Cov ntsia hlau rub tawm yog dab tsi?
Txheem
Ib qho ntawm cov kev cai tseem ceeb rau cov khoom siv rau kev tsim cov ntsia hlau rub yog lawv lub zog thiab ua haujlwm ntev. Qhov no yog vim tias lub cuab yeej raug cuam tshuam ntau heev thaum nws los rau hauv qhov chaw hla lub taub hau ntawm tus ntsia thawv, thiab tseem yuav tsum muaj lub zog los thawb tus ntsia thawv tawm.
Feem ntau cov ntsia hlau rub yog ua los ntawm cov hlau nplaum, hlau lossis hlau alloy. Cov no yog tag nrho cov alloys ntawm hlau thiab carbon thiab cov ntaub ntawv paub txog lawv lub zog.
Cov ntsia hlau rub cov khoom yuav tsum tau pleev xim rau, lacquered, coated, los yog kho kom tsis txhob hnav thiab corrosion ntawm lub cuab yeej, vim hlau thiab hlau yog qhov cuam tshuam rau corrosion.Tig lub puab tsaig
Lub puab tsaig feem ntau yog ua los ntawm cov hlau los yog hlau. Hlau feem ntau muaj zog dua hlau, tab sis me ntsis nkig. . Nyob rau hauv cov ntaub ntawv ntawm ib tug ntsia thawv puller, qhov no yuav pab kom ntse lub puab tsaig kom lawv tuaj yeem tom rau hauv ntoo thiab tshem tawm cov ntsia hlau zoo.
Koj tseem yuav pom tias, raws li txoj cai, cov sponges raug kho kom sov kom ntxiv dag zog rau cov khoom. Kev kho cua sov muab cov sponges lub zog uas lawv xav tau los nkag rau hauv ntoo thiab lub zog uas lawv xav tau los tuav nruj.pivot point
Lub pivot lossis fulcrum yog ib feem ntawm lub puab tsaig, yog li nws yuav ua los ntawm cov khoom siv tib yam li lub puab tsaig, feem ntau yog hlau lossis hlau.zawv zawg kov
Yog hais tias tus ntsia thawv puller muaj ib tug txav los yog zawv zawg kov, nws ua hauj lwm zoo li ib tug built-in rauj, feem ntau hu ua ib tug rauj los yog rammer. Cov kov feem ntau yog ua los ntawm cov hlau los yog cov hlau nplaum, uas muaj zog thiab nruj.cuam tshuam cheeb tsam
Handleless ntsia thawv pullers muaj lub zog tiaj tus kawg. Lawv feem ntau yog tsim los ntawm cov hlau tawv tawv kom lawv tuaj yeem tiv taus rauj tshuab thiab feem ntau muaj kev tiv thaiv corrosion.
Qhov chaw cuam tshuam no yuav muaj ob daim uas siv tau rauj. Lawv yuav yog forged rau ntawm ib feem ntawm lub square, los yog lawv yuav steel pins.Dab tsi yog qhov txawv ntawm ductile hlau thiab hlau?
cam khwb cia hlau thiab hlau yog hlau alloys, uas yog hlau tov nrog carbon thiab tej zaum lwm yam tshuaj xws li sulfur los yog manganese. Cov tshuaj sib txawv tseem ceeb yog cov hlau tsis tuaj yeem muaj li ntawm 2.0-2.9% carbon, thaum cov hlau yuav muaj cov ntsiab lus carbon tsawg dua 2.1%. Qhov siab dua cov ntsiab lus carbon, cov khoom muaj zog dua, tab sis kuj yog qhov nkig.
Ob leeg hlau thiab hlau feem ntau yog siv rau cov cuab yeej tes. Nyob ntawm daim ntawv thov thiab qhov zoo ntawm cov cuab yeej, cov qib sib txawv ntawm cov alloys no yuav raug siv. Cov cuab yeej siv qib siab alloys yuav raug nqi ntau dua. Ob leeg muaj qhov zoo thiab qhov tsis zoo, yog li qhov twg zoo dua yuav nyob ntawm nws daim ntawv thov thiab cov peev nyiaj ntawm tus neeg siv.
Malleable cam khwb cia hlau
Nws muaj lub zog siab, kub ua hauj, toughness, thiab kuj muaj qee qhov ductility, yog li nws tuaj yeem molded yooj yim heev yam tsis muaj kev tawg. Qhov no ua rau nws siv dav dua li lwm hom hlau thiab txhais tau tias qee zaum siv rau qhov chaw ntawm cov hlau.
Cov hlau nplaum muaj qhov txwv ntawm qhov loj ntawm qhov nws tuaj yeem tsim tau, yog li nws feem ntau yog siv rau cov khoom me me uas yuav tsum tau muaj zog tab sis muaj qee qhov yooj, xws li nrog cov cuab yeej tes, cov khoom siv hluav taws xob, thiab cov khoom siv tshuab. Koj yuav pom tias cov tes tuav ntawm qee tus ntsia thawv rub tawm yog ua los ntawm cov hlau tsis muaj hlau, vim cov no yog cov nyias nyias uas yuav tsum muaj zog thiab muaj qhov yooj yim me ntsis thaum lub puab tsaig ntaus ntoo.
Cov hlau nplaum muaj cov yam ntxwv zoo dua li cov cam khwb cia hlau, yog li koj tuaj yeem pom tias tus kov yuav yog cam khwb cia hlau tab sis lub puab tsaig yuav yog cov hlau forged. Forging qhov chaw muab ntau precision dua casting.
Cov txheej txheem ntawm cov hlau tsis muaj hlau yog qhov nyuaj heev, yog li kev tsim khoom kim dua li kev tsim cov hlau grey zoo tib yam lossis cam khwb cia hlau.
Hlau
Niaj hnub no, steel feem ntau yog qhov kev xaiv nrov dua rau cov cuab yeej, txawm hais tias koj yuav pom qhov sib txawv ntawm cov hlau siv. Feem ntau, ntsia thawv rub qhov chaw yog tsim los ntawm cov hlau los yog cov hlau tawv tawv vim lawv muaj zog, tawv, thiab ntau yam.
Txawm li cas los xij, piv rau cov hlau nplaum, cam khwb cia hlau tsis tshua muaj hnav tsis kam thiab ductility thiab tsis tuaj yeem tsim nyob rau hauv cov txheej txheem casting kom raug raws li cov hlau ductile. - forging tau dhau los ua kim dua nws cov casting.
hlau alloy
Alloy steel hais txog cov hlau uas tseem muaj cov pa roj carbon thiab lwm yam khoom sib txawv. Qhov no yuav hloov nws cov khoom siv kho tshuab, qhov kev hloov pauv no yuav raug tswj kom paub tseeb tias nws tsim nyog rau nws lub hom phiaj tshwj xeeb.
Rau cov ntsia hlau, cov hlau yuav tsum muaj zog thiab tawv nrog me ntsis ntawm kev yooj yim kom nws tuaj yeem tiv taus lub zog ntawm lub tshuab rau ntoo.
Txij li cov tshuaj muaj pes tsawg leeg ntawm cov hlau tuaj yeem tswj tau thiab hloov kho rau lub hom phiaj sib txawv, nws muaj qhov sib txawv thiab hloov tau yooj yim rau cov qauv sib txawv. Qhov me me thiab loj qhov hnyav txog li ntau pua tons tuaj yeem raug pov los ntawm cov hlau.
Hardened hlau
Hardened steel feem ntau yog hais txog siab lossis nruab nrab carbon steel uas tau tshwj xeeb hardened. Qhov siab dua cov ntsiab lus ntawm cov hlau, qhov nyuaj thiab muaj zog nws ua, txawm li cas los xij, qhov no txo nws lub peev xwm deform yooj yim thiab ua rau nws nkig. Lub puab tsaig ntawm cov ntsia hlau rub feem ntau yog ua los ntawm cov hlau tawv tawv, yog li lawv muaj zog txaus los txiav ntoo.
Txhawm rau ntxiv dag zog rau cov hlau, nws tuaj yeem raug kho cua sov, txheej txheem uas nws tau muab tso rau hauv qhov kub thiab txias sai sai nrog dej, roj, lossis roj inert. Qhov no yog hu ua tempering thiab tempering.
Qhov twg zoo dua?
Qhov zoo ntawm ntau yam hlau thiab cam khwb cia hlau yog qhov nyuaj rau kev soj ntsuam yooj yim - cov hlau uas muaj cov khoom sib txawv tau txais los ntawm cov hlau sib txawv. Ib qho kev qhia zoo ntawm qhov zoo ntawm cov hlau feem ntau yog lub koob npe nrov ntawm cov khoom lag luam uas ua rau nws thiab tus nqi ntawm cov cuab yeej.
Hlau tuaj yeem ua rau me me thiab yog li cov duab meej dua, muaj zog heev tab sis tuaj yeem nkig, thiab feem ntau yog me ntsis kim dua li cov cuab yeej steel. Wrought steel zoo li yuav pheej yig dua thiab yuav luag zoo li hlau, tab sis yuav tsis tsim cov khoom zoo raws li cov hlau. Alloyed thiab hardened steels yuav tau txais lub zog ntau dua li cov qauv hlau, ua rau lawv muaj zog dua hlau, tab sis lawv yuav nkig thiab kim dua.
