Dab tsi ua rau txhuas profile los ua nkig

Aluminium Profiles yog dav siv nyob rau hauv ntau yam kev lag luam rau lawv lub teeb, corrosion kuj, thiab yooj. Txawm li cas los xij, cov embrittlement ntawm aluminium profiles yog ib qho teeb meem. Thaum lub txhuas ua brittle nrog lub hnub nyoog,Aluminium tuaj yeem ua rau tawg, pob txha, thiab txo qis dua, tshwj xeeb yog nyob rau hauv cov mob no xws li txias stamping lossis thaum raug rau ib puag ncig kev ntxhov siab.Txawm li cas los xij, cov ua rau brittleness yog multifaceted. Hauv tsab xov xwm no, peb yuav tshawb txog cov ntsiab lus tseem ceeb uas ua rau muaj nkig ua ke, thiab cov teeb meem ntawm lawv cov teeb meem no tau txhim kho.

Lub ntsiab ua rau txhuas profile brittha tsis ua tiav

Tus Brittleness ntawm Aluminium profiles tuaj yeem tshwm sim los ntawm ntau theem hauv lawv cov txheej txheem ntau lawm, los ntawm cov khoom siv Raw rau qhov kawg extrusion ...

1. Cov mis tsis tsim nyog thiab kev sib xyaw tshuab

Cov qauv tsim thiab kev sib xyaw ua ke yog qhov tseem ceeb los ua kom cov khoom xav tau yam uas xav tau ntawm cov khoom siv txhuas. Ib qho kev sib txawv ntawm cov muaj feem yuav ua rau tus profiles ua nkig. Nov yog qee qhov teeb meem tseem ceeb ntsig txog kev sib xyaw thiab tsim qauv:

•  Ntau dhau ntxiv additives: Kev siv cov neeg lim dej ntau dhau los yog cov txuas ntxiv tuaj yeem cuam tshuam rau lub zog ntawm cov profile txhuas, ua rau brittleness. Cov tub rog ntau dhau yuav cuam tshuam cov qauv molecular, tsis muaj zog tag nrho lub zog ntawm cov khoom. Tab sis, ib daim ntawv-Cawv ntawm MG ntawm Tensile deformation cwj pwm ntawm siab mg-ntsiab lus al-mg alloys[^ 1] Pom tias cov alloys nrog cov ntsiab lus magnesium siab (xws li 6061) pom a15-30%kev txhim kho hauv lub zog tensile lub zog thiab ductility thaum tsim qauv zoo nrog cov hloov kho kom tsim nyog

•  

•  Tej Yam Yuav Tsis Yooj Yim Hloov Hloov Hloov Kho: Qhov cuam tshuam Modifiers tau ntxiv los txhim kho cov tawv thiab kev tiv thaiv kom tawg kom tawg ntawm alloys alloys. Txawm li cas los xij, yog tias cov hom lossis ntau ntawm cov qauv hloov kho no tsis yog, nws tuaj yeem ua rau cov khoom lag luam tsis zoo, tshwj xeeb hauv cov khoom lag luam txias.

•  

•  Tsis yog Stabilizer kom muaj nuj nqis: Lub stabilizer yog siv los txhim kho cov khoom siv ntawm alloy, xws li nws txoj kev tiv taus corrosion. Ntau dhau los yog me me stabilizer tuaj yeem cuam tshuam cuam tshuam rau cov khoom siv lub zog, ua rau brittleness.

•  

•  Ntau dhau los yog tsis txaus roj: Kev siv lubricalt tsis raug rau thaum lub sijhawm ua kom tsis muaj zog yuav ua rau kom tsis muaj txiaj ntsig ntawm cov lwg me me, ua rau cov khoom yuav tsum tau sib tsoo.

2. Tsim tsis tau cov txheej txheem extrusion

Qhov txheej txheem Extrusion yog ib theem tseem ceeb tshaj plaws hauv txhuas profile. Yog tias cov txheej txheem tsis ua tib zoo tswj, nws tuaj yeem ua rau tus profitttitly scittle uas ib txwm ua kom tawg lossis ua tsis tiav. Qee qhov teeb meem tshwm sim thaum lub sijhawm extrusion suav nrog:

 Ntau dhau los lossis tsis txaus yas: Yas tshuab[^ 2] yog hais txog qhov muag muag ntawm cov txhuas kom ua rau nws manicle. Yog tias cov khoom siv dhau mus- lossis hauv qab-rhuab thaum lub sijhawm extrusion, nws tuaj yeem ua rau kev sib koom ua tsis zoo ntawm cov lwg me me, nce brittleness.

•  

•  Tsawg Extrusion Siab Siab: Tsis muaj peev xwm thaum lub sijhawm extrusion tuaj yeem ua rau cov profiles tsis muaj zog nrog qhov tsis sib xws. Qhov no tuaj yeem ua rau thaj chaw ntawm cov ntaub ntawv ntawm cov ntaub ntawv kom muaj ntau dua kis tau txhawm rau tawg kom ntxhov siab.

•  

•  Kev tshem tawm tsis txaus ntawm cov roj av tsawg: Cov khoom siv molecular tsawg tuaj yeem ua rau cov ntsiab lus tsis muaj zog nyob rau hauv cov profile txhuas. Yog tias lawv tsis raug tshem tawm kom zoo thaum lub sijhawm ua kom tiav, qhov profile yuav muaj cov khoom sib txawv, ua rau brittleness.

•  

•  Mismatch ntawm traction thiab extrusion ceev: Qhov ceev ntawm qhov profile yog rub (traction) yuav tsum phim qhov ceev ntawm qhov kev sib tw. Ib qho tsis muaj peev xwm ua rau cov khoom siv tsis sib xws, uas tuaj yeem ua rau cov pob hluav taws uas tsis muaj zog uas ua rau tawg. Ib qho kev ua tau zoo rau cov txheej txheem kom zoo tuaj yeem nce cov kev pabcuam lub neej ntawm txhuas profiles los ntawmTxog li 50%, tshwj xeeb tshaj yog rau cov ntawv thov siab ua haujlwm

3. Tsis tsim nyog pwm tsim

Pwm Tsim yog lwm qhov tseem ceeb tshwm sim uas cuam tshuam rau cov khoom siv tshuab ntawm Aluminium Profiles. Ib qho kev tsim qauv pwm tsis zoo yuav ua rau cov teeb meem xws li kev ntxhov siab, tsis sib xws cov khoom ntws, thiab txias tsis sib xws, tag nrho cov uas ua rau muaj kev kub ntxhov. Nov yog qee qhov teeb meem tseem ceeb nrog cov qauv pwm:

•  Hla Kev Tsim Qauv: Tus qauv tsim ntawm DE DOG CROSE-seem, tshwj xeeb yog kev kho ntawm cov ces kaum sib cuam tshuam, yog qhov tseem ceeb los tiv thaiv kev ntxhov siab. Cov ces kaum ntse los yog txoj cai cov ces kaum hauv cov pwm tuaj yeem ua rau tawg thiab tsis muaj zog hauv qhov profile.

•  

•  Tsis muaj kev tuag siab: Lub siab thov rau ntawm lub taub hau tuag cuam tshuam rau cov khoom ntws. Lub siab tsis tshua muaj peev xwm ua rau cov txhuas kom tsis ntws yooj yim los ntawm cov pwm, ua rau muaj qhov tsis muaj zog profile. Kho qhov piv rau Compression hauv cov pwm tsim yog ib txoj hauv kev los ua kom zoo tuag siab tuag siab.

• 

•  Tsis zoo kub yaj: Yog tias cov kab txhuas txhuas tsis yaj kom zoo lossis ntws tau cuam tshuam, lub txiaj ntsig profile yuav muaj cov khoom tsis zoo. Txhawm rau hais txog qhov teeb meem no, nce cov qhab nia tseem ceeb lossis qhov ntev ntawm qhov bar tuaj yeem pab ua kom cov khoom txaus txaus.

•  Tsis ncaj ncees tuag tawm: Yog tias tus tuag tsis tawm cov ntaub ntawv txhuas kom loj hlob, lub txiaj ntsig profile yuav muaj cov phab ntsa tuab lossis ntom ntom ntom. Qhov no tuaj yeem ua rau cov chaw tsis muaj zog uas nquag tsis muaj kev ntxhov siab.

•  Tus nqi uas tsis tsim nyog: Tustxias tus nqi ntawm uas cov txhuas txias tom qab extrusion[^ 3] Ua ib lub luag haujlwm tseem ceeb hauv cov ntaub ntawv zaum kawg ntawm cov khoom. Tus nqi txias lossis tsis sib xws tuaj yeem ua rau muaj kev sib cav sib ceg tsis zoo, ua rau cov khoom siv ntau ntxiv. Cov dej txias txias feem ntau saib xyuas hauv cov txheej txheem ntau lawm, tab sis nws plays lub luag haujlwm tseem ceeb hauv kev ua tiav cov khoom xav tau ntawm cov profile txhuas.

Ntau hom ntawm txhuas alloy: 6061, 6063, thiab 7075

Xaiv txoj cai txhuas alloy rau koj cov khoom yog qhov tseem ceeb rau kev ua tiav cov khoom siv uas xav tau, suav nrog lub zog uas xav tau, nrog rau kev tawm tsam. Cov ntaub ntawv nthuav tawm hauv qab no yuav pab koj xaiv cov khoom zoo tshaj plaws raws li koj cov khoom xav tau tshwj xeeb.

 6061 Aluminium: Qhov no yog ib qho ntawm feem ntau ntau yam thiab feem ntau siv cov aluminium alloys. Nws lub zog siab thiab kev ua haujlwm zoo corrosion ua rau nws zoo rau cov kev thov, xws li nyob rau hauv thav duab, kab teeb, thiab lwm cov ntawv thov hnyav.

 6061 Aluminiumtuaj yeem ua tiav apaib lub zog ntawm 290 mpaThiab yog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum muaj ob qho muaj zog thiab lub tshuab luam ntawv. Yog tias koj xav tau kev sib npaug ntawm lub zog thiab ua haujlwm,6061Yog kev xaiv cov khoom siv rau cov khoom lag luam dav dav xws li cov khoom lag luam lossis cov qauv txheej txheem hauv cov tuam tsev.
 

•  6063 txhuas: Paub txog nws cov haujlwm tau zoo, 6063 txhuas feem ntau siv hauv cov ntawv thov uas xav tau ib qho kev ua kom tiav thiab zoo corrosion. Nws yog feem ntau pom nyob rau hauv cov ntawv thov archectural, lub qhov rais thav ntawv, thiab cov kev tsheb nqaj hlau, qhov twg pom thiab ruaj khov yog qhov tseem ceeb. 6063 muaj lub zog qis tshaj plaws piv rau 6061 (290-310 mpa), tab sis nws cov elongation siab thaum so (Txog li 18%) Ua rau nws zoo tagnrho rau cov khoom lag luam uas yuav tsum tau extruded thiab puab yooj yim.
   

•  7075 Aluminium: Yog tias koj cov khoom muaj kev ntxhov siab ntau, xws li hauv Aerospace, tub rog, lossis kev ua haujlwm siab engineering, 7075 txhuas yog qhov sib txawv ntawm kev xaiv. Qhov no alloy muaj lub zog siab tshaj plaws ntawm peb, mus txog503 MPaCov. Txawm li cas los xij, nws yog qhov nyuaj rau lub tshuab thiab muaj qis dua corrosion tsis kam tshaj 6061 lossis 6063. 7075 yog qhov zoo tshaj plaws rau cov khoom lag luam uas muaj zog tshaj plaws, xws li cov khoom siv dav hlau lossis cov tub rog-cov tub rog.
