Pamene mainjiniya afotokoza 420 chitsulo chosapanga dzimbiri zovala zapamwamba, zosagwira dzimbiri—monga matupi a hydraulic valve, ma shaft a pampu, kapena zodzigudubuza za winchi—zimafunika zambiri kuposa kungotsatira zakuthupi. Amafunika a 420 fakitale yachitsulo chosapanga dzimbiri zomwe zimamvetsetsa momwe chithandizo cha kutentha chimakhudzira kuuma, momwe makina amakhudzira umphumphu wa pamwamba, ndi chifukwa chake kukhazikika kwapang'onopang'ono kumafunika kwambiri kuposa mphamvu zamakanema zokha.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yapanga makina, kuthira kutentha, ndikuyang'ana magawo 12,000 azitsulo zosapanga dzimbiri 420 kuyambira 2018-makamaka pamapampu amafuta aku North America a OEMs ndi ophatikiza ma hydraulic system aku Europe. Tadziwonera tokha momwe kusakhazikika kwa annealing kumabweretsa kung'ung'udza komaliza. Takonza ma callouts a GD&T omwe amaganiza kuti akucheperachepera - koma ma 420 SS ochita masewerawa samachita motero atazimitsa. Ndipo takonzanso zojambula pomwe "galasi lomaliza" lidanenedwa popanda kufotokozera malire a Ra - kungopeza gawo lomwe linalephera kuyezetsa utsi pa maola 96 chifukwa cha kupsinjika kwapansi pamadzi.
Ndicho chifukwa chake kudalirika kumayamba kale chip choyamba chisanawuluke. Ntchito yathu imayamba ndi zitsulo zosapanga dzimbiri 420 zotsimikizika—zomwe zitha kutsatiridwa ndi malipoti a mayeso a mphero omwe akumana ndi ASTM A276 ndi AMS 5630. Timatsimikizira zomwe zili mu kaboni (0.15–0.20%), chromium (12.0–14.0%), ndi kuuma kwanthawi yayitali (≤200 HB) isanadulidwe. Palibe batch yomwe imalowa mukupanga popanda kutsimikizira kwathunthu kwamankhwala ndi ma macro-etch. Chifukwa chiyani? Chifukwa kupatuka kwa kaboni 0.03% kumasintha kutentha koyambira kwa martensite ndi 18 ° C - ndipo izi zimasintha zonse pakuumitsa.
Malo athu ogwirizana ndi ISO amayang'anira mayendedwe athunthu: kutembenuka kolondola kwa CNC ndi mphero (kuphatikiza kuzungulira kwa ma axis angapo pama doko ovuta a valve), kuuma kapena kuuma kwamlengalenga (mpaka 52-56 HRC), kukhazikika kwa cryogenic, ndi kupukuta bwino kwa grit kapena electropolishing pa malo ovuta osindikiza. Timaphatikiza chithandizo cha kutentha mwachindunji mu pulogalamu ya NC-palibe ogulitsa akunja, palibe handoffs, palibe mipata yowunikira. Makasitomala akafuna 54±1 HRC paphewa la pisitoni ya 32-mm, timayezera kuuma pamalo atatu ozungulira * ndi* kuya kwake - osati pamwamba pokha. Izi sizingakambirane pazigawo zomwe zikuyenda pa 3,000 psi zokhala ndi 150,000-cycle zofunika moyo wa kutopa.
- Palibe katundu wapashelufu: Dongosolo lililonse la zitsulo zosapanga dzimbiri 420 limakonzedwa kuchokera kuzinthu zovomerezeka - osati zinyalala zosungunuliridwa kapena zotuluka kunja zosatsimikizika
- Palibe zongoyerekeza: Zinthu zonse zovuta zomwe zatsimikiziridwa pogwiritsa ntchito ma Zeiss CMM zosinthidwa kukhala miyezo yotsatiridwa ndi NIST; GD&T imatanthauziridwa kwathunthu, osati kungoyesa
- Palibe kumaliza kwakhungu: Kuvuta kwapamtunda (Ra, Rz, Rpk) kutsimikiziridwa ndi ASME B46.1-isanayambe kapena itatha-kuonetsetsa kuti kukana kwa dzimbiri kumagwira ntchito
- Palibe kulephera kwa mfundo imodzi: Kutsatiridwa kwathunthu-kuchokera pa nambala ya kutentha kupita ku ID ya ogwiritsa ntchito mpaka sitampu yoyendera nthawi-yomwe ili mu ERP yathu
Ena anganene kuti kuponyera zitsulo zosapanga dzimbiri 420 sikothandiza chifukwa cha chiwopsezo chosweka. Tikuvomereza-ngati mugwiritsa ntchito mchenga wokhala ndi geting wamba. Koma nyumba zathu zopangira ndalama za 420 SS zopangira maziko opopera oyenda pansi pamadzi zimayenda bwino m'madzi a m'nyanja chifukwa timawongolera njira yolimba, kugwiritsa ntchito zigoba za ceramic zomangira silika, ndikuyika ma preheat gradients omwe amachepetsa kutenthedwa kwa kutentha ndi 40%. Simatsenga. Ndi chilango chazitsulo chothandizidwa ndi zaka 11 za chidziwitso cha cobalt-alloy-komwe kasamalidwe ka matenthedwe ndi kupanga kapena kuswa.
Tikudziwanso zomwe chitsulo chosapanga dzimbiri cha 420 * sichichita bwino - ndipo tikuwuzani patsogolo. Sichingafanane ndi 316 SS pakukana kwa chloride pitting. Sikoyenera kuwonetseredwa mosalekeza pamwamba pa 600 ° F. Ndipo ngati kapangidwe kanu kakufuna kuti pakhale ulusi wakuya, wowonda pakhoma pagawo lolimba, tikupangira njira yophera ulusi wotenthedwa m'malo mothamangitsa matepi omwe amathyoka pa 48 HRC. Transparency si lamulo pano. Ndi ukhondo wa uinjiniya.
Kwa makasitomala omwe amayitanitsa ndime yoyamba, kuwunika kwathu kwa uinjiniya kumaphatikizanso mayankho aulere pakupanga: kuzindikira zokwera kupsinjika mukusintha kwa fillet, kutsimikizira kulimba kwa magawo> 25 mm, ndi madera oyika mbendera pomwe electropolishing imatha kukweza ma oxides apamwamba m'malo mowachotsa. Taletsa kukonzanso zida 23 m'miyezi 18 yapitayi-osati kunena "inde," koma kuwonetsa komwe kuli ngozi.
Ngati mukuwerenga 420 fakitale yachitsulo chosapanga dzimbiri othandizana nawo pazantchito zofunika kwambiri zamafakitale, amangoyang'ana kupyola pa ziphaso. Funsani momwe amatsimikizira kuuma kwambiri. Funsani zitsanzo za ma micrograph a magawo okhazikika. Afunseni momwe amachitira ndi kusintha kwakukulu kwa mvula ya chromium carbide. Kenako yerekezerani mayankho.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amapangira moyo wautali-osati masiku obweretsera okha. Cholinga chathu chotsatira: kukulitsa luso la AMS 5630-logwirizana ndi 420 SS lanyumba zoyendetsa ndege ndikupanga makina opangira makina osakanizidwa omwe amadula nthawi yotsogolera ndi 35% popanda kusiya kuwongolera kapangidwe kambewu. Zinthuzi sizinasinthe. Koma momwe timatengera khalidwe lake mozama-ndizo zomwe zimasiyanitsa wogulitsa.
