Asinqamule umsindo. Uma abantu abaningi bezwa 'izingxenye zokulingisa amandla adonsela phansi', babona amawijethi e-aluminium angenasici, evolumu ephezulu ephuma emugqeni. Leyo yinguqulo yencwajana. Iqiniso eliphansi liwukuxoxisana okuqhubekayo phakathi kwenhloso yokuklama, ukuziphatha kwensimbi, kanye ne-physics enenkani yesikhunta esihlala njalo. Akukhona nje ukuthela insimbi emgodini wensimbi; ukulawula ukushisa, ukulindela ukuncipha ezindaweni ezingafanele, nokwazi lapho umklamo ucela iphutha.
Indawo Ephakathi Engaqondwa Kahle
I-gravity die casting ihlezi kulesi sikhala esithokozisayo, esivame ukusetshenziswa kabi phakathi kokulingisa isihlabathi nokuphonsa ngengcindezi ephezulu. Ngibona ama-specs engena ngaso sonke isikhathi lapho othile efuna ukuzinza kwe-dimensional kanye nokuqedwa okuhle kwesikhunta esihlala njalo, kodwa ngobunkimbinkimbi bangaphakathi bokubunjwa kwesihlabathi. Akusebenzi kanjalo. Insimbi idinga indlela ukuze igeleze futhi yondle. Awukwazi ukuba nezingxenye ezisindayo ezihlukanisiwe ngemuva kwezindonga ezincanyana - lokho kungumgodi wokuncipha olindele ukwenzeka. Isikhunta, ngokuba yinsimbi engagodli, ayithetheleli.
Lokhu sikufunde kanzima eminyakeni edlule kubakaki be-hydraulic manifold. Umdwebo weklayenti ubunomklamo omuhle, ohlangene onesikhwama esiqinile esincikene ne-flange elincanyana. Kubukeka kukuhle ku-CAD. Eqinisweni, i-lug yaqina ekugcineni, imunca insimbi engxenyeni encanyana evele isiqinile, ishiya ukuhlangana okunezimbotshana, okubuthakathaka. Ukulungisa kwakungekona nje ukulungisa ukuthela; kwakusho ukubuyela kumklami futhi wengeze ubambo olucashile ukuze lusebenze njengendlela yokuphakelayo. Yilokho usuku nosuku: ingxenye yobunjiniyela.
Lapha yilapho okuhlangenwe nakho kwe-Foundry enezinqubo ezihlukene kukhokha khona. Inkampani efana I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ngesizinda sabo segobolondo nokufaka utshalomali, empeleni banomlenze lapha phezulu. Baqonda amaphethini okuqinisa kusukela ekubunjweni okuyinkimbinkimbi. Ukusebenzisa lolo lwazi ku-gravity die casting kusho ukuthi abazona nje izigcwali zesikhunta; bacabanga ukuthi insimbi ihamba futhi iphole kanjani kusukela ekuhambeni. Ungabona indlela yabo ku-portal yabo ku- tsngtaocnc.com-kumayelana nenqubo efanele yengxenye, hhayi nje ukuthengisa ikhono elilodwa.
Okubalulekile Akukona Ukucabanga Kamuva
I-Aluminium ithola yonke inkazimulo, kodwa umdlalo ushintsha ngokuphelele namanye ama-alloys. Siyaxoxa izingxenye zokuphonsa amandla adonsela phansi ngethusi, noma ngisho nama-alloys athile e-magnesium. Ngamunye unedrama yawo. I-Aluminium A356? Uphethe ukuguqulwa kwe-strontium ye-silicon ye-eutectic futhi usebenza nokuthatha i-hydrogen. Thela kakhulu, futhi ubhake ku-porosity ngaphambi kokuba insimbi iqale ukupholisa.
Kodwa yithi udinga ingxenye ku-alloy esekwe ku-nickel yesevisi yezinga eliphezulu. Kungazelelwe, ukukhathala okushisayo kusikhunta sensimbi ye-H13 kuba indlela ebucayi. Ukushaqeka okushisayo okuvela ekutheleni ku-1500°C+ uma kuqhathaniswa ne-aluminium ku-700°C kunonya. Impilo yesikhunta iyawohloka. Imodeli yakho yezindleko iphuma ngefasitela. Kulapho ukukhuluma kwe-QSY yokusebenza ngama-alloys akhethekile afana ne-nickel-based akuyona nje iphoyinti lenhlamvu. Kusho ukuthi kudingeke ukuthi baxazulule lezi zinkinga zokuphatha okushisayo, mhlawumbe ngokusebenzisa isikhunta esikhethekile noma amasu okupholisa alawulwayo. Kuyiligi ehlukile ekukhipheni izindlu ze-aluminium.
Ngikhumbula iphrojekthi yendlu yezinzwa ngensimbi engagqwali eyi-duplex. Imininingwane yokugqwala ibiqinile. Inqubo ye-gravity die yasinika ukuphela kwendawo kanye nokuvumelana okudingekayo, kodwa ukulawula ibhalansi ye-ferrite-austenite ngokupholisa okulawulwayo kwesikhunta esihlala njalo kwakuyiphupho elibi. Sidlule kumaphrofayili omjikelezo oshisayo weshumi nambili esikhunjeni ngaphambi kokuba sithole i-microstructure engaguquki. Bekuyisikhumbuzo sokuthi i-'die' in gravity die casting iyithuluzi lokuphatha elishisayo njengethuluzi lokubumba.
I-Machining Handshake
Lona ukwakheka noma ikhefu abasunguli abaningi bomdlalo ohlanzekile abaphuthazayo. A amandla adonsela phansi ingxenye akuvamile ukuba umkhiqizo wokugcina. Kuyinto engenalutho ecishe ibe yi-net-shape eqonde ngqo ku-vise ye-CNC. Uma i-Foundry ingakuqondi ukwenza imishini, uthola izinhlobo ezimbili zekhanda elibuhlungu: izindawo ze-datum ezingahambisani ezilimaza ukulungiswa, noma izindawo eziqinile ezifihliwe ekupholiseni okungalingani okuphahlazeka kwamathuluzi.
I-synergy ibalulekile. Uma indlu yokulingisa iphinde isebenzise imigqa ye-CNC, njenge-QSY, kune-loop yempendulo. Umakhi wemishini utshela umsunguli ukuthi konke ukulingisa kwesithathu kunendawo eqinile ku-flange ethile. I-Foundry ibheka ukupholisa isikhunta futhi ibona umugqa owodwa wamanzi uvaleke kancane, udala indawo eshisayo yendawo kanye ne-microstructure eshintshiwe. Inkinga ixazululwe emthonjeni. Ngaphandle kwalokho kuhlanganiswa, kungumdlalo osolwayo phakathi komhlinzeki nesitolo somshini.
Siphikelela ekuhlolweni kwe-athikili yokuqala ehlanganisa isilingo somshini. Faka inqwaba, donsa isampula, futhi uyibeke emshinini wokugaya. Ingabe ibukeka ihlanzekile? Ingabe iwumshini ngokubikezela? Umbiko we-dimensional ovela ku-CMM uyinto eyodwa, kodwa umsindo womsiki nombala we-chip uxoxa indaba yangempela. I-gravity die casting enhle ayihlangani nje nokubekezelelwa kokuphrinta; Isebenza njengengxenye yezinto ezibonakalayo.
Lapho Kungahambi Kahle (Futhi Kuyoba)
Ukuhlaziywa kokwehluleka yilapho ufunda khona ngempela. Ngike ngabona izingxenye ze-X-ray kanye nokungena kodayi, bese zehluleka ekuhloleni ukukhathala. Ukuqhekeka njalo kuqala endaweni ebukeka ihlanzekile. Ngokuvamile, akulona iphutha elibi, kodwa ukugoqa okucashile kwe-oxide noma iqoqo elincane le-shrinkage elidalwe ngesikhathi sokugcwaliswa. Ngokuthululwa kwamandla adonsela phansi, uma isango lingalungile ukuze udale ukugeleza kwe-laminar, ugoqa esikhumbeni se-oxide ebusweni bomfudlana oncibilikisiwe. Iba i-crack initiator ephelele egqitshwe ngaphakathi odongeni.
Enye yakudala ukuhlanekezela. Udonsa ingxenye esikhunjeni, ibheka ku-CMM. Ngemuva kokwelashwa kokushisa (i-T6 ye-aluminium, yithi), iyajika. Izingcindezi eziyinsalela ezivela ekupholiseni okungalingani esikhunjeni esiqinile ziyakhululwa. Manje usabambekile ekuzameni ukuqondisa ingxenye ephethwe ukushisa, okuyindlela enhle yokwethula izingcindezi ezintsha. Isixazululo sivamise ukuba kumklamo wesikhunta—ukupholisa okulinganayo, ngezinye izikhathi ngisho nezindawo zamasu zokuhlukanisa ukuze kulingane ingaphambili lokuqinisa.
Lezi akuzona izinkinga zethiyori. Amahora achithwa ku-shakeout, ukunwaya ikhanda lakho, ukushintshanisa ama-thermocouples, nokulungisa izitsha zokuthulula. Umgomo inqubo eqinile, hhayi nje isampula enhle. Inani langempela lomphakeli lisendleleni abasingatha ngayo lezi zinkinga ezingagwemeki. Ingabe banokujula kwe-metallurgical kanye nenqubo yokuxilonga nokulungisa, noma bavele baphonsa enye inqwaba nethemba?
Ongokoqobo Isicelo Sweet Spot
Pho amandla adonsela phansi ashona kuphi ukukhanya ngempela? Okwezingxenye ezidinga ukuvumelana okungcono komshini kanye nokuqedwa kwendawo kunokusakazwa kwesihlabathi, ngamavolumu angathetheleli izindleko ezinkulu zamathuluzi zokusakaza ngengcindezi ephezulu. Cabanga ngamakhanda amasilinda, abakaki besakhiwo be-aerospace noma i-auto, izindlu zokumpompa lapho ikhwalithi yendawo yangaphakathi ibalulekile. Izingxenye lapho ungase ushicilele khona u-80% wezindawo ezingaphezulu, ngakho udinga indawo engaphansi engabikezelwa, eminyene.
Futhi ngeyabalingisi abakhulu, abasindayo. Ingcindezi ephezulu inemikhawulo kasayizi wokudutshulwa. Ngibone kahle kakhulu izingxenye zokuphonsa amandla adonsela phansi ngemishini yezimboni enesisindo esingaphezu kwama-50 kg. Awukwenzi lokho emshinini wegumbi elibandayo. Inqubo iyavumelana nezimo futhi ithuluzi, kuyilapho lingabizi, lingama-oda obukhulu obungaphansi kwesethi yokufa yokucindezela okuphezulu.
Uma ubheka iphothifoliyo efana ne-QSY's, esukela ekubunjweni kokutshalwa kwezimali okuyinkimbinkimbi kuye ekwenzeni imishini, kunengqondo. I-Gravity die casting ilingana ngqo kuleyo ndawo emaphakathi ezicini ezibucayi ngokwesakhiwo futhi ezidinga ukunemba okulandelayo. Kuyinqubo yobuchwepheshe, hhayi impahla. Umphumela, uma usuqedile ngalelo zinga lokugada okudidiyelwe, awuyona nje ingxenye. Kuyinto engenalutho eqinisekisiwe efakwe kusengaphambili evumela umklami alale ebusuku. Lokho okukhiphayo kwangempela, okungaphezu nje kokulingisa okungokoqobo ngokwako.
