Aluminium alloy tuag castings yog dav siv thiab yog loj-tsim. Vim yog cov yam ntxwv ntawm aluminium alloys, peb xaiv los them sai sai rau qee qhov teeb meem thaum lub sijhawm tsim khoom. Tom ntej no, MindWell yuav qhia peb cov kev paub ntau lawm nrog koj.
1. Ua tib zoo saib cov txheej txheem vuam
Vim tias aluminium alloy tuag castings yog active thiab yooj yim oxidized thaum lub sij hawm ua hauj lwm, ib tug loj npaum li cas ntawm plua plav thiab noo noo yog ib qho yooj yim mus ua raws li qhov chaw. Yog li ntawd, thaum lub sij hawm vuam txheej txheem, cov khoom uas txuas rau saum npoo yog ib qho yooj yim kom nyob twj ywm ntawm aluminium alloy nto nrog laser vuam. , yog li cuam tshuam qhov zoo ntawm aluminium alloy thiab cov nyhuv ntawm vuam. Yog li ntawd, ua ntej welding, nws yog ib qhov tsim nyog los ntxuav lub nto ntawm aluminium alloy thiab tshem tawm cov roj stains ntawm qhov chaw. Nyob rau tib lub sijhawm, txhawm rau tiv thaiv kev ruaj ntseg hem xws li tawg los ntawm oxidation thaum vuam, nws tseem yuav tsum tau ntxuav cov oxide zaj duab xis ntawm qhov chaw.
2. Kev tshuaj xyuas zoo
Qhov zoo ntawm kev siv yog hais txog lub peev xwm ntawm castings ua hauj lwm rau lub sij hawm ntev nyob rau hauv txawv tej yam kev mob, xws li hnav tsis kam, tsis kam mus rau txias thiab kub, qaug zog, poob siab absorbing, thiab lwm yam, raws li zoo raws li cov txheej txheem xws li machinability thiab weldability. Hauv kev tsim cov casting, nws yog ib qho tsim nyog los tswj thiab tshuaj xyuas qhov zoo ntawm castings. Thaum xub thawj, nws yog ib qho tsim nyog los tsim cov txheej txheem kev cai thiab cov txheej txheem rau cov khoom siv raw, thiab cov ntaub ntawv pabcuam rau kev tswj thiab tshuaj xyuas ntawm txhua yam khoom tshwj xeeb. Txhua tus txheej txheem yog nruj me ntsis tswj thiab tshuaj xyuas raws li cov txheej txheem code thiab kev ua haujlwm. Tom qab ntawd cov tiav castings raug tshuaj xyuas kom zoo. Txhawm rau nruab nrog cov txheej txheem kuaj kom raug thiab cov neeg ua haujlwm kuaj kom tsim nyog. Feem ntau, rau qhov zoo ntawm cov castings, qhov roughness ntawm castings tuaj yeem txiav txim los ntawm cov qauv sib piv; cov kab nrib pleb zoo ntawm qhov chaw tuaj yeem kuaj xyuas los ntawm cov txheej txheem xim thiab cov txheej txheem sib nqus. Qhov zoo ntawm castings tuaj yeem raug tshuaj xyuas thiab txiav txim los ntawm lub suab, tshwj xeeb, eddy tam sim no, X-ray, thiab gamma-ray txoj kev.
3. Laser vuam
Nyob rau hauv cov txheej txheem ntau lawm, laser vuam feem ntau yog siv, thiab nws cov txhuas tuag castings yuav ntsib ntau yam teeb meem thaum lub sij hawm laser vuam, feem ntau vim hais tias nws cov aluminium alloy yog cov hlau uas tsis yog-ferrous, uas yuav txhua yam ntawm lub teeb kom muaj zog reflectivity. Raws li lub teeb hnyav dua, lub teeb laser muaj feem ntau yuav ua rau muaj kev cuam tshuam rau ntawm qhov chaw ntawm aluminium alloy.
Tsis tas li ntawd, thermal conductivity ntawm aluminium alloy ua rau nws yooj yim rau kev cuam tshuam lub laser los yog hloov lub tshav kub ntawm lub laser thaum vuam nrog lub laser, uas nws thiaj li ua rau tsis ua hauj lwm ntawm vuam ntawm aluminium alloy. Thaum laser vuam aluminium alloy, koj yuav tsum nruj me ntsis rau kev ua haujlwm thiab ua kom lub zog ceev ntawm lub laser kom tsis txhob cuam tshuam los yog kis tau. Sim welding aluminium alloy nrog lub siab ceev ntawm qhov kawg ntawm lub sijhawm, kom koj tuaj yeem zam qhov tshwm sim ntawm cov teeb meem xws li reflexivity.
4. Dab tsi cov cuab yeej yuav siv rau hauv cov txheej txheem ntawm aluminium alloy tuag castings?
- Sib tsoo thiab polishing txais yuav lub vibration sib tsoo tshuab, centrifugal polishing tshuab, thiab lwm yam khoom siv, siv lub pob zeb sib tsoo, abrasive, dej, thiab lwm yam hauv cov txheej txheem ntawm kev vibration (kev sib hloov), txhawm rau txhawm rau tiv thaiv kev tuag casting kom ua tiav cov txiaj ntsig ntawm deburring thiab polishing nto.
- Kev kho cov duab Thaum lub casting yog deformed vim solidification shrinkage, ejection deformation los yog ntug trimming, nws yog tsim nyog los kho cov duab ntawm lub deformed casting. Kev kho cov duab yuav tsum tau kho manually nrog ib tug mallet los yog nrog ib tug hydraulic xovxwm los ntawm kev ntsuas ntsuas thiab fixtures. Kev kho.
- Nyob rau hauv qhov kev txiav txim ntawm kev txhaj tshuaj-blasting log, aluminium alloy tuag-casting txhaj tshuaj-blasting projectile hits nto ntawm lub casting, ua rau nws nqus lub kinetic zog ntawm lub txav projectile thiab tsim yas deformation, qhia residual compressive kev nyuaj siab, yog li txhim kho. lub zog nto ntawm lub casting thiab tsis ntshai ntawm tsis muaj zog. Txhawm rau ua kom tiav lub hom phiaj ntawm kev ntxuav thiab sib sau ua ke.
- Sandblasting siv purified compressed cua kom muaj zog txau cov quartz xuab zeb ntws mus rau saum npoo ntawm cov casting, siv cov kev cuam tshuam thiab kev sib txhuam kom tshem tawm cov impurities xws li burrs, oxide nplai, thiab av los ntawm casting. Ntxuav lub ntsej muag ntawm cov casting thiab roughen saum npoo los txhim kho lub zog sib txuas ntawm cov txheej thiab cov substrate.
5. Tsawg-siab tuag casting
Complex aluminium alloy tuag-casting qhov chaw, xws li lub tog raj kheej taub hau, lub tog raj kheej, crankcases, thiab lub log hubs rau cov maus taus thiab tsheb, yog cov khoom tsim los ntawm cov hlau tsis tshua muaj siab, uas tsis tsuas yog txuag cov ntaub ntawv hlau thiab lub zog, tab sis kuj ua rau nws yooj yim rau kev tsim khoom thiab pwm, thiab castings. yog cov zoo. Cov ntaub ntom ntom. Lub solidification ntawm tsawg aluminium alloy tuag castings yog nqa tawm los ntawm sab saum toj mus rau hauv qab. Qhov deb ntawm lub rooj vag solidifies ua ntej, thiab maj mam txav mus rau lub rooj vag, thiab lub rooj vag solidifies. Nyob rau hauv txoj kev no, cov casting tuaj yeem dhau los ntawm kev pub mis cov qauv siv tuab ntawm lub rooj vag, yog li xoob txhuas, thiab xoob aluminium hmoov tuag-alllo tuag-cam tuag-casting. Yuav kom ua tau raws li qhov yuav tsum tau ua kom muaj zog ntawm cov saum toj no-hais qis aluminium alloy tuag castings, nws yog ib qho tsim nyog yuav tsum tau ua kom qhov kub ntawm qhov nkag thiab qhov hluav taws xob ntawm lub riser raj siab dua qhov kub ntawm lub rooj vag thiab siab dua qhov kub ntawm lub qhov hluav taws xob. kab noj hniav. Peb tau txais cov txheej txheem ntawm kev ntxiv cov cua sov tsis siv neeg thiab ntsuas kub ntawm qhov nkag thiab qhov hluav taws xob ntawm cov yeeb nkab riser los daws cov teeb meem tseem ceeb uas tau ntsib nyob rau hauv qhov tsis tshua muaj siab casting ntawm complex aluminium alloy tuag-casting qhov chaw, thiab nws tau raug pov thawj los ntawm kev nruam. loj ntau lawm xyaum hais tias cov cuab yeej yog yooj yim thiab siv tau
