Zigawo zazitsulo zogwira ntchito kwambiri sizimalora kunyengerera-makamaka pama hydraulic system, ma valve amafuta & gasi, kapena ma winch shafts yamagalimoto. Pamene kukhazikika kwa dimensional, microstructure integrity, ndi kukana kuvala kuyenera kukhala pansi pa 300+ bar pressure kapena 600 ° C kuwonekera kwapakatikati, makina achikhalidwe kapena kuponyera kokha sikulephera. Apa ndipamene ukatswiri wa fakitale ya ufa wa zitsulo umasinthira kuchoka pachosankha kupita pachofunikira-osati ngati njira yokhayokha, koma monga chothandizira njira mkati mwa chilengedwe chophatikizika chophatikizika.
Chifukwa chiyani Powder Metallurgy Yekha Si Yankho (Ndipo Ndi Chiyani)
Mainjiniya ambiri amaganiza kuti "ufa zitsulo" amatanthauza mbali zopindika kuchokera ku makina osindikizira. M'malo mwake, izi sizimapereka kutha kwapamwamba, kulimba kwamphamvu, kapena kutopa komwe kumafunikira panyumba za silinda kapena AMS 5387 cobalt alloy nozzles. Tawonapo njira zitatu zolephera zomwe zimachitika mobwerezabwereza: kutuluka kwa porosity m'matupi a valve opanikizika, kapangidwe ka tirigu kosasinthasintha pamapulagi amtundu wa T800 otenthedwa ndi kutentha, ndi kupatuka kwa GD&T pambuyo popanga makina achiwiri chifukwa cha kuchepa kwamtundu wobiriwira.
Yankho lenileni si kusankha * pakati pa * ufa zitsulo ndi njira wamba—ndi kuwatsata mwanzeru. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Timagwiritsa ntchito zitsulo za ufa osati ngati mapeto, koma ngati gawo lokonzekera bwino. Gawo la aloyi wa cobalt-nickel limayamba ngati lopanda kanthu - kenaka limasunthira molunjika ku makina a 5-axis CNC okhala ndi zida zokongoletsedwa kuti zikhale zotsalira zotsalira. Palibe kukonzanso. Palibe kugwedezeka kwa kutentha kuchokera kumayendedwe osiyana a kutentha. Kungoyenda kamodzi kopitilira kuchokera ku ufa kupita kumalo ogwirira ntchito.
Maluso Anayi Omwe Amasintha zitsulo za Ufa Kukhala Zochita Zolosera
Izi sizongoyerekeza. Imamangidwa m'malo athu ogwirizana ndi ISO ku Qingdao-ndipo yatsimikiziridwa kudutsa ma hydraulic system 127 pazaka zisanu zapitazi. Izi ndi zomwe zimagwira ntchito:
- Kulumikizana kwa Zinthu Zofunika Kuchita Lockstep: Timagwirizanitsa mafotokozedwe a ufa ndi ogulitsa ovomerezeka-osati kungopanga mankhwala, koma kugawa kwa tinthu (D50 = 15-18 µm) ndi flowability (≤25 s / 50g Hall Flow). Chifukwa chiyani? Chifukwa kusiyanasiyana kwa 3% mu kachulukidwe kowoneka bwino kumasintha kuchepa kwa sintering ndi 0.012 mm-zokwanira kuphwanya ± 0.025 mm kulolerana kwa pampu ya piston.
- Machining-Centric Sintering Mbiri: Zozungulira zathu za ng'anjo sizinakhazikitsidwe kuti zikhale zolimba kwambiri. Amakonzedwa kuti azitha kuchita bwino: atagwira pa 1180 ° C kwa mphindi 90 pansi pa argon, kenako kuziziritsa kokhazikika kuti asunge 25-35 HRC yoyambira - yofewa mokwanira kuti zida za carbide zidulidwe bwino, zolimba mokwanira kuti zisagonjetse pomaliza.
- GD&T-Aware Secondary Operations: Gawo lililonse lomwe silinasinthidwe limawunikiridwa ndi CMM * musanapange * makina - osati pambuyo pake. Timajambula geometry yeniyeni yofanana ndi CAD, kenaka timapanga njira zosinthira zomwe zimalipira kuchepa komweko. Zotsatira: 94% zokolola zodutsa koyamba pamakona ovuta ngati ma roller osazungulira a winch center shaft.
- Traceability Kutsika mpaka Pagulu: Chigawo chilichonse chimakhala ndi zolembedwa zonse-osati ma cert azinthu, koma ma sintering atmosphere , malipoti otsimikizira kachulukidwe, ndi kuuma kwapambuyo kwa makina (Ra ≤ 0.4 µm) kuyeza kudzera pa optical profilometry. Palibe zongoganizira. Palibe ma handoffs popanda data.
Kumene Powder Metallurgy Factory Solutions Amapereka ROI
ROI sikutanthauza magawo otsika mtengo. Ndizokhudza kuchotsa njira zolephera zomwe zimawononga kwambiri kutsika. Ganizirani zigawo 6 zapampu za AMS 5387 cobalt 6: kuponyera ndalama zachikhalidwe kumafuna ntchito 7 (chitsanzo cha sera → kumanga zipolopolo → kutenthedwa → kutsanulira → HIP → makina okhwima → makina omaliza). Njira yathu yosakanizidwa imadula mpaka 4 (dinani → sinter → adaptive CNC → kupita komaliza). Nthawi yotsogolera imatsika kuchokera ku masabata a 14 kufika ku 6. Mlingo wa zowonongeka umatsika kuchokera ku 18% kufika ku 3.2%. Ndipo CpK yovuta kwambiri imakhala pamwamba pa 1.67-chifukwa kuchepa sikungochitika mwachisawawa; zimatengera, kuyezedwa, ndi kulipidwa.
Koma kupambana kwakukulu ndi ufulu wopanga. Makasitomala wina waku Europe amafunikira thupi la valve yokakamiza yokhala ndi njira zoziziritsa zamkati zomwe zimadutsa pa 37 ° - zosatheka ndi kukoka pachimake pa mchenga, okwera mtengo kwambiri ndi kubowola kwa EDM muzinthu zogwiritsidwa ntchito. Ufa wazitsulo utiloleza kuti tiyike ma polima operekera nsembe *panthawi ya kukanikiza*, kenako tiziwotcha tisanatenthe. Kukonza makina kunangochotsa zolowera zanga. Nthawi yonse ya chitukuko: masiku 11. Chitsanzo choyamba chogwira ntchito chidadutsa kuphulika kwa 412 bar.
Kusankha Wanu Waufa Metallurgy Factory Partner: Macheke Atatu Osakambirana
Sikuti mafakitale onse a ufa zitsulo amagwira ntchito motere. Musanatumize zojambula, funsani mafunso awa:
- Kodi mumatsimikizira kachulukidwe *pagawo lililonse*—osati kusintha kulikonse? (Ngati anena kuti "inde" koma sangakuwonetseni mawonekedwe a chipika, chokanipo.)
- Kodi opanga mapulogalamu anu a CNC atha kulowetsa fayilo yanu ya STEP * ndi* kuphimba lipoti lanu la CMM kuti apange njira zolipirira? (Ngati pulogalamu yawo ya CAM imagwiritsa ntchito zosoweka ngati zolimba, yembekezerani kukonzanso.)
- Tikatchula AMS 5387 kapena T800, kodi mumapeza ufa kuchokera kwa wothandizira mmodzi woyenerera-ndikugawana malipoti awo oyesa mphero * musanakanize? (Kusiyanasiyana kwa batch-to-batch mu cobalt alloys kumapha kusasinthika mwachangu kuposa chinthu china chilichonse.)
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amakumana onse atatu-ndi kusindikiza sintering ndondomeko zenera kutsimikizira deta mu gawo luso la tsngtaocnc.com. Osati ngati kopi yotsatsa. Monga ma PDF otsitsidwa kuti muwunikenso uinjiniya.
Zigawo zazitsulo zogwira ntchito kwambiri zimachita bwino pamene sayansi ya zida, makina olondola, komanso kuwongolera bwino kumasiya kugwira ntchito m'masilo. Fakitale yopangira zitsulo za ufa yomwe imasindikiza ndi sinter yokha yomwe imapereka zigawo. Imodzi yomwe imagwirizanitsa machitidwe a ufa mu ntchito iliyonse yotsika-kutsimikizira mapangidwe, mapangidwe apangidwe, kupanga zida, kukonzekera kuyendera-imapereka chidaliro. Ndilo gawo lomwe timadutsa tsiku lililonse ku Qingdao. Osati ndi malonjezo. Ndi deta yotsatirika, njira zobwerezabwereza, ndi zigawo zomwe zimakhala ndi mphamvu pamene palibe china chomwe chingathe.
