Pamene mainjiniya amatchula a fakitale ya valve cage, sikuti amangoyitanitsa magawo-akusankha bwenzi lomwe lingathe kugwira ± 0.01 mm kulolerana pansi pa 350 bar pressure, kusunga umphumphu wa microstructural pambuyo pa chithandizo cha kutentha, ndikupereka kutsata kwathunthu kwa zinthu za ASME Gawo VIII kapena API 6A kutsata. Ndicho chenicheni cha ntchito-osati chinenero cha malonda.
Tawona ntchito zambiri zikuyimitsidwa chifukwa wothandizira "woyenerera" sakanatha kugwira ma callouts a GD&T pamakhola a cobalt-nickel valve pakutsimikizika komaliza kwa CMM. Pampu imodzi ya OEM yaku North America idataya milungu isanu ndi umodzi pomwe wogulitsa wawo wam'mbuyomu adatanthauzira molakwika zofunikira za AMS 5387 za kukula kwambewu - zomwe zidapangitsa kusweka msanga pampando. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timachitira khola lililonse la valve ngati njira yogwirira ntchito: kusindikiza pamwamba pa geometry, kufananitsa kukulitsa kwamafuta, komanso kugawa nkhawa sizofunikira. Iwo amapangidwa mu gawo loyamba la makina.
Malo athu ogwirizana ndi ISO ku Qingdao amayang'anira kutsata kwathunthu-kuponyera mchenga kwa ASTM A48 Class 35 zitsulo zotuwa zotuwa, kutsirizitsa njira zamkati zamkati za CNC, ndi chithandizo cha kutentha pambuyo pa makina ovomerezeka ndi kuuma kwa mapu ndi zitsanzo za metallographic. Sitimapereka njira zofunikira. Pamene opanga ma hydraulic ku Europe amafunikira 220 mm m'mimba mwake ya piston pampu ya silinda yokhala ndi mabowo olimba a 42CrMo4 ndi malo osindikizira a nitrided, tidawongolera kusasinthika kwazitsulo kuchokera pa billet yaiwisi mpaka kumapeto - palibe kusiyana kwa batch-to-batch ngati kuya kapena kulimba kwapakati. Kuphatikizika koyima kumeneku kumathetsa kulephera kwa mawonekedwe pakati pa zoyambira ndi makina ogulitsa makina.
Zosankha zitatu zaukadaulo zimasiyanitsa kupanga khola lodalirika la ma valve ndi makina azinthu:
- Chilango chopeza zinthu: Timangogwiritsa ntchito ma aloyi opangidwa ndi cobalt (T800, Stellite 6, AMS 5387) ovomerezeka kuti apereke malipoti oyesa mphero okhala ndi kutsimikizika kwathunthu kwazinthu zamakina ndi mankhwala -osati mayina amagiredi pa ma invoice. Gulu lathu laukadaulo limagwirizanitsa ogulitsa pogwiritsa ntchito ASTM E112 kusanthula kukula kwambewu ndi kuyesa kwaukali kakang'ono ka ASTM E384 m'magawo osiyanasiyana.
- Kukonzekera koyambirira kwa geometry: Asanadule zitsulo, mainjiniya athu amatengera kupotoza kwa kutentha panthawi yochepetsera kupsinjika kwa nyumba zazikulu zoponyedwa. Pa dongosolo laposachedwa la winch center shaft roller, tidasintha njira zokhotakhota kuti tilipire zida zomwe zidanenedweratu za 0.018 mm-kuchotsa kukonzanso komwe kukanachedwetsa kubweretsa kwa masiku 11.
- Kuyendera kophatikizidwa-osawonjezeredwa: Khola lililonse la valavu limayendera katatu CMM: pambuyo pokonza movutikira (kutsimikizira ndalama zogulira katundu), mukamaliza kukonza (GD&T yonse), ndipo mutatha kuyeretsa komaliza (kuti muwone kuwonongeka kwa kasamalidwe). Optical profilometry imayang'ana malo osindikizira Ra mitengo yotsika mpaka 0.2 µm - yotsimikiziridwa motsutsana ndi milingo yotsimikizika yamakasitomala, osati malire anthawi zonse.
Ena amaganiza kuti cobalt alloy valve cages amafuna zida zachilendo. Chowonadi ndi chakuti, kupambana kumadalira kubwerezabwereza-osati zachilendo. Timayendetsa zida zofanana pamakina asanu a HAAS VF-6 a nozzles a AMS 5387, okhala ndi kuyang'anira katundu wa spindle komanso kulipira zida zodzichitira. Pamene wothandizira mafuta aku Southeast Asia adayitanitsa mapulagi 47 a cobalt aloyi okhala ndi mipando 12 °, tidapeza zokolola zoyambira 99.4% - osati chifukwa cha "AI yapamwamba," koma chifukwa oyendetsa athu amabwerezanso malangizo ofufuza maola 8 aliwonse ndikulowetsa pH yoziziritsa nthawi iliyonse.
Mtengo suchepetsedwa ndi kudula ngodya. Imayendetsedwa ndikuchotsa kusatsimikizika. Ndemanga yathu ya uinjiniya imaphatikizanso mayankho opangidwa mkati mwa maola a 48: kuyika zigawo zokhala ndi mipanda yopyapyala zomwe zimakonda kucheza, kuwonetsa ma radiyo ena kuti apewe zizindikiro zowotcha za EDM, kapena kulimbikitsa kusintha kwa katsatidwe ka kutentha kuti tipewe ma warpage mu ma geometries asymmetric. Makasitomala m'modzi adachepetsa mtengo wokwanira wa projekiti ndi 22% titalimbikitsa kusintha kuchoka pa T800-cast-cast kupita ku sand-cast + 17-4PH yolondola kwambiri—popanda kusokoneza chiwopsezo chophulika.
A fakitale ya valve cage imapeza chidaliro ikatumiza zolembedwa ndi gawo lililonse: ma cert, mbiri ya kutentha, malipoti a CMM okhala ndi zolakwika, ndi zithunzi zowunikira zomwe zikuwonetsa kutsatiridwa kwapamwamba. Timachita izi pamaoda aliwonse - ngakhale ma prototypes. Chifukwa m'makina othamanga kwambiri a hydraulics kapena subsea control system, khola si gawo. Ndilo malire pakati pa ntchito ndi kulephera.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikupitiliza kukonzanso njira zake zopangira makina osakanizidwa a mavavu am'm'badwo wotsatira-makamaka kutsata kusinthasintha koyenda bwino (<± 1.5%) ndi moyo wotalikirapo wautumiki m'malo otayirira abrasive. Cholinga sichinasinthidwe: pangitsa kukhazikika kwa mawonekedwe kukhala odziwikiratu, magwiridwe antchito azitsulo kuti athe kutsimikizika, komanso nthawi yobweretsera zisakanizidwe.
