Dab tsi yog cov ntaub ntawv ntawm cov pas nrig tooj liab?
Cov khoom siv tooj liab muaj xws li H59, H59-1, H59-2, H59-3, H60, H60-2, H62, H63, H65, H68, H70, H80, H90; C1100, C1020, C2680, C2800, C2600, C2801, C5191, C5210, C2200, C7521, C7541, C17200, C1070, C7701, QSn6.{{28}n.{3, QSn. 32}}.3, BZn18-18, BZn15-20, CuBe2, thiab lwm yam.
Ua ntej qhia txog cov txheej txheem ntawm cov pas nrig tooj liab thiab ntws, peb tham txog cov txheej txheem hlau ua.
1. Hlau solidification forming feem ntau hu ua casting. Casting yog txheej txheem ntawm pouring, txhaj tshuaj los yog nqus hlau molten rau hauv pwm kab noj hniav, thiab tau txais ib tug casting nrog ib tug tej yam zoo thiab kev ua tau zoo tom qab nws solidifies.
2. Kev tsim cov yas hlau yog ib txoj kev ua haujlwm uas siv cov yas deformation muaj peev xwm ntawm cov ntaub ntawv hlau los ua cov ntaub ntawv hlau tsim cov yas deformation raws li qhov kev txiav txim ntawm sab nraud quab yuam kom tau txais qhov chaw lossis qhov khoob nrog qee yam duab, qhov ntau thiab tsawg thiab cov khoom siv tshuab. Nws cov txheej txheem feem ntau tuaj yeem muab faib ua dawb forging, tuag forging, ntawv hlau stamping, extrusion, nias, thiab lwm yam. Qhov zoo ntawm forging yog feem ntau ntsuas los ntawm ob qhov ntsuas: lub plasticity thiab deformation kuj ntawm cov hlau. Yog hais tias lub plasticity siab thiab deformation kuj yog tsawg, cov cuab yeej forging yog zoo; txwv tsis pub, cov cuab yeej forging yog pluag.
3. Hlau vuam txheej txheem. Vuam yog ib txoj kev tsim uas ua tiav atomic bonding ntawm cov ntaub ntawv hlau los ntawm cua sov los yog pressurizing los yog ob qho tib si, thiab nrog los yog tsis muaj cov ntaub ntawv sau. Nws feem ntau muab faib ua fusion vuam, siab vuam, thiab brazing.
Dab tsi yog cov txheej txheem kev tsim cov pas nrig tooj liab? Muaj ntau ntau txoj kev ua tooj liab, suav nrog extrusion, dov, nruam casting, ncab, thiab lwm yam.
Copper pas nrig txoj kev khiav? Muaj peb hom tooj liab pas nrig ua cov txheej txheem ntws, raws li hauv qab no
1. Nias-(rolling)-stretching-(annealing)-finishing-tiav khoom.
2. Nruam casting (nce, kab rov tav lossis log, crawler, impregnation)-(rolling)-stretching-(annealing)-cov khoom tiav
3. Nruam extrusion-stretching-(annealing)-cov khoom tiav-cov khoom tiav.
Extrusion ntawm tooj liab pas nrig txoj kev?
1. Hom extrusion: Extrusion muab faib ua peb hom: pem hauv ntej extrusion, thim rov qab extrusion thiab tshwj xeeb extrusion.
(1) Forward extrusion: hais txog tus cwj pwm extrusion nyob rau hauv uas extrusion kev taw qhia ntawm cov khoom yog tib yam li extrusion quab yuam kev taw qhia.
(2) Rov qab extrusion: cov extrusion kev taw qhia yog opposite rau extrusion quab yuam kev taw qhia.
(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 extrusion pem hauv ntej yog qhov yooj yim thiab siv dav tshaj plaws.
(2) Cov yam ntxwv ntawm kev taw qhia extrusion: Rov qab extrusion txo qhov kev sib txhuam ntawm cov ingot thiab cov extrusion chim, txo cov extrusion quab yuam, thiab tuaj yeem ua rau lub neej ntawm cov cuab yeej. Nws yog dav siv nyob rau hauv me me thiab nruab nrab-qhov loj me extruded khoom.
(3) Cov yam ntxwv tshwj xeeb extrusion: Tshwj xeeb extrusion feem ntau yog siv rau extrusion ntawm cov khoom tshwj xeeb (raws li qhia hauv daim duab).
3. Ceev faj rau extrusion:
Thaum lub sij hawm extrusion txheej txheem, lub ingot yog raug rau peb-dimensional compressive kev nyuaj siab nyob rau hauv lub extrusion chim thiab 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 technical specifications ntawm cov khoom extruded, thiab lub peev xwm thiab cov qauv ntawm cov khoom. Xws li cov specifications ntawm lub ingot, extrusion piv, extrusion kub, extrusion ceev, thiab lwm yam. Nyob rau hauv thiaj li yuav xyuas kom meej thiab txhim kho lub nto zoo ntawm cov khoom extruded, tooj liab alloys feem ntau extruded los ntawm tev extrusion kom tshem tawm qhov tsis xws luag nyob rau saum npoo ntawm lub ingot.
Rau nag lossis daus-lub zog alloys, dej foob extrusion tuaj yeem siv los ua kom tiav cov txheej txheem kho ua ntej txias deformation hauv txheej txheem extrusion. Quantong.com cov kws tshaj lij tau hais tias rau cov hlau zoo tib yam, dej foob extrusion tuaj yeem txo qhov oxidation ntawm cov khoom thiab tsis txhob rov qab cov khoom.
Kab rov tav rau pem hauv ntej extrusion yog feem ntau cov tsoos extrusion txoj kev. Nws qhov teeb meem tseem ceeb thaum extruding ib lub raj yog ob qhov chaw ntawm lub raj. Rov qab extrusion tsis tau tsuas yog txo cov degree ntawm eccentricity, tab sis kuj extrude ntev ingots thiab txhim kho tus nqi yield. Vertical extrusion muaj qhov lightest degree ntawm eccentricity, tab sis qhov ntev ntawm cov khoom extruded yog txwv. Cov txheej txheem txuas ntxiv txuas ntxiv yog luv luv, yob hnyav, thiab cov khoom siv ntev tuaj yeem tsim tau: nws yog tshwj xeeb tshaj yog haum rau kev tsim cov khoom tshwj xeeb zoo li tus ntoo khaub lig-section: cov khoom lag luam tawm tus nqi siab, mus txog 90-95% : kev siv hlau tsawg, kev siv hluav taws xob tsawg, cov cuab yeej siv me me, cov hneev taw me me, yooj yim rau kev tsim khoom tas mus li, thiab ib puag ncig zoo. Nrog rau kev ua tiav ntawm kev siv thev naus laus zis txuas ntxiv mus rau hauv cov khoom dav, 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 strips. Qhov teeb meem tseem ceeb ntawm txoj kev no yog qhov pwm lub neej luv luv. Yuav ua li cas txhim kho pwm tsim thiab ua kom lub neej ntawm cov khoom pwm yuav tsum tau daws.
Rolling ntawm tooj liab pas nrig txoj kev? Muaj peb hom tooj liab dov: qhov dov, spinning dov thiab planetary dov.
Stretching ntawm tooj liab pas nrig txoj kev?
1. Lub ntsiab lus ntawm kev ncab: Kev ncab yog txoj kev ua haujlwm siab uas hla qhov khoob ntawm qhov tuag thiab siv qhov nro los hloov nws cov duab thiab qhov loj. Nws kuj yog ib txoj hauv kev tseem ceeb rau kev tsim cov tooj liab hlau ua tiav.
2. Cov yam ntxwv ntawm kev ncab: Los ntawm cov txheej txheem no, cov duab thiab qhov loj ntawm cov khoom ua tau raws li qhov yuav tsum tau ua, thiab nws muaj cov yam ntxwv ntawm qhov siab qhov tseeb thiab qhov chaw zoo.
3. Qws hlau stretching yog txoj kab uas hla txo stretching: Lub stretching ntawm cov kav dej yog muab faib ua txoj kab uas hla expansion stretching, txoj kab uas hla txo stretching thiab txoj kab uas hla txo thiab phab ntsa txo stretching. Cov tub ntxhais lub taub hau cov ntaub ntawv ntawm cov yeeb nkab ncab muaj xws li lub taub hau ruaj khov, cov tub ntxhais ntab taub hau thiab cov pas nrig ntev. Saib daim duab schematic rau ntau txoj hauv kev nthuav dav
Thaum lub taub hau ntab ntab yog ncab, lub zog sib npaug tsim los ntawm cov duab ntawm cov tub ntxhais lub taub hau ua rau nws ruaj khov hauv thaj tsam deformation. Txoj kev no muaj qhov loj elongation coefficient ib kis, txoj kab uas hla loj txo thiab txo phab ntsa, thiab tsim nyog rau kev tsim cov kav dej ntev thiab coils. Tsau core taub hau stretching yuav tsum tau ib tug tub ntxhais pas nrig kom cov tub ntxhais lub taub hau stably nyob rau hauv lub deformation cheeb tsam, uas yog tsuas yog siv rau zus tau tej cov cov kav dej ncaj.
Cov cuab yeej siv dav siv feem ntau suav nrog saw stretching tshuab, disc stretching tshuab, hydraulic stretching tshuab thiab ua ke stretching tshuab. Chain stretching tshuab yog tsuas yog siv rau stretching ncaj sawb cov khoom, thiab muab faib ua ib leeg-chain, ob-chain thiab ib-kab, multi-line stretching tshuab. Disc stretching tshuab yog tsuas yog siv rau zus tau tej cov me me thiab nruab nrab txoj kab uas hla discs: ua ke stretching tshuab yog tsuas yog siv rau zus tau tej cov me me ncaj strip cov khoom los ntawm discs mus rau taag ntev, thiab muaj peev xwm ib txhij ncav cuag stretching, straightening, nto polishing, thiab tsau-ntev shearing ntawm cov khoom, thiab ncaj qha tsim cov khoom tiav.
