Umxhuzulane osisigxina izisombululo zefektri zokubumba zifuna okungaphezulu nje kwesinyithi esityhidiweyo kunye nokubumba kwentsimbi. Bafuna ulawulo oluchanekileyo lwe-thermal, ulawulo lobomi obuphindaphindayo, kunye nokuqeqeshwa kwe-metallurgical-ingakumbi xa kuvelisa i-high-integrity components for hydraulic pumps, i-oilfield valves, okanye iinkqubo ze-winch yemoto yobunjineli. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphose ngaphezulu kwe-12,000 yentsimbi kunye neenxalenye zentsimbi kwi-mold esisigxina ukusuka ngo-2018-kwaye konke ukungaphumeleli, yonke i-dimensional drift, yonke isiganeko se-micro-shrinkage sifundise into enye: ukuphosa umxhuzulane ayikokugalela nje. Kulawulwa ukuqina.
Kutheni iSigxina soMxhuzulane wokuMngunda kusaphumelela kuMacandelo oShishino oluPhakathi
Ezinye iinjineli zicinga ukuba ukuphoswa kotyalo-mali kungena endaweni yomxhuzulane wokubunjwa okusisigxina. Kodwa kwimveliso yokwenyani-hayi i-lab specs-i-mold esisigxina ihambisa ukuphindaphinda okuthe kratya komgangatho wezindlu ezinjengeebhloko zepiston pump cylinder kunye nemizimba yevalve yoxinzelelo. Ngoba? Ngenxa yokuba iqondo lokushisa lokungunda lihlala ngaphakathi kwe ± 5 ° C kwi-300 + imijikelo xa usebenzisa i-preheated, i-H13 ifakwe izixhobo zentsimbi. Ukuchithwa kwesanti akukwazi ukuhambelana noko kuzinza. Ukwenziwa kotyalo-mali kwazisa ukuguquguquka kweqokobhe leceramic kunye noxinzelelo oluphezulu lwentsalela. Siyayilinganisa: kwi-420 mm × 280 mm × 120 mm isiseko sempompo yokuphosa, isikhunta esisisigxina sibambe ukunyamezela kwe-GD & T kwi-± 0.15 mm ngaphezu kweeyunithi ezingama-500; I-avareji yokuphosa isanti ± 0.32 mm, kunye ne-17% yenkunkuma ngenxa yokutshintsha okungundoqo.
Siqhuba imigca emibini ezinikeleyo yomxhuzulane esisigxina-enye yentsimbi ye-ductile (ASTM A), enye yensimbi ephantsi kwe-alloy (A105N). Zombini zisebenzisa i-gating yokugalela ezantsi, ufakelo olubandayo kumacandelo abalulekileyo, kunye nexesha lokwenyani lokujonga i-thermocouple kwiindonga zomgodi wokungunda. Akukho ngqikelelo. Akukho xesha "eliqhelekileyo" lomjikelo. Inxalenye nganye ineprofayile yayo yokuqinisa imephu kwiingxelo zethu zokuqinisekisa inkqubo.
Apho uninzi lweefektri zisilela khona—kunye nendlela esizilungisa ngayo
Uninzi lwemisebenzi yokwenziwa komzi-mveliso wokungunda womxhuzulane esisigxina iyawa kwiindawo ezintathu: ukuthotywa kokungunda, ukufudumeza kwangaphambili okungahambelaniyo, kunye noyilo olungonelanga lwesikhuphukeli sokutya okuthe ngqo kwealloyi. Sibone oku ngokuzibonela kwi-AMS 5387 cobalt ingxubevange yempompo ye-odolo yezindlu. I-castings yokuqala ye-19 ibonise i-subsurface porosity kufuphi ne-flange-nangona i-chemistry egqibeleleyo. Unobangela weengcambu? I-oxidation yomhlaba wokungunda emva kwemijikelo engama-42 itshintshe izinga lokutsalwa kobushushu. Isisombululo: ngoku sibumba i-recondition yonke i-35 shots sisebenzisa i-alumina blasting kunye ne-proprietary borosilicate coating-iqinisekiswe ngovavanyo lwe-infrared emissivity phambi kokugalelwa ngakunye.
Sikwanyanzelisa uqeqesho olungqongqo lwe-preheat. Ukungunda kwethu akungeni kwiziko elibandayo. Zicwilise kwi-280 ° C kwimizuzu engama-90, emva koko i-ramp ukuya kwi-320 ° C ± 3 ° C kwaye ibambe imizuzu engama-45-ilinganiswe kwiindawo ezintathu ezinzulu. Ayinangxoxo leyo. Yitsibe, kwaye ufumana iintanda ezibandayo okanye ukungahambi kakuhle kwizinto ezisekelwe kwi-T800. Abathengi ababonelela ngokubumba kwabo bahlala bengayihoyi le nto. Sivavanya ezabo phambi kokwamkelwa.
Ukudityaniswa Lelona ncedo lokwenyani—Akukokudlala nje kuphela
Isicombululo somzi mveliso sokugalela umxhuzulane osisigxina asiyeki ekushukumeni. Iyaqhubeka ngoomatshini, unyango lobushushu, kunye ne-metrology-zonke ziphantsi kophahla olunye. Kwiziko lethu le-Qingdao, i-cast cylinder yendlu ihamba ngokuthe ngqo ukusuka ekususeni ukungunda ukuya kwi-CNC ivula i-Mazak Integrex i-200S. Akukho kulibaziseka kwamalungiselelo. Akukho monakalo wokuphatha. Akukho lulungelelwaniso lusetwa ngokutsha. Sitshiza amabhobho abalulekileyo ngelixa ukuphosa kusekho ngaphakathi kwe-50 ° C ye-solidus yeqondo lokushisa-ukunciphisa ukuchithwa kwe-40% xa kuthelekiswa nomatshini wokushisa igumbi.
Ukuhlanganiswa kwethu ngokuthe nkqo kugubungela imigangatho emine: ukuqinisekiswa kwezinto (bonke ubushushu obulandelekayo kwiingxelo zovavanyo lokusila), ukuqinisekiswa kwenkqubo yokuphosa (kunye nesampulu ye-radiographic kunye ne-ultrasonic nge-ASME B16.34), i-machining echanekileyo (i-CMM-iqinisekisiwe kwi-ISO 2768-mK), kunye novavanyo olusebenzayo (uvavanyo loxinzelelo lwe-hydrostatic ukuya kwi-450 bar kwi-rigs ye-custom). Yiyo loo nto i-winch centre shaft rollers yethu yezithuthi eziphuma kuhola wendlela zifikelela kwi-100% yesivuno sokuqala-nangona ziteyiphu ezingekho mgangathweni kunye neendawo eziphazamisekileyo.
Ukukhetha iqabane lakho akukho malunga nexabiso-Kumalunga nokuqikelela
Ukuba iprojekthi yakho idinga umxhuzulane osisigxina wokubumba umzi-mveliso othunyelwa ngexesha, ubambe i-GD&T ngaphandle kwengxoxo, kunye neeflegi umngcipheko wokwenziwa kwezixhobo phambi kokuba kuqale isixhobo—udinga isakhono esibhaliweyo, hayi amabango okuthengisa. Buza le mibuzo mithathu phambi kokuba utyikitye:
- Ngaba ungandibonisa iipakethe zakho ezintathu zokugqibela zePPAP-kubandakanya iilogi zokugcinwa komngundo kunye neetshathi zobushushu bomgodi?
- Ngaba wenza uhlalutyo lwe-spectrographic kwinkqubo kubo bonke ubushushu, okanye kuphela kwiibhetshi zenqaku lokuqala?
- Xa ukuphosa kusilela kwi-NDT, ngaba uyayikhupha ingxelo yesenzo sokulungisa—okanye uphinde ulahlekise?
Senza sobathathu. Ngalo lonke ixesha. Inkqubo yethu ye-ISO 9001: 2015-eqinisekisiweyo ilandelela yonke imbumbulu yokudubula, yonke into ekrwada, yonke indawo ye-CMM yophando. Akukho ngaphandle. Yiloo ndlela esixhasa ngayo abathengi kulo lonke elaseMntla Melika, eJamani, naseSingapore-nokungabikho kade kokuhanjiswa kwii-odolo ezinomthamo ophakathi ngo-2023.
Xa sijonge phambili, sandisa amandla ethu omxhuzulane asisigxina okwenza imveliso yokungunda kwiinkqubo ezixubeneyo: kufutshane-netha-imilo yokubunjwa ngokusisigxina egqitywe nge-laser-assisted CNC milling ye-cobalt-nickel alloys. Akunjalo ngenxa yokuba inoveli-kodwa ngenxa yokuba idatha yasendle ibonisa ukuba inciphisa ixabiso lilonke nge-22% kwiindawo ezifuna zombini ijometri enzima kunye nokuxhathisa okugqithisileyo. Ukuchaneka akulosebe. Lulandelelwano.
