Txog tooj liab pas nrig txoj kev siv tshuab thiab txheej txheem, tooj liab pas nrig extrusion ceev faj, tooj liab pas nrig txoj kev kho cua sov thiab cov txheej txheem txheej txheem, thiab lwm yam.
1. Cov pas nrig tooj liab
Dab tsi yog cov khoom siv 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.{{28Sn}.{3. 32}}.3, BZn18-18, BZn15-20, CuBe2, thiab lwm yam.
Ua ntej tshaj tawm cov txheej txheem thiab txheej txheem ntawm tooj liab pas nrig, cia peb tham txog dab tsi yog cov txheej txheem kev tsim hlau?
1. Hlau solidification forming yog customarily hu ua casting. Casting yog txheej txheem uas molten hlau yog poured, txhaj los yog nqus mus rau hauv lub pwm kab noj hniav, thiab ces solidified kom tau ib tug casting nrog ib tug tej yam zoo thiab kev ua tau zoo.
2. Kev tsim cov yas hlau yog ib txoj hauv kev uas siv cov yas deformation muaj peev xwm ntawm cov ntaub ntawv hlau los tsim cov yas deformation ntawm cov ntaub ntawv hlau nyob rau hauv 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. 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 forgeability feem ntau ntsuas los ntawm ob qhov ntsuas: plasticity thiab deformation tsis kam ntawm hlau. Yog hais tias lub plasticity siab thiab deformation kuj yog siab, lub forgeability yog zoo; ntawm qhov tsis sib xws, forgeability yog pluag.
3. Hlau vuam txheej txheem. Vuam yog ib txoj kev tsim uas siv cov cua sov los yog siab, los yog ob qho tib si, nrog los yog tsis muaj cov ntaub ntawv muab tub lim, kom ua tiav atomic bonding ntawm cov ntaub ntawv hlau. 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, kos duab, thiab lwm yam.
Copper pas nrig txoj kev? Muaj peb txoj kev tsim cov pas nrig tooj liab, raws li hauv qab no:
1. Nias-(rolling)-drawing-(annealing)-tiav-ua tiav cov khoom.
2. Nruam casting (sab saum toj casting, kab rov tav los yog log hom, crawler hom, dipping) - (rolling) - kos duab - (annealing) - xov - khoom tiav
3. Nruam extrusion-stretching-(annealing)-cov khoom tiav-cov khoom tiav.
2. 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: yog hais txog tus cwj pwm extrusion nyob rau hauv uas extrusion kev taw qhia ntawm cov khoom yog tib yam li cov kev taw qhia ntawm extrusion quab yuam.
(2) Rov qab extrusion: cov kev taw qhia extrusion 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 txhim kho lub neej ntawm cov cuab yeej. Nws yog dav siv nyob rau hauv me me thiab nruab nrab-qhov loj me extruded khoom.
