Khoov ib lub raj hlau suab yooj yim. Nqa ib lub raj, siv lub zog, ua kom nws ua ib qho nkhaus. Tab sis leej twg uas tau ua hauj lwm nrog tubing paub qhov tseeb yog deb messier. Ib qho khoov uas zoo nkaus li huv ntawm sab nraud tuaj yeem nkaum qhov nyias nyias, ntu ntu, thiab kev ntxhov siab uas ntsiag to tsis muaj zog.
Qhov no yog ib qho yooj yim - hom lus saib qhov ua tsis ncaj ncees lawm thaum cov hlab puag ncig tau khoov - thiab vim li cas qhov tseeb tseem ceeb dua li cov neeg feem coob paub.
Dab tsi "Round Tube Bending" Tiag tiag
Round tube dabtsi yog khoov yog cov txheej txheem ntawm shaping hollow hlau raj rau hauv cov nkhaus du. Cov txiaj ntsig tau muaj nyob txhua qhov chaw: tsheb kauj vab ncej, lub tsheb tso tsheb, tuav, rooj tog zaum, cov khoom siv hauv chaw ua si.
Tsis zoo li khoov ib qho khoom, lub raj yog hollow. Lub chaw khoob ntawd yog qhov ua rau txoj haujlwm tsis yooj yim. Cov phab ntsa hlau yuav tsum ncab, ncab, thiab tuav lawv cov duab ib zaug - thiab tsis muaj dab tsi sab hauv los txwv tsis pub lawv tawm hauv.
Lub hom phiaj yog qhov huv si, muaj zog nkhaus. Tau txais qhov ntawd txhais tau tias tswj hwm ntau lub zog sib tw tib lub sijhawm.
Lub Taub Hau Kev Kho Mob
Thaum lub raj khoov, cov hlau tsis coj tus yam ntxwv. Sab nraud ntawm qhov nkhaus thiab sab hauv kev muaj kev ntxhov siab sib txawv kiag li, thiab tus ntoo khaub lig puag ncig -section xav kom distort.
Plaub qhov teeb meem tshwm sim dua. Cia peb rhuav txhua tus hauv txhua hnub.
Tube Phab Ntsa Thinning ntawm Sab Nraud
Daim duab sab nraud ntawm qhov khoov. Raws li lub raj nkhaus, cov hlau ntawm ntug sab nrauv yuav tsum tau mus ntev dua, yog li nws ncab. Thaum hlau stretches, nws tau thinner.
Qhov no tube phab ntsa thinning yog ib qho kev txhawj xeeb tiag tiag. Yog tias phab ntsa thins tawm ntau dhau lawm, lub raj poob lub zog nyob qhov twg nws khoov - feem ntau yog qhov chaw uas nws yuav tsum muaj zog tshaj plaws. Nyob rau hauv qhov xwm txheej hnyav, cov phab ntsa sab nrauv stretches kom deb li deb nws tawg lossis tawg.
Cov kws ua haujlwm saib xyuas qhov no kom ze, tshwj xeeb tshaj yog nyob rau ntawm qhov khoov nruj thiab nyias dua - cov phab ntsa phab ntsa qhov twg cov npoo ntawm qhov yuam kev me me zuj zus.
Wrinkling thiab Collapse ntawm Inner Curve
Tam sim no saib sab hauv ntawm tib lub khoov. Cov hlau nyob ntawd ntsib qhov teeb meem sib txawv. Nws tau compressed vim nws muaj tsawg dua los npog, thiab compressed hlau tsis muaj qhov twg mus.
Qhov tshwm sim yog wrinkling - sab hauv phab ntsa puckers rau hauv ripples los yog folds. Qhov kev nkhaus nruj dua, qhov hnyav dua. Qhov no khoov vojvoog wrinkling qhov teeb meem yog ib qho ntawm feem ntau yog vim li cas ib qho tiav tau txais tsis lees paub.
Nyob rau hauv cov xwm txheej hnyav koj tau tawg tam sim ntawd, qhov chaw sab hauv phab ntsa folds rau ntawm nws tus kheej thiab rhuav tshem lub raj tag nrho.
Ovality: Thaum Round mus Oval
Nov yog qhov hloov maj mam. Ib lub raj zoo kawg nkaus zoo li flatten rau hauv ib qho oval zoo li nws khoov. Tus ntoo khaub lig-sections squashes, poob nws ncig profile.
Zoo ovality deformation tswj kom lub raj puag ncig ntawm qhov nkhaus. Qhov no tseem ceeb rau qhov chaw uas yuav tsum tau txuas mus rau lwm cov khoom sib txuas - ib qho flattened seem yooj yim yuav tsis haum lossis kaw kom zoo.
Nws kuj cuam tshuam rau lub zog thiab qhov tsos. Lub tes tuav nrog pom oval khoov zoo li pheej yig, txawm tias nws ua haujlwm zoo.
Springback: Lub raj uas yuav tsis nyob twj ywm
Koj khoov lub raj mus rau 90 degrees, tso nws, thiab nws rov qab mus rau 87 degrees. Qhov kev ntxhov siab me me rov qab yog qhov rov qab.
Hlau muaj lub cim xeeb ntawm kev xaiv. Thaum koj khoov nws, ib feem ntawm deformation yog ruaj khov, tab sis ib feem yog elastic - nws xav snap rov qab mus rau qhov qub. Tswj mandrel dabtsi yog khoov springback txhais tau hais tias cia siab tias rov qab thiab overbending txaus kom lub raj nyob ntawm lub kaum sab xis.
Cov hlau sib txawv rov qab los ntawm qhov sib txawv. Yog vim li cas qhov tseeb ntawm no xav tau ob qho tib si kev paub thiab kev suav.
Yuav Ua Li Cas Cov Pros Khaws Nws Hauv Kev Tswj
Qhov xwm zoo: tsis muaj ib qho teeb meem no tsis paub tsis meej. Cov neeg tsim khoom tau tsim txoj hauv kev txhim khu kev qha kom cov raj puag ncig, muaj zog, thiab raug. Nov yog li cas.
Mandrel Txhawb Los ntawm Sab Hauv
Cov txheej txheem zoo tshaj plaws yog txhawb nqa lub raj los ntawm sab hauv thaum nws khoov. Ib tug mandrel - hardened inserts - swb rau hauv lub raj thiab tuav cov phab ntsa nyob rau hauv qhov chaw thaum lub sij hawm khoov.
Nrog kev txhawb nqa sab hauv, lub raj tsis tuaj yeem tawg lossis mus oval yooj yim, thiab cov phab ntsa sab hauv tsis tshua muaj qhov yuav ua rau wrinkle. Lub mandrel puv qhov chaw hollow uas ua rau feem ntau ntawm cov teeb meem.
Nws kuj pab tswj cov springback, txij li lub raj yog zoo li tus precisely tiv thaiv cov cuab yeej ruaj.
Cov cuab yeej ntse thiab CNC tshuab
Cov khw niaj hnub cia siab rau automation kom sib xws. CNC yeeb nkab dabtsi yog khoov cuab yeej cia ib lub tshuab rov ua tib yam khoov ntau pua zaus yam tsis muaj drifting tawm spec.
Lub tshuab tswj lub kaum sab xis, nrawm, thiab siab, thiab nws tuaj yeem them nyiaj rau lub caij nplooj ntoo hlav raws li cov ntaub ntawv programmed. Qhov zoo ntawm repeatability yog ze li tsis yooj yim sua kom phim los ntawm tes.
Rau cov khoom tsim hauv ntim, qhov no yog qhov ua kom txhua chav saib thiab ua tau zoo ib yam.
Xaiv Cov Khoom Zoo thiab Radius
Qee lub sij hawm qhov kev txhim kho ntse tshaj plaws tshwm sim ua ntej kev khoov pib. Kev xaiv ntawm cov hlau, phab ntsa thickness, thiab khoov vojvoog ua rau muaj qhov sib txawv loj.
Softer hlau zoo li aluminium khoov yooj yim dua tab sis dents sai dua. Hlau yog tawv dua tab sis springs rov qab ntau dua. Lub vojvoog khoov dav dav yog maj mam rau ntawm lub raj, thaum lub vojvoog nruj thawb txhua qhov tsis xws luag rau nws qhov txwv.
Kev sib piv cov khoom thiab lub vojvoog rau txoj haujlwm tiv thaiv ntau yam teeb meem es tsis txhob sib ntaus sib tua tom qab.
Vim li cas qhov no tseem ceeb rau cov khoom siv niaj hnub
Tej zaum koj yuav tsis khoov lub raj koj tus kheej, tab sis koj nyob ntawm qhov zoo - khoov raj tas li. Lub thav duab ntawm koj lub tsheb kauj vab, yob tawb hauv lub tsheb, railing ntawm lub staircase, ob txhais ceg ntawm koj lub rooj zaum hauv chaw ua haujlwm, txhua tus cia siab rau khoov uas tuav lawv cov duab thiab lub zog.
Thaum lub raj khoov ua tiav tsis zoo, cov khoom lag luam ua tsis tiav ntawm txoj hauv kev los ntawm kev ntxhov siab mus rau qhov txaus ntshai. Ib tug wrinkled pa yeeb nkab txwv tsis pub ntws. Ib qho thinned khoov ntawm ib qho qauv tuaj yeem tawg hauv qab load.
Yog li lub sijhawm tom ntej koj pom cov hlau nkhaus du, paub tias qhov xav tsis thoob ntawm engineering tau nkag mus ua kom nws tsis muaj zog.
Cov lus nug nquag
Q: Vim li cas Tubes tawg lossis tawg thaum khoov?
A: Cracking feem ntau yog los ntawm cov phab ntsa sab nrauv stretching nyias heev thaum lub sij hawm khoov. Thaum lub vojvoog nruj dhau los yog cov khoom raug thawb dhau los ntawm nws qhov kev txwv, cov phab ntsa nyias nyias tsis tuaj yeem tuav ua ke thiab sib cais qhib.
Q: Puas Muaj Lub Tube tuaj yeem khoov rau txhua lub kaum?
A: Tsis heev. Txhua lub raj muaj qhov txwv tsis pub siv los ntawm nws cov khoom siv, phab ntsa thickness, thiab qhov tsawg kawg nkaus khoov vojvoog nws tuaj yeem ua tau. Thawb dhau cov kev txwv no thiab koj tau wrinkling, flattening, los yog tawg. Ib qho kev nkhaus nruj dua ib txwm xav tau kev txhawb nqa ntau dua thiab cov cuab yeej zoo dua.
Q: Dab tsi yog qhov teeb meem feem ntau hauv Tube dabtsi yog khoov?
A: Ovality thiab wrinkling saum cov npe. Tubes ib txwm xav kom flatten rau hauv lub oval thiab pucker ntawm sab hauv nkhaus, tshwj xeeb tshaj yog tsis muaj kev txhawb nqa sab hauv. Ob leeg feem ntau yog tswj nrog lub mandrel thiab cov cuab yeej tsim nyog.
Q: Puas yog tes dabtsi yog khoov raws li lub tshuab dabtsi yog khoov?
A: Rau precision thiab sib xws, CNC tshuab yeej meej. Tes dabtsi yog khoov ua haujlwm zoo rau ib qho -tawm lossis cov haujlwm ntxhib, tab sis nws nyuaj rau rov ua cov kaum ntse ntse lossis them nyiaj rau lub caij nplooj ntoo hlav. Thaum nruj tolerances teeb meem, automated tooling yog qhov kev xaiv txhim khu kev qha.
