Description
Technical field
The invention belongs to technical field of laser processing, and in particular to a kind of magnetic field auxiliary based on existing laser process equipment
Laser polishing device.
Research background
Laser processing technology is most potential one of advanced manufacturing technology at present, because laser have monochromaticjty, coherence,
A series of incomparable advantage of common light waves such as directionality, high-energy density, laser processing have been widely used in aviation
The fields such as space flight, automotive electronics, energy source and power and biologic medical, laser processing technology gradually develop into 21st century
One of significant technology.
For laser polishing as a kind of emerging one of laser processing technology, it acts on gold using high energy beam laser as heat source
After on category or nonmetallic materials, material absorbs laser energy and causes temperature to increase, melt or vaporization, in gravity and surface tension
Under, the recessed surface of filling material realizes the polishing shaping processing of various rough surfaces, reduces the coarse of material surface with this
Degree.Compared with traditional machinery, electrochemical polish, laser polishing have it is non-contact, can microcell, can constituency, without mechanically and chemically
The advantages such as damage, pollution-free and environment-friendly high-efficiency.In recent years, BJ University of Aeronautics & Astronautics, the Central China University of Science and Technology, Belgium Lu Wen great
, Coventry, United Kingdom manufacturing technology center, Nantes, France communication and control research institute, Birmingham, GBR university, Hong Kong science and engineering are big
The domestic and international research institution such as has reduced the surface roughness of all kinds of metal/non-metal parts using laser polishing technology.
However these laser polishing methods are all on existing nanosecond optical fiber, quasi-molecule or semiconductor laser at present
Laser polishing is directly carried out, due to originals such as molten bath is splashed, cooling temperature is uneven, big, the polished part geomery complexity of polishing area
Cause, the defects of being easy to produce crackle, uneven ripple protrusion, overlap joint striped, stomata, it usually needs be aided with some special additional
Technological means reduces the generation of such defect.Existing research shows that externally-applied magnetic field can effectively influence in laser processing procedure
Molten bath flowing, heat transfer and plasma the direction of motion, can not only promote melt cooling procedure in crystal nucleation and crystal
The process of growth, and the crystalline structure of metal bath can be made to refine, crackle between compound and crystal between inhibition molten metal
Generation, improve its mechanical property.Based on the above advantages, magnetic field secondary process technology laser welding, laser melting coating,
The fields such as laser drill are widely applied, but relatively fewer for the technique study of externally-applied magnetic field auxiliary laser polishing, and
It is immature, it is concentrated mainly on the experimental stage in laboratory.Such as: Zhejiang Polytechnical University's laser processing technology Engineering Research Center
Experts and scholars once used steady magnetic field auxiliary the inhibiting effect of laser melting layer surface ripple is studied, by experiment and
The mode of numerical simulation demonstrates externally-applied magnetic field can generate inhibiting effect to the uneven ripple protrusion of molten metal surface, but
The specific magnetic field device used has a single function and the distance between two coils do not have controllability.
Importantly, polished workpiece often has sizes, and complex-shaped in laser polishing process,
The applying mode of existing externally-applied magnetic field, cannot generally all by magnet exciting coil, permanent-magnet pole or the field generator for magnetic of fixation
For the distance between two field coils of dissimilar metal flexible modulation, magnetic field strength is made to reach requirement, although for ruler
Very little small, simple shape workpiece can be convenient use, but for size for big, complex-shaped workpiece, such magnetic field is auxiliary
Help device not only clumsy, it is poor for applicability, and also the magnetic field strength between two opposite field coils is difficult to accomplish optimal tune
Effect is saved, causes externally-applied magnetic field to be extremely difficult to ideal state to the control in molten bath, can not fundamentally solve laser polishing mistake
In journey the problems such as molten bath splashing, crackle, stomata, raised uneven ripple.
Therefore a kind of simple process is researched and developed, polishing efficiency is high, high degree of automation, and can inhibit to produce in laser polishing process
Raw uneven ripple protrusion, reduces metal component surface roughness, and magnetic field auxiliary is realized on existing laser process equipment
The device of laser polishing becomes current researcher urgent problem to be solved.
