Kuv tau ua haujlwm los ntawm ntau yam teeb meem ntawm cov nyeem ntawv - kuv tseem muaj ob peb kab ntawv sau ua ntej kuv teb dua. Yog tias koj xa lus nug rau kuv thiab kuv tsis tau teb, thov tos, koj cov lus nug yuav yog qhov tom ntej. Nrog rau qhov ntawd hauv siab, cia peb teb cov lus nug.
Q: Peb tab tom sim xaiv ib lub cuab yeej uas yuav muab 0.09 nti. vojvoog. Kuv pov tseg ntau qhov chaw rau kev sim; kuv lub hom phiaj yog siv tib lub cim rau txhua yam ntawm peb cov ntaub ntawv. Koj puas tuaj yeem qhia kuv yuav ua li cas siv 0.09 ″ los kwv yees qhov nkhaus vojvoog? kev mus ncig vojvoog?
A: Yog tias koj ua cua, koj tuaj yeem kwv yees qhov nkhaus los ntawm kev sib npaug ntawm qhov qhib ntawm lub pwm los ntawm feem pua ​​​​​​raws li hom khoom siv. Txhua hom khoom siv muaj ntau feem pua.
Yuav kom nrhiav tau feem pua ​​rau lwm yam khoom siv, koj tuaj yeem piv lawv lub zog tensile rau 60,000 psi tensile zog ntawm peb cov khoom siv siv (cov hlau uas tsis muaj carbon txias dov). Piv txwv li, yog tias koj cov khoom siv tshiab muaj lub zog tensile ntawm 120,000 psi, koj tuaj yeem kwv yees tias feem pua ​​yuav yog ob npaug ntawm qhov pib, lossis kwv yees li 32%.
Cia peb pib nrog peb cov khoom siv siv, cov hlau uas tsis muaj carbon txias dov nrog lub zog tensile ntawm 60,000 psi. Lub vojvoog tsim cua sab hauv ntawm cov khoom siv no yog nruab nrab ntawm 15% thiab 17% ntawm qhov qhib pwm, 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 siv, tuab, tawv, lub zog tensile, thiab lub zog tawm los. Tag nrho cov khoom siv no muaj ntau yam kev kam rau siab, yog li nws tsis yooj yim sua kom nrhiav tau feem pua ​​tseeb. Tsis muaj ob daim khoom siv zoo ib yam.
Nrog rau txhua yam no hauv siab, koj pib nrog qhov nruab nrab ntawm 16% lossis 0.16 thiab muab qhov ntawd los ntawm qhov tuab ntawm cov khoom siv. Yog li ntawd, yog tias koj tab tom tsim cov khoom siv A36 loj dua 0.551 nti. Nrog lub pwm qhib, koj lub vojvoog khoov sab hauv yuav tsum yog kwv yees li 0.088 ″ (0.551 × 0.16 = 0.088). Tom qab ntawd koj yuav siv 0.088 ua tus nqi xav tau rau lub vojvoog khoov sab hauv uas koj siv hauv kev tso cai khoov thiab kev suav rho tawm khoov.
Yog tias koj ib txwm tau txais cov khoom siv los ntawm tib tus neeg muag khoom, koj yuav pom tau ib feem pua ​​​​​​uas tuaj yeem coj koj mus ze rau sab hauv lub 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 plaws kom tawm hauv tus nqi nruab nrab uas tau xam, vim tias cov khoom siv tuaj yeem sib txawv heev.
Yog tias koj xav nrhiav ib lub qhov tuag uas yuav muab ib lub vojvoog sab hauv, koj tuaj yeem tig cov mis:
Los ntawm no koj tuaj yeem xaiv qhov chaw ze tshaj plaws uas muaj. Nco ntsoov tias qhov no xav tias lub vojvoog sab hauv ntawm qhov khoov uas koj xav ua tiav phim qhov tuab ntawm cov khoom koj tab tom ua cua. Rau qhov zoo tshaj plaws, sim xaiv qhov qhib pwm uas muaj lub vojvoog sab hauv uas nyob ze lossis sib npaug rau qhov tuab ntawm cov khoom.
Thaum koj coj tag nrho cov yam no los xav, lub qhov tuag uas koj xaiv yuav muab rau koj lub vojvoog sab hauv. Tsis tas li ntawd, xyuas kom meej tias lub vojvoog ntawm qhov xuas nrig tsis tshaj qhov nkhaus ntawm huab cua hauv cov khoom.
Nco ntsoov tias tsis muaj txoj hauv kev zoo tshaj plaws los kwv yees qhov nkhaus sab hauv uas muab txhua yam khoom siv hloov pauv. Siv cov feem pua ​​​​​​ntawm qhov dav ntawm cov chips no yog txoj cai tseeb dua. Txawm li cas los xij, nws yuav tsum tau sib 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 kev sib nqus lub cuab yeej khoov. Txawm hais tias peb tsis tau pom qhov no tshwm sim nrog peb lub cuab yeej, kuv xav paub txog qhov loj ntawm qhov teeb meem. Kuv pom tias yog tias lub pwm muaj hlau nplaum ntau, qhov khoob tuaj yeem "lo" rau lub pwm thiab tsis tsim tas li ntawm ib daim mus rau lwm qhov. Dhau li ntawm qhov ntawd, puas muaj lwm yam kev txhawj xeeb?
Lus Teb: Cov brackets lossis brackets uas txhawb nqa lub pwm lossis cuam tshuam nrog lub hauv paus nres nias feem ntau tsis raug magnetized. Qhov no tsis tau txhais hais tias lub hauv ncoo kho kom zoo nkauj tsis tuaj yeem raug magnetized. Qhov no yuav tsis tshwm sim.
Txawm li cas los xij, muaj ntau txhiab daim hlau me me uas tuaj yeem ua rau muaj hlau nplaum, txawm tias nws yog ib daim ntoo hauv cov txheej txheem stamping lossis lub ntsuas radius. Qhov teeb meem no loj npaum li cas? tiag tiag. Vim li cas? Yog tias daim me me ntawm cov khoom no tsis raug ntes raws sijhawm, nws tuaj yeem khawb rau hauv qhov chaw ua haujlwm ntawm lub txaj, tsim kom muaj qhov chaw tsis muaj zog. Yog tias qhov chaw magnetized tuab txaus lossis loj txaus, nws tuaj yeem ua rau cov khoom siv txaj nce siab nyob ib puag ncig ntug ntawm qhov ntxig, ua rau lub phaj hauv paus zaum tsis sib npaug lossis sib npaug, uas yuav cuam tshuam rau qhov zoo ntawm qhov khoom tsim tawm.
Q: Hauv koj tsab xov xwm Yuav Ua Li Cas Cov Kab Ntsig Cua Tau Txais Ntse, koj tau hais txog cov mis: Punch Tonnage = Khau Cheeb Tsam x Khoom Siv Thickness x 25 x Khoom Siv. 25 los qhov twg hauv kab zauv no?
A: Cov mis no yog coj los ntawm Wilson Tool thiab siv los xam qhov punch tonnage thiab tsis muaj dab tsi ua rau kev tsim; Kuv tau hloov kho nws los txiav txim siab qhov twg qhov khoov tau ntxhab dua. Tus nqi ntawm 25 hauv cov mis yog hais txog lub zog tso zis ntawm cov khoom siv siv hauv kev tsim cov mis. Los ntawm txoj kev, cov khoom siv no tsis tau tsim tawm lawm, tab sis ze rau A36 hlau.
Tau kawg, ntau yam ntxiv yuav tsum tau xam kom raug qhov taw tes khoov thiab kab khoov ntawm lub taub hau punch. Qhov ntev ntawm qhov khoov, thaj chaw sib txuas ntawm lub qhov ntswg punch thiab cov khoom siv, thiab txawm tias qhov dav ntawm lub pwm ua lub luag haujlwm tseem ceeb. Nyob ntawm qhov xwm txheej, tib lub vojvoog punch rau tib cov khoom siv tuaj yeem tsim cov khoov ntse thiab cov khoov zoo meej (piv txwv li, khoov nrog lub vojvoog sab hauv uas kwv yees tau thiab tsis muaj qhov nkhaus ntawm kab quav). Koj yuav pom lub tshuab xam zauv khoov ntse zoo heev ntawm kuv lub vev xaib uas coj tag nrho cov hloov pauv no rau hauv tus account.
Lo lus nug: Puas muaj ib daim qauv rau kev rho tawm qhov khoov ntawm lub txee rov qab? Qee zaum peb cov kws kho tshuab nias nres siv cov qhov V me me uas peb tsis tau suav nrog hauv daim phiaj pem teb. Peb siv cov qauv khoov txiav tawm.
Lus teb: yog thiab tsis yog. Cia kuv piav qhia. Yog tias nws yog khoov lossis stamping hauv qab, yog tias qhov dav ntawm pwm phim qhov tuab ntawm cov khoom siv molding, lub buckle yuav tsum tsis txhob hloov ntau.
Yog tias koj tab tom tsim cua, lub vojvoog sab hauv ntawm qhov khoov yog txiav txim siab los ntawm lub qhov ntawm lub pwm thiab los ntawm qhov ntawd koj coj lub vojvoog tau txais hauv lub pwm thiab xam qhov khoov rho tawm. Koj tuaj yeem nrhiav tau ntau yam ntawm kuv cov ntawv sau txog qhov kev kawm no ntawm TheFabricator.com; nrhiav "Benson" thiab koj yuav pom lawv.
Yuav kom cua tshuab ua haujlwm tau, koj cov neeg ua haujlwm engineering yuav tsum tsim ib daim slab siv kev rho tawm khoov raws li lub vojvoog ntab uas tsim los ntawm lub pwm (raws li tau piav qhia hauv "Kev Kwv Yees Sab Hauv Radius" thaum pib ntawm tsab xov xwm no). Yog tias koj tus neeg teb xov tooj siv tib lub pwm li qhov nws tau tsim los ua, qhov kawg yuav tsum tsim nyog cov nyiaj.
Nov yog qee yam uas tsis tshua muaj - kev ua khawv koob me ntsis los ntawm tus nyeem ntawv nyiam tawm tswv yim rau kab lus uas kuv tau sau thaum lub Cuaj Hli 2021 "Cov Tswv Yim Nres rau T6 Aluminium".
Cov lus teb ntawm tus nyeem ntawv: Ua ntej tshaj plaws, koj tau sau cov ntawv zoo heev txog kev ua haujlwm hlau. Kuv ua tsaug rau koj rau lawv. Hais txog qhov annealing uas koj tau piav qhia hauv koj kab lus Cuaj Hlis 2021, kuv xav tias kuv yuav qhia qee qhov kev xav los ntawm kuv qhov kev paub dhau los.
Thaum kuv thawj zaug pom qhov kev ua kom sov ntau xyoo dhau los, lawv hais kom kuv siv lub teeb oxy-acetylene, tsuas yog hlawv cov roj acetylene xwb, thiab pleev cov kab pwm nrog cov pa dub los ntawm cov roj acetylene uas hlawv. Txhua yam koj xav tau yog ib txoj kab xim av tsaus heev lossis me ntsis dub.
Tom qab ntawd tig rau lub oxygen thiab cua sov lub hlau los ntawm sab tod ntawm qhov thiab los ntawm qhov deb tsim nyog kom txog thaum lub hlau xim koj nyuam qhuav txuas pib ploj mus thiab tom qab ntawd ploj mus tag. Qhov no zoo li yog qhov kub zoo rau anneal lub txhuas txaus kom muab 90 degree duab yam tsis muaj teeb meem tawg. Koj tsis tas yuav ua kom lub qhov thaum nws tseem kub. Koj tuaj yeem cia nws txias thiab nws tseem yuav raug annealed. Kuv nco qab ua qhov no ntawm 1/8 ″ tuab 6061-T6 daim ntawv.
Kuv tau koom nrog kev tsim cov hlau ua haujlwm tau ntau tshaj 47 xyoo thiab yeej ib txwm muaj kev txawj ntse rau kev zais. Tab sis tom qab ntau xyoo, kuv tsis teeb tsa nws lawm. Kuv paub tias kuv ua dab tsi! Los yog tej zaum kuv tsuas yog zais zoo dua. Txawm li cas los xij, kuv tau ua tiav txoj haujlwm hauv txoj kev pheej yig tshaj plaws nrog tsawg kawg nkaus frills.
Kuv paub ib lossis ob yam txog kev tsim cov hlau ntawv, tab sis kuv lees tias kuv tsis yog neeg paub dab tsi li. Kuv zoo siab uas tau qhia rau nej txog kev paub uas kuv tau khaws cia hauv kuv lub neej.
