Mukamva za 'zitsulo zomangira jakisoni', chithunzi chake nthawi zambiri chimakhala cha tizigawo ting'onoting'ono, zovuta, zokulirapo - magiya, zida zopangira opaleshoni, zida zamfuti. Ndizowona, koma ndipamenenso malingaliro olakwika amakampani amayambira. Anthu amaganiza kuti MIM ndi njira yotsika mtengo yopangira makina owoneka bwino. Zoona zake, kuchita bwino kumatengera kapangidwe ka kupanga koyambira koyamba, zomwe mumangophunzira mutawona magulu angapo okwera mtengo akusintha kukhala zidutswa. Si njira yamatsenga; ndi unyolo wodziletsa wa feedstock, kuumba, debinding, ndi sintering, kumene ulalo uliwonse uyenera kulinganizidwa bwino kwa zinthu. Konzani kuti mpweya wotentha ukhale wolakwika pagawo lachitsulo chosapanga dzimbiri, ndipo mukuyang'ana kujambula kwa kaboni ndi kulephera kwa dzimbiri. Ine ndaziwona izo zikuchitika.
Chiyambi cha MIM: Ndi Njira, Osati Chogulitsa Chokha
Tiyeni tifotokoze zenizeni. Chokopacho ndi chopangidwa ndi net-shape kapena pafupi ndi net-shape. Mutha kupeza mafomu osatheka ndi kuyika ndalama kapena okwera mtengo kwambiri ndi makina a CNC. Koma 'near-net-shape' ndilo liwu logwira ntchito. Pali kuchepa-kungodziwiratu koma osati nthawi zonse mofanana. Ngati mapangidwe anu ali ndi zigawo zokhuthala komanso zoonda kuchokera pakhoma mpaka khoma, mukupempha kupotoza panthawi ya sintering. Nthawi ina tinkapanga chojambula cha makina otsekera, mbali yomwe ili ndi latch yofewa yophatikizidwa ndi maziko olemera kwambiri. Kuthamanga koyamba kunatuluka m'ng'anjo yokhota pang'ono, zokwanira kuti latch imangirire. Kukonza sikunali mu magawo a MIM okha; kunali kukonzanso kogwirizana kuti awonjezere nthiti yaying'ono, yosakhalitsa yothandizira mu chikhalidwe chobiriwira chomwe chinachotsedwa pambuyo pake mu makina achiwiri. Ndilo dziko lenileni.
Kusankha kwakuthupi ndi chirombo china. Zodziwika bwino monga 17-4PH zosapanga dzimbiri kapena zitsulo zotsika ndi njira zopondedwa bwino. Koma kasitomala akabwera kudzapempha a kuumba jekeseni wachitsulo gawo mu superalloy yozikidwa pa faifi pakugwiritsa ntchito kwamlengalenga kwanthawi yayitali, masewera onse amasintha. Mtengo wa ufa umakwera kwambiri, zofunikira za ng'anjo yoyaka moto zimakhala zochulukira (vacuum yayikulu, mafunde olondola a kutentha), ndipo malire a zolakwika amasowa. Mawonekedwe amakina ndiabwino kwambiri ngati mungawakhomerere, koma mtengo wa chitukuko ndi wokulirapo. Iyi sibizinesi yongotengerani inu mu ola limodzi.
Apa ndipamene kukhala ndi bwenzi lomwe lili ndi zinthu zakuya zazitsulo zazitsulo. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd. kumabweretsa malingaliro osiyana. Pazaka zopitilira 30 popanga nkhungu, kupanga ndalama, ndi makina a CNC, amamvetsetsa machitidwe achitsulo - kusintha kwa gawo, kapangidwe ka tirigu, kupsinjika - kuchokera kumakona angapo. Pamene olimba wotero akuwonjezera MIM luso, iwo samangogula makina; iwo akugwiritsa ntchito zaka makumi a sayansi yakuthupi. Kuwona mbiri yawo pa tsngtaocnc.com, mukuwona ntchito yawo ndi cobalt ndi nickel alloys popanga ndalama. Ukadaulo umenewo umamasulira mwachindunji kuyang'anira zida zachinyengo mu ng'anjo ya MIM, kuyembekezera momwe zidzachulukira komanso zinthu zomaliza zomwe zingayembekezere. Ndi mwayi waukulu kuposa shopu yomwe imangochita MIM.
Kumene MIM Ikwanira (ndipo Pomwe Sili)
Ndiye, malo okoma ndi chiyani zitsulo jekeseni akamaumba mankhwala? Medical ndi chachikulu. Biopsy forceps nsagwada, mabulaketi orthodontic, opaleshoni stapler zigawo zikuluzikulu. Ma voliyumu amalungamitsa zida, zovuta zake ndizokwera, ndipo zinthu (nthawi zambiri 316L zosapanga dzimbiri) ndizokhazikika za MIM. Kumaliza kwapamwamba kochokera ku sintering ndikokwanira kugwiritsa ntchito ma biocompatible ambiri, nthawi zina kumangofunika kutsika pang'ono kapena kutsika.
Koma apa pali vuto lomwe silinagwirizane. Wofuna chithandizo ankafuna bulaketi yaikulu, yofanana ndi dzanja. Ma geometry anali abwino, koma chofunikira kwambiri chinali kulimba kwa njira inayake. Ngakhale MIM imatha kukhala ndi mphamvu zolimba, mawonekedwe a isotropic a gawo lopindika (katundu kukhala wofanana mbali zonse) sangafanane ndi momwe mbewu zimayendera zomwe mumapeza kuchokera pakupanga kufunikira kolimba. Tidayenera kulimbikitsa motsutsana ndi MIM ndikuwalozera ku njira yopangira. Kudziwa nthawi yoti musagwiritse ntchito zipangizo zamakono n'kofunika mofanana ndi kudziwa nthawi yoti mugwiritse ntchito.
Masensa agalimoto ndi malo ena omwe akukula. Nyumba zokhala ndi masensa, magiya ang'onoang'ono a ma actuators, magawo ojambulira mafuta. Kusintha kwa magalimoto amagetsi kukusintha kusakanikirana kwa gawo, koma kufunikira kwa zigawo zing'onozing'ono zazitsulo zolondola pamapampu, masensa, ndi zolumikizira zimakhalabe. Kupanikizika pano kuli pamtengo komanso kusasinthika pakati pa magawo mamiliyoni ambiri. Chiwopsezo chomwe chili chovomerezeka pagawo locheperako lazamlengalenga ndi tsoka pano. Apa ndipamene kuwongolera ndondomeko ndi kuyang'anira ndondomeko ya ziwerengero mu mzere wa MIM kumakhala kosakanthika.
The Handoff: Second Operations ndi Real-World Integration
Pafupifupi palibe gawo la MIM lomwe latha pambuyo poimba. Ambiri amafunikira maopaleshoni achiwiri. Ichi ndi gawo lofunikira lomwe ambiri amanyalanyaza pamtengo woyambira. Mungafunike makina a CNC kuti mugunde kulolerana kwa ± 0.01mm pabowo linalake, kapena kuti mupange chinthu chomwe sichingapangidwe, ngati ngodya yakuthwa yamkati. Mungafunike kugaya, kutentha kutentha, kapena plating.
Uwu ndiye phindu lobisika la wopanga ophatikizika. Tengani chitsanzo cha QSY kachiwiri. Ngati gawo la sintered MIM likutuluka ndipo likufunika kukhazikika bwino kwa CNC mphero kapena dzenje loponyedwa, amatha kuyisuntha molunjika kugawo lawo la makina. Palibe kuchedwa kwa kutumiza, palibe kulumikizana pakati pa injiniya wa MIM ndi katswiri wamakina pazapadera za gawolo (monga malo ake opindika pang'ono poyerekeza ndi chitsulo chopangidwa). Mayankho afupipafupi ndi olimba. Atha kunena kuti, Gawo la MIM losapanga dzimbiri lidawumitsidwa pang'ono pambuyo poti sintering, ndiye tisintha liwiro la chida ndikudyetsa CNC. Kuphatikiza kumeneko kumapulumutsa nthawi, mtengo, ndi mutu.
Nkhani ina yeniyeni ndi kufufuza khalidwe. Kodi mumawona bwanji kuchuluka kwamkati kwa gawo laling'ono la MIM? Kuyesa kowononga ndi muyezo wagolide - kudula, kupukuta, kuyang'ana pa microstructure pansi pa microscope. Kuti mupange, mumadalira kuwongolera: kutsatira mosamalitsa kutentha kwa sintering, nthawi, ndi mlengalenga pagulu lililonse. Koma kukhala ndi kuthekera kochita kusanthula kwazitsulo mkati mwanyumba, komwe kampani yanthawi yayitali yopangira makina ingakhale nayo, ndi chinthu chofunikira kwambiri pakutsimikizira zolemba zoyamba ndikuthetsa mavuto.
Mtengo wa Equation: Zida, Volume, ndi Invisible Factors
Lamulo lachikale ndikuti MIM imakhala yotsika mtengo pafupifupi magawo 10,000+ pachaka, chifukwa cha mtengo wa zida. Ndi poyambira bwino, koma ndizosavuta. Equation yeniyeni imaphatikizapo zovuta zina. Ngati gawo lingafunike makhazikitsidwe 5 osiyanasiyana a CNC ndi zinyalala za 80%, MIM ikhoza kukhala yotsika mtengo pa zidutswa 5,000. Zida za MIM zili ngati kuumba jekeseni wa pulasitiki-zovuta, zolimba zachitsulo. Ndi mtengo wodzaza kutsogolo.
Koma ndalama zosaoneka zili mu chitukuko ndi ziyeneretso. Mudutsamo kangapo: chida chotsimikizira kapangidwe kake, chida choyambirira chopangira, ndiye nthawi zambiri kukonza bwino chidacho pambuyo poyeserera koyambirira kuti muwerenge za kuchepa. Kuzungulira kulikonse kumatenga nthawi ndi ndalama. Pa gawo lofunikira, ndiye kuti muyenera kuyenerera zonse - osati gawo lomaliza. Makasitomala anu (makamaka azachipatala kapena zamagalimoto) adzafuna kuwunika omwe akukupatsirani chakudya, zipika zanu zamoto, mapulani anu owongolera. Ichi ndi ntchito ya miyezi yambiri.
Kumene makampani omwe ali ndi maziko opangira zinthu ngati QSY amatha kuchepetsa izi ndi kudzera mu chidziwitso chofananira. Zomwe adakumana nazo pokwaniritsa njira yopangira ndalama kuti apange tsamba la turbine la nickel-based alloy turbine turbine imakhudzanso kulimba kofananako - kuwongolera kusungunuka, nkhungu, ndi kulimba. Chilango chotsatirachi chimamasulira mwachindunji kuyenerera mzere wa MIM. Amamvetsetsa zolemba, kutsatiridwa, ndi kutsimikizika kwa njira zomwe zimafunikira kuti azigwira ntchito zamafakitale oyendetsedwa, komwe ndi komwe ntchito zambiri za MIM zokhala ndi malire abwino zimapezeka.
Kuyang'ana M'tsogolo: Osati Kusintha, Njira Yamphamvu
MIM sidzalowa m'malo opangira ndalama pazinthu zazikulu, zokhala ndi mipanda yopyapyala ngati masamba a turbine. Izo sizidzalowa m'malo CNC Machining kwa prototypes amodzi kapena mbali ndi tolerances zolimba kwambiri mbali iliyonse. Ndipo sizingalowe m'malo mwa masitampu osavuta, ochapira.
Zomwe imachita ndikukhala ndi kagawo kakang'ono kamene kakukula: zovuta kwambiri, zazitsulo zazing'ono mpaka zapakati pamavoliyumu okulirapo. Tsogolo liri pakulisakaniza - kugwiritsa ntchito MIM kupanga 95% ya mawonekedwe a gawolo, kenako kugwiritsa ntchito makina olondola kapena makina ang'onoang'ono kuti atsirize zofunikira. Ndikupanga zakudya zatsopano zopangira zinthu monga titaniyamu, zomwe zimadziwikabe bwino mu MIM chifukwa chakuchitanso kwake.
Pamapeto pake, zopambana zitsulo jekeseni akamaumba mankhwala zimachokera ku ukwati wa cholinga cha mapangidwe ndi luso la ndondomeko. Zimafunika kuti wopanga aziganiza zakuyenda kwa ufa, kuchotsa zomangira, ndi kuchepera koyendetsedwa. Ndipo pamafunika wopanga kukhala ndi zambiri kuposa kungosindikiza kwa MIM; amafunikira chidziwitso chakuya chazitsulo, kuwongolera kolimba kwa njira, ndipo nthawi zambiri, kuthekera kochita maopaleshoni achiwiri ofunikira mosasunthika. Ndiko kusiyana pakati pa ogulitsa ndi bwenzi. Mukawunika wogulitsa, yang'anani kupyola bukhu lawo la MIM. Yang'anani pa chilengedwe chawo chonse ndi kupanga zachilengedwe-monga zaka makumi ambiri akuponya ndi kukonza kuseri kwa kampani monga QSY-chifukwa chidziwitso choyambira ndi chomwe chimatsimikizira kuti gawo lanu silimangotuluka mu nkhungu, koma limagwira ntchito modalirika.
