Abstract
The invention relates to a cladding head with pollution prevention function of focusing device; the cladding head comprises optical fiber interfaces coaxially connected and arranged, a focusing device and a powder discharging mechanism provided with a powder outlet; the cladding head is characterized in that the focusing device is coaxially provided with an air feed pipe by a connection piece; the bottom of the air feed pipe is bent to be vertically arranged and corresponding to the powder outlet. The cladding head has simple structure, reasonable design, reliable performance and obvious application effect; the bottom of the air feed pipe is provided with a transverse air flue to blow away sputtering objects crossly and prevent the sputtering objects from entering into the inner part of the cladding head; the work situation of the optical part can be greatly improved, thereby reducing the loss of protective lenses and the maintenance time for cladding head, and effectively improving the work efficiency. The cladding head effectively ensures stable operation of processing device and also can improve the quality of processing products.
Description
Technical field
The present invention relates to a kind of cladding head, particularly a kind of have a protection focalizer antipollution cladding head.
Background technology
At present, the cladding head of using in the laser construction, cladding head are subjected to following sputter thing in the course of the work easily and pollute, and easily cause protective glass to burst; Directly the progress of engineering and the quality of product processing are implemented in influence.
Specifically, optical fiber laser light-emitting window place is the optical fiber cladding head, and in use, metal powder Stimulated Light irradiation fusing combines with workpiece to be machined.Because combine of metal powder and workpiece needs high temperature melting, in this process, can produce zone of oxidation on the cladding layer surface, next time on this cladding layer during cladding, the zone of oxidation meeting spring of being heated is spattered.Because the influence of factors such as material, temperature, cladding thickness, cause the situation of sputter also inequality, the sputter thing can directly crash the protection eyeglass when serious, laser is bent by the protection eyeglass time, and the calcination protective glass produces smog, pollute condensing lens, finally cause laser not export, laser energy can not discharge burning apparatus in cladding head inside; When sputter was light, the sputter thing can adhere on the protection eyeglass, destroys coatings, makes the light transmission variation of protective glass, as untimely replacing, protective glass is burnt, final burning apparatus.
Therefore, providing a kind of simple in structure, reasonable in design, effect to have the antipollution cladding head of protection focalizer significantly, is one of these those skilled in the art problem that should address.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, provide a kind of simple in structure, reasonable in design, effect has the antipollution cladding head of protection focalizer significantly.
The technical solution adopted in the present invention is for achieving the above object: a kind of have a protection focalizer antipollution cladding head, and this cladding head comprises the optical fiber interface that coaxial connection is provided with, focalizer and be provided with the powder delivery mechanism of meal outlet; It is characterized in that described focalizer by the coaxial induction pipe that is provided with of web member, described induction pipe bottom is bent into vertically to setting and corresponding with meal outlet.
The invention has the beneficial effects as follows: this cladding head is simple in structure, reasonable in design, dependable performance, effect highly significant; One horizontal air channel is formed on the induction pipe bottom that is provided with, and the sputter thing is laterally blown away, and does not make it enter cladding head inside; Improved the working condition of opticator greatly, reduced the loss of protection eyeglass, and reduced maintenance time, effectively increased work efficiency cladding head.The present invention not only effectively guarantees the steady running of processing units, also can improve the quality of converted products.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1 optical fiber interface, 2 focalizers, 3 powder delivery mechanisms, 4 tracheaes, 5 web members.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to embodiment provided by the invention, structure, details are as follows for feature:
As shown in Figure 1, a kind of have a protection focalizer antipollution cladding head, and this cladding head comprises the optical fiber interface 1 that coaxial connection is provided with, focalizer 2 and be provided with the powder delivery mechanism 3 of meal outlet; It is characterized in that described focalizer 2 by the web member 5 coaxial induction pipes 4 that are provided with, described induction pipe 4 bottoms are bent into vertically to setting and corresponding with meal outlet.
The present invention is applicable to the protection of the optics at optical fiber laser light-emitting window place, wants to use safely the laser melting coating head, must solve the pollution problem of sputter thing to protective glass.
Design of the present invention is the induction pipe by being provided with; more than the following metal powder of the laser exit of laser melting coating head, form an air curtain perpendicular to laser beam; the sputter thing is moved perpendicular to beam direction; so; the sputter thing just was blown away before touching protective glass; no longer the contact protection mirror has guaranteed the cleaning of protective glass, makes production smooth.This air curtain has no effect to laser beam simultaneously, the more unnecessary heat of cladding head can be taken away, and plays air-cooled effect.Because far away apart from metal powder, also very little to the influence of powder, can meet the needs of production fully.In actual use, the air curtain production well is made the finedraw of 0.5mm * 15mm, increase air pressure (1MPa) effect more.
In the enforcement, induction pipe 4 can carry out position adjustments by web member 5, makes its bottom form a horizontal air channel, and the sputter thing is laterally blown away, and is clean anti-pollution, guarantees that effectively this cladding head is safe and reliable to operation.Through using proof, effect highly significant.
Above-mentioned have the detailed description that the antipollution cladding head of protection focalizer carries out with reference to embodiment to this, is illustrative rather than determinate; Therefore in the variation and the modification that do not break away under the general plotting of the present invention, should belong within protection scope of the present invention.
