Kuv tau ua hauj lwm los ntawm kev rov qab los ntawm cov teeb meem nyeem ntawv - Kuv tseem muaj ob peb kab los sau ua ntej kuv rov qab tau dua.Yog tias koj xa ib lo lus nug rau kuv thiab kuv tsis teb nws, thov tos, koj cov lus nug yuav nyob tom ntej.Nrog rau qhov ntawd, cia peb teb cov lus nug.
Q: Peb tab tom sim xaiv cov cuab yeej uas yuav muab 0.09 nti.lub vojvoog.Kuv muab pov tseg ib pawg rau kev sim;kuv lub hom phiaj yog siv tib lub thwj rau tag nrho peb cov ntaub ntawv.Koj puas tuaj yeem qhia kuv siv 0.09 ″ los kwv yees khoov vojvoog?ncig ncig?
A: Yog tias koj yog huab cua tsim, koj tuaj yeem kwv yees lub vojvoog khoov los ntawm kev muab qhov qhib tuag los ntawm feem pua ​​​​ntawm cov khoom siv.Txhua hom khoom muaj qhov feem pua.
Txhawm rau nrhiav feem pua ​​​​ntawm lwm cov ntaub ntawv, koj tuaj yeem sib piv lawv lub zog tensile rau 60,000 psi tensile lub zog ntawm peb cov khoom siv (tsawg carbon txias dov steel).Piv txwv li, yog tias koj cov khoom tshiab muaj lub zog tensile ntawm 120,000 psi, koj tuaj yeem kwv yees tias qhov feem pua ​​​​yuav yog ob zaug ntawm lub hauv paus, lossis txog 32%.
Cia peb pib nrog peb cov khoom siv, qis carbon txias dov hlau nrog lub zog tensile ntawm 60,000 psi.Sab hauv huab cua tsim lub vojvoog ntawm cov khoom siv no yog nruab nrab ntawm 15% thiab 17% ntawm qhov qhib tuag, yog li peb feem ntau pib nrog tus nqi ua haujlwm ntawm 16%.Qhov ntau yam no yog vim lawv qhov sib txawv ntawm cov khoom, thickness, hardness, tensile zog, thiab yield zog.Tag nrho cov khoom siv no muaj ntau qhov kev zam, yog li nws tsis tuaj yeem nrhiav qhov feem pua.Tsis muaj ob daim ntawm cov khoom zoo ib yam.
Nrog rau tag nrho cov no nyob rau hauv lub siab, koj pib nrog ib tug nruab nrab ntawm 16% los yog 0.16 thiab muab nws los ntawm lub thickness ntawm cov khoom.Yog li, yog tias koj tab tom tsim A36 cov khoom loj dua 0.551 nti.Nrog rau qhov tuag qhib, koj sab hauv lub vojvoog khoov yuav tsum yog kwv yees li 0.088 "(0.551 × 0.16 = 0.088).Tom qab ntawd koj yuav siv 0.088 raws li tus nqi xav tau rau sab hauv khoov vojvoog uas koj siv rau hauv khoov nyiaj thiab khoov cov lej rho tawm.
Yog tias koj ib txwm tau txais cov khoom siv los ntawm tib tus neeg muag khoom, koj yuav tuaj yeem pom qhov feem pua ​​​​uas tuaj yeem ua rau koj los ze zog rau sab hauv khoov vojvoog uas koj tau txais.Yog tias koj cov khoom siv los ntawm ntau tus neeg muag khoom sib txawv, nws yog qhov zoo tshaj kom tawm ntawm cov nqi nruab nrab, vim cov khoom siv tuaj yeem sib txawv heev.
Yog tias koj xav nrhiav ib lub qhov tuag uas yuav muab ib qho tshwj xeeb hauv lub vojvoog khoov, koj tuaj yeem hloov cov qauv:
Ntawm no koj tuaj yeem xaiv qhov ze tshaj plaws muaj qhov tuag.Nco ntsoov tias qhov no xav tias lub vojvoog sab hauv ntawm qhov khoov koj xav kom ua tiav qhov sib tw ntawm cov khoom uas koj tab tom airforming.Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws, sim xaiv qhov qhib qhov tuag uas muaj sab hauv khoov vojvoog uas nyob ze lossis sib npaug ntawm cov khoom tuab.
Thaum koj coj tag nrho cov teeb meem no rau hauv tus account, qhov tuag qhov koj xaiv yuav muab rau koj nyob rau hauv lub vojvoog.Kuj xyuas kom meej tias lub punch vojvoog tsis tshaj qhov khoov vojvoog ntawm cov huab cua hauv cov khoom.
Nco ntsoov tias tsis muaj txoj hauv kev zoo tshaj plaws los kwv yees sab hauv khoov radii muab tag nrho cov khoom sib txawv.Siv cov nti dav feem pua ​​​​yog txoj cai ntau dua ntawm tus ntiv tes xoo.Txawm li cas los xij, nws yuav tsim nyog los pauv cov lus nrog tus nqi feem pua.
Q: Tsis ntev los no kuv tau txais ntau cov lus nug txog qhov ua tau ntawm magnetizing cov cuab yeej khoov.Thaum peb tsis tau pom qhov no tshwm sim nrog peb lub cuab yeej, kuv xav paub txog qhov teeb meem.Kuv pom tias yog cov pwm yog magnetized heev, qhov dawb paug tuaj yeem "lo" rau cov pwm thiab tsis tuaj yeem tsim los ntawm ib thooj mus rau lwm qhov.Tsis tas li ntawd, puas muaj lwm yam kev txhawj xeeb?
Teb: Cov brackets lossis brackets uas txhawb kev tuag los yog cuam tshuam nrog cov xovxwm nres lub hauv paus tsis nquag magnetized.Qhov no tsis tau txhais hais tias lub hauv ncoo zoo nkauj tsis tuaj yeem sib nqus.Qhov no tsis zoo li yuav tshwm sim.
Txawm li cas los xij, muaj ntau txhiab daim hlau me me uas tuaj yeem ua cov hlau nplaum, txawm tias nws yog ib daim ntoo hauv cov txheej txheem stamping lossis lub vojvoog ntsuas.Qhov teeb meem no loj npaum li cas?heev tiag.Vim li cas?Yog tias cov khoom me me no tsis raug ntes tau hauv lub sijhawm, nws tuaj yeem khawb rau hauv qhov chaw ua haujlwm ntawm lub txaj, tsim kom muaj qhov chaw tsis muaj zog.Yog hais tias qhov magnetized yog tuab txaus los yog loj txaus, nws tuaj yeem ua rau cov khoom siv hauv txaj tuaj yeem nce ib ncig ntawm cov npoo ntawm qhov ntxig, ua rau lub hauv paus phaj zaum tsis sib npaug lossis sib npaug, uas yuav cuam tshuam rau qhov zoo ntawm cov khoom tsim.
Q: Hauv koj tsab xov xwm Yuav Ua Li Cas Cua Curves Tau Ntse, koj tau hais txog cov qauv: Punch Tonnage = Khau Cheeb Tsam x Khoom Thickness x 25 x Cov Khoom Siv Khoom.Qhov twg 25 los ntawm qhov sib npaug no?
A: Cov qauv no yog muab los ntawm Wilson Tool thiab yog siv los xam cov punch tonnage thiab tsis muaj dab tsi ua nrog kev tsim;Kuv yoog nws los txiav txim siab qhov twg qhov khoov tau nce siab.Tus nqi ntawm 25 nyob rau hauv cov mis yog hais txog lub zog tawm los ntawm cov khoom siv los tsim cov qauv.Los ntawm txoj kev, cov khoom no tsis tau tsim lawm, tab sis nyob ze rau A36 steel.
Tau kawg, ntau ntxiv yog yuav tsum tau ua kom raug xam qhov khoov taw tes thiab khoov kab ntawm lub punch taub.Qhov ntev ntawm qhov khoov, thaj tsam ntawm qhov sib txuas ntawm lub qhov ntswg thiab cov khoom siv, thiab txawm tias qhov dav ntawm qhov tuag ua lub luag haujlwm tseem ceeb.Nyob ntawm qhov xwm txheej, tib lub vojvoog punch rau tib cov khoom tuaj yeem tsim cov khoov ntse thiab khoov zoo meej (piv txwv li, khoov nrog lub vojvoog sab hauv thiab tsis muaj creases ntawm txoj kab quav).Koj yuav pom lub tshuab xam zauv ntse khoov zoo heev ntawm kuv lub vev xaib uas yuav siv tag nrho cov kev hloov pauv no rau hauv tus account.
Lus Nug: Puas muaj ib qho qauv rau rho tawm qhov khoov ntawm lub txee rov qab?Qee lub sij hawm peb cov kws tshaj lij nres siv cov V-qhov me me uas peb tsis suav nrog hauv cov phiaj xwm hauv pem teb.Peb siv tus qauv khoov txiav txiav.
Teb: yog thiab tsis yog.Cia kuv piav.Yog hais tias nws yog dabtsi yog khoov los yog hauv qab stamping, yog hais tias qhov dav ntawm cov pwm sib tw nrog lub thickness ntawm cov khoom molding, lub buckle yuav tsum tsis txhob hloov ntau.
Yog tias koj yog huab cua tsim, sab hauv lub vojvoog ntawm qhov khoov yog txiav txim los ntawm lub qhov ntawm qhov tuag thiab los ntawm qhov ntawd koj coj lub vojvoog uas tau txais hauv qhov tuag thiab xam qhov khoov txiav.Koj tuaj yeem nrhiav tau ntau ntawm kuv cov lus ntawm cov ncauj lus no ntawm TheFabricator.com;nrhiav "Benson" thiab koj yuav pom lawv.
Rau kev ua haujlwm hauv huab cua, koj cov neeg ua haujlwm engineering yuav tsum tau tsim ib lub slab siv khoov rho tawm raws li lub vojvoog ntab uas tsim los ntawm qhov tuag (raws li tau piav qhia hauv "Bend Inside Radius Prediction" thaum pib ntawm tsab xov xwm no).Yog tias koj tus neeg teb xov tooj siv tib lub pwm raws li qhov nws tau tsim los tsim, qhov kawg yuav tsum tsim nyog rau cov nyiaj.
Nov yog qee yam tsis tshua muaj tshwm sim - me ntsis kev cob qhia khawv koob los ntawm cov neeg nyeem avid tawm tswv yim ntawm kab ntawv kuv tau sau rau lub Cuaj Hlis 2021 "Braking Strategies for T6 Aluminium".
Cov lus teb rau cov neeg nyeem: Ua ntej ntawm tag nrho cov, koj tau sau cov lus zoo ntawm cov ntawv hlau ua haujlwm.Kuv ua tsaug rau lawv.Hais txog qhov annealing koj tau piav nyob rau hauv koj lub Cuaj Hlis 2021 kem, kuv xav tias kuv yuav qhia qee qhov kev xav los ntawm kuv qhov kev paub.
Thaum kuv thawj zaug pom qhov ua kom yuam kev ntau xyoo dhau los, kuv tau hais kom siv lub teeb oxy-acetylene, tsuas yog siv cov roj acetylene xwb, thiab pleev xim rau cov kab pwm nrog cov hmoov av dub los ntawm cov roj acetylene hlawv.Txhua yam koj xav tau yog xim av tsaus nti los yog me ntsis dub kab.
Tom qab ntawd tig rau cov pa oxygen thiab ua kom sov cov hlau los ntawm lwm sab ntawm ib sab thiab los ntawm qhov kev ncua deb kom txog rau thaum cov xim hlau uas koj nyuam qhuav txuas tau pib ploj mus thiab ploj tag.Qhov no zoo li yog qhov kub thiab txias rau anneal aluminium txaus los muab 90 degree zoo yam tsis muaj teeb meem tawg.Koj tsis tas yuav ua kom zoo ib feem thaum nws tseem kub.Koj tuaj yeem cia nws txias thiab nws tseem yuav tau annealed.Kuv nco qab ua qhov no ntawm 1/8 "tuab 6061-T6 daim ntawv.
Kuv tau koom nrog hauv kev tsim cov ntawv hlau ua tau zoo rau ntau dua 47 xyoo thiab ib txwm muaj kev sib tw rau camouflage.Tab sis tom qab ntau xyoo, kuv tsis nruab nws ntxiv lawm.Kuv paub tias kuv ua dab tsi!Los yog tej zaum kuv tsuas yog zoo dua ntawm kev zais.Txawm li cas los xij, kuv tuaj yeem tau txais txoj haujlwm ua tiav hauv txoj kev pheej yig tshaj plaws nrog cov frills tsawg.
Kuv paub ib yam los yog ob qho ntawm cov ntawv hlau ntau lawm, tab sis kuv lees txim tias kuv tsis yog tsis quav ntsej.Kuv zoo siab los qhia rau nej paub txog tej kev paub uas kuv tau sau tseg hauv kuv lub neej.
