Akatswiri akamatchula magawo a ma hydraulic system, mapampu akumunda wamafuta, kapena mawitchi olemera kwambiri, "fakitale yolondola kwambiri" sikuti ndi mawu osaka chabe - ndizofunikira zomwe sizingakambirane. Dimensional bata pansi pa 500-bar pressure. Kukhulupirika kwapang'onopang'ono pambuyo pa mikombero 10,000 yokhudzana ndi abrasive. Kusasinthika kwazitsulo pamagulu 200 a mayunitsi. Izi sizolinga zamalingaliro. Ndi zizindikiro zatsiku ndi tsiku-zomwe takumana nazo ku North America valve OEMs, ophatikiza magalimoto a engineering aku Germany, ndi omanga mapampu aku Singapore.
Chifukwa Chake Cobalt Alloys Amafuna Zambiri Kuposa Makina a CNC Okha
Zigawo za faifi ya cobalt-makamaka AMS 5387 ndi T800-grade-zimalephera mosadziŵika bwino pamene makina opangira makina amasuntha ndi 0.5%. Tidaphunzira izi movutirapo paulendo woyendetsa ndege wa 2022 wothamangitsa nyumba ya valve yapansi pa nyanja: kung'ung'udza pang'ono kumawoneka kokha pambuyo pa njinga yamoto yotentha, komwe kumabwereranso kukusakhazikika kwa chip panthawi yodutsa movutikira. Kuyambira pamenepo, fakitale yathu yolondola kwambiri imayika kuwunika kwa ma spindle torque nthawi yeniyeni pa 5-axis Machining Center-osati ngati chinthu chamndandanda, koma ngati chipata cholowera. Palibe gawo lomwe likupita kumapeto pokhapokha kusiyana kwa torque kumakhala mkati mwa ± 2.3% kudutsa katatu motsatizana.
Kulangidwa kumeneku kumakhudzanso kupeza chuma. Sitikuvomereza ma certs okha. Ingot iliyonse ya cobalt alloy imalowa m'nyumba musanayambe kuponya. Chifukwa chiyani? Chifukwa kufufuza sulfure pamwamba pa 0.008% kumayambitsa kung'ambika kotentha m'milomo yopyapyala-ngakhale gululo "lidutsa" ASTM A992. Gulu lathu lothandizira limapanga ma profailo ochizira kutentha ndi ogulitsa zinthu, kusintha nthawi zonyowa potengera miyeso yeniyeni ya tirigu, osati ma chart a ng'anjo wamba.
Kuphatikiza Koyima Komwe Kumawongolera Kusinthasintha
Otsatsa ambiri amatulutsa kunja, kukonza makina, ndi chithandizo cha kutentha. Izi zimapanga magwero atatu osiyana a dimensional drift. Pamalo athu a Qingdao, zopangira ndalama zimapangidwira pamndandanda womwewo wa DMG Mori NT womwe umamaliza gawo lomaliza. CMM yomweyo imatsimikizira onse obiriwira-boma komanso misonkhano yomaliza. Labu yomweyo ya metrology imayang'anira zida zonse tsiku lililonse motsutsana ndi masters otsatiridwa ndi NIST.
Timawona kusiyana kwakukulu mu nyumba za silinda za pisitoni. Makasitomala amatumiza ma callout a GD&T kufuna ± 0.005 mm malo enieni pamadoko 12 a ulusi. Pamene kuponyera ndi makina kumachitika m'masitolo osiyana, zolakwika zochulukirapo nthawi zambiri zimagunda ± 0.018 mm. Mayendedwe athu ophatikizika amafikira ku ± 0.004 mm - chifukwa pulogalamu ya CNC imalozera mwachindunji malo omwe amajambulidwa poyang'ana nkhani yoyamba. Palibe zongoganizira. Palibe mipukutu yokonzanso.
Kuwongolera uku ndikofunikira kwambiri kwa ma geometri omwe si wamba. Kuyitanitsa kwaposachedwa kwa cholozera cha shaft cham'mphepete mwa nyanja kunafunikira mizere 7° ya helical 320 mm m'mimba mwake, youmitsidwa kufika 58 HRC. Ochita nawo mpikisano adatchula masabata 14 omwe ali ndi chiopsezo cha 30%. Tinapereka m'milungu 8-pogwiritsa ntchito choyikapo cha carbide chomwe chinasunga umphumphu m'mphepete mwa mphindi 42 za kudula mosalekeza. Deta ya moyo wa zida tsopano ikukhala mu nkhokwe yathu yamkati, yolembedwa ku AMS 5387, mtundu wa kuuma, ndi kuchuluka kwa madzi ozizira.
Ubwino Womwe Simayima pa Malipoti Oyendera
Ndondomeko zathu zowunikira zimatsata ASME Y14.5-koma pitirirani. Chigawo chilichonse chovuta chimakhala ndi mapasa adijito: mbiri yojambulidwa nthawi yomwe ikuwonetsa kusanthula kwazinthu zomwe zikubwera, kusanthula kwa CMM m'magawo atatu, kuwerengeka kwapang'onopang'ono kusanachitike komanso kupitilira, ndi zotsatira zoyeserera (mwachitsanzo, kutayikira kwa helium pa bar 10). Izi si za zisudzo zotsata. Umu ndi momwe tidadziwira kulephera kwa chisindikizo pamaziko a pampu: choyambitsa chinali kupsinjika kotsalira kochokera ku kuzizira kosiyana panthawi ya annealing-osati kulakwitsa kwa makina. Tidasintha kuzungulira kwa kuzimitsa, kutsimikiziridwa ndi mapu a X-ray diffraction, ndikuchepetsa kulephera kwamunda ndi 92%.
Timasunga kuwunika kokwanira mpaka kuchuluka kwa kutentha kwa chinthu chilichonse chopangira - ndikuchilumikiza ndi zotsatira zonse zoyendera. Ngati kasitomala akuwonetsa vuto, timakoka mbiri yonse ya digito mkati mwa masekondi 90. Ayi, "tibwerera kwa inu." Ayi "molingana ndi ndondomeko yathu." Ma data okha, masitampu anthawi, ndi chidziwitso chotheka.
Kudalirika Kumayamba Asanayambe Kudula Kwambiri
Fakitale yolondola kwambiri imapangitsa kuti anthu akhulupirire osati panthawi yopanga, koma pakuwunikanso uinjiniya. Timayika ziwopsezo zopanga kupanga mwachangu: "Uku makulidwe a khoma la 0.15 mm pa nozzle ya cobalt alloy yanu kudzafuna zolemba za EDM; nthawi yotsogolera imawonjezeka ndi masiku 11." Kapena: "Mapeto anu a Ra 0.2 µm panyumba yachitsulo yopangidwa ndi mchenga amafunikira kukonzanso - apa pali kukhudzidwa kwamitengo poyerekeza ndi Ra 1.6 yokhala ndi zokutira zokongoletsedwa ndi nkhungu." Sitikunena "inde" ku mapangidwe osatheka. Timati "izi ndi zomwe zimagwira ntchito, chifukwa chake, ndipo apa pali kusinthanitsa."
Njirayi yapangitsa kuti nthawi yobereka ikhale yokhazikika pa 98.7% pa miyezi 36 yotsatizana, ngakhale panthawi yachisokonezo chapadziko lonse lapansi. Bwanji? Pokhala ndi strategic buffer stock of certified AMS 5387 billets ndi T800 master alloys, komanso kusunga mapangano amitundu iwiri pazida zazikulu zodulira. Osati monga kusungira katundu - koma monga kuchepetsa chiopsezo kumatengera njira zolephera zomwe taziwona m'munda.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amapanga magawo pomwe kulephera sikungachitike. Ngati ntchito yanu ikufuna kutsimikizika kokulirapo mu ma cobalt alloys, kukhulupirika kwamapangidwe pamapangidwe oponderezedwa kwambiri, kapena kudalirika kwamapampu ofunikira kwambiri - mufunika zambiri kuposa wogulitsa. Mufunika fakitale yolondola kwambiri yomwe imachita kulolerana kulikonse ngati lonjezo.
