Xa abantu abaninzi besiva 'ukulungiswa kwesinyithi', baba nomfanekiso weleyile okanye iziko lomlilo. Leyo yimbono yokuqala ephosakeleyo. Akukhona nje ngokususa izinto okanye ukugalela isinyithi esityhidiweyo. Luluhlu olupheleleyo lwezigqibo, ukusuka ekukhethweni kwealloyi ukuya ekugqibeleni komphezulu, apho ubugcisa bokwenyani-kunye nemigibe eqhelekileyo-ilele khona. Abaninzi bacinga ukuba ukunyamezelana okungqongqo kuhlala kungcono, okanye ukuba nawuphi na umatshini we-CNC unokusingatha i-Inconel. Oko kucinga kukhokelela kwiindawo ezilahliweyo kunye nohlahlo lwabiwo-mali oluvuthuzayo. Emva kokuchitha iminyaka kule ntsimi, ndiwubonile umsantsa phakathi kwethiyori yencwadi yesikhokelo kunye nenyani yomgangatho wevenkile. Kuloo msantsa apho ufunda khona.
Isiseko: Iqala ngokuCasa
Awukwazi ukuthetha nge serious processing metal ngaphandle kokuqalisa ekuqaleni: ukubunjwa. Apha kulapho i-DNA yenxalenye iseti. Isiphene apha sisenokungabonakali de kube yinkqubo yokugqibela, xa sele uchithe iiyure zomsebenzi kuyo. Oku sikufunde kabuhlungu kwangethuba ngeqela lezindlu zempompo. Ukubunjwa kweqokobhe kujongeka kugqibelele, kodwa ngexesha lokudinwa, sabetha umngxuma ongaphantsi komhlaba. Ilahleko iyonke. Kulapho uqaphela ukuba ulawulo lomgangatho ayilokuhlola nje okokugqibela; ilawula iqondo lobushushu lokungunda, izinga lokugalela, uyilo lokungena. Iinkampani ezifumana oku ngokufanelekileyo, njenge Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), yakha loo minyaka engama-30 yamava kwinkqubo yabo. Abathengisi nje iicastings; bathengisa ukuqiniseka ukuba ingqibelelo yezinto eziphathekayo ikhona ngaphambi kokuba kwenziwe nayiphi na i-chip.
Ukugaywa kotyalo-mali lelinye irhamncwa. Kwizinto ezintsonkothileyo, ezinodonga olucekethekileyo kwi-stainless okanye ezo zinto zikhethekileyo, isoloko ikuphela kwendlela. Kodwa indibano 'yomthi wewax' kunye nokwakhiwa kweqokobhe leceramic bubugcisa obuninzi kunenzululwazi. Ukwahluka okuncinci kwi-viscosity ye-slurry okanye ixesha lokumisa kunokukhokelela ekuqhekekeni kwegobolondo ngexesha le-dewaxing. Ndikhumbula iprojekthi yecandelo le turbine apho satshintshela kwi-cobalt-based alloy. Iresiphi eqhelekileyo yeqokobhe ayikwazanga ukumelana nobushushu obuphezulu bokugalela kunye nomothuko we-thermal. Siye sagqiba ukusebenzisana ne-Foundry-elungileyo, khumbula-ukuphuhlisa idyasi yobuso be-zirconia. Isebenzile, kodwa yongeza iiveki ezintathu kwixesha lokukhokela. Lurhwebo olo.
Yiyo loo nto ukukhetha iqabane kubalulekile. Ivenkile ebonelela ngokubumba iqokobhe kunye nokufakwa kotyalo-mali, njengemiboniso yepotfoliyo ye-QSY, iyaluqonda urhwebo. Banokukucebisa ukuba isibiyeli esilula sigqithise kakhulu kwi-investment casting, okanye ukuba umzimba wevalvu onamajelo angaphakathi unokuwufuna. Olo lwazi luhlanganisiweyo luthintela ii-RFQ ezininzi ezingalunganga.
Umdaniso we-CNC: Apho ukuchaneka kuhlangana neMathiriyeli
Kulapho i-abstract iba yinto ebonakalayo. Umatshini we-CNC emva kokuphosa ayingomsebenzi wokucoca nje. Yingxoxo kunye nemathiriyeli. Oomatshini bentsimbi yokuphosa kakuhle; kukuxolela. Kodwa thatha iqhekeza lesisombululo esiphathwe nge-17-4 PH engenasici, okanye ngakumbi, i-alloy esekelwe kwi-nickel njenge-Inconel 718, kwaye yonke into iyatshintsha. Ijiyometri yesixhobo sakho, ukutya kwakho kunye nezantya, uxinzelelo lwakho lokupholisa kunye nohlobo-zonke ziyahlaziywa.
Eyona mpazamo inkulu ndiyibonayo ngabaprogram baphatha zonke iintsimbi ngokufanayo. Baza kusebenzisa indlela yesixhobo eyenzelwe intsimbi ethambileyo kwisiqwenga seMonel, kwaye emva koko bazibuze ukuba kutheni bevutha ngokufaka rhoqo ngemizuzu emihlanu kwaye baqinise umphezulu kwindawo engenakulinganiswa. Kwii-superalloys, udinga ukuseta okuqinileyo, ii-engile zehariki ezilungileyo, kwaye ngamanye amaxesha ude ulibale ukupholisa kwamanzi ngokuthanda umoya woxinzelelo oluphezulu okanye i-MQL (ubungakanani obuncinci bokuthambisa) ukunqanda ukuqhekeka kwe-thermal. Yinto ephikisayo.
Sasinomsebenzi wokwenza iflenji enkulu ukusuka kwisanti yentsimbi ephindwe kabini. Isixhobo sasinzima, kwaye utyando lokuqala yayiyi-face mill ukuseka i-datum. Sasebenzisa i-carbide esemgangathweni yokufaka. Intshukumo embi. Incoko yayisoyikeka, yaye umphezulu wawungathi yibhodi yokuhlambela. Siyeke, sitshintshele kwi-wiper insert kunye ne-wiper cut edge ebukhali kwaye sinciphise ubunzulu be-radial cut, ukwandisa ukutya kancinci. Umahluko wawubusuku nemini. Ngalo mzuzu, uhlengahlengiso kwi-fly-fly, ezalwe ngokubona iitshiphusi (umbala wazo kunye nokumila kwazo zikuxelela yonke into), ezahlula umvelisi wamacandelo kwinyani. processing metal ingcali.
UMtyholi kwiiNkcukacha: Ubushushu, Uxinzelelo, kunye noGqiba
Umatshini wenza uxinzelelo. Ixesha. Ukuba wenza ibholithi elula, mhlawumbi ayinamsebenzi. Kodwa ngokuchaneka okuphindaphindiweyo okanye isibiyeli se-aerospace esithwele umthwalo, uxinzelelo olushiyekileyo luya kuyijija inxalenye ngokuhamba kwexesha okanye kwimisebenzi elandelayo. Ndihlala ndikhuthaza ukuthomalalisa uxinezeleko phakathi kokuphumelela kunye nokugqiba izinto ezibalulekileyo. Ewe, yongeza inyathelo, kodwa ikusindisa kwintliziyo ebuhlungu yenxalenye yokunyamezelana kwi-CMM ngoLwesihlanu kwaye uphume ezintlanu ngoMvulo.
Emva koko kukho unyango lobushushu oluchazwe ngumxhasi. Kuya kufuneka uyazi ukuba loo nto iyitshintsha njani into. Inxalenye isenokuza kuwe iqholiweyo, uyirhabaxa, emva koko iphume iye kucinywa nokushushumbisa, ize ibuyele kuwe ukuze uyigqibezele. Loo ndawo iphathwa bubushushu iyaqina, idla ngokurhawuzelela. Izixhobo zakho zokugqiba kufuneka ziphendule kweso sikhumba. Sake sagqiba igiya phambi kokuba lukhuni, ukuya kwiprofayile egqibeleleyo. Emva kokuqina kwetyala, bekufuneka sicoceke. Kodwa ukugqwethwa kwakungalingani, kwaye siphulukene nokuchaneka kweprofayili. Isifundo: Ngamanye amaxesha kufuneka ushiye isitokhwe ukuze ugaye okokugqibela okanye ujike nzima emva kokuphathwa kobushushu, nokuba umzobo awuwubizi ngokucacileyo. Kufuneka ucinge amanyathelo amaninzi ngaphambili.
Iimfuno zokugqiba umphezulu yenye indawo eqhelekileyo yokubhideka. I-callout ye-32 Ra ayithethi nje malunga nokuqhuba ukutya okucokisekileyo. Imalunga neradiyasi yempumlo yesixhobo, ukungcangcazela kokudambisa, kwaye ngamanye amaxesha nokuzinza kwesantya sokusonta. Ukugqiba isibuko kwisitulo sevalvu yentsimbi, sinokusebenzisa isixhobo sedayimane esinenqaku elinye kwileyile echanekileyo, kodwa kuphela emva kokuqinisekisa ukuba indawo leyo ayinaso nasiphi na isikali esirhabaxa ekugalweni okanye kunyango lobushushu. I-speck enye ye-alumina efakwe kumphezulu inokuyonakalisa yonke i-pass.
IiNuances zeMathiriyeli: Ayiyiyo yonke iNsimbi eyiNtsimbi
Le yinduli endiya kufela kuyo. Igama eliqhelekileyo lentsimbi alinamsebenzi kwi processing metal. Ngaba sithetha nge-1018 ephantsi-carbon? 4140 chromoly? 316L ayinabala? Okanye amabakala emvula-enza lukhuni njenge-15-5 PH? Ngamnye unobuntu bakhe. 304 ibala, umzekelo, unomkhwa ombi wokusebenza nzima. Ufuna izixhobo ezibukhali kunye nokuzibandakanya okungaguqukiyo; ukusiyeka isixhobo sisigwebo sokufa.
Kwaye emva koko uhamba kwiindawo ezingaqhelekanga-i-cobalt kunye ne-nickel-based alloys. Ezi zihlala zisetyenziselwa iindawo eziphakamileyo: ukushisa okuphezulu, ukubola okuphezulu. Ukuzicutha kuncinci malunga nokusika kwaye ngaphezulu malunga nokucheba okulawulwayo. Izinto eziphathekayo azivelisi lula; iyazilwela. Ukulindela ubomi besixhobo kufuneka kuphoswe ngefestile. Uyilo lwenkqubo yakho yonke, ukusuka kulungiso ukuya kwisicwangciso sendlela yesixhobo, imalunga nokulawula lo mlo. Amava enkampani ayabonakala apha. Xa umthengisi ofana ne-QSY edwelisa ezi ngxubevange njengezinto ezikhethekileyo, ithi ngokungagungqiyo batyale imali kwisixhobo esifanelekileyo, oomatshini abafanelekileyo abanetorque ephezulu kunye nobungqongqo, kwaye okona kubaluleke kakhulu, umonde kunye nokukwazi ukubaqhuba ngenzuzo ngaphandle kokusika iikona.
Ndikhumbula ndikhangela icandelo leHastelloy C-276 kumxhasi wekhemikhali. Iivenkile ezininzi ezicatshulwe ngokusekelwe kumthamo woshicilelo. Inye kuphela ebuzwayo malunga nesicelo, ukuxhathisa okufunekayo kwimithombo yeendaba ethile, kwaye yacebisa inkqubo eyahlukileyo kancinane yasemva komatshini wokuphucula umaleko wechromium oxide. Loo venkile yawufumana umsebenzi. Lulwazi oluthe ngqo olongeza ixabiso ngaphaya kwesicatshulwa esisisiseko somatshini.
Udibaniso: Ukusuka kwiShicilelo ukuya kwiNxalenye, ngokungenamthungo
Amanqaku okugqibela onobuchule processing metal utyando alwenzi nje inyathelo elinye kakuhle. Iququzelela lonke uhambo ukusuka kwimathiriyeli ekrwada ukuya kwindawo ethunyelwe ngenqanawa. Yilapho imodeli yeenkonzo ezidibeneyo-i-casting, machining, unyango lokushisa, ukugqiba-ubonisa ukubaluleka kwayo. Xa iziko elinye lilawula ukuhamba, uxanduva lokuphendula lucacile. Akukho kwalatha ngomnwe phakathi kwe-Foundry kunye nevenkile yomatshini ukuba i-dimension ivaliwe.
Kwindibano enzima esasisebenza kuyo, isiseko sasiyi-nodular iron casting, indlu yayiyi-investment-cast 316L, kwaye i-shaft yangaphakathi yenziwe ngomatshini ukusuka kwi-Inconel 625 bar stock. Ukulungelelaniswa kwabathengisi abathathu abahlukeneyo ngamaxesha okukhokelela kwizinto eziphathekayo, iinkqubo, kunye nemigangatho yomgangatho yayiliphupha elibi. Thelekisa oko ngokunikezela yonke ipakethe kumboneleli womthombo omnye. Unxibelelwano luqina ngakumbi. Banokucwangcisa ukuphosa ukuba bafike kanye njengoko amandla e-CNC evuleka. Bayaqonda ukuba i-engile yokuphosa idrafti inokuchaphazela njani ukulungiswa komatshini. Olo mbono lubanzi luphelisa umngcipheko omkhulu kunye nokulibaziseka.
Olu lutshintsho olufihlakeleyo kushishino. Iyasuka ekubeni yivenkile yemisebenzi eyenza imisebenzi ecacileyo iye ekubeni liqabane lemveliso elingumnini wenkqubo. Xa ujonge ukunikezelwa kwenkampani-njengokubona ukubunjwa kweqokobhe, ukuphosa utyalo-mali, kunye ne-CNC yokwenza konke phantsi kophahla olunye kwindawo efana ne-QSY-awuboni nje uluhlu lwenkonzo. Ubona isakhono sokulawula izinto ezintsonkothileyo zendalo processing metal ukusuka ekuqaleni ukuya ekupheleni. Yiloo nto ehambisa ukuthembeka, kungekhona nje iinxalenye. Kwaye ekugqibeleni, yiloo nto yonke injineli kunye nomthengi ayifunayo ngokwenene: kungekhona nje iprosesa, kodwa iqabane elifumana izandla zabo ezingcolileyo ngendlela efanayo, obona iitshiphusi kwaye uva ubushushu, kwaye ngubani owenza iminxeba yomgwebo engekho kumzobo.
