Lapho onjiniyela becacisa izingxenye ze-aluminium zama-hydraulic manifolds, izindlu zokumpompa, noma ama-winch system ezimoto, kuyaqabukela baqale “ngokuphonsa isihlabathi.” Baqala ngenkinga: ukuhamba ngebhayisikili okushisayo, ukubekezelela okuqinile kwe-GD&T, ubuqotho bengcindezi kubha engu-350+—kanye nemajini enguziro ye-micro-porosity noma i-dimensional drift. Kulapho a isihlabathi cast aluminium ifektri iyeka ukuba umthengisi futhi iba isandiso sokuklama. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sibone ukwehluleka okuthathu okuphindelelayo kumaphrojekthi wokuphonsa isihlabathi se-aluminium-hhayi kusukela ekusetshenzisweni okungekuhle kwe-Foundry, kodwa kusukela ekulindelweni okungalungile ekunikezeni ubunjiniyela.
Okokuqala: ukuthatha "i-aluminium" kusho i-A380. Ayikwenzi. Esitolo sethu, u-75% wokusakazwa kwesihlabathi se-aluminium kusebenza ku-A383 noma okuhlukile okungu-319 okulungiswe ngokwezifiso—ikakhulukazi uketshezi oluthuthukisiwe ezisekelweni zephampu ezinodonga oluncane kanye nokusebenza kahle ngemva kokwelashwa kokushisa kwe-T6. Okwesibili: ukusabalalisa okusanhlamvu kwesihlabathi sesikhunta. Sisebenzisa i-silica ehlanganiswe ne-resin ene-controlled 45–75 µm gradation—hhayi ngoba ijwayelekile, kodwa ngoba isika ukuhwaqazeka kwendawo (Ra) ngo-30% uma iqhathaniswa nesihlabathi esivamile esiluhlaza, sehlisa isikhathi sokugaya sangemuva kokusakazwa kumaflange ezindlu zamasilinda. Okwesithathu: ukweqa ukulingisa kwangaphambili kwe-FEA kokuncipha kokuqina. Elinye ikhasimende laseNyakatho Melika lisithumelele umdwebo wezindlu wephampu yepiston onombambo owugqinsi ongu-22 mm eduze kodonga oluyi-6 mm. Ukulingisa kumake indawo eyingozi enkulu. Siphakamise ukufakwa kwendawo okubandayo—futhi sasusa u-100% wemigodi eshwabene yangaphakathi ehluleke inqwaba yabo yokuqala ye-X-ray.
Yini ehlukanisa umuntu onekhono isihlabathi cast aluminium ifektri kusuka kuleso esiletha izingxenye ezibalulekile zemishini? Ukuhlanganiswa okuqondile—hhayi nje ukusakaza, kodwa iketango eligcwele ukusuka ekukhethweni kwengxubevange ukuya ekuqinisekiseni ukusebenza. Sithola kuphela ama-ingots e-aluminium aqinisekisiwe anemibiko egcwele yokuhlolwa komshini (ASTM B179, EN 1706), bese senza ukuhlaziya kwe-OES kuyo yonke inqwaba encibilikayo. Akukho okuhlukile. Amaseli ethu omshini we-CNC ahlala amamitha ukusuka esiteshini se-shakeout-ngakho-ke ukusakazwa kuthuthela ngqo ekulungiseni ngaphandle kokuphumuza ingcindezi okubangelwa izinga lokushisa. Sibamba kanjalo ±0.05 mm ezindaweni zama-valve body, ngisho nasezindlini ezinde ezingu-420 mm. "Asizami" ukushaya ukubekezelelana. Silawula indlela yokushisa ukusuka ekuthululeni kuya ekunqunyweni kokuqeda.
- Ukuhambisana kwe-cobalt-alloy: Yebo—sivamise ukuphonsa i-aluminium ngokufaka i-cobalt-nickel (AMS 5387, T800) yenhlanganisela yephampu eyingxube. Ukhiye ukuthulula okulandelanayo kanye nokulawula izinga lokushisa phakathi kobuso phakathi kuka-±15°C wephoyinti le-eutectic.
- Ukwenziwa kwe-GD&T: Siqinisekisa isikhundla, iphrofayili, kanye nokuphumayo sisebenzisa ama-CMM e-Zeiss CONTURA—hhayi ekuhlolweni kokugcina kuphela, kodwa ngemva komshini onzima futhi futhi ngemva kokuqeda ingcindezi.
- Ukulandeleka: Konke ukulingisa kuphethe ikhodi ye-QR emiswe nge-laser exhuma kulogi yayo encibilikayo, umbiko we-x-ray, ukuqina kokufundwa, nesitifiketi sobukhulu—akukho mzila wephepha, awekho amarekhodi alahlekile.
Abanye baphikisa ngokuthi ukukhishwa kwesihlabathi akukwazi ukufanisa ukufakwa kwe-investimenti kwe-aluminium geometries eyinkimbinkimbi. Kodwa ubunkimbinkimbi abukho mayelana nokubalwa kwengxenye-kumayelana nokuminyana kokusebenza. I-winch center shaft roller idinga ukusatshalaliswa kwesisindo esilinganiselwe, ukuqedwa kwendawo enezinga eliphezulu ku-OD, kanye nokuqondanisa kokhiye okunembe kuwo wonke ubude obungamamitha angu-1.2. Izibambo zokwenziwa kwesihlabathi ezingcono kunotshalomali lapho ukujiya kodonga kushintsha kusuka ku-8 mm kuya ku-45 mm. Kungani? Ngoba silawula izinga lokupholisa ngamakhaza asendaweni nemikhono evikelayo—hhayi nje okokusebenza kwesikhunta. Silethe ukukhishwa kwe-aluminium engu-210 kg nge-Cpk >1.67 kuma-bores abucayi, aqinisekiswa ngaphansi komthwalo kumabha angu-400 wokuhlola ama-hydraulic rigs.
Ukulethwa komhlaba wangempela kuncike ezintweni ezimbili iningi labathengi abangazinaki: ukulungela izinto ezibonakalayo kanye nokucubungula izinto obala. Sigcina ama-alloys angu-A383 nama-319 kumaqoqo angu-500 kg—ahlaziywe ngaphambili, omisiwe, alungele ukuncibilika phakathi namahora angu-24 okuqinisekiswa kwe-oda. Futhi sabelana ngezibuyekezo zokukhiqiza zesikhathi sangempela: hhayi nje "ukusakaza kuqalile," kodwa "ukuhlanganiswa kwesikhunta kuqedwe ngo-09:22, ukuthululwa okuhlelelwe u-14:00, i-shakeout elindelwe ngo-18:40." Lokho kubonakala kuvumela amaqembu okuthenga aqondise izinto, amaqembu e-QA ahlele izikhala ze-CMM, futhi onjiniyela bemiklamo baqinisekise ubukhulu be-athikili yokuqala ngaphambi kokuthi kuqale ukusebenza kwesibili.
Uma iphrojekthi yakho elandelayo yokusakazwa kwe-aluminium idinga okungaphezu kweshidi lokucaphuna—uma idinga ukuqonda kwe-metallurgical, ukuhlela isixhumi esibonakalayo se-casting-machining, kanye nokuthobela okubhaliwe kuwoyela negesi noma ama-hydraulics eselula—udinga uzakwethu ophatha ukukhishwa kwesihlabathi njengesistimu yobunjiniyela, hhayi isinyathelo sempahla. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngaleyo ndlela-hhayi ngoba izwakala kahle kuwebhusayithi, kodwa ngenxa yokuthi ama-valve okucindezela ayavuza, ama-pump housings aqhekekile, nama-winch shafts ayahluleka lapho ukuqagela kungena esikhundleni sedatha. Sakha izingxenye ze-aluminium ezisinda emijikelezweni yokuqala engu-10,000—kanye nezi-100,000 ezilandelayo.
