Pamene mainjiniya afotokoza 17-4 kuponya ndalama kwa mavavu apamwamba a hydraulic hydraulic valves kapena turbine pump housings, samangosankha zinthu-akubetcha pa kukhazikika kwa dimensional, corrosion resistance, ndi microstructural consistency pansi pa njinga yamoto yotentha. Chifukwa chake kusankha koyenera 17 4 fakitale yopanga ndalama zimafunika kwambiri kuposa kutchula mtengo wokha. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., taponyera zida zopitilira 2,300 zapadera za 17-4 PH kuyambira 2019-chilichonse chimafuna kuwongolera kolimba kwa GD&T, kuwunika kwathunthu kwa kutentha, komanso kusagwirizana pa AMS 5643.
Chifukwa chiyani 17-4 PH Imafunikira Zambiri Kuposa Kuyika Kwazachuma Kwanthawi Zonse
17-4 PH chitsulo chosapanga dzimbiri si "chabechabe chosapanga dzimbiri." Khalidwe lake loumitsa mvula limatanthawuza sitepe iliyonse - kuchokera ku geometry ya sera mpaka kukalamba komaliza - zimakhudza mwachindunji mphamvu ya zokolola, moyo wotopa, ndi machinability. Tawona makasitomala akulephera kuyendetsa bwino chifukwa omwe amawagulitsa adagwiritsa ntchito zipolopolo zopangira 316, osati kukulitsa kwamafuta komanso kulimba pang'onopang'ono kwa 17-4 PH. Chotsatira? Micro-shrinkage m'matupi a valve opyapyala, kunja kwa HRC 38-42 pambuyo pa ukalamba wa H900, kapena kusweka kwapamwamba panthawi yopuma kupsinjika maganizo.
Malo athu ovomerezeka a ISO 9001 amayankha izi ndi zodzitchinjiriza zitatu zomangidwira: Choyamba, mapangidwe a zipolopolo za ceramic zomwe zimakonzedweratu kutentha kwa 17-4's 1450 ° C. Chachiwiri, tinjira zozizirirapo zoziziritsa m'kati mwa ng'anjo zothandizira vacuum-palibe kuzimitsa mpweya. Chachitatu, kutsimikizika kovomerezeka kwa CMM pambuyo pa kutentha kwanthawi yayitali pamadatum ovuta makina asanayambe. Ndimomwe timagwirira ± 0.05 mm pa 300 mm diameter popanda kupukuta yachiwiri.
Kuphatikizana Kokhazikika Kumathetsa Zowawa Zopanga Zenizeni
Ogula ambiri amachitira kuponyera ndi CNC ngati ogulitsa osiyana. Izi zimapangitsa kuti pakhale mipata yocheperako: madongosolo olakwika a datum, ndalama zolipirira masheya, kapena kuchedwa kuyankha pakusintha makulidwe a khoma. Pamalo athu a Qingdao, gulu lomwelo la mainjiniya ndilomwe limakhala ndi unyolo wathunthu-kuchokera pakupanga nkhungu mpaka pomaliza.
- Timayika makina onse 17-4 m'nyumba pogwiritsa ntchito 5-axis DMG MORI NTX 1000s, kuthetsa kusamvana kwapakati pa ogulitsa.
- Metallurgists athu amasaina ma chart otenthetsera kutentha okhala ndi ziphaso zakuthupi - batch iliyonse imayambira ku SAE AMS 5604 bar stock
- Kumaliza pamwamba sikungoganiziridwa motsatira: Ra 0.8 µm ndi muyezo pa nkhope zosindikiza; Ra 0.4 µm ikupezeka ndi electropolish-yotsimikiziridwa kudzera pa profilometer, osati kuyerekezera
Kuphatikiza uku kumachepetsa nthawi yotsogolera ndi 37% pamadongosolo apakati (50-500 pcs) ndikuchotsa kukonzanso kuchokera kumalingaliro osagwirizana ndi njira. Pampu imodzi yaku North America OEM idachepetsa kulephera kwamunda ndi 92% mutasintha kuchoka pamitundu iwiri yopereka zinthu kupita ku yankho lathu limodzi la 17-4 PH.
Zomwe Makasitomala Amafunsa Asanapereke Dongosolo Lawo Loyamba
"Kodi mutha kuponyera ngalande zoziziritsira mkati zosachepera 2.5 mm?" Inde, tapanga mabowo akhungu a 1.8 mm m'nyumba za silinda 17-4 pogwiritsa ntchito njira zotayika zotsimikiziridwa ndi mafakitale a CT scan.
"Kodi mumathandizira H1150M + kukalamba kawiri kuti mukhale olimba kwambiri?" Inde, zipika zathu za ng'anjo zimajambulitsa mitengo yokwera, nthawi zonyowa, ndi mbiri yozizirira pagawo lililonse, ndi siginecha ya digito yochokera ku QA ndi zitsulo zotsogola.
"Kodi kuyitanitsa kwanu kocheperako kwa geometry yosakhala wamba?" Palibe MOQ yokhazikika. Timagwiritsa ntchito ma prototypes pamitengo yogawana zipolopolo ngati zotheka - ndikugawana mtengo wa zida mowonekera. Koma sitinganene ngati makulidwe a khoma agwera pansi pa 4.2 mm kapena ma angles ojambulidwa atsika pansi pa 1.5 °. Malire amenewo sakhala achangu; zimatengera 127 zolephera zowunika zomwe zidalembedwa munkhokwe yathu yamkati ya NCMR.
Timayankha mafunso awa patsogolo - osati pa foni yogulitsa, koma mu lipoti lathu lowunikira uinjiniya, loperekedwa mkati mwa maola 72 kuchokera pojambula.
Kuyang'ana M'tsogolo: Komwe Kuyimba Mwachindunji Kukupita Kenako
Mzere wotsatira si zigawo zazikulu-ndizolowera mwanzeru. Tsopano tikuyika zinthu zazing'ono mwachindunji muzoyika 17-4: manambala ojambulidwa ndi laser omwe amatha kuwerengeka pambuyo pa kuwomberedwa, ma groove otsimikizira njira yozizirira, ndi malo osungira opangidwa kale mpaka ± 0.015 mm CNC yomaliza. Izi zimachotsa masitepe a post-cast ndikuchepetsa malo oyendera ndi 60%.
Cholinga chathu cha R&D chimakhalabe chocheperako komanso chakuya: kukhathamiritsa njira zosakanizidwa pomwe kuyika ndalama kumapereka mawonekedwe oyandikira, ndipo makina olondola amawonjezera malo ogwirira ntchito pokhapokha pakufunika. Palibe ma aloyi "ofanana ndi onse". Palibe mankhwala otenthetsera pashelufu. Zongobwerezabwereza, zolembedwa, zowerengeka za 17-4 PH - zoperekedwa kuchokera kumodzi 17 4 fakitale yopanga ndalama ku Qingdao yomwe imagwira pepala lanu ngati mgwirizano, osati lingaliro.
