Txheej txheem cej luam ntawm 7075-T6 Aluminium
7075 yog ib qho txhuas-zinc-magnesium- tooj liab alloy tsim rau cov qauv dav hlau, thiab T6 temper yog nws cov cua sov tshaj plaws- kho mob. Tom qab kev kho cua sov kho thiab kev laus laus, 7075-T6 nce mus txog ib qho ntawm cov qib siab tshaj plaws muaj nyob rau hauv cov ntawv txhuas txhuas thiab phaj, nrog lub zog tensile zoo nyob rau hauv 510-570 MPa ntau yam. Lub alloy muaj qhov zoo tshaj plaws lub zog-rau-qhov hnyav piv, ua rau nws zoo tagnrho rau cov khoom uas raug kev nyuaj siab heev uas qhov hnyav yuav tsum tau txo qis.
T6 thiab T651 Tempers piav qhia
T6 qhia txog kev kho cua sov ua raws li kev laus laus, uas ua rau lub zog siab tshaj plaws los ntawm nag lossis daus hardening. T651 ntxiv kev tswj kev ncab cov kauj ruam tom qab kev kho mob thiab ua ntej kev laus, tshem tawm cov kev ntxhov siab seem kom lub phaj tseem nyob ruaj khov thaum lub sijhawm ua haujlwm hnyav. Rau precision Cheebtsam, saw- txiav los yog machined qhov chaw, thiab nruj- kam rau ua fabrications, T651 feem ntau yog nyiam vim nws txo qis distortion thaum cov khoom raug tshem tawm. Ob leeg tempers muaj nyob rau hauv daim ntawv thiab phaj, thiab ob leeg ua raws li tsoom fwv teb chaws thiab kev lag luam specifications rau cov alloy.
Lub zog thiab cov txiaj ntsig tseem ceeb
Cov txiaj ntsig tseem ceeb ntawm 7075-T6 yog nws lub zog tshwj xeeb ua ke nrog txhuas lub teeb yuag. Cov ntsiab lus zinc siab ua kom muaj zog, ua rau cov khoom tiv taus ntau dua rau kev tawg thiab corrosion dua li lwm cov alloys siab. Lub alloy kuj qhia tau hais tias muaj zog qaug zog zoo, uas yog vim li cas nws tseem yog tus qauv rau cov dav hlau thauj khoom thiab cov khoom siv tshuab. Nws tuaj yeem tsim nyob rau hauv cov xwm txheej annealed thiab tom qab ntawd kho cua sov kom ua tiav cov khoom siv kho tshuab uas xav tau, tso cai rau cov duab nyuaj tsim ua ntej qhov kawg hardening.
Tej kev siv
7075-T6 phaj yog dav siv nyob rau txhua qhov chaw siab tshaj plaws yog qhov tseem ceeb: airframe qauv, tis thiab fuselage Cheebtsam, siab -load mechanical qhov chaw, pneumatic thiab hydraulic cov cuab yeej, cuab yeej thiab pwm phaj, thiab tiv thaiv-khoom kho vajtse. Cov hlau tseem muaj nyob rau hauv daim ntawv thiab ntim cov tshuab tsim khoom, qhov chaw tiaj tiaj yuav tsum tuav qhov ruaj khov nyob rau hauv kev rov ua dua. Kev cai txhuas extrusion nyob rau hauv 7075 yog nce ntxiv nrog saw-txiav tiav uas muaj cov tswv yim zoo tshaj tag nrho machined nto rau tej yam ntxwv thiab sib dhos daim ntaub ntawv.
Fabrication Notes
Spot welding thiab flash welding yog ua tau nrog 7075-T6, thaum arc vuam thiab roj vuam feem ntau tsis pom zoo vim tias thaj chaw muaj kev kub ntxhov poob lub zog thiab ua rau tawg. Rau kev sib dhos, mechanical fasteners, rivets, lossis adhesive bonding yog cov qauv txheej txheem. Machining ua tau zoo nrog cov cuab yeej ntse carbide thiab coolant, thiab pom txiav nrog cov khoom noj kom zoo ua kom huv si haum rau kev ua haujlwm ntxiv. Thaum kawg cov duab yuav tsum tau khoov, txoj kev yuav tsum tau ua nyob rau hauv lub annealed mob thiab lub tshav kub kho tom qab.
Cov txheej txheem thiab cov ntaub ntawv xaj xaj
7075-T6 txhuas phaj ua raws li tsoomfwv cov lus qhia QQ-A-225/9, thiab cov ntawv thiab phaj cov khoom tseem raug them los ntawm ASTM B209 thiab AMS-QQ-A-250/12. Thaum thov cov lus hais, cov neeg yuav khoom yuav tsum qhia meej alloy, temper, thickness, dav, ntev, deg mob, thiab tus txheej txheem tswj. Rau cov ntawv thov precision, thickness kam rau ua thiab flatness yuav tsum tau lees paub nrog tus neeg muag khoom, thiab daim ntawv pov thawj zeb yuav tsum tau thov kom paub tseeb tias muaj pes tsawg leeg thiab cov khoom siv tshuab.
FAQ
Q: Qhov txawv ntawm 7075-T6 thiab T651 yog dab tsi?
A: T651 tau txais kev tswj hwm kev ncab ntxiv tom qab kev daws teeb meem los daws kev ntxhov siab sab hauv, uas txhim kho qhov kev ruaj ntseg thaum lub sij hawm machining. Mechanical zog yeej tseem zoo tib yam.
Q: 7075-T6 puas tuaj yeem welded?
A: Spot thiab flash welding yog ua tau, tab sis arc thiab roj welding feem ntau tsis pom zoo vim tias cov cua sov- cuam tshuam thaj tsam poob lub zog thiab ua rau tawg.
Q: Cov ntawv thov twg haum rau 7075-T6 phaj zoo tshaj?
A: Cov khoom muaj kev ntxhov siab heev uas lub zog- rau- qhov hnyav piv yog qhov tseem ceeb: cov qauv dav hlau, siab- cov khoom siv thauj khoom, cov cuab yeej, cov khoom siv pneumatic thiab hydraulic, thiab cov khoom siv tiv thaiv.
Q: Dab tsi specification npog 7075-T6 phaj?
A: Tsoom Fwv Teb Chaws specification QQ-A-225/9, nrog ASTM B209 thiab AMS-QQ-A-250/12 kuj npog cov ntawv thiab phaj khoom.
Q: Puas yog 7075-T6 tiv taus corrosion ntau dua li lwm cov alloys muaj zog?
A: Cov ntsiab lus zinc siab txhim kho qhov tawv thiab tiv thaiv kev tawg thiab corrosion piv nrog qee qhov siab -lub zog alloys, tab sis 7075 tseem xav tau kev tiv thaiv tiav hauv qhov hnyav lossis dej hiav txwv.
Q: 7075 puas tuaj yeem tsim thiab tom qab ntawd tawv?
A: Yog. Cov hlau tuaj yeem tsim nyob rau hauv qhov kev mob annealed thiab tom qab ntawd cov tshuaj kho cua sov thiab hnub nyoog kom ncav cuag qhov xav tau T6 cov khoom.
