Xa iinjineli zichaza a metal ukubunjwa kwemveliso kwiindawo ezichanekileyo zoshishino, azithengi nje i-castings-zikhusela ukuzinza kwe-dimensional phantsi kwe-300-bar yoxinzelelo lwe-hydraulic, ukuhambelana kwe-microstructural kwiibhetshi zeeyunithi ze-500, kunye nokunyamezela kwe-porosity kwi-cobalt alloy nozzles. Leyo yinyani yokusebenza esiyibona imihla ngemihla kwi-Qingdao Qiangsenyuan Technology Co., Ltd-indawo apho ukuchithwa kwesanti kungakhutshelwanga kwi-subcontractor, kwaye ukuchithwa kotyalo-mali akuhlulwe kwi-CNC yokugqibela ngemimandla yamaxesha amathathu.
Kutheni le nto “iMzi-mveliso yokubunjwa kwesinyithi” ithetha Ngaphezulu nje kokungunda
Uninzi lwabathengi babhidanisa "ukubunjwa kwesinyithi" kunye nokuphosa ukufa. Ayiyo. Kwiziko lethu le-Qingdao, i-metal mold ibhekisela ekusetyenzisweni kwakhona, izixhobo zentsimbi ezisetyenzisiweyo ezisetyenziselwa ngokukodwa ukuveliswa komthamo ophantsi-ukuya-phakathi wentsimbi ephezulu yengqibelelo kunye neentsimbi zentsimbi-ingakumbi amacandelo afana nezindlu ze-piston pump cylinder kunye nemizimba yevalve yoxinzelelo efuna zombini ukunyaniseka komphezulu kunye nokuthotyelwa kwe-GD & T emva komatshini. Siye sabona abathengi bebuya bevela kwiiprototypes ezimbini ezingaphumelelanga kwenye indawo kuba umthengisi wabo uphathe i-AMS 5387 cobalt alloy ngokungathi yi-A380 aluminiyam: uyilo olufanayo lokungena, ixesha lokushukuma elifanayo, umjikelo ofanayo wokuphatha ubushushu. Yaqhekeka kuma-42% amandla esivuno. Sihlengahlengisa i-mold preheat ukuya ku-±5 °C, silawula izinga lokuqina ngokubeka indawo ebandayo, kwaye siqinisekise isithuba se-interdendritic nge-SEM ngaphambi kokugalela kuqala.
Izakhono ezine eziphelisa i-Handoffs-kunye nokusilela
Sidibanisa iinkqubo ezine zobuchwephesha ezahlukeneyo phantsi kophahla olunye-hayi njengamanyathelo alandelelanayo, kodwa njengolawulo oluxhomekeke omnye komnye:
- Ubunjineli benkqubo yokuphosa: Hayi ukwenza ipateni kuphela. Simisela i-gradients ezishisayo kwi-MAGMASOFT kwijiyometri entsha nganye, siqinisekisa izibonelelo zokuncitshiswa ngokuchasene nedatha ye-CMM yokwenene evela kumaqashiso angaphambili, kwaye sigcine zonke iifayile zokulinganisa ukuphicothwa kwabathengi.
- Multi-axis CNC machining: Oomatshini bethu be-Mazak INTEGREX i-200S banqumle i-cobalt eqinile ye-T800 i-cobalt alloy kwi-12 m / min feed-ngaphandle kwe-carbide chipping-kuba thina pre-umatshini iimpawu zokunciphisa uxinzelelo * kwi-* idizayini yokuphosa ngokwayo.
- Ungqamaniso lonyango lobushushu: Akukho migca yangaphandle yeziko. Siqhuba i-ASTM A995 yeBanga le-6A i-stainless casting ngokusebenzisa isisombululo, ukucima, kunye nokwaluphala endlwini-enokulandeleka kwilog yesithando somlilo, indawo ye-thermocouple, kunye nobude bexesha lokufunxa.
- Ukuhlolwa okusebenzayo: Yonke i-winch center shaft roller ijikelezisa kwi-rig yethu yovavanyo oluguquguqukayo olwakhiwe ngokwesiqhelo kwi-1,800 RPM ngelixa ilayishwe kwi-120% ye-torque ekalisiweyo. Ukugqitywa komphezulu? Ukulinganiswa nge-interferometry yokukhanya okumhlophe-kungekhona i-stylus profilometry-kuba uRa yedwa ulahlekelwa i-micro-valley geometry ebalulekileyo yokugcina igrisi.
Iindleko zokwenyani zoBonelelo lweMpahla "oLungileyo".
Abanye abathengisi bacaphula i-cobalt-nickel castings usebenzisa i-ingot engaqinisekanga-ukunciphisa iindleko nge-18%, emva koko batyhola "ukuguquguquka kwezinto" xa iimvavanyo ze-tensile zingaphumeleli. Sifumana kuphela i-AMS 5708-certified T800 alloy, eneengxelo ezipheleleyo zovavanyo lwelitye lokusila kunye nokulandelelwa kwenombolo yobushushu emva kokunyibilika kwevacuum induction. Kwikota yokugqibela, i-OEM yepompo yaseYurophu inqatshelwe iiyunithi ze-142 ukusuka komnye umthengisi ngenxa yokuba umxholo we-sulfure uqhubekile ukuya kwi-0.012%-ngaphezu komda we-0.008% wokumelana nokukhathala. Ukuhlolwa kwethu okungenayo kubambe ibhetshi efanayo kwi-0.0079%-iqinisekiswe yi-OES spectroscopy ngaphambi kokukhulula. Ayilothamsanqa elo. Yinkqubo ebhaliweyo, izixhobo ezilungelelanisiweyo, kunye neengcali zemetallurgists ezichaze iialloys ze-cobalt kwizikhondo zevalve ye-subsea ukusukela ngo-2011.
Oko Kufunwa Ngoononjineli—Asikuko Oko Iincwadana Ezinemifanekiso Zithembisayo
Awudingi "isiqinisekiso se-ISO 9001." Ufuna i metal ukubunjwa kwemveliso ebonisa ukungqubana kwe-GD&T *phambi kokuba* kuqale isixhobo—njengaxa ukunyamezelana komthengi ±0.01 mm kwi-32-mm-diameter kungquzulwano olulindelekileyo lokungunda kwisanti eluhlaza. Siphendula kwiiyure ezingama-48 ngemizobo ecacileyo ebonisa ezinye izakhiwo zedatha, ezinye iindlela zokulahla, okanye izibonelelo zokwenza indawo-zonke zixabisa umgca-ngomgca. Asithi "ewe" kwiinkcazo ezingenakwenzeka. Sithi "nantsi indlela yokufezekisa umsebenzi, ngokuthembekileyo."
I-Qingdao Qiangsenyuan Technology ihambisa i-castings echanekileyo apho ukusebenza kungenakuthintelwa: kwiimpompo zodaka ze-oilfield eziqhuba i-24 / 7 kwi-120 ° C, kwiinkqubo ze-hydraulic ezilawula i-80-toni ye-excavator booms, kwiimpompo ezikhethekileyo ezihamba i-slurry e-corrosive kwi-pH 1.5. Ukuba inxalenye yakho idinga i-AMS 5387 cobalt alloy, i-tight-as-machined surfaces kwintsimbi etyhidiweyo, okanye ukuqinisekiswa okusebenzayo ngaphaya koluhlu lokukhangela i-dimensional-udinga iqabane eliphatha ukuphosa njengempahla, kodwa njengoluhlu lokuqala lobunjineli bokuthembeka kwenkqubo. Lo ngumgangatho esiyakhela kuwo-konke ukugalela, yonke into, yonke into ehlolwayo.
