Ua raws li ntau qhov kev thov tam sim no kuv tab tom ntxiv cov duab kos ntawm Magnabend centreless hinges rau lub vev xaib no.
Thov nco ntsoov tias cov hinges no nyuaj dhau los ua rau lub tshuab ib zaug..
Qhov tseem ceeb ntawm pob khawm yuav tsum raug casting (piv txwv li los ntawm cov txheej txheem peev) los yog machining los ntawm NC txoj kev.
Hobbyists yuav tsum tsis txhob sim ua qhov pob khawm no.
Txawm li cas los xij manufacturers yuav pom cov duab kos no pab tau zoo heev.
(Rau qhov yooj yim rau kev tsim pob khawm qhov nyuam qhuav tsim HEMI-HINGE tau pom zoo. Saib cov lus piav qhia thiab kos duab ntawm no).
Lub Magnabend CENTRELESS COMPOUND HINGE tau tsim los ntawm Mr Geoff Fenton thiab nws tau patented hauv ntau lub tebchaws.(Cov patents tau tas sijhawm lawm).
Qhov tsim ntawm cov pob khawm no tso cai rau lub tshuab Magnabend kom qhib tag nrho.
Lub beam dabtsi yog khoov pivots nyob ib ncig ntawm ib tug virtual axis, feem ntau me ntsis saum toj no lub chaw ua hauj lwm ntawm lub tshuab, thiab lub beam yuav viav vias los ntawm ib tug tag nrho 180 degrees ntawm kev sib hloov.
Hauv cov duab kos thiab cov duab hauv qab no tsuas yog pom ib lub pob khawm nkaus xwb.Txawm li cas los xij txhawm rau txhawm rau txheeb xyuas lub pob khawm yam tsawg kawg 2 lub rooj sib txoos pob khawm yuav tsum tau teeb tsa.

Daim duab hauv qab no yog muab los ntawm 3-D qauv ntawm pob khawm.
Los ntawm txhaj rau "STEP" cov ntaub ntawv hauv qab no: Mounted Hinge Model.step koj yuav tuaj yeem pom 3D qauv.
(Cov Apps hauv qab no yuav qhib .step cov ntaub ntawv: AutoCAD, Solidworks, Fusion360, IronCAD lossis hauv "tus saib" rau cov apps).
Nrog rau 3D qauv qhib koj tuaj yeem saib ntawm qhov chaw los ntawm txhua lub kaum sab xis, zoom kom pom meej, lossis ua kom qee qhov ploj mus thiaj li tuaj yeem pom lwm qhov kom pom tseeb dua.Koj tuaj yeem ua qhov ntsuas ntawm ib qho ntawm qhov chaw.

Cov khoom siv Mounting Block yog AISI-1045.Cov pa roj carbon siab no yog xaiv rau nws lub zog siab thiab tsis kam mus rau swaging nyob ib ncig ntawm lub pob khawm lub qhov.
Thov nco ntsoov tias lub pob khawm mounting thaiv no yog tsim los kom ruaj khov los ntawm kev vuam mus rau cov hlau nplaum lub cev tom qab kev sib tw zaum kawg.
Kuj tseem nco ntsoov cov lus qhia tshwj xeeb rau cov xov ntiav hauv lub qhov rau lub pob khawm.Cov xov no muab cov channel rau wick-in Loctite uas yog siv thaum lub rooj sib txoos pob khawm.(Lub pob khawm pins muaj lub siab nyiam ua haujlwm tshwj tsis yog tias lawv raug kaw zoo).

BOLTED-ON HINGES
Nyob rau hauv cov duab kos thiab cov qauv saum toj no lub rooj sib txoos pob khawm yog bolted rau Bending Beam (ntawm cov ntsia hlau hauv Sector Block) tab sis qhov txuas rau Magnet Lub Cev yog nyob ntawm bolting THIAB vuam.
Lub pob khawm sib dhos yuav yooj yim dua rau kev tsim thiab nruab yog tias tsis xav tau vuam.
Thaum lub sij hawm txhim kho pob khawm peb pom tias peb tsis tuaj yeem tau txais kev sib txhuam txaus nrog bolts ib leeg los lav tias lub mounting thaiv yuav tsis plam thaum cov khoom siv hauv cheeb tsam siab.
Lus Cim: Cov shanks ntawm cov bolts lawv tus kheej tsis tiv thaiv plam ntawm Mounting Thaiv vim tias cov bolts nyob rau hauv qhov loj.Clearance nyob rau hauv lub qhov yog tsim nyog los muab kev hloov kho thiab me me inaccuracies nyob rau hauv txoj hauj lwm.
Txawm li cas los xij peb tau muab tag nrho bolted-on hinges rau ntau yam tshwj xeeb Magnabend cov cav tov uas tau tsim los rau cov kab ntau lawm.
Rau cov tshuab no cov pob khawm loads yog nruab nrab thiab tau txhais tau zoo thiab yog li bolted-on hinges ua haujlwm zoo.
Hauv daim duab hauv qab no Mounting Block (xiav xim) tau tsim los txais plaub M8 bolts (tsis yog ob lub M8 bolts ntxiv rau vuam).
Qhov no yog tus tsim siv rau cov kab ntau lawm Magnabend tshuab.
(Peb tau ua txog 400 ntawm cov tshuab tshwj xeeb ntawm ntau qhov ntev feem ntau thaum xyoo 1990).
Thov nco ntsoov tias sab sauv ob lub M8 bolts kais rau hauv pem hauv ntej ncej ntawm lub cev hlau nplaum uas tsuas yog 7.5 hli tuab nyob rau hauv cheeb tsam hauv qab pob khawm.
Yog li cov ntsia hlau no yuav tsum tsis pub tshaj 16 hli ntev (9 hli hauv lub mounting thaiv thiab 7 hli hauv lub cev hlau nplaum).
Yog tias cov ntsia hlau tau ntev lawm ces lawv yuav cuam tshuam rau Magnabend kauj thiab yog tias lawv luv dua ces yuav tsis muaj xov ntev ntev, txhais tau hais tias cov xov yuav strips thaum cov ntsia hlau tau torqued rau lawv qhov nro (39 Nm).
Mounting Thaiv rau M10 Bolts:
Peb tau ua qee qhov kev sim qhov twg qhov mounting thaiv qhov loj kom txais M10 bolts.Cov bolts loj no tuaj yeem ua rau lub zog siab dua (77 Nm) thiab qhov no, ua ke nrog kev siv Loctite # 680 nyob rau hauv lub mounting thaiv, ua rau muaj kev sib txhuam ntau tshaj los tiv thaiv plam ntawm lub mounting block rau tus qauv Magnabend tshuab (nyob rau khoov mus txog 1.6mm steel).
Txawm li cas los xij, qhov kev tsim no xav tau qee qhov kev kho kom zoo thiab kev sim ntau dua.
Daim duab hauv qab no qhia txog lub pob khawm txuas rau lub cev hlau nplaum nrog 3 x M10 bolts:
Yog tias cov chaw tsim khoom xav paub ntau ntxiv txog lub pob khawm tag nrho, thov hu rau kuv.
