Masiyinqumle loo ngxolo. Xa uninzi lwabantu lusiva 'inxalenye yokuphosa i-gravity die die casting', bafanekisela iiwijethi zealuminiyam ezingenasiphako, ezinomthamo omkhulu ziqengqeleka emgceni. Leyo yinguqulelo yencwadana. Inyani emgangathweni luthethathethwano oluqhubekayo phakathi kwenjongo yoyilo, ukuziphatha kwentsimbi, kunye nefiziksi enenkani yokungunda okusisigxina. Ayikokugalela nje isinyithi kumngxuma wentsimbi; kukulawula ubushushu, ukulindela ukushwabana kwiindawo ezingafanelekanga, nokwazi xa uyilo lufuna isiphene.
UMbindi Ongaqondwayo
I-Gravity die casting ihleli kule ndawo inika umdla, ehlala isetyenziswa gwenxa phakathi kokulahlwa kwesanti kunye noxinzelelo oluphezulu lokuphosa ukufa. Ndibona i-specs ingena ngalo lonke ixesha apho umntu efuna ukuzinza komda kunye nokugqitywa kakuhle kokungunda okusisigxina, kodwa kunye nobunzima bangaphakathi bokuphosa isanti. Ayisebenzi ngolo hlobo. Isinyithi sifuna indlela yokuhamba kunye nokutya. Awunakukwazi ukuba namacandelo anzima ahlukeneyo emva kweendonga ezincinci-leyo yi-shrinkage cavity elindele ukuba yenzeke. Ukungunda, ukuba yintsimbi engapheliyo, akuxoleli.
Oku sikufunde kabuhlungu kwiminyaka eyadlulayo kwisibiyeli se-hydraulic manifold. Umzobo womthengi wawunoyilo oluhle, olubambeneyo kunye nengxowa eshinyeneyo exhonywe ecaleni kweflange encinci. Ijongeka kakuhle kwiCAD. Enyanisweni, i-lug yaqina ekugqibeleni, ifunxa isinyithi ukusuka kwindawo esele iqinile, ishiya i-porous, i-junction ebuthathaka. Ulungiso lwalungekokulungisa nje ukugalela; kwakuthetha ukubuyela kumyili kunye nokongeza ubambo olufihlakeleyo ukuze usebenze njengendlela yokutya. Nantso imihla ngemihla: inxalenye yobunjineli.
Kulapho amava e-Foundry eneenkqubo ezahlukeneyo ahlawula khona. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye nemvelaphi yabo kwiqokobhe kunye nokuphosa utyalo-mali, eneneni inomlenze apha phezulu. Baqonda iipateni zokuqiniswa ukusuka kwi-castings entsonkothileyo. Ukusebenzisa olo lwazi kumxhuzulane kwi-die casting kuthetha ukuba asingabo nje abazalisi bokungunda; bacinga ngendlela intsimbi ehamba ngayo kwaye iphole ukusuka ekuqaleni. Ungayibona indlela yabo kwi-portal yabo tsngtaocnc.com—imalunga nenkqubo eyiyo yecandelo, hayi ukuthengisa nje isakhono esinye.
Izinto eziphathekayo asiyongcinga esemva
I-aluminium ifumana lonke uzuko, kodwa umdlalo utshintsha ngokupheleleyo kunye nezinye i-alloys. Siyathetha umxhuzulane kufa iindawo zokuphosa ngobhedu, okanye iialloys ezithile ze-magnesium. Nganye inedrama yayo. Aluminiyam A356? Ulawula ukuguqulwa kwe-strontium ye-silicon ye-eutectic kwaye ujongana ne-hydrogen pickup. Galela ngokukhawuleza kakhulu, kwaye ubhaka kwi-porosity ngaphambi kokuba isinyithi siqale ukupholisa.
Kodwa yithi ufuna inxalenye kwi-alloy esekwe kwi-nickel yenkonzo yobushushu obuphezulu. Ngokukhawuleza, ukukhathala kwe-thermal kwi-mold yensimbi ye-H13 iba yindlela ebalulekileyo. Ukutshatyalaliswa kwe-thermal ekugaleleni kwi-1500 ° C + kunye ne-aluminium kwi-700 ° C yinkohlakalo. Ubomi bokungunda buyehla. Imodeli yakho yeendleko iphuma ngefestile. Kulapho ukukhankanywa kwe-QSY yokusebenza kunye ne-alloys ezikhethekileyo ezifana ne-nickel-based based akuyona nje i-bullet point. Oku kuthetha ukuba kuye kwafuneka basombulule le miba yolawulo lobushushu, mhlawumbi ngokusebenzisa imixokozeko ekhethekileyo okanye iindlela ezilawulwayo zejelo lokupholisa. Yiligi eyahlukileyo ekuvuthululeni izindlu ze-aluminiyam.
Ndikhumbula iprojekthi ye-sensor yezindlu kwi-duplex steel stainless. Iimpawu zomhlwa beziqinile. Inkqubo yokufa komxhuzulane yasinika ukugqitywa komphezulu kunye nokungaguquguquki okufunekayo, kodwa ukulawula ibhalansi ye-ferrite-austenite ngokupholisa okulawulwayo kokungunda okusisigxina yayiliphupha elibi. Sidlule kwishumi elinesibini leprofayili yomjikelo we-thermal kwi-mold ngaphambi kokuba sifumane i-microstructure engaguqukiyo. Yayisisikhumbuzo sokuba 'i-die' kwi-gravity die casting sisixhobo solawulo lwe-thermal njengesixhobo sokubumba.
Ukuxhawula ngesandla ngoMachining
Esi sisenzo okanye ikhefu abathi abaqambi abaninzi bomdlalo osulungekileyo baphuthaphuthayo. A umxhuzulane die cast inxalenye kunqabile isiphelo-mveliso. Yimilo ekufutshane-netha-engenanto ethe ngqo kwi-vise ye-CNC. Ukuba i-Foundry ayibuqondi ubuchwephesha, ufumana iintlobo ezimbini zeentloko ezibuhlungu: umphezulu wedatum ongahambelaniyo owonakalisa ukulungiswa, okanye iindawo ezinzima ezifihlakeleyo zokupholisa okungalinganiyo okophula izixhobo.
I-synergy ibalulekile. Xa indlu yokuphosa ikwaqhuba imigca ye-CNC, njenge-QSY yenza, kukho i-loop yempendulo. Umchwephesha uxelela i-Foundry ukuba i-casting nganye yesithathu inendawo enzima kwi-flange ethile. I-Foundry ijonge ukupholisa ngundo kwaye iyaqonda ukuba umgca omnye wamanzi uvalekile ngokuyinxenye, udala indawo eshushu yendawo kunye ne-microstructure etshintshiweyo. Ingxaki isonjululwe kumthombo. Ngaphandle koko kudityaniswa, ngumdlalo otyholayo phakathi komthengisi kunye nevenkile yomatshini.
Sigxininisa ekuhlolweni kwenqaku lokuqala elibandakanya ukuvavanywa komatshini. Yenza ibhetshi, tsala isampuli, kwaye uyibeke kwilitye lokusila. Ngaba ilungiswa ngokucocekileyo? Ngaba imatshini iyaqikelelwa? Ingxelo ye-dimensional evela kwi-CMM yinto enye, kodwa isandi somsiki kunye nombala we-chip uxela ibali lokwenyani. A gravity elungileyo die casting ayihlanganisi nje ukunyamezela ushicilelo; Isebenza ngoomatshini njengento eqikelelwayo.
Xa ingahambi kakuhle (kwaye iya)
Uhlalutyo lokungaphumeleli kulapho ufunda khona ngokwenene. Ndikhe ndabona iindawo zidlula i-X-reyi kunye nedayi yokungena, emva koko basilele kuvavanyo lokudinwa. Ukuqhekeka kuhlala kuqala kwindawo ebonakala icocekile. Ngokuqhelekileyo, ayisosiphene esibi, kodwa i-oxide efihlakeleyo okanye i-micro-shrinkage cluster eyenziwe ngexesha lokuzaliswa. Ngokugalela umxhuzulane, ukuba isango lokungena alilunganga ukwenza ukuqukuqela kwe-laminar, usonga eluswini lweoxide ukusuka kumphezulu womlambo otyhidiweyo. Iba ngumqalisi wokuqhekeka ogqibeleleyo ongcwatywe ngaphakathi eludongeni.
Enye iklasikhi kukugqwesa. Utsala inxalenye kwi-mold, ihlola kwi-CMM. Emva kokunyanga ubushushu (i-T6 ye-aluminium, yithi), iyajika. Uxinzelelo olushiyekileyo lokupholisa okungalinganiyo kwisingundo esiqinileyo luyakhululwa. Ngoku ubambekile ekuzameni ukulungisa indawo ephethwe bubushushu, eyindlela entle yokwazisa uxinzelelo olutsha. Isisombululo siqhelekile kuyilo lokungunda-ukupholisa okulinganayo, ngamanye amaxesha nakwiindawo ezicwangcisiweyo zokugquma ukulinganisa umphambili wokuqina.
Ezi ayizongxaki zethiyori. Ziiyure ezichithwe kwi-shakeout, ukukrwela intloko, ukutshintshisa ii-thermocouples, kunye nokuthulula izitya zokugalela. Injongo yinkqubo eyomeleleyo, kungekhona nje isampuli elungileyo. Ixabiso lokwenene lomthengisi likwindlela abasingatha ngayo ezi ngxaki zingenakuthintelwa. Ngaba banabo ubunzulu be-metallurgical kunye nenkqubo yokuxilonga kunye nokulungisa, okanye ngaba baphosa enye ibhetshi kunye nethemba?
I-Reality Application Spot Spot
Ke phi umxhuzulane die casting kukhanya ngokwenene? Yeyamalungu afuna ulungelelwaniso olungcono loomatshini kunye nokugqitywa komphezulu kunokuphosa isanti, ngokwemithamo engathethelela indleko enkulu yezixhobo zoxinzelelo oluphezulu. Cinga iintloko ze-cylinder, izibiyeli zesakhiwo se-aerospace okanye i-auto, izindlu zempompo apho umgangatho wangaphakathi ubalulekile. Amacandelo apho unomatshini wama-80% wemigangatho, ngoko udinga i-substrate eqikelelwayo, exineneyo.
Ikwazezinkulu, iicastings ezinzima. Uxinzelelo oluphezulu lunemida yobungakanani bokudubula. Ndibone kakuhle umxhuzulane kufa iindawo zokuphosa koomatshini boshishino abanobunzima obungaphezulu kwama-50 kg. Awuyenzi loo nto kumatshini wegumbi elibandayo. Inkqubo iyaguquguquka kwaye izixhobo, ngelixa zingabizi, ziodolo zobukhulu obungaphantsi koxinzelelo oluphezulu lokufa.
Ukujonga ipotifoliyo efana ne-QSY's, esuka kwi-investment castings yotyalo-mali ukuya kwi-machining, iyavakala. Umxhuzulane wokujula ulingana kanye kuloo zowuni ephakathi kumacandelo abaluleke kakhulu ngokwesakhiwo kwaye afuna ukwenziwa ngobuchule obulandelayo. Yinkqubo yobugcisa, hayi imveliso. Isiphumo sokugqibela, xa sisenziwa ngelo nqanaba lolongamelo oluhlanganisiweyo, asiyonxalenye nje. Yindawo engenanto eqinisekisiweyo eyenziwe kwangaphambili eyenza umyili alale ebusuku. Leyo yimveliso yokwenyani, ngaphezu kokuphoswa ngokwako ngokwako.
