Xa usiva 'i-tilt gravity die casting', umfanekiso wokuqala odla ngokuvela yile nkqubo igudileyo, izenzekelayo egalela isinyithi esingenasiphako. Enyanisweni, ingaphezulu elawulwayo, ingcebiso ngabom. Ingcinga engundoqo ilula: endaweni yokulahla isinyithi esinyibilikisiweyo ngokuthe ngqo ezantsi, uthambekisa ukungunda ukuze isinyithi siyigcwalise ngokucothayo, sinciphisa isiphithiphithi. Kodwa kulapho ithiyori idibana khona nomgangatho wevenkile-ukufumana isantya sokuthambeka kunye ne-engile elungile kwindawo entsonkothileyo, ngakumbi ngealloys ezinobuqili, kulapho amashumi eminyaka othuli olusisiseko lugcina khona.
IiMechanics ze-Tilt kunye nesizathu sokuba ingeyiyo nje iGimmick
Masiqhawule 'i-tilt'. Akukho malunga nomatshini onqabileyo, nangona ezo zikhoyo. Kumalunga nokulawula intsimbi yangaphambili. Kwi-gravity yesiqhelo yokugalela, ufumana umphumo we-waterfall. Kwinto efana nendlu yevalve yentsimbi ecekeceke-ebiyelweyo, yiresiphi yokufakwa kweoksidi kunye nokubaleka kwenkungu. Inkqubo ye-tilt ivumela ukuba isinyithi sikhwele udonga lomqolo. Cinga ngokugalela ibhiya ngokucothayo ngokuchasene nokuyigalela phakathi. Eyangaphambili ikunika intloko engcono, le yokugqibela ibe yingxaki. Ngokwamagama esinyithi, 'intloko' ebhetele ithetha ukubanjiswa kwerhasi okumbalwa kunye nokwakheka okuziinkozo okungaguquguqukiyo.
Ndikhumbula umsebenzi esawenza kwiminyaka edlulileyo kwi-impeller yepompo kwi-duplex stainless. Umxhasi wayenemiba nge-shrinkage porosity kwi-hub ephakathi usebenzisa iindlela zendabuko. Saxoxisana ngendlela ethambekileyo. Intandabuzo yokuqala yayimalunga nexesha lomjikelo - licotha ngokungathandabuzekiyo ekugaleleni. Kodwa intlawulo yayikwizinga elincitshisiweyo lenkunkuma. Ngokuthamba, sakhokelela kwiziko lobushushu lokusa ngokuqikelelwa ngakumbi, nto leyo eyenza ukubeka ukubanda kunye nokunyuka kuphantse kube ngumsebenzi wenzululwazi kunomdlalo wokuqikelela. Isivuno siphuculwe malunga ne-15%, nto leyo yeendleko zemathiriyeli, yathethelela ukugalelwa okucothayo.
Apho kukhanya ngenene kukwezo ngxubevange ezikhethekileyo i-QSY ihlala iphatha, njenge-nickel-based based. Ezi zi-viscous, ziqina ngokukhawuleza, kwaye zibiza. Awunakho ukufikelela kwisiphithiphithi esikhokelela ekufakweni onokufumana kuphela ngexesha lomatshini. Ukuthambeka kuba yimfuneko, hayi ukhetho. Sisisombululo esisebenzayo sokulawula ukugcwalisa ngendlela ethi ukugalela ngokuthe ngqo kuhlala kungahambelani neejometri ezintsonkothileyo.
Imiba yeMathiriyeli: Ayiko-Tilt-Fits-All
Oku kujongwa okuqhelekileyo. Iiparamitha ezithambekileyo zentsimbi engwevu lihlabathi ngaphandle kwezo zealloyi esekwe kwicobalt. Ngentsimbi etyhidiweyo, ujongana nokuguquguquka okuhle kodwa utyekelo lokwakheka kwenkunkuma ukuba ukugalelwa kunobundlobongela kakhulu. Isantya esiphakathi sokuthambeka siyasebenza. Kodwa tshintshela kwi-high-nickel alloy, kwaye umdlalo uyatshintsha. Intsimbi 'imfutshane', ayihambi ngokukhawuleza. Udinga i-engile ethe kratya yokuqala yokuthambeka ukuze wenze intsimbi ihambe, emva koko icothise kakhulu, igqibezela elilawulwayo ukondla amacandelo aqina ekugqibeleni.
Sifunde oku ngendlela enzima kwiprojekthi yokuqala yesibiyeli esikwaziyo ukumelana nobushushu. Ukusebenzisa inkqubo ye-iron-optimized tilt kwi-nickel-chromium alloy kubangele ukuvalwa okubandayo ekupheleni komngxuma. Intsimbi yayihlinza phambi kokuba umngxuma ugcwale. Ulungiso lwalungekokukhawulezisa ukuthambeka nje; yayimalunga nokufudumeza ukufa kwangaphambili ngokwahlukileyo kwaye uqalise ukuthambeka ngakumbi ukuze ufumane umphambili obalekayo, emva koko uyicothise ezantsi. Ngulo mdaniso phakathi kweqondo lobushushu, isantya sokuthambeka, kunye ne-engile oyifumanayo ekujikeni amaxesha ambalwa.
Apha kulapho amava ezinto ze-Foundry, njengeminyaka engama-30-odd iQSY ikhankanya, iba yinto ephathekayo. Ayikokuba nezixhobo nje kuphela; imalunga nokuba nenkqubo yenkumbulo yento esebenza nge-Inconel 718 xa ithelekiswa ne-304 engenasici. Inkqubo yokuthambeka ikhulisa ukubaluleka kwezi zinto zifihlakeleyo. Indlela yokwenza igeneric iya kukunika igeneric, ehlala inesiphene, iziphumo.
Uyilo lwezixhobo kunye noDie: Iqhawe elingadungwanga
Uyilo lokufa lokuphosa ukuthambeka lwahluke kakhulu. Isango lokungena kunye nenkqubo yembaleki ilula ngandlel' ithile kuba awuxhomekekanga kwinkqubo entsonkothileyo yokulawula ukuhamba-i-tilt iyakwenza oko. Kodwa kufuneka ucinge ngokwendlela yentsimbi njengoko i-die ijikeleza. I-isite kufuneka ibekwe ukuze ibe yeyona ndawo isezantsi ekuqaleni kwethambeka, kwaye umoya kufuneka usebenze kuso sonke isindululo esijikelezayo, hayi nje ukuzaliswa okumileyo.
Ndikhe ndayibona ifa apho iminyango ibekwe ngokugqibeleleyo ukugalelwa ngokuthe nkqo kodwa yaba yimigibe engenamsebenzi yomoya xa ithe yathambeka ngama-45 degrees. Uphela uneepokotho zerhasi kwezona ndawo zingathandekiyo. Isisombululo sikholisa ukubandakanya ngaphezulu, imingxuma emincinci ecaleni komgca wokwahlula kwaye ngamanye amaxesha neendawo zokuvula zeceramic zexeshana kwiindawo eziphakamileyo kwindawo yokuqala yokufa. Yinto emdaka, esebenzayo yokusombulula iingxaki.
Ubomi bokufa ngomnye unobangela. Ukucotha, ukudibana rhoqo kwentsimbi eshushu ekhwela udonga lokufa kunokukhokelela kwiipateni ezahlukeneyo zokudinwa kwe-thermal xa kuthelekiswa nomothuko wokugalela ngokupheleleyo. Sihlala sibona ukulunga ngakumbi, ukujonga ubushushu kwiindawo zokuzalisa kwangoko ngokuhamba kwexesha. Kuthetha ukuba ishedyuli yakho yogcino lokufa kufuneka iphendule koku. Asiyonkqubo yokubeka-kwaye-uyilibale; ifuna ingqwalasela ethe kratya kwimeko yesixhobo somjikelo ukuya kumjikelo.
Ukudityaniswa neeNkqubo zeSekondari: Ikhonkco loMatshini
Le yintlawulo ebalulekileyo. Owenziwe kakuhle i-tilt gravity die casting ayisiyomveliso yokugqibela; yi-preform ekufutshane ne-net-shape ye-CNC machining. Ukungaguquguquki okuzisayo liphupha likamachini. Xa isandi sangaphakathi kunye nokungabikho kokufakwa kanzima kuqikelelwa, unokutyhala i-CNC feeds kunye nesantya esinzima. Awunaxhala malunga nokubetha ipokotho yesanti okanye iqoqo leeoxides eziya kuqhekeza i-200 yeedola zokuphela.
Kwiziko eliphatha zombini ukuphosa kunye nomatshini ngaphakathi endlwini, njengoseto oludityanisiweyo olucetyiswe ziinkonzo ze-QSY, le synergy inkulu. Iqela lokuphosa liyazi kakuhle into efunwa ngoomatshini ngokwemigangatho yedatha, isibonelelo esincinci sesitokhwe, kunye nokufana. Xa ulawula ukuzaliswa ngokuthambeka, ufumana ukuncipha okuqikelelweyo ngakumbi, okuthetha ukuba ungabeka indawo kwindawo yokufa ukuze unciphise ukugqwetheka komatshini okulandelayo. Ijika imisebenzi emibini eyahlukeneyo ibe yinkqubo enye eqhubekayo.
Uvavanyo lwangempela kumatshini wokulinganisa wokulungelelanisa (CMM). Amalungu aphuma kwisiphithiphithi sokugalela ahlala ebonisa ukuguquguquka kobukhulu obungahambelaniyo ngokucocekileyo nokufa - luxinzelelo olungacwangciswanga oluvela kupholiso olungalinganiyo. Amalungu e-Tilt-cast, kumava am, abonisa iipateni. Ukuba kukho ukutenxa, kuyaphinda-phinda kwaye kulandelelwe umva kwi-deflection okanye iprofayile yobushushu, into onokuthi uyilungise ngokwenene.
Unyino kunye neeNgxaki zokwenyani zeHlabathi
Asiyombumbulu yomlingo. Owona mda mkhulu yinxalenye yejometri. Imingxuma enzulu, imxinwa? Kunzima. Isinyithi sinokulahlekelwa bubushushu obuninzi ngaphambi kokuba sifike ezantsi. Ngamanye amaxesha kufuneka udibanise i-tilt kunye ne-counter-gravity encinci yokuncedisa okanye usebenzise ukongezwa kokufa okutshisayo. Yongeza ubunzima. Kwizinto ezilula kakhulu, ezixananazileyo, iindleko kunye nexesha lenkqubo yokuthambeka zisenokungathetheleleki. Indawo eswiti yindawo entsonkothileyo ephakathi apho imfezeko ibalulekile.
Ixesha lomjikelo, njengoko kukhankanyiwe, lide. Isigaba sokugalela siyacotha, kwaye ngamanye amaxesha ukufa kufuneka kubanjwe kwii-engile ezithile ngexesha lokuqiniswa ukunceda ukondla, okubopha umatshini. Kwizinto eziphezulu, eziphantsi kwexabiso eliphantsi, le nto i-deal-breaker. Le nkqubo yeyemithamo ephantsi, amacandelo anexabiso eliphezulu. Cinga ngofakelo lwe-aerospace, imibutho yeevalvu ezikhethekileyo, amacandelo eemoto asebenza kakhulu - iindawo apho kugxininiso lwemathiriyeli ye-QSY ilungelelaniswa.
Ekugqibeleni, kukho into yomntu. Yinkqubo entsonkothileyo ngakumbi ukuseta nokubeka iliso. Umsebenzisi kufuneka aqonde oko akubonayo ekugcwaliseni kwaye axhotyiswe ukwenza uhlengahlengiso oluncinci. I-automation encinci kunerobhothi egalelwe kwifa elimileyo. Urhweba ngobuchule obuthile bolawulo kunye nomgangatho. Kwimarike yanamhlanje, kwinxalenye echanekileyo, lurhwebo ngakumbi nangakumbi iinjineli ezizimisele ukwenza. Injongo ayikokudlala nje; yinto ethembekileyo, icandelo elinobuchule elingasileli ebaleni. Kwaye rhoqo, oko kuqala ngokulula, ukuthambeka ngononophelo.
