cov nqi sawv cev rau kev nqis peev ua ntej los tsim koj cov hlau nplaum tshwj xeeb thiab qhov ntev. Tsis zoo li tawm -- txee hlau nplaum, cov hlau nplaum kev cai xav tau cov cuab yeej ua kom haum rau koj cov geometry thiab magnetization kev taw qhia. Cov nqi cuab yeej sib txawv heev: ib qho yooj yim cov duab plaub tuaj yeem raug txiav los ntawm cov qauv Tshuag nrog tsawg kawg NRE ($ 100-$ 300), thaum lub nplhaib txhaj tshuaj complex yuav tsum muaj cov pwm tawv tawv ($ 3,000- $ 8,000). Phau ntawv qhia no piav qhia vim li cas sintered vs. bonded hlau nplaum muaj cov cuab yeej sib txawv, rhuav tshem cov nqi NRE (pwm / tuag nqi, fixturing, programing), piv cov hlau EDM txiav vs. nias pwm, muab cov nqi ntsuas rau cov duab sib txawv, thiab muaj cov tswv yim los txo tus nqi customization hauv prototyping.
Vim li cas Sintered vs. Bonded Magnets muaj cov cuab yeej sib txawv
Sintered NdFeB: Cov hlau nplaum yog nias los ntawm cov hmoov hauv qhov tuag nyob hauv qhov chaw sib nqus. Cov tuag txiav txim siab cov duab (puab, puag ncig, trapezoidal). Cov duab yooj yim (blocks, discs) xav tau tus nqi tuag ntawm $500-$1,500. Cov duab nyuaj (arcs nrog taper, ntau theem) yuav tsum tau tuag nrog zawv zawg punches, raug nqi $ 2,000- $ 5,000. Cov xovxwm tuag yog ua los ntawm cov cemented carbide, kav ntev li 100,000-500,000 qhov chaw, tom qab ntawd xav tau kev hloov lossis kho dua tshiab.
Bonded (txhaj tshuaj molded): Cov hlau nplaum yog txhaj molded hauv cov cuab yeej txhaj tshuaj yas (steel pwm). Tus nqi cuab yeej yog $3,000-$8,000 rau ib qho- kab noj hniav pwm, $10,000-$20,000 rau ntau kab noj hniav (4-8 kab noj hniav) pwm. Pwm lub neej yog 500,000-2,000,000 cycles. Kev txhaj tshuaj molding ua rau cov duab 3D nyuaj tab sis yuav tsum muaj NRE siab dua.
Flexible / Bonded (compression molded): Yooj yim compression tuag ($ 500- $ 2,000) rau cov duab yooj yim (cov ntawv, strips). Tsis muaj geometry complex ua tau.
Kev tawg ntawm NRE (Tsis yog -Recurring Engineering) Nqis
NRE nqi feem ntau suav nrog:
Tuag / pwm tsim thiab tsim khoom: Cov cuab yeej siv lub cev . 60-80% ntawm NRE.
Fixturing: Rau kev sib tsoo, slicing, lossis magnetizing cov duab kev cai . 10-20%.
Programming: Rau hlau EDM, CNC sib tsoo, los yog tshuaj xyuas (CMM) . 5-10%.
Kev teeb tsa: Rau thawj tsab xov xwm tsim, suav nrog kev tsav tsheb khiav thiab PPAP. 5-10%.
Kev xa khoom ntawm cov cuab yeej (yog tias tus neeg siv khoom muaj qhov tuag, nws raug xa mus rau lawv tom qab ntau lawm).
Peb muab cov nqi NRE hauv peb cov lus hais. Cov cuab yeej tseem tshuav peb cov cuab yeej tshwj tsis yog tus neeg siv khoom them tus nqi cuab yeej cuab tam.
Hlau EDM Txiav vs. Nias Pwm Nqi
Rau cov qauv lossis qis- ntim cov duab kev cai, xaim EDM (kev siv hluav taws xob tawm tshuab) feem ntau pheej yig dua li cov cuab yeej:
Hlau EDM: Tsis muaj tus nqi tuag. Ib feem yog txiav los ntawm tus qauv thaiv. Teeb $100-$300. Tus nqi ib feem: siab (vim txiav qeeb, 1-10 ntu / teev). Zoo tshaj rau<100 pcs.
Pressing die: High upfront die cost ($1,000-$5,000) but very low per-part cost once tooling is built. Best for >1,000 pcs.
Tus nqi sib piv (rau 20x20x10mm arc ntu, kam rau ua ± 0.05mm):
| Txoj kev | NRE Cost | Ib - Tus Nqi Them (100 pcs) | Ib - Tus Nqi Them (5,000 pcs) | Qhov Zoo Tshaj Plaws |
|---|---|---|---|---|
| Hlau EDM (tsis tuag) | $200 | $12.00 | N/A (hloov dhau) | <100 pcs |
| Nias tuag + sib tsoo | $2,500 | $6.50 | $2.80 | >1,000 pcs |
| Nias tuag (net shape, tsis sib tsoo) | $3,500 | $4.50 | $2.20 | >5,000 pcs (yog tias kam rau ua) |
Tooling nqi Index rau txawv Magnet Shapes
Cov duab complexity txiav txim siab tus nqi siv:
| Magnet Shape | Nias Die Tus Nqi kwv yees | Machining yuav tsum tau tom qab nias | Tus txheeb ze Tooling Index (vs txheem thaiv) |
|---|---|---|---|
| Rectangular block (standard qhov ntev) | $500-$800 | Sib tsoo tag nrho 6 lub ntsej muag | 1.0x |
| Disc (tus qauv OD / ID) | $600-$1,000 | Sib tsoo ntsej muag, OD | 1.2x |
| Rectangular nrog chamfer | $800-$1,200 | Sib tsoo + chamfering | 1.5x |
| Arc ntu (120℃ntu, vojvoog 50mm) | $1,500-$2,500 | Sib tsoo ID / OD, ntsej muag | 2.5x |
| Trapezoid (tapered sab) | $2,000-$3,500 | Sib tsoo tag nrho 4 sab | 3.5x |
| Ntau- kauj ruam thaiv (stepped hla-section) | $3,000-$5,000 | Sib tsoo cov kauj ruam + ntsej muag | 5.0x |
| Txhaj molded complex 3D duab | $5,000-$15,000 (pwm) | Tsis muaj (net shape) | 8.0x-15x |
Cov lus nug nquag
Q: Yog tias kuv xaj cov hlau nplaum kev cai, leej twg yog tus tswv qhov tuag / cuab yeej tom qab ntau lawm?
A: Los ntawm lub neej ntawd, cov cuab yeej tseem yog peb cov khoom. Yog tias koj xav tau cov tswv cuab tshwj xeeb, peb them tus nqi ntxiv $ 500- $ 1,500 rau tus nqi "tus tswv cuab cuab tam". Tom qab ntawd koj tau txais cov ntaub ntawv CAD thiab daim ntawv pov thawj tias cov cuab yeej yog rau koj siv tshwj xeeb.
Q: Kuv puas tuaj yeem siv tib qhov tuag rau cov qib hlau nplaum sib txawv (N35 vs. N52)?
A: Yog, qhov tuag yog geometry- tshwj xeeb, tsis yog qib- tshwj xeeb. Cov txheej txheem nias yog tib yam rau txhua qib sintered NdFeB. Koj tuaj yeem xaj tib cov duab hauv N35, N42, N52, lossis txhua qib uas siv tib lub cuab yeej. Tsis muaj NRE ntxiv rau kev hloov qib.
Q: Lub sijhawm ua haujlwm rau lub tshuab nias yog dab tsi?
A: 3-4 lub lis piam rau kev tuag yooj yim (block, disc). 5-8 lub lis piam rau kev tuag nyuaj (arc ntu, ntau kauj ruam). Peb muab kev pabcuam nrawm (2 lub lis piam) ntawm 50% tus nqi nrawm ntxiv.
