Kev siv cov lasers los ntawm kev sib cuam tshuam nrog cov teeb meem, kev ua lossis moulding raws li qee qhov yuav tsum tau ua, kev suav sau xa mus rau kev tsim lub teeb. Hauv 20 xyoo dhau los, kev siv tshuab teeb pom kev tau nkag mus rau cov chaw lag luam siab thiab kev lag luam, thiab tau pib hloov lossis hloov qee yam kev lag luam tsim muaj. Hauv kev tsim kho tsheb nyob hauv cov teb chaws vam meej, 50% -70% feem ntawm cov khoom yog laser ua. Lub teeb ua tshuab thev naus laus zis ua si lub luag haujlwm tseem ceeb hauv kev txhim kho R&D thiab kev tsim qib ntawm kev lag luam tsheb.
Ua ntej, cov yam ntxwv ntawm kev siv tshuab teeb pom kev zoo
Tam sim no, qhov khoom siv hluav taws xob hauv kev siv tshuab teeb pom kev zoo yog cov xim laser ntau. Lub nqaj laser muaj cov yam ntxwv ntawm kev siv lub zog loj, siab palladium thiab siab ncaj qha, uas ua rau lub teeb tsim thev naus laus zis muaj ntau yam zoo uas tsis muaj nyob rau hauv hom kev tsim khoom tsoos. Lub cuab tam siv hauv cov thev naus laus zis no yog "rab riam laser", tsis muaj cov cuab yeej hnav thaum ua haujlwm; tsis muaj quab yuam cuam tshuam rau qhov chaw ua haujlwm thaum lub sijhawm machining, yog li ntawd qhov chaw ua haujlwm tsis muaj qhov txias ua haujlwm deformation; vim tias lub zog kev txhaj tshuaj nrawm yog siab thaum lub sijhawm machining, qhov cuam tshuam tshav kub rau lub workpiece yog tsawg heev, yog li ntawd qhov chaw ua haujlwm no tsis tshua muaj kev cuam tshuam thermal thiab tuaj yeem mus txog lossis mus txog "txias" machining xeev, ua rau kev ua haujlwm siab ua haujlwm uas tsis tuaj yeem ua los ntawm cov tswv yim ib txwm muaj; lub laser muaj qhov sib kis tau zoo (kev taw qhia hloov ntawm lub nqaj, kev sib hloov, ntsuas lub zog, thiab lwm yam) thiab lub sijhawm tswj (qhib), tawm, lub sijhawm ntawm cov mem tes), tshwj xeeb tshaj yog tsim nyog rau kev siv tshuab, kev ua haujlwm siab hauv kev tsim khoom loj; laser ua cov khoom tawm, cov duab, qhov loj thiab cov khoom siv ib puag ncig muaj qhov kev ywj pheej loj; suab nrov tsawg, tsis muaj teeb meem tawg thiab rov qab los dua, cov txheej txheem ntau lawm muaj kuab paug ib puag ncig tsawg; nws tuaj yeem txuag mould, luv lub voj voog kev tsim khoom, txo tus nqi txhim kho; cov khoom siv pov tseg tsawg dua, thiab kev tsim khoom qis hauv cov khoom lag luam loj.
Thib ob, qeb ntawm lub teeb kev tsim tshuab hauv kev lag luam tsheb
Lub teeb ci thev naus laus zis hauv kev lag luam tsheb tuaj yeem muab faib ua peb pawg: lub teeb "txias" kev ua, lub teeb "kub" kev ua, thiab lub teeb ua kom sai.
1. Lub teeb "txias" kev siv tshuab ua haujlwm
Kev tsim hluav taws xob sib txuas rau cov txheej txheem ua haujlwm txias xws li laser txiav, laser drilling, laser npav, thiab laser txiav.
Lub laser txiav ceev yog nrawm, qhov phais txiav yog du thiab tiaj tus, lub parallelism ntawm lub tshuab nqaj yog qhov zoo, tsis muaj kev ua haujlwm tom qab yog yuav; lub hlais yog nqaim; lub qhov hlais tsis muaj kev nyuaj siab kho tshuab thiab tsis muaj shear burr; cov txheej txheem ua tiav yog siab, qhov rov ua tau zoo, thiab lub ntsej muag ua haujlwm tsis puas.
Laser drilling ceev thiab cov peev txheej siab, tsim rau ntau yam ntawm cov pab pawg neeg high-density pab pawg ua qhov; laser drilling tuaj yeem tau txais qhov sib sib zog nqus mus rau qhov loj me, tuaj yeem ua tiav ntawm tawv, nkig, muag muag thiab lwm yam khoom siv, txawm tias nyob hauv cov qhov me me yog kho rau ntawm qhov chaw inclined ntawm cov khoom siv tshuab nyuaj; cov txheej txheem laser drilling yog huv si thiab tsis muaj kuab paug.
Laser npav tsis txuas tsis cuag, cim nrawm, cim tsis yooj yim rau hnav, laser npav lub tshuab yog yooj yim los ua ke nrog tus kav raj xa dej.
Laser txiav yog txheej txheem zoo ib yam li milling hauv kev siv lub tshuab ua haujlwm. Nws siv kev tsom xam cov laser ntaj los txiav cov khoom txheej los ntawm txheej.
2. Lub teeb "kub" txheej txheem thev naus laus zis
Lub teeb kev tsim hluav taws xob ua tau yooj yim rau cov txheej txheem ua pa hluav taws xob suav nrog laser vuam, laser nto lub zog, laser cladding, thiab alloying.
Laser welding yog txheej txheem nyob rau hauv uas lub siab siv laser nqaj siv nyob rau hauv zos kom sov cov hlau yuav tsum yaj saum tus melting kub los ua qhov sib txuas welded. Nws tuaj yeem txuas cov ntaub ntawv tshwj xeeb xws li siab melting point hlau, tsis yog hlau, cov ntaub ntawv sib xyaw, thiab lwm yam. Nws tseem tuaj yeem paub cov vuam ntawm cov khoom tsis sib xws thiab vuam ntawm cov qauv tshwj xeeb; Lub weld muaj cov haujlwm ntawm "tu tus kheej", lub weld zoo yog siab; lub vuam tuaj yeem nqa tawm kom raug, feem ntau tsis tas yuav tsum sau Cov hlau; lub nqaj laser thiab cov cuab yeej siv ntau yam los ua cov txheej txheem hloov kho tau yooj yim los ntawm kev coj ua lub teeb, vuam qib yog qhov siab thiab kev ua haujlwm ntau; nyob rau hauv lub siab zog nqaj hlau vuam, qhov loj tshaj ntawm cov yam ntxwv ntawm lub vuam laser yog tias tsis muaj lub tshuab nqus tsev, thiab tsis muaj duab xoo hluav taws xob tsim. Cov.
Laser nto kho tau muab faib ua laser theem kev sib hloov ua haujlwm tawv thiab laser fusion hardening. Laser theem hloov kho qhov nyuaj, tseem hu ua laser quenching, yog kom nrawm nrawm dua qhov chaw ua haujlwm nrog lub siab lub zog laser nqaj, kom lub npoo kub ntawm cov hlau tsis muaj hlau lossis cov hlau nyhav nce mus rau qhov chaw siab dua cov theem taw tes nrog nrawm nrawm heev. Thaum lub laser nqaj tawm ntawm qhov tsis zoo, Vim tias cov cua sov ua kom sov, lub hauv qab hauv lub xeev txias tau nrawm txias thiab nws tus kheej txias thiab quenched kom tau txais cov txheej txheej ua kom tawv tawv, thiab qhov nyuaj feem ntau siab dua li cov pa quenching hardness; lub laser fusion hardening txheej txheem zoo ib yam li cov txheej txheem dhau los, tshwj tsis yog tias lub laser ua rau cov nplaim ntawm cov khoom yog qhov kub mus rau qhov kub dua, thiab cov nplaim hluavtaws-txheej tawv ntawm cov qauv zoo yog tsim nyob rau saum npoo ntawm qhov kawg.
Laser cladding siv lub siab ua hluav taws xob laser teeb pom kev zoo rau cov khoom tso tawm kom sai fuse nws nrog txheej nyias nyob rau saum npoo ntawm txheej los ua ib txheej alloy nrog cov sib txawv kiag li sib txawv thiab cov khoom sib xyaw metallurgically sib raug rau daim nyias nyias.
3. Kev tiv thaiv sai
Lub hauv paus ntsiab lus ntawm optical sai prototyping tshuab yog tswj cov qauv thiab ntaub ntawv raws li cad ntawm ib feem nyob rau hauv kev tswj ntawm lub khoos phis tawm. Lub nqaj laser yog siv los ua kom cov tshuaj molding txheej los ntawm txheej. Qhov saum npoo (txheej) ntawm ib feem yog tsim los ntawm cov ntsiab lus thiab cov kab, thiab saum npoo yog ncaj ncaj rau hauv peb qhov ntev. Cov txheej txheem ntawm cov qauv khov lossis qee qhov. Kev siv cov cuab yeej kho qhov muag pom sai sai tuaj yeem txo qhov kev loj hlob ntawm cov khoom lag luam, txo cov nqi txhim kho, thiab tuaj yeem tsim cov khoom lag luam uas hloov mus rau kev hloov hauv kev ua lag luam, thiab tswj thiab txhim kho kev sib tw ntawm cov khoom hauv kev ua lag luam. Nyob rau tib lub sijhawm, kev siv tshuab kho qhov muag kom ceev nrawm kuj yog qhov ntsuas kev ua tau zoo kom ua tiav cov khoom siv hluav taws xob zoo thiab kev tsim khoom sai.
Hauv lub xyoo pua tshiab, kev lag luam tsheb pib mus rau theem cov roj ntshiv uas tuaj yeem ua qhov kev hloov pauv hloov raws li cov neeg siv xav tau. Kev lag luam tsheb tau tsim txoj hauv kev hloov pauv ntau lawm. Qhov kev lag luam tsheb niaj hnub no tseem tab tom tsim hauv kev coj ntawm kev lag luam thev naus laus zis, thiab kev siv tsheb thev naus laus zis tau ntsib qhov kev hloov pauv ntawm kev siv tshuab ua ib txwm muaj rau kev tsim thev naus laus zis. Lub tshuab tsim hluav taws xob tau txhaj cov khoom loj hlob rau kev txhim kho thiab tsim cov tsheb. Nws tuaj yeem cia siab tias daim ntawv thov ntawm lub teeb tsim tshuab hauv kev lag luam tsheb yuav nthuav dav nyob rau xyoo no thiab yuav dhau los ua cov txheej txheem tseem ceeb rau kev lag luam tsheb.
