Ib pawg ntawm cov hlau brackets tuaj txog. Lub zuag qhia tag nrho cov duab zoo li tau txais, tsis tau lub bolt qhov tsis kam ua kab. Qee qhov diameters loj, lwm tus khiav me me. Kev sib dhos nres, cov khoom rov qab rau kev ua haujlwm dua, thiab cov ntawv teev sijhawm.
Qhov teeb meem tseem ceeb yog qhov yooj yim: tag nrho cov ntawv luam tawm thiab qhov tseeb ntawm qhov tsis zoo ib yam. Ib feem tuaj yeem ua tau raws li lub ntiaj teb qhov ntev thaum nws qhov tseem ceeb thiab lawv qhov sib txawv txav sab nraum qhov siab ntev.
Yog vim li cas qhov qhov tseeb txawv ntawm tag nrho cov luam ntawv raug
Hlau 3D luam ntawv tsim txheej los ntawm txheej. Cov txheej txheem ntawd kis kev kam rau siab sib txawv ntawm CNC machining. Lub ntiaj teb qhov ntev feem ntau nyob hauv ± 0.1-0.2 hli, tab sis cov yam ntxwv hauv zos xws li lub qhov tuaj yeem tuaj yeem ua yuam kev ntxiv los ntawm shrinkage, kub gradients, thiab txheej txheej.
Hauv SLM lub pas dej ua ke thiab lub voj voog txias ua rau muaj kev ntxhov siab. Qhov-tshwj xeeb tshaj yog cov thaum uas tig mus rau kev tsim cov kev taw qhia-nqhis ntau dua li sab nraud.Muaj MJF Printing(polymer) qhia tau hais tias isotropy zoo dua thiab qis dua qhov kev ntxhov siab, ua rau nws muaj txiaj ntsig zoo rau kev siv thev naus laus zis sai thiab lub teeb - lub luag haujlwm brackets. Txawm li ntawd los, hmoov adhesion thiab me me txoj kab uas hla variation tseem tshwm sim. Cov txheej txheem tsis sib xws rau qhov nruj, qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas uas CNC reaming lossis tho txawv xa.
Cov ntsiab lus tsis ua haujlwm feem ntau:
Raws li - ua lub qhov taub ntawm cov hlau SLM feem ntau poob rau hauv± 0.1 ~ 0.3 hlintau rau txoj kab uas hla hauv qab 10 mm. Tom qab tsim nyog ncej-machining tib lub qhov tuav± 0.01 ~ 0.05 hli. Qhov kev sib txawv ntawd yog qhov uas feem ntau qhov kev sib dhos tsis ua haujlwm pib.
Qhov Tiag Tiag Ua Rau Lub Qhov Ncauj Qhov Ncauj thiab Qhov Ncauj Tsis Txaus
Plaub yam feem ntau ua ke:
Khoom siv Shrinkage
Hlau hmoov cog lus thaum lub sij hawm solidification thiab kev kho cua sov; tus nqi hloov nrog alloy thiab geometry.
Txhawb Qhov Nyob ze
Kev txhawb nqa sab hauv lossis ze ntawm qhov raug tshem tawm tawm cov qhab nia lossis txwv tsis pub shrinkage thiab tsim kev cuam tshuam hauv zos.
Scan Path & Txheej Thickness
Thicker khaubncaws sab nraud povtseg nce ntaiv-stepping ntawm nkhaus phab ntsa; tsis sib xws scan kub tuaj yeem rub ib sab ntawm ib lub qhov.
Thermal Stress hla ntu
Cov khaubncaws sab nraud povtseg txias thiab lub bracket warps me ntsis. Qhov -rau- qhov sib nrug qhov yuam kev yog yuav luag txhua qhov tshwm sim ntawm qhov kev txav mus thoob ntiaj teb no.
Tsuas yog qhov loj ntawm txhua lub qhov tsis tshua kho qhov teeb meem sib nrug. Lub hauv paus zaum hauv keeb kwm thermal ntawm kev tsim.
Yuav Ua Li Cas Kho Nws - Tsim, Txheej Txheem, thiab Tshaj Tawm -Machining
Tsim-Kev them nyiaj rau theem
Ntxiv cov kev tswj hwm offset rau txhua qhov tseem ceeb (feem ntau +0.2 rau +0.4 mm nyob ntawm cov khoom thiab kev taw qhia). Khaws qhov tseem ceeb ntsug kom txo tau ovality. Cov alloys sib txawv xav tau cov offsets sib txawv - stainless hlau feem ntau ntau dua li txhuas.
Xaiv Txoj Kev Zoo
MJF rau polymer brackets thiab ceev prototyping. SLM rau kev thauj khoom-cov kabmob hlau cov kabmob - qhov chaw muaj zog dua, tab sis xav tau kev pabcuam hnyav dua thiab yuav luag ib txwm tau txais txiaj ntsig los ntawm kev ua haujlwm thib ob.
Precision Ncej -Machining
Tom qab luam ntawv thiab tshem tawm kev ntxhov siab, qhov tseem ceeb yog reamed, dhuav, los yog jig-drilled los ntawm ib tug ntau datum - tig ib tug li - ua lub qhov rau hauv ib tug haumxeeb, los ua ke-npaj feature.
Cov txiaj ntsig zoo tom qab kev tshaj tawm -machining:
Qhov taub:± 0.01-0.03 hli
Qhov sib nrug (ntau tshaj 100-200 mm):± 0.02-0.05 hli
Roundness thiab ua tiav npaj rau kev sib dhos ncaj nraim
Case Study - Tswj Qhov Ncauj ntawm Cov Khoom Muag
Case Study
Tsis ntev los no stainless- steel mounting bracket txiav txim yuav tsum tau 6.0 hli H7 qhov thiab nruab nrab - mus rau -center spacing nyob rau hauv ± 0.05 mm nyob rau hauv ib tug 120 mm ncua. Raws li - tsim SLM tuaj yeem ua tsis tau raws li kev hu - tawm. Pab neeg no siv peb kauj ruam: tsim kev them nyiaj ntxiv rau kev tsim kho kom zoo; SLM luam ntawv ua raws li kev ntxhov siab{11}}kev kho cua sov; thiab CNC reaming ntawm txhua qhov tseem ceeb nyob rau hauv ib tug tshwj xeeb fixture, ces tag nrho CMM pov thawj.
Qhov kawg CMM cov ntaub ntawv qhia txoj kab uas hla variation sab hauv± 0.02 hlithiab sib nrug hauv± 0.04 hli. Cov brackets sib sau ua ke yam tsis muaj zog lossis shimming. Thawj- tsab ntawv pom zoo tau hloov mus rau qhov tsim khoom yam tsis muaj kev kho ntxiv ntxiv.
Kev Tswj Xyuas Zoo Ua Ntej Shipping
Txhua daim ntawv ua raws li cov ntaub ntawv ua ntu zus:
Daim ntawv tshaj tawm kev soj ntsuam tag nrho xa nrog cov khoom, muab kev taug qab los ntawm cov hmoov ntau mus rau qhov kawg ntsuas.
Cov lus nug nquag
Q: Dab tsi kam rau ua hlau 3D luam ntawv ua tiav ntawm lub qhov taub?
A: Raws li - ua SLM feem ntau tsaws ntawm ± 0.1 thiab ± 0.3 hli. Tom qab precision CNC reaming tib lub qhov tuav ± 0.01-0.05 hli.
Q: Puas yog 3D luam ntawv brackets xav tau tshaj tawm -machining rau qhov raug?
A: Thaum kos duab hu rau H7 lossis nruj dua, lossis thaum sib nrug yuav tsum nyob hauv ± 0.05 hli, yog. Tshaj tawm -kev ua haujlwm rau 3D luam tawm qhov yog tus qauv rau cov khoom siv kho tshuab kom raug.
Q: Qhov twg yog qhov tseeb dua rau qhov - MJF lossis SLM?
A: Muaj MJF Printing feem ntau qhia tau tias zoo dua li - ua kom zoo sib xws rau cov khoom siv polymer. Rau cov hlau brackets uas yuav tsum nqa load, SLM ntxiv rau CNC reaming muab qhov kev sib tw zaum kawg.
Q: Puas yog qhov sib nrug ntawm qhov sib txawv ntawm ntau qhov sib npaug?
A: Yog lawm, thaum tsim kev taw qhia, cov nqi them nyiaj, thiab cov ncej -machining fixture tseem zoo li qub. CMM tshuaj xyuas ntawm txhua pawg paub meej tias qhov sib txawv nyob hauv qhov pom zoo txwv.
Q: Kuv yuav ua li cas thiaj nrhiav tau lub chaw tsim khoom 3D luam ntawv bracket txhim khu kev qha?
A: Saib rau lub Hoobkas 3D tshuab luam ntawv hlau uas sib tham txog kev tsim cov nyiaj qhib qhib, ua kom CNC rov qab nyob rau hauv - tsev, thiab muab CMM cov lus ceeb toom nrog txhua qhov khoom xa tuaj. Cov ntaub ntawv ntshiab cov txheej txheem thiab kev paub nrog cov lag luam wholesale 3D luam ntawv hlau qhov chaw yog cov cim muaj zog ntawm kev ntseeg tau.
