Lapho onjiniyela bayacacisa ukukhishwa kwesihlabathi sokucindezela okuphansi ngezingxenye zensimbi ezinembayo, azigcini nje ngokukhetha inqubo-zikhetha ihange elithembekile. Sizibonele mathupha: indlu yepompo ye-hydraulic iqhekeke ekuhlolweni kwenkundla ngoba i-Foundry yeqe ukumodela kokuqinisa. Elinye iklayenti libambezele ukwethulwa ngamaviki angu-11 ngemva kokuthola izindlu zesilinda ezinokusatshalaliswa kwamanodule e-graphite okungahambisani—akubonakali ngaphandle kwe-metallography, kodwa ebulalayo ngaphansi kokulayisha umjikelezo wamabha angu-350. Kungakho "imboni yokukhipha isihlabathi enengcindezi ephansi" ingelona igama lokusesha elijwayelekile. Kuyisihlungi—esihlukanisa abahlinzeki abaqonda ukulawulwa kwe-metallurgical kulabo abathela insimbi kuphela.
Kungani Ukusakazwa Kwesihlabathi Sokucindezela Okuphansi Kuletha Ukunemba Lapho Amandla Adonsela phansi Ehluleka
Ukusakaza kwamandla adonsela phansi kusebenzela izimo ezilula. Kodwa uma ingxenye yakho inezingxenye ezinodonga oluncane oluseduze nosinki bokushisa okukhulu—njengendlu yesilinda yephampu ye-piston enogqinsi oluyi-4.2 mm ongqimba olungena ku-68 mm flange—amandla adonsela phansi abangela isiyaluyalu, ukuvala okubandayo, kanye nokuncipha kwe-porosity lapho kuhlangana khona ingcindezi ebalulekile. Ukukhipha isihlabathi esinengcindezi ephansi kuxazulula lokhu ngokusebenzisa ibha engu-0.05–0.15 yokucindezela kwegesi engasebenzi kahle echibini lensimbi elincibilikisiwe. Lokhu kuphoqa insimbi ukuthi ikhuphukele phezulu ngeshubhu lesikhuphukeli se-ceramic ngesivinini esilawulwayo (imvamisa engu-12–18 mm/s), igcwalisa isikhunta ngomshini. Umphumela? Ukuqina okuqondile ukusuka phansi kuye phezulu, igesi evaleleke eduze kweziro, nokuzinza kwe-dimensional ngaphakathi kuka-±0.25 mm kuzici ezingafika ku-1,200 mm ubude.
Siqinisekisa lokhu nsuku zonke. Ku-AMS 5387 cobalt alloy nozzles, ukusakazwa kwengcindezi ephansi kufinyelela umsindo ongu-99.7% ekuhlolweni kwe-ultrasonic—kuqhathaniswa no-89% namandla adonsela phansi. Okubaluleke nakakhulu, iletha ukuhlakazeka kwe-eutectic carbide okungaguquki. Lokho kubalulekile ngoba amanethiwekhi e-carbide angalingani adala ukugqoka ngaphambi kwesikhathi ezindleleni zamanzi zesivinini esikhulu. Amakhasimende ethu kuwoyela negesi abika impilo yesevisi ende engu-3.2× kumapulagi asekelwe ku-T800 enza ngale ndlela uma kuqhathaniswa nezinye izindlela zokutshala imali—akukho ukunamathela okudingekile.
Amakhono Amane Angaxoxiswana Embonini Yokusakaza Isihlabathi Esinengcindezi Ephansi Yangempela
Indawo eqinisekisiwe ye-ISO 9001 iyisiteki setafula. Okuhlukanisa ozakwethu abalungele ukusebenza yindlela abahlanganisa ngayo ukusakaza nokufunwa phansi komfula:
- Ukulandeleka kokubalulekile kwehle kunombolo yokushisa: Yonke inqwaba ye-cobalt-nickel alloy ithwala ama-MTR agcwele ane-tensile, hardness, kanye nedatha yokuhlola ukugqwala kwe-intergranular—hhayi nje ikhemistri.
- Ukuqapha kokuqiniswa okungaphakathi kwenqubo: Amakhamera wezithombe ezishisayo alandelela ukuqhubeka kwangaphambili ngesikhathi sangempela; ukuchezuka kubangela ukulungiswa kwengcindezi okuzenzakalelayo noma kuhoxise.
- Ukuqinisekiswa kwephethini ehlanganisiwe ye-CMM: Ngaphambi kokuthela kuqala, siskena amaphethini ayinhloko ngokumelene ne-CAD sisebenzisa i-Zeiss CONTURA G2, sibambe amaphutha asalungiswa angadala umonakalo wokukhipha.
- Ikhono lokuqeda i-Hybrid: Ukusakaza kuphuma esiteshini se-shakeout futhi kuya ngqo kumashini we-CNC we-5-eksisi—akukho ukuphatha kwangaphandle. Lokhu kulondoloza ubuqotho be-datum kuzici ezibalulekile ze-GD&T ezifana nokuhlangana phakathi kobuso obubhorekile nobunyukayo (±0.015 mm).
Abanye bangase baphikise ukuthi ukukhishwa kwesihlabathi akukwazi ukufana nokuqedwa kwangaphandle kokutshala imali. Iqiniso - ngokuqedwa kwesibuko. Kodwa ngezindawo zokusebenza? I-as-cast Ra yethu ihlala ku-12.5 µm ebusweni obuthwala umthwalo, yehlela ku-1.6 µm post-machining. Lokho kulungile: ukushelela kakhulu kumema indlala yokugcoba ezinhlelweni ezishelela kakhulu njengamarola e-winch center shaft.
Lapho Ukunemba Kuhlangana Neqiniso Lohlelo
Ukukhishwa kwesihlabathi sokucindezela okuphansi kukhanya lapho i-physics nomsebenzi kungqubuzana khona. Cabangela amasistimu ewintshi emoto yobunjiniyela: amarola eshaft aphakathi nendawo abekezelela ukugunda okuhlangene kwe-torsional, umthelela we-radial, kanye nokungcoliswa kwe-abrasive. Irola ye-gravity-cast yehlulekile emijikelezweni engu-14,000. Inguqulo yethu yengcindezi ephansi—esebenzisa isihlabathi esiluhlaza esilungisiwe esinezithasiselo ze-bentonite nekhabhoni—yasinda emijikelezweni engu-62,000 ekuhlolweni okusheshisiwe. Kungani? Izinga lokupholisa elilawulwayo lilondoloze ama-carbide angu-22% ngaphezulu endaweni engaphansi komhlaba, kuqinisekiswe imephu ye-SEM/EDS.
Noma thatha ama-valve okucindezela amasistimu we-hydraulic. Amakhasimende afuna ukusebenza okungavuzi kubha engu-420. Inqubo yethu ibamba isithunzi sesihlalo sesango sibe ngu-0.008 mm ububanzi obungu-85 mm—okutholakala kuphela ngenxa yokuthi ukucindezela okuphansi kuqeda ukuguguleka kwesikhunta ekugcwaleni okuneziyaluyalu. Sikala zonke izihlalo zamavalvu nge-Taylor Hobson PGI Optics, hhayi nje amasampula amaningi.
Ukukhetha izinto ezibonakalayo kuhlanganisa inzuzo. Lapho uphonsa ama-alloys asekelwe ku-T800 cobalt, isikhunta esivamile sesihlabathi siqhekeka ngaphansi kokushaqeka okushisayo. Sisebenzisa ama-zircon-bonded refractory linings ashiselwe kuqala ku-220°C—agunyazwe ngama-thermocouple arrays ashumekwe ezindongeni zesikhunta. Lokho kuvimbela ama-microfissures okuba izindawo zokuqala zokuqhekeka kokukhathala.
Ukukhetha Imboni Yakho Yokusakaza Isihlabathi Sokucindezela Okuphansi: Bheka Ngalé Kwencwajana
Buza le mibuzo emithathu ngaphambi kokusayina i-PO:
- Ungakwazi yini ukusibonisa imibiko yokulingisa yokuqinisa yejiyomethri yethu ethile—okuhlanganisa indawo ebikezelwe yokushwabana nokusebenza kahle kokuphakelayo?
- Ingakanani ukuchezuka kwakho okuphezulu okuvumelekile phakathi kobukhulu be-as-cast kanye nobukhulu bomshini bokugcina kuzici ezidingayo kokubili ukusakaza ubuqotho kanye ne-GD&T eqinile?
- Ukuqinisekisa kanjani ukufana kwe-microstructure kukho konke ukulingisa okukodwa—ikakhulukazi ekushintsheni phakathi kwezingxenye eziwugqinsi nezincane?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iphendula zontathu ngezivumelwano ezibhaliwe—hhayi izithembiso. Isikhungo sabo se-Qingdao sisebenza ngokusakazwa kwesihlabathi esinengcindezi ephansi eduze kwemishini ye-CNC nokwelashwa kokushisa ngaphansi kophahla olulodwa. Awekho ama-handoffs. Akukho ukukhukhuleka kwe-dimensional. Akukho ukulandeleka okulahlekile. Basebenzela ama-OEM aseNyakatho Melika adinga izindikimba zamavalvu ezithobela i-ASME B16.34, abakhiqizi bephampu base-Europe abadinga ukufakwa kwensimbi kwe-EN 10213-G25, kanye nabakhi bemishini yezimayini yaseNingizimu-mpumalanga ye-Asia abafuna ukulingwa kwensimbi ukumelana nokuhuzuka—konke ngendlela efanayo yensimbi.
Uma ingxenye yakho elandelayo yensimbi enembayo kufanele ikwazi ukumelana nokucindezela okuphezulu, ukuguga okuphezulu, noma ukwehluleka kwemiphumela ephezulu, qala ngokuthi a umfutho ophansi wemboni yokuphonsa isihlabathi lokho akuphathisi ukulingisa njengesinyathelo—kodwa njengesisekelo sobuqotho bokusebenza.
