ZogVam khom rau lawv tus kheej qhov ntev thiab cov khoom siv zog kom tiv taus sab nraud thauj khoom, uas yuav tsum muaj cov ntaub ntawv kom muaj lub zog siab, tawv thiab hnav tsis kam; vim yog cov duab nyuaj ntawm lub zog, tusZogYuav tsum muaj qhov ntsuas siab, thiab cov khoom siv tseem xav tau kev tsim khoom zoo. Cov ntaub ntawv siv feem ntau yog forged steel, cam khwb cia hlau, thiab cam khwb cia hlau.
1. Forged steel raws li lub hardness ntawm tus hniav nto, nws tau muab faib ua ob pawg:
Thaum HB <350, nws yog hu ua cov hniav muag muag
Thaum HB> 350, nws yog hu ua cov hniav tawv
1.1. Hniav nto hardness HB <350
Cov txheej txheem: Forging Blanking → Qhov Kev Ua Tsis Zoo - ntxhib tig → quenching thiab tempering, xov
Cov ntaub ntawv kheev siv; 45 #, 35SIMN, 40CR, 40CRNI, 40MNB
Nta: Nws muaj qhov zoo tag nrho kev ua tau zoo, cov hniav sib npaug muaj lub zog siab thiab tawv tawv, thiab tus hniav tus hniav muaj cov khoom muaj zog zoo. Tom qab kev kho cua sov, qhov tseeb ntawmZogKev txiav tuaj yeem ncav cuag 8 qib. Nws yog qhov yooj yim rau kev tsim khoom, kev lag luam, thiab muaj cov khoom lag luam siab. Qhov precision tsis yog siab.
1.2 hniav saum npoo hardness Hb> 350
1.2.1 Thaum siv cov hlau roj carbon steel:
Txheej Txheem: Forging Seem → Roughized → Kev Txiav Txim Siab → Kev Kub Siab Tshaj Plaws → Lawb Dag Thiab Kub Khiav-Hauv, Hluav Taws Xob Khiav-Hauv.
Cov Khoom Siv Uas Siv:45, 40CR, 40cni
Nta: Cov hniav saum npoo hardness yog siab HRC = 48-55, lub zog tiv tauj yog siab, thiab cov coj tsis kam yog qhov zoo. Tus hniav tus hniav tswj hwm kev nruj me ntsis tom qab quenching thiab tempering, muaj kev cuam tshuam zoo thiab muaj peev xwm thauj khoom-coj kev muaj peev xwm. Qhov tseeb yog txo los ntawm ib nrab, nce txog qib 7 qhov tseeb. Haum rau huab hwm coj ntau lawm, xws li nruab nrab ceev thiab nruab nrab-thauj khoom kis tau lub zog rau tsheb, tshuab cov cuab yeej, thiab lwm yam.
1.2.2 Thaum siv cov roj av qis: Forging dawb → Roalching thiab Tempering → Mus txog 6 thiab 7 qib.
Cov ntaub ntawv kheev siv; 20Cr, 20cmbti, 20mnb, 20cmmnto nta: hniav ua kom tawv thiab muaj zog muaj peev xwm muaj peev xwm. Cov tub ntxhais muaj cov khoom zoo thiab cuam tshuam tsis kam. Nws yog tsim nyog rau kev kub ceev, hnyav-thauj khoom, sib kis tau sib kis lossis qee lub sijhawm nrog cov qauv sib txuas, cov zog aviation thiab aviation.
2. Nrug Steel:
Thaum lubtej cuab tamTxoj kab uas hla D> 400mm, cov qauv yog qhov nyuaj, thiab kev lom zem yog qhov nyuaj, Cam Khwb Steel Khoom ZG45.ZG55 tuaj yeem siv rau ib txwm muaj. Qub, quenching thiab tempering.
3. Nro Hlau:
Lub zog tiv taus rau Adhesion thiab pitting corrosion, tab sis tsis zoo tsis kam rau kev cuam tshuam thiab kev puas tsuaj. Nws yog qhov haum rau kev ua haujlwm ruaj khov, lub zog qis, qis nrawm los yog cov duab loj thiab cov duab nyuaj. Nws tuaj yeem ua haujlwm nyob rau hauv cov roj tsis muaj zog thiab haum rau kev kis tau.
4. Nws yog xim hlau cov khoom siv:
Npuag, ntoo, yas, nylon, haum rau kev kub ceev thiab lub teeb ntsaws.
Thaum xaiv cov ntaub ntawv, kev txiav txim siab yuav tsum tau muab rau qhov tseeb tias kev ua haujlwm ntawm cov iav sib txawv, thiab cov khoom tsis ua haujlwm ntawm cov khoom siv ntawm cov iav thiab cov khoom siv xaiv thiab cov pob kub.
1. Thaum lub iav cov hniav tau yooj yim tawg nyob rau hauv kev cuam tshuam kev cuam tshuam, thiab cov roj av qis dua, thiab cov roj av tsis tuaj yeem xaiv rau carburizing thiab quenching.
2. Rau siab-nrawm kaw cov kis tau kaw, yog tias cov ntaub ntawv nrog cov hniav hniav zoo dua yuav tsum tau xaiv, thiab cov pa roj teeb zoo dua tuaj yeem siv tau.
3. Rau qis-nrawm thiab nruab nrab-thauj khoom, thaum cov iav hniav ua kom zoo, thiab muaj cov tshuaj tua kab mob zoo, thiab cov pa roj carbon monoxide, thiab tempered tuaj yeem xaiv tau.
4. Mob siab muaj ntau cov ntaub ntawv me me, kev tswj kom yooj yim, thiab xav txog cov peev txheej thiab muab khoom. 5. Thaum tus qauv loj yog kev cog lus thiab hnav tsis kam yog siab, hlau hlau yuav tsum tau siv. 6. Cov khoom siv thiab thev naus laus zis ntawm cov chaw tsim khoom.
