Xa iinjineli zicacisa ukuchaneka kwentsimbi yokuphosa iinxalenye zefektri yezixhobo eziphezulu zokunyamezela, azigcini nje uku-odola isinyithi-zikhusela ingqibelelo yokusebenza phantsi kwe-350 bar yoxinzelelo lwe-hydraulic, ukuxhathisa i-slurry abrasive kwi-120 ° C, okanye ukugcina i-± 0.015 mm ukujikeleza kwi-shaft ejikelezayo yepompo emva kweeyure zokusebenza kwe-1000. Elo nqanaba lokuthembeka aliveli kwiziseko eziqhelekileyo. Ivela kumaqabane aphatha i-metallurgy njengobunjineli-hayi ukuvelisa.
Kutheni uzinzo lwe-dimensional luqala ixesha elide ngaphambi kokuba umngundo ugalelwe
Uninzi lweentsilelo kwizindlu zoxinzelelo oluphezulu lwevalvu okanye iisilinda zempompo yepiston zibuyela emva kwingcambu enye: ukungangqinelani kwe-microstructure kwiibhetshi eziphathwe ubushushu. Siye sayibona ngokuphindaphindiweyo-amacandelo adlula ukuhlolwa kwe-CMM kwindawo yokushisa, emva koko i-warp ngexesha lenkonzo ngenxa yoxinzelelo olushiyekileyo lokupholisa okungalinganiyo ekugayweni kwesanti okanye ukwahlula okuziinkozo kwi-feedstock ephantsi. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke intsimbi kunye nentsimbi yokuphosa iqala ngoqinisekiso lwemathiriyeli ekrwada eqinisekisiweyo-hayi nje izatifikethi zokusila, kodwa uhlalutyo lokwenyani lwento enyibilikayo. Sijonga ukulingana kwekhabhoni, umxholo we-delta ferrite, kunye nokuchaphazeleka kwe-intergranular corrosion ngaphambi kokugalelwa. Yiloo ndlela esibamba ngayo ±0.02 mm ukunyamezela kwibhore ye-300 mm OD yesilinda-kungekhona njengesiphumo sovavanyo olunye, kodwa kwi-500-unit yemveliso iqhuba.
Apho ukuphosa kuphelela khona kunye nokuchaneka kuqala
Ukuboniswa kotyalo-mali kuzisa ijometri enemilo eshiyekileyo. I-Sand casting ibamba ubunzima kunye nobunzima be-thermal. Kodwa akukho nto ihambisa imiphezulu esebenzayo yokugqibela yodwa. Yiyo loo nto ukuhlanganiswa ngokuthe nkqo akulogama lokuthengisa apha-kuphela kwendlela yokulawula ukugqwetheka. Ipompo ye-cobalt-nickel alloy yendlu ephonswe kwisanti eboshwe nge-silica inokuzuza i-0.12 mm yokukhula kwe-thermal ngexesha lokufakwa kwesisombululo. Ukuba umatshini wenzeka kwiiveki kamva, ngaphandle koxinzelelo kwakhona okanye ukunciphisa uxinzelelo ngaphambi kokusikeka kokugqiba, oko kukhula kuguqulela ngokuthe ngqo kulwaphulo-mthetho lwe-GD&T kwiimpawu ezibalulekileyo zedatum. Indawo yethu ilandelelanisa unyango lobushushu, isiqabu soxinzelelo, kunye ne-multi-axis CNC machining ngaphakathi kweeyure ze-72-kwaye ilinganisa inyathelo ngalinye eliphakathi usebenzisa i-Zeiss CONTURA G2 CMMs ilinganiswe kwi-ISO 10360-2. Kwi-AMS 5387 cobalt alloy 6 components, sisebenzisa isiko le-carbide tooling ene-optimized chip-breaker geometry kunye ne-cryogenic coolant delivery-hayi ngenxa yokuba "iphambili," kodwa ngenxa yokuba izixhobo ze-HSS eziqhelekileyo ziphambukisa i-0.04 mm xa kusenziwa iprofayili ye-T800 ye-nozzles ye-alloy ene-0.8 mm ubukhulu bodonga.
Iindleko zangempela ze "non-standard" azikho kwisicatshulwa-kwi-rework
Abathengi bahlala bebuza: "Ngaba ungayenza le roller yeshaft esemgangathweni?" Into abangayithethiyo-kodwa into esiyiphandayo ngexesha lophononongo lobunjineli-ukuba inxalenye idinga ukusinda kwimithwalo ye-torsional shock ye-22 kN · m ngelixa ijikeleza kwi-45 rpm emoyeni waselwandle onetyuwa. Oko kutshintsha yonke into: ibakala lemathiriyeli (F22 vs. F22 CL3), umjikelo wonyango lobushushu (i-normalizing + tempering vs. quench & temper), ukugqiba komphezulu (Ra 0.8 µm umhlaba vs. Ra 0.4 µm honed), kunye nokupakishwa (umphunga-i-corrosion-inhibiting iphepha, hayi ukusonga iplastiki). Siyihlaba ifulegi kwangethuba-hayi ukunyanzela ucwangco, kodwa ukunqanda ukusilela kwebala. Omnye umxhasi ulondoloze i-$ 89,000 ngexesha lokuphumla ngokulungelelanisa i-angle ye-chamfer kwisihlalo se-valve yoxinzelelo ukusuka kwi-15 ° ukuya kwi-22 °-utshintsho olwanciphisa ukungcangcazela okubangelwa ukuhamba kunye nokwandisa ubomi benkonzo ukusuka kwiinyanga ezi-4 ukuya kwii-11. Olo lwazi luvela kwiseshoni yethu yokutolika ye-GD&T, hayi iphakheji yokuzoba.
Ukuthembela akuqinisekiswanga-kuyaqinisekiswa, ibhetshi ngebhetshi
Ukuthotyelwa kwe-ISO 9001 kukungenisa emnyango. Ukulandelelwa ngokupheleleyo kukugcina kwikhonkco lokubonelela. Yonke intsimbi yokugalela iinxalenye zefektri ibango lolawulo lomgangatho. Bambalwa abagcina amaxwebhu apheleleyo akwinqanaba lobushushu: inombolo yobushushu, umhla wokugalelwa, i-ID yesithando somlilo, ingxelo yovavanyo lokuqina, ukuqina kwemephu kuwo wonke ubungakanani becandelo, kunye neefayile zokuskena zeCMM ezigcinwe iminyaka eli-10. Siya. Xa i-OEM yaseYurophu icela uhlalutyo olupheleleyo lwe-microstructural ekuthunyelweni kwee-winch shafts zentsimbi engenasici, sinikezele ngemifanekiso ye-SEM ebonisa ukuhanjiswa kobungakanani beenkozo e-austenite-hayi nje "idibana ne-ASTM A351 CF8M." Oko kungafihlwayo akukhethi. Yindlela esilungelelanisa ngayo i-API 6A, i-EN 1515-2, kunye neemfuno ze-ASME B16.34 ngaphandle kokubekwa kuphicotho lomntu wesithathu kwi-PO nganye. Ukuhamba kwethu okubhityileyo akunikezeli ngokungqongqo-kuyayifakela: ukuhlolwa kwezinto ezingenayo, ukuqinisekiswa kwenqaku lokuqala, ukuhlolwa kwenkqubo kwi-20% kunye ne-70% yokugqitywa, kunye novavanyo lokugqibela olusebenzayo kwiibhentshi zovavanyo lwe-hydraulic ukuya kwi-700 bar.
Ukuba iprojekthi yakho elandelayo ifuna ukuchaneka kwentsimbi yokuphosa izixhobo zefektri-hayi nje ukuphosa, kodwa i-metallurgy elawulwayo, uzinzo oluqinisekisiweyo lwe-dimensional, kunye ne-zero-compromise traceability-qala ngolungelelwaniso lobugcisa, kungekhona amaxabiso ashithi. Iqabane elifanelekileyo alidibanisi nje neenkcazo. Baqikelela apho ezo nkcazo zisilela khona kumsebenzi wehlabathi lokwenyani.
