Pwm plays lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub no, thiab nws qhov zoo ncaj qha txiav txim siab cov khoom zoo. Txhim kho lub neej kev pab cuam thiab precision ntawm pwm thiab shortening lub voj voog ntawm pwm yog cov teeb meem kev lag luam uas ntau lub tuam txhab yuav tsum tau daws sai. Txawm li cas los xij, cov ntaub ntawv tsis ua haujlwm xws li kev sib tsoo, deformation, hnav, thiab txawm tias tawg feem ntau tshwm sim thaum siv pwm.
Argon arc vuam kho
Vuam yog ua los ntawm kev siv qhov kub hnyiab ntawm qhov txuas txuas txuas txuas txuas txuas thiab cov khoom ua haujlwm raws li qhov chaw tshav kub, thiab cov roj tiv thaiv arc ejected ntawm lub teeb nozzle. Tam sim no, argon arc vuam yog ib txoj kev siv ntau, uas tuaj yeem siv rau feem ntau cov hlau loj, suav nrog carbon steel thiab hlau alloy. Hlau inert gas shielded vuam yog tsim rau stainless hlau, txhuas, magnesium, tooj liab, titanium, zirconium thiab nickel alloys. Vim nws tus nqi qis, nws tau siv dav hauv pwm kho vuam, tab sis nws muaj qhov tsis zoo xws li thaj chaw muaj cua sov loj thiab cov pob qij txha loj. Precision pwm kho tau maj mam hloov los ntawm laser vuam.
Pwm Patching Tshuab Kho
Pwm kho tshuab yog cov cuab yeej siv high-tech los kho pwm nto hnav thiab ua qhov tsis xws luag. Lub tshuab kho pwm txhim kho pwm nrog lub neej ua haujlwm ntev thiab cov txiaj ntsig zoo ntawm kev lag luam. Nws tuaj yeem siv rau ntau yam hlau-raws li alloys (carbon steel, alloy steel, cam khwb cia hlau), npib tsib xee-raws li alloys thiab lwm yam ntaub ntawv hlau los ntxiv dag zog thiab kho qhov chaw ntawm cov pwm thiab cov khoom ua haujlwm, thiab ua kom lub neej ua haujlwm zoo.
1. Lub hauv paus ntsiab lus ntawm pwm kho tshuab
Nws siv lub hauv paus ntsiab lus ntawm high-frequency hluav taws xob hluav taws xob tawm los kho qhov chaw tsis xws luag thiab hnav cov hlau pwm los ntawm athermal surfacing vuam ntawm lub workpiece. Lub ntsiab feature yog hais tias lub tshav kub cuam tshuam cheeb tsam yog me me, thiab cov pwm yuav tsis deformed tom qab kho, tsis muaj annealing, tsis muaj kev ntxhov siab concentration, thiab tsis muaj Cracks tshwm sim los xyuas kom meej qhov zoo ntawm pwm; Nws kuj tseem tuaj yeem siv los ntxiv dag zog rau saum npoo ntawm cov pwm ua haujlwm kom tau raws li qhov hnav tsis kam, kub tsis kam, corrosion kuj thiab lwm yam kev ua haujlwm ntawm pwm.
2. Daim ntawv thov Scope
Lub tshuab kho pwm tuaj yeem siv rau hauv tshuab, tsheb, lub teeb kev lag luam, khoom siv hauv tsev, roj av, tshuaj lom neeg kev lag luam thiab hluav taws xob fais fab kev lag luam, rau kev kho thiab txhim kho saum npoo ntawm cov pwm extrusion kub, cov cuab yeej sov extrusion zaj duab xis, kub forging pwm, yob thiab qhov tseem ceeb.
Piv txwv li, ESD -05 hluav taws xob lub qhov hluav taws xob kho lub tshuab tuaj yeem siv los kho qhov hnav, khaus, thiab khawb ntawm cov pwm txhaj tshuaj, thiab kho xeb, tev, thiab kev puas tsuaj ntawm cov pwm tuag xws li zinc-aluminium tuag. - casting pwm. Lub hwj chim ntawm lub tshuab yog 900W, input voltage yog AC220V, zaus yog 50 ~ 500Hz, qhov voltage ntau yog 20 ~ 100V, thiab cov zis feem pua yog 10 feem pua ~ 100 feem pua.
Txhuam Plating Kho
Lub tshuab txhuam plating siv cov khoom siv hluav taws xob tshwj xeeb DC. Tus ncej zoo ntawm lub hwj huam mov txuas nrog lub plating cwj mem raws li lub anode thaum txhuam plating; tus ncej tsis zoo ntawm lub hwj huam mov yog txuas nrog lub workpiece raws li cathode thaum txhuam plating. Lub plating cwj mem feem ntau yog siv high-purity nplua graphite thaiv raws li cov khoom siv Anode, graphite thaiv qhwv hauv paj rwb thiab hnav-resistant polyester paj rwb tes tsho.
Thaum ua haujlwm, cov khoom siv hluav taws xob sib dhos tau hloov kho kom haum rau qhov tsim nyog, thiab tus cwj mem plating nyob rau hauv cov tshuaj plating yog nyob rau hauv kev sib cuag nrog lub nto ntawm lub workpiece kho ntawm ib tug tej yam txheeb ze ceev, thiab cov hlau ions nyob rau hauv lub plating tov diffuse mus rau lub nto ntawm lub workpiece. workpiece nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb quab yuam Nyob rau saum npoo, electrons tau nyob rau saum npoo yog txo mus rau hlau atoms, thiaj li hais tias cov hlau atoms yog deposited thiab crystallized los ua ib tug txheej, uas yog, yuav tsum tau uniform deposition txheej yog tau ntawm lub ua hauj lwm nto ntawm lub kho yas pwm kab noj hniav.

Laser Surfacing Kho
Laser vuam yog vuam ua los ntawm kev siv lub laser beam tsom los ntawm ib tug high-power coherent monochromatic photon txaus raws li ib tug kub qhov chaw. Txoj kev vuam no feem ntau muaj lub zog tsis tu ncua laser vuam thiab lub zog hluav taws xob laser vuam. Qhov zoo ntawm laser vuam yog tias nws tsis tas yuav tsum tau nqa tawm hauv lub tshuab nqus tsev, tab sis qhov tsis zoo yog qhov kev nkag mus tsis muaj zog li electron beam vuam. Kev tswj xyuas lub zog meej tuaj yeem nqa tawm thaum lub sijhawm laser vuam, kom cov vuam ntawm cov cuab yeej precision tuaj yeem pom tau. Nws tuaj yeem siv rau ntau cov hlau, tshwj xeeb tshaj yog los daws cov vuam ntawm qee qhov nyuaj-rau-weld hlau thiab cov hlau tsis sib xws. Tam sim no, nws tau siv dav hauv kev kho cov pwm.
Laser cladding technology
Laser nto cladding thev naus laus zis yog kom kub ceev thiab yaj cov hmoov hlau los yog cov hmoov ceramic thiab qhov chaw ntawm lub substrate nyob rau hauv qhov kev txiav txim ntawm lub laser beam. Tom qab cov nqaj raug tshem tawm, nws tus kheej zoo siab txias ua ib txheej txheej nrog tus nqi qis heev thiab cov hlau nplaum nrog cov khoom siv substrate. , yog li txhim kho lub substrate nto hnav tsis kam, corrosion kuj, tshav kub tsis kam, oxidation tsis kam thiab hluav taws xob cov khoom ntawm ib tug nto zog txoj kev.
Piv txwv li, tom qab carbon-tungsten laser cladding ntawm 60 # steel, hardness tuaj yeem ncav cuag 2200HV, thiab hnav tsis kam yog li 20 npaug ntawm lub hauv paus 60 # steel. Tom qab laser cladding CoCrSiB alloy nyob rau saum npoo ntawm Q235 steel, nws hnav tsis kam tau muab piv nrog cov nplaim txau, thiab nws tau pom tias qhov kev tiv thaiv corrosion ntawm cov qub tau nce siab dua li yav tas los.
duab
Laser cladding yuav muab faib ua ob hom raws li cov hmoov pub mis: hmoov preset txoj kev thiab synchronous hmoov noj txoj kev. Cov teebmeem ntawm ob txoj kev zoo ib yam. Txoj kev noj cov hmoov nplej synchronous muaj qhov zoo ntawm kev tswj tsis siv neeg yooj yim, siab laser zog nqus tus nqi, thiab tsis muaj qhov pores, tshwj xeeb tshaj yog cladding cermets, uas tuaj yeem txhim kho qhov tawg tsis kam ntawm txheej cladding, kom lub zog ceramic theem tuaj yeem ua rau hauv qhov zoo ntawm kev faib tawm tsis sib xws hauv txheej txheej cladding.
1 Cov yam ntxwv ntawm laser cladding
(1) Qhov txias txias yog ceev (txog 106K / s), uas yog nyob rau hauv cov txheej txheem ceev ceev, thiab nws yog ib qho yooj yim kom tau ib tug nplua-grained qauv los yog tsim cov theem tshiab uas tsis muaj peev xwm muab tau nyob rau hauv ib tug equilibrium lub xeev, xws li tsis ruaj tsis khov theem thiab amorphous xeev;
(2) Cov txheej txheej dilution tus nqi qis (feem ntau tsawg dua 5 feem pua), thiab nws muaj kev ruaj khov metallurgical daim ntawv cog lus lossis interfacial diffusion daim ntawv cog lus nrog cov substrate. Los ntawm kev kho cov txheej txheem laser tsis, ib txheej zoo nrog tus nqi qis dilution tuaj yeem tau txais, thiab cov txheej txheem txheej txheem thiab Controllable dilution;
(3) Cov khoom siv hluav taws xob thiab qhov sib txawv me me, tshwj xeeb tshaj yog thaum siv lub zog ceev ceev ceev, qhov deformation tuaj yeem txo qis rau hauv kev sib dhos kam rau ntawm qhov chaw;
(4) Yuav luag tsis muaj kev txwv rau kev xaiv hmoov, tshwj xeeb tshaj yog rau kev tso cov hlau nplaum-melting-point alloys rau saum npoo ntawm cov hlau uas tsis tshua muaj melting point;
(5) Lub thickness ntau ntawm cladding txheej yog loj, thiab txheej thickness yog 0.2-2 0mm nyob rau hauv ib tug pass ntawm hmoov noj;
(6) Nws tuaj yeem ua qhov kev xaiv vuam, nrog cov khoom siv tsawg thiab kev ua haujlwm zoo heev;
(7) Beam aiming tuaj yeem ua rau cov chaw nkag tsis tau;
(8) Cov txheej txheem yog ib qho yooj yim rau automate, thiab nws yog heev haum rau hnav thiab tsim kua muag kho ntawm ib txwm hnav qhov chaw.
