Iyo abajenjeri bagaragaje ibice bya sisitemu ya hydraulic, pompe zamavuta, cyangwa inteko ziremereye cyane, "uruganda rukora ibyuma rutunganya ibyuma" ntabwo ari ijambo ryishakisha gusa-nibisabwa bidashoboka. Igipimo cyimiterere munsi ya 500-bar igitutu. Microstructure ubunyangamugayo nyuma yubushyuhe bwamagare. Ubuso burangiza burwanya isuri yangiza. Ibi ntabwo ari kwihanganira-ni ibihe byo kubaho. Kandi barasaba ibirenze ibikoresho byo guta; bakeneye disipuline ya metallurgiki, gukomeza inzira, hamwe na comptabilite kuri buri ntambwe.
Impamvu Cobalt Amavuta Asaba Kurenza Imirongo isanzwe
Twabonye imishinga myinshi ihagarara mugihe utanga isoko afata AMS 5387 cobalt alloy nkicyuma gisanzwe 316. Igisubizo? Kuvunika mumazu ya pompe nyuma yamasaha 400 yo gukora. Uruzitiro rwagati rwagati rwimodoka. Kudasubirwamo gukomera indangagaciro mubice - nubwo itanura risa. Kubera iki? Kuberako cobalt-nikel superalloys itarwanya kwambara gusa-irwanya guhanura. Amashanyarazi yabo yubushyuhe ni kimwe cya kabiri cyibyuma. Kugabanuka kwabo gukomera ntabwo ari bibi. Imashini zabo zigabanuka 70% nyuma yo gukemura annealing.
Niyo mpamvu uruganda rukora ibyuma byukuri rushora imari mu gufunga ibintu bifatika - ntabwo ari umubare wibyiciro gusa, ahubwo amateka yubushyuhe bwuzuye ahujwe na buri casting. Babanje kwuzuza umusenyi uhuza T800 yo mu rwego rwo hejuru, ntabwo ari silika rusange. Bemeza igishoro cyokuzunguruka hamwe na mape ya thermocouple-ntabwo ari igihe gishingiye kubitekerezo. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri cobalt nozzle cyangwa plug itangirana nibikoresho byemewe byemejwe nabatanga Tier-1 - bikarangirana na raporo ya CMM yerekana ± 0,015 mm itandukanijwe hejuru yikimenyetso gikomeye, bigenzurwa mbere yo gutangira.
Kwishyira hamwe Vertical Ntabwo ari Buzzword-Nuburyo bwonyine bwo gufata GD&T
Abacuruzi bamwe batanga outsing casting, hanyuma bagura ubushobozi bwa CNC kumasoko yibibanza. Ibyo birema ibintu bitatu byananiranye: gutembera kurwego hagati yimashini zakozwe, imashini idahuye yubushyuhe, hamwe na zeru kugenzura ubusugire bwubutaka mbere yo kurangiza. Twasuzumye ibice amagana byanze aho casting yahuye na spec-ariko hejuru ya as-cast yarimo micro-porosity yagaragaye gusa nyuma yo gusya bwa nyuma.
Kwishyira hamwe kwukuri bisobanura kugenzura urunigi rwose: gutera ishoramari → kugabanya imihangayiko → gutunganya imashini nyinshi → gutunganya ubushyuhe nyuma yo gutunganya ubushyuhe → kurangiza neza neza. Kububiko bwa pisitori ya piston pompe, bivuze gufata uburinganire muri mm 0.008 kuri mm 300 z'uburebure - na nyuma ya nitriding. Kumuvuduko wumuvuduko, bivuze gukomeza kwibanda hagati yintebe yintebe hamwe na flange yo hanze yimbere muri mm 0,02 - hejuru yumubiri wibyuma bikozwe mumucanga hamwe nibikoresho bya cobalt trim. Ibi ntibishoboka udafite amakuru asanganywe ibikoresho, gahunda ihujwe, hamwe nitsinda rimwe ryiza risinya kuri buri ngingo yinzibacyuho.
Niki "Precision" bivuze mubyukuri mubikorwa byo gukina inganda (Kurenga Microns)
Baza injeniyeri icumi icyo "kwihanganira cyane" bisobanura, uzabona ibisubizo cumi na rimwe. Ariko mubikorwa byukuri-byukuri, kwihanganira ibintu ntibibaho mu bwigunge. Amazu ya mm 0,02 mm afite ikibazo gusa mugihe ubuso bwikigina cyo guhuza bugumye munsi ya Ra 0.4 µm - kandi niba coefficente yo kwagura ubushyuhe bwibikoresho byombi ihuza hagati ya 10% na -20 ° C kugeza kuri + 120 ° C.
Niyo mpamvu uruganda rukora ibyuma rutomoye rugomba gushyiramo kwemeza imikorere-ntabwo igenzurwa gusa. Umuyoboro wose wumuvuduko ukorerwa hydrostatike kuri 1.5 pressure umuvuduko wakazi. Buri winch center shaft roller ikoresha imbaraga zingana kugenzura kuri 3.500 RPM. Buri cobalt alloy nozzle inyura irangi-ryinjira * na * ultrasonic scanning yo munsi y'ubutaka bwa dendritic. Ibi ntabwo ari inyongera. Zubatswe mumabwiriza yakazi-hamwe na pass / gutsindwa ibipimo byanditse, bigenzurwa, kandi bigumana imyaka 10.
- CNC ibice byimashini: 5-axis ihuza inzira yimbere yimbere
- Ibigize Cobalt-nikel: AMS 5387 & T800 itunganya amavuta hamwe no kuvura ubushyuhe bwuzuye
- Ibyuma: EN-GJS-400-15 ibyuma byimyanda bifite igipimo cya spheroidisation> 95%
- Ibyuma & ingese: ASTM A351 CF8M hamwe no gupima ruswa hagati ya ASTM A262 Imyitozo E
Guhitamo Umufatanyabikorwa-Ntabwo ari ugutanga gusa
Amatariki yo gutanga. Igishushanyo kirahinduka. Ibikoresho bisimburwa. Ikitandukanya uruganda rukora ibyuma byizewe nuburyo ibyo bintu byakemuwe - atari niba bibaho. Twarebye abakiriya batakaza amezi mugihe umucuruzi yanze gusobanura GD&T mugihe cyo gusuzuma igishushanyo, ashimangira ati "ohereza gusa igishushanyo." Abandi batinze prototypes ibyumweru bitandatu kubera ko uruganda rudafite ubushobozi bwo kugenzura uburebure bwurukuta ku buryo bwo gushora imari ya 3D.
Umufatanyabikorwa mwiza atangirana nibitekerezo byakozwe - atari nyuma yo gusubiramo, ariko mugihe cyo gusuzuma. Bashyira ahagaragara ibishushanyo mbonera bitera igikonjo kumeneka muri cobalt. Basabye ubundi buryo bwo gutambuka kugirango bagabanye ububobere buke bwa pompe. Bemeza ibyemezo byibikoresho bihuye nibidukikije byakoreshejwe-byaba serivisi ya gaz isharira (NACE MR0175) cyangwa kurwanya ruswa yo mu nyanja (ISO 12944 C5-M).
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora muri ubu buryo - ntabwo ari politiki, ahubwo ni imyitozo ya buri munsi. Ikigo cyacyo cyujuje ISO gikora ibintu byose uhereye kuri prototypes imwe kugeza ku bicuruzwa biciriritse, hamwe na gahunda yubatswe ikurikirana umutungo wacitse mugihe nyacyo. Nta “amafaranga yo kwihuta.” Ntibitangaje kwishyurwa NRE. Ibikorwa byanditse gusa, ibisubizo bikurikiranwa, hamwe nibiganiro byubuhanga bitangirana na "Iki gice kizananirwa gute?" - ntabwo "Igiciro ni ikihe?"
Niba umushinga wawe utaha urimo umuvuduko ukabije, amazu ya pompe, cyangwa imyenda ikomeye, tangira ufite ikibazo: Ese uruganda rwawe rukora ibyuma rushobora gupima intsinzi muri micron - cyangwa mugihe gito hagati yo gutsindwa? Igisubizo cyerekana niba ibice byawe bimara amasaha 500 - cyangwa 5.000.
