Kusanthula kwa kugwiritsa ntchito ukadaulo wokonzanso wa laser cladding pazigawo zolephera zamakina m'migodi

Mu gawo la uinjiniya wa makina a migodi, mikhalidwe yoopsa yogwirira ntchito ikadali vuto lalikulu lomwe limalepheretsa magwiridwe antchito okhazikika a zida. Malo osungiramo migodi pansi pa nthaka ndi ochepa komanso opapatiza, ndipo fumbi lochuluka limawononga malo a zida nthawi zonse. Pakutulutsa msoko wa malasha, kugundana pafupipafupi pakati pa mano odula ndi miyala yolimba ya malasha, kuphatikiza kukangana kwakukulu pakati pa zotumiza zokokera ndi zinthu, kumathandizira kuwonongeka kwa zigawo. Pakadali pano, kuchuluka kwa mchere ndi chinyezi m'madzi a migodi kumayambitsa dzimbiri lalikulu lamagetsi. Izi zimapangitsa kuti pakhale mavuto ambiri monga kuwonongeka kwambiri, kubowoka chifukwa cha dzimbiri, komanso kukanda pamwamba pa zigawo zofunika kuphatikiza mano odulira malasha, mizati yothandizira ya hydraulic ya makina osungiramo migodi, ndi zigawo zotumizira zokokera. Kulephera msanga kwa zigawozi sikungowonjezera nthawi yogwira ntchito kwa zida komanso kumawonjezera kwambiri ndalama zosamalira komanso zoopsa zachitetezo pantchito za migodi.​

Pofuna kuthana ndi vuto lalikululi, kuphatikiza ukadaulo wamphamvu kwambiri wophimba pamwamba pa laser ndi ufa wapadera wa alloy wosasungunuka kwasintha njira zopangira zinthu zatsopano za makina ogwetsa migodi. Pogwiritsa ntchito kuwala kwa laser kokhala ndi mphamvu zambiri ngati magwero otentha, njira yatsopanoyi imayika ufa wa alloy pamalo okonzera zinthu. Pogwiritsa ntchito kuwala kwa laser, tinthu ta alloy timasungunuka ndikulimba mwachangu ndi substrate, ndikupanga chophimba cholimbikitsidwa ndi zitsulo. Njira yosakanikirana iyi imasiyana kwambiri ndi zomangira zachilengedwe monga electroplating ndi spray coating, kuchotsa zoopsa za kuchotsedwa kwa coating pamene akukhazikitsa maziko a zomangamanga kuti zinthu zigwire bwino ntchito.​

Kapangidwe kake ka ufa wapadera wa aloyi wosungunuka wodziyimira pawokha ndi chimodzi mwa zinthu zaukadaulo. Kawirikawiri pogwiritsa ntchito aloyi okhala ndi nickel, iron-based, kapena cobalt ngati matrices, ufa uwu umagawa mofanana tinthu tolimba kwambiri monga WC, Cr₃C₂, ndi TiC. Mwa kuwonjezera zinthu monga Cr, Mo, ndi Si, kulimba kwa aloyi ndi kukana dzimbiri kumakonzedwa bwino. Tinthu tolimba titha kuwonjezera kuuma kwa zokutira ku HRC55-65, kukana bwino kugundana ndi miyala ya malasha ndi kukangana kwa zinthu. Pakadali pano, matrix yolimba imachepetsa katundu wokhudzana ndi kugunda, kuletsa kusweka kwa blister mu zokutira ndikupeza magwiridwe antchito "olimba koma osasweka".​

Mu ntchito zinazake zopangira zinthu, ukadaulo uwu umasonyeza luso lapadera komanso luso. Pa makina odulira malasha ndi mano odulira makina oboola ngalande, pamwamba pa conical ndi malo ofunikira kwambiri polumikizana mwachindunji ndi miyala ya malasha. Ukadaulo wa laser cladding ukhoza kupanga bwino kwambiri 3-5mm wandiweyani wolimbitsa pamwamba pa cone. Tinthu tolimba mu plating timagwira ntchito ngati "zida" kuti tipewe kuwonongeka kwa kudula kwa miyala ya malasha, pomwe matrix yolimba imayamwa mphamvu yokhudza mphamvu, ndikuwonjezera moyo wautumiki ndi nthawi 2-3 poyerekeza ndi zigawo zatsopano pansi pa mikhalidwe yovuta ya geological. Kwa ma conveyor odula omwe amavala zinthu zomwe zimakhala zovuta kuvala monga ma central turfs ndi ma transition turfs, ma laser-clad supplier cloth amachepetsa kwambiri kuwonongeka kwa abrasive panthawi yotumiza zinthu. Ma central turfs omwe poyamba amafunika kusinthidwa miyezi 3-6 iliyonse tsopano amakhala miyezi 12-24 mutakonzanso. Pa mizati yachitsulo chosapanga dzimbiri m'malo osungiramo madzi opangidwa ndi makina opangidwa ndi makina opangidwa ndi makina opangidwa ndi makina opangidwa ndi hydraulic omwe amateteza malo okhala ndi chinyezi komanso fumbi, zigawo zachikhalidwe zoyika chrome zomwe zimatha kuzizira chifukwa cha kukanda zitha kusinthidwa. Zophimba zophatikizika zophimbidwa ndi laser sizimangochotsa zophimba zowononga komanso zimapirira kuwonongeka kwa kukangana panthawi yokulitsa/kupindika kwa mizati, zomwe zimawonjezera nthawi yokonza nthawi zopitilira kanayi. Pa magiya olephera ndi zida zonyamula mabenchi mu makina otumizira magiya, ukadaulo wa laser cladding umabwezeretsa kulondola kwa mawonekedwe kudzera mu zophimba pomwe ukukonzanso zinthu kuti ziwonjezere kukana kutopa, ndikuwonetsetsa kuti magiyawo amagwira ntchito bwino. Ikani kuti izigwira ntchito.

Poyerekeza ndi njira zachikhalidwe zosinthira zigawo, ukadaulo wokonzanso zinthu pogwiritsa ntchito laser sumangowonjezera moyo wa zinthu zofunika kwambiri nthawi 2-4 komanso umathandizira kubwezeretsanso bwino zinthu zomwe sizinagwiritsidwe ntchito, zomwe zimachepetsa kwambiri kufunikira kwa zinthu zatsopano zomwe zimagwiritsidwa ntchito mumigodi. Deta ikuwonetsa kuti ukadaulo uwu umachepetsa nthawi yogwira ntchito yokonza makina ndi 60% ndipo umachepetsa ndalama zokonzera pachaka ndi 30%-50%. Ngakhale kuti ukusungabe kupanga, ukuwonjezera kwambiri magwiridwe antchito azachuma komanso kukhazikika kwa chilengedwe pantchito zamigodi. Njira yokonzanso iyi ya "kukonzanso-kusintha-mopitirira muyeso, kukweza magwiridwe antchito" ikukhala chida chofunikira kwambiri chaukadaulo cholimbikitsira kugwiritsa ntchito bwino zida zamigodi komanso kugwiritsa ntchito bwino.
