Xa usiva 'ilahleko yesanti yokuphosa', uninzi lucinga ngobucwebe obuntsonkothileyo okanye amaqhekeza obugcisa. Ngumgibe oqhelekileyo lowo. Kwiimeko zemizi-mveliso, ngakumbi kwizinto ezintsonkothileyo, ezinomthamo ophantsi ukuya kwephakathi, lirhamncwa elahlukileyo ngokupheleleyo. Akunjalo nje ngokwenza isikhunta; imalunga nokulawula umtshato phakathi kwepateni echanekileyo yewax kunye nokungunda kwesanti eyomelelayo, ukwazi ngqo apho inkqubo iya kulwa nawe, kunye nokuba ne-machining backup yokucoca ubumdaka obushiya ngasemva.
Ukubhideka okuNgqondo: Ayilulo uTyalo-mali olusulungekileyo
Abantu bahlala beyigalela phantsi 'kokutyalo-mali'. Kodwa utyalo-mali oluyinyani lusebenzisa iqokobhe leceramic. Ukugalelwa kwesanti elahlekileyo ngumzala wayo orhabaxa, othanda izinto. Usaqala nge-wax okanye ipateni enyibilikayo-leyo yindawo 'elahlekileyo'. Kodwa endaweni yokwakha i-ceramic layers, upakisha loo pateni kwiflask yesanti, ehlala usebenzisa isanti ebotshiweyo. Unyibilikisa iwax ngaphandle, ugalela isinyithi ngaphakathi. Umphezulu ogqityiweyo awusayi kuba njengeglasi njengeqokobhe leceramic, kodwa kwiindawo ezininzi ezisebenzayo, ingakumbi ezinkulu, yindawo eswiti eyongayo. Ucelomngeni kukulawula ukuziphatha kwesanti ngexesha lokudinwa nokugalelwa.
Apho ubona khona umahluko kukuyilo. Kwiqokobhe leceramic, unokuhamba kunye nee-engile zedrafti ezikufutshane-zero kwiipateni. Ngesanti, udinga ngakumbi. Akuninzi, kodwa ngokwaneleyo ukuvumela isanti ukuba ihlangane ngokufanelekileyo kwaye ikhulule ngaphandle kokukrazula. Ndibone iiprojekthi zisilela ngenxa yokuba umyili, osetyenziselwa ukutyala imali, wathumela ipateni eneendonga ezithe nkqo zenkqubo yesanti. Iicores zawa. Ibiyingxubakaxaka. Kufuneka uyile i-mold medium.
Apha kulapho amava evenkile ayinto yonke. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), kumashumi amathathu eminyaka abo ekusaseni nasematshinini, kusenokwenzeka ukuba bakubonile oku kuphindaphindwa koku. Badwelisa zombini ukungunda kweqokobhe (elinye igama le-ceramic investment casting) kunye nokuphosa utyalo-mali ngokwahlukeneyo kwindawo yabo https://www.tsingtaocnc.com, endixelela ukuba bayawuqonda umahluko. Xa usebenza nge-alloys ezikhethekileyo-esekelwe kwi-nickel, i-cobalt-esekelwe-ukuba ulwahlulo lubaluleke ngakumbi. Inkqubo yokungena kwi-superalloy kwi-mold yesanti ngokuchasene neqokobhe le-ceramic lihlabathi elihlukeneyo malunga nokutshatyalaliswa kobushushu kunye nokubanakho ukubandakanywa.
Isanti Ngokwayo: Ngakumbi kunobumdaka nje
'Intlabathi' esegameni iyalahlekisa. Asiyosanti yebala lokudlala. Ngokuqhelekileyo i-silica okanye isanti ye-zircon, ehlanganiswe ne-resin binder-ngokuqhelekileyo i-phenolic okanye inkqubo ye-furan. Umlinganiselo, ixesha lokuxuba, ubushushu bokunyanga; asizizo iinguqu, yimithetho. Yenza umxube ungalunganga, kwaye amandla akho okubumba acimile. Ibuthathaka kakhulu, iyaqhekeka ngexesha lokugalela. Inamandla kakhulu, ayivumeli ukuncipha kwesinyithi esifanelekileyo, okukhokelela kwiinyembezi ezishushu ekuzikhupheni ngokwazo.
Oku sikufunde kabuhlungu kwibhetshi yemizimba yevalvu yentsimbi. Isanti yayinyangekile ngokugqithisileyo. I-castings yaphuma ibonakala ilungile, kodwa uvavanyo lwe-ultrasonic luveze iwebhu yee-micro-cracks kufutshane namaziko ashushu. Umngundo wawuqina kakhulu, ulwa nentsimbi njengoko uphola. Kwafuneka sikhuphe yonke into. Ukulungiswa kwakungekho nzima-ukulungelelanisa nje umjikelo wonyango-kodwa ukwazi ukuba ulungelelanise ntoni ukusuka kwiminyaka yokudibanisa iindlela zokungaphumeleli ukubuyisela iiparameters.
Enye i-nuance kukubuyiselwa kwesanti. Awunakuphinda uyisebenzise ngokungenasiphelo. Isibophelelo siyaphuka, izohlwayo ziyaqokelelana. I-Foundry elungileyo ibeka iliso kwi-LOI (Ilahleko kwi-Ignition) yesanti yabo ebuyisiweyo. Ndingathanda ukubona ukuba umsebenzi okudala umile onje nge-QSY ulawula njani umjikelo wabo wesanti, ngakumbi xa betshintsha phakathi kwemathiriyeli efana nentsimbi ekhandiweyo kunye ne-nickel alloys. Ungcoliseko olunqamlezayo lwesanti ukusuka kusapho lwealloyi ukuya kwenye lunokwazisa izinto ezitshabalalisa isinyithi.
Ipateni yeWax: Apho uLawulo oluMdaniso luqala khona (kwaye luphela)
Yonke into ixhomekeke kwipateni. Kuba ukulahlwa kwesanti elahlekileyo, usebenzisa iwax ethambileyo, esezantsi-enyibilikayo kunomsebenzi weqokobhe leceramic. Kufuneka iqine ngokwaneleyo ukuze ikwazi ukuphatha isanti ramming kodwa ithambe ngokwaneleyo ukuze inyibilike ngokucocekileyo ngaphandle kwentsalela. Intsalela ngumbulali. Nayiphi na i-carbonaceous gunk eseleyo kwi-wax iya kudala iziphene zegesi ekugaleleni.
Iiparamitha zokutofa kumbandela we-wax ngaphezu kokuba uninzi lucinga. Uxinzelelo, ubushushu, kunye nexesha lokubamba kuchaphazela ukushwabana kwe-wax kunye nomgangatho womphezulu. Umphezulu otshone kancinci kwi-wax unokubonakala ungabalulekanga, kodwa uguqulela ngokuthe ngqo kwindawo ebhityileyo eludongeni lwentsimbi lokugqibela. Sakha saba nesiphene kwimpompo yendlu—ehlala ikwindawo eflethi. Kusithathe iiveki ukuyilandelela emva kwinaliti yewax yokupholisa ngokulinganayo. Ipateni ye-wax yayigqwesa njengoko ipholile, kodwa yayifihlakeleyo ungayibona kuphela nge-jig check.
Yiyo loo nto udibaniso kunye ne-machining, njengeenkonzo ze-CNC ezinikezelwa yi-QSY, ayinakuxoxisana. Awufane ufumane ukuphoswa kobume bomnatha kule nkqubo, ngakumbi ngeejometri ezintsonkothileyo. Isixhobo sepateni sinxiba, isanti iyatshintsha ngomzuzu. Inxalenye ye-as-cast sisitokhwe sakho esirhabaxa. Inqanaba lomatshini we-CNC kulapho ubetha khona imilinganiselo yokugqibela kunye nokunyamezelana. Ngumdlalo onezinto ezimbini: ukuphosa kukufumana i-95% apho, ubugcisa buzisa i-5% yokugqibela ngokuchanekileyo.
Ukugada kunye nokutyisa: Ubunjineli obungabonakaliyo
Lo ngumsebenzi omnyama we-Foundry work. Ukugalela isinyithi esinyibilikisiweyo kwisingundo sesanti akufani nokuzalisa i-emele. Udinga inkqubo-abagijimi, amasango, ukunyuka-ukulawula ukuhamba kunye nokunciphisa ukutya njengoko isinyithi siqina. Kuba ukulahlwa kwesanti elahlekileyo, le nkqubo isoloko yakhelwe kwindibano yepateni yewax ngokwayo. Iipateni ezininzi zewax zincanyathiselwe 'kumthi' osembindini owenza ikomityi yokugalela kunye neembaleki.
Ukuyila lo mthi ngamava acocekileyo. Beka isikhuphukeli kwindawo engafanelekanga, kwaye udala i-hotspot ye-thermal ekhuthaza ngokwenene i-shrinkage porosity. Sebenzisa isango elincinane kakhulu, ufumana ukubaleka kwenkungu kunye nokuvalwa okubandayo. Inkulu kakhulu, kwaye udala isiphithiphithi esigqithisa isanti kunye ne-slag. Ndikhumbula iprojekthi yokufakwa kwebronzi yodidi lwaselwandle apho sasihlala sifumana ukufakwa kwesanti. Sitshintshe ubushushu bokuthulula, sahluza isinyithi, akukho nto yasebenza. Ekugqibeleni, umenzi wepateni yakudala wayijonga waza wathi isango lalingena kumngxuma wokungunda likwi-engile ethe kratya, libangela ukuba isinyithi sijike kwaye sikhukulise udonga lwesanti. Wayenyanisile. Utshintsho olulula kwisakhiwo sendibano ye-wax yasombulula.
Eli nqanaba lokusombulula ingxaki yinto onokuyilindela kwingcali. Ukujonga izinto ezisebenza nge-QSY kunye-ezingenasici, i-alloys ezikhethekileyo-uyilo lokungena lubaluleke ngakumbi. Ezi alloys zinee-fluidity ezahlukeneyo kunye neepateni zokuqinisa kune-carbon steel plain. Uyilo lwesango olusebenzela intsimbi etyhidiweyo lunokubangela ukuqhekeka kwi-alloy esekwe nickel. Asiyonkqubo yobukhulu obunye.
Kutheni kusabalulekile kwiLizwe le-CNC
Ngoomatshini bale mihla be-CNC be-5-axis, unokubuza ukuba kutheni uzikhathaza ngokuphosa konke? Kutheni ungasebenzisi nje umatshini osuka kwibha eqinileyo? Kwiprototypes enye, mhlawumbi. Kodwa kwimveliso iqhuba nokuba ngamaqhekeza angama-50-100, ukulahlwa kwesanti elahlekileyo iphumelele kwizinto eziphathekayo kunye neendleko, ngakumbi ngee-alloys ezibizayo. Ubeka isinyithi kuphela apho ifuneka khona, hayi ukwenza ama-70% exabiso le-nickel alloy billet. Umba okufutshane-netha awugcini nje izinto eziphathekayo, kodwa ubuninzi bexesha lomatshini.
Ikwavumela iijiyometri ezingenzekiyo okanye ezingenzekiyo ngomatshini wodwa. Iindidi zangaphakathi, i-undercuts, iindawo ezinzima ezigobileyo-ezi zinokuthi zenziwe ngokuthe ngqo ngumbumba. Umsebenzi olandelayo we-CNC ke ngowobuso obuchanekileyo, imisonto, kunye nemiphezulu yokukhwelana. Yifilosofi yokuvelisa umxube. Inkampani enikezela zombini ukuphosa kunye nomatshini phantsi kophahla olunye, njengoko i-QSY isenza, iyayiqonda le synergy ngaphakathi. Banokwandisa uyilo lwenxalenye yalo lonke uhambo lokuvelisa, hayi nje inqanaba elinye.
Uvavanyo lwangempela kukulungiswa kwamalungu amadala okanye aphelelwe lixesha. Ukubuyisela umva ubunjineli inxalenye eyaphukileyo, ukudala ipateni ye-wax evela kwi-3D scan okanye inxalenye endala, kunye nokuqhuba ibhetshi encinci ngokuphosa kwesanti elahlekileyo kudla ngokuba sisisombululo esisebenzayo. Igcina izixhobo zelifa zisebenza. Esi sisicelo esisebenzayo, esingathandekiyo, kodwa esibaluleke kakhulu kule nkqubo yesikolo esidala. Akunjalo malunga ne-automation ephezulu yevolumu; imalunga bhetyebhetye, ukusebenza ngesinyithi abanezakhono. Kwaye, ndiyakrokrela, yeyona nto ithe yagcina imisebenzi kumashumi eminyaka yotshintsho lweshishini.
