Pamene nyumba ya pampu ya hydraulic imaphwanyidwa pansi pa 350-bar pressure-kapena cobalt alloy nozzle imalephera pambuyo pa maola 420 a ntchito ya gasi wowawasa - akatswiri samaimba mlandu mapangidwe. Amazitengera ku chigamulo chimodzi: yemwe anali naye metalcasting adagwira ma geometry ovuta, microstructure, ndi kukhazikika kwa dimensional.
Apa ndipamene kupanga zodziwikiratu kumasiya kukhala chinthu chamtengo wapatali ndipo kumakhala mgwirizano wantchito. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tazionera tokha kukonzanso mavavu 178 a pampu, 92 m'malo mwa mawitchi akunyanja, ndi magulu 36 AMS 5387 a aloyi a cobalt aperekedwa kwa ophatikiza ma hydraulic system a Tier-1. Kulephera kulikonse komwe tasanthula kudagawana chifukwa chomwechi - osati kusachita bwino, koma kuphatikiza kolakwika kwa makina opanga makina.
Chifukwa chiyani "Kulondola" mu Metalcasting Kumatanthauza Kuposa Kulekerera Kwambiri
Kulekerera kolimba kokha sikutsimikizira ntchito. Kukhuthala kwa khoma la ± 0.02 mm pa nyumba ya silinda ya pampu ya pistoni sikukutanthauza kanthu ngati mawonekedwe a mchenga ali ndi shrink porosity pafupi ndi fillet yopanikizika kwambiri. Kapena ngati kupsinjika kotsalira kuchokera kuziziritsa kosagwirizana kumasokoneza flange pamwamba pa CNC kuyang'ana.
Tidazindikira izi panthawi yotsimikizika ya 2022 ya OEM yamagalimoto aukadaulo a EU. Wogulitsa wawo woyambirira adakumana ndi ma callout onse a GD&T pamapepala - koma 31% ya nyumba zidalephera kuyesa hydrostatic pa bar 400. Gulu lathu lidapanga mapu olephereka: nthiti yofikira 1.8 mm moyandikana ndi doko lolowera mafuta. Funso silinali kukonza zolakwika. Zinali zokhazikika kulimba kwa mlingo kusagwirizana mu nkhungu yamchenga, kukulitsidwa ndi kusintha kosalamulirika kwapakati.
Njira yothetsera? Tidakonzanso makina ojambulira *ndi* ndikuwonjezera kolala yokwera yoziziritsa-ndiyeno kutsimikizira kulimba kofananira ndi data yeniyeni yofanizira yochokera mukuthira. Zotsatira: kulephera zero kudutsa mayunitsi 12,400. Kuyika zitsulo mwatsatanetsatane kumayamba musanayambe kutsanuliridwa ladle yoyamba.
Maluso Atatu Osakambitsirana a Mishoni-Critical Castings
Sizinthu zonse zoyambira zomwe zimatha kutsekereza kusiyana pakati pa kukhulupirika kwazitsulo ndi geometry yogwira ntchito. Izi ndi zitatu zomwe timayesa mwamphamvu- tisanatchule gawo limodzi:
- Kulunzanitsa kwazinthu: Kuponyera ma aloyi a cobalt-nickel ngati T800 kapena AMS 5387 sikutanthauza kuthira zitsulo zotentha. Imayang'anira kapangidwe ka tirigu kudzera mu kutentha kwapamwamba kwambiri (1420-1445 ° C), kutentha kwa nkhungu (220-240 ° C), ndi mitengo yoziziritsa pambuyo pothira. Timalowetsa gawo lililonse-ndikugwirizanitsa ndi kutalika kwamphamvu ndi kuuma kwapakati pa kutentha kulikonse.
- Dimensional chain control: Kuponyedwa kwachitsulo kumatha kugwira ± 0.3 mm ngati kuponyedwa, koma ndizopanda ntchito ngati chomaliza chopangidwa ndi makina chimafuna ± 0.015 mm. Timamanga milu yololera yomwe imapangitsa kuti shrinkage, kupotoza kwa zida zamakina, ndi kukulitsa matenthedwe panthawi ya chithandizo cha kutentha-zonse zimatsimikiziridwa ndi makina a CMM pazigawo zitatu: monga-cast, theka-malize, ndi yomaliza.
- Kufufuza kwathunthu-osati manambala amtundu wokha: Makasitomala akamanena kutha kosagwirizana kwa mapulagi a aloyi a cobalt, timafunikira zambiri kuposa kuchuluka kwa kutentha. Timakoka zipika za ng'anjo, zolemba zam'mchenga zomangira, nthawi yokhalamo mu uvuni, komanso chinyezi chambiri pakumanga nkhungu. Kutsata kwazamalamulo kumeneku kunalepheretsa kulephera kubwereza pulojekiti yopopera mafuta aku Southeast Asia kotala lapitalo.
Mtengo weniweni wa "Standard" Metalcasting Solutions
Ogula ena amasankha kuponya zotsika mtengo kutengera mtengo wa pakg. Koma pochita, amalipira kwina:
- Kupanganso zinyalala: 12-19% kutayika kwa zokolola pazitsulo zovuta zachitsulo pamene malipiro a makina sakukonzedwanso kuti asinthe.
- Kulephera kumunda: Pampu imodzi yosweka yazitsulo zosapanga dzimbiri idawononga ndalama zogwiritsira ntchito madzi mumsewu waku North America $217,000 panthawi yopuma mwadzidzidzi - osawerengera anthu olowa m'malo.
- Kuchedwa kwa mapangidwe: Popanda mayankho oyambilira akupanga, 68% yamakasitomala athu oyamba amafunikira kusintha kwa geometry. Timayimitsa madera omwe ali pachiwopsezo, monga nthiti zopyapyala zokhala ndi mipanda pansi pa 2.3 mm kapena ma angles ochepera pansi pa 0.8°—panthawi yowunikira, osati zida zitadulidwa.
Njira yathu yopangira makina osakanizidwa imadula nthawi yotsogolera ndi 34% pafupifupi. Chifukwa chiyani? Chifukwa timapanga makina osindikizira ovuta kwambiri * tisanalandire kutentha komaliza—kupewa kupotoza komwe kumapangitsa kukonzanso magawo omwe amalizidwa.
Metalcasting Imakula Popanda Kupereka Umphumphu
Kupanga kwapakatikati kumawonetsa zofooka zosawoneka muzowonetsa. Kutenthetsa njinga kudutsa 500 kuthira kumasintha magwiridwe antchito amchenga. Kugwedezeka kwa nkhungu kumaunjikana. Kutopa kwa opareshoni kumakhudza kusasinthika kokhazikika.
Timalimbana ndi izi ndi njira zowongolerera zogwirira ntchito: makina ozungulira a nkhungu amalumikizidwa kuti azitha kuchiritsa mitengo, makina opangira ma jigs okhala ndi mayankho okhazikika, komanso kuwunika kwa akupanga pa 100% yazitsulo ndi zitsulo zosapanga dzimbiri zopitilira 15 kg. Pa ma aloyi a cobalt, timawonjezera kusanthula kowoneka bwino pamoto wachitatu uliwonse kuti titsimikizire kuchuluka kwa nickel-chromium-molybdenum mkati mwa ± 0.15% yazinthu zina.
Izi sizowonjezera-injiniya. Ndimomwe timaperekera zokolola zoyamba 99.82% pamatupi okakamiza a valve-posungabe kutsata kwazinthu zonse mpaka pagawo la ingot ndi ID ya ng'anjo yosungunuka.
Precision metalcasting imathetsa mavuto enieni: kupewa kutayikira kowopsa m'makina opanikizika kwambiri, kukulitsa moyo wautumiki m'malo owonongeka, kupangitsa mapangidwe opepuka popanda kusokoneza mphamvu. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga mphamvu imeneyo-osati monga malonda, koma ngati ndondomeko yolembedwa, yowerengeka, yobwerezabwereza. Pamene gawo lanu likugwira ntchito pomwe kulephera sikungatheke, zitsulo ayenera kukhala maziko—osati ganizo lomaliza.
