Dab tsi yog qhov txawv ntawm hlau 3D luam ntawv thiab tsoos CNC machining hauv pwm tsim?

Ib, Technical hauv paus ntsiab lus: kev hloov pauv hauv kev tsim khoom ntxiv thiab rho tawm
Hlau 3D luam ntawv siv "txheej los ntawm txheej stacking" txoj kev ntawm kev tsim khoom ntxiv. Nws melts hlau hmoov, zoo li titanium alloy los yog cam khwb cia hlau, siv lub laser lossis electron beam thiab tom qab ntawd tsim cov duab geometric nyuaj ncaj qha los ntawm peb -dimensional digital qauv. Nws cov txiaj ntsig tseem ceeb yog tias nws tau hla cov teeb meem nrog cov tsoos machining uas ua rau nws nyuaj rau cov cuab yeej thiab siv clamps. Nws tseem tuaj yeem ua qhov kev tsim kho topology, suav nrog hollowing hauv sab hauv, sau rau hauv cov lattice, thiab ua cov dej txias uas haum. Piv txwv li, Zhongrui Technology tau ua kev cai txhaj tshuaj pwm rau kev lag luam tsheb. Cov ntawv ntxig no tau nce qhov adhesion ntawm cov dej txias hauv Circuit Court thiab cov khoom nto rau 95% los ntawm 3D luam ntawv, txiav lub voj voog txhaj tshuaj molding los ntawm 42%, thiab txiav cov khoom warpage tus nqi los ntawm 67%.
Hauv kev tsim cov khoom tsim tawm, cov tsoos CNC machining ua haujlwm los ntawm "tshem cov khoom." Nws siv cov cuab yeej txuas txuas ntawm ntau lub axes los txiav, zeb, laum, thiab ua lwm yam rau hlau billets. Nws cov thev naus laus zis kom loj hlob tau pom los ntawm nws lub peev xwm los tswj qhov tseeb ntawm qib micrometer (± 0.005mm) thiab smoothness ntawm qhov chaw (Ra0.8 μ m). Qhov no ua rau nws zoo meej rau kev ua haujlwm siab - cov khoom muaj zog nrog cov ntawv tsis tu ncua. Piv txwv li, ceramic carving thiab milling tshuab los ntawm Xintenghui CNC tuaj yeem khaws cov npoo tawg ntawm cov pwm pwm hauv qab 0.3% los ntawm kev siv cov txheej txheem tshwj xeeb thiab kev sib tsoo tshuab. Qhov no ua tau raws li cov kev cai nruj ntawm cov khoom ntim semiconductor rau pwm hnav tsis kam.
2, Daim ntawv thov scenario: Cov kab ntawm cov kev tsim kho nyuaj thiab ntau lawm
Kev siv kev sib tsoo hauv kev tsim cov txheej txheem nyuaj
Hlau 3D luam ntawv muaj qhov cuam tshuam loj rau pwm ua hauv peb qhov chaw tseem ceeb:
Zoo li nram qab no txias system: tsoos pwm txias dej raws yog txwv los ntawm cov txheej txheem drilling, uas ua rau nws nyuaj kom tau ib tug zoo meej haum nrog cov khoom contour. Los ntawm kev ua cov kua dej dynamics, 3D tshuab luam ntawv txhim kho qhov sib xws ntawm pwm kub teb los ntawm ntau tshaj 50%. Ib lub tuam txhab uas ua rau cov khoom siv hauv tsev siv cov txheej txheem no, thiab cov txiaj ntsig ntawm kev txhaj tshuaj molding cua txias plhaub tau los ntawm 89% mus rau 98%. Kev txuag nyiaj txhua xyoo ntawm lub zog rau ib txheej pwm yog ntau tshaj 120000 yuan.
Kev tsim kho lub teeb: Los ntawm optimizing lub topology, 30% mus rau 60% ntawm non-load- cov ntaub ntawv bearing raug tshem tawm, thiab qhov hnyav ntawm 3D- cov pwm luam tawm yog txo los ntawm 45% piv rau cov qauv tsim, thaum ua kom lub zog ntawm cov qauv. Lub zog tshiab lub tsheb roj teeb pob bracket ua los ntawm 3D- luam tawm aluminium alloy lub luag haujlwm tau muaj sia nyob 150% dhau qhov kev sim, poob 38% ntawm nws qhov hnyav, thiab tau txais 8% ntawm nws qhov ntau.
Kev sib xyaw molding ntawm cov khoom tsis yooj yim: Hauv cov txheej txheem ib txwm muaj, suav nrog cov roj hmab log pwm pwm qauv thaiv thiab cov khau ib leeg qauv pwm, cov khoom yuav tsum tau ua tiav thiab muab tso ua ke sib cais. 3D luam ntawv tuaj yeem ua rau tag nrho cov pwm thiab tshem tawm qhov yuam kev hauv kev sib dhos. Cov tshuab no tau siv hauv lub tuam txhab log tsheb, thiab lub sijhawm nws siv los ua pwm mus los ntawm 45 hnub mus rau 12 hnub, nrog cov qauv raug ntawm 0.02 hli.
3, Lub ntsiab kom zoo dua ntawm cov khoom loj
Qhov tseeb tias CNC machining tsis tuaj yeem hloov pauv hauv pwm ua yog qhia los ntawm:
Cov khoom siv hloov tau: Nws tuaj yeem ua haujlwm nrog cov ntaub ntawv uas nyuaj heev, xws li quenched steel thiab hard alloys (HRC55 lossis siab dua), uas yog qhov tuag-casting pwm yuav tsum tau ua. Ib qho kev tuag tshwj xeeb-casting facility ntiav CNC-processed magnesium alloy tuag-casting pwm uas kav ntev txog 200,000 zaug, uas yog peb zaug ntev dua 3D-cov pwm luam tawm.
Kev ua tau zoo ntawm qhov chaw: Daim iav- theem nto (Ra0.2 μ m) tuaj yeem ua tiav nrog kev tshaj tawm - cov txheej txheem ua tiav nrog rau kev txiav milling thiab polishing. Qhov no ua tau raws li cov qauv kev nyiam huv rau cov pwm kho qhov muag thiab cov khoom ntim pwm. Lub tuam txhab ntim tshuaj pleev ib ce siv CNC- ua tiav PET lub raj mis preform pwm, uas ua rau cov khoom lag luam pob tshab (92%) thiab txiav pov tseg (0.5%).
Batch kev lag luam: Rau pwm uas ua ntau tshaj 5000 daim ib xyoos, CNC machining nqi 60% mus rau 70% tsawg dua ib daim dua 3D luam ntawv. Ib qho khoom siv tsheb thauj khoom siv CNC loj tsim rau lawv cov pwm pwm. Tus nqi ntawm ib lub pwm yog khaws cia rau 800,000 yuan, whereas tus nqi ntawm 3D luam ntawv yog 1.2 lab yuan.
4, Tus Qauv ntawm Tus Nqi: Ib qho kev ua si ntawm qhov sib npaug ntawm qhov nrawm thiab qhov tseeb
1. Cov nqi ntawm cov khoom siv thiab cov khoom siv
3D luam ntawv nrog hlau: Muaj- cov cuab yeej qib feem ntau raug nqi ntawm 2 txog 8 lab yuan, thiab titanium alloy hmoov raug nqi ntawm 800 thiab 1200 yuan ib kilogram. Kev siv cov khoom siv, ntawm qhov tod tes, yog siab li 90%, uas yog 40 feem pua ​​​​cov ntsiab lus ntau dua li CNC machining. Ib lub tuam txhab aviation tshwj xeeb tau siv 3D luam ntawv los ua cov cav ntoo, uas tau txiav cov nqi ntawm 35% piv rau cov tsoos casting.
CNC machining: Tsib -axis linkage machining chaw zov me nyuam raug nqi ntawm 1.5 thiab 5 lab yuan, thiab kwv yees li 15% mus rau 20% ntawm tus nqi yog rau cov cuab yeej. Ib lub Hoobkas pwm txo tus nqi ntawm ib txheej pwm los ntawm 120,000 yuan mus rau 70,000 yuan los ntawm kev ua kom zoo rau txoj kev txiav thiab siv cov hniav rov qab.
2. Lub sij hawm tus nqi 3D luam ntawv: Lub sij hawm nws yuav siv sij hawm los ua pwm nrog cov txheej txheem nyuaj yog txiav hauv ib nrab mus rau 70% piv rau cov txheej txheem ib txwm muaj. Lub tuam txhab kev kho mob tuaj yeem ua rau kev cai orthopedic implant pwm hauv tsuas yog 72 teev, uas yog 80% sai dua li 15-hnub voj voog ntawm CNC machining.
CNC machining: Pwm lub sijhawm ua haujlwm tuaj yeem raug txiav los ntawm 30% mus rau 40% los ntawm kev ua haujlwm siab -ceev txiav (HSC) thev naus laus zis. Ib qho 8000rpm spindle machining center tau pab ib qho 3C khoom pwm lag luam txiav lub sijhawm nws siv los ua lub xov tooj pwm pwm los ntawm 18 teev mus rau 11 teev.
