Koj tau teev lub siab -lub zog aluminium alloy rau cov khoom tseem ceeb, tab sis nws ua tsis tiav thaum kuaj lossis hauv thaj teb. Qhov kev tsis sib haum xeeb no ua rau kev ua haujlwm kim dua thiab ua rau koj lub koob npe nrov rau kev ntseeg siab.

Tus lej alloy yog cov lus cog tseg ntawm lub zog; peb cov txheej txheem forging yog qhov lav. Peb tsim cov qauv hauv cov nplej kom qhib cov khoom siv tag nrho, xa cov kev kwv yees, kev ua haujlwm ntau qhov chaw uas cov qauv tsis ua haujlwm, ua kom koj cov khoom muaj kev ncaj ncees.

Kuv nco qab ua haujlwm nrog ib tus neeg siv khoom tshiab uas tau tsim cov khoom siab tshaj -kev ua haujlwm raug ncua rau lub tsheb tom qab kev lag luam. Lawv tau machining qhov chaw los ntawm 7075-T6 extruded bar Tshuag. Ntawm daim ntawv, nws yog cov khoom siv zoo-ib qho ntawm cov khoom siv txhuas muaj zog tshaj plaws. Txawm li cas los xij, lawv tau pom qhov tsis sib xws ntawm kev qaug zog ua tsis tiav. Qee qhov chaw yuav nyob mus ib txhis, thaum lwm qhov yuav tawg ntxov ntxov. Qhov teeb meem tsis yog 7075 alloy; nws yog daim ntawv. Cov txheej txheem extrusion tsim cov qauv nplej uas khiav hauv txoj kab ncaj nraim. Cov duab nyuaj ntawm lawv feem txhais tau hais tias kev ua haujlwm ua haujlwm txiav hla cov nplej no, tsim cov ntsiab lus tsis muaj zog. Peb hloov lawv mus rau kev siv cov kev cai ze-net zoo li forging. Peb tsim cov txheej txheem forging los ua kom cov nplej ntws raws li cov contours ntawm qhov kawg. Cov kev ua tsis tiav tau nres tag nrho vim hais tias feem ntawm lub zog yog tam sim no zoo ib yam thiab multidirectional.

Puas yog forged aluminium tiag tiag muaj zog dua tus qauv txhuas?

Koj muaj ob qhov chaw ua los ntawm tib yam alloy, 6061-T6. Ib tug yog machined los ntawm ib tug cam khwb cia block, lwm yam los ntawm forged block. Qhov cam khwb cia tsis ua haujlwm, tab sis tus forged tuav tau.

Yog lawm, forged aluminium yog qhov muaj zog thiab txhim khu kev qha ntau dua li cam khwb cia lossis extruded aluminium ntawm tib lub alloy. Cov txheej txheem forging tshem tawm cov teeb meem sab hauv thiab tsim kom muaj cov khoom ua kom zoo, tsis tu ncua cov nplej uas txhim kho nws cov tawv tawv thiab qaug zog.

Lo lus "aluminium" tsis qhia tag nrho zaj dab neeg. Txoj kev tsim khoom hauv paus hloov cov khoom siv. Ib qho cam khwb cia yog tsim los ntawm kev nchuav hlau molten rau hauv pwm. Raws li nws txias, microscopic voids thiab lub hnab ntim roj tuaj yeem raug daig, thiab cov qauv nplej yog ntxhib thiab random. Cov teeb meem no dhau los ua - hauv cov ntsiab lus tsis muaj zog. Extrusion txhim kho qhov no los ntawm kev thawb lub pob zeb los ntawm kev tuag, uas tsim cov kab lis kev cai ntws, tab sis qhov no tuaj yeem yog qhov tsis muaj zog yog tias qhov kawg muaj kev ntxhov siab siv los ntawm ntau cov lus qhia. Forging yog txawv. Peb siv lub zog compressive loj heev los tsim cov hlau. Cov txheej txheem no lub cev kaw cov voids sab hauv, tsim kom muaj 100% cov khoom ntom ntom. Nws kuj rhuav tshem cov pob zeb coarse thiab refines nws, ua kom nws zoo kawg nkaus thiab tawv. Qhov no refined, interlocked grain qauv dramatically tsub kom cov khoom ' s tsis kam mus rau tej yam thiab qaug zog. Yog li, thaum lub chemistry yog tib yam, cov qauv kev ncaj ncees ntawm ib feem forged yog nyob rau hauv ib tug sib txawv kiag li pab koomtes.

Rau lub zog siab, koj yuav tsum xaiv 6061 lossis 7075 txhuas?

Koj xav tau lub siab -lub zog aluminium. Koj pom tias 7075 muaj zog dua 6061, tab sis tus nqi tseem ceeb sib txawv ua rau koj nug yog tias qhov kev ua tau zoo ntxiv yog tsim nyog rau tus nqi.

7075-T6 aluminium yog qhov muaj zog heev, nrog ze li ob npaug ntawm cov txiaj ntsig ntawm 6061-T6. Nws yog qhov kev xaiv zoo tshaj plaws rau lub zog siab tshaj plaws - rau daim ntawv thov hnyav. Txawm li cas los xij, 6061-T6 yog cov khoom siv ntau yam, raug nqi zoo.

Qhov no yog cov lus nug tseem ceeb rau ntau ntawm peb cov neeg siv khoom machining. Ob leeg 6061 thiab 7075 yog cov cua kub zoo heev- kho tau cov alloys, tab sis lawv ua hauj lwm sib txawv . 6061-T6 yog lub workhorse ntawm kev lag luam. Nws muaj kev sib xyaw ua ke zoo heev ntawm lub zog zoo, zoo heev corrosion kuj, weldability, thiab tus nqi. Nws yog qhov mus- mus rau cov khoom siv rau ntau yam ntawm cov qauv siv, los ntawm lub hauv paus tshuab mus rau qhov chaw tsheb. 7075-T6 yog ib qho tshwj xeeb aerospace alloy. Nrog zinc ua nws cov ntsiab lus alloying, nws tuaj yeem ua kom sov- kho kom ua tiav qhov muaj zog piv rau qee cov hlau, tab sis ntawm ib feem peb ntawm qhov hnyav. Qhov no ua rau nws tseem ceeb rau cov ntawv thov uas tsis ua haujlwm tsis yog qhov kev xaiv thiab txhua qhov suav suav, xws li cov dav hlau tsaws iav lossis siab -cov khoom sib tw ua haujlwm. Qhov kev ua tau zoo tshaj plaws no los ntawm tus nqi siab dua thiab nrog qis corrosion kuj. Rau peb, cov lus pom zoo yog qhov tseeb: pib nrog 6061 rau kev siv siab -kev ntxhov siab. Tsuas yog txav mus rau 7075 thaum koj tau thawb cov kev txwv ntawm 6061 thiab xav tau lub zog siab tshaj plaws.

 

Puas yog 5052 lossis 6061 aluminium muaj zog dua?

Koj pom tias 5052 hu ua "marine- qib" thiab paub txog nws qhov tawv. Qhov no ua rau koj xav tsis thoob yog tias nws yog qhov kev xaiv muaj zog thiab zoo dua rau kev xav tau cov khoom siv ntau dua li tus qauv 6061 alloy.

Tsis yog, 6061-T6 muaj zog ntau dua li txhua qhov kub ntawm 5052 txhuas. 5052 yog ib qho uas tsis yog-tshuaj kub-kho alloy muaj nuj nqis rau nws qhov zoo heev formability thiab corrosion kuj, tsis yog nws lub zog siab rau machined qhov chaw.

Nws yog ib qho yuam kev ua rau tsis meej pem toughness lossis corrosion kuj nrog lub zog. Cov alloys no yog rau ob tsev neeg sib txawv. 6061 yog cov cua sov- kho tau los ntawm 6xxx series. Nws lub zog yog "xauv" los ntawm T6 cov txheej txheem kho cua sov, uas ua rau nws nyuaj thiab muaj zog, zoo meej rau kev ua haujlwm ntawm cov khoom siv. 5052 yog ib qho uas tsis yog- cua sov- kho tau alloy los ntawm 5xxx series. Nws tau txais nws lub zog tsuas yog los ntawm strain hardening (ua hauj lwm hardening), zoo li thaum nws dov rau hauv ib daim ntawv. Nws cov txiaj ntsig tseem ceeb yog nws lub peev xwm zoo kawg uas yuav tsum tau khoov thiab tsim yam tsis muaj kev tawg thiab nws cov kev tiv thaiv zoo tshaj rau corrosion, tshwj xeeb tshaj yog nyob rau hauv dej ntsev. Qhov no ua rau nws zoo tagnrho rau cov ntawv hlau xws li nkoj hulls, roj tso tsheb hlau luam, thiab chassis panels. Koj yuav siv 5052 daim ntawv los ua ib qho nyuaj, tab sis koj yuav siv 6061 forged bar los tshuab muaj zog, thauj khoom-cov kabmob. Rau txhua daim ntawv thov uas xav tau lub zog siab los ntawm cov khoom thaiv lossis bar, 6061-T6 yog qhov kev xaiv zoo tshaj plaws.

 

Puas yog 6061-T6 aluminium forged?

Koj paub tias koj xav tau 6061-T6 rau koj qhov, tab sis koj tsis paub tseeb tias "forged" yog cov khoom sib txawv. Koj pom "6061-T6 Forged Ring" thiab xav tias nws yog hom tshwj xeeb ntawm 6061.

Qhov no yog ib qho kev tsis meej pem . 6061 yog cov hlau. T6 yog kev kho cua sov. Forged yog cov txheej txheem tsim khoom. Koj tuaj yeem muaj 6061-T6 hauv cam khwb cia, extruded, lossis forged daim ntawv.

Cia peb tawg qhov no, vim nws yog qhov tseem ceeb rau kev qhia koj cov khoom kom raug. Xav tias nws yog peb daim ntawv qhia -ib feem rau koj cov khoom zaum kawg:

Alloy (Cov khoom xyaw):Qhov no yog cov tshuaj muaj pes tsawg leeg. Nyob rau hauv cov ntaub ntawv no, 6061, uas yog ib tug txhuas alloy nrog magnesium thiab silicon raws li nws lub ntsiab ntxiv. Qhov no txhais cov khoom muaj peev xwm.

Txheej txheem (Cov txheej txheem ua noj):Qhov no yog li cas tus raw billet yog zoo li tus. Nws tuaj yeem cam khwb cia (pob), extruded (pushed), los yog forged (nias hauv qab lub zog loj). Cov txheej txheem no txiav txim siab lub suab sab hauv thiab cov qauv nplej. Qhov no yog qhov SWA Forging ntxiv tus nqi tseem ceeb.

Qhov no yog kev tshaj tawm - kev kho mob, feem ntau yog kev kho cua sov, uas ua rau cov khoom siv kho kom zoo. T6 temper yog ib qho tshwj xeeb ob -kev kho cua sov uas ua rau 6061 ua tiav nws lub zog zoo thiab qhov tawv.

Yog li, "6061-T6 Forged Ring" los ntawm peb txhais tau tias koj tau txais kev ntseeg siab 6061 alloy, ntxiv dag zog rau nws lub ncov T6 mob, thiab tsim siv cov txheej txheem forging superior los lav nws txoj kev ncaj ncees.

 

Xaus

Tsis txhob cia li qhia ib qho alloy; qhia cov txheej txheem. Xaiv SWA Forging kom ntseeg tau tias koj lub siab - lub zog aluminium muaj qhov kev lees paub ntawm kev ncaj ncees thiab kev tsim cov qauv nplej uas xav tau los ua qhov tsis muaj qhov tsis txaus ntseeg.
