Dab tsi yog forging

Forging yog ib txoj hauv kev ua cov ntaub ntawv los ntawm cua sov hlau mus rau lub xeev yas thiab siv lub zog los tsim cov khoom. Qhov no tso cai rau cov khoom siv hammered, compressed, los yog ncab rau hauv cov duab uas xav tau. Forging tuaj yeem tshem tawm cov teeb meem xws li casting porosity generated thaum lub sij hawm metallurgical txheej txheem, optimize lub microstructure, thiab vim hais tias tag nrho cov hlau flowline yog khaws cia, cov cuab yeej cuab tam ntawm forgings feem ntau zoo dua rau cov castings ntawm tib cov khoom.

Thaum pib ntawm steel recrystallization kub yog hais txog 727 ℃, tab sis 800 ℃ feem ntau yog siv los ua kab sib faib. Tshaj 800 ℃ yog kub forging; ntawm 300-800 ℃ yog hu ua sov forging lossis semi-kub forging, thiab forging ntawm chav tsev kub yog hu ua txias forging.

Kev tsim khoom ntawm kev nqa khoom feem ntau yog siv kub forging.

Forging txheej txheem

Cov kauj ruam ntau lawm ntawm kub forging bolts yog: txiav → cua sov (kuj hlau cua sov) → forging → xuas nrig ntaus → trimming → tua blasting → threading → galvanizing → xaim tu

Txiav: Txiav lub round bar rau hauv qhov ntev kom tsim nyog

Cua sov: Tshav kub lub voj voog mus rau lub xeev yas los ntawm kev tiv thaiv hlau cua sov

Forging: Hloov cov khoom zoo los ntawm kev quab yuam nyob rau hauv tus ntawm cov pwm

xuas nrig ntaus: Ua lub hollow qhov nyob rau hauv nruab nrab ntawm lub workpiece

Txiav: Tshem tawm cov khoom siv ntau dhau

Tua blasting: Tshem tawm burrs, nce nto tiav, nce roughness, thiab pab galvanizing

Xov: Txheej txheem xov

Galvanizing: Ua kom xeb kuj

Hlau tu: Tom qab galvanizing, tej zaum yuav muaj qee cov zinc slag seem hauv cov xov. Cov txheej txheem no ntxuav cov xov thiab xyuas kom nruj.

Feature ntawm forged qhov chaw

Piv nrog cov castings, hlau ua los ntawm forging tuaj yeem txhim kho nws cov microstructure thiab mechanical zog. Tom qab txoj kev forging kub ua hauj lwm deformation ntawm cov qauv casting, vim qhov deformation thiab recrystallization ntawm cov hlau, thawj coarse dendrite thiab columnar nplej ua nplej uas yog finer thiab sib npaug faib nrog equiaxed recrystallized qauv. Kev cais qub, kev xoob, pores, thiab inclusions nyob rau hauv lub steel ingot yog compacted thiab welded los ntawm siab, thiab lawv cov qauv ua ntau compact, uas txhim kho cov hlau plasticity thiab mechanical zog.

Mechanical zog ntawm castings yog qis dua cov forgings ntawm tib cov khoom. Ntxiv rau, forging ua tuaj yeem ua kom muaj kev sib txuas ntawm cov hlau fiber ntau, yog li ntawd cov qauv fiber ntau ntawm forging yog zoo ib yam nrog forging zoo, thiab cov kab hlau ntws tsis zoo, uas tuaj yeem xyuas kom meej tias cov khoom muaj cov khoom siv kho tshuab zoo thiab lub neej ua haujlwm ntev. Forgings ua los ntawm precision forging, txias extrusion, thiab cov txheej txheem sov extrusion tsis tuaj yeem muab piv nrog cov castings.

Forgings yog cov khoom zoo li los ntawm kev siv lub siab rau cov hlau los ntawm cov yas deformation kom tau raws li qhov yuav tsum tau ua los yog tsim nyog compression quab yuam.. Hom quab yuam no feem ntau ua tiav siv lub rauj hlau lossis lub siab. Cov txheej txheem forging tsim cov qauv zoo nkauj thiab txhim kho lub cev ntawm cov hlau. Hauv kev siv cov khoom siv tiag tiag, ib qho kev tsim kom raug tuaj yeem ua rau cov nplej ntws mus rau qhov kev taw qhia ntawm lub ntsiab siab. Castings yog cov khoom zoo li hlau uas tau txais los ntawm ntau txoj kev casting, nyob rau hauv lwm yam lus, cov smelted kua hlau yog txhaj rau hauv lub pwm npaj los ntawm pouring, txhaj tshuaj, nqus, los yog lwm txoj kev casting, thiab tom qab txias, cov khoom tau txais muaj cov duab zoo, qhov loj, thiab kev ua tau zoo tom qab ntxuav thiab tom qab ua tiav, lwm.

Kev siv cov khoom forged

Forging ntau lawm yog ib qho ntawm cov txheej txheem tseem ceeb uas muab kev ua haujlwm ntxhib ntawm cov khoom siv tshuab hauv kev lag luam kev lag luam.. Los ntawm forging, tsis tsuas yog tuaj yeem tau txais cov duab ntawm cov khoom siv kho tshuab, tab sis cov qauv sab hauv ntawm cov hlau kuj tuaj yeem txhim kho, thiab cov khoom siv kho tshuab thiab lub cev muaj zog ntawm cov hlau tuaj yeem txhim kho. Forging ntau lawm txoj kev yog feem ntau yog siv los tsim ib qho tseem ceeb mechanical qhov chaw uas yuav tsum tau loj zog thiab muaj siab. Piv txwv li, chav turbine generator shafts, rotors, impellers, cov hniav, daim ntaub, loj hydraulic xovxwm kab, lub tog raj kheej siab, dov zeb yob, internal combustion engine cranks, txuas rods, iav, bearings, thiab qhov tseem ceeb hauv kev lag luam tiv thaiv lub teb chaws xws li cov phom loj yog txhua yam tsim los ntawm forging.

Yog li ntawd, forging ntau lawm yog dav siv nyob rau hauv metallurgical, mining, tsheb, tsheb laij teb, tshuab txiav, roj av, tshuaj, kev dav hlau, aerospace, riam phom, thiab lwm yam kev lag luam sectors. Hauv lub neej niaj hnub, forging ntau lawm kuj occupies ib qho tseem ceeb txoj hauj lwm.
