Yuav ua li cas xaiv cov hlau 3D luam ntawv tsim los tsim pwm?

1. Kev xaiv cov ntaub ntawv txiav txim los ntawm daim ntawv thov scenarios: ntau yam xav tau kev txhaj tshuaj molding thiab tuag casting
Lub ntsiab tseem ceeb uas txiav txim siab txog cov khoom siv yog hom pwm thiab nws yuav siv li cas. Cov txheej txheem sib txawv muaj ntau yam kev xav tau rau cov khoom siv:
Kev txhaj tshuaj pwm yuav tsum muaj peev xwm tswj tau qhov kub thiab txias ntawm cov yas yaj. Cov khoom siv yuav tsum muaj peev xwm ua kom sov tau zoo, tiv thaiv corrosion, thiab tiv taus thermal qaug zog. Piv txwv li, lub tsheb sab hauv pwm siv 316L stainless hlau hmoov, thiab kev tsim kho ntawm cov dej txias txias channel ua rau lub voj voog txhaj tshuaj molding los ntawm 120 vib nas this mus rau 75 vib nas this, nce tus nqi tawm mus rau 98%. XM-7 pwm steel hmoov, uas muaj cov thermal conductivity ntawm 30W / (m · K), tuaj yeem ua kom txias ntawm cov khoom thiab txhawb cov txheej txheem tshuaj corrosion tom. Qhov no ua tau raws li qhov kev xav tau zoo ntawm cov qauv ntiav (qhov tob<0.12mm).
Tuag casting pwm: Nws yuav tsum muaj peev xwm ua tau siab -kub hlau ua kua dej yaig thiab thermal stress cycles. Cov khoom siv kuj yuav tsum muaj zog heev, hnav-resistant, thiab tiv taus tawg los ntawm tshav kub. Vim nws cov cua sov kho hardness ntawm 50–52HRC, 1.2709 (18Ni300) martensitic aged steel hmoov tau dhau los ua qhov kev xaiv zoo tshaj plaws rau txhuas alloy tuag-casting pwm. Siv cov khoom no hauv cov tuag-casting pwm ntawm ib lub tsheb cav lub tog raj kheej tau txhim kho pwm lub neej los ntawm 20,000 siv mus rau 60,000 siv thiab txiav tus nqi ib thooj los ntawm 40%.
Roj hmab log pwm: Cov qauv thaiv yuav tsum yog qhov tseeb thiab tiv taus hnav, thiab lawv yuav tsum tau tswj cov cua sov deformation kom cov khoom tsis txhob flashing. SLM thev naus laus zis siv los luam CX (Corrax) stainless hlau hmoov pwm muab nws lub peev xwm polishing mus txog qib A2. Cov pwm qhov hnyav yog txiav los ntawm 30% ua tsaug rau qhov kev txhawb nqa lattice zoo, thiab qhov tseeb ntawm cov qauv rov ua dua yog txhim kho kom tsis pub dhau 0.01 hli.
2. Sib piv cov khoom ntawm cov khoom siv: Plaub lub ntsiab lus qhia txog kev txwv rau kev ua haujlwm.
Plaub yam yuav tsum raug coj mus rau hauv tus account thaum ntsuas qhov ua tau zoo ntawm cov khoom pwm: cov khoom zoo, thermal zog, corrosion kuj, thiab cov txheej txheem adaptability.
Cov yam ntxwv ntawm cov tshuab: Cov pwm lub peev xwm los tuav qhov hnyav yog nyob ntawm nws lub zog tensile, lub zog tawm los, thiab elongation thaum tawg. Piv txwv li, 1.2709 hmoov muaj lub zog tensile ntawm 2000MPa, uas ua rau nws zoo rau kev tuag- cov xwm txheej uas muaj kev ntxhov siab ntau heev. 316L hmoov muaj cov pob txha elongation ntawm 45%, uas ua rau nws zoo dua rau nyias - phab ntsa txhaj tshuaj pwm uas yuav tsum muaj zog.
Nws ua haujlwm zoo npaum li cas hauv tshav kub: Qhov kev ua kom txias thiab qhov ruaj khov yog cuam tshuam los ntawm thermal conductivity thiab thermal expansion coefficient. XM-7 pwm hlau muaj cov thermal conductivity uas yog 100% siab dua 316L. Qhov no tuaj yeem ua rau luv luv ntawm kev txhaj tshuaj molding voj voog. Invar 36 alloy (nrog thermal expansion coefficient ntawm 1.2 × 10⁻⁶ / degree) yog siv rau cov pwm kho qhov muag kom lawv tsis txhob poob qhov tseeb vim thermal deformation.
Corrosion resistance: Yog tias koj xav tiv thaiv cov yas corrosive xws li PVC thiab PA, xaiv cov hlau tsis muaj chromium siab . 316L hmoov muaj 17% chromium, uas yuav pab kom cov chaw du nyob rau hauv cov av noo thiab txo qhov xav tau kev saib xyuas.
Adaptability ntawm cov txheej txheem: Qhov zoo ntawm cov luam ntawv yog cuam tshuam los ntawm cov hmoov cov flowability, oxygen cov ntsiab lus, thiab sphericity. Piv txwv li, cov hmoov uas muaj qhov loj me me ntawm 15-53 μm tuaj yeem tshem tawm cov kev tsis sib haum xeeb uas tshwm sim thaum cov hmoov tsis sib xws. Qhov cuam tshuam toughness ntawm 316L hmoov nrog cov pa oxygen tsawg dua 100PPM yog 44% siab dua li cov khoom siv niaj hnub, uas ua rau lub neej ntev ntawm cov pwm.
3. Adaptability ntawm tus txheej txheem: ua hauj lwm ua ke los txhim kho cov cuab yeej thiab post- ua
Cov kev xaiv ntawm cov ntaub ntawv yuav tsum tau ua tib zoo koom tes nrog cov txheej txheem luam ntawv thiab ntws ntawm ncej- ua:
Compatibility ntawm cov cuab yeej: txawv hlau 3D luam ntawv technologies xav tau cov ntaub ntawv sib txawv. Cov txheej txheem SLM ua haujlwm zoo nrog cov ntaub ntawv uas muaj lub siab melting point, xws li titanium alloys thiab 1.2709. Txoj kev sib tw jetting ua haujlwm zoo dua nrog cov hlau pheej yig -raws li hmoov. Piv txwv li, ib lub tuam txhab ua ZY6061 aluminium alloy hmoov uas tuaj yeem luam tawm ruaj khov ntawm EOS M290 cov cuab yeej los ntawm kev txhim kho kev faib tawm ntawm cov khoom me me thiab ntws. Qhov no daws qhov teeb meem ntawm kev tawg hauv 6-series aluminium alloys tsis tu ncua.
Yuav ua li cas kho cua sov: Yuav kom tshem tawm cov seem seem thiab txhim kho lawv cov microstructure, cov ntaub ntawv luam tawm yuav tsum tau ua kom sov. Lub hardness ntawm 17-4PH stainless hlau hmoov tuaj yeem ncav cuag 42HRC tom qab hnub nyoog ntawm 480 degree, uas kuj tau tshem tawm cov kab nrib pleb. Qhov cuam tshuam toughness ntawm XM-7 pwm hlau tuaj yeem nce mus rau 20J / cm ² siv cov txheej txheem quenching, thaum nws hardness nyob ntawm 30HRC.
Kev kho deg: Nyob ntawm seb cov pwm yog dab tsi, koj tuaj yeem xaiv electroplating, sandblasting, lossis tshuaj polishing. Piv txwv li, khau pwm yuav tsum tau siv nano electroplating kom tau ib daim iav nyhuv, thiab tuag- casting pwm yuav tsum tau siv sandblasting kom lub nto rougher thiab yooj yim rau tshem tawm.
4. Kev txheeb xyuas nyiaj txiag: tswj cov nqi ntawm tag nrho lub neej voj voog
Kev xaiv cov khoom siv yuav tsum muaj kev sib haum xeeb ntawm kev ua tau zoo thiab tus nqi, thiab tag nrho cov kev ntsuas lub neej yuav tsum tau siv los txo cov nqi thiab txhim kho kev ua haujlwm:
Tus nqi ntawm cov ntaub ntawv: Muaj qhov sib txawv loj ntawm tus nqi ntawm cov khoom siab - kawg. Chav tsev nqi ntawm 1.2709 hmoov yog kwv yees li 800 yuan / kg, uas yog peb npaug ntawm tus nqi ntawm 316L (260 yuan / kg). Txawm li cas los xij, nws tuaj yeem kav peb zaug ntev dua li niaj hnub H13 steel thiab pheej yig dua tag nrho. Cov txheej txheem "base grafting" tuaj yeem siv los luam tawm siab - cov ntaub ntawv ua tau zoo ntawm cov qauv pwm steel puag rau me me - nplai ntau lawm. Qhov no txo ​​cov nqi ntawm cov khoom siv.
Kev tsim khoom ua haujlwm zoo npaum li cas: Cov khoom siv hluav taws xob muaj hluav taws xob tuaj yeem ua kom lub voj voog txhaj tshuaj molding thiab ua kom zoo dua ntawm cov khoom siv. Siv XM-7 hmoov nyob rau hauv ib qho kev kho mob ntau kab noj hniav pwm tau txiav lub sij hawm nws siv los ua ib feem ntawm 45 vib nas this mus rau 30 vib nas this. Cov pwm tus nqi tau nce ntau dua 2 lab yuan ib xyoos.
Tus nqi ntawm kev saib xyuas: Cov ntaub ntawv uas tsis corrode tuaj yeem ua rau nws tsawg dua uas koj yuav tsum tau ntxuav lawv . 316L pwm tuaj yeem khaws lawv cov chaw tiaj tus txawm tias nyob rau hauv qhov chaw ntub dej, uas txo cov nqi tu los ntawm 60% piv rau P20 steel li niaj zaus.
