Uma uzwa 'izingxenye zomshini we-ductile iron', into yokuqala evelayo cishe yileyo ncazelo ejwayelekile: amandla amahle, i-ductility ethile, ukumelana nokugqokwa okuhloniphekile, ukonga imali. Kodwa leyo yinkulumo yencwajana. Lapho iba ngokoqobo, nalapho amaphrojekthi amaningi akhubeka, kusekuhunyushweni kusuka kulelo phepha ledatha kuya engxenyeni yangempela esesitezi sesitolo, ngaphansi komthwalo. Igebe phakathi kwezakhiwo zempahla ezikahle kanye neqiniso lesakhi sabalingiswa, esakhiwe ngomshini, nesihlanganisiwe yilapho kwenzeka khona umsebenzi wangempela. Ngibone amadizayini amaningi kakhulu aphatha i-ductile iron njengento elula yokufaka esikhundleni sensimbi noma i-iron empunga, kuphela ukuhlangana nezinkinga ngengxoxo yomshini, ukugxila kwengcindezi okungalindelekile ezigabeni ezincane, noma ukusebenza okungahambisani nenqwaba. Akuyona impahla; iwumsebenzi ozwela inqubo.
Isisekelo Sokusakaza: Konke Kuqala Esikhunjeni
Awukwazi ukukhuluma ngokwethembeka izingxenye zemishini ye-ductile iron ngaphandle kokungena ohlelweni lokulingisa kuqala. Izakhiwo zemishini zibhakwa khona lapho. Isakhiwo se-spheroidal graphite - lawo maqhuqhuva asinika i-ductility - sintekenteke ngesikhathi sokuqina. Izinga lokupholisa, umkhuba wokujova, ngisho nezinga lokushisa lensimbi lapho lishaya isikhunta, zonke zidlala indima enkulu. Ingxenye enehabhu eliwugqinsi nezipikha ezincane ingaba nama-microstructures ahlukene kakhulu (ngakho-ke, izakhiwo) kulezo zigaba ezahlukene. Ngikhumbula igiya elingenalutho esake salithola; ibukeke iphelele, iphumelele ukuhlolwa kobukhulu obuyisisekelo, kodwa yehluleka ngendlela emangalisayo ekuhloleni ukukhathala. Umlandu? I-shrinkage porosity ifihlwe kuwebhu, umphumela oqondile wesistimu yokugenca engaklanyelwe kahle engazange yondle ingxenye ewugqinsi ngendlela efanele. Lo mdwebo ubufuna iBanga 65-45-12, kodwa esakuthola kuleyo ndawo ebucayi kwakubuthakathaka, kufiphele.
Kulapho-ke kubalulekile khona ukuqeqeshelwa umsebenzi. Isitolo esikuqonda kahle lokhu, njenge-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), neminyaka engamashumi amathathu kugobolondo nokufaka utshalomali, sinenkumbulo yemisipha yalokhu. Abagcini nje ngokuthela insimbi; baphethe isayensi yokuqinisa. Ngoba izingxenye ze-iron ductile ezibona imithwalo eguquguqukayo - cabanga ngemizimba yama-valve e-hydraulic, ama-compressor crankshafts, noma izingxenye zokulengisa ezisindayo - lesi sisekelo asinakuxoxisana. Ukufakwa kwe-slag encane noma ukujova okungalungile kungase kube indawo yokuqala yokuqhekeka komugqa.
Ukukhetha phakathi kokubunjwa kwegobolondo nokusakazwa kwe-investimenti ye-ductile iron kuvame ukwehlela ekubeni yinkimbinkimbi nezidingo zokuqeda phezulu. Ezingxenyeni ezinamavesi angaphakathi noma ama-cores ayinkimbinkimbi, ukubunjwa kwegobolondo kunikeza ibhalansi enhle. Kodwa uma udinga umumo oseduze nenethi onemininingwane ehlukile yendawo kanye nokusalungiswa okuncane, ikakhulukazi ezintweni ezincane, eziyinkimbinkimbi, ukunemba kokusakazwa kwe-investimenti kungasindisa imali eningi ekwenzeni imishini elandelayo. Ukuhlaziywa kwezindleko nezinzuzo eziqala esigabeni sokuklama, hhayi ukucabanga ngemuva.
Imishini: Lapho Ithiyori Ihlangana Nebhithi Yethuluzi
Lesi yisigaba lapho okucatshangwayo kuhlolwa khona. Imishini yensimbi ene-ductile ihlukile kunensimbi. I-abrasive, ngenxa ye-graphite, futhi ingaba gummy. Yenza isivinini sakho, okuphakelayo, noma ijiyomethri yamathuluzi ibe yiphutha, futhi uzoshisa kokufakwayo noma uthole indawo eqinile, emagebhugebhu ezoguga ngokushesha. Ngifunde lokhu kabuhlungu kusenesikhathi, ngizama ukusebenzisa indlu yephampu yensimbi enezingqimba ezilungiselelwe insimbi ye-carbon. Amathuluzi ahlala uhhafu ubude, futhi ukuqedwa kwangaphandle kwakubi, okuholela ezinkingeni zokuvuza kwezimpawu ekuhlanganisweni.
Ama-graphite flakes ensimbi empunga asebenza njengama-chip breaker, okwenza kube lula ukuwenza ngomshini. I-ductile iron's nodular graphite ayikwenzi lokho. Udinga amathuluzi abukhali, ane-positive-rake, ngokuvamile anezingubo ezikhethekile ezifana ne-AlTiN, futhi kufanele uqaphele ukushisa. Vumela ingxenye ishise kakhulu, futhi ungakwazi ngempela ukushintsha i-microstructure phezulu, udale ungqimba oluqinile, olushwabene okuyiphupho elibi lokucubungula noma ukusebenza okwengeziwe. Ukupholisa okufanelekile akukona nje ukuphila kwamathuluzi; imayelana nokugcina izakhiwo ezibonakalayo ozikhokhele ekulingiseni.
Yingakho ukusebenzisana nomphakeli ophethe kokubili ukusakaza kanye CNC imishini endlini, njenge-QSY, ingahlela izinto. Baqonda ukuziphatha kwezinto ezibonakalayo kusukela ekuncibilikeni kuya engxenyeni eqediwe. Bayazi ukuthi ukucindezelwa okusalayo okuvela ekubunjweni kungathinta kanjani ukugoqa nokusika, futhi bangalungisa isu labo lomshini ngokufanele. Iqeda ukukhombana ngomunwe phakathi kwe-Foundry kanye nesitolo somshini lapho ukubekezelelana kuphuthelwe. Iluphu yempendulo iqinile.
Umbuzo we-Alloy: Akuyona yonke i-Ductile Iron Elinganayo
I-ASTM A yibanga elivamile, kodwa lokho nje kuyisiqalo. Ezingxenyeni ezisendaweni ebolayo noma emazingeni okushisa aphakeme, ungena ku-ayina eyingxube ye-ductile - i-silicon-molybdenum (SiMo) yokumelana nokushisa, noma amamaki ane-nickel alloyed ukugqwala nokuguga. Sibe nephrojekthi yengxenye yesithando somlilo eyayidinga ukusebenza okuqhubekayo ku-800°C. I-iron ejwayelekile ye-ductile ngabe i-graphitized futhi yehlulekile. Sahamba ne-high-silicon ductile iron, eyakha ungqimba oluzinzile lwe-silicon oxide, kodwa yenze lokho okubalulekile kwaba inselele nakakhulu emshinini. Bekuwukuhwebelana, kodwa okulungile kwesicelo.
Ngezinye izikhathi, ukukhetha akuyona ngisho nensimbi ye-ductile. Ngokuguga okudlulele noma umthelela, ungase ubheke i-ADI (Austempered Ductile Iron), ethola ukwelashwa okushisayo ukuze uthole amandla amangalisayo nokuqina. Noma, ezingxenyeni zokucubungula amakhemikhali ezibola kakhulu, i-high-nickel austenitic ductile iron (Ni-Resist) ingaba impendulo. Iphuzu liwukuthi, ukucacisa i-ductile iron akucacile kakhulu. Udinga ukuchaza indawo yesevisi - ingcindezi, izinga lokushisa, imidiya, ukulayisha ngomjikelezo - ukukhetha ibanga elilungile. Umhlinzeki onolwazi ngama-alloys akhethekile, njengoba kukhonjisiwe kuphothifoliyo ye-QSY ene-cobalt ne-nickel-based alloys, usevele ecabanga ngaleli zinga; bathola ukuthi ukukhethwa kwezinto ezibonakalayo kuqhutshwa isicelo.
I-nuance eyodwa evame ukunganakwa umehluko phakathi kwezakhiwo ze-matrix ze-ferritic ne-pearlitic kumamaki ajwayelekile. I-matrix ye-ferritic (insimbi eningi, i-pearlite encane) inikeza i-ductility engcono kanye nokumelana nomthelela kodwa amandla aphansi nobulukhuni. I-matrix ye-pearlitic inamandla futhi ilukhuni, ingcono ukugqokwa, kodwa i-ductile encane. Ungathonya lokhu ngokwelashwa kokushisa kwangemuva kokusakazwa. Ngelinye iphini lokujika, kodwa kufanele wazi ukuthi udinga ukulijika.
Izingibe Zomhlaba Wangempela kanye Nokuzwakala Kwekhwalithi
Ngale kwemibiko yelebhu, kukhona uhlangothi oluthintayo, olucishe lubonakale ekwahluleleni izingxenye zemishini ye-ductile iron. Umsindo owenziwe ingxenye enhle uma ushaywe kancane uwumsindo oshubile, oqinile, hhayi i-ping ebukhali. Ingaphezulu le-blast shot-clean cleaned inokwakheka okufanayo, okumpunga kwe-matte, ngaphandle kwesihlabathi esishile noma ukuvala okubandayo okusobala. Ngesikhathi somshini, ama-chips kufanele aphume amancane, ama-C aphukile, hhayi ama-tangles anezintambo noma uthuli olude. Lawa amasheke e-QC angakahleleki owakhayo ngokuhamba kwesikhathi.
Ugibe olukhulu ukuziba imisebenzi yesibili. Ithi une-ductile iron manifold edinga ukucwecwa noma ukupendwa. Uma ukulingisa kungahlanzwanga kahle - ukudutshulwa kuqhume, bese kuhlanzwa ngamakhemikhali ukuze kukhishwe noma yisiphi isihlabathi esisele noma isikali - ukunamathela kuzohluleka. Ukunamathela kuyinkinga enkulu. Sake saba nenqwaba yezingxenye ezaba namabhamuza lapho kuhlolwa isifutho sikasawoti. Imbangela yayiyizinsalela ze-silicate ezincane ezivela esihlabathini esibunjwayo okungekho noyedwa owacabanga ukuyihlola ngemva kokuqhuma.
Enye inkinga evamile ukuzinza kwe-dimensional, noma ukuntuleka kwakho, ngemva komshini onzima. Uma ukusakaza kungakaqedwa ngokufanelekile ingcindezi (imvamisa umjikelezo wokukhipha isisu), kunganyakaza ngokumangazayo ngemva kokusikeka kokuqala okusindayo, kulahle lonke uhlelo lwakho olucophelelayo lwe-CNC. Kuyisinyathelo esengeza izindleko nesikhathi, kodwa ukweqa kuwukugembula. Umphakeli onokwethenjelwa uzoba nephrothokholi evamile yalokhu esekelwe engxenyeni yejometri nokuqina kodonga.
Ukuhlanganisa kanye Nobudlelwano Nomhlinzeki
Ekugcineni, ukuthola ukusebenza, okuthembekile ingxenye ye-iron ductile ayikona ukuthengwa kwewijethi. Ukusebenzisana okuncane. Imiphumela emihle kakhulu ivela ekubandakanyeni umsunguli kanye nochwepheshe bemishini kusenesikhathi. Bangakwazi yini ukuphakamisa ukuguqulwa kwe-engeli okusalungiswa kancane ukuze kuthuthukiswe ukugcwaliswa kwesikhunta? Ingabe ukungeza irediyasi encane ekhoneni kungaqeda ukukhuphuka kokucindezeleka kanye nekhanda elibuhlungu lemishini? Ingabe ukubekezelela okucacisiwe esicini esingabalulekile kushayela u-80% wezindleko zomshini?
Inkampani ehlinzeka ngesevisi eqondile egcwele, kusukela ekwenzeni iphethini (uma kudingeka) ukuya ekulingiseni kuye ekwenzeni imishini, njengalokho okubonayo I-Qingdao Qiangsenyuan Technology (QSY), inikeza iphuzu elilodwa lokuziphendulela. Umlando wabo weminyaka engu-30 ekulingiseni nasekukhiqizeni akuwona nje umugqa wokumaketha; iphakamisa ukuthi bazulazule kulezi zinkinga ngqo - ukuncipha, ukuhlanekezela, ukuguga kwamathuluzi, ukuqedwa - ezinkulungwaneni zama-oda. Bakhe izilawuli zenqubo nolwazi oluyimfihlo. Uma ubathumelela umdwebo wengxenye yensimbi eyinkimbinkimbi, bafunda phakathi kwemigqa, bacabanga ukuthi bangayenza kanjani ukuba i-castable, machable, futhi iqine, hhayi nje ukuthi icaphuna kanjani.
Ngakho-ke, uma ngicabanga ngezingxenye zemishini ye-iron ductile manje, angicabangi kakhulu mayelana nezakhiwo zencwadi yokufunda nokuningi mayelana nochungechunge lwezinqumo nezilawuli eziphendula into enhle ibe yingxenye enkulu. Ikhono lomsunguli, amapharamitha kanjiniyela, imininingwane kanjiniyela, konke kuqondaniswe. Impahla iyakwazi, kodwa ukusebenza kwayo ilethwa inqubo. Futhi leyo nqubo iyikho konke.
