Xa usiva u-'Co 21', ukuba ingqondo yakho itsibela kwifomula enye, echazwe ngokungqongqo, sowungekho endleleni. Kwimingxunya yotyalo-mali kunye nobuchwephesha be-CNC, olo bizo luhlala luvusa ingxoxo ngakumbi kunokucaca. Ayifani nokubiza i304 engenastainless; sisishunqulelo, isiqalo sencoko ebandakanya ubushushu, izinto zomkhondo, kwaye ekugqibeleni, ukusebenza phantsi kwetotshi okanye isixhobo. Ndibone ii-RFQ ezininzi apho umntu abethe nje 'i-Co 21' kumzobo kwaye alindele umlingo, elibala ukuba umlingo-okanye intloko ebuhlungu-ikwiinkcukacha ezithile kunye nokukwazi kwe-Foundry ukuzitolika.
I-Spec lilayini yokuQalisa, hayi uMgqa wokuGqiba
Masifumane ikhonkrithi. Kumsebenzi wethu kwi Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), isicelo sokuba a Co 21 icandelo lidla ngokuhlala ngokubhekisele kwinto efana ne-Haynes 21 okanye ialloy ye-nickel ye-cobalt-chromium-molybdenum-tungsten efanayo. Into yokuqala esiyenzayo asikokucaphula; kukucazulula. Ithini indawo yokusebenza? Ingaba yeyokutywina kwe turbine yegesi, idolo elifakelweyo, okanye icandelo levalvu enxibe kakhulu ekusetyenzweni kweekhemikhali? I-chemistry yesiseko inokuba yi-ballpark, kodwa umtyholi-umahluko phakathi kwenxalenye ehlala kwiinyanga ezintandathu kunye neyodwa ehlala iminyaka emithandathu-kwinkqubo yesibini kunye nesicwangciso somatshini.
Ndikhumbula iprojekthi kwiminyaka embalwa edlulileyo yomthengi we-aerospace ye-MRO. Babefuna indawo yestator vane shroud, ecacisa Co 21 ngokulinganayo. Sifumene ingxubevange ye-cobalt ekwazi ukumelana nobushushu ifanele inkcazo ebanzi. Ukubunjwa kweqokobhe lokungunda kuhambe kakuhle, ukuchaneka komda kwakuseqongeni. Kodwa i-post-casting, ngexesha lonyango lokufudumala kwesisombululo, sibetha i-snag. Umjikelo wokunceda uxinzelelo esiwusebenzisileyo, ngokusekwe kwiprothokholi esemgangathweni yeealloyi ezifanayo, awuzange ufezekise ukuhanjiswa kwe-carbide ngokufanelekileyo kwiimeko zabo zokudinwa komjikelo ophezulu. Inxalenye yadlula i-QA, kodwa ekuvavanyeni kwabo ibhentshi, ubomi bokukhathala bube malunga ne-15% ngaphantsi kwenjongo yabo. Ngaba yayikukusilela? Akunjalo. Yayisisifundo. Izinto eziphathekayo zazibuchwephesha Co 21, kodwa isicelo sasifuna a Co 21 kunye nembali yobushushu obuthile. Siye saphinda saqhuba ibhetshi ngotshintsho olulungisiweyo, olude lozinziso, kwaye yabetha uphawu. I-spec sheet ayizange itshintshe; inkqubo yethu yenza.
Apha kulapho amava evenkile abala khona. Nabani na unokuthenga iingots zealloy. Ayinguye wonke umntu oneminyaka engama-30-odd yokwenza ipateni, ubunjineli bokubumba, kunye nonyango lobushushu lwasemva kokuphoswa ukuba isiseko esifana ne-QSY siqokelele. Ufunda ukuba ngezi superalloys, iiparamitha zoomatshini onokuthi uzisebenzise kwintsimbi ziya kutshisa nje izinto ezifakwayo kwaye zisebenze-nzima umphezulu ukuze ulibale. Udinga isantya esisezantsi sokusika, amazinga aphezulu okutya, ukuseta okuqinileyo, kunye nesipholisi esimalunga nolawulo oluchanekileyo lobushushu kunokuthambisa nje izikhukhula. Ngumdaniso owahlukileyo ngokupheleleyo.
Ukufunyanwa kwezinto eziphathekayo kunye neTrap elinganayo
Enye intloko esebenzayo yinto ekrwada ngokwayo. Ethetha Co 21 ayikuqinisekisi ukuba ufumana imathiriyeli kwilitye elinye lokusila, ngolawulo olufanayo lokungcola, njengenxalenye ye-OEM. Sisebenza ngee-alloys ezikhethekileyo ezibandakanya ezo zisekwe kwi-cobalt, kwaye sakhe ubudlelwane kunye nezingqusho esizithembileyo. Kodwa ngamanye amaxesha uhlahlo lwabiwo-mali lomthengi lubaqhubela ekubeni bafune imathiriyeli elinganayo kwezinye iindawo. Le yindawo enkulu yomngcipheko.
Sinemeko kunye nomenzi wempompo. Basithumelele eyabo imithombo Co 21 isitokhwe sebha yeCNC machining yeepleyiti zokunxiba zenkonzo eqatha. Iicerts zazikhangeleka zilungile ephepheni. Kodwa ngexesha lomatshini, abaqhubi bethu baqaphela ukuba iichips zaziziphatha ngendlela eyahlukileyo-zinentambo eninzi, zincinci kunokuba bekulindelwe. Ukunxitywa kwesixhobo nako kwakungaqhelekanga. Siye sathula saqhuba eyethu ispectrometry. Ichromium kunye nemolybdenum zaziphakathi koluhlu, kodwa umkhondo wesilicon kunye nemanganese bezicimile. Yayingeyiyo ingxubevange embi, kodwa yayingelulo olwantlukwano luchanekileyo uyilo lwabo lwempompo luqinisekisiweyo. Ukuyisebenzisa kwakunokukhokelela kwintlungu engalindelekanga okanye ukubola ebaleni. Siye sayihlaba umkhosi, saxoxa ngotshintshiselwano lwentsebenzo, kwaye bakhetha ukuba sinikezele ngezinto ezikwijelo lethu eliqhelekileyo. Ixabisa ngaphezulu ngaphambili kodwa igcine ukusilela okunokwenzeka kwibala.
Kungenxa yoko le nto kwiwebhusayithi yethu, tsngtaocnc.com, sigxininisa ukudibanisa ukuphosa kunye nomatshini. Xa silawula inkqubo ukusuka kwintsimbi etyhidiweyo ukuya kwindawo egqityiweyo yomatshini, siphelisa ukuguquguquka okukhulu. I Co 21 (okanye nayiphi na i-alloy) iyancibilika, iphoswe, iphathwe ngobushushu, kwaye iqhutywe phantsi kophahla olulodwa, kunye nentambo enye eqhubekayo yokulawula inkqubo kunye noxanduva. Idatha evela kwisithando somlilo sazisa ishedyuli yonyango lobushushu, nto leyo echaza isicwangciso somatshini. Awunakuyifumana loo nto kwivenkile yomsebenzi ukuba oomatshini abathengiweyo bengenanto.
CNC Machining: Apho ithiyori idibana Toolpath
Ukucoca ezi alloys kulapho irabha idibana nendlela. Asiyonto yabatyhafileyo. Awunakuvele uphose isingqusho esisemgangathweni kuyo. Sithetha malunga nezixhobo eziqinileyo ze-carbide, iijometri ezithile zobushushu obuphezulu, kwaye ngamanye amaxesha nokuba yi-CBN (i-cubic boron nitride) yokugqiba. Ukuseta ukuqina kubaluleke kakhulu; nayiphi na incoko iya konakalisa imfezeko yomphezulu ebaluleke kakhulu kuxhathiso lokudinwa.
Inkcukacha ehlala ingahoywa yimeko yemathiriyeli phambi kokuba ibethe kumatshini we-CNC. Kuba Co 21 ukuphoswa, ngaba bakwimeko efana ne-cast, isisombululo bayanyangwa, okanye baluphele ngokupheleleyo? Ubulukhuni kunye ne-ductility iyahluka kakhulu. Sakhe sayenza ibhetshi ye-as-cast Co 21 izindlu. Ijometri yayintsonkothile, ineendonga ezibhityileyo. Kwimeko ye-as-cast, impahla yayinoxinzelelo oluthile olushiyekileyo kwaye yayithambile. I-Machining yahamba kakuhle, kodwa emva kokuba senze i-post-machining efunekayo yokuqina kweminyaka, amanye amacandelo amancinci abonisa ukugqwetheka okuncinci-amawaka ambalwa e-intshi, kodwa ngokwaneleyo ukuba abe ngaphandle kokunyamezela indawo yokukhwelana. Safunda. Ngoku, kumacandelo anomlinganiselo obalulekileyo, sihlala sisenza umsebenzi orhabaxa womatshini kwindawo ethambileyo, emva koko sisebenzise unyango lokugqibela lobushushu, silandelwe kukugqiba ukukhanya ukuya kuthi ga kwijiyometri. Yongeza inyathelo, kodwa iqinisekisa umphumo.
Iqhinga elipholileyo sesinye isihloko esipheleleyo. Ngala ma-alloys, ukuveliswa kobushushu kwinqanaba lokusika kunamandla. Kufuneka uyilawule, kodwa kwakhona ucinge ngekhemistri. Ezinye iialloyi ze-cobalt ezisebenza kakhulu zinokuziva zinovakalelo kwisalfa ethile okanye izongezo zeklorini kwizinto ezipholileyo, ezinokuthi ziphembelele ukuqhekeka koxinzelelo lwe-corrosion kamva. Sisebenzisa i-pH engathathi hlangothi, i-semi-synthetic coolants kwaye sizigcine ngononophelo. Yinkcukacha encinci kwiskimu esikhulu, kodwa kweli shishini, iinkcukacha ezincinci ziyiskimu esikhulu.
I-Advanteji yokuDityaniswa: Ukusuka kwi-Shell Mold ukuya kwiCandelo eligqityiweyo
Oku kundibuyisela kumbindi wendlela yokusebenza edityanisiweyo ngokuthe nkqo njengeQSY iphatha imathiriyeli efana Co 21. Inkqubo yokuphosa iqokobhe lokungunda esiyisebenzisayo ilungile ekufezekiseni okuntsonkothileyo, kufutshane ne-net-shape geometries ezi nxalenye zexabiso eliphezulu zihlala zifuna. Xa usenza i-injini ye-injini entsonkothileyo okanye iprototype yokufakelwa kwezonyango Co 21, ufuna isitokhwe somatshini esincinci esilandelayo-mhlawumbi nje i-0.5mm ngobuso. Oku konga kwixesha elikhohlakeleyo lomatshini kunye nenkcitho yezinto ezibizayo.
Kodwa ukudibanisa kungaphezulu nje kwamanyathelo okugcina. Imalunga nokuhamba kolwazi. Iqela labasunguli liyazi ukuba Co 21 ukuphosa ubuninzi bodonga oluthile kuya kuba nesakhiwo esithile senkozo. Banxibelelana oko kwiqela lenkqubo ye-CNC, abanokuthi emva koko bacwangcise iindlela zabo zesixhobo kunye nokubambelela ukuze basebenze neso sakhiwo, hayi ngokuchasene naso. Iqela lonyango lobushushu lifumana idatha kumacala omabini ukuze kulungiswe imijikelo. Yimpendulo yempendulo oyifumanayo kuphela kumashumi eminyaka phantsi kophahla olunye, usebenza kuyo yonke into ukusuka kwintsimbi ekhandiweyo ukuya kwi-alloys esekwe kwi-nickel kwaye, kunjalo, usapho lwe-cobalt.
Ndibone iiprojekthi zisilela kumakhonkco obonelelo adityanisiweyo. Inkampani enye yenza ukuphosa, enye iphatha ubushushu, eyesithathu isenza oomatshini. Ulwazi luyalahleka. Ingcibi yoomatshini iba lukhuni, igugile Co 21 inxalenye leyo iphupha elibi ukusika kwaye akazi ukuba kutheni kunzima kangaka. Bagxeka umbandela. Mhlawumbi isicoci sobushushu sigugile kwiqondo lobushushu elingafanelekanga kwisixhobo esicetyiweyo somatshini. Xa zonke zidityanisiwe, ezi ngxaki ziyilwa ngaphambi kokuba kugalelwe umngundo wokuqala.
Ngaphaya kolu bizo: Umbono wePragmatic
Ke, yintoni i-takeaway Co 21? Yiphathe njengodidi olusebenzayo, hayi imveliso. Ixabiso layo liqondwa kungekhona xa uyi-odola, kodwa xa uchaza ukuba iya kwenziwa njani, iphathwe, kwaye igqitywe. Impumelelo yenxalenye ixhomekeke ekuphatheni ukutyunjwa kwe-alloy njengomgca wokuvula kwingxoxo enzulu yobugcisa malunga nokusebenza, okusingqongileyo, kunye nokwenziwa.
Kwiinjineli kunye nabathengi, ingcebiso yam kukujonga ngaphaya komgca wezinto ezibonakalayo kumzobo. Thetha nomthengisi wakho kwinkqubo. Buza: Athini amava akho ngonyango lobushushu lwasemva kwesi sicelo? Uhlangabezana njani noxinzelelo loxinzelelo ngaphambi komatshini? Ithini iparamitha yakho esemgangathweni emiselwe le meko? Iimpendulo ziya kukuxelela ngaphezulu kakhulu kunesatifikethi sokusila esinako.
Ekugqibeleni, Co 21 sisixhobo. Yeyona nto inamandla yokunxiba, ubushushu, kunye nokumelana nomhlwa. Kodwa njengaso nasiphi na isixhobo esichanekileyo, ukusebenza kwayo kuxhomekeke ngokupheleleyo kwizakhono zezandla, kunye nobunzulu bokuqonda, ukukhokela ukusetyenziswa kwayo ukusuka kwizinto eziluhlaza ukuya kwinxalenye egqityiweyo. Leyo yi-alloy yokwenyani-umdibaniso wekhemistri echaziweyo kunye noqokelelweyo, ubugcisa obusebenzayo.
