Pamene mainjiniya afotokoza otsika kuthamanga mchenga kuponyera pazigawo zazitsulo zolondola, samangosankha njira-akusankha nangula wodalirika. Tazionera tokha: nyumba ya pampu ya hydraulic idasweka pakuyezetsa m'munda chifukwa choyambira chidalumpha kukhazikika. Wothandizira wina adachedwetsa kukhazikitsidwa ndi masabata a 11 atalandira nyumba za silinda zosagwirizana ndi ma graphite nodule-zosawoneka popanda zitsulo, koma zimapha pansi pa 350-bar cyclic loading. Ichi ndichifukwa chake "fakitale yotsitsa mchenga wocheperako" si mawu osakira. Ndi fyuluta-yomwe imalekanitsa ogulitsa omwe amamvetsetsa kuwongolera zitsulo kuchokera kwa omwe amangothira zitsulo.
Chifukwa Chake Kuponyera Mchenga Wotsika Kumapereka Kulondola Komwe Mphamvu yokoka Imalephera
Mphamvu yokoka imagwira ntchito pamawonekedwe osavuta. Koma gawo lanu likakhala ndi zigawo zoonda zoyandikana ndi zozama za kutentha kwakukulu - ngati nyumba ya silinda ya pampu ya piston yokhala ndi makulidwe a 4.2 mm yomwe imalowa mkati mwa 68 mm flange - mphamvu yokoka imayambitsa chipwirikiti, kuzimitsa kuzizira, ndikuchepetsa porosity pamipata yovuta kwambiri. Kuponyera kwa mchenga wocheperako kumathetsa izi pogwiritsa ntchito 0.05-0.15 bar ya mpweya wokhazikika wa inert mu mosungiramo zitsulo zosungunuka. Izi zimakakamiza chitsulo kupita m'mwamba kudzera mu chubu chokwera cha ceramic pa liwiro loyendetsedwa (nthawi zambiri 12-18 mm/s), ndikudzaza nkhungu ndi lamina. Chotsatira? Kukhazikika kwachitsogozo kuchokera pansi kupita pamwamba, gasi wotsekeka pafupi ndi ziro, ndi kukhazikika kwamkati mkati mwa ± 0.25 mm pazinthu zofikira 1,200 mm kutalika.
Timatsimikizira izi tsiku ndi tsiku. Pa AMS 5387 cobalt alloy nozzles, kuponyera pang'ono kumakwaniritsa 99.7% kumveka bwino pakuyezetsa akupanga — motsutsana ndi 89% ndi mphamvu yokoka. Chofunika kwambiri, chimapereka kufalikira kwa eutectic carbide. Izi ndizofunikira chifukwa maukonde osagwirizana a carbide amachititsa kuvala msanga m'mayendedwe amadzimadzi othamanga kwambiri. Makasitomala athu omwe ali mumafuta & gasi akuti moyo wautali wautumiki wa 3.2× pa mapulagi opangidwa ndi T800 amapangidwa motere motsutsana ndi njira zina zopangira ndalama - palibe zokutira zomwe zimafunikira.
Mphamvu Zinayi Zosakambirana mu Factory True Low Pressure Sand Casting
Malo ovomerezeka a ISO 9001 ndi magawo a tebulo. Chomwe chimalekanitsa omwe ali okonzeka kuchita nawo ntchito ndi momwe amaphatikizira kutulutsa ndi zofuna zapansi:
- Kufufuza kwazinthu mpaka kutentha nambala: Gulu lililonse la cobalt-nickel alloy limakhala ndi ma MTR athunthu okhala ndi kulimba, kulimba, ndi data ya intergranular corrosion test-osati chemistry yokha.
- Kuwunika kokhazikika kokhazikika: Makamera oyerekeza otenthetsera amatsata kupita patsogolo munthawi yeniyeni; zopatuka zimabweretsa kusintha kwamphamvu kwadzidzidzi kapena kutaya mimba.
- Chitsimikizo chophatikizika cha CMM: Tisanayambe kutsanulira, timasanthula machitidwe apamwamba motsutsana ndi CAD pogwiritsa ntchito Zeiss CONTURA G2, kugwira zolakwika zomwe zingayambitse kuwonongeka kwa ejection.
- Hybrid kumaliza luso: Ma castings amatuluka pa shakeout station ndikupita molunjika ku 5-axis CNC Machining-palibe chogwirira chakunja. Izi zimasunga kukhulupirika kwa datum pazinthu zofunikira za GD&T monga coaxiality pakati pa bore ndi nkhope yokwera (± 0.015 mm).
Ena anganene kuti kuponya mchenga sikungafanane ndi kumalizidwa kwa ndalama. Zowona - pazomaliza zagalasi. Koma kwa malo ogwira ntchito? Ra wathu ngati-cast amakhala pa 12.5 µm pankhope zonyamula katundu, kutsika mpaka 1.6 µm post-machining. Ndizoyenera: zosalala kwambiri zimayitanitsa njala yamafuta m'mapulogalamu otsika kwambiri ngati ma roller a winch center shaft.
Kumene Precision Imakumana ndi Zowona Zogwiritsa Ntchito
Kuponyera kwa mchenga wocheperako kumawala komwe fiziki ndi ntchito zimawombana. Ganizirani za makina opangira ma winch a injini: zodzigudubuza zapakati zimapirira kukameta ubweya wophatikizika, ma radial impact, ndi kuipitsidwa kwa abrasive. Wodzigudubuza woponyera mphamvu yokoka walephera pa mizungu 14,000. Mtundu wathu wocheperako - kugwiritsa ntchito mchenga wobiriwira wosinthidwa wokhala ndi bentonite ndi zowonjezera za kaboni - zidapulumuka mizungu 62,000 pakuyesa kofulumira. Chifukwa chiyani? Kuzizira koyendetsedwa bwino kumasunga 22% ma carbides ochulukirapo m'malo ocheperako, otsimikiziridwa ndi mapu a SEM/EDS.
Kapena tengani ma valve opanikizika a ma hydraulic systems. Makasitomala amafuna kuti musatayike pa bar 420. Njira yathu imakhala ndi kutsetsereka kwa mpando wa pakhomo kufika ku 0.008 mm kudutsa 85 mm m'mimba mwake - zomwe zingatheke chifukwa kutsika kochepa kumathetsa kukokoloka kwa nkhungu chifukwa cha kudzaza kwa chipwirikiti. Timayesa mpando uliwonse wa valve ndi Taylor Hobson PGI Optics, osati zitsanzo chabe.
Kusankha zinthu kumawonjezera ubwino wake. Pamene akuponya T800 cobalt-based alloys, ochiritsira zisamere nkhungu mchenga kusweka ndi mantha matenthedwe. Timagwiritsa ntchito zircon-bonded refractory linings preheated ku 220 ° C-zovomerezeka kudzera mu thermocouple arrays ophatikizidwa mu makoma a nkhungu. Izi zimalepheretsa ma microfissures omwe amakhala malo oyambira ming'alu ya kutopa.
Kusankha Fakitale Yanu Yoponyera Mchenga Wotsika: Yang'anani Kupitilira Kabukuko
Funsani mafunso atatu awa musanasaine PO:
- Kodi mungatiwonetse malipoti ofananirako a geometry yathu yeniyeni-kuphatikiza malo omwe amadziwikiratu komanso momwe amadyetsera bwino?
- Kodi kupatukana kwanu kovomerezeka ndi kotani pakati pa ma-cast ndi makulidwe omaliza pamakina omwe amafunikira onse kuponya kukhulupirika ndi zolimba GD&T?
- Kodi mumatsimikizira bwanji kufanana kwa microstructure pakupanga kumodzi-makamaka pakusintha pakati pa zigawo zokhuthala ndi zoonda?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amayankha onse atatu ndi ndondomeko zolembedwa-osati malonjezo. Malo awo a Qingdao amayendetsa mchenga wotsikirapo pafupi ndi makina a CNC ndi chithandizo cha kutentha pansi pa denga limodzi. Palibe ma handoffs. Palibe kutengeka kwa dimensional. Palibe traceability yotayika. Amathandizira ma OEM aku North America omwe amafunikira ma valavu ogwirizana ndi ASME B16.34, opanga mapampu aku Europe omwe amafunikira zitsulo za EN 10213-G25, komanso omanga zida za migodi ku Southeast Asia omwe amafuna kuponyedwa chitsulo chosamva abrasion — onse ali ndi njira yofananira yachitsulo.
Ngati gawo lanu lotsatira lachitsulo liyenera kupulumuka kupanikizika kwambiri, kuvala kwambiri, kapena kulephera kwamphamvu, yambani ndi otsika kuthamanga mchenga kuponya fakitale zomwe sizimawona kuponya ngati sitepe-koma ngati maziko a umphumphu wogwira ntchito.
