Xa iinjineli zicacisa iindawo ezintsonkothileyo, ezinentembeko ephezulu yesinyithi kwiinkqubo ze-hydraulic okanye i-oyile kunye nenkonzo yegesi, abafane baqale "ngokulahleka kwegwebu." Baqala ngengxaki: indlu yevalve evuza ngaphantsi kwe-400 bar, i-piston pump cylinder ene-micro-cracks emva kokuhamba ngebhayisekile eshushu, okanye i-winch center shaft roller engaphumeleli kwangaphambi kwexesha kwiimeko ze-abrasive offshore. Kulapho ukuphosa amagwebu okulahlekileyo akubiyiyo nje inketho-kodwa kuphela kwesisombululo esisebenzayo. Kwaye kulapho a umzi-mveliso wokuphosa amagwebu olahlekileyo ngoqeqesho olunzulu lwe-metallurgical kunye nolawulo lwenkqubo edibeneyo yenza umahluko.
Ukuphosa amagwebu okulahlekileyo ayisiyonto nje “yokugalela isanti enogwebu.” I-hybrid subtractive-additive hybrid echanekileyo: ipateni ye-EPS eyenziwe nge-CNC igqunywe, ingcwatywe kwisanti ye-silica engabotshwanga, emva koko i-vaporized * in situ * ngesinyithi esinyibilikisiweyo. Akukho migca yokwahlula. Akukho core wokutshintsha. Akukho ziengile zedrafti ezinciphisa ijometri. Kodwa impumelelo ixhomekeke kwizinto ezintathu ezingaxoxisiyo-ipateni uzinzo ngexesha lokutyabeka, ulawulo oluchanekileyo lwe-metallostatic yoxinzelelo ngexesha lokugalela, kunye nokujongwa kwexesha lokwenyani lobushushu ukunqanda ukushwabana kwe-porosity kumacandelo ashinyeneyo. Siye sabona abathengi betshintshela kwi-investment casting kwi-foam elahlekileyo ye-AMS 5387 cobalt alloy pump parts-kwaye banqumle ixesha lokuhamba nge-37% ngelixa bephucula isandi sangaphakathi. Ngoba? Kuba umthengisi wabo wangaphambili waphatha ugwebu njengento enokulahlwa. Olwethu luthatha njengecandelo lokuqala elichanekileyo kwikhonkco.
Uninzi umzi-mveliso wokuphosa amagwebu olahlekileyo abaqhubi bagxininisa umthamo okanye ukulula-izindlu ezinkulu zentsimbi ye-ductile, izibiyeli ezisisiseko, iintsimbi eziphantsi. Bambalwa ababamba i-T800 cobalt-based alloys okanye i-cobalt-walled, i-high-aspect-retiyo imilomo efuna i-±0.15 mm ukuphindaphinda komlinganiselo kwii-200 mm ubude. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sisebenza ngomatshini iipatheni zogwebu kumaziko e-CNC e-5-axis kungekhona ngenxa yokuba i-flash, kodwa ngenxa yokuba i-0.08 mm ukutenxa komphezulu kwipatheni iguqulela ngokuthe ngqo kwi-0.12 mm ye-offset kwindawo yokugqibela yomatshini emva kokuxutywa kunye nonyango lobushushu. Indawo yethu ehambelana ne-ISO iqhuba ukuhamba komsebenzi okuhambelanayo: umgca omnye onikezelwe kwi-cobalt-nickel alloys (AMS 5387, L-605), enye ilungiselelwe i-ferritic stainless steel castings esetyenziswa kwiziseko zempompo yegesi emuncu. Umgca ngamnye unendlu yawo yokwambathisa yokufuma elawulwayo, ipateni ye-oveni yokubhaka kwangaphambili, kunye nesikhululo sokugalela esincedisa ukufunxa esilungelelaniswe ukuya ku-±2.5 kPa.
Nantsi into eyahlula ukuphunyezwa okuthembekileyo kwisakhono sethiyori:
- Ukulandeleka kwezinto kuqala ngaphambi kokunyibilika: Yonke i-billet ye-T800 ifika kunye neekhemikhali eziqinisekisiweyo zobushushu, ubungakanani bengqolowa, kunye neengxelo ezixinzelelekileyo-kungekhona nje ii-certs ze-mill. Siphinda sivavanye imathiriyeli engenayo ye-Co, Cr, Ni, W, kunye ne-C sisebenzisa i-OES, emva koko sabele ii-ID zebhetshi ezidityaniswe neqashiso lokuphosa ngalinye.
- Akukho "ibhokisi emnyama" egqityiweyo: Emva kwe-shakeout, yonke intsimbi okanye i-steel casting idlula i-stress-relief annealing nge-ASTM A781, ilandelwa ukuhlolwa kwe-ultrasonic (ASTM E186) kumacandelo abalulekileyo. Amalungu e-Cobalt aya ngqo kwisisombululo se-anneal + ukucima ngokukhawuleza-akukho kupholisa komoya, akukho kuguquguquka.
- Umatshini awukho ezantsi-uyilwe ngokubambisana: Xa umthengi ethumela umzobo we-GD & T-enzima kumzimba wevalve yoxinzelelo, iinjineli zethu azicaphuli nje ukwenza machining. Bafanisa ukuqina kwi-MAGMAsoft, iindawo zokunyuka kweflegi eziphazamisa iindawo zokugqibela ze-datum, kwaye zicebise ukuguqulwa kweepatheni eziphelisa ukulungiswa kwesibini-ukugcina i-$ 18.40 ngenxalenye kwivolumu ephakathi.
Abanye bathi ugwebu olulahlekileyo alukwazi ukuhambelana nokugqitywa komphezulu wotyalo-mali. Yinyani-kwizicelo zeRa 0.8 µm, ayizukwenza njalo. Kodwa kwimigangatho esebenzayo eya kuba phantsi okanye igqitywe? I-foam elahlekileyo ihambisa ukufana okuphezulu kwe-microstructural kumacandelo anzima. Silinganise i-12% esezantsi yobunzima obuguquguqukayo kwi-65-mm-thick AMS 5387 cylinder yodonga lwezindlu xa kuthelekiswa nokuphoswa kotyalo-mali olulinganayo-ibotshelelwe ngokuthe ngqo ekuqinisweni okucothayo, okuthe kratya okuthe kratya kumngundo wesanti. Oko kuhambelana kubalulekile xa iwaranti yempompo yomthengi wakho ixhomekeke kubomi bokudinwa kwimijikelo eyi-10⁷.
Ukuba uvavanya a umzi-mveliso wokuphosa amagwebu olahlekileyo, buza imibuzo emithathu ngaphambi kokuphonononga izicatshulwa: Ngaba banokuqinisekisa ukuqina kwepateni emva kokugquma kunye nokomisa? Ngaba baloga ubushushu, inqanaba le-vacuum, kunye nentloko ye-metallostatic kubo bonke ubushushu? Kwaye-ngokubaluleke kakhulu-ngaba babamba idatha yokuhlolwa kokugqibela kwayo yonke into eyenziwayo, hayi iisampulu nje zeqashiso? E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ayizobhokisi zokukhangela ezo. Ziqheliselo lwemihla ngemihla. Sithumele ngaphezulu kwe-1,200 eyodwa ye-cobalt kunye nentsimbi engenasici kwii-OEMs zaseMntla Melika ukusukela ngo-2021-zonke zineengxelo ezipheleleyo zeCMM, izingodo zokuphatha ubushushu, kunye nokulandeleka kwezinto ezibuyela kwi-ingot. Akunjalo ngenxa yokuba kulula. Ngenxa yokuba iinxalenye ezibalulekileyo zobuthunywa azishiyi ndawo yeengqikelelo.
Ikamva lokuphosa ngokuchanekileyo alikho malunga nokukhetha phakathi kweenkqubo-imalunga nokuthelekisa ulandelelwano oluchanekileyo lomsebenzi wenxalenye. Ugwebu olulahlekileyo lwengqibelelo yokwakheka kwe-net-net. I-CNC yolawulo lwedatha esebenzayo. Unyango lobushushu lokunyaniseka kwe-microstructure. Ukugqibezela ukusebenza kojongano. Olo ludibaniso-oluyilwe, lwenziwe, lwaza lwaqinisekiswa njengenkqubo enye-yinto ejika inkcazo yokuphosa ibe yinto eqinisekisiweyo yentsimi. Kwiinjineli ezidiniweyo kukuleqa amaxabiso okulahlwa, ukulibaziseka kokuhanjiswa, okanye isinyithi esingaguqukiyo, inyathelo elilandelayo asiyonto enye iRFQ. Luphononongo lobugcisa kunye neqabane eliphatha igwebu njengesixhobo esichanekileyo, i-cobalt njengenguqu eyaziwayo, kunye nexesha lakho njengexesha lekhontrakthi.
