Anthu ambiri akamva 'zigawo zapadera za alloy,' amaganiza za pepala lodziwika bwino: Inconel 718, Hastelloy X, CoCrMo, ndi manambala awo ochititsa chidwi amphamvu komanso kukana dzimbiri. Ndiwo mayendedwe amalonda. Chowonadi chomwe chili pansi pa sitolo, makamaka pakupanga ndalama zovuta komanso kukonza makina, ndi chilombo chosiyana. Kusiyana pakati pa chiphaso changwiro cha zinthu ndi gawo logwira ntchito, lodalirika ndi pamene ntchito yeniyeni imachitika. Sikuti kukhala ndi aloyi; ndikumvetsetsa zomwe zimachitika kwa icho kuchokera ku chitsulo chosungunuka kupita ku gawo lomaliza.
Zapadera mu Aloyi Zapadera Si Kemistry Yokha
Tengani pempho wamba: gawo la aloyi lochokera ku faifi wotentha kwambiri kuti mugwiritse ntchito turbine. Wothandizira amapereka AMS spec. Ndiwo mzere woyambira, osati mapeto. Chikhalidwe 'chapadera' chimayamba ndikufufuza. Sikuti ma alloys onse apamwamba kapena zosungunula zakuthupi zimakhala zofanana. Tsatanetsatane wa zinthu, kusungunuka kwenikweni ndi kuyengedwa kwa mpheroyo—izi zimakhudza mochenjera kutha kwa mpheroyo, ndipo pambuyo pake, kuchita bwino. Taphunzira kuyenerera magwero athu osati ndi zolemba zokha, komanso ndi mayeso ang'onoang'ono. Inconel 625 ya ogulitsa ikhoza kutsanulira mosiyana pang'ono ndi wina, zomwe zimakhudza kudzaza kwa nkhungu ndi kukhulupirika komaliza m'magawo oonda.
Apa ndipamene ntchito ya nthawi yayitali ikufunika. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka makumi atatu pakupanga ndi kupanga makina, mwachiwonekere awona kusintha kosiyanasiyana kwa zaka zambiri. Chikumbukiro cha bungwe ndichofunika kwambiri. Mumamanga laibulale yamalingaliro: Gwero la A's 316L ndilabwino kwa mavavu akulu, koma popanga nkhungu movutikira, mawonekedwe ang'onoang'ono, ovuta, Kutentha kwa Source B kumakhala ndi madzi abwinoko. Izi sizili pamasamba aliwonse.
Kapangidwe kake kokha—kaya kamene kamakhala kachikopa kake kapadera kapena kachulukidwe ka ndalama—kumafuna 'kusintha aloyi' yakeyake. The matenthedwe mphamvu pa solidification kupanga microstructure. Kuthamanga kwambiri, ndipo mumayika chiopsezo cha micro-porosity; pang'onopang'ono, ndipo kukula kwa tirigu kungafooketse gawolo. Kwa ma alloys apadera, zenera la magawo oyenera nthawi zambiri limakhala locheperako. Chithandizo cha kutentha pambuyo poponyedwa chimakhala chosakambitsirana, osati chosankha, kuti muchepetse kupsinjika ndikukwaniritsa gawo lomwe lakonzedwa. Kuchita molakwika izi kungapangitse gawo lamphamvu kwambiri la alloy kukhala brittle.
Machining: Kumene Zongopeka Zimagwirizana Zowona
Uyu ndiye wodzichepetsa kwambiri. Muli ndi gawo lopangidwa bwino la cobalt-chromium alloy. Chemistry ndi yangwiro, X-ray ndi yoyera. Tsopano muyenera kuyiyika pa makina a CNC kuti mukwaniritse zobowoleza zolimba komanso kumaliza. Apa ndi pamene mapulojekiti ambiri amakumana ndi ndalama zosayembekezereka komanso kuchedwa.
Special alloys ntchito-olimba. Chida chodulira chomwe chimazengereza, ngakhale kwa kamphindi, chikhoza kupanga pamwamba kwambiri kuposa chida chokha. Tawononga zoyika zodula mumphindi pophunzira izi. Kuziziritsa sikungokhudza kuziziritsa; ndi za kupewa izi-umitsa ntchito ndi kuonetsetsa chip kusamutsidwa. Kuthamanga kozizira kolakwika kapena mtundu kungayambitse kuwotcherera kwa chip. Njira zopangira zida izi ndizodzitchinjiriza: kudulidwa kosasinthasintha, mwaukali kuti mulowe pansi pa gawo lolimba la ntchito kuchokera pakupita koyambirira, m'malo mopepuka, skimming mosamala.
Kukonzekera kwa Toolpath kumayenera kuwerengera kupsinjika kotsalira kwa gawolo. Nthawi zina, mukamangirira ndi makina mbali imodzi, gawolo limayenda pang'ono ngati kupsinjika kwamkati kumakhazikika. Ndizokhumudwitsa. Mutha kupirira pa opareshoni yoyamba, koma mutha kupeza kupotoza mutatha kumasula. Izi nthawi zambiri zimabweretsa kutsatana kwa makina ovuta, kuzungulira kwapang'onopang'ono, kenako kumaliza kukonza. Si njira yachangu, koma ndi yodalirika. Kuphatikizika kwawo CNC makina Kuthekera ndikofunikira pano - kukhala ndi makina opangira pansi padenga limodzi kumalola kuti pakhale njira yobwerezabwereza, yoyendetsedwa ndi mayankho popanda mlandu pakati pa ogulitsa osiyana.
Mfundo Zolephera ndi Zosokoneza Zobisika
Sikuti nkhani iliyonse imakhala yopambana. Kumayambiriro, tinali ndi pulojekiti ya gawo la nickel alloy losachita dzimbiri lamakampani opanga mankhwala. Idapambana mayeso onse wamba. Koma muutumiki wakumunda, zinalephereka chifukwa cha corrosion corrosion cracking mu mng'alu wa geometry womwe sitinauone kuti ndi wofunika kwambiri. Kodi tikuphunzirapo chiyani? Chilengedwe ndi chilichonse. 'Special alloy' ndi yapadera pazochitika zenizeni. Tsopano timakhala nthawi yochuluka tikukambirana za malo ogwirira ntchito - kuchuluka kwa mankhwala, kutentha, kulongedza kwa cyclic - monga momwe timasindikizira.
Kugwirizana kwina kofala kuli pakati pa malingaliro abwino ndi kupanga. Wojambula angatchule makoma owonda kwambiri ndi makona amkati mkati mwazitsulo zosapanga dzimbiri kuti achepetse kulemera. Koma kodi chitsulo chosungunukacho chingadzaze gawolo popanda kuzizira msanga? Kodi chida chingafikire mbali yamkati imeneyo kuti ipange makina kapena kuyang'ana? Nthawi zina, chothandizira chofunikira kwambiri ndikuwonetsa kusinthika pang'ono-kuwonjezeka kwa radius 0.5mm, kusintha kwa ngodya yojambula-komwe kumapangitsa gawolo kukhala lopangidwa bwino popanda kusokoneza ntchito. Uwu ndiye mgwirizano wothandiza womwe umatanthawuza kupambana.
Kutsimikizira kwabwino kumakhalanso kovutirapo. Kuyesa kolowera kwa utoto ndikokhazikika, koma pazigawo zofunika kwambiri zodalirika, nthawi zambiri timakankhira zochulukirapo. Mwachitsanzo, ma radiography kuti muwone ngati mkati mwake muli porosity m'magawo ofunikira akuponya. Zimawonjezera mtengo ndi nthawi, koma kulumpha ndikutchova njuga. Chigamulocho chimadalira ntchito ya gawolo. Kodi ndi nyumba yonyamula katundu kapena nyumba yosafunikira? Mawu akuti 'zigawo zapadera za aloyi' zikutanthawuza ntchito yoposa wamba, kotero ndondomeko zathu zoyendera nthawi zambiri zimafunika kuti zigwirizane ndi zomwezo.
Ubwino Wophatikizidwa: Kuchokera ku Melt kupita ku Machine
Ichi ndichifukwa chake chitsanzo cha maziko okhala ndi makina amkati, monga momwe tafotokozera https://www.tsingtaocnc.com, ndizomveka pazinthu izi. Njira yophunzirira ndiyolimba. Gulu lopanga makina limatha kuuza gulu loponya, Gulu ili la magawo linali ndi mawanga olimba apa, zomwe zimapangitsa kuti chida chivale kwambiri. Gulu loponya likhoza kufufuza: kodi kunali kusintha pang'ono kwa kutentha kwa kuthirira? Kusintha kwa gating system? Ndemanga iyi ndi golide.
Komanso amalola ophatikizana ndondomeko kukhathamiritsa. Mwachitsanzo, kusankha kuchuluka kwa masheya kuti musiye makina. Mochulukira, ndipo mukuwononga nthawi ya aloyi ndi makina okwera mtengo. Pang'ono kwambiri, ndikusintha pang'ono kapena kusakwanira pamwamba kumatanthauza kuti gawolo silingayeretsedwe mpaka kukula kwake. Kukhala ndi magulu onse awiri pansi pa denga limodzi kumakupatsani mwayi wodziwa bwino gawo la geometry ndi alloy.
Kuphatikiza apo, kuwongolera kumakhala kovutirapo. Zigawo zapadera za alloy, post-casting and between Machining ops, nthawi zambiri zimakhala zamtengo wapatali komanso zomvera. Kuwasunga pamalo olamuliridwa, kuwatsata mosamalitsa, ndikuchepetsa mayendedwe amachepetsa chiopsezo cha kusakanikirana, kuwonongeka, kapena kuipitsidwa. Malo ophatikizika amathandizira unyolo wazinthu izi kwambiri.
Kuyang'ana M'tsogolo: Ndilo Luso
Ngakhale kupita patsogolo kwa mapulogalamu oyerekeza opangira (monga MAGMA) ndi mapulogalamu a CNC, kupanga zida zapamwamba zapamwamba zimakhalabe luso lodziwika bwino. Pulogalamuyi imakupatsirani poyambira, koma mmisiri - injiniya woyambira, katswiri wamakina - amapanga zosintha zomaliza potengera kuwona, kumveka, komanso kumva. Momwe chitsulo chimathirira, mtundu wa chip panthawi yokonza, phokoso la kudula.
Tsogolo, ndikuganiza, lagona pakutenga zambiri zachidziwitso chachinsinsi ichi. Koma pakadali pano, imakhala mwa anthu komanso machitidwe amakampani omwe adadutsapo, monga momwe ntchito yazaka 30 ikadakhalira. Ayenda pakusowa kwazinthu, kutengera magiredi atsopano a alloy, ndikuyika ndalama muukadaulo wolondola wa CNC kuti adule.
Chifukwa chake, pakuwunika gwero la zigawo zapadera za aloyi, yang'anani kupyola mndandanda wazinthu ndi malo osungira makina. Yang'anani umboni wa malingaliro ophatikizika awa, othetsa mavuto. Funsani za ntchito yovuta yomwe amaliza. Yankho lake lidzakuuzani zambiri kuposa kabuku konyezimira. Chogulitsa chenicheni si gawo la aloyi chabe; ndi chidziwitso chogwiritsidwa ntchito chomwe chimatsimikizira kuti gawolo limagwira ntchito monga momwe likufunira, modalirika, pomwe likufunika.
