Cov txheej txheem ob-kauj ruam (txheej txheem txheej txheem) ntawm txheej txheem laser cladding
Nyob rau hauv txoj kev no, ua ntej sivlaser cladding khoom, cov khoom siv cladding yog muab tso rau ntawm qhov chaw ua hauj lwm thiab tom qab ntawd melted thiab solidified los ntawm laser los tsim ib txheej cladding.
Muaj ob txoj hauv kev los npaj cov khoom siv cladding:
- Pre-txheej: feem ntau ua manually thiab yog qhov kev lag luam thiab yooj yim tshaj plaws. Tom qab lub workpiece nto qhuav, laser cladding yog nqa tawm. Txawm li cas los xij, txoj kev no muaj kev ua haujlwm tsawg, tsis sib xws cladding txheej thickness, thiab tsis haum rau ntau lawm.
- Daim ntawv muab tso ua ntej: ib qho me me ntawm cov ntaub ntawv ntxiv rau cov khoom siv cladding, molded rau hauv ib daim ntawv zoo, muab tso rau ntawm ib feem ntawm lub workpiece uas yuav tsum tau clad, thiab ces ua tiav los ntawm laser. Txoj kev no muaj cov hmoov siv siab, ruaj khov zoo, thiab tsim nyog rau qee qhov sib sib zog nqus qhov chaw, xws li lub taub me me valve lub cev. Txoj kev no tuaj yeem tau txais cov txheej txheem zoo.
Ib-kauj ruam txoj kev (synchronous method) ntawm laser cladding txheej txheem.
Qhov no yog cov txheej txheem ntawm ib txhij irradiating lub workpiece nrog ib tug laser beam thiab xa cov khoom cladding mus rau lub laser active cheeb tsam. Muaj ob txoj hauv kev:
- Synchronous hmoov pub txoj kev: ib qho tshwj xeeb dav hlau hmoov pub khoom siv los pub ib leeg lossis cov hmoov sib xyaw rau hauv lub pas dej molten. Lub cladding txheej thickness yog kho los ntawm kev tswj cov hmoov noj cov nyiaj thiab laser scanning ceev. Loose hmoov muaj qhov nqus tau siab rau laser thiab thermal efficiency, uas tuaj yeem tau txais txheej txheej tuab dua li lwm txoj hauv kev thiab yooj yim rau kev ua tiav automation.
- Synchronous wire feeding method: Cov txheej txheem txheej txheem ntawm txoj kev no yog tib yam li cov txheej txheem synchronous hmoov pub mis, tab sis cov khoom siv encapsulated yog ua ntej ua rau hauv cov hlau los yog txhaws hlau. Txoj kev no yooj yim, tsis txhob nkim cov ntaub ntawv, thiab yooj yim dua los xyuas kom meej lub uniformity ntawm cladding txheej muaj pes tsawg leeg, tshwj xeeb tshaj yog thaum lub cladding txheej yog ib tug composite khoom, qhov zoo ntawm cov cladding txheej yuav tsis cuam tshuam los ntawm sib txawv compositions, hmoov tshwj xeeb nqus. , los yog particle loj. Los ntawm kev ua kom zoo ntawm cov hlau los ntawm preheating, tus nqi cladding tuaj yeem txhim kho. Txawm li cas los xij, cov hlau saum npoo yog du, uas muaj kev cuam tshuam zoo rau lub laser thiab muaj qis dua kev siv laser. Tsis tas li ntawd, cov txheej txheem tsim cov hlau yog complex, thiab ntau yam thiab specifications yog txwv.
Laser cladding synchronous hmoov pub khoom ntse tshuab
Raws li ib qho ntawm cov khoom tseem ceeb ntawm cov khoom siv cladding, kev ua haujlwm ntawm cov khoom siv hmoov pub ncaj qha cuam tshuam rau qhov zoo ntawm cov txheej txheej cladding. Nrog rau txoj kev loj hlob sai ntawm laser cladding technology thiab qhov yuav tsum tau ua kom raug thiab zoo ntawm txheej cladding, kev txhim kho cov khoom noj khoom haus hmoov zoo yog qhov tseem ceeb tshwj xeeb rau kev ua laser cladding.
Yog li ntawd, Xi'an Guosheng Laser Technology, vam khom rau nws cov thev naus laus zis thiab R & D lub zog, tau tsim cov khoom siv ntse hmoov noj cov khoom siv rau ultra-high-speed laser cladding thiab high-precision synchronous hmoov pub. Cov khoom siv ntse hmoov pub mis tuaj yeem tswj xyuas kev ruaj ntseg hauv lub zog siab thiab cov hmoov loj pub noj cov txiaj ntsig thaum tseem ua si nws qhov tshwj xeeb high-precision micro-hmoov pub noj muaj nuj nqi hauv cov txheej txheem hmoov pub mis.
Ib qho chaw nres tsheb cladding-quenching tshuab cuab yeej siv tag nrho HT-cam khwb cia txaj lub cev nrog cov qauv ruaj khov thiab kev poob siab siab. PLC tswj qhov system muaj "phooj ywg" tib neeg-tshuab sib tham interface, thiab plaub-axis mechanism (X, Y, Z, thiab kev sib hloov axis) tuaj yeem ua tiav kev sib txuas. Nrog rau ib qho chaw nres tsheb tsim, qauv yooj yim, thiab kev ua haujlwm yooj yim, tag nrho cov dej txias cladding / quenching lub taub hau tuaj yeem ua tiav 24- teev ua haujlwm tas mus li. Qhov siab tshaj plaws tig txoj kab uas hla ntawm cov cuab yeej yog Ø600mm, thiab qhov siab tshaj plaws clamping ntev ntawm lub workpiece yog 3000mm, nrog lub siab tshaj plaws load peev xwm ntawm 3T. Nws tuaj yeem paub qhov cladding / quenching ntawm cov voj voog sab nrauv ntawm cov ncej thiab cov discs, nrog rau cov qhov hauv.
Tam sim no, laser cladding tshuab tau txhim kho sai, ua kom paub tab, thiab nkag mus rau theem ntawm kev nce qib thiab kev thov. Laser cladding thev naus laus zis yog ib qho tseem ceeb ntawm kev txhawb nqa thev naus laus zis rau ntsuab remanufacturing thev naus laus zis thiab yog lub tshuab thev naus laus zis uas ua tau raws li lub teb chaws txoj kev txhim kho kom ruaj khov. Suav cov kws tshawb fawb yog nyob rau hauv pem hauv ntej ntawm kev tshawb fawb thoob ntiaj teb hauv kev tshawb fawb theoretical yooj yim, ua rau muaj txiaj ntsig zoo rau kev tsim cov tshuab laser cladding. Txawm li cas los xij, ntawm qhov tod tes, daim ntawv thov qib thiab nplai ntawm laser cladding tshuab tseem tsis tuaj yeem ua tau raws li kev lag luam xav tau. Yog li ntawd, nws yog ib qho tsim nyog los daws cov thev naus laus zis tseem ceeb hauv kev siv engineering, tsim tshwj xeeb alloy hmoov tshuab, tsim cov hmoov pub mis thiab cov thev naus laus zis, tshawb xyuas cov txheej txheem kho tsis muaj kev puas tsuaj, tsim kom muaj kev lees paub zoo thiab kev ntsuam xyuas cov tshuab, thiab siv zog los tsim cov kev siv engineering txhim khu kev qha. . Nyob rau hauv niaj hnub kev lag luam kev lag luam sib tw, laser cladding tshuab muaj peev xwm loj heev.
