Pamene makina anu a hydraulic akufunikira valve yopanikizika m'milungu itatu-osati miyezi itatu-ndipo makina anu opangira makina opangira magetsi amayenera kupulumuka maulendo 10,000 othamanga kwambiri, ma timene amtundu wamba akugwa. Taziwonapo: makasitomala amaletsa zoyeserera atadikirira masiku 42 kuti apeze nyumba imodzi yokhala ndi mchenga, koma adangopeza kuti ndalama zopangira makina sizikugwirizana ndi nkhungu. Izi si vuto - ndi kusagwirizana kwa ndondomeko. A mofulumira mchenga kuponyera fakitale sikungochepetsa nthawi yotsogolera. Imafotokozeranso zomwe zingatheke pamene kutulutsa molondola kukugwirizana ndi changu chogwira ntchito.
Chifukwa chiyani "Kufulumira" Sikuti Kungotsatsa - Ndi Chilango cha Njira
Kuponya mchenga mwachangu sikungothamangira. Ndizokhudza kuchotsa masitepe osakhala amtengo wapatali ndikusunga kukhulupirika kwazitsulo ndi kukhulupirika kwapang'onopang'ono. Pamalo athu a Qingdao, "kufulumira" kumatanthauza: 7-12 masiku ogwira ntchito kuyambira kujambulidwa kovomerezeka kupita ku nkhani yoyamba-palibe chindapusa, palibe zosintha, palibe kunyengerera pa AMS 5387 cobalt alloy alloy structure kapena T800-based microhardness (48-52 HRC as-heat-treated). Timakwaniritsa izi potseka ma levers anayi omwe ambiri amanyalanyaza:
- Kutsimikizika kwadongosolo la digito musanayambe kupanga matabwa-Chilipiriro chocheperako cha CMM chopangidwa m'mafayilo a STL, osaganiziridwa pakupanga nkhungu
- Mchenga wobiriwira woyenerera kale umaphatikizana ndi mabokosi apakati oyendetsedwa ndi chinyezi-palibe kusinthika kwa batch-to-batch pakuthekera kapena kulimba kowuma
- Njira yofananira: Kukonzekera kwa CNC ndi kukonza chithandizo cha kutentha kumayamba *pamene* nkhungu ikuphwanyidwa
- Palibe malupu okonzanso: Kujambula kulikonse kumakhala ndi gawo lonse la radiography + mapu owuma pamwamba * asanamangidwe * makina opangira makina
Uku sikuthamanga pamtengo wowongolera. Ndi liwiro * lololedwa * ndi kuwongolera. Wofuna chithandizo atatitumizira zojambula za pampu zokhala ndi ma callout a GD&T a ± 0.05 mm flatness pa mbale yoyambira 420 mm, tidayesa kuyesa ndi ma thermocouples ophatikizidwa kuti apange mapu olimba - kenaka tidasintha khomo * isanayambike * kutsanulira koyamba. Zotsatira zake? Nkhondo ya Zero. Kuvomerezedwa kwa nkhani yoyamba pa tsiku la 9.
Kumene Kuponya Mchenga Mwachangu Kumalephera (Ndi Chifukwa Chake Fakitale Yathu Imapambana)
Ena anganene kuti kuponya mchenga mwachangu sikungathe kulolerana molimba pazithunzi zovuta ngati pisitoni pampu ya silinda. Ndi zolondola - ngati mukugwiritsa ntchito mchenga wamba, ma cores odzaza manja, ndi makina oponyedwa positi kuti apulumutsidwe. Koma si choncho zoona mofulumira mchenga kuponyera fakitale imagwira ntchito.
Timaponyera mbali zachitsulo ndi zitsulo zokhala ndi makina ophatikizika: malo osindikizira, ma bore, ndi nkhope za flange zomwe zimafuna ≤0.03 mm kuchotsa katundu. Bwanji? Pophatikiza kuumba kosasunthika kosasunthika ndi kuwunika kachulukidwe ka mchenga munthawi yeniyeni (pogwiritsa ntchito ukadaulo wa nyukiliya yolinganizidwa ndi ISO 22988), ndikutsimikizira jiometri ya nkhungu yokhala ndi ma triangulation a laser *pambuyo* kugwedezeka koma *pamaso* kutentha. Deta imadyetsa mwachindunji mu CNC toolpath planner-chotero kukanika kumathandizira kutsika kodziwikiratu kwa kutentha, osati kusuntha kwachisawawa.
Pazigawo za cobalt-nickel-monga ma nozzles a AMS 5387 omwe amawonekera ku 650 ° C cyclic thermal shock-timagwiritsa ntchito nkhungu zamchenga zokutira ndi zingwe zozizirira. Palibe kuzimitsa mpweya. Palibe kusweka. Maere aliwonse amakhala ndi kutsata kwathunthu: chipika chosungunuka, kuthira kokhotakhota, mawonekedwe oziziritsa, ndi scan ya EDS yotentha-kutentha yotsimikizira kusakhalapo kwa gawo la sigma.
Sikuti Onse "Ofulumira" Ali Ofanana - Apa ndi Zomwe Zimasuntha Singano
Nthawi yotsogolera imachepa pokhapokha ngati gawo lililonse lakonzedwa kuti lizigwira ntchito, osati kungojambula. Ichi ndichifukwa chake kuphatikiza kwathu koyima ndikofunikira:
- Kuponya ndi kukonza pansi pa denga limodzi: Palibe kuchedwa kwa kutumiza, palibe kusamvetsetsana kwa data pakati pa foundry ndi shopu yamakina
- Chitsimikizo cha zinthu m'nyumba: Timayesa ma billets a aloyi a T800 omwe akubwera kuti agawire carbide-osati chemistry-pogwiritsa ntchito SEM/EDS asanasungunuke
- Kuyang'anira kogwira ntchito komangidwa: Kuyesa kwa valve iliyonse yothamanga kumayenda pa 1.5 × kukakamizidwa kovotera * isanathe * yomaliza pamwamba
- Palibe "standard" magiredi: Sitigulitsa "A395 ductile iron." Timasunga QT600-3 yokhala ndi nodularity yotsimikizika> 85% ndi pearlite 92-96% - chifukwa ndizomwe zimakhazikika pama hydraulic manifolds
Kota yatha, European OEM idafunikira mayunitsi 47 a chodzigudubuza cha winch center shaft chosakhazikika — geometry yovuta kwambiri kuti ipangike pakatikati, yayikulu kwambiri kuti ingagulitsidwe. Opikisana nawo adalemba masabata 18. Tinapereka nkhani yoyamba m'masiku 11, kuitanitsa kwathunthu mu 22. Osati chifukwa tinagwira ntchito kumapeto kwa sabata. Chifukwa mzere wathu woponyera mchenga umagawana zida ndi malo athu a 5-axis mphero - ndipo mainjiniya athu apamwamba amapezana ndi okonza mapulani.
Kusankha Mnzanu Woponya Mchenga Wofulumira—Yang'anani Pakalendala
Mawu a masiku 10 sakutanthauza kanthu ngati gawolo lifika ndi porosity mu ukonde wonyamula katundu kapena kuzama kwa mlandu wosagwirizana pambuyo poumitsa. Funsani mafunso awa musanasaine:
- Kodi mungandiwonetse malipoti atatu omaliza a CMM a geometry yofananira - ndi komwe kupatuka kwakukulu kunachitika?
- Kodi mumatsimikizira kukula kwa nkhungu * pambuyo * kugwedezeka, kapena kuganiza kuti chitsanzocho chinali chabwino?
- Kodi matenthedwe amakonzedwa * ndi* kutsanulira - kapena kumangirizidwa pambuyo pake?
- Kodi protocol yanu yakukana kwa microstructure anomalies ndi iti? Kukonzanso? Zakale? Kusanthula kwachiyambi komwe adagawana ndi kasitomala?
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yankho lililonse limakhala lolembedwa, lowerengeka, komanso lolumikizidwa ndi magwiridwe antchito. Sitigulitsa maola oponya. Timapereka zida zachitsulo zogwira ntchito-panthawi yake, kuti titchule, zowoneka bwino. Chifukwa mu ma hydraulics othamanga kwambiri, mavavu amafuta & gasi, kapena ma drivetrains oyendetsa galimoto, "kuthamanga" kumangofunika ngati kulinso. kulondola.
