Anthu ambiri akamva zitsulo zomwe sizili wamba, amajambula bulaketi yosavuta yomwe ndi yayitali kuposa masiku onse, kapena giya yokhala ndi mano osamvetseka. Ndilo lingaliro lolakwika loyamba. M'malo mwake, ndi dziko lomwe limatanthauzidwa ndi kusakhalapo kwa nambala ya catalog. Sikuti ndi gawo lopindika; ndi za kupanga njira yogwirira ntchito pomwe gawo lopanda alumali limalephera, nthawi zambiri polanga chifukwa cha kutentha, nkhawa, kapena dzimbiri. Vuto lenileni sikungopangitsa kuti izi zitheke, ndikupangitsa kuti zigwire ntchito modalirika ngati palibe chotsatira.
Pakatikati pa Zopanda Mulingo: Ndi Njira, Osati Chogulitsa
Simungathe kulekanitsa magawo awa ndi unyolo wa ndondomeko. Chojambula chimafika pa desiki yanu - nthawi zambiri chojambula choyipa kuchokera kwa mainjiniya - ndipo funso loyamba ndilakuti sitingathe kupanga izi? Ndi cha chiyani icho? Ntchitoyi imalamula chilichonse: zinthu, njira yoponyera, kulolerana kwa makina. Mwachitsanzo, gawo la valavu yotentha kwambiri pafakitale yamankhwala si gawo lachitsulo chosapanga dzimbiri. Zimayamba ngati kuponya ndalama mu aloyi yopangidwa ndi faifi tambala kuti igwire dzimbiri, kenako imapita ku makina olondola a CNC kuti asindikize, ndikutsatiridwa ndi chithandizo chapadera cha kutentha. Gawoli limabadwa kuchokera pamndandanda uwu. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka makumi atatu akuwunjikana luso popanga ndi makina pansi pa denga limodzi, amapeza izi modabwitsa. Mutha kuwona njira yawo patsamba lawo pa https://www.tsingtaocnc.com—samangopereka ntchito; amawonetsa luso lophatikizika. Ndilo fungulo. Kulima sitolo imodzi ndikukankhira kwina kuti mupeze gawo lopanda muyezo ndi njira yolozera zala zinthu zikalakwika.
Kusankha zinthu ndi kumene zisankho zazikulu zoyambirira zimachitika, ndipo pamene zolakwa zimakhala zodula. Makasitomala nthawi ina adalimbikira kuti 316 ikhale yosapanga dzimbiri kuti ikhale ndi malo okhala ndi chlorinated kwambiri, kutchula muyezo wamakampani. Tinakankhira mmbuyo, kunena kuti duplex yosapanga dzimbiri kapena aloyi ya faifi tambala. Anapita ndi 316 kuti apulumutse mtengo. Patatha miyezi isanu ndi umodzi, tinali kukonza makina a aloyi 20. Kodi tikuphunzirapo chiyani? Non-standard nthawi zambiri amatanthauza kuti malo ogwirira ntchito nawonso ndi opanda muyezo. Ma library omwe mumawawona patsamba ngati QSY's, akulemba chilichonse kuyambira chitsulo chonyezimira mpaka ma aloyi opangidwa ndi cobalt, sizinthu zokha; ndi chida chothetsera mavuto osaneneka a chilengedwe.
Gawo la prototyping ndi lankhanza. Ndipamene mapangidwe amalingaliro amakumana ndi zenizeni zenizeni. Mutha kukhala ndi chojambula chokongola cha CAD chanyumba yovuta, yokhala ndi mipanda yopyapyala ku Inconel. Koma kodi njira yopangira chigoba chikhoza kukwaniritsa makulidwe a khoma popanda chilema? Kodi zida za CNC zitha kufikira njira zamkati popanda kupotoza? Takhala ndi mapangidwe omwe amawoneka bwino kwambiri koma amafunikira kuti tipange zosintha zanthawi zonse kuti tigwire chogwirira ntchito panthawi yokonza, ndikuwonjezera 30% kunthawi yanthawi. Uwu ndiye mtengo wobisika wa ntchito yosakhala yanthawi zonse. Si kulephera; ndiye msonkho wa R&D.
Pamene Kuponya ndi Machining Kugundana (Kwenikweni)
Izi ndiye tsatanetsatane wonyezimira kwambiri: kuchokera pamakina kupita kumalo ogulitsira makina. Kwa gawo lokhazikika, muli ndi choyimira. Kwa gawo lopanda muyezo, mumakhazikitsa zomwe zili munkhani yoyamba. Kuponyedwa kwa nkhungu za zipolopolo, zomwe zimadziwika ndi kutha kwake bwino komanso kulondola kwake, zimakhalabe ndi mitundu yosiyanasiyana - mitengo ya shrinkage imasiyana pang'ono ndi batch, makamaka ndi ma aloyi apadera. Katswiri wamakina akuyenera kudziwa komwe datum ili pamakina osaphika. Kodi ndi pamwamba? Bowo loyendetsa ndege? Tinaphunzira izi movutirapo kale popanga makina opangira makina opangira pompa. Chotsatira chake chinali gawo lopangidwa mwaluso lokhala ndi makulidwe a khoma omwe amasiyanasiyana ndi 1.5mm, kupangitsa kuti ikhale yopanda ntchito. Tsopano, ndondomekoyi ikuphatikizapo kuwunika koyambirira kojambula koyamba, kupenta ndi utoto wabuluu ndikulemba zolemba zenizeni za makinawo. Ndizotsika zamakono koma ndizofunikira.
CNC Machining castings sanali muyezo ndi chilombo china. Simukuyamba ndi yunifolomu billet. Mukukankhira pamtundu wovuta, nthawi zambiri wosagwirizana. Kudulira koyamba ndikofunikira - kumakhazikitsa ndege yanu ndipo nthawi zambiri kumawulula subsurface porosity kapena inclusions. Ndikukumbukira giya lalikulu lachitsulo lopanda kanthu pomwe chidacho chinkamveka panjira yoyamba. Tidapeza malo olimba, malo ozizirirapo kuchokera popanga. Njira yonse yamakina idayenera kusinthidwa pa ntchentche, kuchedwetsa chakudya ndi liwiro. Ngati ndinu shopu yopangira makina omwe mumagula zinthu zosaphika kuchokera kwa anthu ena, zomwe zapezekazi zimadzetsa kuyimitsidwa ndikuimbidwa mlandu. Pamene malo opangira makina ndi makina akuphatikizidwa, monga ku QSY, ndemanga zimakhala nthawi yomweyo. The foundry gulu akhoza kusintha kuthira kutentha kapena nkhungu ❖ kuyanika kwa mtanda wotsatira, ndi Machining timu kusintha pulogalamu yawo. Zimasintha vuto kukhala njira yabwinoko.
Ndiye pali geometry yomwe imapatsa olemba mapulogalamu mutu. M'matumba amkati, kudulidwa kwapang'onopang'ono pamasamba opangira ndalama, ma angles odabwitsa. Sikuti ndi luso la 5-axis; ndi za toolpath strategy. Kugwiritsa ntchito chida chotalika kwambiri kungayambitse kupatuka, kuwononga kulolerana. Nthawi zina, mumayenera kupanga ndikupanga chogwiritsira ntchito chosakhazikika kapena bar yotopetsa. Cholinga sikungochotsa zitsulo; ndiko kutero popanda kupangitsa kupsinjika kapena kugwedezeka komwe kungakhudze ntchito yomaliza ya gawolo. Apa ndipamene zaka 30 zakumbuyo QSY imatchula kuti si mzere wamalonda - ndi laibulale ya mayankho am'mbuyomu oti muchotse vuto latsopano, lodabwitsa likafika.
The Alloy Dilemma: Njira Zapadera Zokwera mtengo, Koma Zofunika
Makasitomala amadana ndi mawu a gawo la alloy lopangidwa ndi cobalt. Ndikumvetsetsa. Mtengo wazinthu pa kilogalamu ndi wodabwitsa. Kulungamitsidwa sikuli muzinthu zokha, koma kulephera kumalepheretsa. Tinkapanga chigawo chimodzi cha pulasitiki extrusion die - mbale yovala. Chitsulo chachitsulo chokhazikika chimatha pafupifupi miyezi itatu mumayendedwe otsekemera, otentha polima. Tidazijambula mu aloyi ya cobalt-chromium (mtundu wa Stellite). Makinawa anali owopsa; imagwira ntchito nthawi yomweyo, imafunikira kukhazikika kolimba ndi zida zakuthwa, zapadera za carbide. Koma mbaleyo inatha miyezi yoposa 18. Kusungidwa kwanthawi yocheperako kunachepetsa mtengo wagawolo. Katswiri pano ndi pawiri: kudziwa nthawi yopangira ma alloys apaderawa, komanso kudziwa momwe angagwiritsire ntchito nawo. Si kuthekera komwe mumangogula; mumachimanga kupyolera mu zida zowonongeka ndi matepi osweka.
Kutentha mankhwala a kaloti izi sanali muyezo pambuyo Machining ndi mgodi wina. Kwa zitsulo zambiri zogwira ntchito kwambiri ndi nickel alloys, chithandizo cha kutentha ndi chofunikira kuti tikwaniritse zofunikira zakuthupi - kuuma, mphamvu zolimba, kuthetsa nkhawa. Koma kutentha kutentha kungayambitse kusokoneza. Kutsatira kumafunika kwambiri. Kodi mumagwiritsa ntchito makina ovuta, kutentha, kenako kumaliza makina? Kapena mumamakina mokwanira, kenako kutentha kutentha pang'ono kuti muchepetse kugundana? Palibe yankho labukhu. Zimatengera geometry ya gawolo, machitidwe a aloyi, komanso kulolerana komaliza. Tidayenera kusiya ma batchi chifukwa sitinapezeke molakwika pamagawo atsopano, ngakhale tidagwiritsapo kale aloyi yemweyo. Jiometry iliyonse yatsopano ndi kuyesa kwatsopano.
Kulankhulana: Chida Chovuta Kwambiri Chopanda Chikhalidwe
Zolephera zazikulu sizimayamba chifukwa cholephera luso. Amachokera ku mipata yolumikizana. Injiniya imapanga ntchito. The foundry amaganiza za castability. Wopanga makina amaganizira za kupezeka kwa zida ndi kulolerana. Pamene awa ali magulu osiyana, mumapeza masewera a foni. Chojambulacho chimatanthauziridwa, kenako chimatanthauziridwanso. Cholemba chovuta kwambiri chomaliza chosindikizira (mwachitsanzo, 0.8μm Ra) chikhoza kusokonekera ngati chojambulacho chimangotchula zolemba zonse osati pamatchulidwe ake. Tsopano tikuumirira kuyitanidwa koyambira pantchito iliyonse yovuta, yomwe ndi injiniya wamakasitomala, chitsogozo chathu, ndi makina athu otsogolera onse pamzere. Timadutsa mzere ndi mzere, ndikufunsa chirichonse. Kodi utali wozungulirawu uyenera kukhala wa 3mm, kapena ndikungowoloka? Kodi titha kuwonjezera kachipangizo kakang'ono kofikira pano? Zokambiranazi ndizofunika kwambiri kuposa mapulogalamu aliwonse apamwamba.
Ichi ndichifukwa chake mbiri yamakampani imafunikira. Mukawona ngati kampaniyo Mtengo wa QSY wakhala akusewera ndi kupanga kwazaka zopitilira 30, zikutanthauza kuti mwina adakonza momwe amagwirira ntchito kuti athe kutsogolera zokambirana zamtunduwu. Izo zaphikidwa mu ntchito yawo. Webusaiti yawo, https://www.tsingtaocnc.com, imakonza mautumiki awo mozungulira zopereka zophatikizika - nkhungu ya zipolopolo ndi kuyika ndalama mu makina a CNC. Kapangidwe kameneko sikanangochitika mwangozi; ndi kuyankha ku zofunika zofunika mu zigawo zachitsulo zosakhala zokhazikika dziko: kuphatikiza kopanda msoko kuchokera kuchitsulo chosungunuka kupita ku gawo lomaliza.
Zolemba ndiye mzati womaliza, wosasangalatsa. Kwa gawo lokhazikika, mumatumiza ndi satifiketi yogwirizana. Kwa gawo lopanda muyezo, nthawi zambiri mumafunika dossier yathunthu: ma cert azinthu, ma chart ochizira kutentha, malipoti oyendera nkhani yoyamba ndi data ya CMM, ngakhale zithunzi zamagawo ovuta. Uwu siufulu; ndi traceability. Gawo limenelo likaikidwa m'manda mumsonkhano wa madola mamiliyoni ambiri zaka ziwiri kuchokera pano ndipo funso likubwera, dossier ndiye chitetezo chokha. Kupanga izi mumayendedwe oyenda kuyambira tsiku loyamba ndi chizindikiro chaogulitsa okhwima.
Pamapeto pake, Ndi Za Kuthetsa Vuto Losalembedwa
Ndiye, tikulankhula chiyani kwenikweni ndi zida zachitsulo zomwe sizili zokhazikika? Sitikupanga chinthu chokha. Tikupanga njira yothetsera vuto lomwe silinathetsedwe m'njira yofanana. Mtengo wake suli mu kilogalamu yachitsulo yotumizidwa. Zili m'chidziwitso chophatikizidwa-kumvetsetsa momwe aloyi wopangidwa ndi nickel amayendera mu nkhungu yopangira ndalama, chidziwitso cha malo okwera kuti ateteze kuswana muzitsulo zovuta zoponyera zitsulo, chidziwitso chosankha zokutira koyenera kwa chida cha carbide kugaya cobalt alloy.
Ndi gawo loyendetsedwa ndi zosiyana, osati malamulo. Gawo lirilonse latsopano ndi ntchito yaying'ono, yokhala ndi zoopsa zake komanso njira yophunzirira. Makampani omwe amatha, omwe amamanga mbiri ya zaka za 30 monga QSY, amatero pokonza momwe amachitira zosiyanazi-osati mwa kuzipanga kukhala zokhazikika, koma pokhala ndi ndondomeko yolimba, yolankhulana, ndi yophatikizana yomwe ingathe kuyamwa kusinthasintha ndikuperekabe gawo lomwe limagwira ntchito. Nthawi ina mukadzawona RFQ yosagwirizana, yang'anani modutsa zojambulazo. Onani ngati wogulitsa akufunsa za ntchitoyo, chilengedwe, kulephera kwa gawo lapitalo. Ndicho chizindikiro kuti ali mu bizinesi yothetsa mavuto, osati kungodula zitsulo.
