Lapho onjiniyela becacisa a ukuphonsa izingxenye ifektri kumavalvu we-hydraulic abalulekile kumishini noma ama-winch shafts agqoke kakhulu, awagcini nje ngokuthenga insimbi-bathenga ukuqina kobukhulu ngaphansi kwengcindezi yamabha angama-350, ubuqotho besakhiwo se-microstructure ngemva kokwelashwa kokushisa, kanye nokulandeleka okugcwele kwenqwaba kuze kufike kunombolo encibilikayo. Kungakho amaqembu aklamayo eNyakatho Melika naseYurophu aya ngokuya ehambisa izingxenye zephampu ye-cobalt-alloy eya e-Qingdao—hhayi ngezindleko eziphansi, kodwa ngokuziphatha okubikezelwe kwe-metallurgical kanye nokulethwa okungamangazi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza lapho ukubekezelelwa kokusakaza kuhlangabezana nokusebenza okusebenzayo: ±0.05 mm ezindlini zesilinda sephampu ye-piston, ukuthobela kwe-AMS 5387 kuqinisekisiwe ngokuhlaziywa kosayizi wokusanhlamvu we-ASTM E112, nokuqedwa kwendawo okugcinwe ku-Ra 0.8 µm ebusweni bokuvala umlomo we-cobalt-nozzle. Sibonile amakhasimende eshintsha abahlinzeki ngemva kokuhluleka kwamaqoqo amathathu e-T800 alloy plugs—isikhathi ngasinye, imbangela eyinhloko ilandelwa ekuhlakazweni kwe-carbide okungahambisani ngesikhathi sokuqina. I-Qiangsenyuan igwema lokhu ngokulawula kokubili ukuvunyeleka kwesikhunta sesihlabathi *kanye* nesixazululo sangemuva kokusakazwa kwamazinga werempu annealing endlini. Ayikho i-handoff. Akukho ukucabanga.
Ukuhlanganiswa kwabo okuqondile akulona ulimi lokumaketha-kuyisidingo senqubo. Thatha irola ye-winch yesikhungo semoto yobunjiniyela: insimbi eyi-ductile iron (ASTM A), emshinini omahhadla ku-5-axis DMG Mori, efakwe ukushisa kufika ku-28–32 HRC, bese iqeda ngempendulo ye-CMM esenqubo. Isinyathelo ngasinye sihlala ngaphansi kophahla olulodwa. Lokho kususa i-dimensional drift evamile lapho izitolo zithumela izikhala zemikhumbi ezitolo zemishini zangaphandle—ikakhulukazi lapho ukukhiqiza amajenali kudinga ukuphuma ngaphansi kuka-0.015 mm. Amaklayenti abika ukunqatshelwa kwe-athikili yokuqala okungu-40% okumbalwa uma kuqhathaniswa namamodeli wangaphambilini wezigaba eziningi.
Isiyalo esibalulekile asixoxiswana lapha. Ama-ingots e-cobalt-nickel eluhlaza afika nemibiko yokuhlolwa komshini obonisa ikhabhoni ≤0.12%, i-chromium 27–31%, ne-cobalt ≥60%—iqinisekisiwe ngaphambi kokuncibilika. Lapho i-OEM yephampu yaseYurophu ifuna ukulawula okuqinile kokuqukethwe kwe-delta ferrite ekubunjweni kwensimbi engagqwali, i-Qiangsenyuan ayizange imane ilungise amakhemikhali; bafake i-spectrometer ye-PMI ephathwayo esiteshini sokuthela futhi bafaka ukwakheka kwayo yonke into ngokumelene namajika okupholisa. Lelo zinga lokulawula imbudumbudu lichaza ukuthi kungani izingxenye zabo ze-AMS 5387 zidlula ngokuqhubekayo ukuhlolwa kwe-ultrasonic kwe-NDT Level III—akukho kuphinda kusebenze, akukho mvuthuluka.
Ukulethwa komhlaba wangempela kuncike ekuqondaneni konjiniyela—hhayi nje umthamo wokukhiqiza. Phakathi nokubuyekezwa kwe-GD&T komdwebo wezindlu zamavalvu okucindezelayo, ithimba labo lihlabe umkhosi ukubekezelela iphrofayela ye-0.02 mm ebusweni obungasebenzi be-flange. "Singakwazi ukuyibamba," basho, "kodwa yengeza isikhathi sokusebenza esingu-17% kanye nenzuzo yokusebenza engekho." Bahlongoze ukuyiphumuza ibe ngu-0.1 mm, yaqinisekisa ushintsho ngamamephu okusabalalisa ingcindezi e-FEA, futhi kwabelwane ngezifaniso zokunweba ezishisayo ezingabonisi umthelela kubuqotho bezimpawu. Lolo hlobo lokuxazulula izinkinga ngokubambisana—olusekelwe ku-physics, hhayi izithembiso zokuthengisa—yilo olushintsha ama-oda aphuma kanye abe ubudlelwano beminyaka eminingi. Kumaqembu adinga ukunemba kwezixazululo zokulingisa insimbi eziziphatha njengoba kubikezelwe, hhayi njengoba kulindelwe, indlela iqala ngokubuyekezwa kobuchwepheshe—hhayi isicelo sekhwowuthi.
