Iyo abajenjeri bagaragaje ibyuma bitagira umwanda kubikoresho bya hydraulic, amazu ya pompe, cyangwa shitingi ya winch, ntabwo bahitamo gusa ibikoresho-bahitamo gushikama kumurongo munsi yumuvuduko wa bar-300, kurwanya ruswa mubidukikije byuzuyemo umunyu, hamwe nuburinganire bwa microstructural nyuma yo kuvura ubushyuhe. Niyo mpamvu guhitamo iburyo uruganda rukora ibyuma ntabwo bijyanye nigiciro kuri kilo. Byerekeranye na disipuline yimikorere, metallurgical traceability, hamwe nubushobozi bwagaragaye hamwe na AMS 5387 cobalt alloys, T800 superalloys, hamwe na 17-4PH cyangwa inzu ya duplex yuzuye.
Ibibazo byukuri byo gutunganya isi bisaba ibirenze imashini za CNC
Twabonye imishinga myinshi ihagaze kuri prototype-ntabwo ari ukubera ko igishushanyo cyatsinzwe, ariko kubera ko uwatanze isoko adashobora gufata mm 0.015 mm kuri pisitori ya pompe ya pisitori ifite insinga zimbere zahagaritswe hamwe numuyoboro ukonjesha. Imashini isanzwe idafite ibyuma ikora kumirongo na flanges. Ariko ibice byingenzi byingenzi-nkibikoresho byumuvuduko ukorera kuri 120 ° C mumavuta ya gaze na gazi cyangwa hagati ya shitingi ya shitingi ya moteri yimashini - bisaba kugenzura imashini ikora. Ntushobora gutanga umucanga guta umucuruzi umwe, ubushyuhe bwo kuvura undi, hanyuma ugaha icya gatatu kugirango urangize-axis nyinshi. Kugoreka ubushuhe birinjira. Ibinyampeke bitagenda neza. Kugereranya ibipimo birundanya.
Niyo mpanvu guhuza kwishyira hamwe bifite akamaro: kugenzura urunigi rwuzuye-uhereye kuri 316L cyangwa F51 yemewe yo kugenzura ibigega mbisi, binyuze mu gushora imari ya nozzles igoye, kugeza kuri 5-axis yo gusya hejuru yikimenyetso hamwe na passivisation ya nyuma-byemeza ko imashini isubirwamo. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri cobalt alloy plug itangirana na T800 ingot yemewe. Ibyuma byose bidafite ingese bikozwe mbere yo gusuka. Nta na kimwe kidasanzwe.
AMS 5387 na T800 ntabwo ari imibare yihariye-ni amanota yo gutsindwa ategereje kubaho
Abatanga ibicuruzwa bamwe bavuga "cobalt alloy" batagaragaje amanota. Ibyo ni bibi. AMS 5387 cobalt alloy 6 itanga ubukana bwihariye (38-45 HRC), guhuza ubushyuhe bwo guhuza (12.5 × 10⁻⁶ / ° C), hamwe no kurwanya isuri kumihanda yihuta cyane. T800 iragenda - igenewe ubushyuhe bugera kuri 800 ° C, hamwe no guhangana n’ibikurura imbaraga mu guteranya pompe ya turbine. Ariko iyi mashini ya alloys kuri 1/3 igipimo cyo kugaburira 304 idafite umwanda. Igikoresho cyo kwambara. Ubusugire bwubuso burasenyuka niba umuvuduko ukonje ugabanutse munsi yumubari 70 cyangwa gukomera kwa spindle bigufi.
Twabipimye: inzira yinzira itagenzuwe ikurikiranye kuri AMS 5387 nozzle yateje microcracking yo munsi y'ubutaka igaragara gusa munsi ya SEM. Igice cyatsinze igenzura-ariko cyananiwe guturika ku gipimo cya 92%. Ubushobozi nyabwo busobanura gukoresha amasomero yemewe yububiko bwibitabo, kugenzura imbaraga zo kugabanya mugihe nyacyo, no guhuza ububobere buke (Ra ≤ 0.4 µm) hamwe nubuzima bwumunaniro ukora. Ibyo ntibishobora kuganirwaho kubice byibyuma bitagira umuyonga abafatanyabikorwa bakora uruganda rukora pompe zo mu kirere.
Ubwiza ntibugenzurwa-bwubatswe, bikurikiranye
"ISO yemejwe" isobanura bike keretse ubonye uko ikora buri munsi. Kuri iki kigo, fagitire zinjira zidafite ibyuma zibona verisiyo ebyiri: PMI spectroscopy + tensile yipimisha kuri buri bushyuhe. Mugihe cyo gutunganya, cheque ya CMM ibaho nyuma yo gukomeretsa, kurangiza, no gutambuka kwanyuma - bitarangiye. Ibyingenzi? Gupimwa n'ibipimo byo mu kirere byahinduwe buri munsi. Ifishi yumutwe? Kugenzurwa na optique ya profilometero, ntabwo ucomeka wenyine.
Traceability ntabwo ari impapuro-ni code ya laser ya QR kuri buri mubiri wa valve uhuza nigiti cyambere cyashonze, umurongo wo kuvura ubushyuhe, na raporo yubugenzuzi bwa nyuma. Mugihe OEM yu Burayi yasabye GD&T kwemeza umusingi udasanzwe wa pompe, itsinda ryatanze ibishushanyo bisobanuwe byerekana neza aho intego za datum zashizwe kumubiri kuri casting - n'impamvu ibyo bibanza byagabanije gutandukana guterwa no guterwa mugihe cyo gutunganya. Urwo rwego rwo gukorera mu mucyo rugabanya ibiciro bya NRE 30% ugereranije.
Kwizerwa bitangira kera mbere yuko igice cya mbere cyoherezwa
Gutanga ibintu bihoraho bishingiye kubintu bitatu: imiyoboro ihamye yo gutanga ibikoresho, ibihe byateganijwe, hamwe nibitekerezo byakozwe mbere. Twafashije abakiriya kwirinda ibishushanyo mbonera byerekana urukuta rw'uburebure bwurukuta rwatera kugabanuka gukabije muri 17-4PH - cyangwa kumenya GD&T guhamagarwa bisaba gage gakondo birenze ubushobozi bwa CMM. Ntabwo ari "inkunga yubuhanga." Nukugabanya ingaruka zubatswe mugice cyo gusubiramo.
Kubakiriya bashakisha ibyuma bitagira umwanda kumasoko yisi yose - yaba sisitemu yo mumazi ya hydraulic yo muri Amerika ya ruguru, pompe yo mu Budage OEM, cyangwa abubaka ibikoresho byo mu nyanja yo mu majyepfo y’iburasirazuba bwa Aziya - agaciro kari mu nyandiko zisubirwamo mu byiciro, ntabwo ari igiciro gito. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yibanda kubitera urushinge: guhuza metallurgjique, ubudahemuka bwa geometrike kumurongo utoroshye, hamwe na zeru zeru kubishobora. Kuberako iyo ibice byawe bifunze igitutu 300-bar, ntamahirwe ya kabiri.
