Cov txheej txheem tseem ceeb ntawm Laser Cladding Technology hauv Kev Kho Agricultural Machinery

Txoj kev no tsuas yog siv tau rau cov khoom siv ua liaj ua teb uas raug kev txom nyem los ntawm kev sib txhuam ntev ntev, xws li lub tsheb laij teb fais fab coj-tawm shafts, lub nruas nruas shafts, plowshare cutting edges, thiab seeder furrow openers. Cov txheej txheem kho kom meej meej thiab tswj tau: ua ntej, ua ntej txheej txheej ntawm cov khoom hnav kom tshem tawm cov roj stains, xeb, thiab qaug zog txheej, kom ntseeg tau tias qhov chaw kho kom huv si thiab tiaj tus; tom qab ntawd xaiv cov ntaub ntawv cladding sib txuam (feem ntau siv hnav- cov ntaub ntawv tiv taus xws li WC-Co cemented carbide thiab NiCrBSi npib tsib xee-raws li alloy) raws li cov khoom siv (xws li 45 # steel, alloy steel) thiab ua haujlwm; precisely tso cov ntaub ntawv rau ntawm hnav cov khoom sivLaser Claddingcov khoom siv, tswj tsis tau xws li laser fais fab thiab hmoov pub ceev kom tsim tau ib lub zog metallurgical daim ntawv cog lus ntawm cov txheej cladding thiab substrate, ua tiav cov seem rov qab; Thaum kawg, ua tiav machining ntawm lub clad tivthaiv kom nws qhov tseeb qhov tseeb raws li qhov yuav tsum tau ua. Piv txwv li, rau lub tsheb laij teb ncej qhov chaw nrog ib tug hnav npaum li cas ntawm 0.5-5 hli, qhov ntev ntev ntawm lub taub hau taub hau yuav tswj tau nyob rau hauv ± 0.02 hli tom qab kho siv txoj kev no, tag nrho raws li cov kev xav tau kev sib dhos tom ntej.

Rau kev tawg tsis xws luag hauv cov tshuab ua liaj ua teb xws li casings, gears, thiab hydraulic tivthaiv vaj tse uas tshwm sim los ntawm hnyav loads thiab vibrations, laser cladding tawg txoj kev kho kom zoo. Qhov sib txawv ntawm kev kho cov vuam tsoos uas ua rau thermal deformation thiab tawg tawg, txoj kev no muaj qhov zoo ntawm cov cua kub qis thiab nqaim cua sov- thaj tsam cuam tshuam. Cov kauj ruam tshwj xeeb yog: ua ntej, ua qhov tsis txaus ntseeg ntawm cov kab nrib pleb los txiav txim siab qhov ntev, qhov tob, thiab kev taw qhia ntawm cov kab nrib pleb; qhib meej V-zoo li tus lossis U-zoo li tus grooves raws cov kev taw qhia tawg kom yooj yim rau kev ntim cov ntaub ntawv cladding; xaiv cov ntaub ntawv cladding txuam nrog cov khoom siv substrate (piv txwv li, qis-carbon alloy cladding hmoov rau cov khoom siv hlau); precisely scan raws cov grooves nrog laser beams fuse cov ntaub ntawv cladding nrog lub substrate thiab sau cov kab nrib pleb; ua qhov tsis txaus ntseeg thib ob tom qab kho kom ntseeg tau tias cov kab nrib pleb tau kho tau zoo yam tsis muaj qhov tsis xws luag. Piv txwv li, tom qab kho cov kab nrib pleb nyob rau hauv lub gearbox vaj tse ntawm ib tug sib tov harvester sivLaser Claddingthev naus laus zis, cov khoom siv kho tshuab ntawm cov vaj tsev tuaj yeem rov qab los rau ntau dua 90% ntawm cov khoom tshiab, kom tsis txhob muaj teeb meem tsis ua hauj lwm los ntawm cov vaj tsev deformation tom qab kev kho vuam tsoos.

Txoj kev no siv tau rau cov khoom siv ua liaj ua teb uas tseem tsis tau ua tiav tag nrho tab sis tau pom cov tsos mob thaum ntxov ntawm kev hnav thiab corrosion, xws li seeder fertilizer tubes, irrigation equipment joints uas nyob rau hauv ntev -lub sij hawm sib cuag nrog cov av thiab tshuaj chiv, thiab iav hniav nto raug rau siab - zaus vibrations. Lub hom phiaj tseem ceeb yog los npaj cov txheej txheem siab - kev ua tau zoo ntawm cov khoom siv los ntawm Laser Claddingtxhawm rau ua ntej - ntxiv dag zog rau cov khoom siv ua haujlwm thiab txuas ntxiv nws lub neej kev pabcuam. Cov txheej txheem kho tsis tas yuav tos kom cov khoom ua tsis tiav thiab tuaj yeem ua tiav thaum lub sijhawm tu: tom qab kev kho kom yooj yim ntawm cov khoom siv saum npoo, xaiv corrosion-resistant thiab hnav- cov ntaub ntawv tiv thaiv cladding, thiab npaj 0.3-2 hli tuab txheej ntawm cov khoom siv los ntawm laser cladding; tsis tas yuav tsum tau ua tiav kev ua tiav tom ntej, thiab nws tuaj yeem ua tau raws li cov kev xav tau ntawm kev pabcuam. Piv txwv li, tom qab NiCrBSi npib tsib xee-raws li alloy cladding ntxiv dag zog rau lub puab phab ntsa ntawm lub seeder chiv tube, nws corrosion kuj yog txhim kho los ntawm 3-5 zaug, uas muaj peev xwm tiv taus qhov yaig ntawm cov tshuaj chiv tshaj tawm thiab ncua kev pab cuam lub neej ntawm cov khoom los ntawm ntau tshaj 2 zaug.

Raws li keeb kwm yav dhau los ntawm qhov loj - nplai thiab kev txhim kho ntawm kev ua liaj ua teb niaj hnub no,Laser Claddingthev naus laus zis tsis tuaj yeem txo qis kev ua haujlwm thiab kev saib xyuas cov nqi ntawm cov tshuab ua liaj ua teb rau cov neeg ua liaj ua teb thiab ua liaj ua teb, txhim kho kev ua liaj ua teb ntau lawm, tab sis kuj txhawb kev hloov pauv ntawm kev ua liaj ua teb machinery txij nkawm kev lag luam mus rau qhov zoo thiab kev cog qoob loo.
