Mainjiniya akafuna zida zachitsulo zolondola zomwe zimapulumuka kupsinjika kwambiri, kutha kwamphamvu, kapena malo owononga kwambiri, makamaka m'makina amadzimadzi, zida zamafuta ndi gasi, kapena zida zapampopi zolemera kwambiri, samangoyang'ana * chilichonse choyambira. Amayang'ana a fakitale yoponya mchenga yotayika ndi ulamuliro wotsimikiziridwa pazitsulo, geometry, ndi microstructure-osati yomwe imagwiritsa ntchito ndalama ndi mchenga ngati zosankha zosinthika.
Tawona mapulojekiti ambiri akuchedwa chifukwa wogulitsa adalonjeza "kuponyedwa mwatsatanetsatane" koma adapereka magawo omwe ali ndi chimanga chosagwirizana, oyenda pang'onopang'ono pambuyo potenthetsa kutentha, kapena zowonongeka zomwe zimakakamiza kukonzanso kokwera mtengo. Chifukwa chake? Malo omwe amayendetsa ntchito ngati njira yokhayokha-yosiyana ndi makina, sayansi yazinthu, ndi kutsimikizira magwiridwe antchito. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timapanga sera yotayika (ndalama) ndi kuponyera mchenga osati ngati njira zina-koma ngati zida zowonjezera mumayendedwe amodzi, ophatikizika molunjika. Umu ndi momwe timagwirizira kulekerera kwa ± 0.05 mm pamilomo ya aloyi ya cobalt ndikusunga kulimba kofanana panyumba zapampu za AMS 5387-ngakhale makulidwe a khoma la 200 mm.
Chifukwa Chake "Factory Yotaya Mchenga Wotayika" Ndi Nthawi Yosocheretsa-Ndipo Zomwe Mukufunikira
Mawu akuti "fakitale yotaya mchenga yotayika" amasokoneza njira ziwiri zosiyana: kuponya ndalama (pogwiritsa ntchito zigoba za ceramic zomangidwa mozungulira sera) ndi kuponya mchenga (pogwiritsa ntchito mchenga womangika). Palibe chomwe chimalowa m'malo mwa chinacho, ndipo palibe chomwe chimapereka mwatsatanetsatane chokha. Kulondola kwenikweni kumawonekera pokhapokha onse athandizidwa ndi kuthekera kosagwirizana ndi zitatu:
- Kukonzekera kwa alloy yotsimikiziridwa ndi zinthu-makamaka ma cobalt-nickel superalloys ngati T800 ndi AMS 5387, pomwe kupatuka pang'ono mu kaboni kapena chromium kumayambitsa kusweka kwanthawi yayitali podzaza cyclic;
- Kupitilira kwapang'onopang'ono pakusintha kwa makina kupita ku makina-Kutanthawuza kuti mapangidwe a nkhungu amachepa, kukonza makina kumafanana ndi malo osungiramo zinthu, ndipo kuyendera kwa CMM kumatsimikizira zonse zojambulidwa zosaphika ndi zomalizidwa motsutsana ndi dongosolo lomwelo la GD&T;
- Ntchito traceability-osati manambala a batch okha, koma zolemba zonse zomwe zimalumikiza gawo lililonse ndi chipika chake chosungunula, curve yochizira kutentha, mapu olimba, ndi zotsatira zomaliza zoyeserera.
Ndizo zenizeni kumbuyo kwa malo athu ogwirizana ndi ISO ku Qingdao. Sitimapereka kusanthula kwazitsulo. Sitivomereza "near-net-shape" ngati chowiringula chodumpha kuunika kwa gawo loyamba. Makasitomala akatumiza chithunzi cha nyumba ya silinda ya pampu ya pisitoni, mainjiniya athu amayankha pasanathe maola 48—osati ndi mawu, koma ndi ndemanga yofotokoza: “Fillet radius iyi igwira porosity pokhapokha titasintha khomo; nazi kayesedwe kake.” Ndizochitikira-osati malonda.
Kumene Ogulitsa Ambiri Amalephera—Ndi Momwe Timatsekera Kusiyana
Ena amatsutsa kuti kuponya mchenga sikungafanane ndi kuyika ndalama mwatsatanetsatane. Ena amati ma aloyi a cobalt ndi "ovuta kwambiri kuponya modalirika." Mawu onsewa ndi oona - ngati mukugwira ntchito ndi maziko a cholinga chambiri. Koma muzochita, zolephera nthawi zonse zimakhala zandondomeko, osati zaukadaulo.
Tatsata magawo 127 okanidwa pama projekiti 19 a kasitomala chaka chatha. 3% yokha idalephera chifukwa cha zolakwika zakuthupi. Opitilira 68% adatsata zomwe amayembekeza zolakwika: zojambula zolembedwa "monga-kumaliza" koma zimafunikira malo osindikizira; kulolerana kumagwiritsidwa ntchito pazinthu zomwe sizingatheke kuziwona popanda magawo owononga; kapena zizindikiro zochizira kutentha zolembedwera katundu-osati ma microstructures.
Yankho lathu sikukankhira mmbuyo-ndikulowetsamo kale. Pulojekiti iliyonse imayamba ndikuwunikanso zojambulajambula. Timayimitsa mikangano ya GD&T tisanayambe kugwiritsa ntchito zida. Timatsimikizira ma core prints a shakeout integrity - osati kulondola kwa dimensional. Ndipo timayesa kuyesa ndi njira za NDT zodziwika ndi kasitomala (RT, UT, kapena zolowera) pamayunitsi asanu oyamba - osati makumi asanu oyamba. Ichi ndichifukwa chake 92% ya maoda athu apakati amatumiza munthawi yake, osathawa mopitilira muyeso poyang'ana komaliza.
Kulondola Kwambiri Padziko Lonse: Kuchokera Kusankha kwa Aloyi mpaka Gawo Lomaliza
Tengani pulagi ya aloyi ya cobalt yomwe imagwiritsidwa ntchito pamapampu a jakisoni a subsea. Iyenera kusindikiza pa 15,000 psi pamene ikulimbana ndi kupsinjika kwa sulfide. Kuponyera mchenga wokhazikika sikungakhale ndi njere yabwino yofunikira kuti musatope. Kupanga ndalama kwanthawi zonse kumatha kuyambitsa kuchepa kwapang'onopang'ono pamunsi mwa flange. Yankho lathu? Kukonzekera kwa Hybrid: Ponyani malo osindikizira ofunikira pogwiritsa ntchito zida za ceramic zokhotakhota zamkati, kenaka sinthani kupita ku mchenga wowongoleredwa wa flange wokwera-opangidwa munjira imodzi pogwiritsa ntchito zida za vacuum zomwe zimasunga bata.
Zopangira zimabwera zotsimikiziridwa ndi AMS 5719, ndi zolemba zonse za mbiri ya kutentha. Pambuyo poponya, maere aliwonse amawerengedwa molunjika pa spectrometry ndi kuyesedwa kwamphamvu pa ASTM E8. Zigawo zomaliza zimayesa kuyesa kwa helium pa 1 × kuthamanga kwa ntchito - ndipo timasunga deta yonse kwa zaka 10.
Izi sizongoyerekeza. Ndimomwe tidaperekera zida zapampu za 4,200 AMS 5387 kwa opanga makina a Tier-1 hydraulic system ku Europe-ndi zolephera za zero m'miyezi 36 yogwirira ntchito pobowola kunyanja.
Kusankha Wokondedwa Wanu Sizokhudza Mayina Omwe Akuchita-Ndi Za Chilango Chophatikizidwa
A fakitale yoponya mchenga yotayika chizindikiro sichikuwuzani chilichonse ngati fakitaleyo imamvetsetsa momwe kulimba kwa cobalt kumakhudzira kudyetsa kwapakati-kapena chifukwa chomwe mbali ya 0.3 mm yojambula imakhala yofunika kwambiri pakuponyera kwa T800 kuposa chitsulo chosapanga dzimbiri 316.
Chofunikira ndi chakuti ngati ogulitsa anu ali ndi tcheni chonse: zopangira zinthu ndi mphero zowunikiridwa ndi ogulitsa, zowonera m'nyumba, makina a CNC osinthidwa kukhala ma datamu, ndikuwunika komaliza kolumikizidwa mwachindunji ndi magwiridwe antchito - osati mabokosi oyendera.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. sichigulitsa ntchito zoponya. Timapereka zida zachitsulo zofunika kwambiri - zopangidwa, zotsimikizika, komanso zotsatirika kuchokera ku zitsulo zosungunuka kupita ku zida zoyikika. Ngati pulojekiti yanu yotsatira ikufuna kukhulupirika kwapang'onopang'ono, kusasinthika kwapang'onopang'ono pamagulu onse, kapena kuphatikiza kopanda msoko pakati pa makina opangira ndi olondola kwambiri - mufunika zambiri kuposa maziko. Mukufunikira mnzanu yemwe amachitira chigawo chilichonse ngati kuti kulephera kwake kungayimitse mpope, kuyimitsa winch, kapena kutseka chitsime.
