Apo mainjiniya anotsanangura 410 simbi isina tsvina nokuda kwepamusoro-simba, zvinopisa zvinopisa-zvakadai semiviri yevharuvhu ye hydraulic, pombi yepombi, kana mashizha ewinch-havasi kungosarudza chinhu. Vari kuzvipira kune mumwe mugadziri wekugadzira anonzwisisa maitiro e410's martensitic chimiro pasi pekunetseka, kuti kushomeka kwayo kushomeka kunoda kudzorwa kwepamusoro, uye nei batch-to-batch kuomarara kusachinja-chinja kuchikosha kupfuura nhamba dzekusimba chete.
Ndiko uko ruzivo runoparadzanisa vatengesi kubva kumafekitari. At QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., takagadzira zvinopfuura 12,000 410 Stainless simbi zvikamu zveNorth America oilfield pombi maassemblies kubva 2021-imwe neimwe ichida Rockwell C42-48 kuomarara mushure mekudzima uye kudziya, ±0.015 mm geometric kushivirira pakuisa chisimbiso zviso, uye kuzere kuteedzera kune yakabikwa ATM 276 zvinhu. Isu takaona vatengi vachiramba zvikamu nekuda kwekutsemuka-padiki padyo neakapinza mafiritsi mushure mekupisa kupisa-uye takadzidza kugadzirisa maturusi uye pre-kupisa kutenderera zvinoenderana. Isu takaona zvakare vatengi vasingatarise kuti 410's yakaderera nickel yemukati inoita kuti ive ine hanya kune intergranular kurwisa munzvimbo dzakapfuma chloride kunze kwekunge yakapfuura nemazvo. Aya haasi ezvinyorwa zvinyorwa zvepazasi. Zvidzidzo zvemumunda zvakabikwa mune zvese 410 fekitari yesimbi isina tsvina process yatinomhanya.
Precision haisi sarudzo-yakavakirwa mumaitiro ealloy
410 simbi isina tsvina inoburitsa simba kuburikidza nemartensitic shanduko-kwete chromium oxide mafirimu. Izvi zvinoreva kuti kuita kwayo kunotsamira pamatatu akasimba akabatana akasiyana: makemikari kuumbwa (kunyanya kabhoni uye chromium chiyero), nhoroondo yekupisa, uye kupedzisa kwemuchina. Chigayo chakajairwa cert hachivimbisi kusimba kunoenderana. Isu tinobva 410 mabheti akasimbiswa kune AMS 5504 uye tinosimbisa kupisa kwega kwega neOES spectroscopy tisati tagadzira. Kana kabhoni ikadonha pamusoro pe0.15%, tinogadzirisa mitengo yekudzima. Kana chromium ikadzika pasi pe11.5%, tinomisa batch-kunyangwe ikasangana neASTM mishoma-nekuti nyika chaiyo inopfeka hupenyu hunodonha.
Isu tinobatanidza kupisa kurapwa zvakananga muCNC yedu yekufambisa basa. Zvikamu zvinoenda kubva kunzvimbo dzekuchinjisa kuenda kumavira ekutsvaira mukati memaminitsi makumi mapfumbamwe-pasina kuratidzwa kweambient. Kudzima kunoshandisa nitrogen gasi painodzorwa velocity, kwete oiri kana mvura, kubvisa njodzi dzekukanganiswa padzimba dzakatetepa-dzivirirwa silinda. Kupisa kunoitika mukati maawa mana ekudzima, kwete mazuva gare gare. Sei? Nekuti yakachengetwa austenite inoshandura zvisingafungidzike kupfuura iyo hwindo, ichirasa kuoma kwekupedzisira uye kugadzikana kwedimensional. Iyi nhanho yekuranga yemetallurgical haigone kutaurirana kana chikamu chako chikavhara pa3,000 psi kana kutenderera pasi pe15-ton winchi mitoro.
Vertical kubatanidzwa kunogadzirisa izvo outsourcing breaks
Vamwe vatengesi kunze kwekukandira, machining, uye kupisa kurapwa kuparadzanisa vatengesi. Izvo zvinogadzira mapofu mapofu: iyo yekutanga haizive yako GD&T callouts; iyo inopisa-inopisa haigone kuona yako yepamusoro pekupedzisira zvinodiwa; mupedzisi anowana zvikamu zvine chikero chisingaenderani kana decarb layers. Isu tine ese matanho matatu-mune ISO 9001-yakasimbiswa nzvimbo muQingdao.
- Casting: Sand-cast 410 housings ine directional solidification control-kuderedza shrink porosity munzvimbo dzakaoma dzekutakura ne 62% kupesana nemhando dzakajairwa.
- Machining: 5-axis CNC nzvimbo ine-in-processing yechokwadi yekukura kwekupisa panguva yekucheka kwenguva refu pa120-mm-diameter piston rod bores.
- Kupedza: Electropolished surfaces inowana Ra ≤ 0.4 µm panzvimbo yekuvharisa-yakasimbiswa neprofilometer, kwete fungidziro yekuona
Izvi hazvisi zvekubatsira. Zviri pamusoro pekudzivirira kutadza modes hapana mumwe chete mutengesi ane: chirema chekukanda chakafukidzwa nemachining stock, kupisa-kurapa warp kusaverengeka sechikanganiso chekugadzirisa, kana firimu rekufambisa rakabviswa panguva yekubvisa. Paunohodha kubva kune yechokwadi 410 fekitari yesimbi isina tsvina, unowana timu imwe inozvidavirira kune cheni yese-kubva kusimbi yakanyungudutswa kusvika kune inoshanda yekusimbisa.
Chaiyo-yepasirese kusimbiswa inokunda mapepa specs nguva dzese
Isu tinoedza zvikamu mazana mana negumi sevashandisi vekupedzisira-kwete chete kune ASTM zviyero, asi kune kushushikana kwekushandisa. Yese yekumanikidza vharuvhu yedzimba inopinda hydrostatic proof yekuyedza pa 1.5 × yakayerwa kudzvanywa, ine dhayi-inopinda yekuongorora yeese-weld-yekugadzirisa nzvimbo. Yese winch centre shaft roller inomhanyisa 72-awa yakakwirisa kupfeka kutenderera ichipesana neyakaomeswa 42CrMo4 counterfaces-kuyera kurasikirwa kukuru, kushata kwepasi, uye kudzika-kuoma kwegradient. Isu tinonyora mhinduro panhamba yejeti. Iwe unowana iyo data-kwete chete "pasi / kukundikana" chitambi.
Vatengi vanowanzobvunza kuti: "Unogona here kubata ± 0.005 mm pane 300-mm-yakareba 410 shaft?" Hongu-asi chete kana tikaigadzira mumaseti maviri: rough-batidza lathe yakaoma, wozopedzisa-kugaya mushure mekurerutsira-kunetseka pa650°C. Tichakuudza izvozvo mberi. Isu hatizotaura kushivirira isu hatigone kubata mhiri kwemazana mashanu mayunitsi. Uye kana kudhirowa kwako kuchidaidza 0.2-mm radius uko 410's notch senitivity inoda 0.5 mm - isu tinokuratidza iyo yekutyoka mechanics chati uye tokurudzira shanduko tisati tacheka simbi.
Kuvimbika mu410 simbi isina tsvina kunotanga nguva refu chipu chekutanga chisati chabhururuka. Inotanga nekuziva kuti alloy inopindura sei-kwete kuti inofanirwa kupindura sei. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Tinobata zvese 410 fekitari yesimbi isina tsvina odha semubatanidzwa wesimbi. Isu tinopa zvikamu zvakanyatsonaka. Asi zvinonyanya kukosha, isu tinopa kufanotaura-dimensional, mechanic, uye kuburitsa. Nekuti mishoni-yakakosha masisitimu haakundike kubva kune zvakaipa zvinhu. Vanokundikana kubva kune zvisingatarisirwi zvinoshanduka. Uye izvo zvinosiyana zvinogara mune izvo zvatinotonga.
