Description
Technical field
The present invention relates to a kind of method of recombination laser cleaning, in particular to a kind of recombination laser cleans metal material surface
The method of thicker substance.
Background technique
Optical-fiber laser cleaning metal material surface substance traditional at present mainly uses: in the cleaned head of single fiber laser beam
Optical system vaporizes after converging to metal material surface rusty scale it being made to absorb laser, and cleaning head absorbs vaporization substance, mobile cleaning
Head realizes the cleaning of metal material surface rusty scale, and in this manner, metal material surface is lower to laser induced plasma flow field, only
Laser energy can be absorbed in relatively thin rusty scale, and cleaning rusty scale thickness utmostly also only has 0.2mm, it is thicker to be unable to cleaning material surface
Rusty scale substance, can only repeatedly for the thicker substance of removing and slower speed is cleaned, but due to metal material surface substance pair
Laser absorption rate is lower, and thicker substance laser cleaning is applied and can not also be solved with upper type.Therefore traditional laser cleaning metal
The method of material surface limits its ability for cleaning the thicker substance of metal material surface.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned problems of the prior art, and provide a kind of side of recombination laser cleaning
Method, a kind of wavelength laser of the invention preheat metal material surface rusty scale, increase suction of the material surface rusty scale to laser
It produces effects rate, another wavelength laser evaporated metal material surface rusty scale, mobile cleaning head makes focal beam spot along metal material surface
Straight reciprocating motion, until entire cleaning process, to realize that metal material surface rusty scale reaches the cleaning of 0.5mm thickness.
The technical solution of the present invention is as follows:
A kind of method of recombination laser cleaning, it is characterised in that sequentially include the following steps:
(1), the cleaned head inner optical system of two kinds of different wave length laser converges to metal material surface, and material surface is made to become rusty
Layer vaporizes after absorbing laser；(2), cleaning head absorbs gasification substance；(3), mobile cleaning head cleans metal material surface substance.
Two kinds of different wave length laser are respectively 915nm wavelength laser and 1080nm wavelength laser.
The focal beam spot of the 915nm wavelength laser and 1080nm wavelength laser coaxially acts on metal material table simultaneously
Face, 915nm wavelength laser preheat metal material surface rusty scale, increase rusty scale to laser induced plasma flow field, 1080nm wave
Long laser vaporization metal material surface rusty scale, mobile cleaning head make focal beam spot along metal material surface straight reciprocating motion, directly
To entire cleaning process, to realize that metal material surface rusty scale reaches the cleaning of 0.5mm thickness.
The mobile cleaning head of the present invention makes focal beam spot along metal material surface straight reciprocating motion, until entirely cleaning
Journey, to realize that metal material surface rusty scale reaches the cleaning of 0.5mm thickness rusty scale.
Detailed description of the invention
Fig. 1 is the schematic diagram that the present invention cleans thick metal material.
Specific embodiment
In conjunction with attached drawing, the invention will be further described.
As shown in Figure 1, sequentially include the following steps: (1), 915nm wavelength laser and 1080nm wavelength laser of the invention mixes
The cleaned head inner optical system of the laser beam of conjunction converges to metal rust plate surface, and 915nm wavelength laser is to metal rust plate surface rust
Layer is preheated, and increases rusty scale to laser induced plasma flow field, 1080nm wavelength laser evaporated metal material surface rust rusty scale makes gold
Belong to after rust plate surface rusty scale absorbs laser and vaporizing；(2), cleaning head absorbs gasification substance；(3), mobile cleaning head makes focal beam spot
Along metal rust plate surface straight reciprocating motion, cleaning head and metal rust plate relative movement, until entire cleaning process, to realize
The cleaning of metal rust plate surface 0.5mm thickness rusty scale.The structure of cleaning head of the present invention is existing structure.
