Pamene mainjiniya ndi oyang'anira zogula amafufuza a fakitale ya kampani yopanga mchenga zomwe zimapereka kukhazikika kwapakati, kusasinthasintha kwazitsulo, komanso kutumiza pa nthawi yake-osati kungojambula chabe-nthawi zambiri amakumana ndi vuto lomwelo: ogulitsa ambiri amawona kuponya mchenga ngati chinthu. Koma m'ma hydraulic manifolds, mapampu othamanga kwambiri, kapena ma winch shafts akunyanja, kulolerana kwa 0.15 mm kapena kusagwirizana kwapang'onopang'ono "sikuyandikira mokwanira." Ndi kulephera kwamunda.
Chifukwa Chake Kutaya Mchenga Kufunikabe—Ngati Wachita Bwino
Kuponyera mchenga kumakhalabe njira yotsika mtengo kwambiri pazigawo zapakati, zovuta-geometry ferrous ndi zopanda chitsulo kupitirira 5 kg-makamaka pamene makulidwe a khoma amasiyana, zitsulo zamkati ndizofunikira, kapena zovuta za alloy zimathetsa kufa kapena njira zapakati. Koma kudalirika kumadalira zinthu zitatu zomwe mafakitale ochepa amazilamulira nthawi imodzi: kutsatiridwa kwazinthu zopangira, kukhulupirika kwa nkhungu pansi pa kugwedezeka kwamafuta, komanso kutsimikizika kwapambuyo pakupanga makina asanayambe. Tawona mapulojekiti ambiri akuchedwa chifukwa wogulitsa "woyenerera" adalandira ASTM A48 Class 35 imvi yachitsulo popanda kutsimikizira kuwerengetsa kwa nodule ya graphite - kapena kudumpha ma radiography asanayambe makina pa gulu la cobalt-alloy valve lomwe likupita kukatumikira gasi wowawasa.
Katswiri Wozama wa Aloyi Ndiwosakambirana
Sikuti kuponya mchenga kuli kofanana. Mapangidwe opangidwa kuchokera ku ductile iron kapena carbon steel amatsata kutsika kodziwikiratu komanso mapindikira ochepetsa kupsinjika. Cobalt-nickel alloys ngati AMS 5387 kapena T800? Amafuna makonzedwe osiyanasiyana olowera, kuzizira pang'onopang'ono, komanso kutsata kolondola kwa kutentha - kapena mutha kusweka pang'onopang'ono pakutembenuka kwa CNC komaliza. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Akatswiri samangotsanulira zitsulo. Amatsimikizira gulu lililonse la T800 motsutsana ndi ASTM F962 pazakudya za cobalt ndi kukula kwambewu; amagwiritsa ntchito ma thermocouple arrays ophatikizidwa mu nkhungu kuti alembe mbiri zenizeni zolimba; ndipo amasunga zolemba zoyambirira kwa maola 72 asanakonzekere kuti atsimikizire kumasuka kwa nkhawa. Ichi ndichifukwa chake nyumba zawo za silinda za pampu ya piston zimakwaniritsa Cpk> 1.67 pamabotolo ovuta-ndipo chifukwa chake ma nozzles a AMS 5387 cobalt alloy amapulumuka mizungulire 12,000+ m'malo otsekemera amatope.
Kuphatikiza Koyima Kumathetsa Mipikisano Yeniyeni Yapadziko Lonse
Mashopu ambiri opangira mchenga amapereka zoponya kwa akatswiri amisiri ena. Izi zimapanga malo osawona: porosity yobisika pansi pa makina opangira makina, kupanikizika kotsalira komwe sikunathetsedwe musanamalize, kapena kusagwirizana kwa GD&T pakati pa zojambula zojambula ndi mapulogalamu a CNC. QINGDAO QIANGSENYUAN imagwira ntchito pansi pa denga limodzi - kuponyera, ma CNC amitundu yambiri (kuphatikiza ma contouring a 5-axis kwa maziko a pampu), chithandizo cha kutentha, ndi kumaliza pamwamba ngati zokutira za HVOF kapena passivation. Makasitomala atatumiza chojambula cha injini ya winch center shaft roller yokhala ndi ± 0.025 mm yozungulira pa 280 mm OD, gululo lidalengeza kuti mawonekedwe oyambira a mchenga angayambitse kuchotsedwa kwamasheya. Anakonzanso dongosolo, kusintha zisindikizo zapakati, ndikuyesa kuyesa-kenako kutsimikizira zozungulira *pambuyo* mokhotakhota koma *asanamalize* kugaya. Zotsatira: kukonzanso zero, kutsata kwathunthu pamutu woyamba.
Ubwino Siuwunikiridwa Mkati-Umamangidwa, Pang'onopang'ono
Zolemba zogwirizana ndi ISO sizikutsimikizira magwiridwe antchito. Amachita chiyani? Kuwunika kolembedwa pazigawo zisanu ndi chimodzi zosakambitsirana: ma certs azinthu omwe akubwera (ndi kutentha kwa nambala ya kutentha), kutsimikizira kuuma kwa nkhungu wobiriwira, matabwa a kutentha kwa shakeout, kuuma kwamakamaka pambuyo pa kutentha, kusanthula kwa CMM kwa ma datamu ovuta * pamaso * ndi * pambuyo * machining, ndi kuyezetsa komaliza kogwira ntchito - ngati matupi oyeserera a 1.5 × Lipoti lirilonse likugwirizana ndi dongosolo logulira loyambirira ndi kukonzanso zojambulazo. Palibe kuchotserapo. Makasitomala ku North America ndi ku Europe amalandira zolemba zonse za digito: 3D scan scan ikuwonetsa ngati-cast vs. final geometry, malipoti owunikira ma spectral batches a alloy batches, ndi zolemba zoyendera zosindikizidwa nthawi. Ngati mbali ina yalephera, gwero lake limawonekera—osati kukwiriridwa m’malingaliro.
Kusankha Mnzanu Wotsatira Woponya Mchenga—Zomwe Mungafunse Tsopano
- "Ndiwonetseni ma AMS 5387 anu atatu omaliza - kukula kwake kwenikweni kunali kotani, ndipo munatsimikizira bwanji?" (Ngati angotchula mphamvu zokhazikika, chokanipo.)
- "Kodi mutha kugwira Cpk ≥ 1.33 pa kulolerana kwa 0.05 mm kwa mawonekedwe * ndi * opangidwa m'nyumba?" (Ngati akuzengereza kapena kunena kuti "zimadalira kujambula," ndondomeko yawo sikhazikika.)
- "Kodi nthawi yanu yayitali bwanji yopangira mchenga - kuchokera ku PO mpaka kutumiza nkhani yoyamba?" (Pansi pa masiku 25 chizindikiro chophatikizana; pamasiku 45 nthawi zambiri amatanthauza kupanga mapangidwe akunja kapena chithandizo cha kutentha.)
A odalirika fakitale ya kampani yopanga mchenga sichimalonjeza ungwiro. Imayembekezera njira zolepherera - ndipo imapanga kuzindikira, kukonza, ndi kupewa mu gawo lililonse. Ndiko kusiyana pakati pa kulandira ma castings ... ndi kulandira chidaliro.
