Pamene mainjiniya afotokoza makina opangira zitsulo ntchito, sikuti amangoyitanitsa magawo - akuteteza kukhazikika kwamphamvu pansi pa 300-bar hydraulic load, microstructure integrity pambuyo pa kutentha kwa kutentha, ndi kutha kwa pamwamba komwe kumatsutsana ndi slurry wonyezimira m'nyumba zopopera mafuta. Ndilo malire omwe ambiri amaphonya. Taziwona mobwerezabwereza: gawo lina limadutsa kuwunika kwa CMM potumizidwa koma limalephera kuyezetsa ntchito pambuyo pa maola 48 akugwira ntchito - chifukwa kugawa kwa nodule kwa graphite sikunatsimikizidwe kupanga makina, kapena chifukwa chotsalira chotsalira chopangidwa ndi makina chinasokoneza bowa panthawi yoyendetsa njinga.
Chifukwa Chake Ma Iron Castings Amafunikira Zambiri Kuposa Kungoponya-Kapena Kungocheka
Zoponyera zitsulo zogwiritsira ntchito molondola-monga nyumba za silinda za pampu ya piston kapena zodzigudubuza za winch center shaft-zimakhala pamphambano zazitsulo ndi geometry. Mchenga-cast ductile iron (ASTM A536 Grade 65-45-12) imapereka mphamvu zamakokedwe komanso mphamvu zochepetsera. Koma mawonekedwe owumbidwa sakhala ndi ± 0.025 mm kulolerana pamabuku onyamula. Ndipamene kuphatikiza koyima kumakhala kosakambitsirana. Pamalo athu ku Qingdao, chitsulo chosaphika chimatsanuliridwa mumchenga nthawi imodzi - ndipo potsatira, zojambulidwazo zimachepetsera kupsinjika, kutembenuka kwa CNC, kenako kumaliza mphero pamakina a 5-axis ndi Renishaw kufufuza. Palibe ma handoffs. Palibe kusanja bwino batch. Palibe zongoyerekeza za ma coefficients owonjezera amafuta pamasitepe amachitidwe.
Tayesa kukhudzidwa kwake: magawo omwe amapangidwa mkati mwa maola 72 akuwonetsa 40% kutsika kwapambuyo popanga makina kuposa omwe amasungidwa kwa milungu iwiri. Chifukwa chiyani? Chifukwa timawongolera mayendedwe oziziritsa kuchokera ku kuthirira mpaka kutulutsa - ndipo timapanga makina mvula isanatseke kupsinjika kwamkati. Izo si chiphunzitso. Ndizomwe zasungidwa pakupanga 1,200+ kuyambira 2019.
Mtengo weniweni wa "Standard" Iron Cast Suppliers
Ogula ena amatenga chitsulo ngati mbale yachitsulo - kalasi ya oda, kupeza cert, kupitilira. Koma pamene thupi lanu la valve lopanikizika liyenera kusindikiza pa 250 ° C pamene likukana kuwonongeka kwa H₂S, ASTM A536 siyokwanira. Muyenera kufufuza mpaka ku ladle chemistry: mpweya wofanana (CE) pakati pa 4.2-4.5, sulfure <0.015%, ndi nodularity>85% yatsimikiziridwa kudzera pa ASTM E2352 metallography-osati mipiringidzo yokhazikika.
Timapeza chitsulo chovomerezeka cha ductile kuchokera kuzinthu zitatu za ISO 9001 zokhala ndi zolemba zala-to-casting traceability. Kutentha kulikonse kumabwera ndi malipoti a spectrometric ndi zithunzi za microstructure. Ngati kasitomala afunsa "chitsulo chogwirizana ndi AMS 5387," sitimalowa m'malo - timafotokozera chifukwa chake ma aloyi a cobalt-nickel amakhala mu nozzles ndi mapulagi, pomwe chitsulo chapamwamba kwambiri chimakhala m'nyumba zonyamula katundu. Kulondola sikungokhudza kulolerana kolimba kokha. Ndizokhudza kufananiza machitidwe akuthupi ndi fizikiki yogwira ntchito.
Zomwe Zimachitika Mkati Mwa Fakitale Yopangira Chitsulo Chochita Kwambiri Kwambiri
Yendani m'malo ogulitsira athu, ndipo muwona maulendo atatu olumikizana omwe akuyenda mofanana:
- Kukonzekera kokonzekera: Kuyerekeza nkhungu (pogwiritsa ntchito MAGMASOFT®) kumatsimikizira mapangidwe a gating musanathire - palibenso zotsekera zoziziritsa pamaziko opaka khoma.
- Kuwongolera makina: Okuma MULTUS U3000 iliyonse imagwiritsa ntchito G-code yovomerezeka motsutsana ndi STEP AP242; Kulipiridwa kwa zida kumasinthira magawo 12 aliwonse pogwiritsa ntchito muyeso wa laser.
- Kuwunika mwamphamvu: Gawo lililonse lofunikira limawunikiridwa katatu-choyamba ndi CMM, chachiwiri ndi chofananira chowoneka bwino, chachitatu chokhala ndi gage yogwira ntchito yofananiza kusokoneza kwenikweni kwa msonkhano.
Palibe sitepe yomwe yalumpha. Palibe "kuwunika komaliza" ndi sitampu ya rabara. Makasitomala akatumiza zithunzi zolemera za GD&T-heavy za ma winch shafts a injiniya, mainjiniya athu amawonetsa kugunda kwa makina * asananene* mawu—osati kudula zidutswa.
Kusankha Wokondedwa Wanu Sizokhudza Geography-Ndizokhudza Ubwana Wanu
Ma OEM aku North America nthawi zambiri amaganiza kuti kuponyera kunyanja kumatanthauza kuchedwa kuyankha kwa NRE kapena chithandizo cha kutentha kosagwirizana. Koma madera a nthawi ndi ofunika kwambiri kusiyana ndi kuyanjanitsa kwaukadaulo. Timayendetsa masinthidwe aukadaulo atsiku ndi tsiku mu Chingerezi, Chisipanishi, ndi Chijeremani—kugwiritsa ntchito mitundu yogawana ya MBD yokhala ndi zizindikiro zenizeni zenizeni. Pamene kampani yaku Europe yopangira ma hydraulics ikufuna mabungwe ogwirizana ndi ISO 13849, tidapanga njira yochepetsera kupsinjika ndi gulu lawo la zida - ndikupereka zolemba za PPAP Level 3 m'masiku 11.
Ndi zotheka chifukwa chathu makina opangira zitsulo sichitulutsa zitsulo, chithandizo cha kutentha, kapena kufufuza komaliza. Ndife eni ake mulu wathunthu—kuchokera ku chitsulo chosungunula kufika pa ukali wa pamwamba Ra ≤0.8 µm pankhope zomata. Ndipo timazilemba zonse: ma cert azinthu, zipika za kutentha, malipoti a CMM, komanso zolemba zoziziritsa za pH zamamizere opangira ma T800-alloy alloy.
Ngati polojekiti yanu yotsatira ikufuna zitsulo zachitsulo zomwe zimapulumuka maulendo a 10,000 pa 200 MPa kukhudzana ndi kupsinjika maganizo-kapena ngati mukutsutsanabe ngati muyambe kuponya kapena makina poyamba-yambani ndi khalidwe lakuthupi, osati zolemba zamalonda. Kulondola kumayambira pomwe chitsulo chimalimba. Zina zonse zimatsatira.
