Pwmua lub luag haujlwm tseem ceeb heev hauv kev lag luam niaj hnub no, thiab nws qhov zoo ncaj qha txiav txim siab qhov zoo ntawm cov khoom. Txhim kho lub neej kev pabcuam thiab qhov tseeb ntawmpwmthiab ua kom lub voj voog tsim khoom luv dua yog cov teeb meem kev siv tshuab uas ntau lub tuam txhab xav tau daws sai sai. Txawm li cas los xij, cov hom kev ua tsis tiav xws li kev tawg, kev hloov pauv, kev hnav, thiab txawm tias kev tawg feem ntau tshwm sim thaum siv covpwm.Yog li hnub no, tus editor yuav qhia rau koj txog plaub txoj hauv kev kho pwm, cia peb saib.
Kev kho vuam argon arc
Kev vuam yog ua los ntawm kev siv lub arc hlawv ntawm cov hlau vuam uas pub tas mus li thiab cov khoom ua haujlwm ua qhov chaw kub, thiab cov pa roj tiv thaiv arc txau los ntawm lub qhov vuam lub qhov. Tam sim no, argon arc vuam yog ib txoj kev siv ntau, uas tuaj yeem siv rau feem ntau cov hlau loj, suav nrog cov hlau carbon thiab cov hlau alloy. MIG vuam yog qhov tsim nyog rau cov hlau tsis xeb, txhuas, magnesium, tooj liab, titanium, zirconium thiab nickel alloys. Vim nws tus nqi qis, nws yog dav siv rau kev kho pwm vuam. Txawm li cas los xij, nws muaj qhov tsis zoo xws li thaj chaw vuam loj cuam tshuam los ntawm cua sov thiab cov pob qij txha loj. Kev kho pwm precision tau hloov maj mam los ntawm laser vuam.
Kho tshuab kho pwm
PwmTshuab kho pwm yog cov khoom siv thev naus laus zis siab los kho qhov hnav ntawm qhov pwm thiab kev ua haujlwm tsis zoo. Lub tshuab kho pwm ua kom lub pwm muaj zog kom muaj lub neej ntev thiab muaj txiaj ntsig zoo rau kev lag luam. Ntau yam hlau sib xyaw (carbon steel, alloy steel, cast iron), nickel-based alloys thiab lwm yam khoom siv hlau tuaj yeem siv los txhawb thiab kho qhov chaw ntawm pwm thiab cov khoom ua haujlwm, thiab ua rau lub neej ua haujlwm ntev dua.
1. Lub hauv paus ntsiab lus ntawm lub tshuab kho pwm
Nws siv lub hauv paus ntsiab lus ntawm kev tso tawm hluav taws xob ntau zaus los kho qhov tsis zoo ntawm qhov chaw thiab kev hnav ntawm cov hlaupwmlos ntawm kev vuam qhov chaw tsis muaj cua sov rau ntawm qhov chaw ua haujlwm. Qhov tseem ceeb tshaj plaws yog tias thaj chaw cuam tshuam los ntawm cua sov yog me me, cov pwm yuav tsis raug deformed tom qab kho, tsis muaj annealing, tsis muaj kev ntxhov siab concentration, thiab tsis muaj Cracks tshwm sim los xyuas kom meej qhov kev ncaj ncees ntawm cov pwm; nws kuj tseem siv tau los txhawb qhov chaw ntawm cov pwm workpiece kom ua tau raws li qhov yuav tsum tau ua ntawm cov pwm txoj kev hnav tsis kam, tiv taus cua sov, thiab tiv taus corrosion.
2. Scope ntawm daim ntawv thov
Tshuab kho tuag siv tau rau hauv tshuab, tsheb, kev lag luam teeb pom kev zoo, khoom siv hauv tsev, roj av, tshuaj lom neeg thiab hluav taws xob, rau kev kub hnyiabpwm, cov cuab yeej ua kom sov extrusion zaj duab xis, pwm kub forging, yob thiab cov khoom tseem ceeb kho thiab kho kom muaj zog ntawm qhov chaw.
Piv txwv li, lub tshuab kho hluav taws xob ESD-05 hom siv tau los kho cov pwm txhaj tshuaj ntawm kev hnav, kev raug mob thiab khawb, thiab kho cov xeb, poob thiab kev puas tsuaj ntawm cov pwm tuag-casting xws li zinc-aluminium die-casting pwm. Lub zog ntawm lub tshuab yog 900W, qhov hluav taws xob nkag yog AC220V, zaus yog 50 ~ 500Hz, qhov hluav taws xob ntau yog 20 ~ 100V, thiab feem pua ​​​​​​ntawm cov zis yog 10% ~ 100%.
Kev kho txhuam plating
Cov txheej txheem txhuam plating siv lub cuab yeej tshwj xeeb DC fais fab mov. Lub ncej zoo ntawm lub zog fais fab txuas nrog lub cwj mem plating ua lub anode thaum txhuam plating; lub ncej tsis zoo ntawm lub zog fais fab txuas nrog lub workpiece ua lub cathode thaum txhuam plating. Lub cwj mem plating feem ntau siv cov graphite blocks zoo purity siab ua cov khoom siv anode, lub graphite block yog qhwv nrog paj rwb thiab lub tes tsho polyester paj rwb uas tsis yooj yim hnav.
Thaum ua haujlwm, lub rooj sib dhos fais fab raug kho kom haum rau qhov hluav taws xob tsim nyog, thiab tus cwj mem plating uas muaj cov tshuaj plating raug txav mus rau qhov ceev ntawm qhov sib cuag ntawm qhov chaw ntawm qhov chaw kho. Cov hlau ions hauv cov tshuaj plating kis mus rau qhov chaw ua haujlwm raws li qhov kev ua ntawm lub zog hluav taws xob. Ntawm qhov chaw, cov electrons tau txais ntawm qhov chaw raug txo kom ua cov hlau atoms, yog li cov hlau atoms no tau tso thiab crystallized los ua ib txheej, uas yog, kom tau txais cov txheej txheem sib xws uas xav tau ntawm qhov chaw ua haujlwm ntawm lub pwm yas qhov chaw uas yuav tsum tau kho.
Tshuab ntxuav qhov chaw plasma, tshuab vuam plasma tsuag, kho qhov chaw ncej
Kev kho qhov chaw laser
Kev vuam laser yog kev vuam uas siv lub teeb laser ua qhov chaw kub los ntawm kev tsom mus rau cov kwj deg photon monochromatic uas muaj zog heev. Txoj kev vuam no feem ntau suav nrog kev vuam laser tas mus li thiab kev vuam laser pulsed power. Qhov zoo ntawm kev vuam laser yog tias nws tsis tas yuav tsum tau ua hauv lub tshuab nqus tsev, tab sis qhov tsis zoo yog tias lub zog nkag mus tsis muaj zog npaum li kev vuam electron beam. Kev tswj lub zog raug tuaj yeem ua tiav thaum vuam laser, yog li kev vuam ntawm cov khoom siv precision tuaj yeem ua tiav. Nws tuaj yeem siv rau ntau yam hlau, tshwj xeeb tshaj yog los daws qhov kev vuam ntawm qee cov hlau nyuaj rau vuam thiab cov hlau sib txawv. Nws tau siv dav raupwmkho.
Kev siv tshuab laser cladding
Cov txheej txheem laser cladding nto yog kom sai sai cua sov thiab yaj cov hmoov hlau lossis cov hmoov av ceramic thiab qhov chaw ntawm lub substrate nyob rau hauv qhov kev ua ntawm lub teeb laser. Tom qab lub teeb raug tshem tawm, qhov txias txias tus kheej tsim cov txheej txheej saum npoo nrog qhov nrawm qis heev thiab kev sib xyaw ua ke nrog cov khoom siv substrate. , Yog li kom txhim kho qhov chaw ntawm lub substrate abrasion tsis kam, corrosion tsis kam, kub tsis kam, oxidation tsis kam thiab hluav taws xob yam ntxwv ntawm txoj kev txhim kho nto.
Piv txwv li, tom qab carbon-tungsten laser cladding ntawm 60 # hlau, qhov nyuaj yog txog li 2200HV lossis ntau dua, thiab qhov hnav tsis kam yog li 20 npaug ntawm lub hauv paus 60 # hlau. Tom qab laser cladding CoCrSiB alloy ntawm qhov chaw ntawm Q235 hlau, qhov hnav tsis kam thiab qhov corrosion tsis kam ntawm nplaim taws txau tau piv, thiab nws tau pom tias qhov corrosion tsis kam ntawm tus qub yog siab dua li ntawm qhov kawg.
Laser cladding muaj peev xwm muab faib ua ob pawg raws li cov txheej txheem pub hmoov sib txawv: txoj kev npaj ua ntej hmoov thiab txoj kev pub hmoov sib dhos. Cov teebmeem ntawm ob txoj kev zoo sib xws. Txoj kev pub hmoov sib dhos muaj kev tswj hwm yooj yim, tus nqi nqus hluav taws xob laser siab, tsis muaj qhov hws sab hauv, tshwj xeeb tshaj yog cladding cermet, uas tuaj yeem txhim kho qhov kev ua tau zoo tiv thaiv kev tawg ntawm cov txheej cladding, yog li cov theem ceramic nyuaj tuaj yeem ua tau zoo. Qhov zoo ntawm kev faib tawm sib xws hauv cov txheej cladding.
