Zigawo zamafakitale zogwira ntchito kwambiri sizimalora kunyengerera-makamaka ngati zikugwira ntchito pansi pa 30,000 psi hydraulic pressure, 650 ° C kutulutsa mpweya wotulutsa mpweya, kapena kuvala kosalekeza kwa abrasive m'zida zapansi pa mafuta. Ichi ndichifukwa chake mainjiniya ku North America, Germany, ndi Singapore akuchulukirachulukira kudumpha ogulitsa ma generic ndikupita patsogolo ufa zitsulo fakitale okhoza kupereka osati zigawo zokha-koma zovomerezeka mwazitsulo, zotsimikiziridwa ndi ntchito. Taziwonera tokha: mphuno ya aloyi ya cobalt ikulephera kuzungulira 42,000 pakuyesa jekeseni wothamanga kwambiri-osati chifukwa cha mapangidwe, koma chifukwa chakuti mbiri ya woperekayo inadutsa ± 8 ° C kudutsa magulu. Ndiko kumene kulondola kumathera ndipo chiopsezo cha ntchito chimayamba.
Chifukwa chiyani "Zotsogola" Zikutanthauza Zambiri Kuposa Ufa Wabwino Kwambiri
Kupita patsogolo kwenikweni kwa zitsulo za ufa kumayamba kalekale musanakanikize kapena kuziziritsa. Zimayamba ndi traceability wakuthupi mpaka nambala ya batch yosungunuka, mpweya woyendetsedwa ndi mpweya wochepa ≤10⁻⁶ atm, ndi chithandizo cha kutentha kwapambuyo pa sinter chovomerezeka ku AMS 2750E pyrometer tolerances. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timachitira mbali iliyonse ya AMS 5387 cobalt alloy ngati isindikiza chotchinga chapansi pa nyanja. Izi zikutanthauza kuti palibe kachulukidwe wobiriwira wobiriwira, palibe kukula kwambewu kosaneneka pa HIP, komanso kusasunthika kopitilira ± 0.015 mm pambuyo pochepetsa kupsinjika-kutsimikiziridwa ndi CMM sikani pagawo lililonse, osati zitsanzo zoyambirira.
Tawonapo mfundo zitatu zolephereka mobwerezabwereza pazigawo za PM zomwe amaperekedwa ndi makasitomala: (1) kusagwirizana kwa pore morphology kumayambitsa kutopa msanga kuyambika mu nyumba za silinda za piston; (2) zigawo za oxide pamwamba kuchokera ku sintering yopanda vacuum yomwe imayambitsa dzimbiri la galvanic mu maziko a pampu yazitsulo zosapanga dzimbiri; (3) kaboni yotsalira yomangirira yomwe imatsogolera ku microcracking panthawi yomaliza ya makina a T800 alloy center shaft rollers. Yankho lathu? Mayendedwe ophatikizika ophatikizika - chiphaso cha zinthu zopangira → kutsekereza koyendetsedwa → vacuum sinter-HIP → kulondola kwa 5-axis CNC → ASTM E112 kutsimikizika kwa kukula kwambewu-kuchitidwa pansi pa denga limodzi ndi kutsata kwathunthu kwa digito.
Kumene Ma Casting-Machining Hybrid Processes Amapereka Real ROI
Akatswiri ena amaganiza kuti zitsulo za ufa zimalowa m'malo mwa kuponyera. Izo sizima—izo zimakwaniritsa izo. Kwa ma geometries ovuta ngati ma valve oponderezedwa okhala ndi ndime zotuluka mkati ndi ma flanges okwera kunja, timaphatikiza kuyika kwa ndalama zokhala ndi mawonekedwe oyandikana ndi ukonde ndi PM pazosindikiza zovuta. Chifukwa chiyani? Chifukwa kuponyera kumapereka kukhulupirika kwadongosolo pamitengo yotsika pazigawo zazikulu, pomwe PM imakwaniritsa kachulukidwe ka 99.8% ndi Ra ≤0.4 µm pamwamba kumaliza komwe kusindikizira kumachitika. Mmodzi wa ma hydraulics aku Europe OEM adadula mtengo wokwanira pa valavu iliyonse ndi 22% pogwiritsa ntchito njira yosakanizidwa iyi-palibe kukonzanso, kusayenerera, kungopanga mapu anzeru.
Izi sizongoyerekeza. Timayendetsa mizere yopangira mchenga ndikuyika ndalama motsatira malo athu a PM-osati ngati madipatimenti osiyana, koma monga ma node olumikizana mu network imodzi yopanga. Makasitomala akatumiza zojambula za GD&T za injiniya wodzigudubuza wa winch center shaft roller, gulu lathu limawunikira ngati magazini yonyamula iyenera kusindikizidwa ndi kumalizidwa (kuti isavale) pomwe gawo la spline limapangidwa ndi makina (kuti azitha kulimba). Chigamulocho chimadalira mamapu enieni onyamula, osati zolemba zamakalata.
Kuwongolera Kwabwino Komwe Ma Engineers Amakhulupirira
"Wotsimikizika ku ISO 9001" amapezeka patsamba lililonse la ogulitsa. Chofunikira ndi zomwe zimachitika mbali ikalephera kuyendera. Pamalo athu a Qingdao, chigawo chilichonse chokanidwa chimayambitsa ndondomeko yoyambitsa mizu: kusanthula kwazitsulo zazitsulo, mapu a SEM-EDS, ndi kubwereza mbiri ya kutentha. Kota yatha, tidatsata mapulagi a aloyi a cobalt okhala ndi kuuma kosagwirizana mpaka pa chowongolera chimodzi cha thermocouple calibration mu ng'anjo ya sinter - yokonzedwa mkati mwa mphindi 90, ndikutumiza ziro zomwe zidakhudzidwa. Ulamuliro umenewo umagwira ntchito pokhapokha ngati khalidwe silili dipatimenti - limakhala pamndandanda wa tsiku ndi tsiku wa wogwiritsa ntchito aliyense.
- Kutsimikizira kwazinthu zomwe zikubwera: Kusanthula kwa Spectrometric + kuyesa kwa ultrasonic kwa voids yamkati
- Kuwunika kwakanthawi: Kudula mitengo kwanthawi yeniyeni ndi alamu yokhayokha pa O₂> 5 ppm
- Kuyanika komaliza: CMM + optical profilometry + kuyesa kuthamanga kwa magwiridwe antchito pa API 6D kapena ISO 5211
- Kutsatiridwa: Mbiri yakale ya QR yomwe imapezeka kwa makasitomala-kuphatikiza ma cert, zipika za ng'anjo, ndi malipoti oyendera
Zomwe Mungafunse Musanayanjane ndi Advanced Powder Metallurgy Factory
Osafunsa "Kodi mungapange gawo ili?" Funsani m'malo mwake: "Mumatsimikizira bwanji kuti sintering ibwerezabwereza pamizere 10,000?" Kapena: "Ndiwonetseni malipoti anu atatu omaliza a AMS 5387 osagwirizana ndi momwe mudawatsekera." Amphamvu kwambiri patsogolo ufa zitsulo fakitale mayankho ndi deta, osati timabuku. Adzagawana kusiyanasiyana kwawo kwa kachulukidwe (athu: ± 0.15% kudutsa ma kilogalamu 500), pafupifupi kuuma kwawo kwapambuyo pambuyo pa sintering (Ra 1.2–1.8 µm, kutha kutha mpaka 0.3 µm ndi kutsirizitsa kwachiwiri), ndi ubale wawo wautali kwambiri wamakasitomala (zaka 14, ndi kulephera kwa pampu ya ziro pagawo la coba).
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imamanga mbali zomwe zimakhala zosindikizidwa, kukhala zolimba, ndikukhalabe muutumiki-chifukwa ntchito siimayesedwa mu malipoti a labu. Imayesedwa munthawi yake, nthawi yokonza, komanso mtengo wathunthu wa umwini pazaka 15 zogwira ntchito. Ndiwo muyezo womwe timapanga mainjiniya. Nthawi iliyonse.
