Mainjiniya akamatchula ntchito za fakitale yolondola kwambiri, sikuti amangoyitanitsa magawo - amathandizira kuti pakhale bata pansi pa 300-bar hydraulic load, microstructure integrity pambuyo pa kutentha kwa kutentha, ndi kutsirizitsa kwapamwamba komwe sikungabweretse cavitation m'nyumba zothamanga kwambiri. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., taponyera pa 12,000 zigawo zazitsulo ndi zitsulo zosapanga dzimbiri za mavavu okakamiza, nyumba za silinda pampu ya pisitoni, ndi zodzigudubuza za winch center shaft-chilichonse chimagwira ± 0.05 mm GD&T kulolerana pazinthu zofunika kwambiri. Mlingo wobwerezabwereza umenewo sumachokera ku zipangizo zokha. Zimachokera ku kuwongolera unyolo wonse: chovomerezeka cha AMS 5387 cobalt alloy feedstock, nkhungu zoponyera mchenga zovomerezeka ndi kayeseleledwe kachakudya, makina a CNC omwe amawonetsa ngati ma data-osati zitsanzo zongoyerekeza-ndi kuwunika kwa CMM kusanachitike komanso pambuyo pakuchepetsa kupsinjika.
Chifukwa Chake Kuponya Kwachitsulo Kumafunika Kuphatikizika Koyima—Osati Kungopezako
Ogula ambiri amaganiza kuti "kuponyedwa molondola" kumatanthauza kulolerana kolimba. Chowonadi ndi chokhwima. Mchenga-cast 316 zitsulo zosapanga dzimbiri maziko pampu akhoza kukhala ± 0.3 mamilimita mu chochuluka geometry-koma ake okwera flange anaboola ayenera kugunda ± 0.03 mamilimita kuthamanga * pambuyo* kutentha kutentha ndi Machining komaliza. Apa ndi pamene maunyolo ogawikana amalephera. Wogulitsa m'modzi amaponya. Makina ena. Wachitatu amachita NDT. Chiwopsezo chilichonse chimakhala pachiwopsezo chosokonekera, kusintha kwa data, kapena ma microcracks osanenedwa.
Timayendetsa njira zopangira ndalama komanso mchenga * mkati mwa malo omwewo a ISO 9001 * momwe ma cell athu a CNC a 5-axis amagwira ntchito. Makasitomala akatumiza chojambula cha T800 cobalt alloy nozzle, akatswiri athu amawunikanso * tisanatchule *: Kodi makulidwe a khoma ndi okwanira kupewa kung'ambika kotentha pakukhazikika? Kodi ngodya yojambulira imalola kuti nkhungu ituluke popanda kugaya pambuyo pake zomwe zingasokoneze malo osachita dzimbiri? Kodi gawolo likhoza kukonzedwa kuti lizigwira ntchito zonse pamalo amodzi - kuchotsa cholakwika chowonjezereka?
Izi sizongoyerekeza. Chaka chatha, European hydraulics OEM idatitumizira mawonekedwe osinthidwa a vavu okhala ndi nthiti yamkati ya 2.5-mm. Gulu lathu loyambitsa zidali lidati limakonda kufooketsa porosity. Tinapanga zosindikizira zamtundu wina ndikusintha makina olowera. Zotsatira: ziro zinachepa pa mayunitsi 420, kuyerekeza ndi 27% kukanidwa ndi omwe adawapereka kale.
Mtengo Weniweni Wa "Ingotayani" -Ndipo Chifukwa Chake Kufufuza Kwazinthu Sikoyenera
Mawu ena a fakitale opangira zitsulo amawoneka okakamiza-mpaka mutawona ma certs. Timafunikira malipoti a mill test (MTRs) pa kutentha kulikonse, kulumikizidwa ndi manambala a batch mu ERP yathu. Wogula atatchula AMS 5387 ya pulagi yotentha kwambiri, tidatsata ng'anjo ya vacuum arc remelt ku Germany, osati zolemba za omwe adagawa. Chifukwa chiyani? Chifukwa ma aloyi a cobalt-nickel amakhala kapena kufa ndi kugawa kwa carbide. Kupatuka kwa 5°C mu njira yothetsera kutentha kumasintha kuuma ndi 8 HRB. Popanda chemistry yodziwika bwino komanso mbiri yotentha, mukutchova njuga pa moyo wotopa.
Timakananso njira zazifupi za "standard grade". Ngati nyumba yanu yapampu ikuwona kukwezedwa pamwamba pa 150 MPa, 304 yosapanga dzimbiri siidula - ngakhale itayikidwa bwino bwanji. Timasasintha ku ASTM A743 CF8M kapena 17-4PH yosinthidwa ndi H1150 kukalamba, kutengera kupsinjika ndi kusakanikirana kwamadzimadzi. Chilango chimenecho chimawononga 12-18% yowonjezerapo. Koma zimachotsa zolephera zam'munda zomwe zimawononga 30 × zambiri mu nthawi yopuma, zonena za chitsimikizo, komanso kuwonongeka kwa mbiri.
Zomwe Zimachitika Pakati pa Chojambula Chanu ndi Kutumiza
Mayendedwe athu a ntchito siali mzere-ndikubwerezabwereza:
- Sabata 1: Chitsimikizo cha GD&T + mayankho akupanga. Timayika chizindikiro ngati ma radiyo opyapyala pansi pa 0.8 mm kapena mabowo akhungu akuya kuposa 8× diameter-kenako timapereka malingaliro ena omwe amasunga magwiridwe antchito koma kuchepetsa nthawi yozungulira ndi 35%.
- Sabata 2-3: Kupanga nkhungu + kuponya koyamba. Timatumiza zithunzi za radiographic ndi kusanthula kwa mankhwala—osati malipoti a miyeso.
- Sabata 4: Kuchiza ndi in-process CMM cheke pa ntchito iliyonse. Palibe "kuwunika komaliza kokha."
- Sabata 5: Kuyesa komaliza kogwira ntchito: kuyesa kuwola kwamphamvu mpaka 400 bar, kutsimikizira kuuma kwa ISO 4287, ndi zolemba zonse za traceability.
Timatumiza ma prototypes m'masiku 18. Malamulo apakati (ma PC 50-500) amaperekedwa m'masabata 6-8-ndi masiku okhazikika otsekedwa, osati kuyerekezera kwa imelo.
Factory Precision Casting Steel Imatanthauza Mgwirizano Waumisiri-Osati Kungopanga
Ngati mukufuna fakitale yopangira chitsulo yolondola kwambiri yomwe imatengera zojambula zanu ngati mgwirizano-osati lingaliro-mupeza kuyanjanitsa pa QINGDAO QIANGSENYUAN. Sitithamangitsa voliyumu yotsika mtengo. Timathana ndi njira zolephereka: kukokoloka kwa milomo ya aloyi ya cobalt, kuphulika muzitsulo zazitsulo zosapanga dzimbiri, kupotoza kwazitsulo zazikuluzikulu pambuyo pokonza.
Gawo lathu lotsatira ndikutsimikizira ku AS9100 pakupanga zitsulo zam'mlengalenga ndikukulitsa ma cell athu osakanizidwa opangira makina amtundu wa superalloy wapafupi ndi net. Koma mtengo wamakono suli muzokonzekera zam'tsogolo-zili mu zokolola zoyamba za 99.2% pazigawo zapampu za AMS 5387, 0.02 mm flatness pa 400-mm-diameter zitsulo zosapanga dzimbiri, komanso kuti 73% ya makasitomala athu obwereza akhala akutigwiritsa ntchito kwa zaka zoposa zisanu.
Ngati kulondola kwa dimensional, kukhulupirika kwazinthu, ndi kutsimikizika kwapatsiku sizingakambirane—yambani ndi fakitale yoyezera zitsulo zomwe zimayesa kupambana mu ma microns, osati m'mphepete.
