Description
Technical field
The present invention relates to a kind of dust exhaust apparatus and thin-wall pipes Laser Micro-Machining device, belong to laser micro-machining technology field.
Background technology
Laser cutting is because technique is simple, speed is fast, have that width of slit is little, cuts parallel degree is good, surface roughness is little, dimensional accuracy is high, workpiece deformation and heat affected area is little, the feature such as mechanical stress and surface damage, can the complex-shaped micro-workpiece of precise cutting, thus become thin-wall pipes micro Process field main machining method.
Laser cutting is moved along line of cut on metal tube by overlapped laser pulse point, inputs the auxiliary fusing cutting of hyperbaric oxygen simultaneously.The material molten gasification of Laser Focusing point place, slag is blown out by high pressure assist gas, and metal pipe-wall forms cutting track.Thin-wall pipes laser cutting have dry cut and wet cut two kinds of techniques, when dry cutting, originally motlten metal steam outwards launched, but it is last, most steam due to sub-cooled, solidify, formation chip can be solidified at material surface, be dispersed in ablation pattern surface surrounding and cutting, make the joint-cutting of cutting rough.When wet cutting, the water smoke of generation also will siphon away in time, otherwise, gather the normal work that a large amount of water smoke can affect laser instrument.If cutting non-metal material, can produce a large amount of flue dust, in order to avoid these flue dust have an impact to crudy, or these flue dust are retained in tubing and cause partial cut bad, and these flue dust also will siphon away timely.
Thin-wall pipes laser micro process have dry cut and wet cut two kinds of techniques, dry cutting process is blown by assist gas in laser and the material zone of action, for removing the disintegrating slag of otch and cooling laser active region.Adopt wet cutting process, apart from outside process gas, also have the water of certain pressure to flow out from tubing, constantly on tubing, cut many mesh along with in cutting process, water can splash to surrounding from these mesh.Existing material-receiving device can not take into account two kinds of processing technologys, namely can only connect dry Pipe Cutting material, or can only connect wet Pipe Cutting material.Minute sized materials in the tube are directly dropped in pulp-collecting box simultaneously, but helpless to large-sized materials in the tube, necessary manual splicing, and manual splicing production efficiency is low, there will be the danger such as personnel damage simultaneously.On the other hand, when the long material of laser cutting will not fall, manual splicing, because support force is unstable, can produces in cut end and rock, affect cut quality.
The laser cutting of thin-wall pipes is moved along line of cut on tubing by overlapped laser pulse point, inputs the auxiliary fusing cutting of hyperbaric oxygen simultaneously.The material molten gasification of Laser Focusing point place, slag is blown out by gas, and metal pipe-wall forms cutting track.Originally melting gas and slag are outwards launched, but finally, most steam all becomes chip, are dispersed in ablation pattern surface surrounding and cutting.The formation of chip destroys outward appearance and the performance of part.It also reduces ablation efficiency, due to the front chip once stayed may block next time scanning time laser beam propagation path.When the tubing of laser cutting Large Diameter Pipeline, the impact that zonule fire damage is brought is little.But need the tubing cutting small caliber in a lot of application, (caliber is generally less than 5mm) can produce heat fast in laser processing procedure, the thermal diffusion of part can produce fire damage, no matter be heat affected area, melt region, double teeming, or dregs, all change micro-structural.Part heat-affected zone compromises the integrality of part, and then obviously reduces processing output.
