Xav txog cov chaw tsim khoom nkag mus rau hauv ib daim ntawv cog lus uas muaj qhov tseem ceeb stainless hlau fabrication.Sheet hlau thiab raj ntu yog txiav, khoov thiab welded ua ntej tsaws ntawm qhov chaw ua tiav.Qhov muaj cov phaj welded vertically mus rau lub raj.Cov welds zoo, tab sis nws tsis yog lub zoo meej dime tus neeg muas zaub tab tom nrhiav. Yog li ntawd, lub grinder xiav, peb siv sij hawm ntau dua li cov hlau dissipation. nto - ib qho kev qhia meej ntawm cov khoom siv hluav taws xob ntau dhau. Hauv qhov no, nws txhais tau tias ib feem yuav tsis ua raws li cov neeg siv khoom xav tau.
Feem ntau ua manually, sib tsoo thiab ua tiav yuav tsum tau dexterity thiab kev txawj ntse.Kev ua yuam kev hauv kev ua tiav yuav kim heev, muab tag nrho cov nqi uas tau muab rau cov khoom ua haujlwm.Ntxiv cov khoom siv hluav taws xob kim heev xws li stainless hlau, rework thiab seem installation cov nqi yuav siab dua.Combined nrog cov teeb meem xws li kis kab mob thiab passivation tsis ua hauj lwm, ib zaug lucrative mis-sensitive txoj hauj lwm-los ua ib lub koob npe nrov.
Yuav ua li cas manufacturers tiv thaiv tag nrho cov no?Lawv tuaj yeem pib los ntawm kev txhim kho lawv txoj kev paub txog kev sib tsoo thiab kev ua tiav, nkag siab txog lub luag haujlwm lawv txhua tus ua si thiab lawv cuam tshuam li cas stainless hlau workpieces.
Lawv tsis yog synonyms.Qhov tseeb, txhua leej txhua tus muaj lub hom phiaj sib txawv.Kev sib tsoo tshem tawm cov ntaub ntawv xws li burrs thiab cov hlau ntau dhau, thaum ua tiav muab ib qho tiav ntawm cov hlau nto.Qhov tsis meej pem yog nkag siab, xav tias cov neeg sib tsoo loj sib tsoo log tshem tawm ntau cov hlau sai heev, thiab ua li ntawd tuaj yeem tawm hauv qhov sib sib zog nqus khawb heev.Tab sis hauv kev sib tsoo, khawb tsuas yog ib qho kev sib tsoo;lub hom phiaj yog kom tshem tawm cov khoom siv sai sai, tshwj xeeb tshaj yog thaum ua haujlwm nrog cov hlau tsis zoo xws li stainless hlau.
Kev ua tiav yog ua tiav hauv cov kauj ruam, raws li tus neeg teb xov tooj pib nrog lub pob zeb loj dua thiab nce mus rau kev sib tsoo zoo dua, cov khoom siv tsis yog cov khoom siv, thiab tej zaum muaj cov ntaub thiab polishing muab tshuaj txhuam kom ua tiav daim iav tiav.Lub hom phiaj yog ua kom tiav ib qho kawg tiav (cov qauv kos).Txhua kauj ruam (qhov zoo dua grit) tshem tawm cov khawb ntxaum los ntawm cov kauj ruam dhau los thiab hloov lawv.
Vim tias kev sib tsoo thiab kev ua tiav muaj cov hom phiaj sib txawv, lawv feem ntau tsis ua tiav ib leeg thiab tuaj yeem sib tw sib tw yog tias siv cov khoom siv tsis raug.Kom tshem tawm cov hlau ntau dhau, cov neeg ua haujlwm siv cov log sib tsoo kom sib sib zog nqus khawb, tom qab ntawd muab ib feem rau tus hnav khaub ncaws, uas tam sim no yuav tsum siv sij hawm ntau heev tshem tawm cov khawb sib sib zog nqus.Qhov kev sib tsoo-rau-tiav cov khoom yuav tsum tau ua kom tiav ntau dua. txheej txheem.
Workpiece nto tsim los rau manufacturability feem ntau tsis tas yuav sib tsoo thiab xov.Parts uas yog hauv av tsuas yog ua qhov no vim hais tias kev sib tsoo yog txoj kev ceev tshaj kom tshem tawm welds los yog lwm yam ntaub ntawv thiab cov sib sib zog nqus khawb sab laug los ntawm lub sib tsoo log yog raws nraim li cov neeg siv khoom xav tau.Cov khoom uas tsuas yog yuav tsum tau ua tiav yog tsim nyob rau hauv ib txoj kev uas tsis tas yuav tsum tau ntau tshaj cov khoom tshem tawm.Ib qho piv txwv zoo nkauj yog ib qho zoo nkauj shielded steel hlau. ed mus rau qhov kawg qauv ntawm lub substrate.
Grinders nrog lub log qis qis tuaj yeem nthuav tawm cov teeb meem tseem ceeb thaum ua haujlwm nrog stainless hlau. Ib yam li ntawd, overheating tuaj yeem ua rau bluing thiab hloov cov khoom siv.Lub hom phiaj yog ua kom cov hlau tsis huv kom txias li sai tau thoob plaws hauv cov txheej txheem.
Txog rau qhov kawg no, nws pab xaiv cov kev sib tsoo log nrog kev tshem tawm ceev tshaj plaws rau daim ntawv thov thiab kev siv nyiaj.Zirconia log zom sai dua alumina, tab sis feem ntau, cov log ceramic ua haujlwm zoo tshaj plaws.
Cov tawv tawv heev thiab ntse ceramics hnav nyob rau hauv ib txoj kev tshwj xeeb.Raws li lawv maj mam disintegrate, lawv tsis zom tiaj, tab sis tuav ib tug ntse ntug.Qhov no txhais tau hais tias lawv muaj peev xwm tshem tawm cov ntaub ntawv sai heev, feem ntau nyob rau hauv ib feem ntawm lub sij hawm ntawm lwm yam sib tsoo log.Qhov no feem ntau ua ceramic sib tsoo log tsim nyog rau cov nyiaj.Lawv yog zoo tagnrho rau stainless hlau daim ntaub ntawv vim hais tias lawv tshem tawm cov chips loj sai thiab tsim kom muaj cua sov tsawg thiab distortion.
Tsis muaj teeb meem twg kev sib tsoo log ib lub chaw tsim khoom xaiv, tej zaum yuav tsum tau khaws cia rau hauv siab. Feem ntau cov tuam txhab paub tias lawv tsis tuaj yeem siv tib lub log sib tsoo ntawm cov hlau thiab cov hlau tsis muaj steel.Ntau tus neeg lub cev cais lawv cov pa roj carbon thiab stainless hlau sib tsoo cov haujlwm.Txawm tias cov pa roj carbon hlau me me poob rau ntawm cov hlau tsis muaj steel workpieces tuaj yeem ua rau muaj teeb meem tsis sib haum.Muaj kev lag luam, xws li cov chaw muag tshuaj, kev sib tsoo tsis muaj nuclear. Nyob rau hauv lub log rau stainless hlau yuav luag dawb (tsawg dua 0.1%) ntawm hlau, sulfur thiab chlorine.
Sib tsoo log tsis tuaj yeem zom lawv tus kheej;lawv xav tau lub cuab yeej hluav taws xob.Txhua tus neeg tuaj yeem tout cov txiaj ntsig ntawm kev sib tsoo log lossis cov cuab yeej siv hluav taws xob, tab sis qhov tseeb yog cov cuab yeej siv hluav taws xob thiab lawv cov log sib tsoo ua haujlwm raws li qhov system.Ceramic sib tsoo lub log yog tsim los rau lub kaum sab xis grinders nrog qee tus nqi ntawm lub zog thiab torque.Thaum qee qhov cua grinders muaj qhov tsim nyog tshwj xeeb, feem ntau ceramic log sib tsoo ua tiav nrog cov cuab yeej hluav taws xob.
Grinders nrog lub zog tsis txaus thiab lub zog tuaj yeem ua rau muaj teeb meem loj heev, txawm tias muaj cov abrasives siab tshaj plaws.Qhov tsis muaj lub zog thiab lub zog tuaj yeem ua rau lub cuab yeej ua kom lub zog qeeb qeeb hauv qhov siab, qhov tseem ceeb tiv thaiv cov khoom ceramic ntawm lub log sib tsoo los ntawm kev ua raws li lawv tau tsim los ua: sai sai tshem tawm cov hlau loj, yog li txo cov khoom siv thermal nkag mus rau hauv lub sib tsoo log.
Qhov no ua rau lub voj voog tsis zoo: Cov neeg ua haujlwm sib tsoo pom cov khoom tsis raug tshem tawm, yog li lawv instinctively thawb nyuaj, uas ua rau cov cua sov ntau dhau thiab bluing.Lawv thaum kawg thawb hnyav heev kom lawv glaze lub log, uas ua rau lawv ua hauj lwm nyuaj thiab tsim kom muaj cua sov ntau dua ua ntej lawv paub tias lawv yuav tsum tau hloov lub log.Yog tias koj ua haujlwm li no ntawm cov khoom nyias nyias los yog cov nplooj ntawv ncaj nraim.
Tau kawg, yog tias cov neeg ua haujlwm tsis raug cob qhia zoo, txawm tias cov cuab yeej zoo tshaj plaws, lub voj voog tsis zoo no tuaj yeem tshwm sim, tshwj xeeb tshaj yog thaum nws los txog rau lub siab lawv muab tso rau ntawm qhov chaw ua haujlwm.Qhov kev xyaum zoo tshaj plaws yog kom ze li sai tau rau qhov kev ntsuas tam sim no ntawm lub tshuab grinder.Yog tias tus neeg teb xov tooj siv 10 amp grinder, lawv yuav tsum nias nyuaj kom lub grinder rub txog 10 amps.
Kev siv lub ammeter tuaj yeem pab ua qauv kev sib tsoo yog tias cov chaw tsim khoom ua haujlwm ntau ntawm cov khoom kim heev stainless hlau. Tau kawg, ob peb txoj haujlwm yeej siv lub ammeter tsis tu ncua, yog li koj tus thawj koom ruam zoo tshaj plaws yog mloog kom zoo.Yog tias tus neeg teb xov tooj hnov ​​​​thiab hnov ​​​​lub RPM poob sai, lawv yuav raug thawb heev.
Kev mloog cov lus kov uas lub teeb dhau (xws li lub siab me me) tuaj yeem nyuaj, yog li qhov no, ua tib zoo mloog rau cov pa taws tuaj yeem pab tau. Sib tsoo stainless hlau yuav tsim cov nplaim taws tsaus dua li cov pa roj carbon steel, tab sis lawv yuav tsum tseem pom thiab tawm ntawm qhov chaw ua haujlwm zoo ib yam.Yog tias tus neeg teb xov tooj dheev pom cov nplaim taws tsawg dua, nws yuav yog vim lawv tsis siv lub siab txaus lossis glazing lub log.
Cov neeg ua haujlwm kuj yuav tsum muaj lub kaum ntse ntse ua haujlwm zoo ib yam.Yog tias lawv mus txog qhov chaw ua haujlwm ntawm lub kaum sab xis ze (ze li sib npaug rau qhov chaw ua haujlwm), lawv tuaj yeem ua rau muaj cua sov ntau;Yog tias lawv mus rau ntawm lub kaum sab xis siab dhau (ze li ntsug), lawv pheej hmoo khawb lub npoo ntawm lub log rau hauv cov hlau.Yog tias lawv siv lub log hom 27, lawv yuav tsum ua haujlwm ntawm lub kaum sab xis ntawm 20 txog 30 degrees.Yog tias lawv muaj hom 29 log, lawv lub kaum sab xis ua haujlwm yuav tsum nyob ib ncig ntawm 10 degrees.
Hom 28 (tapered) sib tsoo lub log feem ntau yog siv rau kev sib tsoo ntawm qhov chaw tiaj tus kom tshem tawm cov khoom ntawm txoj kev sib tsoo dav dua.Cov log tapered no kuj ua haujlwm zoo tshaj plaws ntawm kev sib tsoo kaum sab xis (kwv yees li 5 degrees), yog li lawv pab txo cov neeg ua haujlwm qaug zog.
Qhov no qhia txog lwm qhov tseem ceeb: xaiv qhov zoo ntawm kev sib tsoo log.Cov hom 27 lub log muaj qhov sib cuag ntawm cov hlau nto;Hom 28 log muaj cov kab sib txuas vim nws cov duab conical;Hom 29 log muaj qhov sib cuag.
Txog tam sim no feem ntau hom 27 lub log tuaj yeem tau txais txoj haujlwm ua tiav hauv ntau daim ntawv thov, tab sis lawv cov duab ua rau nws nyuaj rau kev tswj cov khoom sib sib zog nqus thiab cov nkhaus, xws li cov khoom sib txuas ntawm cov hlau tsis muaj steel hlau. Cov duab profile ntawm Hom 29 log ua rau nws yooj yim dua rau cov neeg tsav tsheb uas yuav tsum tau sib tsoo ua ke ntawm nkhaus thiab tiaj tus. Hom 29 lub log ua qhov no los ntawm kev nce qhov chaw sib cuag ntawm qhov chaw, uas txhais tau hais tias tus neeg teb xov tooj zoo dua rau qhov chaw sib tsoo. nce.
Qhov tseeb, qhov no siv tau rau txhua lub log sib tsoo.Thaum sib tsoo, tus neeg teb xov tooj yuav tsum tsis txhob nyob hauv tib qhov chaw ntev ntev.Suppose tus neeg teb xov tooj tshem tawm cov hlau los ntawm cov fillet ob peb taw ntev.Nws tuaj yeem steer lub log nyob rau hauv luv luv thiab down motions, tab sis ua li ntawd yuav overheat lub workpiece vim hais tias nws khaws lub log nyob rau hauv ib tug me me cheeb tsam rau lub sij hawm ntev ntawm lub sij hawm.Lavxias teb sab tus neeg teb xov tooj nyob rau hauv ib lub sij hawm ntev. muab lub sijhawm ua haujlwm kom txias) thiab hla lub workpiece nyob rau tib qho kev taw qhia ze ntawm tus ntiv taw.Lwm cov txheej txheem ua haujlwm, tab sis lawv txhua tus muaj ib qho zoo sib xws: lawv tsis txhob overheating los ntawm kev ua kom lub log sib tsoo txav.
Feem ntau siv "carding" cov tswv yim kuj pab kom ua tiav qhov no.Suppose tus neeg teb xov tooj yog sib tsoo lub pob tw weld nyob rau hauv ib qho chaw tiaj tus. Kom txo tau thermal stress thiab over-digging, nws tsis txhob thawb lub grinder raws li kev sib koom ua ke. Xwb, nws pib thaum kawg thiab rub lub grinder raws li kev sib koom ua ke.Qhov no kuj tiv thaiv lub log los ntawm kev khawb ntau dhau rau hauv cov khoom.
Tau kawg, txhua yam txheej txheem tuaj yeem overheat cov hlau yog tias tus neeg teb xov tooj mus qeeb heev.Muaj qeeb heev thiab tus neeg teb xov tooj yuav overheat lub workpiece;mus nrawm heev thiab kev sib tsoo yuav siv sij hawm ntev.Nrhiav qhov feedrate qab zib qhov chaw feem ntau yuav tsum tau muaj kev paub.Tab sis yog hais tias tus neeg teb xov tooj tsis paub txog txoj hauj lwm, lawv tuaj yeem zom cov seem kom tau "xav" ntawm tus nqi pub rau lub workpiece ntawm tes.
Lub tswv yim ua tiav yog nyob ib ncig ntawm qhov chaw saum npoo ntawm cov khoom thaum nws tuaj txog thiab tawm mus rau qhov chaw ua tiav.Ntawm qhov chaw pib (qhov chaw tau txais) thiab qhov kawg taw tes (kom tiav), ces ua ib txoj kev npaj los nrhiav txoj hauv kev zoo tshaj plaws ntawm ob lub ntsiab lus.
Feem ntau txoj hauv kev zoo tshaj plaws tsis pib nrog kev txhoj puab heev abrasive.Qhov no tej zaum yuav zoo li counterintuitive.Tom qab tag nrho, vim li cas ho tsis pib nrog coarse xuab zeb kom tau ib tug ntxhib nto thiab ces txav mus rau finer xuab zeb?Nws puas yuav tsis zoo heev pib nrog ib tug finer grit?
Tsis tas li, qhov no dua yuav tsum tau ua nrog qhov xwm txheej ntawm kev sib tsoo.Raws li txhua kauj ruam mus txog qhov me me, lub tshuab txias hloov cov khawb ntxaum nrog qhov tob dua, cov khawb zoo dua.Yog tias lawv pib nrog 40-grit sandpaper lossis flip disk, lawv yuav tawm hauv cov khawb tob rau ntawm cov hlau.Yog vim li cas cov 40 grit tiav cov khoom siv muaj nyob.Txawm li cas los xij, yog tias tus neeg siv khoom thov qhov No. 4 tag (directional brushed finish), sib sib zog nqus khawb tsim los ntawm No. 40 abrasive yuav siv sij hawm ntev los tshem tawm. Cov khaub ncaws los ntawm ntau qhov ntau thiab tsawg grit, los yog siv sij hawm ntev siv nplua-grained abrasives kom tshem tawm cov khawb me me xwb, tab sis tsis muaj ntau qhov kev qhia. lub workpiece.
Tau kawg, siv cov nplua grit abrasives rau ntawm qhov chaw ntxhib tuaj yeem ua rau qeeb thiab ua ke nrog cov txheej txheem tsis zoo, qhia cov cua sov ntau dhau.Qhov no yog qhov uas ob-hauv-ib lossis staggered nrov plig plawg disc tuaj yeem pab tau.Cov discs no suav nrog cov ntaub abrasive ua ke nrog cov ntaub ntawv kho deg.Lawv zoo tso cai rau tus neeg hnav khaub ncaws siv cov khoom siv abrasives kom tshem tawm cov khoom thaum tseem tawm hauv cov ntaub ntawv zoo dua.
Cov kauj ruam tom ntej hauv kev ua tiav zaum kawg yuav suav nrog kev siv cov nonwovens, uas qhia txog lwm qhov tshwj xeeb ntawm kev ua tiav: cov txheej txheem ua haujlwm zoo tshaj plaws nrog cov cuab yeej siv hluav taws xob sib txawv.A txoj cai lub kaum ntse ntse khiav ntawm 10,000 RPM tuaj yeem ua haujlwm nrog qee cov xov xwm sib tsoo, tab sis nws yuav yaj qee cov nonwovens kom huv si.Vim li no, cov neeg ua tiav txo qhov ceev mus rau nruab nrab ntawm 3,0000 RPM thiab cov kauj ruam ua tiav ua ntej. nyob ntawm daim ntawv thov thiab consumables.Piv txwv li, nonwoven nruas feem ntau tig ntawm 3,000 thiab 4,000 RPM, thaum kho deg disks feem ntau tig ntawm 4,000 thiab 6,000 RPM.
Muaj cov cuab yeej tsim nyog (qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, cov xov xwm sib txawv) thiab txiav txim siab tus naj npawb ntawm cov kauj ruam yooj yim muab ib daim ntawv qhia uas qhia txog txoj hauv kev zoo tshaj plaws ntawm cov khoom siv thiab cov khoom tiav.Qhov tseeb txoj kev nws txawv ntawm daim ntawv thov, tab sis kev paub txog trimmers ua raws li txoj kev no siv cov txheej txheem trimming zoo sib xws.
Non-woven rollers ua tiav cov hlau stainless nto.Rau kev ua tiav zoo thiab siv tau lub neej zoo, cov xov xwm sib txawv khiav ntawm qhov sib txawv RPMs.
Ua ntej, lawv siv lawv lub sijhawm.Yog tias lawv pom ib lub workpiece stainless hlau nyias tau kub, lawv nres ua tiav hauv ib cheeb tsam thiab pib hauv lwm qhov.Los yog lawv yuav ua haujlwm rau ob qho khoom sib txawv tib lub sijhawm.Lawv ua haujlwm me ntsis ntawm ib qho thiab tom qab ntawd rau lwm qhov, muab lub sijhawm ua haujlwm rau lwm qhov kom txias.
Thaum polishing rau daim iav tiav, polisher yuav hla-polish nrog polishing nruas los yog polishing disc, nyob rau hauv ib qho kev taw qhia perpendicular mus rau yav dhau los kauj ruam.Cross sanding highlights cheeb tsam uas yuav tsum tau muab sib tov nyob rau hauv lub yav dhau los kos qauv, tab sis tseem yuav tsis tau lub nto mus rau ib daim iav tiav ntawm No. 8.Once tag nrho cov khawb tau raug tshem tawm, ib daim ntaub thiab buffing lub siab xav tau gloss.
Txhawm rau ua kom tiav qhov zoo, cov tuam txhab tsim khoom yuav tsum muab cov khoom tiav nrog cov cuab yeej tsim nyog, suav nrog cov cuab yeej siv tiag tiag thiab kev tshaj tawm, nrog rau cov cuab yeej sib txuas lus, xws li tsim cov qauv qauv los txiav txim siab seb qhov ua tiav yuav tsum zoo li cas.Cov qauv no (tshaj tawm ze ntawm lub tuam tsev ua tiav, hauv cov ntaub ntawv kev cob qhia, thiab hauv cov ntaub ntawv muag khoom) pab tau txhua tus ntawm tib nplooj ntawv.
Hais txog cov cuab yeej siv tiag tiag (nrog rau cov cuab yeej hluav taws xob thiab cov xov xwm abrasive), cov duab ntawm qee qhov chaw tuaj yeem nthuav tawm cov kev cov nyom txawm rau cov neeg ua haujlwm paub ntau tshaj plaws hauv chav ua haujlwm tiav.Qhov no yog qhov chaw uas cov cuab yeej muaj peev xwm pab tau.
Piv txwv tias tus neeg teb xov tooj yuav tsum ua kom tiav cov hlau stainless nyias-walled tubular los ua ke.Siv nrov plig plawg discs lossis txawm nruas tuaj yeem ua teeb meem, ua rau overheating, thiab qee zaum txawm tsim ib qho chaw tiaj tus ntawm lub raj nws tus kheej.Ntawm no, siv sanders tsim rau tubing tuaj yeem pab tau.Cov siv conveyor siv qhwv ib ncig ntawm feem ntau ntawm cov yeeb nkab txoj kab uas hla, nthuav tawm cov ntsiab lus ntawm kev sib cuag. thaj chaw sib txawv kom txo tau cov cua sov ntau dhau thiab tsis txhob bluing.
