Urumva Stellite yajugunywe cyane mumahugurwa ninama zamasoko, akenshi nkugufata-kubintu byose bigoye cyangwa bishingiye kuri cobalt. Ngiyo imyumvire ya mbere itari yo gukuraho. Ntabwo ari ikintu kimwe ahubwo ni umuryango, cyane cyane amavuta ya cobalt-chromium, kandi delta ikora hagati yamanota nka Stellite 6, 12, cyangwa 21 ni nini. Nabonye imishinga inanirwa kuko umuntu yerekanye gusa icyogajuru ku gishushanyo, ukeka ko byose ari super-material. Ntabwo aribyo. Guhitamo hagati ya karubone nyinshi yo gukuramo cyane na karubone yo hasi kugirango irwanye ingaruka nziza ntabwo ari amasomo - ni itandukaniro riri hagati yintebe ya valve imara amezi atandatu cyangwa imyaka itatu.
Casting Conundrum na Shell Mold Ukuri
Gukorana naya mavuta ntabwo ari nko gutunganya ibyuma byoroheje. Ibirimo byinshi bya cobalt na chromium bituma bakora akazi katoroshye niba utitonze. Kera kare, twagerageje guca Stellite 6 hamwe na karbide isanzwe. Igisubizo? Ubuso bwometseho, kwambara ibikoresho byihuse, nibice bisa neza. Umurongo wo kwiga wari muremure. Ukeneye gushiraho gukomeye, geometrike nziza ya rake, kandi rimwe na rimwe, ugomba kwemera ko gusya ari intambwe yanyuma yo kwihanganira bikomeye.
Aha niho inzira yo hejuru ifite akamaro kanini. Ibikoresho bitagabanijwe neza ntibishoboka gukiza mubukungu binyuze mumashini. Twagize ibitekerezo byiza hamwe Igikonoshwa kubice bigoye. Ihagarikwa ryimiterere hamwe nubuso burangirira kumurongo mwiza woguha amahirwe yo kurwana mugice cya CNC. Igabanya ingano yibyo bikoresho bigoye ukeneye kuvanaho, bikabika neza igihe nigiciro cyibikoresho.
Ndibuka umushinga wihariye kubakiriya ba peteroli bakenera kwambara. Porotipire yambere, yakozwe binyuze muburyo bworoshye bwumucanga, yari ifite uturere twinshi tudahuye hamwe no kugabanuka kwihishe. Gukora imashini byari intambara. Twahinduye uburyo bwuzuye bwibishishwa kugirango umusaruro ukorwe, dufatanya n’uruganda ruzi gukemura ibibazo biranga amavuta - nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Imyaka mirongo itatu yibanda kuri casting no gutunganya bivuze ko babona imbaraga zikenewe. Ntushobora kujugunya gusa kandi wizere ko irindi duka ryerekana imashini. Kugira munsi yinzu, cyangwa hamwe nabafatanyabikorwa bahujwe, ni urufunguzo. Ibicuruzwa byasohotse byasohotse hamwe na microstructure imwe, kandi ishami ryacu rya CNC ryashoboraga kwihanganira kwihanganira bore nta guhindura ibikoresho bitagira iherezo.
Imashini ya CNC: Imbyino Nziza hamwe no Gukomera
Gukora icyogajuru ni isomo ryo kugaba ibitero. Ntushobora gutinyuka gukata kwawe, cyangwa uzakora gusa-gukomera hejuru muburyo butagaragara. Ariko nanone ntushobora kubyikuramo gusa. Ahantu heza ni ibiryo bihoraho, biringaniye hamwe nigikoresho gityaye. Twishingikirije cyane kuri ceramic cyangwa CBN yinjiza kugirango turangize passes kumanota akomeye. Coolant ntishobora kuganirwaho, kandi ntabwo ari ugukonja gusa - ifasha mukwimura chip. Imipira miremire, ifatanye izengurutse igikoresho? Nuburyo bwihuse bwo kwangiza igice nabafite ibikoresho.
Ikintu kimwe gikunze kwirengagizwa ni uguhuza. Kuberako usunika igikoresho kandi ibikoresho birakomeye, igice kigomba gufungwa rwose. Ikiganiro icyo ari cyo cyose cyangwa kunyeganyega bisobanurwa mu buryo butaziguye na micro-frake hejuru yubuso, bigahinduka ingingo yo gutangiriraho ibice muri serivisi. Twimukiye muri hydraulic fixture kubintu bikomeye bya Satelite. Nibiciro byiyongereye, ariko bihendutse kuruta gukuraho $ 5,000 $ kubera kubutaka butarangiye neza kuva fixture flex.
Nyuma yo gutunganyirizwa kenshi guhishura ukuri kwa casting. Twigeze gutunganya icyiciro cya Stellite 21 igitambaro cya turbine. Kuri benshi, inzira yinzira yari yoroshye. Kuri bibiri, twabonye rimwe na rimwe, gukata kugabanuka ahantu runaka. Yerekanaga itandukaniro ryaho mubukomere, birashoboka gutandukanya karbide kuva kuri stade. Tugomba gukurura ibyo byombi kugirango twongere ubushyuhe kugirango duhuze imiterere - gutinda ntawashakaga. Irashimangira ko niyo hamwe nubushakashatsi bwiza, ukeneye ubugenzuzi bukomeye bwinjira, rimwe na rimwe birenze igenzura ryoroshye rya chimie kugirango ushiremo ibizamini bya ultrasonic cyangwa eddy bigezweho.
Guhitamo Amavuta: Ntabwo bigeze gusa
Icyiciro kidasanzwe cya alloys niho ubwubatsi nyabwo bubera. Icyogajuru cyicaye hamwe na nikel ishingiye kuri alloy nka Inconel, ariko ibyifuzo byabo biratandukanye. Icyogajuru cyo kwambara no kurwanira ubushyuhe buringaniye kugeza hejuru; nikel-ibinure byinshi kubwubushyuhe bwo hejuru bwo hejuru no kwangirika. Nabonye ibishushanyo aho Inconel 625 yabanje gusobanurwa kubushyuhe bwo hejuru bwa valve, ariko uburyo nyabwo bwo kunanirwa kwari ugushushanya insinga biturutse kumuvuduko mwinshi. Guhindukira kuri karubone nyinshi Icyogajuru amanota nka Stellite 3 yakemuye ikibazo ku giciro gito.
Iki cyemezo matrix kirakomeye. Ugomba kubaza: Ese umwanzi wibanze gukuramo, isuri, kwangirika, cyangwa guhuriza hamwe? Ubushyuhe bwo gukora ni ubuhe? Hoba hari ingaruka? Ibikoresho nka QSY'portfolio, ikubiyemo imiryango ya cobalt na nikel, ni ingirakamaro kuko batabogamye kubisubizo bimwe. Barashobora, cyangwa bagomba gushobora, gutanga inama bashingiye kubisabwa. Kurugero, kububiko bwa pompe mubidukikije byumunyu uhura nibishobora kwangirika ndetse no gutitira ibintu, barashobora gutanga igitekerezo cya Stellite 6 hejuru yicyuma kitagira umwanda aho kuba nikel ikomeye, ihenze cyane.
Kunanirwa kw'ibiringiti. Umukiriya yigeze gutsimbarara kuri Stellite 1 kubintu byose kuko yari ifite urutonde rukomeye. Babikoresheje ibice biterwa nubushyuhe bwumuriro ningaruka zumucyo. Ibice byacitse. Icyogajuru 1 kiravunitse. Twagombaga kubanyuza mumpapuro zamakuru kugirango twerekane ko Stellite 6, hamwe nubwiza bwayo bwiza kandi irwanya-kwambara neza, byari amahitamo meza kuri uwo mutwaro ufite imbaraga. Imibare yamakuru ntabwo ivuga inkuru yose; uburambe bwo murwego.
Kwishyira hamwe kuva gushonga kugeza kumashini
Isomo rikomeye ryize ni uguhuza gukina no gutunganya. Iyo ifashwe nka silos zitandukanye, imishinga ya satelite yamennye amafaranga nigihe. Uruganda rukeneye kumva icyo umukanishi ahura nacyo. Ibintu byoroshye nko kongeramo ibintu bihoraho, bitanga inguni zingirakamaro, kwemeza irembo hamwe n’ahantu hashobora kuba hashobora kuba ahantu hatari hake, kandi ukirinda ibice bito cyane bikonje cyane bishobora gukora cyangwa kumena imashini.
Ibigo byakoreye mumyanya yombi imyaka myinshi, nkuko byavuzwe Qingdao Qiangsenyuan Technology Co., Ltd. (urashobora kubona uburyo bwabo kuri https://www.tsingtaocnc.com), kugira ubwo bumenyi bwashinze imizi. Amateka yabo yimyaka 30 mugukina no gutunganya CNC ntabwo ari umurongo wo kwamamaza gusa; byerekana ko binjije izi ngingo zububabare. Bashobora kuba batekereza kubijyanye no gutunganya ibibanza mugihe bashushanya ibishushanyo, nuburyo bigomba kumera. Kubakoresha-nyuma, uku kwishyira hamwe kugabanya ingaruka. Ntabwo ugura casting gusa; urimo kugura ibintu byakozwe.
Urugero rufatika: Twari dukeneye urutonde rwimpeta zoroshye kandi zometseho kashe muri Stellite 12. Ikibazo cyari ukurinda kugoreka mugihe cyo gutunganya nyuma yo guterwa. Inzira isanzwe yaterera, kugabanya imihangayiko, imashini, n'ibyiringiro. Utanga ibicuruzwa byahujwe yatanze igitekerezo cyahinduwe: guta, gukora imashini itoroshye kugeza kuri net-net, hanyuma uburyo bwa kabiri butunganya ubushyuhe, hanyuma hakurikiraho gutunganywa neza. Iyi ntambwe yinyongera, yavutse kuburambe hamwe nimyitwarire yibikoresho mumurongo wose, yatanze ibice, bihamye. Nuburyo bwimikorere nuance itandukanya ibice umucuruzi hamwe nigisubizo cyumufatanyabikorwa.
Kureba Hejuru y'Izina
Hanyuma, birakwiye ko tumenya ko Stellite ari izina ryamateka ya Deloro Stellite (ubu ni igice cya Kennametal). Hariho ibingana na cobalt-chromium ivanze nabandi bakora. Mu masoko, cyane cyane kubintu bititaye ku biciro ariko bifite amajwi menshi, kuzuza ibikoresho bisa birashobora gutsinda cyane. Urufunguzo ni ukwemeza imikorere, ntabwo ari chimie gusa. Twakoresheje ibizamini byo kwambara kumurongo kuri Stellite 6 hamwe na CoCr-A rusange ivanze na pompe ya pompe. Imikorere yari imwe mu mibare, iganisha ku kuzigama gukomeye.
Ariko, ibi ntabwo ari ibyifuzo. Kubintu bikomeye, byizewe cyane mubikorwa byindege cyangwa kirimbuzi, gukurikiranwa hamwe no kwemeza urusyo rukomeye hamwe nibikoresho byanditseho akenshi bifite agaciro. Nubundi guhamagarwa. Ingingo ni ukumenya ko ufite amahitamo no gushingira umwanzuro kubyo usaba hamwe nibisobanuro byerekana ingaruka, ntabwo ari ingeso.
Noneho, mugihe ukorana na Stellite, tekereza kuri gahunda. Ntabwo ari umukungugu wubumaji utonyanga kukibazo. Nibikoresho bisaba agaciro kayo kugerwaho gusa binyuze muburyo bwo gutoranya amanota, kugenzura no guhuza ibikorwa kuva mububiko kugeza igice cyarangiye, no gusobanukirwa neza nibyo bizahura na serivisi. Fata ubwo burenganzira, kandi buraramba bidasanzwe. Wibeshye, kandi ni isomo rihenze.
