Pamene anthu kulankhula za kuponya molondola, chinthu choyamba chomwe chimabwera m'maganizo nthawi zambiri ndi kulolerana pa chojambula, mwinamwake chinachake chonga ± 0.5mm. Ndilo gawo lake, zedi, koma ngati mwakhalapo nthawi yeniyeni pansi pa maziko, mukudziwa kuti ndi malo chabe. Kulondola kwenikweni pakuyimba ndi chinthu chosokonekera, chokhazikika - chikukhudza kukhazikika kwapang'onopang'ono, zedi, komanso za kukhulupirika kwapamtunda, kumveka kwamkati, ndi momwe gawolo limakhalira litagwedezeka ndikukhazikika. Makasitomala ambiri, makamaka omwe angoyamba kumene kutsatsa, amakhazikika pa nambala imodzi. Adzafuna kulolerana molimba ngati-cast popanda kuzindikira kuti woyendetsa mtengo si nkhungu chabe, koma chirichonse kuchokera ku khalidwe la alloy shrinkage mpaka momwe mumakonzekera dongosolo la gating. Ndawonapo ma projekiti akupita chammbali chifukwa cha kutha. Kukambirana kwenikweni kuyenera kuyamba ndi ntchito: kodi gawoli limachita chiyani, kulondola kwake kuli ndi phindu pati, ndipo ndi kuti komwe tingalole kusintha kwazinthu kuti zisawonongeke? Ndipamene zinachitikira zimabwera.
The Shell Mold Balancing Act
Kumalo athu ogulitsira, kuponya nkhungu ndi njira yofunika kwambiri, ndipo ndipamene nkhondo yolondola kwambiri imamenyedwa. Kukongola kwake ndikumapeto kwabwino kwambiri komanso kulondola kwabwino komwe mungathe kutuluka mu nkhungu. Koma kulemekeza sikokwanira nthawi zonse. Kulondola apa ndi ntchito yolunjika ya chitsanzo. Ngati ukadaulo wanu suli wangwiro, kuwerengera mitengo yocheperako mpaka gawo la peresenti, mukungobwereza zolakwika. Timagwiritsa ntchito mapangidwe apamwamba a epoxy kapena zitsulo, ndipo kukonza kwawo ndikofunikira. Chip chaching'ono kapena zotsalira zotulutsa zimakopera pa chipolopolo chilichonse chomwe mumapanga.
Ndiye pali chipolopolo chomwe. Makulidwe ake ndi kufanana kwake ndi kwakukulu. Malo opyapyala amatha kuyambitsa kuyaka kapena kuphulika, kupha kulondola kwa mawonekedwe anu. Timayang'anira izi kudzera m'miyezo yoviika ndi kuyika - kukhuthala kwa slurry, kukula kwa njere yamchenga, nthawi yowuma pakati pa malaya. Zimamveka ngati njira, koma m'malo osayendetsedwa ndi nyengo (omwe maziko ambiri sali), tsiku lachinyontho limatha kutaya nthawi yanu yowumitsa, zomwe zimapangitsa kuti chipolopolocho chikhale chofooka, chosakhazikika. Mumaphunzira kuwerenga mpweya, osati buku lokha. Cholinga chake ndi chipolopolo chomwe chimakhala champhamvu kwambiri kuti chizitha kupirira chitsulo chosungunuka popanda kupotoza, koma osati chokhuthala kwambiri chomwe chimayambitsa kuzizira kwambiri kapena kupangitsa kuti pakhale nkhawa. Ndi kusinthasintha kosalekeza.
Ndimakumbukira gulu la matupi a valve mu zitsulo zosapanga dzimbiri zosapanga dzimbiri zaka zingapo zapitazo. Zolembazo zinapangitsa kuti pakhale kulekerera kolimba. Zipolopolozo zinali zangwiro, aloyiyo inali yoti afotokoze, koma ma bore omwe amaponyedwa nthawi zonse amakhala pamtunda wotsika. Nkhani yake? Posachedwapa tidasinthiratu kusakaniza kwa mchenga wa zircon kumakhoti oyambira. Zinali ndi matenthedwe osiyana pang'ono, omwe adasintha kutsogolo kolimba kuti akhudze kuchepa kwa gawo lofunikiralo. Kukonza sikunali kupanga makina ochulukirapo - kunali kusintha makulidwe amtundu wapateni ndi magawo khumi pang'ono kuti athe kubweza chipolopolo chatsopanocho. Ndizo kuponya molondola: kuyang'anira mndandanda wa zosinthika, osati chimodzi chokha.
Kuponya Ndalama: Kuthamangitsa Nthano ya Net-Shape
Kuyika ndalama kumapangitsa kuti zilembo zolondola ziziwoneka mozungulira, nthawi zambiri zimagulitsidwa ngati njira yofanana ndi ukonde. Ndipo zikhoza kukhala, kwa ma geometries ena. Koma mawonekedwe a ukonde ndi nyimbo ya siren. Njira yobaya phula imayambitsa mitundu yakeyake-kuthamanga kwa jekeseni, kutentha, ndi nthawi yozizirira zonse zimakhudza kukula kwa phula. Kusintha kwa 0.1% pakukula kwa sera kumakulitsidwa kudzera mu chigoba cha ceramic ndi kutsanulira komaliza kwachitsulo. Pazinthu zambiri zopangira ndalama zamalonda, mukuyang'anabe ndalama zogulira makina, zocheperako.
Kumene kumawala bwino ndi mawonekedwe amkati ndi ma contour ovuta omwe ndi okwera mtengo kwambiri pamakina. Ganizirani za ma impellers kapena ma turbine masamba okhala ndi njira zoziziritsira mkati. The kuponya molondola apa ndi za kulanda geometry mokhulupirika. Chovuta ndikuletsa kusintha kwa ceramic pachimake kapena kupotoza panthawi ya dewaxing ndi kuwombera. Nthawi zambiri timapanga mtengo wophatikizira sera ndi potchingira kuti azichirikiza ndikuthandizira ma cores osalimba. Ndi chododometsa. Chithunzi cholephera chimatanthawuza kuponyedwa komwe ndime yamkati ili kutali, zomwe zimapangitsa kuti gawolo likhale lopanda ntchito ngakhale kunja kuli koyenera.
Tinagwira ntchito yopangira zida zachipatala, gawo la aloyi ya cobalt-chrome yokhala ndi lattice. Kuchikonza kunali kosowa. Chofunikira cholondola chinali chocheperako pamlingo winawake wa mzere komanso zambiri za kusasinthika kwa ma diameter a lattice strut ndi porosity ya pamwamba. Tinadutsa maphikidwe ambiri a sera ndi zipolopolo. Kupambanako kudabwera chifukwa chosintha kutentha kwa nkhungu musanathire. Kutentha kwambiri, ndipo chitsulocho chingawononge tsatanetsatane wa ceramic; kuzizira kwambiri, ndipo chitsulo sichikanadzaza zigawo zoonda kwathunthu. Kulondola kumatanthauzidwa ndikubwerezabwereza magawo mazana, osati kungogunda nambala imodzi.
Zofunika ndi Uthenga
Simungathe kunena zolondola popanda kunena za chitsulo chokha. Apa ndipamene ma generic foundries ambiri amagunda khoma. Ku QSY, kugwira ntchito ndi chilichonse kuyambira chitsulo chopangidwa ndi nickel kumatanthauza kuti muyenera kukonzanso zomwe mukuyembekezera pa ntchito iliyonse. Iron imvi imakhala ndi madzi abwino komanso kutsika kodziwikiratu, pafupifupi 1%. Ndi kukhululuka ndithu. Koma sinthani ku chitsulo chosapanga dzimbiri chowumitsa mpweya kapena chitsulo cha nickel, ndipo masewera onse amasintha.
Ma aloyi apaderawa ali ndi mawonekedwe osiyanasiyana opangira matenthedwe. Ena amakonda kung'ambika ngati nkhunguyo ndi yolimba kwambiri, zomwe zimakupangitsani kugwiritsa ntchito nkhungu yosakhazikika - kusinthanitsa pompopompo. Zina, monga ma bronzes ena a aluminiyamu, amakhala ndi nthawi yayitali yolimba, zomwe zimapangitsa kuti azitha kugwidwa ndi micro-porosity, yomwe imatha kuwonekera pa X-ray koma imatha kukhudza momwe gawolo likugwirira ntchito pokakamizidwa. Maonekedwe anu okwera ndi okwera amakhala ofunikira kwambiri pakulondola, osati kungopewa ming'alu, koma kuwonetsetsa kukhazikika komwe kumachepetsa kupsinjika kwamkati ndi kupotoza. Gawo lomwe limazungulira pambuyo pochiza kutentha si gawo lenileni, ngakhale litayezedwa bwino lomwe limakhala lobiriwira.
Tinaphunzira izi movutikira ndi mndandanda wa nyumba zazikulu zopopera mu aloyi ya nickel-chromium. Zolemba zoyamba zidadutsa macheke amtundu uliwonse. Koma pambuyo njira kutentha mankhwala, iwo ankapotoza ngati nthochi. Vutoli linali kupsinjika kotsalira komwe kumatsekeredwa muzoponya kuchokera ku kuzizira kosagwirizana. Tinayenera kubwerera ndikukonzanso zokwera ndikuwonjezera zipsepse zoziziritsa ku nkhungu kuti tilimbikitse kulimba kofanana. Kulondola kwake kunayenera kupangidwa ndi kasamalidwe ka matenthedwe, osati pakhungu lokha.
Pomwe CNC Machining Imalowa (Si Crutch)
Anthu ambiri amaganiza za CNC Machining ngati sitepe yoyeretsa kuti mukwaniritse kulondola komaliza, ndipo mpaka pamenepo, ndizowona. Koma ngati mukuigwiritsa ntchito ngati njira yopulumutsira, mitsinje yanu imasanduka nthunzi. Cholinga chake ndi kupereka kuponya komwe kuli kokwanira kuti makina azigwira bwino ntchito. Izi zikutanthawuza kuti makulidwe a khoma losasinthika, ndalama zolozera katundu, ndi zolakwika zochepa zobisika zomwe zingathyole chida.
Makina athu amkati ku QSY amapanga malingaliro olimba. Opanga makina amatiuza ndendende komwe masheya amasiyanasiyana, komwe kuli mawanga olimba, kapena ngati kuponya kumatuluka panthawi yothina. Intel ija imabwereranso ku foundry. Mwachitsanzo, ngati nthawi zonse tikuwona 0.3mm yowonjezera pankhope imodzi ya flange, tikhoza kusintha ndondomeko kapena ndondomeko kuti tibwezeretse. Synergy iyi ndi yomwe imatilola kulonjeza zodalirika kuponya molondola. Simatsenga; ndi kulankhulana.
Ndimakumbukira ntchito yapamwamba kwambiri yopangira mabulaketi amagalimoto. Kulekerera kwapang'onopang'ono pazitali za bwana wa bawuti kunali m'malire pamzere wamakina wamakasitomala. Iwo ankafunika kusasinthasintha kwambiri. Posanthula magawo mazana angapo opangidwa ndi makina, tazindikira kulumikizana pakati pa kutentha kwa kuthirira ndi kutalika kwa bwana womaliza pambuyo popanga. Kutentha kwapamwamba pang'ono kunapangitsa kuti pakhale kuchepa pang'ono mu gawo lakutalilo, lolemeralo. Tinalimitsa zenera lathu lowongolera kutentha, ndipo vutolo lidatha. Kulondola kudakwaniritsidwa poyang'anira kusintha kwadongosolo komwe sitinaganizirepo kofunikira pamlingowo.
Kugwirizana Kwambiri Padziko Lonse ndi Kupereka Mtengo
Kotero, pambuyo pa zonsezi, ndi chiyani kuponya molondola? M'zochita, nthawi zambiri ndi luso la zotheka mkati mwazowona zachuma. Ndiko kudziwa nthawi yoti mutchule CT scan ya gawo lofunikira kwambiri lazamlengalenga motsutsana ndi pomwe UT yokhazikika ndi cheke cham'mbali chikukwanira ma hydraulic manifold. Ndikumvetsetsa kuti 0.25mm pamwamba roughness (Ra) ikhoza kutheka ngati ikuponyedwa ndi kuponyedwa kwa ndalama, koma pa gawo lalikulu la nkhungu, kufotokoza 1.6mm Ra ndikukonzekera kuphatikizika kwachangu ndikwanzeru komanso kotchipa.
Mtengo womwe timapereka kumakampani ngati Qingdao Qiangsenyuan Technology sikungopanga mawonekedwe. Ndi kutsogolera kasitomala kudzera mu malonda awa. Mutha kupeza njira yathu ndi luso lathu mwatsatanetsatane https://www.tsingtaocnc.com. Pazaka zopitilira makumi atatu pakuponya ndi kupanga, ukatswiri weniweni uli pakuchotsa mavuto. Ndikuyang'ana chojambulira ndikunena kuti, Radiyo ndi yakuthwa kwambiri pa aloyi yomwe mwasankha - ipangitsa kuti pakhale kupsinjika maganizo ndipo sikungadzaze. Tiyeni tipumule ndi 1mm, ndipo mupeza gawo lodalirika. Ndiko kulingalira kolondola—zimachitika kalekale chitsulo chisanasungunuke.
Pamapeto pake, kuthamangitsa mtheradi, mwangwiro, mwatsatanetsatane pamalo aliwonse ndi ntchito yachitsiru. Mtengo wopindika umapita molunjika. Luso lenileni ndikuzindikira zinthu zofunika kuziwongolera - malo osindikizira, zolemba zamakalata, malo okwererako - ndikutsanulira njira zanu zonse kuti maderawo akhale angwiro. Zina zonse zitha kuyendetsedwa. Umu ndi momwe mumaperekera gawo lolondola, osati kungojambula bwino. Sikuti ndi nambala chabe patsamba. Ndi za gawo lomwe limagwira ntchito, lokhalitsa, komanso lomveka bwino pazachuma. Ndiwo mzere womaliza.
