Kev siv tshuab laser cladding: kev kho laser cladding ntawm cov tshuab tsuas thee sprocket
Hauv kev ua haujlwm khawb thee, lub log saw ntawm lub tshuab khawb thee, ua ib feem tseem ceeb ntawm lub kaw lus traction, raug kev thauj khoom hnyav, kev sib txhuam siab, thiab kev cuam tshuam loj heev rau lub sijhawm ntev. Cov txheej txheem kho ib txwm muaj feem ntau ua tsis tau tiav cov txiaj ntsig kho kom zoo.
Cov Teeb Meem Hauv Kev Lag Luam
Cov txheej txheem kho ib txwm muaj xws li kev vuam thiab kev txau tshuaj thermal muaj teeb meem nrog kev kho tsis raug, lub zog sib txuas tsis zoo, thiab thaj chaw kub loj. Thaum lub log saw ntawm lub tshuab khawb thee ua haujlwm nyob rau hauv qhov xwm txheej hnyav, cov txheej txheem kho no feem ntau tsis ua tiav cov kev xav tau ntawm kev khawb thee zoo thiab muaj kev nyab xeeb hauv cov chaw khawb thee niaj hnub no.
Qhov no cuam tshuam ncaj qha rau kev ua haujlwm ruaj khov thiab kev saib xyuas lub voj voog ntawm cov khoom siv. Thaum lub sprocket raug hnav hnyav lossis puas tsuaj, lub neej kev pabcuam ntawm cov txheej txheem kho ib txwm muaj feem ntau luv luv, thiab kev hloov pauv ntau zaus coj cov nqi kho khoom siv siab thiab kev poob sijhawm.
Lub voj voog yuav khoom ntev thiab tus nqi siab ntawm cov khoom tshiab, thaum muab ua ke, ua rau muaj kev txwv loj rau kev ua haujlwm zoo thiab cov txiaj ntsig kev lag luam ntawm cov lag luam thee.
Kev zoo dua ntawm kev siv tshuab
Cov thev naus laus zis laser cladding yog raws li cov yam ntxwv ntawm lub zog ceev ntawm cov teeb laser, uas yaj sai sai cov hmoov hlau nrog cov khoom tshwj xeeb rau ntawm qhov chaw ntawm lub substrate, thiab khov kho hauv lub sijhawm luv luv los tsim cov txheej cladding ua haujlwm siab uas tau sib txuas nrog cov hlau rau lub substrate.
Piv rau cov txheej txheem kho qhov chaw ib txwm muaj, laser cladding muaj cov txiaj ntsig tshwj xeeb. Lub sijhawm luv luv thiab lub zog ntawm laser ua rau muaj kev cuam tshuam tsawg kawg nkaus rau ntawm lub substrate thiab qis deformation thaum lub sijhawm yaj.
Cov thev naus laus zis no tuaj yeem tswj tau qhov tuab, cov duab, thiab kev ua tau zoo ntawm cov txheej cladding, yog li ua tiav kev kho kom raug ntawm cov khoom hnav thiab puas tsuaj. Cov yam ntxwv ntawm kev sib txuas ntawm cov hlau ua kom muaj zog sib txuas ntawm cov txheej kho thiab cov khoom siv substrate.
Txheej Txheem Ua Ntej
Cov txheej txheem kho kom zoo nkauj siv laser cladding ua raws li cov txheej txheem nruj heev. Kauj ruam thawj zaug yog theem ua ntej kev kho mob, uas suav nrog kev ntxuav cov khoom ntawm cov khoom kom huv si nrog cov organic solvents kom tshem tawm cov roj av, xeb, thiab cov khoom tsis huv.
Tom qab ntawd, kev kho qhov chaw ntxhib yuav raug ua, feem ntau yog siv cov txheej txheem xws li xuab zeb thiab txhuam kom ua rau qhov chaw ntxhib dua thiab txhim kho kev sib txuas ntawm cov txheej thiab cov khoom siv. Cov kauj ruam ua ntej no yuav zoo li yooj yim, tab sis lawv yog lub hauv paus rau kev ua kom zoo.
Tom ntej no, yuav muaj kev ntsuam xyuas qhov tsis zoo los ntsuam xyuas qhov hnav, tawg, thiab lwm yam mob ntawm cov khoom siv los ntawm kev sim tsis ua puas tsuaj, thiab txiav txim siab thaj chaw kho thiab txoj kev npaj kho. Kauj ruam no pab cov engineers tsim cov tswv yim kho kom zoo tshaj plaws.
Cov txheej txheem tseem ceeb
Kev kho cov khoom siv yog cov txheej txheem tseem ceeb ntawm kev kho laser cladding. Cov kws ua haujlwm yuav tsum tau kho cov kev cai ntawm cov khoom siv laser cladding raws li qhov loj me, cov duab, thiab cov kev xav tau kho ntawm cov khoom, suav nrog lub zog laser, kev ceev scanning, qhov chaw diameter, qhov ceev ntawm kev pub hmoov, thiab lwm yam.
Rau cov txheej cladding tuab dua, nws yog qhov tsim nyog los nce lub zog laser thiab tus nqi pub hmoov, thaum txo qhov ceev scanning kom tsim nyog. Rau cov khoom nyias-phab lossis cov khoom uas muaj qhov xav tau siab, nws yog qhov tsim nyog los txo lub zog laser thiab nce qhov ceev scanning kom txo qhov kub cuam tshuam thiab deformation. Thaum lub sijhawm txheej txheem cladding, yuav tsum tau them sai sai rau kev tswj hwm tus nqi sib tshooj ntawm cov txheej cladding, feem ntau ntawm 30% -50%, kom ntseeg tau tias qhov txuas ntxiv thiab sib xws ntawm cov txheej cladding.
Kev tswj xyuas zoo
Kev saib xyuas cov txheej txheem yog ib kauj ruam tseem ceeb hauv kev ua kom zoo ntawm cov cladding. Kev saib xyuas lub sijhawm tiag tiag ntawm cov txheej txheem yaj siv cov ntsuas kub infrared, CCD koob yees duab, thiab lwm yam khoom siv, saib xyuas cov yam ntxwv xws li qhov kub ntawm lub pas dej yaj thiab cov morphology ntawm cov txheej yaj.
Thaum qhov kub ntawm lub pas dej ua kom yaj siab dhau, nws yuav ua rau muaj qhov tsis zoo xws li cov qauv ntxhib thiab cov qhov hws hauv txheej cladding. Lub sijhawm no, nws yog qhov tsim nyog los txo lub zog laser lossis nce qhov ceev scanning raws sijhawm. Yog tias qhov chaw ntawm txheej cladding tsis sib npaug, nws yog qhov tsim nyog los kho qhov nrawm ntawm kev pub hmoov thiab txoj kev scanning.
Lub peev xwm tswj tau qhov tseeb tiag tiag no ua rau cov thev naus laus zis laser cladding ua kom ntseeg tau tias qhov kho kom zoo thiab ruaj khov, ua tau raws li qhov yuav tsum tau ua ntawm kev tsim khoom lag luam rau kev kho kom zoo.
Cov txheej txheem ua tiav tom qab
Tom qab kho cov khoom siv laser cladding tiav lawm, yuav tsum muaj ntau yam txheej txheem tom qab ua tiav. Ua ntej, txhawm rau tshem tawm cov kev ntxhov siab seem hauv cov txheej cladding thiab txhim kho cov qauv me me thiab cov khoom, cov khoom kho feem ntau yuav raug kho cua sov.
Cov txheej txheem kho cua sov uas siv ntau suav nrog kev annealing, tempering, thiab lwm yam. Kev kho annealing tuaj yeem txo qhov nyuaj ntawm txheej cladding, txhim kho plasticity thiab toughness; Kev kho tempering tuaj yeem tshem tawm cov kev ntxhov siab seem, ruaj khov cov qauv, thiab txhim kho kev ua tau zoo ntawm txheej cladding.
Raws li qhov yuav tsum tau ua kom raug ntawm lub sprocket, cov khoom kho tau raug ua tiav los ntawm kev siv tshuab, xws li tig, sib tsoo, thiab lwm yam, kom ntseeg tau tias qhov ntev thiab qhov roughness ntawm cov khoom ua tau raws li qhov yuav tsum tau tsim. Cov kauj ruam no ua kom ntseeg tau tias cov khoom kho tau tuaj yeem haum thiab rov qab ua haujlwm li qub.
