Extrusion ntawm tooj liab pas nrig txoj kev?

1. Hom extrusion: extrusion yog muab faib ua peb hom: pem hauv ntej extrusion, thim rov qab extrusion thiab tshwj xeeb extrusion.

(1) Forward extrusion: yog hais txog extrusion cwj pwm ntawm cov khoom nyob rau hauv tib txoj kev raws li lub extrusion quab yuam.

(2) Rov qab extrusion: cov kev taw qhia extrusion yog opposite rau cov kev taw qhia ntawm extrusion quab yuam.

(3) Tshwj xeeb extrusion: yog hais txog lwm txoj kev extrusion xws li hydrostatic extrusion.

2. Cov yam ntxwv ntawm extrusion:

(1) Cov yam ntxwv ntawm kev xa mus rau pem hauv ntej extrusion: Ntawm lawv, cov khoom siv rau pem hauv ntej extrusion yog yooj yim dua thiab siv dav tshaj plaws.

(2) Cov yam ntxwv ntawm kev taw qhia extrusion: thim rov qab extrusion tuaj yeem txhim kho lub neej ntawm cov cuab yeej vim txo qhov kev sib txhuam ntawm cov ingot dawb paug thiab lub tog raj kheej extrusion, thiab txo cov extrusion quab yuam, thiab yog dav siv hauv cov khoom me me thiab nruab nrab extruded.

(3) Cov yam ntxwv tshwj xeeb extrusion: tshwj xeeb extrusion feem ntau yog siv rau extrusion ntawm cov khoom tshwj xeeb

3. Ceev faj rau extrusion:

Nyob rau hauv cov txheej txheem extrusion, lub ingot billet raug rau peb-txoj kev compressive kev nyuaj siab nyob rau hauv lub extrusion lub tog raj kheej, uas muaj peev xwm tiv taus ib tug loj npaum li cas ntawm deformation; Thaum lub sij hawm extrusion, pwm yuav tsum tsim nyog tsim thiab cov txheej txheem extrusion tsis yuav tsum tau xaiv raws li cov yam ntxwv ntawm cov hlau, cov specifications thiab cov kev cai ntawm cov khoom extruded, lub peev xwm thiab cov qauv ntawm cov khoom. Xws li cov specifications ntawm ingot, extrusion piv, extrusion kub, extrusion ceev, thiab lwm yam. Yuav kom paub meej thiab txhim kho qhov zoo ntawm cov khoom extruded, tev thiab extrusion feem ntau yog siv los tshem tawm qhov tsis xws luag ntawm qhov chaw ntawm lub ingot thaum tooj liab. alloy yog extruded.

Rau nag lossis daus-lub zog alloys, kev kho mob ua ntej txias deformation tuaj yeem ua tiav hauv cov txheej txheem extrusion los ntawm kev siv dej foob extrusion. Txhua tus kws tshaj lij tooj liab mesh tau hais tias rau cov alloys zoo tib yam, cov khoom oxidation ntawm cov khoom tuaj yeem raug txo los ntawm cov dej-sealed extrusion thiab rov qab cov khoom tuaj yeem zam tau.

Kab rov tav rau pem hauv ntej extrusion yog feem ntau cov tsoos thiab feem ntau extrusion txoj kev, thiab lub ntsiab teeb meem thaum nws squeezes cov yeeb nkab yog cov yeeb nkab core. Rov qab extrusion tsis tau tsuas yog txo cov degree ntawm eccentricity, tab sis kuj nyem ingots ntev thiab txhim kho cov yield. Vertical extrusion muaj qhov tsawg tshaj plaws eccentricity, tab sis qhov ntev ntawm cov khoom extruded yog txwv. Cov txheej txheem txuas ntxiv txuas ntxiv yog luv luv, qhov ntim hnyav, thiab nws tuaj yeem tsim cov khoom loj-ntev: nws yog qhov tshwj xeeb tshaj yog tsim rau kev tsim cov khoom tshwj xeeb-zoo li tus ntoo khaub lig-sectional khoom: cov khoom tawm los yog siab, mus txog 90-95 %: kev siv hlau tsawg dua, kev siv hluav taws xob tsawg, cov cuab yeej siv nyiaj tsawg, kev ua haujlwm hauv av me me, nws yooj yim rau kev tsim khoom tas mus li, thiab nws yog ib puag ncig zoo. Nrog rau kev ua tiav ntawm kev siv thev naus laus zis txuas ntxiv mus rau qhov dav ntawm cov khoom, txoj kev no yog nyob rau hauv txoj kev loj hlob thiab daim ntawv thov theem nyob rau hauv zus tau tej cov oxygen-dawb tooj liab thiab ntshiab tooj liab sawb. Qhov teeb meem tseem ceeb ntawm txoj kev no yog lub neej luv luv. Yuav ua li cas txhim kho pwm tsim thiab txhim kho lub neej ntawm cov khoom pwm yuav tsum tau daws.
