Tiv thaiv deformation hauvcua coil windingnqes los tswj peb yam ib zaug: hlau nro thaum winding, txoj kev sib khi siv los tuav lem ua ke, thiab yuav ua li cas lub kauj raug tso tawm ntawm nws mandrel - tau ib qho tsis ncaj ncees lawm thiab ibbobbinless coil windingpoob nws cov duab lub caij nws raug tshem tawm ntawm daim ntawv.
Tsis zoo li bobbin- cov kab mob, uas vam khom cov yas los yog ceramic qub rau kev txhawb nqa, tus kheej - txhawb nqa cua coils yuav tsum tsim kom muaj lawv tus kheej rigidity, feem ntau yog los ntawm tus kheej -bonding hlau qhib los ntawm tshav kub los yog hnyav thaum lub sij hawm winding txheej txheem.
Hauv qab no, peb tawg vim li cas springback tshwm sim, qhov nro lej tom qab nws, thiab kev sib txuas thiab mandrel cov txheej txheem uas ua kom lub kauj voj voog thiab nruj ntev tom qab nws tawm ntawm lub tshuab.
I. Vim li cas Bobbinless Coils poob lawv cov duab tom qab Winding?
Lub tshuab cua tsis muaj kev txhawb nqa mus tas li, yog li lub sijhawm winding nro tawm, cov hlau lub ntuj elasticity rub lub kauj rov qab mus rau nws cov duab tsis zoo - ib qho tshwm sim hu ua springback.
ib. dab tsi ua rau springback
Txhua lub xov hlau muaj qee lub cim xeeb elastic; Thaum nws khoov ib ncig ntawm lub mandrel nyob rau hauv qhov nro, ib feem ntawm qhov deformation yog elastic (ntev) es tsis yog yas (mus tas li), thiab qhov elastic feem sim thim rov qab nws tus kheej thaum lub mandrel raug tshem tawm.
b. yog vim li cas qhov no tsis zoo rau tus kheej -txhawb coils tshaj bobbin coils
A bobbin kabyeej tsis tau tawm tsam springback vim hais tias lub bobbin nws tus kheej tuav cov duab mus tas li; bobbinless coil tsis muaj dab tsi ntxiv rau kev vam khom, yog li cov txheej txheem winding thiab kev sib koom ua ke yuav tsum ua txhua yam haujlwm ntawm cov bobbin yuav txwv tsis pub.
II. Lub zog ntau npaum li cas Lub kauj yuav tsum tau tawm tsam kom nyob ib puag ncig?
Winding nro tsim qhov seem seem kev nyuaj siab nyob rau hauv lub tiav coil - tib lub zog uas pab tsim nws thaum lub sij hawm winding kuj yog lub zog ua rau lub caij nplooj ntoos hlav rov qab qhib tom qab.
Hoop stress formula:
σ = F / A
Qhov twg:
σ= residual hoop stress nyob rau hauv cov hlau (N/mm², sib npaug rau MPa)
F= Hlau nro siv thaum winding (N)
A= hlau cross-sectional area (mm²), xam li A=π × (d/2)²
Piv txwv ua haujlwm:rau 0.5mm txoj kab uas hla hlau qhov txhab ntawm 2N nro:
Luas A=π × (0.25)² ≈ 0.196 mm²
σ = 2 / 0.196 ≈ 10.2 N / mm² (MPa)
ib. tus lej no qhia koj li cas
Qhov kev ntxhov siab seem no yog qhov kev sib koom ua ke ntawm kev hloov pauv yuav tsum tiv thaiv kom lub kauj los ntawm lub caij nplooj ntoos hlav qhib - txoj kev sib txuas yuav tsum tau tuav tawm tsam qhov kev ntxhov siab ntau hauv ib cheeb tsam, uas yog vim li cas kev sib koom ua ke lub zog thiab winding nro yuav tsum tau sib phim, tsis xaiv ntawm nws tus kheej.
b. yog vim li cas siab dua tsis yog ib txwm zoo
Kev nro ntxiv txhim kho winding ceev thiab sib xws, tab sis nws kuj ua rau cov kev ntxhov siab uas nyob hauv daim ntawv cog lus yuav tsum tau kov yeej - thawb nro siab dhau yam tsis muaj kev sib raug zoo sib raug zoo ntawm kev sib koom ua ke ua rau muaj kev pheej hmoo ntawm deformation, tsis yog rov qab.
III. Txoj Kev Bonding Yuav Ua Li Cas Rau Tus Kheej -Txhawb Coil Rigid?
Tus kheej-bonding hlau yog coated nrog ib tug thib ob txheej, ntxiv rau txheej txheem enamel rwb thaiv tsev, uas activates thiab fuses nyob ib sab lem ua ke thaum tshwm sim los ntawm tshav kub, hnyav, los yog tam sim no.
| Txoj kev Bonding | Yuav ua li cas qhib | Zoo tshaj rau |
|---|---|---|
| Thaum tshav kub kub- qhib nws tus kheej- sib txuas hlau | Cua kub los yog qhov cub ncej-winding | General -lub hom phiaj cua coils |
| Cov kuab tshuaj- qhib kev sib txuas | Solvent siv thaum / tom qab winding | Coils rhiab heev rau qhov raug tshav kub |
| Tam sim no - qhib kev sib txuas | Tam sim no dhau los ntawm cov xaim tsim hluav taws xob sab hauv | Siab - cov kab ntau lawm |
| Sab nrauv varnish impregnation | Coil dipped los yog coated tom qab winding | Coils xav tau kev siv zog ntxiv |
ib. vim li cas txoj kev ua kom muaj feem cuam tshuam rau kev pheej hmoo deformation
Thaum tshav kub kub- thiab tam sim no- qhib kev sib txuas fuse tig thaum lub kauj tseem nyob ntawm lub mandrel thiab nyob rau hauv qhov nro, xauv rau hauv lub qhov txhab zoo ua ntej springback muaj feem yuav tshwm sim - kev sib txuas tom qab lub coil raug tshem tawm ntawm lub mandrel tsis tshua muaj txiaj ntsig ntawm kev tiv thaiv kev poob.
b. vim li cas daim ntawv cog lus tseem ceeb npaum li daim ntawv cog lus muaj zog
Lub kauj uas muaj zog sib txuas tsuas yog ntawm ob peb lub ntsiab lus tseem tuaj yeem deform ntawm cov chaw sib txuas, yog li kev ua kom zoo sib xws thoob plaws tag nrho cov winding - tsis yog kev sib raug zoo ntawm kev sib cais - yog qhov tseeb tiv thaiv deformation.
IV. Mandrel tsim cuam tshuam li cas coil Deformation?
Lub mandrel ib kauj yog qhov txhab ntawm qhov ncaj qha cuam tshuam rau ob qho tib si winding raug thiab yuav ua li cas kom huv si cov kauj tiav tso tawm yam tsis muaj kev cuam tshuam.
ib. mandrel khoom thiab nto tiav
Lub mandrel nrog tus du, qis - txhuam qhov chaw (feem ntau coated los yog polished) tso cai rau cov kauj tiav kom xaub tawm kom huv, thaum lub mandrel ntxhib los yog tapered tuaj yeem rub thiab distort lub coil zoo thaum tso tawm.
b. mandrel txoj kab uas hla thiab springback them nyiaj
Vim hais tias lub kauj yuav rov qab me ntsis loj dua li lub mandrel txoj kab uas hla ib zaug tso tawm, mandrels feem ntau me me me me me me ntawm lub hom phiaj tiav coil txoj kab uas hla los them rau qhov kev xav tau rov qab los.
V. Dab tsi tshuab muaj peev xwm tseem ceeb tshaj plaws rau Bobbinless Winding?
Tsim kom muaj tus kheej zoo ib yam -txhawb cov coils nyob ntawm qhov hnyav ntawm lub tshuab winding lub peev xwm los tswj kev nruj nruj thiab, qhov muaj feem xyuam, kev sib koom ua ke ua kom muaj zog rau hauv lub voj voog winding nws tus kheej.
| Tshuab muaj peev xwm | Vim Li Cas Nws Tseem Ceeb rau Cua Coils |
|---|---|
| Kaw - voj nro tswj | Ua kom cov kev ntxhov siab nyob ib puag ncig tig tig, tsis txhob muaj qhov tsis sib xws |
| Integrated tshav kub / tam sim no qhov chaw nres tsheb | Ua kom nws tus kheej-bonding hlau thaum coil tseem nyob ntawm mandrel |
| Programmable lem thiab pitch tswj | Ua kom muaj kev sib tw winding ceev thoob plaws lub kauj |
| Precision mandrel indexing | Txhawb kom huv si, rov ua dua coil tso tawm |
ib. vim li cas qhov nro sib xws tseem ceeb ntawm no dua li hauv bobbin winding
Hauv bobbin- qhov txhab coils, bobbin absorbs me ntsis nro inconsistency yam tsis muaj kev cuam tshuam cov duab kawg; nyob rau hauv bobbinless winding, txhua qhov nro variation ncaj qha txhais mus rau hauv uneven residual stress thiab inconsistent springback thoob lub coil.
VI. Qhov twg KIOXIA Tshuab Txhawb Kev Txhim Kho Cua Coil Ntau Lawm?
Raws li tus kheej- txhawb nqa coil ntau lawm nyob ntawm qhov nro precision thiab cov txheej txheem tswj kev ua haujlwm ua ke, tsis yog raw winding ceev.
KIOXIA Lub Teeb Ring Equipment Group qhov tseeb winding platforms yog tsim nrog lub kaw - voj nro tswj uas bobbinless coil ntau lawm yuav tsum tau, pab kom muaj kev ntxhov siab nyob rau hauv txhua lub kauj nyob rau hauv ib tug ntau lawm khiav.
Rau cov chaw tsim khoom ua haujlwm nrog tus kheej- kev sib txuas cov hlau thiab cov duab nruj- tuav lub siab ntev, ua haujlwm ncaj qha nrog cov neeg paub txogcoil winding tshuab manufacturersntawm qhov nro qhov chaw thiab xaiv mandrel feem ntau yog dab tsi cais ib puag ncig ib puag ncig ntawm ib qho yooj yim rau deformation tom qab tso tawm.
