Yuav ua li cas ua polyurethane tsheb xeem?
Xav tau los tsim polyurethane (PU) ntu rau tsheb? Seb nws yog bushings, ntsaws ruaj ruaj, los yog cov dampers, ntawm no yog yuav ua li cas ua nws - tsis muaj kev twv.
1. Pib nrog cov khoom siv yog
Tsis yog txhua tus pu yog tsim sib npaug. Rau tsheb seem, tsom rau:
Puas Txhob Ua Haujlwm-Resistant Qib: Rau cov khoom siv xws liPu BushingslossisRaug tshem tawm Mountsuas lub ntsej muag ntawd tsis sib txhuam.
Kub-Kub Kuj: Cav qaum xeem (piv txwv li,Cov Ntsaws Ruaj Ruaj) Yuav tsum tau tiv thaiv kom muaj cua sov (nce txog 120 degree +).
Roj & Tshuaj Lom: Zam kom tsis txhob o tuaj rau hauv cov roj lossis roj nplua nyeem.
Pro taub: SivCov Khoom Siv Ua Haujlwm SiabnyiamThermoplastic Polyurethane (TPU)Rau qhov uas xav tau hloov + ruaj khov.
2. Tsim kev ua haujlwm (tsis yog zoo nkaus li)
Rov qab Enteracert Cov Chaw Muaj Khoom: Scan lossis ntsuas cov khaub ncaws hnav tawm (piv txwv li,Tswj Armance Bushings) kom rov ua dua qhov ntev.
Txhim kho phab ntsa tuab: Huab tuab=tsis tseem ceeb. Dhau dhau =} ua kom tawg nyob rau hauv kev ntxhov siab. Taw rau 5-15mm, nyob ntawm kev thauj khoom.
Suav nrog cov cua ntsawj: 1-3 daim ntawv kawm tiav pab kom cov qhov chaw uas yooj yim.
Tus yam ntxwv: Redesigning ib tawgCav Mount? Ntxiv cov ntsiab lus rau kev txhawb nqa ntxiv tsis muaj ntau.
3. Xaiv koj cov qauv moulding
A. Siv cov zis (tsawg cov khoom ntim)
Zoo tshaj plaws rau: Prototypes lossisTsawg-ntim ntau lawm(10-500 units).
Kev ua:
Tsim cov silicone lossis txhuas pwm los ntawm koj tus qauv ua qauv.
Sib tov kua pu resin + tus neeg saib xyuas tus kheej.
Ncuav rau hauv pwm, degas (tshem tawm cov pa npuas tshem tawm), thiab kho kom huv.
Zoo: Tus nqi pheej yig rau cov khoom me me, zoo rau cov duab nyuaj.
Nplij txwv: Qeeb dua li kev txhaj tshuaj molding.
B. Txhaj Tshuaj Molding (High-Ntim)
Zoo tshaj plaws rau: Cov pawg ntau lawm (1, 000+ units).
Kev ua:
Tshuab hlau lossis txhuas pwm.
Qhuav khoom pu pellets thiab txhaj rau hauvKaw Mouldnyob rau hauv kev kub siab.
Txias, eject, thiab txiav.
Zoo: Nrawm, zoo ib yam, zoo tagnrho rauQhov Tseeb Tshwj Xeeb.
Nplij txwv: High upfront pwm nqi.
4. Tsim lossis qhov chaw ua kom haum pwm
Ntaub ntawv:
Txhuas pwm: Pheej yig, zoo rau prototypes lossisNrum Urethane Partse.
Pwm: Ruaj khov rauTxhaj Tshuaj Moldingntev khiav.
Cov ntsiab lus tseem ceeb:
Ntxiv cov vents los tiv thaiv cov ntxiab cua.
Siv pwm tso tawm (piv txwv li, silicone-based) rau kev cuam tshuam yooj yim.
Tau txais lub sijhawm: Ib tus neeg siv khoom sib tsoo pwm vents-lawvPank Kev Ncua Ntawv Bushingsmuaj cua hnab ris. Peb tsau nws los ntawm kev ntxiv micro-channel.
5. Sib tov, ncuav, lossis txhaj
RAU CAMETING:
Ntsuas Resin + Hardenermeej(Siv cov nplai digital).
Tshem maj mam kom tsis txhob muaj npuas.
Ncuav rau hauv pwm nyob rau hauv ib lub nkuaj.
Kev Txhaj Tshuaj Molding:
Teeb lub tshuab rau lub samp raug (nws txawv dua los ntawm qib qib).
Saib siab rau kev sau cov kab noj hniav tusyees.
Kev Nyab Xeeb Ua Ntej: Hnav looj tes thiab goggles-uncured pu yog tshuaj lom.
6. Kho & Demold
Kho lub sijhawm:
Nrum urethane: 4-24 teev (nyob ntawm cov tuab).
Txhaj-moulded: 1-5 feeb (sai dua txias).
Kev puas tsuaj:
Maj mam flex cov pwm lossis siv cua compressed los pop ib feem tawm.
Trim flash (cov khoom siv ntau dhau) nrog rab chais lossis CNC TRIMMER.
Hack: Sov lub pwm me ntsis (50-60 degree) kom kho tau sai.
7. Kev ua haujlwm
Nto Xov Xwm:
Xuab zeb npoo rau smoothness (pib nrog 120- grit, tiav nrog {1} {1} grit).
Ua ntaub ntawvCov Khaub Ncaws Polyurethane Tshorau UV kev tiv thaiv lossis xim.
Cov tshev mis zoo:
Kuaj hardness nrog lub durometer (piv txwv li, 70a rau cov khoom muag muag muag, 90a rau cov mounts rigids).
Kev ntsuas cov khoom tseem ceeb (piv txwv li, simulation 10, 000} compression Cycles).
8. Kuaj hauv cov xwm txheej tiag tiag
Ua ntej kawg:
Ntsuas Cua Sov: Ci seem ntawm 10 degree saum toj no max operating temp rau 24 teev.
Kev Siv Tshuaj: Soak hauv roj lossis txias rau 48 teev. Kuaj xyuas o.
Yam: Kuaj-nruab rau ntawm lub tsheb.
Kev Kawm Txog: Pawg neeg sib twKev Cai Pu Lub Cev Muaj ZogUa tsis tiav raws li kev co. Peb tau hloov mus rau cov fiber ntau txhawb kev sib txuas-xoom teeb meem tom qab sib tw.
Cov kev ua yuam kev (thiab yuav ua li cas kom tsis txhob lawv)
Tsis ncaj ncees lawm cov khoom siv xaiv: Siv cov muag muag muag rau load-cov kabmob.
Kho: Qhia cov hardness (ntug dej A / d) upfront.
Tsis quav ntsej pwm pov: Pu shrinks 1-3% thaum kho.
Kho: Teev cov pwm tsim raws li.
Rush tshuaj kho: Nplaum, ib nrab-cured qhov chaw ruin kev thev taus.
Kho: Ua raws cov chaw tsim khoom tsim khoom siv sijhawmib yam li ntawd.
DIY Vs. Kev Raug Tsim Kho
DIY: Tau yooj yimNrum Urethane Partse(piv txwv li, qhov rooj ntsaws ruaj ruaj) nrog cov pwm sib xyaw silicone.
Pab kev pab xav tau:
High-precision Cheebtsam (piv txwv li,Hloov Chaw).
Qhov uas yuav tsum taupuas ualossis cov geometries lossis nyuaj.
Nqi Piv Txwv:
DIY: $ 50- $ 200 (cov ntaub ntawv + cov pwm me me).
Kev: $ 500- $ 5, {2}} (nyob ntawm kev txua thiab ntim).
