Ukuchithwa kwesanti kuseyeyona nkqubo isetyenziswa kakhulu yokwenza isinyithi-ibalelwa ngaphezulu kwe-70% yazo zonke izinto eziveliswa kwihlabathi jikelele. Kodwa kubantu abatsha abangena kwi-Foundry, inani elipheleleyo le iindawo zokugalela isanti unokuziva ukongamela. Iipatheni, ukujamelana nokudonsa, i-sprues, ukuphakama, ii-cores, amasango-nganye idlala indima engenakuxoxisana nokuba i-casting ivela kwisandi okanye i-scrap.
Siye sabona uninzi lweenjineli zexesha lokuqala zingahambi kakuhle umgca wokwahlula ngexesha lokudityaniswa kokungunda. Sikhe sabukela amagcisa anamava akuhoyanga ukubekwa kwe-vent-kwaye ekugqibeleni sineepokotho zerhasi kwimizimba yevalvu yoxinzelelo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Apho sivelisa ukuchaneka kwentsimbi kunye neentsimbi zentsimbi yezindlu zempompo zoxinzelelo oluphezulu kunye nemilomo ye-cobalt-alloy, onke amacandelo okubumba kwesanti aqinisekisiwe-akucingelwanga. Makhe sihlolisise into ebalulekileyo iindawo zokugalela isanti, kungekhona njengeenkcazo zeencwadi zezifundo, kodwa njengezinto ezisebenzayo esizithembele kwimihla ngemihla ukuhambisa iinxalenye ezibambe i-350 + yoxinzelelo lwebar ngaphandle kokuvuza.
Izinto eziphambili ekufuneka uziqonde ngaphambi kokuba ugalele
Ukubunjwa kwesanti ayisosanti epakishwe nje. Yinkqubo eyilwe ngokuchanekileyo eyilelwe ukulawula ukuhamba kwesinyithi, ukondla ukuqina, kunye nokukhulula iigesi ezivalelekileyo. Nazi iindawo ezintlanu ezingenakuxoxisana-kwaye kwenzeka ntoni xa nabani na esilela:
- Umzekelo: Umfanekiso opheleleyo wenxalenye yokugqibela—edla ngokwenziwa ngomthi, iplastiki, okanye ialuminiyam eyenziwe ngoomatshini. Ukuchaneka kwayo kuchaza ngokuthe ngqo ukunyamezela kwe-dimensional. Sisebenzisa iipateni ze-aluminium ezenziwe nge-CNC kwizindlu ze-cylinder kuba zibamba ± 0.15 mm ngaphezu kwe-400 mm ubude-ibaluleke kakhulu xa umatshini wokutywina umphezulu we-post-cast.
- Cope kwaye utsale: Umphezulu (ukumelana) kunye nezantsi (ukutsala) iziqingatha zokungunda. Ujongano lwabo ngumgca wokwahlulahlula. Ukungalungelelanisi apha kudala i-flash ekufuneka icocwe-inyathelo elibizayo lokuphinda siphephe ngokusebenzisa ukubhaliswa kwe-dowel-pin kuzo zonke iimolds zemveliso.
- Sprue: Umjelo othe nkqo apho isinyithi esinyibilikisiweyo singena kumgodi wokungunda. Emxinwa kakhulu? I-Turbulence inyusa ukubunjwa kwe-oxide. Ibanzi kakhulu? Ukondla kakubi. Kwiindawo zethu zempompo ye-cobalt ye-T800 ye-cobalt, silinganisa i-sprues ngokusekelwe kwizibalo zentloko ye-metallostatic-hayi iitshathi zomgaqo-obhontsi.
- Umphakamisi: Indawo yokugcina amanzi ebekwe ngaphezulu okanye ecaleni kwendawo yokugalela ukondla ukuncipha ngexesha lokuqina. Impazamo eqhelekileyo: ukuthoba izinyusi kwiindawo ezishinyeneyo. Kwi-batch enye yezindlu ze-piston pump cylinder, umthamo onganeleyo wokunyuka ubangele i-centerline porosity-ifunyenwe kuphela ngexesha lokuhlolwa kwe-ultrasonic. Ngoku silinganisa ukuqina kunye ne-MAGMAsoft ngaphambi kokwenziwa kokubumba.
- Undoqo: Indawo eyahlukileyo yesanti eyenza imingxuma yangaphakathi—njengeepaseji zokupholisa okanye iibhobho zevalvu. Iicores kufuneka zimelane noxinzelelo lwe-metallostatic kunye nokuphazamiseka kwe-thermal. Sisebenzisa isanti ye-silica ebophelelwe ngamakhemikhali kunye ne-furan resin ukuze sibe namandla angundoqo, uze ubhake kwi-220 ° C imizuzu engama-90. Iintsimbi ezingabhakwanga ziwa phantsi kwe-1,450°C yentsimbi etyhidiweyo.
Kutheni uYilo lweSango lwahlula iiCastings ezithembekileyo kwi-Scrap
Amasango-imijelo edibanisa i-sprue kwi-cavity-ayifane ixoxwe, kodwa imisela ukunyaniseka komphezulu, ukwakhiwa kweenkozo, kunye nokusabalalisa okubandakanya. Abanye banokuphikisa ukuba indawo yesango yeyesibini kuyilo lwepateni. Nangona kunjalo, kumava ethu nge-AMS 5387 cobalt alloy 6 components, ukungena ngendlela engafanelekanga kubangela ukungaphumeleli okuphindwe kathathu: ukuvalwa okubandayo kufutshane neendonga ezicekethekileyo, ukukhukuliseka kwesanti kwiindawo ezinesantya esiphezulu, kunye nokubanjwa kwenkunkuma kwiindawo zokungena emgodini.
Sisebenzisa isango elisezantsi kwizindlu ezinde, ezinodonga olucekethekileyo ukunciphisa isiphithiphithi. Kwiindawo ezilinganayo ezifana ne-winch center shaft rollers, sisebenzisa amasango amaninzi e-radial-ukuqinisekisa ukuzaliswa okufanayo kunye nokuqina kwesikhokelo ukuya kwizinyusi. Isango ngalinye elinqamlezayo libalwa kusetyenziswa umgaqo kaBernoulli olungiselelwe i-viscosity yensimbi kunye nokuhla kweqondo lokushisa. Leyo ayiyiyo ingcamango-yindlela esiyifumana ngayo i-Cpk> 1.33 kwii-diameter ezibalulekileyo kwi-500 + yokuvelisa imveliso.
Yintoni ejongwa ngabaqalayo: iiVents, isanti yokuhlukanisa, kunye nexesha le-Shakeout
Imingxunya yimingxuma emincinane—ekholisa ukuba yi-1–2 mm ubukhulu—egrunjwa kwicope okanye irhuqe ukuze kuphume umoya kunye neegesi zokungunda. Zitsibe, kwaye ufumana imingxunya okanye imingxunya. Sifaka ama-vents ngesandla emva kokuhlanganiswa kwesikhunta, sibeka kwiindawo zokugqibela zokugcwalisa ezichongiweyo ekufaniseni. Akukho nto i-automation-kuba isixhobo sokunxiba sitshintsha umngxuma wejometri, kunye nokungahambelani kwe-venting kuyonakalisa i-microstructure.
Isanti esahlulayo—umaleko ocolekileyo ovuthululweyo phakathi kwecope kunye ne-drag-mayomile, ikhululekile, kwaye ingadibanisi. Sisebenzisa umgubo we-alumina we-calcined, hayi igraphite. I-graphite ifaka ukufuma kwi-mold interface kwaye ikhuthaza iziphene ze-veining kwi-castings yensimbi engenasici.
Ixesha le-Shakeout libaluleke kakhulu kunokuba uninzi lucinga. Ukususa i-castings kwangethuba kakhulu kubangela ukuqhekeka kwe-thermal-ingakumbi kwi-high-carbon iron. Kade kade, kwaye ubushushu obushiyekileyo bubangela ukugqwetheka kwiindawo zesalathiso ezinomatshini. Umgangatho wethu: i-air-cool castings de ubushushu bomhlaba buwele ngaphantsi kwe-150 ° C, iqinisekiswe ngee-thermometers ze-IR eziphathwa ngesandla-kungekhona izibali-xesha.
Ukusuka kwiMold ukuya kwiMishini-Icandelo eliBalulekileyo: Apho iSand Casting ingena khona namhlanje
Ukuchithwa kwesanti akusiyo iteknoloji yefa-yisiseko sokuveliswa kwe-hybrid. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY, sidibanisa izikhala zesanti kunye ne-multi-axis CNC machining, unyango lobushushu, kunye nokugqiba umphezulu-konke phantsi kophahla olulodwa oluhambelana ne-ISO. Olo lawulo oluthe nkqo lusenza siqinisekise ukuthotyelwa kwe-GD&T kwiimpawu ezinjengokugxila kwe-bore-to-flange (±0.05 mm) okanye uburhabaxa bomphezulu i-Ra ≤0.8 µm ebusweni bokutywina.
Ukuba ukhankanya indlu yevalve yoxinzelelo okanye icandelo lemoto yobunjineli, ukuqonda iindawo zokugalela isanti kuthetha ukwazi ukuba unyamezelwano luhlala phi, iziphene ziqala phi, kunye nendlela ukhetho loyilo oluchaphazela ngayo iindleko kunye nexesha lokukhokela. Kuthetha ukubuza ukuba "Ngaba ingaphoswa?" kodwa “ilungu ngalinye lokungunda liya kuziphatha njani kwi-1,520°C kunye nexesha lokugalelwa kwemizuzwana eli-12?”
Lowo ngumahluko phakathi komzobo kunye nokuhanjiswa. Yiyo loo nto abathengi bethu-ukusuka kuMntla Melika ukuya kuMzantsi-mpuma Asia-sithumelela imizobo etyebileyo ye-GD&T eneempawu eziqinileyo zetsimbi, hayi imizobo nje. Kuba bayazi ukuba isikhunta ayisositya nje. Linqanaba lokuqala lokulawula umgangatho.
