a laser carving machine, which includes a laser (8) and a gas nozzle (2) on output path. One end of the gas nozzle (2) is provided a window (10) and the other end is a spout (6) on the same axle with the laser (8) path. The lateral side of the gas nozzle (2) is connected with a gas pipe (11). Particularly, the gas pipe (11) is connected with air or oxygen source (1), the pressure of which is 0.1-0.3MPa; the inner wall of the spout (6) is in cylinder shape, with the diameter of 1.2-3 mm, length of 1-8 mm; oxygen in oxygen source (1) takes up 60 per cent of the total volume; the path between the laser (8) and the gas nozzle (2) is arranged with a reflecting mirror (9). The utility model can improve the carving efficiency, obtain smooth and rounded carving surface, decrease the temperature of non-metal material carved quickly, reduce the deformation and internal stress of the caring object and also can be widely used in fine carving field of non-metal material.
Description
Technical field the utility model relates to a kind of engraving equipment, especially laser engraving machine.
Background technology is present, and people often use laser engraving machine in order to carry out meticulous engraving on various nonmetallic materials.The mechanism of its engraving mainly is to utilize the interaction of the luminous energy and the material to be processed of laser, makes the luminous energy of laser be transformed into heat energy, vaporizes or melts away material to be processed, to form needed figure or profile.Laser engraving machine is mainly by laser and the gas tip that is serially connected on its output light path, and corresponding servicing unit constitutes, wherein, gas tip is the hollow body that waits wall thickness, the window that its two ends are respectively the transmission laser bundle with the gas spout of the light path coaxial of laser, side tracheae for being connected with air pump below the output pressure 0.04Mp, servicing unit for fixing material to be processed, be subjected to computer-controlled three-dimensional compliant platform.During engraving, computer is controlled the output facula that three-dimensional compliant platform is followed laser according to figure to be processed, carves so that laser beam is treated rapidoprint; In the process of engraving, carving area internal cause engraving and the dirt bits that produce are brushed it fall by gas tip in time.But the efficient that this engraving machine exists engraving is not high, easily treat the deficiency that material processed causes hidden defect.
The summary of the invention the technical problems to be solved in the utility model provides a kind of simple in structure, practical laser engraving machine for overcoming weak point of the prior art.
The technical scheme that is adopted comprises the gas tip on laser and its output light path, one end of said gas tip is that window, the other end are the spout coaxial with laser light path, the side of gas tip is connected with tracheae, particularly said tracheae is connected with the air or oxygen source, the pressure in said air or oxygen source is 0.1～0.3Mp, the inwall of said spout is cylindric, and its diameter is that 1.2～3mm, length are 1～8mm.
As the further improvement of technical scheme, the oxygen in the described source of oxygen accounts for 60% of its cumulative volume; Be equipped with speculum on the light path between described laser and gas tip.
Beneficial effect with respect to prior art is, one, the pressure-air of the spout of gas tip ejection or oxygen and just by the oxidation reaction that produces between the nonmetallic materials of laser radiation, the vaporization or the fusing process of laser have been quickened, the irradiation time of laser beam has been shortened widely, improved the efficient of engraving, through actual measurement, effect has improved nearly five times; Its two, the gas line that columned spout produces is chiseled and carved the souring at place to the nonmetallic materials of being carved, and makes its smooth surface, mellow and full; Its three, the washing away by force of gases at high pressure line promptly reduced the temperature of the nonmetallic materials of being carved, and reduced its deformation and internal stress.
Description of drawings is described in further detail optimal way of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a kind of basic structure schematic diagram of the present utility model.
Embodiment is equipped with speculum 9 and gas tip 2 successively referring to Fig. 1 on the output light path of laser 8, wherein, the side of gas tip 2 is connected tracheae 11, and this tracheae 11 is connected with source of oxygen 1, and the air pressure of source of oxygen 1 is 0.15Mp; One end of gas tip 2 is that the window 10, the other end of the laser beam 7 of transmissive laser 8 output is the spout 6 coaxial with laser beam 7, and the inwall of spout 6 is cylindric, and its diameter is that 2mm, length are 5mm.
During use, at first open source of oxygen 1, make high pressure oxygen form hyperbaric oxygen air flow stream 3, and spray to chiseling and carving of material to be processed (acrylic plate) 5 and locate 4 from spout 6 places of gas tip 2; Then make laser 8 work, laser beam 7 directives material 5 to be processed is chiseling and carving place 4 and 3 interactions of hyperbaric oxygen air flow stream, to finish incised work.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
