ukukhiqizwa kwesihlabathi

Ukukhiqizwa kwesihlabathi kusalokhu kuyindlela engabizi kakhulu yokukhiqiza izingxenye zensimbi eziyinkimbinkimbi, ezinobuqotho obuphezulu—ikakhulukazi lapho ukujiya kodonga kudlula u-6 mm, ingxenye yesisindo idlula u-5 kg, noma imiqulu yonyaka iwela phakathi kwamayunithi ayi-10 no-500. Kodwa akukona konke ukubunjwa kwesihlabathi okulinganayo. Sibone amakhasimende amaningi kakhulu ethola ukulingwa okunesakhiwo sokusanhlamvu esingahambelani, ukushwabana okungalindelekile kumaflange athwalayo, noma ukukhukhuleka okunohlangothi ngemva kokwelashwa okushisayo—ukuthola kuphela ukuthi imbangela yayingelona izinga elibonakalayo noma izinga lokushisa eliyisisekelo, kodwa ukuminyana kwesikhunta kuhlukahlukana kuwo wonke amaphrinta ayinhloko.

Kungani Ukusakazwa Kwesanti Kusawina Ngezingxenye Zezimboni Ezinembile

Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sisebenzisa imigqa yokusakaza isihlabathi neyotshalomali—kodwa sigodla ukufakwa kwesihlabathi ezingxenyeni lapho ubukhulu be-thermal, ukumanziswa komshini, noma i-geometry enkulu ikufuna khona: isilinda sepompo ye-piston sinobude obufika ku-1,200 mm, iwintshi yemoto yonjiniyela isikhungo se-shaft roller enesisindo esingu-2 kg2. Lezi akuzona "izikhala ezingenalutho" ezilindele ukwenziwa kwemishini enzima. Ziyizinto ezilingiswayo ezinomumo we-net-net obanjwe ku-±0.3 mm ezindaweni ezibucayi zedatha, nokuqedwa okungaphezulu kuqine njengo-Ra 6.3 µm ezindaweni zokusebenzelana ngomshini.

Ukhiye aweqi ukunemba—ukushumeka kusenesikhathi. Inqubo yethu yokukhiqiza isihlabathi iqala ngokusetshenziswa kwephethini eyenziwe ngomshini we-CNC (hhayi ukhuni noma igwebu), isebenzisa isihlabathi se-silica esihlanganiswe ne-resin esinomswakama olawulwayo. <2.1% nokuvunyeleka okungu-110–130, futhi kusetshenziswa ukuqapha kokuminyanisa kwesikhathi sangempela ngesikhathi sokubumba. Leso sinyathelo sokugcina sisodwa sinciphisa amaphutha amakhulu okushintsha ngo-74% uma kuqhathaniswa ne-ramming eyenziwa ngesandla—idatha eqinisekiswa kuwo wonke ama-hydraulic manifold batches angu-18 ngaphezulu kwe-Q3 2023.

Izinqumo Ezine Zezobuchwepheshe Ezenza noma Ephule Ukusakaza Kwakho

Ukwehluleka okuningi kubuyela emuva kokunye kwezine izinqumo ezenziwe ngaphambi kokuba uhlamvu lokuqala lwesihlabathi luthinte iflaski:

• Isu lemvume yephethini: Isinxephezelo esijwayelekile esingu-1% sokuncipha siyehluleka kuma-cobalt-nickel alloys afana ne-AMS 5387. Sisebenzisa izibonelelo ezihlukene—0.92% axial, 0.85% radial—kuzindlu zephampu ezisekelwe ku-T800 ukubamba ama-callout e-GD&T kumajenali anezinhlamvu.
• I-Riser design logic: Akususelwe kwivolumu, kodwa ukuqiniswa-kuhambisana nesikhathi. Silingisa amajika okupholisa sisebenzisa i-MAGMAsoft, bese sibeka izikhuphukeli ezingavalekile kuphela lapho isikhathi sokuqina sasendaweni sehla ngaphansi kwama-87% wesisekelo sesigaba esiwugqinsi.
• Ukufakwa kokukhipha umoya kwesikhunta: Ama-vents ahamba ngo-12 mm ukusuka emigqeni ehlukanisayo ye-cope/core—hhayi ngokungahleliwe—eqondaniswe ukuze abaleke ezindleleni zokugeleza kwegesi eziklanywe ngokuhlolwa kokubola kwe-vacuum.
• Isikhathi se-Shakeout: Ungalokothi “uma upholile ngokwanele ukubamba.” Ngokusakazwa kwensimbi eyi-ductile ngaphezu kogqinsi kwengxenye engu-80 mm, sibambezela ukunyakaziswa kuze kufike izinga lokushisa elingaphezulu kuka-520°C ±15°C. Chezuka ngaphezu kuka-20°C, futhi ukucindezeleka okusalayo kukhuphuke ngo-3.2× kumalugi afaka isisekelo sepompo.

Lapho Ukukhishwa Kwesanti Kudlula Ukutshala Kwezimali—Futhi Uma Kungenzeki

Abanye onjiniyela bayazenzakalela ekusetshenzisweni kokutshalwa kwezimali ukuze "ukunemba." Kodwa lokho kuwugibe. Ukufakwa kwezimali kotshalomali kuhle kakhulu ngaphansi kuka-15 kg nangaphansi kuka-150 mm ubukhulu bobukhulu—kodwa kuzabalaza namaphaseji angaphakathi amakhulu kuno-Ø25 mm noma ukuguquguquka kodonga okujiyile kuno-45 mm ngaphandle kwezinyembezi ezishisayo. Sisanda kuqalisa kabusha i-cobalt alloy nozzle oda: into efanayo ye-AMS 5387, ukuphrinta okufanayo, izinqubo ezimbili. Ukutshala izimali kulethe isivuno esingu-92%—kodwa kudinga amahora angu-11 okuhlanza i-EDM ingxenye ngayinye ukuze kukhishwe izinsalela zobumba kubhore yangaphakathi engu-320 mm. Ukulingisa isihlabathi? 98% isivuno, zero post-cast bore ukuqedwa okudingekayo, 37% isamba sezindleko eziphansi.

Nokho—ukusakazwa kwesihlabathi kwehluleka ngokushesha uma udinga izindawo eziwu-Ra ≤1.6 µm as-cast, noma izici ezincane kuno-Ø3 mm ezinokujula-kuya-kububanzi >4. Labo baya ngqo kumishini ye-CNC kusuka kubha eqinile. Asiphoqi izinqubo zokuhlanganisa. Ishidi lethu lokucaphuna lihlaba umkhosi lokhu kungqubuzana kusengaphambili, ngezinye izindlela ezibalwa ngesamba sezindleko ngeyunithi ngayinye yokusebenza—hhayi ngekhilogremu noma ngehora.

Ukuthi Kubukeka Kanjani Ukulawulwa Kwekhwalithi Yomhlaba Wangempela

“I-ISO-certified foundry” isho okuncane uma ukuhlola kuma kuma-tensile bar. Esikhungweni sethu se-Qingdao, yonke indawo yokukhiqiza isihlabathi iba nezindawo zokuhlola ezine eziyisibopho:

1. Ukuhlaziywa kweqoqo lesihlabathi elingenayo: Ukusatshalaliswa kwesisefo, okuqukethwe kobumba, nokulahlekelwa ekushiseni okufakwe nge-ASTM C1107 ngayinye.
2. Ukuqinisekisa ubulukhuni besikhunta ngaphambi kokuthulula: Ukufundwa kwe-Shore Scleroscope ≥72 kuzo zonke izindawo ze-cope/core, ezirekhodwa endaweni ngayinye yokusakaza.
3. I-post-shakeout scanning ultrasonic: Ukuhlolwa kwe-volumetric okungu-100% kokuncipha kwezingxenye ezibucayi—akukho sampuli.
4. Ukuqinisekiswa kokugcina kwe-CMM: Umbiko ogcwele we-GD&T ngokumelene nomdwebo wangempela, okuhlanganisa nokuhlolwa kokuzinza kwesici se-datum ngemva kokwelashwa kokushisa okudambisa ingcindezi.

Sigcina ukulandeleka okugcwele: izinombolo zesihlabathi esingavuthiwe, izingodo zesithando somlilo, amamephu wokuqina kwesikhunta, namafu wephoyinti le-CMM—konke kuhlanganiswe nenombolo yakho ye-PO. Akukho okuhlukile. Yileyo ndlela esiqinisekisa ngayo imizimba yamavalvu okucindezelayo ihlangabezana nezimfuneko ze-API 6D kuzo zonke izinkontileka zensiza ezintathu zaseNyakatho Melika—ngaphandle kokwehluleka kwenkambu eyodwa ezinyangeni ezingama-22.
