Akatswiri akamanena za kuponyedwa kwa mchenga pazigawo zazitsulo zolimba kwambiri—makamaka m’ma hydraulic systems, zida zamafuta ndi gasi, kapena pamisonkhano yapampu yolemetsa—samangosankha njira. Akusankha mnzawo amene amamvetsetsa momwe chimanga chimakhudzira moyo wa kutopa, momwe nkhungu imakhudzira kubwerezabwereza, komanso chifukwa chake kulolerana kwa 0,15 mm pa nyumba ya silinda ya cobalt si pempho-ndichofunikira chosakambitsirana. Ndipamene zochitika zenizeni zimalekanitsa ogulitsa okhoza ndi owona mchenga kuponyera maziko fakitale abwenzi.
Chifukwa Chake Kuponya Mchenga Kumapambanabe Pazigawo Zofunika Kwambiri Pamafakitale
Ena amaganiza kuti kuponya mchenga kumangochitika zokha. Koma taziwona zikupereka chipambano chobwerezabwereza pamene njira zina zimalephera: zoponyera zitsulo zamagulu akuluakulu zomwe zimafuna kukana kutenthedwa kwa kutentha mu maziko a pampu; zitsulo nyumba ndi njira kuzirala mkati zosatheka makina pambuyo kuponyera; zida zosapanga dzimbiri zomwe zimafunikira mphamvu ya isotropic kudutsa zigawo zokhuthala. Chofunikira ndikuwongolera - osati kungowonjezera kutentha kapena nthawi yogwedeza, koma pamchenga wonse: kusasinthasintha kwa mchenga wobiriwira, kuyanjanitsa kwapakati, kapangidwe kake ka kayendedwe ka laminar, ndi kuzungulira kwapambuyo kwa kupsinjika komwe kumatsimikiziridwa ndi mapu a strain gauge.
Mu pulojekiti ina yaposachedwa, European OEM inkafunika matupi 42 opanikizika mu ASTM A351 CF8M. Wowagulitsira m'mbuyomu adaphonya ma callouts a GD&T pamabowo atatu okwera - zomwe zidasokoneza msonkhano woyeserera womaliza. Tidachigwira potsimikizira kujambula, tidasintha mawonekedwe a cope ndi 0.8 °, ndikuwonjezera pini yachiwiri yolumikizira nkhungu. Zotsatira: zero rework kudutsa mayunitsi 120. Kulowerera kumeneko sikungatheke popanda kuphatikizika kokhazikika-kuchokera kusakaniza mchenga mpaka CNC kumaliza kupanga pansi komweko.
Kumene Ukatswiri Wazinthu Umagwirizana ndi Chilango cha Njira
Ma aloyi a cobalt-nickel ngati AMS 5387 ndi T800 samayankha pamachitidwe amtundu wamba. Malo awo osungunuka kwambiri, kutsika kwamadzimadzi, komanso kung'ambika kwaukali kumafuna njira zofananira: kulimba kwa ma binder ratios, nkhungu zomwe zimatenthedwa kale kuposa 250 ° C, ndi kuziziritsa koyendetsedwa bwino komwe kumayang'aniridwa kudzera pazipinda zomangira za thermocouples. Tathira 1,700 kg ya T800 m'miyezi 18 yapitayi-ndipo gulu lililonse limakhala ndi kutsatiridwa kwathunthu: nambala ya kutentha, lipoti lowunikira, ndi zithunzi zapang'onopang'ono zowonetsa kutalikirana kwa manja kwa dendrite pansi pa 25 µm.
Chilango chimenecho chimapitirira kugwiritsira ntchito alloy. Pazitsulo zachitsulo zomwe zimagwiritsidwa ntchito popanga makina opangira ma winch center shaft rollers, timatsimikizira chiwerengero cha graphite nodule (ASTM E2567) ndi chiŵerengero cha ferrite / pearlite * isanayambike * makina akuyamba. Chifukwa chiyani? Chifukwa kuchuluka kwa 5% pearlite kumawonjezera nthawi yopera ndi 37% ndikudula moyo wa zida pakati. Timapima—osati kungolingalira.
Kodi “Kulondola” Kumatanthauza Chiyani Kwenikweni Pochita
Kulondola pakuponya mchenga sikungofuna kuthamangitsa kulekerera kwa ma micron pazigawo zazikulu. Ndi za kulosera. Kuthekera kwathu: ± 0.3 mm pazinthu mpaka 600 mm, ± 0.5 mm pazigawo zopitilira 1,200 mm-ndi malipoti ankhani yoyamba otsimikiziridwa ndi CMM akuphatikizidwa popanda mtengo wowonjezera. Koma chofunikira kwambiri ndi malingaliro athu: ngati kujambula kwanu kumafuna kumaliza kwa 12.5 µm Ra pachibowo chopangidwa ndi makina, tikuwonetsa ngati malo otayira adzafunika 2.1 mm kapena 3.4 mm yochotsa katundu - komanso momwe izi zimakhudzira kuchepa kwa malipiro ndi kuyika kokwera.
- Ma valve opanikizika: Malo ogwirizana ndi GD&T, otsimikiziridwa ndi gaging ya mpweya komanso kuyesedwa kotuluka pa 1.5 × kugwira ntchito
- Nyumba za silinda za pampu ya piston: Kukhazikika kwapakati komwe kumasungidwa mpaka 0.025 mm TIR kudutsa 450 mm kutalika
- Non-standard cobalt alloy nozzles: Kusiyanasiyana kwa makulidwe a khoma kumayendetsedwa mkati mwa ± 0.18 mm pazigawo zochepa za 8 mm
Sitikuwona kuponya ndi kukonza ngati madipatimenti osiyana. Ndi magawo otsatizana a njira imodzi-kotero wopanga mapulogalamu a CNC amawunikanso as-cast CT scan asanalembe njira yoyamba. Umu ndi momwe mumapewa kupeza porosity pansi pa malo osindikizira ovuta pambuyo pa maola 14 akugaya.
Kusankha Mnzanu Amene Mudzapereke—Osati Malonjezo Okha
A mchenga kuponyera maziko fakitale ayenera kuyankha mafunso atatu musanasaine PO: Kodi angakugwiritsireni ntchito molimbika kwambiri pa geometry yovuta kwambiri * yopanga *, osati muzojambula? Kodi ali ndi ziphaso zawo zakuthupi-kapena amadalira mapepala ogulitsa? Ndipo kupatuka kukakhala kosiyana, kodi amagawana zomwe zimayambitsa (zipika za mchenga, mipiringidzo yosungunula, mamapu a X-ray) kapena kungopereka mawonekedwe owongolera?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito pansi pa ISO 9001:2015 yokhala ndi ndondomeko zoyendera zolembedwa pamagawo aliwonse oponya. Chigawo chilichonse chamafuta chimatsimikiziridwa, gawo lililonse lotenthetsera limayikidwa, gawo lililonse lomalizidwa limawunikidwa pansi pa 10 × magnification. Timatumikira makasitomala ku North America, Europe, ndi Southeast Asia-osati kudzera mwa ma broker, koma kudzera pamisonkhano yachindunji: kutanthauzira kwa GD&T, mayankho akupanga mkati mwa maola 48, ndi zosintha zapamlungu zokhala ndi zithunzi za zochitika zazikuluzikulu.
Tsogolo la kuponya mchenga molondola liri mumayendedwe osakanizidwa - pomwe kuponyera kumatanthawuza kuchuluka kwa geometry ndi kukhulupirika, ndipo makina amapereka mawonekedwe ogwirira ntchito komanso zolimba. Izi zimafuna kuzindikira kozama kwazitsulo, kulumikizana kolimba, komanso kulolerana zero pazongoganiza. Ngati polojekiti yanu yotsatira ikufuna magawo omwe akugwira ntchito-osati oyenerera-yambani ndi kumveka bwino kwa ndondomeko, osati zolemba zamtengo wapatali.
