Chosowa mwambo zitsulo kuponyera pafupi ine fakitale Thandizo-osati wothandizira chabe, koma wothandizana naye waukadaulo yemwe amamvetsetsa ma hydraulic pressure spikes, cobalt alloy brittleness, ndi chifukwa chiyani kuyimba kwa GD&T panyumba yapampu sikungafanane? Simukusaka ogulitsa makatalo. Mukuyang'ana wina yemwe wanyamula mphuno ya aloyi ya AMS 5387 m'manja, anayeza mawonekedwe ake ang'onoang'ono pansi pa SEM, ndikusintha makulidwe a chipolopolo * asanathire - chifukwa nthawi yapitayi, kusintha kwa khoma la 0.12 mm kunayambitsa kuphulika msanga muutumiki wakumunda.
Taziwonapo: A North America OEM idathamangitsira kukonzanso kwa nyumba ya pisitoni ya silinda kuti ikwaniritse nthawi yomaliza ya Tier 4. Opeza kwawo komweko adatchula milungu 14 - ndipo adapereka zida zitatu zokhala ndi porosity pamawonekedwe a valve. Kukonzekera sikunali kutumiza mwachangu. Kunali kulingaliranso kamangidwe ka mageti, kutenthetsa chikombole cha ceramic kufika pa 950 ° C, ndi kutsimikizira kayesedwe kolimba motsutsana ndi deta yeniyeni yojambula yotentha kuchokera kutsanulira. Ndiko kusiyana pakati pa "kuponya pafupi ndi ine" ndi mwambo zitsulo kuponyera pafupi ine fakitale yomwe imagwira ntchito pamphambano zazitsulo, geometry, ndi kudalirika kwa ntchito.
Chifukwa Chake "Pafupi Ndi Ine" Sikokwanira - Chomwe Chimafunika Kwambiri pa Kujambula Kwachangu
"Pafupi ndi ine" zimamveka bwino-mpaka wodzigudubuza wanu wa winch center shaft atalephera pa 72% katundu wa torque chifukwa mchenga woponyera njere sunagwirizane ndi vector torsional stress. Kuyandikira sikukutanthauza kanthu popanda mphamvu zinayi zomwe sizingakambirane:
- Chilango chakuthupi: Osati "zitsulo zosapanga dzimbiri" - koma S32750 duplex yotsimikizika yokhala ndi manambala otentha, zomwe zimatsimikiziridwa ndi ASTM A923, komanso kuyesa kwa dzimbiri kwa intergranular komwe kumachitika * m'nyumba * makina asanayambe.
- Kuphatikiza njira: Casting ndi CNC Machining pansi pa denga limodzi-chotero gulu lomwelo amalamulira shrink allowance, Machining katundu kugawa, ndi kutentha kupotoza chipukuta misozi
- Dimensional kukakamiza: Kuwunika kwa CMM * mutatha * kuchepetsa kupsinjika, osati kungopanga makina - komanso kuyeza kwa ndime zamkati momwe ma probe sangagwirizane.
- Kutsimikizira kogwira ntchito: Nyumba zoyezetsa kukakamiza ku 1.5 × kukakamiza kugwira ntchito, osati kungochokapo
Mashopu ambiri amchigawo amapambana pa imodzi kapena ziwiri. Ndi ochepa omwe amayendetsa zonse zinayi popanda kubwereketsa-ndipo ntchito iliyonse imawonjezera chiopsezo. Sitimapereka njira zoyambira. Makasitomala akatumiza chojambula cha T800 chopangidwa ndi cobalt chokhala ndi ± 0.005 mm kuzungulira mozungulira pa 12 mm bore, mainjiniya athu oyambira amawunikanso kapangidwe kake kokwera * ndipo* akatswiri athu amatsimikizira kukhazikika kwa zida - zonse asanatchule.
Kumene Oyambitsa Okhazikika Amadutsa malire Awo-ndi Momwe Timawatsekera
Ena amati: “Ingogwiritsani ntchito nyumba yosungiramo zinthu zapakhomo. Zoona—koma kokha ngati gawo lanu silikufuna AMS 5387 cobalt alloy, maziko a mpope opangidwa ndi mchenga okhala ndi mayendedwe ozizirira ophatikizika, kapena zopangira chitsulo zomwe zimafunikira ASTM A48 Kalasi 65–70 mphamvu zamakomezi *plus* malo osindikizira opangidwa ndi makina osungidwa ku Ra 0.4 µm.
Oyambira okhazikika samakhala ndi zida za T800 alloy ingots. Sayendetsa kutsimikizira kwa vacuum-arc remelt (VAR) pa kutentha kulikonse. Iwo samasunga kutsata kwazinthu zonse mpaka nambala ya ma electrode. Ndipo pafupifupi sanaphatikizepo kusanthula kwa GD&T mu gawo lopanga mawonekedwe-kotero mukamayamba kuponya, mawonekedwe a datum amasokonekera, kukakamiza kukonzanso kokwera mtengo kapena zidutswa.
Ife timatero. Chigawo chilichonse cha cobalt-nickel chimayamba ndi zida zotsimikiziridwa ndi mphero. Kuponyedwa kwa mchenga kulikonse kumawunikiridwa ndi ma radiographic pa ASTM E94. Chilichonse chopangidwa ndi makina chimatsimikizira kuti chimagwirira ntchito - osati kuuma kokha, komanso kusasinthasintha kwakutali m'malo 32. Umu ndi momwe timatumizira ma valve opanikizika omwe amayesa kuyesa kutopa kwa 100,000-popanda kulephera kumunda kamodzi m'miyezi 27 yapitayi.
Zotulutsa Zenizeni Zapadziko Lonse: Zomwe Mumalandila
Izi sizongoyerekeza. Nazi zomwe zimasiya malo athu a Qingdao sabata iliyonse:
- Zigawo za hydraulic system: Nyumba za Cylinder zokhala ndi nyumba zosungiramo mafuta zamkati zimaponyedwa ku ± 0.15 mm, kenako CNC-makina kuti agwire concentricity pakati pa bore ndi kukwera flange mkati mwa 0.02 mm
- Zida zamagetsi zamagetsi: Onboard winch center shaft rollers-mchenga-cast A48 Class 70 iron, kuchepetsa kupsinjika, kenaka kulowetsedwa-kuumitsa ku 58-62 HRC pamabuku osindikiza
- Zinthu zofunika kwambiri zamafuta ndi gasi: Cobalt alloy nozzles okhala ndi makulidwe a khoma otsika mpaka 1.8 mm, amatsimikiziridwa kudzera pamapu akupanga akupanga pamapu opindika
- Pampu misonkhano: Maziko a pampu osakhazikika okhala ndi mapazi ophatikizika ogwetsa-kugwedera-kuponyedwa, kutenthedwa ndi kutentha, komanso kumalizidwa mumndandanda umodzi wopanga
Palibe kulolerana kwa "zitsanzo-zokha". Palibe "zosintha zamapangidwe." Zomwe zimatsimikiziridwa pakupanga kwachitsanzo zimatsekeredwa mu dongosolo lowongolera njira zama voliyumu. Ichi ndichifukwa chake 68% yamakasitomala athu obwereza amayika ma liwiro apakati (50-500 pcs) mkati mwa masiku 90 kuchokera koyamba kubweretsa.
Masitepe Otsatira: Kuchokera Kujambula mpaka Kutumiza—Popanda Kungoganizira
Ngati muli ndi gawo lofuna kuponyedwa mwatsatanetsatane, makamaka mu aloyi a cobalt-nickel, chitsulo cholimba kwambiri, kapena zitsulo zosapanga dzimbiri zosapanga dzimbiri - yambirani apa:
- Gawani mafayilo anu a 2D/3D. Tidzabwezeranso malingaliro opanga mkati mwa maola 48-kuphatikiza malingaliro a gating, malipiro a masheya, ndi katsatidwe ka kutentha
- Tchulani zofunikira zogwirira ntchito: Kodi iyi ndi static load? Kuthamanga kwa njinga? Kukokoloka kwapamwamba? Timagwirizanitsa kusankha kwazinthu ndikukonza masitepe kuti agwire ntchito-osati zolemba zokha
- Tsimikizirani zofunikira zowunikira: Kutentha kwathunthu? Malipoti a mayeso a Mill? NDT zolemba? Timalemba zolemba mumayendedwe a ntchito-osati ngati zongoganizira
Simufunikanso "chiyambi pafupi ndi ine." Muyenera a mwambo zitsulo kuponyera pafupi ine fakitale zomwe zimagwira gawo lanu ngati zida zofunikira kwambiri - osati chinthu. Izi zikutanthauza kulankhula chinenero chanu: osati "chitsulo choponyedwa," koma "A48 Class 65 yokhala ndi pearlitic matrix yotsimikiziridwa ndi metallography." Osati "zopanda banga," koma "S32750 yokhala ndi ferrite 42-48% pa ASTM A923 Njira C."
Mlingo watsatanetsatane umenewo suchitika mwangozi. Zimachitika pamene metallurgists, mainjiniya oyambira, ndi opanga mapulogalamu a CNC amakhala m'chipinda chimodzi - ndikuwunikanso zojambula zonse pamodzi. Ndiwo muyezo wathu. Ndicho chimene chimapangitsa "pafupi ndi ine" kukhala ndi tanthauzo.
