Pamene mainjiniya afotokoza 410 chitsulo chosapanga dzimbiri pazigawo zamphamvu kwambiri, zowonongeka ndi kutentha-monga matupi a hydraulic valve, nyumba zapampu, kapena mawilo a winchi-samangosankha zinthu. Akupanga mnzake wopanga yemwe amamvetsetsa momwe 410's martensitic imakhalira pansi pa kupsinjika, momwe kukana kwake kwa dzimbiri kumafunikira kuwongolera bwino, komanso chifukwa chiyani kusasinthika kwa batch-to-batch kumafunika kuposa manambala okhazikika okha.
Ndiko kumene zochitika zimalekanitsa ogulitsa kuchokera ku mafakitale. Pa QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tapanga makina opitilira 12,000 410 azitsulo zosapanga dzimbiri pamisonkhano yapampope yaku North America kuyambira 2021-iliyonse imafuna kuuma kwa Rockwell C42-48 pambuyo pozimitsa ndi kutentha, ± 0.015 mm kulolerana kwa geometric pankhope zosindikiza, komanso kutsata kwathunthu kwa ASTM ya A276. Tawona makasitomala akukana magawo chifukwa chang'ono-ng'ono pafupi ndi minofu yakuthwa pambuyo pa chithandizo cha kutentha-ndipo tinaphunzira kusintha njira zogwiritsira ntchito ndi kutentha kusanachitike. Tawonanso ogula anyalanyaza kuti 410 yapansi ya nickel imapangitsa kuti ikhale yovuta kumenyana ndi ma intergranular m'madera olemera kwambiri a chloride pokhapokha ngati atayika bwino. Awa si mawu am'munsi a mabuku. Ndi maphunziro apamwamba omwe amaperekedwa chaka chilichonse 410 fakitale yachitsulo chosapanga dzimbiri ndondomeko timayendetsa.
Kulondola sikosankha - kumapangidwa mumayendedwe a alloy
Chitsulo chosapanga dzimbiri cha 410 chimapereka mphamvu kudzera mukusintha kwa martensitic - osati mafilimu a chromium oxide. Izi zikutanthauza kuti magwiridwe ake amadalira mitundu itatu yolumikizidwa mwamphamvu: kapangidwe kake (makamaka carbon ndi chromium balance), mbiri yamafuta, ndi kumaliza kwamakina. Setifiketi ya mphero yokhazikika sikutsimikizira kuuma kosasinthika. Timapereka ma billets 410 ovomerezeka ku AMS 5504 ndikutsimikizira kutentha kulikonse ndi mawonekedwe a OES musanayambe kukonza. Ngati mpweya ukuyenda pamwamba pa 0.15%, timasintha mitengo yozimitsa. Ngati chromium itsikira pansi pa 11.5%, timayimilira gululi - ngakhale litakwaniritsa zochepa za ASTM - chifukwa mavalidwe adziko lenileni amatsika.
Timaphatikiza chithandizo cha kutentha mwachindunji mumayendedwe athu a CNC. Zina zimachokera ku malo otembenuza kupita ku ng'anjo zotsekera mkati mwa mphindi zosachepera 90 - osawonekera. Kuzimitsa kumagwiritsa ntchito mpweya wa nayitrogeni pa liwiro lolamulirika, osati mafuta kapena madzi, kuchotsa ziwopsezo zopotoka panyumba zokhala ndi mipanda yopyapyala. Kutentha kumachitika mkati mwa maola 4 pambuyo pozimitsa, osati masiku angapo pambuyo pake. Chifukwa chiyani? Chifukwa osungidwa austenite amatembenuka mosayembekezereka kupitirira zeneralo, kutaya kuuma komaliza ndi kukhazikika kwa mawonekedwe. Mulingo uwu waukadaulo wazitsulo sungathe kukambidwa mbali yanu ikasindikiza pa 3,000 psi kapena imazungulira pansi pa katundu wamatani 15.
Kuphatikizika koyima kumathetsa zomwe kutulutsa kwakunja kumasokonekera
Otsatsa ena amatumiza kunja, kukonza makina, ndi chithandizo cha kutentha kuti asiyanitse ogulitsa. Izi zimapanga mawanga akhungu: oyambitsa samadziwa ma callouts anu a GD&T; chotenthetsera sichingathe kuwona zomwe mukufuna kumaliza; womaliza amapeza zigawo zosagwirizana ndi sikelo kapena zigawo za decarb. Tili ndi magawo onse atatu - mu malo amodzi ovomerezeka a ISO 9001 ku Qingdao.
- Kuponya: Mchenga-cast 410 nyumba zokhala ndi zowongolera zolimba-kuchepetsa kuchepa kwa porosity m'malo ovuta kwambiri ndi 62% motsutsana ndi nkhungu wamba
- Machining: Malo a 5-axis CNC omwe ali ndi njira yofufuza zolondola za kukula kwamafuta panthawi yodulira yayitali pa 120-mm-diameter piston rod bores
- Kumaliza: Malo opangidwa ndi ma elekitirodi amakwaniritsa Ra ≤ 0.4 µm pamalo osindikizira - otsimikiziridwa ndi ma profelometer, osati kuyerekezera
Izi sizokhudza kumasuka. Ndi za kupewa njira zolephereka zomwe palibe wogulitsa m'modzi yemwe ali nazo: chilema choponyedwa chophimbidwa ndi makina opangira makina, kusokonekera kwa kutentha kwanthawi yayitali ngati cholakwika, kapena filimu yongoyimitsa yomwe idavulidwa pakuwonongeka. Mukayitanitsa kuchokera ku chowonadi 410 fakitale yachitsulo chosapanga dzimbiri, mumapeza gulu limodzi loyankha pa unyolo wonse-kuchokera kuzitsulo zosungunuka mpaka kutsimikizira ntchito.
Kutsimikizika kwadziko lenileni kumaposa zolemba zamapepala nthawi zonse
Timayesa magawo 410 monga momwe ogwiritsa ntchito amachitira - osati ku miyezo ya ASTM yokha, koma kupsinjika kwa pulogalamu. Nyumba iliyonse ya valve yokakamiza imayesedwa ndi hydrostatic proof pa 1.5 × rated pressure, ndikuwunika kolowera kwa utoto pamadera onse okonza weld. Winch center shaft roller iliyonse imayenda mothamanga kwa maola 72 motsutsana ndi mawonekedwe olimba a 42CrMo4 - kuyeza kutayika kwa anthu ambiri, kusintha kwamphamvu kwapamtunda, komanso kuya kwa kuuma pang'ono. Timalemba zotsatira pa nambala iliyonse. Mumapeza deta-osati sitampu "yodutsa / yolephera".
Makasitomala nthawi zambiri amafunsa kuti: "Kodi mutha kugwira ± 0.005 mm pa shaft ya 300-mm-utali wa 410?" Inde, koma pokhapokha ngati tiyiyika m'magawo awiri: tembenuzani lathe yolimba, kenaka malizani pambuyo pochotsa kupsinjika pa 650 ° C. Tikukuuzani izi posachedwa. Sitingatchule kulolerana komwe sitingathe kukhala ndi mayunitsi 500. Ndipo ngati kujambula kwanu kumafuna utali wa 0.2-mm komwe kukhudzika kwa notch kwa 410 kumafuna 0.5 mm-tidzakuwonetsani tchati cha makina osweka ndikuwonetsa kusintha tisanadule zitsulo.
Kudalirika muzitsulo zosapanga dzimbiri 410 kumayamba kale Chip choyamba chisanawuluke. Zimayamba ndi kudziwa momwe alloy amayankhira-osati momwe amayenera kuyankhira. Pa QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Timachitira chilichonse 410 fakitale yachitsulo chosapanga dzimbiri kulamula ngati mgwirizano wazitsulo. Timapereka magawo olondola. Koma chofunika kwambiri, timapereka zodziwikiratu - zazikulu, zamakina, ndi kutumiza. Chifukwa machitidwe ofunikira a utumwi samalephera kuzinthu zoyipa. Amalephera kuchokera kumitundu yosayendetsedwa. Ndipo zosinthazo zimakhala mwatsatanetsatane zomwe timawongolera.
