Mukamva 'makina olondola kwambiri', malingaliro ambiri amalumphira molunjika ku ma micron-level tolerances ndi CAD yonyezimira. Ndilo gawo la izo, zedi, koma ndi gawo lophweka. Nkhani yeniyeni imayamba mukakhala ndi gulu la Inconel 718 patebulo, kusindikiza kumayitanira ± 0.02mm, ndipo mukuyang'ana kusuntha kwamafuta, kuvala kwa zida kuyambira komaliza, komanso ngati kuzizira kozizira kumawonekera. Kusiyana komweku pakati pa zongoyerekeza ndi gawo lakuthupi - ndipamene masewerawa amaseweredwa. Sikuti kukhala ndi makina asanu olamulira; ndikudziwa zomwe makinawo adzachita nthawi ya 3 PM Lachisanu lachinyezi.
Maziko: Zimayamba ndi Kuponya
Simungathe kuyika makina olondola ndikuponya koyipa. Ndawonapo mapulojekiti ambiri akusokonekera chifukwa wina amaganiza kuti gawo la CNC litha kukonza masinthidwe oyambira kapena porosity yapansi panthaka kuchokera pazoyambira. Machining ndiye tanthauzo lomaliza, lovuta, koma kukhulupirika kwa gawo kumabadwa kale kwambiri. Ichi ndichifukwa chake kuphatikizika kwa kuponyera ndi kupanga pansi pa denga limodzi, monga ku Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), sikungothandiza chabe - ndi njira yoyendetsera bwino. Pamene gulu lomwelo lomwe limapanga gawolo limayang'aniranso nkhungu ya chipolopolo kapena njira yopangira ndalama, mumachotsa kusanjikizana konse kwa kuloza zala ndi kusatsimikizika.
Tengani ntchito yawo ndi ma aloyi opangidwa ndi nickel. Kukonza izi si nkhani yongosankha giredi yoyenera. Muyenera kumvetsetsa momwe mbewu zimayendera kuchokera pakuponya, momwe zinthu zochepetsera kupsinjika zingakhudzire mphamvu zanu zomangirira, ndi pomwe mawanga owuma amabisala. Ngati kuponya sikupangidwa ndi zotsatira kukonza mwatsatanetsatane makina mu malingaliro, mukumenya nkhondo yokwera kuchokera pa chida choyamba kukhudzana.
Ndimakumbukira chigawo cha hydraulic manifold, chitsulo chocholowana chachitsulo. Chojambulacho chinali chaukali. Choyambitsa chomwe chinapanga zoyambira sichinaphatikizidwe ndi malo ogulitsa makina. Chotsatira? Kusakhazikika kwa khoma kumbuyo kwa nkhope zosindikizira zovuta, zomwe zimatsogolera ku maloto owopsa pakumaliza. Mbali zina zidabowoka, zina zidawukhira. Kuyika kukadakongoletsedwa ndi makina omaliza opangira makina ngati chiwongolero - china chake chomwe chimaphatikiza othandizira ngati Mtengo wa QSY amachita monga mwachizolowezi-kuti ziwonongeko ndi kukonzanso zikanapewedwa pa gwero.
Njira Yachida Ndi Kukambirana, Osati Lamulo
Pulogalamu ya CAM imakupatsani njira yopangira zida. Makina amayesa kutsatira. Maonedwe opanda pake ndikuti awa ndi mapeto a nkhani. Lingaliro lachidziwitso ndiloti apa ndi pamene kukambirana kumayambira. Zoona kukonza mwatsatanetsatane makina, makamaka pazithunzi zovuta za geometri kuchokera kufupi-mawonekedwe amtundu wamtundu, njira yokonzedweratu imangokhala zolemba zoyambirira.
Muyenera kumvera kudulidwa. Phokoso, mtundu wa chip ndi mawonekedwe, kusiyanasiyana pang'ono pamawerengedwe a mita - zonsezi ndi mayankho. Pa valavu yachitsulo chosapanga dzimbiri, titha kukonza liwiro lapamwamba komanso chakudya. Koma ngati simukusintha panthawi yomwe mpheroyo imagwiritsa ntchito mtanda wamkati motsutsana ndi khoma loyera lakunja, mumacheza kapena kupatuka. Gawo la 'patsogolo' ndi gawo losinthika, lowoneka bwino, lowongolera lomwe limakhala pamwamba pa G-code. Ndi katswiri wamakina kapena wopanga mapulogalamu akudziwa kuti pagulu ili la 17-4 PH lopanda banga kuchokera pakusungunuka kwapadera, ayenera kuponya chakudya 5% m'matumba.
Apa ndipamene zaka 30 zakumbuyo zomwe QSY imatchula zimakhala zowoneka. Si zaka 30 zokha akuyendetsa makina; ndi zaka 30 akumanga laibulale maganizo mmene zipangizo cobalt-based aloyi kuti kuponya chitsulo khalidwe pansi chida. Laibulaleyo imadziwitsa zosintha zazing'ono zomwe zimalekanitsa gawo labwino ndi labwino.
Metrology: Kuyeza ndi Kudziwa (Mwinamwake)
Nayi msampha wamba: kudalira kwambiri lipoti la CMM. Mumapeza pepala loyendera nkhani yoyamba yokhala ndi zobiriwira zonse ndikuganiza kuti ndinu agolide. Koma kodi kutentha kwa gawolo kunali kotani poyesedwa? Kodi zidamu zidatsukidwa pazotsalira zonse zoziziritsa kukhosi ndi ma micro-burrs? Kodi kukanikizira panthawi yoyezera kunali kofanana bwino ndi kukanikizira panthawi yopanga makina? Ngati sichoncho, lipoti lokongola limenelo ndi ntchito yopeka.
Mu ntchito yolondola, kuyeza ndi luso palokha. Nthawi zambiri timagwiritsa ntchito njira zosiyanasiyana. CMM ya kulolerana konse kwa geometric, inde. Koma pazisindikizo zovuta kwambiri, mwina profilometer yapamwamba. Kwa ma diameter akuya, ang'onoang'ono, chowongolera mpweya kapena ngakhale pini yapadera. Cholinga ndi kulumikizana - kuwonetsetsa kuti miyeso yanu yonse ikugwirizana. Ndakhala ndi nthawi pomwe CMM idati bore ndikulolera, koma plug ya master plug siyenera. Wolakwa? Chojambula chowoneka bwino kapena choyimbira chomwe sampuli zamtambo za CMM zidaphonya. Malingaliro 'otsogola' ndi amodzi okayikakayika pazambiri zanu.
Kwa kampani yomwe ikugwira chilichonse kuyambira pazitsulo zazikuluzikulu zachitsulo mpaka zida zolimba za alloy turbine, malingaliro a metrology awa ayenera kukhala owopsa komanso odziwa zinthu. Kuyeza bulaketi yachitsulo sikufanana ndi kuyeza kagawo kakang'ono kakang'ono ka cobalt cobalt komwe kangathe kusinthasintha kulemera kwake pa siteji ya CMM.
Malo Apadera a Alloys: Kumene Chiphunzitso Chimakumana ndi Chida
Aliyense atha kuyang'ana mathamangitsidwe ndi ma feed omwe akulimbikitsidwa a Inconel mu bukhu. Kuwatsatira kuti apange gawo lopindulitsa ndi nkhani ina. Kukonzekera kolondola kwapatsogolo wa ma aloyi apadera monga opangidwa ndi faifi tambala kapena opangidwa ndi cobalt ndi kafukufuku wowongolera nkhanza. Mufunika kutentha kokwanira kumalo ometa ubweya kuti musunge pulasitiki yakuthupi, koma osati kwambiri kuti mugwire ntchito-kuumitsa pamwamba kuti mukhale wosanjikiza womwe ungawononge chida chotsatira.
Kusankha zida kumakhala kofunikira kwambiri. Osati ceramic kapena carbide iliyonse ingachite. Geometry ya choyikapo, chophimba, mapangidwe a chipbreaker-zonse ziyenera kukonzedwa. Kuziziritsa sikungoziziritsa; ndizopaka mafuta ndi kutulutsa chip pazovuta zomwe zimatha kupitilira 1000 psi. Kulephera mu ulalo uliwonse wa unyolowu kumatanthauza gawo lophwanyika, ndipo zida izi sizotsika mtengo. M'mphepete mwa zolakwika ndi pafupifupi ziro.
Uwu ndiye luso lofunikira kwa othandizira ngati Mtengo wa QSY. Kutchula kwawo zinthu izi sikungomveka; ndi chizindikiro kuti iwo padera mu yeniyeni makina chida kukhazikika, mkulu-anzanu coolant kachitidwe, ndipo chofunika kwambiri, kudziwa opareshoni kuthamanga gauntlet bwino. Si bizinesi yam'mbali; ndi luso lodzipereka.
Kuphatikiza: Kuchita Zosawoneka
Pomaliza, tiyeni tikambirane za flow. Mdani wamkulu wa kulondola ndi kusagwirizana, ndipo kusagwirizana nthawi zambiri kumachokera kumanja. Pamene kuponyedwa kumapangidwa mufakitale imodzi, kutumizidwa ku ina kukapanga movutikira, kenako gawo limodzi mwa magawo atatu kuti amalize, mumayambitsa zosintha pagawo lililonse. Zosiyanasiyana kutentha, mafilosofi osiyanasiyana clamping, zipangizo zosiyanasiyana mfundo.
Ntchito yophatikizika yomwe imagwira chipolopolo cha nkhungu / kuyika ndalama ndi kukonza mwatsatanetsatane makina mu kayendedwe kogwirizana kumathetsa zosinthazi. Gawolo silimazizira mpaka kudziko losadziwika pakati pa ntchito zazikulu. Gulu lomwelo laukadaulo litha kukonza zipata zoponyeramo ndi malo okwera potengera komwe zida zomaliza zidzakonzedwa, kuchepetsa kuchuluka kwa katundu ndi kupotoza. Zimalola kuti pakhale ndondomeko yeniyeni yeniyeni.
Uwu ndiye mwayi wobisika kumbuyo kwa choyimira cholunjika. Ndizochepa za makina omwewo komanso zambiri za ulusi wopanda msoko wowongolera kuchokera kuchitsulo chosungunula mpaka kutha, chigawo choyang'aniridwa. Kulondola sikungopangidwa ndi makina; zaphikidwa munjira yonse kuyambira tsiku loyamba. Mukafufuza zida zovuta, zogwira ntchito kwambiri, umwini wantchitoyo si chinthu chamtengo wapatali - nthawi zambiri ndiyo njira yokhayo yotsimikizira zotsatira zomwe zimafuna kusindikiza.
