Amacandelo aphezulu kakhulu awanyamezeli ukuthotyelwa-ngokukodwa kwiinkqubo ze-hydraulic, i-oyile kunye ne-gas valves, okanye i-winch yemoto yobunjineli. Xa uxinzelelo lufikelela kwi-350 bar, amazinga okunxiba akhawuleza, kwaye ukukhwela ibhayisekile okushushu kugxininisa ubume be-microstructures, iindlela zokuvelisa ezisemgangathweni ziyadodobala. Kulapho ke ipowder metallurgy industry factory imodeli iyawa mfutshane-kungekhona ngenxa yokuba ayinakho amandla, kodwa ngenxa yokuba ayifane idibanise ukuphosa, i-high-alloy machining, kunye nokuqinisekiswa okusebenzayo phantsi kophahla olunye. Siye sabona abathengi betshintsha ababoneleli kathathu bezama ukufumana i-AMS 5387 cobalt alloy pump housings kunye nolawulo lwe-± 0.015 mm GD & T. Ngalo lonke ixesha, ukukhukuliseka okuphakathi kwenzeka phakathi kokuncipha kunye nokupasa kokugqibela kwe-CNC. Oyena nobangela? Ubunini benkqubo eqhekekileyo.
Kutheni le nto i-Metallurgy yodwa ingakwazi ukuhambisa iMishini-ebaluleke kakhulu iMfezeko
I-metallurgy yomgubo igqwesa kubunzima obusondeleyo-netha kunye nokusebenza kakuhle kwezinto-kodwa iyasokola kunye nentembeko yesakhiwo secandelo elishinyeneyo, ulawulo lweenkozo eziya ngakulo, kunye nozinzo lwe-post-sintering dimensional kumalungu afana ne-piston pump cylinder housings. Kwimveliso yokwenyani, silinganise ukuya kuthi ga kwi-0.12 mm warpage emva konyango lobushushu kwi-PM-forged T800 imilomo yealloy. Oko kudlula i-speccle clearance esebenzayo nge-4×. Ukwenziwa kotyalo-mali kuzisa ingxinano engcono kunye namandla e-isotropic; ukugalwa kwesanti kubamba ubunzima kunye ne-thermal inertia ngokuqikelelwa ngakumbi. Kodwa ayisebenzi ngaphandle kokudibanisa ngokuqinileyo kumatshini ochanekileyo. Ivenkile yethu eQingdao iye yalahla iibhetshi zeprototype ezingama-27 kwisithuba seminyaka emihlanu-hayi kwiziphene zoyilo, kodwa kwiinkqubo ezingahambelaniyo. Ukulungiswa kwakungeyona ipowder engcono-yayikudityaniswa ngokuthe nkqo: ukuphosa, ukunciphisa uxinzelelo, i-multi-axis milling, kunye nokugqiba konke phantsi kophahla olulodwa lwe-ISO-certified.
Izakhono ezine ezivala umsantsa wokuSebenza
Sakhe indawo yethu malunga nezakhono ezine ezingaxoxisiyo-nganye ibonakalisiwe kumaziko osasazo kuwo wonke uMntla Melika, eJamani naseSingapore:
- Ubuchule beCobalt-nickel superalloy: Hayi nje ukwenza i-AMS 5387 okanye i-T800-siqinisekisa yonke ininzi yobushushu ngokuchasene ne-ASTM E112 ubungakanani beengqolowa, senze uvavanyo lwe-spark pre-machining, kunye nokulandelela ukuhanjiswa kwe-carbide nge-SEM-EDS imephu kumacandelo abalulekileyo afana neendonga zomqala womqala.
- Hybrid casting-machining workflows: Kumzimba wevalve yoxinzelelo lwehydraulic, siphosa esantini eluhlaza, emva koko senze i-5-axis contour milling epheleleyo *phambi* kokugqibela koxinzelelo loxinzelelo-ubambe indawo eyinyani ngaphakathi kwe-0.008 mm kwi-Ø12 mm pilot bores efumana imikhono yokutywina.
- Ukuhlola okusebenzayo-kuqala: Yonke isiseko sempompo sifumana uvavanyo lobungqina be-hydrostatic kwi-1.5 × uxinzelelo olusebenzayo, lulandelwa ngukuqinisekiswa kwe-CMM ye-32 GD & T callouts-kubandakanywa ukunyamezela kweprofayili edibeneyo kwiiflange zokukhwelana.
- Ukulandeleka kwebhetshi epheleleyo: Izatifikethi zezinto ezikrwada, iilogi zesithando somlilo, iirekhodi zesixhobo, kunye neengxelo zokuhlola zidityaniswe ne-ID yecandelo elinye. Ukuba i-winch center shaft roller ayiphumelelanga ebaleni, siyakha kwakhona imbali yayo yonke ngaphantsi kwemizuzu engama-90.
Oko Abathengi Bakubuzayo Ngokwenyani-kwaye bangayithethiyo ngokuvakalayo
"Ngaba ungabamba i-0.005 mm ukujikeleza kwiplagi ye-cobalt eyi-200 mm?" Ewe-kodwa kuphela ukuba siwumatshini ngokuseta ezimbini: ukurhabaxa kwi-gantry mill, ukugqiba kumatshini odikayo othe tyaba othe tyaba onezixhobo eziphilayo. "Ingaba uyanikezela ngempendulo yoyilo lokwenziwa kokwenziwa?" Ngalo lonke ixesha-kwaye sifaka iflegi imingcipheko kwangoko: umthengi wake wachaza udonga oluyi-0.3 mm kwi-AMS 5387 flow divider housing. Silinganise uxinzelelo lwe-thermal ngexesha lokuphosa kwaye sabonisa ukuba kunokwenzeka ukuqhekeka kudlule i-68%. Ihlaziywe kwi-0.8 mm. Kugqitywe ukuqinisekiswa komjikelo we-10,000.
Yintoni engathethwayo? Ixhala lexesha eliphambili. I-OEM yaseYurophu yayidinga i-42 ye-cobalt alloy nozzles kwiimpompo ze-offshore subsea-iiveki ezi-8 ukusuka kwi-PO ukuya ekuhanjisweni. Iivenkile eziqhelekileyo ze-PM zicaphula iiveki ezili-14. Sizise ngeentsuku ezingama-37 ngokulandelelana ukuphosa, ukuphatha ubushushu, kunye nomatshini kwimisinga enxuseneyo, sisebenzisa izixhobo ezizinikeleyo kwiqashiso ngalinye. Akukho bhetshi ilindileyo. Akukho zilophu zokuphinda zisebenze.
Iziphumo zeLizwe lokwenyani, hayi izithembiso
Abathengi bethu bathumela iinxalenye kwiindawo apho ukusilela kuthetha ukuba ixesha lokuphumla lixabisa i-240,000 yeedola ngeyure. Ke silinganisa impumelelo kwiziphumo-hayi imveliso:
- Umvelisi wesithuthi sobunjineli waseMzantsi-mpuma Asia unqumle ukusilela kwenkqubo ye-winch kwintsimi ngama-92% emva kokutshintshela kwi-PM bushings esuka kumazwe angaphandle ukuya kwii-roller zethu ze-steel-cast hybrid centre shaft rollers-eziqinisekisiweyo kwiinyanga ezili-18 kunye ne-3.2 yezigidi zeekhilomitha zokusebenza.
- I-OEM yaseMelika ye-hydraulic ye-hydraulic yehlise i-valve yokutshintsha isihlalo sokuphindaphinda ukusuka kwiiyure zonke ze-4,200 ukuya ngaphaya kweeyure ze-12,000 usebenzisa iiplagi zethu ze-T800 ze-alloy-zivavanywa phantsi kwe-pulsating 280 bar imithwalo kunye ne-0.5 Hz yokutshayela rhoqo.
- Abadibanisi bempompo yaseYurophu babika i-30% imijikelezo yokugunyazisa ngokukhawuleza xa sifumana izindlu zethu ze-cylinder-kuba yonke imingxuma yokunyuka, intambo ye-port, kunye ne-bearing bore idibana ne-ASME B16.5 kunye ne-ISO 2768-cK ngaxeshanye.
Olu ayilulo ulungiselelo lwethiyori. Yinto eyenzekayo xa uqeqesho lwe-metallurgical ludibana nokuchaneka komatshini-kwaye xa a ipowder metallurgy industry factory iyavela ngaphaya komgubo wedwa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ukusuka eQingdao, eTshayina. Indawo yayo ixhasa imfuno ye-B2B yehlabathi jikelele yamacandelo esinyithi entembeko ephezulu-ngaphandle kweenkqubo ezingundoqo zokukhupha okanye ukuhlalutya ukuphendula. Kwiinjineli ezichaza iindawo apho ijometri, i-microstructure, kunye nomsebenzi zidibana phantsi kweemeko ezinzima, umbuzo awukho "Ngaba unokwenziwa?" Ithi "Ngubani umnini wekhonkco lonke-ukusuka kukhetho lwe-alloy ukuya kuvavanyo olusebenzayo?" Obo bunini ngumahluko phakathi kwenxalenye kunye nesisombululo.
